111-453: The emerald ash borer ( Agrilus planipennis ), also known by the acronym EAB , is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species ( Fraxinus spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. In its native range, it is typically found at low densities and does not cause significant damage to trees native to
222-497: A 4.2-magnitude earthquake occurred on Saturday, May 2, 2015, shortly after noon, about five miles south of Galesburg, Michigan (9 miles southeast of Kalamazoo ) in central Michigan, about 140 miles west of Detroit, according to the Colorado-based U.S. Geological Survey 's National Earthquake Information Center . No major damage or injuries were reported, according to then-Governor Rick Snyder 's office. State government
333-436: A J-shape. These J-shaped larvae shorten into prepupae and develop into pupae and adults the following spring. To exit the tree, adults chew holes from their chamber through the bark, which leaves a characteristic D-shaped exit hole. Immature larvae can overwinter in their larval gallery, but can require an additional summer of feeding before overwintering again and emerging as adults the following spring. This two-year life cycle
444-536: A few hundred feet tall. It is divided by a low water divide running north and south. The larger portion of the state is on the west of this and gradually slopes toward Lake Michigan. The highest point in the Lower Peninsula is either Briar Hill at 1,705 feet (520 m), or one of several points nearby in the vicinity of Cadillac . The lowest point is the surface of Lake Erie at 571 feet (174 m). The geographic orientation of Michigan's peninsulas makes for
555-428: A few types attack green wood; some of these are serious pests capable of killing trees and causing major economic damage, such as the invasive emerald ash borer . Some species are attracted to recently burned forests to lay their eggs. They can sense pine wood smoke from up to 50 miles away, and can see infrared light, helping them to zero in as they get closer to a forest fire . Ten species of flatheaded borers of
666-548: A lab setting. Adults prefer to lay eggs on open grown or stressed ash but readily lay eggs on healthy trees amongst other tree species. Ashes that grow in pure stands, whether naturally occurring or in landscaping, are more prone to attack than isolated trees or ones located in mixed forest stands. Ashes used in landscaping also tend to be subjected to higher amounts of environmental stresses including compacted soil, lack of moisture, heating effects from urban islands , road salt, and pollution, which may also reduce their resistance to
777-526: A lack of available emerald ash borer larvae at the time of adult emergence in spring, limited cold tolerance, and better suitability to regions of North America below the 40th parallel. The USDA is also assessing the application of Beauveria bassiana , an insect fungal pathogen , for controlling emerald ash borer in conjunction with parasitoid wasps. Buprestid Agrilinae Buprestinae Chrysochroinae Galbellinae Julodinae † Parathyreinae Polycestinae (but see text) Buprestidae
888-660: A landmark during the day to safely guide the passenger ships and freighters traveling the Great Lakes (see: lighthouses in the United States ). The state's rivers are generally small, short and shallow, and few are navigable. The principal ones include the Detroit River, St. Marys River, and St. Clair River which connect the Great Lakes; the Au Sable , Cheboygan , and Saginaw , which flow into Lake Huron;
999-563: A long distance between the ends of the state. Ironwood , in the far western Upper Peninsula, lies 630 miles (1,010 kilometers) by highway from Lambertville in the Lower Peninsula's southeastern corner. The geographic isolation of the Upper Peninsula from Michigan's political and population centers makes the region culturally and economically distinct. Frequent attempts to establish the Upper Peninsula as its own state have failed to gain traction. A feature of Michigan that gives it
1110-409: A means of grafting or breeding new, resistant stock. Many of these lingering ashes were found to have unusual phenotypes that may result in increased resistance. Aside from their higher tannin content, Asian ashes also employ natural defenses to repel, trap, and kill emerald ash borer larvae. Although studies of American ashes have suggested that they are capable of mustering similar defensive mechanisms,
1221-489: A monitoring program. These traps can also have volatile pheromones applied to them that attract primarily males. Sometimes trees are girdled to act as trap trees to monitor for emerald ash borer. The stressed tree attracts egg-laying females in the spring, and trees can be debarked in the fall to search for larvae. If detected, an area is often placed under a quarantine to prevent infested wood material from causing new infestations. Further control measures are then taken within
SECTION 10
#17327868051481332-625: A nearly bloodless siege in 1812. A U.S. attempt to retake Detroit resulted in a severe American defeat in the River Raisin Massacre . This battle, still ranked as the bloodiest ever fought in the state, had the highest number of American casualties of any battle of the war. Michigan was recaptured by the Americans in 1813 after the Battle of Lake Erie . They used Michigan as a base to launch an invasion of Canada, which culminated in
1443-430: A permanent community there would strengthen French control over the upper Great Lakes and discourage British aspirations. The hundred soldiers and workers who accompanied Cadillac built a fort enclosing one arpent (about 0.85 acres (3,400 m ), the equivalent of just under 200 feet (61 m) per side) and named it Fort Pontchartrain . Cadillac's wife, Marie Thérèse Guyon, soon moved to Detroit, becoming one of
1554-426: A separate description naming the species as Agrilus marcopoli was published in 1930 by Jan Obenberger . Adult beetles are typically bright metallic green and about 8.5 mm (0.33 in) long and 1.6 mm (0.063 in) wide. Elytra are typically a darker green, but can also have copper hues. Emerald ash borer is the only North American species of Agrilus with a bright red upper abdomen when viewed with
1665-596: A significant amount of population due to global competition and the dramatic unavailability of manufacturing jobs. Meanwhile, Michigan had increased use of technology, specifically when the IBM Personal Computer started selling in the state, in which became mostly used at work. Michigan became the leading auto-producing state in the U.S., with the industry primarily located throughout the Midwestern United States ; Ontario, Canada; and
1776-539: A viable option in urban areas with high value trees near an infestation. Ash trees are primarily treated by direct injection into the tree or soil drench. Some insecticides cannot be applied by homeowners and must be applied by licensed applicators. Damage from emerald ash borer can continue to increase over time even with insecticide applications. Insecticide treatments are not feasible for large forested areas outside of urban areas. The native range of emerald ash borer in Asia
1887-427: A warmer climate ( Köppen climate classification Dfa ) with hot summers and cold winters. The northern part of the Lower Peninsula and the entire Upper Peninsula has a more severe climate (Köppen Dfb ), with warm, but shorter summers and longer, cold to very cold winters. Some parts of the state average high temperatures below freezing from December through February, and into early March in the far northern parts. During
1998-626: Is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers . The family is among the largest of the beetles, with some 15,500 species known in 775 genera . In addition, almost 100 fossil species have been described. The larger and more spectacularly colored jewel beetles are highly prized by insect collectors . The elytra of some Buprestidae species have been traditionally used in beetlewing jewellery and decoration in certain countries in Asia, like India, Thailand and Japan. Shape
2109-846: Is a state in the Great Lakes region of the Upper Midwest region of the United States . It borders Wisconsin to the southwest in the Upper Peninsula , and Indiana and Ohio to the south in the Lower Peninsula ; it is also connected by Lakes Superior , Michigan , Huron , and Erie to Minnesota and Illinois , and the Canadian province of Ontario . With a population of nearly 10.12 million and an area of 96,716 sq mi (250,490 km ), Michigan
2220-534: Is also killed rapidly but usually only after all green and black ash trees are eliminated. Blue ash is known to exhibit a higher degree of resistance to emerald ash borer, which is believed to be caused by the high tannin content in the leaves making the foliage unpalatable to the insect. While most Asian ashes have evolved this defense, it is absent from American species other than blue ash. Researchers have examined populations of so-called "lingering ash", trees that survived ash borer attack with little or no damage, as
2331-573: Is an invasive species that is highly destructive to ash trees in its introduced range. Before emerald ash borer was found in North America, very little was known about the insect in its native range aside from a short description of life-history traits and taxonomic descriptions, which resulted in focused research on its biology in North America. The insect was first identified in Canton, Michigan (near Detroit ), in 2002, but it may have been in
SECTION 20
#17327868051482442-641: Is bounded on the south by the states of Ohio and Indiana , sharing land and water boundaries with both. Michigan's western boundaries are almost entirely water boundaries, from south to north, with Illinois and Wisconsin in Lake Michigan; then a land boundary with Wisconsin and the Upper Peninsula, that is principally demarcated by the Menominee and Montreal Rivers ; then water boundaries again, in Lake Superior, with Wisconsin and Minnesota to
2553-454: Is costly, so slowing down the rate at which trees die through removing known infested trees and treating trees with insecticides can allow local governments more time to plan, remove, and replace trees that would eventually die. This strategy saves money as it would cost $ 10.7 billion in urban areas of 25 states over 10 years, while removing and replacing all ash trees in these same areas at once would cost $ 25 billion (with another estimate putting
2664-403: Is generally cylindrical or elongate to ovoid, with lengths ranging from 3 to 80 mm (0.12 to 3.15 in), although most species are under 20 mm (0.79 in). Catoxantha , Chrysaspis , Euchroma and Megaloxantha contain the largest species. A variety of bright colors are known, often in complicated patterns. The iridescence common to these beetles is not due to pigments in
2775-462: Is generally low. The United States Department of Agriculture 's Animal and Plant Health Inspection Service published a rule on December 14, 2020—to take effect one month later, January 14, 2021—ending all EAB quarantine activities in the United States due to ineffectiveness so far. Other means will be used instead, especially biological controls (see §Biological control below). These insects have managed to eliminate close to 300,000 Ash trees in
2886-489: Is home to the country's three major automobile companies (whose headquarters are all in Metro Detroit). Once exploited for logging and mining, today the sparsely populated Upper Peninsula is important for tourism because of its abundance of natural resources. The Lower Peninsula is a center of manufacturing , forestry , agriculture , services , and high-tech industry. When the first European explorers arrived,
2997-693: Is more common in cool climates, such as European Russia . The native range of the emerald ash borer is temperate north-eastern Asia, which includes Russia, Mongolia, northern China, Japan, and Korea. The beetle is invasive in North America where it has a core population in Michigan and surrounding states and provinces. Populations are more scattered outside the core area, and the edges of its known distribution range north to Ontario , south to northern Louisiana , west to Nebraska , and east to New Brunswick . Satellite populations also exist in Colorado and in
3108-600: Is only a nuisance pest on native trees, as population densities typically do not reach levels lethal to healthy trees. In China, it infests native Fraxinus chinensis , F. mandshurica , and F. rhynchophylla ; in Japan it also infests F. japonica and F. lanuginosa . Emerald ash borer primarily infest and can cause significant damage to ash species including green ash ( F. pennsylvanica ), black ash ( F. nigra ), white ash ( F. americana ), and blue ash ( F. quadrangulata ) in North America. In Europe, F. excelsior
3219-431: Is present. The wasps stun the beetles and carry them back to their burrows in the ground where they are stored until the wasps’ eggs hatch and the wasp larvae feed on the beetles. Volunteers catch the wasps as they return to their burrows carrying the beetles to determine whether emerald ash borer is present. This methodology is known as biological surveillance, as opposed to biological control, because it does not appear that
3330-526: Is rugged. The state's highest point, in the Huron Mountains northwest of Marquette, is Mount Arvon at 1,979 feet (603 m). The peninsula is as large as Connecticut, Delaware, Massachusetts, and Rhode Island combined but has fewer than 330,000 inhabitants. The people are sometimes called "Yoopers" (from "U.P.'ers"), and their speech (the " Yooper dialect ") has been heavily influenced by the numerous Scandinavian and Canadian immigrants who settled
3441-562: Is the 10th-largest state by population, the 11th-largest by area, and the largest by area east of the Mississippi River . Its capital is Lansing , and its largest city is Detroit . Metro Detroit is among the nation's most populous and largest metropolitan economies. The name derives from a gallicized variant of the original Ojibwe word ᒥᓯᑲᒥ ( mishigami ), meaning "large water" or "large lake". Michigan consists of two peninsulas . The Lower Peninsula resembles

3552-556: Is the main ash species colonized, which is moderately resistant to emerald ash borer infestation. Ash susceptibility can vary depending on the attractiveness of chemical volatiles to adults, or the ability of larvae to detoxify phenolic compounds. Emerald ash borer has also been found infesting white fringe tree in North America, which is a non-ash host, but it is unclear whether the trees were healthy when first infested, or were already in decline because of drought. Another non-ash host has also been discovered, Olea europaea , albeit in
3663-521: Is the state's largest metropolitan area (roughly 50% of the population resides there) and the eleventh largest in the United States. The Grand Rapids metropolitan area in Western Michigan is the state's fastest-growing metro area, with more than 1.3 million residents as of 2006 . Michigan consists of two peninsulas separated by the Straits of Mackinac . The 45th parallel north runs through
3774-560: The American Revolution . When Quebec split into Lower and Upper Canada in 1791, Michigan was part of Kent County , Upper Canada. It held its first democratic elections in August 1792 to send delegates to the new provincial parliament at Newark (now Niagara-on-the-Lake ). Under terms negotiated in the 1794 Jay Treaty , Britain withdrew from Detroit and Michilimackinac in 1796. It retained control of territory east and south of
3885-710: The Battle of the Thames . But the more northern areas of Michigan were held by the British until the peace treaty restored the old boundaries. A number of forts, including Fort Wayne , were built by the United States in Michigan during the 19th century out of fears of renewed fighting with Britain. Michigan Territory governor and judges established the University of Michigan in 1817, as the Catholepistemiad, or
3996-551: The Guardian Building , each of which has been designated as a National Historic Landmark (NHL). In 1927 a school bombing took place in Clinton County . The Bath School disaster resulted in the deaths of 38 schoolchildren and constitutes the deadliest mass murder in a school in U.S. history. Michigan converted much of its manufacturing to satisfy defense needs during World War II ; it manufactured 10.9% of

Although Michigan has developed a diverse economy, in the early 20th century it became widely known as the center of the U.S. automotive industry , which developed as a major national economic force. It
4218-560: The North Country National Scenic Trail passes through Michigan. With 78 state parks , 19 state recreation areas, and six state forests , Michigan has the largest state park and state forest system of any state. Michigan has a continental climate with two distinct regions. The southern and central parts of the Lower Peninsula (south of Saginaw Bay and from the Grand Rapids area southward) have

No point in Michigan is more than six miles (9.7 km) from an inland lake or more than 85 miles (137 km) from one of
4440-487: The automotive industry . Ford's development of the moving assembly line in Highland Park marked a new era in transportation. Like the steamship and railroad, mass production of automobiles was a far-reaching development. More than the forms of public transportation, the affordable automobile transformed private life. Automobile production became the major industry of Detroit and Michigan, and permanently altered

Insecticides with active ingredients such as azadirachtin , imidacloprid , emamectin benzoate , and dinotefuran are currently used. Dinotefuran and imidacloprid are systemic (i.e., incorporated into the tree) and remain effective for one to three years depending on the product. Insecticides are typically only considered
4773-437: The 1830s, Michigan had 30,000 residents, more than enough to apply and qualify for statehood. On November 1, 1935, the U.S. Post Office issued a commemorative 3-cent stamp celebrating the 100th anniversary of Michigan statehood. Michigan's statehood, however, wasn't officially established until January 26, 1837, but since the campaign for statehood actually began in 1835, Michigan chose to hold its centennial celebration in 1935,
4884-851: The British forces, ending the French and Indian War (1754–1763), the North American front of the Seven Years' War in Europe. Under the 1763 Treaty of Paris , Michigan and the rest of New France east of the Mississippi River were ceded by defeated France to Great Britain. After the Quebec Act was passed in 1774, Michigan became part of the British Province of Quebec . By 1778, Detroit's population reached 2,144 and it

Questions remained over the boundary for many years, and the United States did not have uncontested control of the Upper Peninsula and Drummond Island until 1818 and 1847, respectively. During the War of 1812 , the United States forces at Fort Detroit surrendered Michigan Territory (effectively consisting of Detroit and the surrounding area) after
5106-685: The French established a trading post and Fort St. Joseph along the St. Joseph River at the present-day city of Niles . In 1701, French explorer and army officer Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit or "Fort Pontchartrain on-the-Strait" on the strait, known as the Detroit River , between lakes Saint Clair and Erie . Cadillac had convinced King Louis XIV's chief minister, Louis Phélypeaux, Comte de Pontchartrain , that

No point in the state is more than six miles (9.7 km) from a natural water source or more than 85 miles (137 km) from a Great Lakes shoreline. The Great Lakes that border Michigan from east to west are Lake Erie , Lake Huron , Lake Michigan and Lake Superior . The state
5439-548: The National Capital Region in only nine years. This leaves only 80,000 ash trees left standing either due to luck or to some amount of resistance to the beetles. These forests used to have an extremely dense Ash population having 17-18 trees per Hectare now there are only 5-6 trees per Hectare. This illustrates extremely well the overall destructive power of the Emerald Ash Borer and the relevance to
5550-686: The Pacific Northwest in Oregon . In eastern Europe, a population was found in Moscow in 2003. From 2003 to 2016, this population has spread west towards the European Union at up to 40 km (25 mi) per year and is expected to reach central Europe between 2031 and 2036. Although not recorded from the European Union as of 2019, it has already spread to far eastern Ukraine from neighboring Russia. In its native range, emerald ash borer
5661-548: The Southern United States. With almost ten million residents in 2010, Michigan is a large and influential state, ranking tenth in population among the fifty states. Detroit is the centrally located metropolitan area of the Great Lakes megalopolis and the second-largest metropolitan area in the U.S. (after Chicago ) linking the Great Lakes system. The Metro Detroit area in Southeast Michigan

#17327868051485772-884: The U.S. since the late 1980s. It is suspected that it was introduced from overseas in shipping materials such as packing crates. Without factors that would normally suppress emerald ash borer populations in its native range (e.g., resistant trees, predators, and parasitoid wasps ), populations can quickly rise to damaging levels. After initial infestation, all ash trees are expected to die in an area within 10 years without control measures. Every North American ash species has susceptibility to emerald ash borer, as North American species planted in China also have high mortality from infestations, but some Asian ash species are resistant, including F. baroniana , F. chinensis, F. floribunda , F. mandshurica , and F. platypoda . Green ash and black ash trees are preferred by emerald ash borer. White ash

Detroit continued to expand through the 1950s, at one point doubling its population in a decade. After World War II, housing was developed in suburban areas outside city cores to meet demand for residences. The federal government subsidized the construction of interstate highways , which were intended to strengthen military access, but also allowed commuters and business traffic to travel
6105-697: The University of Michigania. The population grew slowly until the opening in 1825 of the Erie Canal through the Mohawk Valley in New York, connecting the Great Lakes to the Hudson River and New York City. The new route attracted a large influx of settlers to the Michigan territory. They worked as farmers, lumbermen, shipbuilders, and merchants and shipped out grain, lumber, and iron ore. By

Britain ceded the territory to the newly independent United States after its defeat in the American Revolutionary War . The area was part of the larger Northwest Territory until 1800, when western Michigan became part of the Indiana Territory . Michigan Territory
6660-467: The area. Outside its native range, it is an invasive species and is highly destructive to ash trees native to Europe and North America. Before it was found in North America, very little was known about the emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America. Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, and through

7992-535: The five Great Lakes and Lake St. Clair . It also has 64,980 inland lakes and ponds . Michigan has the second-most water area of any state, behind only Alaska. The area was first occupied by a succession of Native American tribes over thousands of years. In the 17th century, French explorers claimed it as part of the New France colony, when it was largely inhabited by Indigenous peoples. French and Canadian traders and settlers, Métis , and others migrated to
8103-576: The foliage, small rodents amongst the roots, etc. Emerald ash borer threatens the entire North American genus Fraxinus . It has killed tens of millions of ash trees so far and threatens to kill most of the 8.7 billion ash trees throughout North America. Emerald ash borer kills young trees several years before reaching their seeding age of 10 years. In both North America and Europe, the loss of ash from an ecosystem can result in increased numbers of invasive plants, changes in soil nutrients, and effects on species that feed on ash. Damage and efforts to control
8214-565: The fur trade led to the Fox Wars , in which the Meskwaki (Fox) and their allies fought the French and their Native allies. At the same time, the French strengthened Fort Michilimackinac at the Straits of Mackinac to better control their lucrative fur-trading empire. By the mid-18th century, the French also occupied forts at present-day Niles and Sault Ste. Marie, though most of the rest of
8325-425: The larvae disrupt the flow of nutrients and water, effectively girdling , thus killing the tree, as it is no longer able to transport sufficient water and nutrients to the leaves to survive. Girdled ashes will often attempt to regenerate through stump sprouting, and there is evidence that stressed trees may also generate higher than normal seed crops as an emergency measure. Outside its native range, emerald ash borer
8436-708: The late 19th to early 20th century, working in lumbering areas in counties on the Lake Huron side of the Lower Peninsula, such as the Saginaw Valley, Alpena, and Cheboygan counties, as well as throughout the Upper Peninsula, with large concentrations in Escanaba and the Keweenaw Peninsula . The first statewide meeting of the Republican Party took place on July 6, 1854, in Jackson, Michigan , where
8547-428: The main infestation. Other factors can limit spread. Winter temperatures of approximately −38 °C (−36 °F) limit range expansion, and overwintering emerald ash borer survive down to average temperatures of −30 °C (−22 °F) because of antifreeze chemicals in the body and insulation provided by tree bark. Larvae can also survive high heat up to 53 °C (127 °F). Conversely, much like ashes grown in
8658-459: The material could be infested. Kentucky Extension specialists suggest selecting uncommon species to replace removed ashes in the landscape. Previous generations created monocultures by planting ash trees in an overabundance, a factor in the extent of the devastation caused by the emerald ash borer. Favoring instead a diversity in species helps keep urban forests healthy. University of Kentucky scientists suggest choosing monotypic species such as
8769-579: The material has been inspected or treated (i.e., heat treatment or wood chipping) to ensure no live emerald ash borer are present in the bark and phloem. In urban areas, trees are often removed once an infestation is found to reduce emerald ash borer population densities and the likelihood of further spread. Urban ash are typically replaced with non-ash species such as maple, oak, or linden to limit food sources. In rural areas, trees can be harvested for lumber or firewood to reduce ash stand density, but quarantines may apply for this material, especially in areas where
8880-673: The most populous tribes were the Algonquian peoples , which include the Anishinaabe groups of Ojibwe , Odaawaa/Odawa (Ottawa) , and the Boodewaadamii/Bodéwadmi (Potawatomi) . The three nations coexisted peacefully as part of a loose confederation called the Council of Three Fires . The Ojibwe, whose numbers are estimated to have been at least 35,000, were the largest. The Ojibwe Indians (also known as Chippewa in
8991-456: The nation. Many private colleges were founded as well, and the smaller cities established high schools late in the century. Michigan's economy underwent a transformation at the turn of the 20th century. Many individuals, including Ransom E. Olds , John and Horace Dodge , Henry Leland , David Dunbar Buick , Henry Joy , Charles King , and Henry Ford , provided the concentration of engineering know-how and technological enthusiasm to develop
9102-479: The nursery trade, the population of emerald ash borer in North America is believed to have originated from a single group of insects from central China and also exhibits low genetic diversity. North American predators and parasitoids can occasionally cause high emerald ash borer mortality, but generally offer only limited control. Mortality from native woodpeckers is variable. Parasitism by parasitoids such as Atanycolus cappaerti can be high, but overall such control
9213-419: The other three species have been documented parasitizing emerald ash borer larvae one year after release, indicating that they survived the winter, but establishment varied among species and locations. Tetrastichus planipennisi and Oobius agrili established and have had increasing populations in Michigan since 2008; Spathius agrili has had lower establishment success in North America, which could be caused by
9324-682: The party adopted its platform. The state was predominantly Republican until the 1930s, reflecting the political continuity of migrants from across the Northern Tier of New England and New York. Michigan made a significant contribution to the Union in the American Civil War and sent more than forty regiments of volunteers to the federal armies. Michigan modernized and expanded its system of education in this period. The Michigan State Normal School, now Eastern Michigan University ,
9435-441: The population boom. By the 1930s, so many immigrants had arrived that more than 30 languages were spoken in the public schools, and ethnic communities celebrated in annual heritage festivals. Over the years immigrants and migrants contributed greatly to Detroit's diverse urban culture, including popular music trends. The influential Motown Sound of the 1960s was led by a variety of individual singers and groups. Grand Rapids ,
9546-546: The principal ones being the North Manitou and South Manitou , Beaver , and Fox groups in Lake Michigan; Isle Royale and Grande Isle in Lake Superior; Marquette, Bois Blanc , and Mackinac islands in Lake Huron; and Neebish , Sugar , and Drummond islands in St. Mary's River . Michigan has about 150 lighthouses , the most of any U.S. state. The first lighthouses in Michigan were built between 1818 and 1822. They were built to project light at night and to serve as
9657-587: The region more easily. Since 1960, modern advances in the auto industry have led to increased automation, high-tech industry, and increased suburban growth. Longstanding tensions in Detroit culminated in the Twelfth Street riot in July 1967. During the late 1970s and the early 1980s, increasing fuel costs and other factors made significantly more global competition and recession among families. Michigan lost
9768-517: The region remained unsettled by Europeans. France offered free land to attract families to Detroit, which grew to 800 people in 1765. It was the largest city between Montreal and New Orleans. French settlers also established small farms south of the Detroit River opposite the fort, near a Jesuit mission and Huron village. From 1660 until the end of French rule, Michigan was part of the Royal Province of New France . In 1760, Montreal fell to
9879-462: The removal alone at $ 20–60 billion). Some urban areas such as Minneapolis have large amounts of ash with slightly more than 20% of their urban forest as ash. In areas where emerald ash borer has not yet been detected, surveys are used to monitor for new infestations. Visual surveys are used to find ash trees displaying emerald ash borer damage, and traps with colors attractive to emerald ash borer, such as purple or green, are hung in trees as part of
9990-528: The second-largest city in Michigan also became an important center of manufacturing. Since 1838, the city has been noted for its furniture industry. In the 21st century, it is home to five of the world's leading office furniture companies. Grand Rapids is home to a number of major companies including Steelcase , Amway , and Meijer . Grand Rapids is also an important center for GE Aviation Systems . Michigan held its first United States presidential primary election in 1910. With its rapid growth in industry, it
10101-435: The shape of a mitten , and comprises a majority of the state's land area. The Upper Peninsula (often called "the U.P.") is separated from the Lower Peninsula by the Straits of Mackinac , a five-mile (8 km) channel that joins Lake Huron to Lake Michigan. The Mackinac Bridge connects the peninsulas. Michigan has the longest freshwater coastline of any political subdivision in the United States, being bordered by four of
10212-418: The socioeconomic life of the United States and much of the world. With the growth, the auto industry created jobs in Detroit that attracted immigrants from Europe and migrants from across the United States, including both blacks and whites from the rural South . By 1920, Detroit was the fourth-largest city in the U.S.. Residential housing was in short supply, and it took years for the market to catch up with
10323-888: The south and east, were the Mascouten , the Menominee , the Miami , the Sac (or Sauk), and the Meskwaki (Fox) . The Wyandot were an Iroquoian-speaking people in this area; they were historically known as the Huron by the French, and were the historical adversaries of the Iroquois Confederation . French voyageurs and coureurs des bois explored and settled in Michigan in the 17th century. The first Europeans to reach what became Michigan were those of Étienne Brûlé 's expedition in 1622. The first permanent European settlement
10434-518: The spread of emerald ash borer have affected businesses that sell ash trees or wood products, property owners, and local or state governments. Quarantines can limit the transport of ash trees and products, but economic impacts are especially high for urban and residential areas because of treatment or removal costs and decreased land value from dying trees. Costs for managing these trees can fall upon homeowners or local municipalities. For municipalities, removing large numbers of dead or infested trees at once
10545-596: The state, marked by highway signs and the Polar-Equator Trail— along a line including Mission Point Light near Traverse City , the towns of Gaylord and Alpena in the Lower Peninsula and Menominee in the Upper Peninsula. With the exception of two tiny areas drained by the Mississippi River by way of the Wisconsin River in the Upper Peninsula and by way of the Kankakee - Illinois River in
10656-462: The time of year of oviposition , the health of the tree, and temperature. After 400–500 accumulated degree-days above 10 °C (50 °F), adults begin to emerge from trees in late spring, and peak emergence occurs around 1,000 degree-days. After emergence, adults feed for one week on ash leaves in the canopy before mating, but cause little defoliation in the process. Males hover around trees, locate females by visual cues, and drop directly onto
10767-760: The trees do not appear to recognize when they are under attack. Many of the specialized predators and parasitoids that suppressed emerald ash borer in Asia were not present in North America. Predators and parasitoids native to North America do not sufficiently suppress emerald ash borer, so populations continue to grow. Birds such as woodpeckers feed on emerald ash borer larva, although the adult beetles have not been used by any American fauna as food. Emerald ash borer populations can spread between 2.5 to 20 km (1.6 to 12.4 mi) per year. It primarily spreads through flight or by transportation of ash bark containing products such as firewood or nursery stock, which allows it to reach new areas and create satellite populations outside of
10878-552: The use of insecticides and biological control . French priest and naturalist Armand David collected a specimen of the species during one of his trips through Imperial China in the 1860s and 1870s. He found the beetle in Beijing and sent it to France, where the first brief description of Agrilus planipennis by the entomologist Léon Fairmaire was published in the Revue d'Entomologie in 1888. Unaware of Fairmaire's description,
10989-598: The very southern portions of the state have tornado sirens to warn residents of approaching tornadoes. Farther north, in Central Michigan, Northern Michigan, and the Upper Peninsula, tornadoes are rare. The geological formation of the state is greatly varied, with the Michigan Basin being the most major formation. Primary boulders are found over the entire surface of the Upper Peninsula (being principally of primitive origin), while Secondary deposits cover
11100-480: The wasps have a significant negative impact on emerald ash borer populations. In areas where emerald ash borer is non-native and invasive, quarantines, infested tree removal, insecticides, and biological control are used to reduce damage to ash trees. Once an infestation is detected, quarantines are typically imposed by state, or previously, national government agencies disallowing transport of ash firewood or live plants outside of these areas without permits indicating
11211-512: The west, capped around by the Canadian province of Ontario to the north and east. The heavily forested Upper Peninsula is relatively mountainous in the west. The Porcupine Mountains , which are part of one of the oldest mountain chains in the world, rise to an altitude of almost 2,000 feet (610 m) above sea level and form the watershed between the streams flowing into Lake Superior and Lake Michigan. The surface on either side of this range
11322-497: The western part of the Upper Peninsula as a concession and formally entered the Union as a free state on January 26, 1837. The Upper Peninsula proved to be a rich source of lumber, iron, and copper. Michigan led the nation in lumber production from the 1850s to the 1880s. Railroads became a major engine of growth from the 1850s onward, with Detroit the chief hub . A second wave of French-Canadian immigrants settled in Michigan during
11433-400: The wings and elytra spread. The species also has a small spine found at the tip of the abdomen and serrate antennae that begin at the fourth antennal segment. They leave tracks in the trees they damage below the bark that are sometimes visible. Adult beetles of other species can often be misidentified by the public. The emerald ash borer life cycle can occur over one or two years depending on
11544-432: The winter through the middle of February, the state is frequently subjected to heavy lake-effect snow . The state averages from 30 to 40 inches (76 to 102 cm) of precipitation annually; however, some areas in the northern lower peninsula and the upper peninsula average almost 160 inches (4,100 mm) of snowfall per year. Michigan's highest recorded temperature is 112 °F (44 °C) at Mio on July 13, 1936, and
11655-462: The year the stamp was first issued. A constitutional convention of assent was held to lead the territory to statehood. In October 1835 the people approved the constitution of 1835, thereby forming a state government. Congressional recognition was delayed pending resolution of a boundary dispute with Ohio known as the Toledo War . Congress awarded the "Toledo Strip" to Ohio. Michigan received
11766-549: Was an important center of industry-wide union organizing, such as the rise of the United Auto Workers . In 1920 WWJ (AM) in Detroit became the first radio station in the United States to regularly broadcast commercial programs. Throughout that decade, some of the country's largest and most ornate skyscrapers were built in the city. Particularly noteworthy are the Fisher Building , Cadillac Place , and
11877-418: Was formed in 1805, but some of the northern border with Canada was not agreed upon until after the War of 1812 . Michigan was admitted into the Union in 1837 as the 26th state, a free one . It soon became an important center of industry and trade in the Great Lakes region, attracting immigrants in the late 19th and early 20th centuries from many European countries . Immigrants from Finland , Macedonia , and
11988-438: Was founded in 1668 on the site where Père Jacques Marquette established Sault Ste. Marie, Michigan , as a base for Catholic missions. Missionaries in 1671–75 founded outlying stations at Saint Ignace and Marquette . Jesuit missionaries were well received by the area's Indian populations, with few difficulties or hostilities. In 1679, Robert Cavelier, Sieur de la Salle built Fort Miami at present-day St. Joseph . In 1691,
12099-577: Was founded in 1849, for the training of teachers. It was the fourth oldest normal school in the United States and the first U.S. normal school outside New England . In 1899, the Michigan State Normal School became the first normal school in the nation to offer a four-year curriculum. Michigan Agricultural College (1855), now Michigan State University in East Lansing , was founded as the first agricultural college in
12210-597: Was surveyed for parasitoid species that parasitize emerald ash borer and do not attack other insect species in the hope they would suppress populations when released in North America. Three species imported from China were approved for release by the USDA in 2007 and in Canada in 2013: Spathius agrili , Tetrastichus planipennisi , and Oobius agrili , while Spathius galinae was approved for release in 2015. Excluding Spathius galinae , which has only recently been released,
12321-501: Was the third-largest city in Quebec province. During the American Revolutionary War , Detroit was an important British supply center. Most of the inhabitants were French-Canadians or American Indians, many of whom had been allied with the French because of long trading ties. Because of imprecise cartography and unclear language defining the boundaries in the 1783 Treaty of Paris , the British retained control of Detroit and Michigan after
