Each iteration included plans to pave
13800-556: The country's GDP. The U.S. has 42% of the world's nuclear weapons —the second-largest share after Russia.

State defense forces (SDFs) are military units that operate under
13950-469: The country's territory would expand with the admission of new states , rather than the expansion of existing states. The U.S. Constitution was drafted at the 1787 Constitutional Convention to overcome the limitations of the Articles.

14100-713: The development of self-governance, and the First Great Awakening , a series of Christian revivals , fueled colonial interest in religious liberty . For a century, the American colonists had been providing their own troops and materiel in conflicts with indigenous peoples allied with Britain's colonial rivals , especially France, and the Americans had begun to develop a sense of self-defense and self-reliance separate from Britain. The French and Indian War (1754–1763) took on new significance for all North American colonists after Parliament under William Pitt
14250-611: The difficulties of managing elk populations in Yellowstone National Park and how "overprotection from natural ground fires" in California's Sequoia National Park , Kings Canyon National Park , and Yosemite National Park had begun to threaten groves of Giant Sequoia with catastrophic wildfires.

14400-534: The dispossession of native inhabitants . As more states were admitted , a North–South division over slavery led to the secession of the Confederate States of America , which fought states remaining in the Union in the 1861–1865 American Civil War .

14550-413: The ecologic scene as viewed by the first European visitors." This baseline would guide ecological restoration in national parks until a climate change adaptation policy, "Resist-Adapt-Direct", was established in 2021.

Here, the iconic species of Joshua Tree National Park is a leading example. The three RAD options are: The "Resist-Accept-Direct" Framework is first described in a July 2020 paper published in Fisheries Eighteen researchers from federal and state agencies and universities collaborated in this effort, which included short case studies of where and how this framework has already been applied. The National Park System includes all properties managed by

The Trail of Tears (1830–1850) was a U.S. government policy that forcibly removed and displaced most Native Americans living east of the Mississippi River to lands far to the west.

A societal shift in the roles of women was significantly responsible for the large increase in female paid labor participation during the 1970s, and by 1985 the majority of American women aged 16 and older were employed. The late 1980s and early 1990s saw
16350-612: The most attractive to the population are the most vulnerable. The U.S. is one of 17 megadiverse countries containing large numbers of endemic species : about 17,000 species of vascular plants occur in the contiguous United States and Alaska, and over 1,800 species of flowering plants are found in Hawaii, few of which occur on the mainland. The United States is home to 428 mammal species, 784 birds, 311 reptiles, 295 amphibians , and around 91,000 insect species.

States in the North enacted abolition laws , though support for slavery strengthened in Southern states , as inventions such as
16800-573: The next month advocates chose the name "Capital Crescent Trail." The last train ran on the line in June 1985, when Chessie officials determined that one of its bridges was unsafe. At that time, the only customers were the General Services Administration, which used the railroad to bring coal to a heating plant at 29th and K streets, and a small building-supply company in Bethesda. Three months later, and shortly after 75 feet of
16950-492: The opening was set for fall 2026. The trail could be opened before the trains run, but a tunnel through Bethesda will also not be completed until 2026. In 2024, the projected opening date for the trail - which had been listed as spring 2027 - was moved up to spring 2026. The currently closed section of the trail started at Lyttonsville Junction , about one mile (1.6 km) west of downtown Silver Spring. It went west on an unpaved, crushed-stone surface passing over Rock Creek on
17100-553: The original Leopold Report. The committee published their 23-page report in 2012, titled, "Revisiting Leopold: Resource Stewardship in the National Parks". The report recommended that parks leadership "manage for change while confronting uncertainty." "... New and emerging scientific disciplines — including conservation biology, global change science, and genomics — along with new technological tools like high-resolution remote sensing can provide significant information for constructing contemporary tactics for NPS stewardship. This knowledge
17250-400: The overall visits. The top 10 percent of parks (43) handle over 64 percent of all visits, leaving the remaining more than 380 units to accommodate around 36 percent of visits. (Note that only 380 sites recorded visitors during 2021 due to COVID-19-related closures). Most areas of the National Park System do not charge entrance fees and are completely supported by tax dollars, although some of
17400-408: The policy of redlining later adopted by the federal Home Owners' Loan Corporation . An explosion of technological advancement accompanied by the exploitation of cheap immigrant labor led to rapid economic expansion during the late 19th and early 20th centuries , allowing the United States to outpace the economies of England, France, and Germany combined. This fostered the amassing of power by
17550-480: The president the authority to transfer national monuments from one governmental department to another. Later that summer, new president Franklin D.

The D.C. section then became
18000-516: The rail line were damaged in flooding , Chessie officials said that they would formally request ICC permission to abandon the line.
