78-874: Last Mountain Lake National Wildlife Area is a National Wildlife Area (NWA) in the Canadian province of Saskatchewan . The protected area is in the Prairie Pothole Region of North America , which extends throughout three Canadian provinces and five U.S. states . It is also within Palliser's Triangle and the Great Plains ecoregion . The site is an Important Bird Area (IBA) of Canada, designated as Last Mountain Lake NWA (SK 001) . Last Mountain Lake National Wildlife Area
156-783: A National Wildlife Area which is protected under the Canada Wildlife Act . Last Mountain Lake, also known as Long Lake, was named after a Cree oral history which recounts the Great Spirit digging out the soil and forming a valley (now known as Last Mountain Lake), and with that soil creating the hills found in the nearby area. Historically, Indigenous peoples would visit the area during the fall months to fish for northern pike and whitefish in Long Lake and hunt bison , which
234-647: A conduit for the dispersal of pollen grains, spores and seeds , the atmosphere can be considered to be a habitat-type in its own right. There are metabolically active microbes present that actively reproduce and spend their whole existence airborne, with hundreds of thousands of individual organisms estimated to be present in a cubic meter of air. The airborne microbial community may be as diverse as that found in soil or other terrestrial environments, however, these organisms are not evenly distributed, their densities varying spatially with altitude and environmental conditions. Aerobiology has not been studied much, but there
312-489: A downpour occurs and lays its eggs in the transient pools that form; the tadpoles develop with great rapidity, sometimes in as little as nine days, undergo metamorphosis , and feed voraciously before digging a burrow of their own. Other organisms cope with the drying up of their aqueous habitat in other ways. Vernal pools are ephemeral ponds that form in the rainy season and dry up afterwards. They have their specially-adapted characteristic flora, mainly consisting of annuals,
390-413: A forest is divided into parts by logging, with strips of cleared land separating woodland blocks, and the distances between the remaining fragments exceeds the distance an individual animal is able to travel, that species becomes especially vulnerable. Small populations generally lack genetic diversity and may be threatened by increased predation, increased competition, disease and unexpected catastrophe. At
468-526: A home for both static organisms, anchored to the substrate , and for a large range of organisms crawling on or burrowing into the surface. Some creatures float among the waves on the surface of the water, or raft on floating debris, others swim at a range of depths, including organisms in the demersal zone close to the seabed, and myriads of organisms drift with the currents and form the plankton . Many animals and plants have taken up residence in urban environments. They tend to be adaptable generalists and use
546-435: A lowland complex that covers just over 12% of the area. Mid-slope sites are composed of smooth blue beardtongue , bastard toadflax , early blue violet , and northern bedstraw as dominants. Mid-lower slopes contain northern rough fescue, Kentucky blue grass , and green needle grass as dominants. Lower slopes see Kentucky blue grass, northern reed grass , graceful sedge , and northern wheatgrass as dominants. Soil salinity
624-716: A mile below the ice of Antarctica; in the absence of sunlight, they must rely on organic material from elsewhere, perhaps decaying matter from glacier melt water or minerals from the underlying rock. Other bacteria can be found in abundance in the Mariana Trench , the deepest place in the ocean and on Earth; marine snow drifts down from the surface layers of the sea and accumulates in this undersea valley, providing nourishment for an extensive community of bacteria. Other microbes live in environments lacking in oxygen, and are dependent on chemical reactions other than photosynthesis . Boreholes drilled 300 m (1,000 ft) into
702-445: A mix of different habitats which are separated into three designations. The upland ecosites are mainly composed of loamy to sandy grasslands and make up about 67% of the protected area. These areas have a variety of different grasses that can grow, including wheatgrass and western porcupine grass . While these areas mainly have grasses and non-native weeds growing in the present day, they were used as agricultural land in
780-444: A natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers . Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. The protection of habitat types is a necessary step in the maintenance of biodiversity because if habitat destruction occurs,
858-410: A parasitic organism, its habitat is the particular part of the outside or inside of its host on or in which it is adapted to live. The life cycle of some parasites involves several different host species, as well as free-living life stages, sometimes within vastly different microhabitat types. One such organism is the trematode (flatworm) Microphallus turgidus , present in brackish water marshes in

#1732798760600936-557: A particular species well, but its presence or absence at any particular location depends to some extent on chance, on its dispersal abilities and its efficiency as a colonizer. Arid habitats are those where there is little available water. The most extreme arid habitats are deserts . Desert animals have a variety of adaptations to survive the dry conditions. Some frogs live in deserts, creating moist habitat types underground and hibernating while conditions are adverse. Couch's spadefoot toad ( Scaphiopus couchii ) emerges from its burrow when
1014-575: A remote breeding habitat for birds , Last Mountain Lake Wildlife Area became federally protected in 1887. The protected area originally consisted of just 1,025 hectares (2,530 acres) located on the northern end of Last Mountain Lake. It was designated Ramsar site No. 239 on May 24, 1982. In 1987, 100 years after first being protected as a bird sanctuary, the Last Mountain Lake National Wildlife Area
1092-415: A rotten log, a rock or a clump of moss ; a parasitic organism has as its habitat the body of its host , part of the host's body (such as the digestive tract), or a single cell within the host's body. Habitat types are environmental categorizations of different environments based on the characteristics of a given geographical area, particularly vegetation and climate. Thus habitat types do not refer to
1170-487: A similar way; their eggs hatch and the juvenile fish grow with great rapidity when the conditions are right, but the whole population of fish may end up as eggs in diapause in the dried up mud that was once a pond. Freshwater habitat types include rivers, streams, lakes, ponds, marshes and bogs. They can be divided into running waters (rivers, streams) and standing waters (lakes, ponds, marshes, bogs). Although some organisms are found across most of these habitat types,
1248-509: A similarly rich fauna of invertebrates as a more varied habitat. The monotypic habitat occurs in both botanical and zoological contexts. Some invasive species may create monocultural stands that prevent other species from growing there. A dominant colonization can occur from retardant chemicals exuded, nutrient monopolization, or from lack of natural controls, such as herbivores or climate, that keep them in balance with their native habitat types. The yellow starthistle, Centaurea solstitialis
1326-492: A single species but to multiple species living in the same area. For example, terrestrial habitat types include forest , steppe , grassland , semi-arid or desert . Fresh-water habitat types include marshes , streams , rivers , lakes , and ponds ; marine habitat types include salt marshes, the coast, the intertidal zone , estuaries , reefs , bays, the open sea, the sea bed, deep water and submarine vents . Habitat types may change over time. Causes of change may include
1404-498: A variety of bacteria and fungi; and snowfields on which algae grow. Whether from natural processes or the activities of man, landscapes and their associated habitat types change over time. There are the slow geomorphological changes associated with the geologic processes that cause tectonic uplift and subsidence , and the more rapid changes associated with earthquakes, landslides, storms, flooding, wildfires, coastal erosion , deforestation and changes in land use. Then there are
1482-441: A violent event (such as the eruption of a volcano , an earthquake , a tsunami , a wildfire or a change in oceanic currents); or change may occur more gradually over millennia with alterations in the climate , as ice sheets and glaciers advance and retreat, and as different weather patterns bring changes of precipitation and solar radiation . Other changes come as a direct result of human activities, such as deforestation ,
1560-423: A wide range of Brassicas and various other plant species, and it thrives in any open location with diverse plant associations. The large blue butterfly Phengaris arion is much more specific in its requirements; it is found only in chalk grassland areas, its larvae feed on Thymus species, and because of complex life cycle requirements it inhabits only areas in which Myrmica ants live. Disturbance
1638-562: Is chemosynthesis , a process by which microbes convert such substances as hydrogen sulfide or ammonia into organic molecules. These bacteria and Archaea are the primary producers in these ecosystems and support a diverse array of life. About 350 species of organism, dominated by molluscs , polychaete worms and crustaceans , had been discovered around hydrothermal vents by the end of the twentieth century, most of them being new to science and endemic to these habitat types. Besides providing locomotion opportunities for winged animals and

#17327987606001716-648: Is a conservation designation for a geographical region in Canada that restricts most human activities on that region. However, land use permits may be issued "for activities that are compatible with conservation". Such areas are established and managed by the Canadian Wildlife Service , a division of Environment and Climate Change Canada . They may consist of land and water features, as well as coastal areas extending up to 12 nautical miles (22 km) from shore. The largest national wildlife area
1794-404: Is a concept sometimes used in conservation biology , in which a single species of animal or plant is the only species of its type to be found in a specific habitat and forms a monoculture . Even though it might seem such a habitat type is impoverished in biodiversity as compared with polytypic habitat types, this is not necessarily the case. Monocultures of the exotic plant Hydrilla support
1872-516: Is a vigorous grass from Europe which has been introduced to the United States where it has become invasive. It is highly adapted to fire, producing large amounts of flammable detritus and increasing the frequency and intensity of wildfires. In areas where it has become established, it has altered the local fire regimen to such an extant that native plants cannot survive the frequent fires, allowing it to become even more dominant. A marine example
1950-433: Is also utilized by other wildlife including sharp-tailed grouse , Hungarian partridge , red fox , badgers , coyotes , white-tailed jackrabbits , and white-tailed deer . Important fish spawning areas are found within the marshes, streams, and shallow waters of the lake. These aquatic areas support approximately 18 fish species including bigmouth buffalo , which is considered a vulnerable species. Plankton are crucial in
2028-420: Is associated with the following dominant grasses: Salt grass , wild barley , and slender wheatgrass . Salt grass and Nuttals' salt-meadow grass are best supported by highly saline areas. A third complex that covers 2% of the area and that is found in wet meadows is composed of wild barley, beaked sedge , awned sedge , and spangletop. Alkaline wetlands make up a fourth complex that covers approximately 1% of
2106-494: Is evidence of nitrogen fixation in clouds , and less clear evidence of carbon cycling, both facilitated by microbial activity. There are other examples of extreme habitat types where specially adapted lifeforms exist; tar pits teeming with microbial life; naturally occurring crude oil pools inhabited by the larvae of the petroleum fly ; hot springs where the temperature may be as high as 71 °C (160 °F) and cyanobacteria create microbial mats ; cold seeps where
2184-531: Is expected to experience increased severity and frequency of extreme weather events such as droughts, flooding, and forest fires. Last Mountain Lake National Wildlife Area contains approximately 318 plant species in 58 families . Seven of these plant species are identified as rare for the Saskatchewan area. Aspen trees and willow trees are the only endemic trees in the area and are quite scarce. Shrubs are present in sufficiently moist hollows within
2262-559: Is important in the creation of biodiverse habitat types. In the absence of disturbance, a climax vegetation cover develops that prevents the establishment of other species. Wildflower meadows are sometimes created by conservationists but most of the flowering plants used are either annuals or biennials and disappear after a few years in the absence of patches of bare ground on which their seedlings can grow. Lightning strikes and toppled trees in tropical forests allow species richness to be maintained as pioneering species move in to fill
2340-665: Is located at the north end of Last Mountain Lake , 15 kilometres (9.3 mi) west of Govan . The majority of the park is in the RM of Wreford No. 280 . Last Mountain National Wildlife Area resides in territories of the Cree , Anishinabewaki, Blackfoot, and Métis . It also resides in the territory of the Assiniboine (Nakota) territory, and Saulteaux (Anishinabe) territory under Treaty 4 . The area has been designated as

With no plant life, the animals in this zone are either detritivores , reliant on food drifting down from surface layers, or they are predators, feeding on each other. Some organisms are pelagic , swimming or drifting in mid-ocean, while others are benthic, living on or near
2652-468: Is when sea urchin populations " explode " in coastal waters and destroy all the macroalgae present. What was previously a kelp forest becomes an urchin barren that may last for years and this can have a profound effect on the food chain . Removal of the sea urchins, by disease for example, can result in the seaweed returning, with an over-abundance of fast-growing kelp. Habitat destruction (also termed habitat loss and habitat reduction) occurs when

Habitat can be defined as the natural environment of an organism , the type of place in which it is natural for it to live and grow. It is similar in meaning to a biotope ; an area of uniform environmental conditions associated with a particular community of plants and animals. The chief environmental factors affecting the distribution of living organisms are temperature, humidity, climate, soil and light intensity , and

2886-467: The photic zone in the oceans are relatively familiar habitat types. However the vast bulk of the ocean is inhospitable to air-breathing humans, with scuba divers limited to the upper 50 m (160 ft) or so. The lower limit for photosynthesis is 100 to 200 m (330 to 660 ft) and below that depth the prevailing conditions include total darkness, high pressure, little oxygen (in some places), scarce food resources and extreme cold. This habitat
2964-454: The plowing of ancient grasslands, the diversion and damming of rivers, the draining of marshland and the dredging of the seabed. The introduction of alien species can have a devastating effect on native wildlife – through increased predation , through competition for resources or through the introduction of pests and diseases to which the indigenous species have no immunity. The word "habitat" has been in use since about 1755 and derives from
3042-533: The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) have satisfactory habitat within the Last Mountain Lake National Wildlife Area. These species include peregrine falcon , piping plover , whooping crane , Sprague’s pipit , ferruginous hawk , loggerhead shrike , Baird’s sparrow , Caspian tern , and Cooper’s hawk . In addition to migratory birds, the Last Mountain Lake National Wildlife Area

3276-436: The animals and plants reliant on that habitat suffer. Many countries have enacted legislation to protect their wildlife. This may take the form of the setting up of national parks, forest reserves and wildlife reserves, or it may restrict the activities of humans with the objective of benefiting wildlife. The laws may be designed to protect a particular species or group of species, or the legislation may prohibit such activities as
3354-426: The area, there are rules and regulations put in place restricting access to certain activities. Authorized activities include: Activities that are prohibited include: These regulations are put in place to protect the wildlife and plant species' habitats as well as the lives of the people who visit. Environment and Climate Change Canada 's Wildlife Enforcement Directorate (ECCC-WED) officers are put in place to ensure
3432-549: The area. Last Mountain Lake National Wildlife Area experiences a wealth of birdlife. The wide array of birdlife in the Last Mountain Lake National Wildlife Area can be attributed to it being one of the most productive lakes in southern Saskatchewan and to it being located in the heart of the Central Flyway of North America. Large populations of birds use the region’s habitats as they cross the Great Plains . During migration, more than 300 bird species have been documented in
3510-422: The area. One native grassland complex that encompasses about a tenth of the area is mainly composed of northern rough fescue and spear grass, with herbaceous species also present including holden bean , northern bedstraw , crocus Anemone, low goldenrod , yellow toadflax , and western snowberry . Degrees of alkalinity and slope determine what dominant plants are present. Moisture-tolerant species encompass
3588-567: The area. When these areas dry out, which occurs frequently, a white alkali flat ringed with red samphire , wild barley, Nuttals' salt-meadow grass, salt grass , and sea-milkwort is left behind. Sedges and reed grass make up the wetland edge vegetation, with the principal emergents being bulrush and cattail . The springs in the northern portion of the area are surrounded by raised bogs that best support cattails, sedges , and northern grass of Parnassus . The blue-green algae species Anabaena , Anacystis, and Aphanizomenon are crucial to
3666-417: The area’s aquatic food chain. There are numerous invasive species present, which are considered one of the main threats to the area. These species include smooth brome grass , Kentucky blue grass , quack grass , toadflax, nodding thistle , and sweet clover . Other main threats to the area include gravel extraction, habitat fragmentation , and other human influences. To protect the flora and fauna of
3744-400: The availability of food and the presence or absence of predators . Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior of a stem,
3822-416: The changes in habitat types brought on by alterations in farming practices, tourism, pollution, fragmentation and climate change. Loss of habitat is the single greatest threat to any species. If an island on which an endemic organism lives becomes uninhabitable for some reason, the species will become extinct . Any type of habitat surrounded by a different habitat is in a similar situation to an island. If
3900-455: The collecting of bird eggs, the hunting of animals or the removal of plants. A general law on the protection of habitat types may be more difficult to implement than a site specific requirement. A concept introduced in the United States in 1973 involves protecting the critical habitat of endangered species , and a similar concept has been incorporated into some Australian legislation. International treaties may be necessary for such objectives as
3978-408: The compliance with these regulations among all visitors to the park. The management plan not only restricts activities available to the public, it also implements restorative and conservative strategies that benefit the habitat and species of the area. Beneficial activities in the management plan include: National Wildlife Area International Associated acts A National Wildlife Area

The birds that nest in their crevices, the epiphytes that hang from their branches and the invertebrates in the leaf litter are all adversely affected and biodiversity is reduced. Habitat fragmentation can be ameliorated to some extent by
4134-491: The entire year; its levels do not vary significantly. Rainfall and snowfall rates vary throughout the year; the rainy portion of the year lasts just over six months, from April to October, with June being the rainiest month at an average of 56 millimetres of rainfall. The snowy portion of the year lasts for around six months as well, from April to October, with December being the snowiest month at an average of 60 millimetres of snowfall. Scenarios of how climate change will affect
4212-399: The flow rates of these areas. Sufficient water flow and quality can provide spawning areas for fish in creeks and streams. This Wildlife Area is now being protected but it used to be dominated by cultivated ground for crop production. Migratory birds and wildlife use the lake's shallow bays for migration routes, nesting, and roosting cover. The Canadian management plan in place has allowed
4290-745: The gaps created. Similarly, coastal habitat types can become dominated by kelp until the seabed is disturbed by a storm and the algae swept away, or shifting sediment exposes new areas for colonisation. Another cause of disturbance is when an area may be overwhelmed by an invasive introduced species which is not kept under control by natural enemies in its new habitat. Terrestrial habitat types include forests, grasslands, wetlands and deserts. Within these broad biomes are more specific habitat types with varying climate types, temperature regimes, soils, altitudes and vegetation. Many of these habitat types grade into each other and each one has its own typical communities of plants and animals. A habitat-type may suit
4368-571: The heart of the park. Several dykes were built to help control water flow and levels. Natural grasslands make up about 54% of the total protected area. The marshes and grasslands provide habitat and breeding grounds for about 280 species of migratory birds . 1,200 hectares (3,000 acres) of the park is dominated by native species . Within the park, there are trails , a picnic area, a Nature Centre, and Last Mountain Bird Observatory, Saskatchewan's only bird monitoring station. The area has
4446-720: The lichens growing in the grooves and on the raised surfaces are different from those growing on the veins of quartz. Lurking among these miniature "forests" are the microfauna , species of invertebrate , each with its own specific habitat requirements. There are numerous different microhabitat types in a wood; coniferous forest, broad-leafed forest, open woodland, scattered trees, woodland verges, clearings, and glades; tree trunk, branch, twig, bud, leaf, flower, and fruit; rough bark, smooth bark, damaged bark, rotten wood, hollow, groove, and hole; canopy, shrub layer, plant layer, leaf litter , and soil; buttress root, stump, fallen log, stem base, grass tussock, fungus, fern, and moss. The greater

The water velocity, its temperature and oxygen saturation are important factors, but in river systems, there are fast and slow sections, pools, bayous and backwaters which provide a range of habitat types. Similarly, aquatic plants can be floating, semi-submerged, submerged or grow in permanently or temporarily saturated soils besides bodies of water. Marginal plants provide important habitat for both invertebrates and vertebrates, and submerged plants provide oxygenation of
4602-521: The needs of the local residents for food, fuel and other resources. Faced with hunger and destitution, a farmer is likely to plough up a level patch of ground despite it being the last suitable habitat for an endangered species such as the San Quintin kangaroo rat , and even kill the animal as a pest. In the interests of ecotourism it is desirable that local communities are educated on the uniqueness of their flora and fauna. A monotypic habitat type

Several different trees and shrubs including trembling aspen , willow , and thorny buffaloberry also find the soil composition easy to grow in and have been able to thrive in these areas. In the lowland ecosites, which make up 33% of the protected area, saline soils and clays can be found. The composition of the soil is dependent on environmental factors such as wind, beaches , surrounding springs, and basins. Lowland ecosites can have three different compositions, dry saline soils, saline wetlands, and freshwater wetlands. Each of these composition types will have different varieties of plants found within them. Aquatic habitats (approximately 4,300 hectares (11,000 acres)) include streams , dugouts, deep marshes, and artificial reservoirs . Snow runoff and evaporation rates will affect

#17327987606004836-419: The presence or absence of all the requirements that the organism needs to sustain it. Generally speaking, animal communities are reliant on specific types of plant communities. Some plants and animals have habitat requirements which are met in a wide range of locations. The small white butterfly Pieris rapae for example is found on all the continents of the world apart from Antarctica . Its larvae feed on
4914-545: The proteins the flexibility they need. There are also unsaturated fats in their membranes which prevent them from solidifying at low temperatures. Hydrothermal vents were first discovered in the ocean depths in 1977. They result from seawater becoming heated after seeping through cracks to places where hot magma is close to the seabed. The under-water hot springs may gush forth at temperatures of over 340 °C (640 °F) and support unique communities of organisms in their immediate vicinity. The basis for this teeming life
4992-428: The provision of wildlife corridors connecting the fragments. These can be a river, ditch, strip of trees, hedgerow or even an underpass to a highway. Without the corridors, seeds cannot disperse and animals, especially small ones, cannot travel through the hostile territory, putting populations at greater risk of local extinction . Habitat disturbance can have long-lasting effects on the environment. Bromus tectorum
5070-477: The range of annual mean precipitation are predicted to be between -10% and +25%, and between -5% and +35% for the 2080s (2070-2099) Temperatures are predicted to rise between 0.5 and 3 °C for the 2020s, between 1 and 5 °C for the 2050s, and between 2 and 6.5 °C for the 2080s. Winter and spring are predicted to see the largest range of temperature increase at between 1 and 6 °C, compared to summer and fall at 1 to 4 °C. The province of Saskatchewan
5148-573: The rocky seabed have found microbial communities apparently based on the products of reactions between water and the constituents of rocks. These communities have not been studied much, but may be an important part of the global carbon cycle . Rock in mines two miles deep also harbour microbes; these live on minute traces of hydrogen produced in slow oxidizing reactions inside the rock. These metabolic reactions allow life to exist in places with no oxygen or light, an environment that had previously been thought to be devoid of life. The intertidal zone and

Their growth rates and metabolisms tend to be slow, their eyes may be very large to detect what little illumination there is, or they may be blind and rely on other sensory inputs. A number of deep sea creatures are bioluminescent ; this serves a variety of functions including predation, protection and social recognition. In general, the bodies of animals living at great depths are adapted to high pressure environments by having pressure-resistant biomolecules and small organic molecules present in their cells known as piezolytes , which give

Animals adapted to these extreme habitat types also exist; fairy shrimps can lay "winter eggs" which are resistant to desiccation , sometimes being blown about with the dust, ending up in new depressions in the ground. These can survive in a dormant state for as long as fifteen years. Some killifish behave in
5382-531: The setting up of marine reserves. Another international agreement, the Convention on the Conservation of Migratory Species of Wild Animals , protects animals that migrate across the globe and need protection in more than one country. Even where legislation protects the environment, a lack of enforcement often prevents effective protection. However, the protection of habitat types needs to take into account
5460-535: The southeastern United States. Its first intermediate host is a snail and the second, a glass shrimp . The final host is the waterfowl or mammal that consumes the shrimp. Although the vast majority of life on Earth lives in mesophyllic (moderate) environments, a few organisms, most of them microbes , have managed to colonise extreme environments that are unsuitable for more complex life forms. There are bacteria , for example, living in Lake Whillans , half
5538-559: The structural diversity in the wood, the greater the number of microhabitat types that will be present. A range of tree species with individual specimens of varying sizes and ages, and a range of features such as streams, level areas, slopes, tracks, clearings, and felled areas will provide suitable conditions for an enormous number of biodiverse plants and animals. For example, in Britain it has been estimated that various types of rotting wood are home to over 1700 species of invertebrate. For
5616-473: The survival and reproduction of a particular species . A species habitat can be seen as the physical manifestation of its ecological niche . Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil , moisture , range of temperature , and light intensity . Biotic factors include
