What kind of animals in grasslands




















However, both the Sumatran tiger Panthera tigris sumatrae and the Malayan tiger Panthera tigris jacksoni are endangered species. Habitat destruction and poaching have whittled their combined population to less than individuals. Black-footed ferrets Mustela nigripes came back from the brink of extinction 30 years ago and are the only ferret species native to North America. Each of the big three large, flightless birds -- the ostrich, the rhea and the emu -- live in grassland habitats.

These powerful, fast runners inhabit the dry savanna grasslands throughout Africa. Small grassland birds such as grouses, meadowlarks, pipits, finches, quails, sparrows and plovers consume an abundance of seeds, berries and insects. Insects abound in grasslands. Grasslands habitats encompass bumble bees, crickets, butterflies, locusts, grasshoppers and beetles. Prairie mole crickets Gryllotalpa major are the largest mole crickets in North America and can grow up to 2 inches long.

An area that receives very little rain becomes a desert; an area that receives significant amounts of rain often develops into forest. Grasslands hang somewhere in the balance. They receive 50 to centimetres during the rainy season 6 to 8 months , and endure drought for the remainder of the year. Plant and animal species vary greatly across the Savannah, curbed by differences in climate, but much of the Savannah is characterized by thin soil where only grasses and flowering plants can grow.

Temperate Grasslands , which include Canadian grassland ecosystems, are also found around the globe. Plant and animal species in temperate grasslands are shaped by less rainfall 25 to 90 centimetres , and cycle through a greater range of seasonal temperatures. Many temperate grassland animals, which must adapt to dry, windy conditions, are recognizable to Canadians: grazing species like antelope and elk; burrowing animals like prairie dogs and badgers; and predators like snakes and coyotes.

Grasslands National Park, for example, boasts glacial meltwater channels that feature plateaus, coulees, buttes that rise abruptly at the horizon, and layers of rock formation that hold fossilized secrets from 80 million years ago. Significant parts of it are formally protected, as in the case of Grasslands National Park, Saskatchewan. Mammals, insects, birds, reptiles, and plants all co-exist in a balance that astonishes the imagination.

Not only are black-tailed prairie dogs an important food staple for a variery of predators, but their abandoned burrows shelter many grassland species, including the endangered burrowing owl and black-footed ferret.

Two hundred years ago, anywhere from 30 to 70 million bison roamed across North America, grazing on native grasses and providing food, clothing, and even shelter for Plains Indians, who built their teepees from buffalo hide.

Within the span of a few decades late in the 19th-Century, habitat loss and European trophy hunters drove bison to the edge of extinction. To learn more, visit the bison fact sheet.

The pronghorn antelope can run up to kilometers an hour and is one of the fastest mammals in the world, second only to the cheetah. This speed reveals it as a true master of the North American grassland—the only place in the world where it exists, giving us another important reason to preserve this habitat.

The exquisitely cute black-footed ferret, which relies almost exclusively on the black-tailed prairie dog for food and shelter, is the only ferret species indigenous to North America—and it was very nearly lost to us forever. From the Wyoming colony, captive populations were gradually developed in facilities across North America. In , the first 34 black-footed ferrets to live on the Canadian prairies in 70 years were released into the wild at Grasslands National Park. Visit the black-footed ferret fact sheet to learn more.

Swift foxes are a clear example of the unique adaptations undergone by grassland species to suit their habitat: unlike nearly every other fox species, swift foxes use dens throughout the entire year—both as a place to raise their young, and as shelter from predators in a landscape with few other places to hide.

Swift foxes have been clocked at more than 60 kilometers per hour, a speed which helps them reach shelter quickly in moments of danger.

Swift foxes vanished from the Canadian prairies during the 20th-century, mostly due to over-hunting coupled with severe winters and droughts. Visit the swift fox fact sheet to learn more. The prairie rattlesnake, whose name comes from rings on its tail which knock together when agitated, is the only venomous snake on the Canadian prairies.

Using its tongue as a smell- and heat-sensing membrane, it can detect prey mostly small mammals and amphibians from 30 meters away.

The burrowing owl, a small, sturdy bird which, unlike most other owl species, nests in abandoned underground burrows and mimics the hiss of a rattlesnake for protection, is one of the most endangered birds in western Canada. To learn more, visit the burrowing owl fact sheet. Their extremely long, down-curved bill is well adapted to a prairie diet of invertebrates, such as grasshoppers and earthworms.

This striking grassland insect relies on the branched umbrella-plant both as a critical food source and as a host for laying eggs. There are two known populations of this butterfly in Canada.

The southern mountain population, found only in the southern interior of British Columbia, is an endangered species, with only about individuals remaining. The prairie population, listed as a threatened species, has not been thoroughly studied, though researchers estimate that anywhere from to individuals remain.

Not only is it one of the most palatable grasses available to grazing animals, it is also a small but mighty element in grassland restoration. Considered one of the most drought-resistant grassland species, it has been used to re-vegetate disturbed or dry parts of the central Great Plains.

Threats include urban and agricultural development, expanding forests, and invasive species which crowd out native grassland plants. At the heart of each threat are the greatest dangers for grassland species: the destruction, degradation, and fragmentation of grassland habitat.

Expanding towns and cities in the Canadian prairies compromise grassland habitat, particularly because many species, like the threatened Ferruginous hawk, will abandon wild areas that are too close to human settlement.

Agriculture can destroy or limit grassland biodiversity. Pesticide use and the planting of food crops are especially potent threats to native grasses.

Once the grassland is broken by the plough, the protective grass, moss and lichen groundcover disappears, leaving fertile soil vulnerable to the strong prairie wind. As a result, restoring a grassland habitat that has been developed for agriculture is a long, difficult process that requires resilient plant species and a nearby renewable seed source. Overgrazing means repeated, heavy foraging, which continues year after year until the native plant community is severely depleted and the soil begins to erode.

Today, ranchers recognize this danger and are generally careful to rotate their livestock across different grazing sites, giving native plants the time and shelter to recover.

Historically, hunting and poaching have also significantly disrupted grassland ecosystems. As a result, predators who relied on those species lost a crucial food source and began disappearing, as well.

The domino effect of this widespread disturbance to the natural food web is still widely felt today, despite reintroduction efforts and strict hunting policies. Grasslands are increasingly threatened by areas where trees have managed to take root and grow. There are both human and natural causes for this phenomenon, which reduces important grassland surface area.

Livestock grazing, for example, can disturb the healthy grass systems, compromising plants and offering opportunities for trees to germinate. Wildfires are also an issue. Ignited naturally by a lightning strike or artificially by humans, fires add valuable nutrients to grassland soil and help chase back encroaching forests. Over the past seventy years, far fewer grassland fires have resulted in more opportunity for forests to expand into grassland territory; grazing is also a possible cause for this issue, because over-grazed grassland provides very little fuel to burn and prevents important fires from spreading as they otherwise would.

A significant threat to remaining grassland ecosystems is the widespread introduction of non-native plants, which often have no natural predators to reduce their population and can out-compete native plants for moisture and nutrients. Relatively recent trends in grassland recreation, such as camping, hiking, and motorized vehicles, also contribute to the inadvertent spread of invasive seeds.

Across the country, in all strata of society—from ranchers to campers to government officials—Canadians have a far better understanding today than ever before of the need for balance between human activity and fragile ecosystems. Often, a black-and-white solution to some of the greatest problems facing grassland ecosystems is simply unrealistic, and scientists must constantly experiment and adapt in order to tweak conservation strategies. Other approaches to grassland conservation involve prescribed fires, which, under very specific circumstances and within set boundaries, remove tree encroachment, enrich the soil, and improve conditions for grazing wildlife.

Though prescribed fire has a long history in grasslands, including First Nations people who used fire to improve berry crops and 19th-century ranchers seeking to enlarge their grazing pasture, the effect is not yet entirely understood. The reintroduction of nearly extinct species, like the bison and the black-footed ferret, has also made small inroads into the gradual restoration of grassland biodiversity. In the case of the black-footed ferret, the first kits to be born in the wild in seventy years were observed in the summer of , a significant achievement for this species that had all but vanished from the world just a short time ago.

Species at Risk Public Registry. All rights reserved. The Northern Leopard Frog Lithobates pipiens is named for its leopard-like spots across its back and sides.

Historically, these frogs were harvested for food frog legs and are still used today for dissection practice in biology class. Northern Leopard Frogs are about the size of a plum, ranging from 7 to 12 centimetres.

They have a variety of unique colour morphs, or genetic colour variations. They can be different shades of green and brown with rounded black spots across its back and legs and can even appear with no spots at all known as a burnsi morph. They have white bellies and two light coloured dorsal back ridges.

Another pale line travels underneath the nostril, eye and tympanum, ending at the shoulder. The tympanum is an external hearing structure just behind and below the eye that looks like a small disk. Black pupils and golden irises make up their eyes.

They are often confused with Pickerel Frogs Lithobates palustris ; whose spots are more squared then rounded and have a yellowish underbelly.

Male frogs are typically smaller than the females. Their average life span is two to four years in the wild, but up to nine years in captivity. Tadpoles are dark brown with tan tails. Lampreys are an amazing group of ancient fish species which first appeared around million years ago. This means they evolved millions of years before the dinosaurs roamed the earth.

There are about 39 species of lamprey currently described plus some additional landlocked populations and varieties. In general, lamprey are one of three different life history types and are a combination of non-parasitic and parasitic species. Non-parasitic lamprey feed on organic material and detritus in the water column.

Parasitic lamprey attach to other fish species to feed on their blood and tissues. Most, 22 of the 39 species, are non-parasitic and spend their entire lives in freshwater. The remainder are either parasitic spending their whole life in freshwater or, parasitic and anadromous. Anadromous parasitic lampreys grow in freshwater before migrating to the sea where they feed parasitically and then migrate back to freshwater to spawn.

The Cowichan Lake lamprey Entosphenus macrostomus is a freshwater parasitic lamprey species. It has a worm or eel-like shape with two distinct dorsal fins and a small tail. It is a slender fish reaching a maximum length of about mm. When they are getting ready to spawn they shrink in length and their dorsal fins overlap. Unlike many other fish species, when lampreys are getting ready to spawn you can tell the difference between males and females.

Females develop fleshy folds on either side of their cloaca and an upturned tail. The males have a downturned tail and no fleshy folds. These seven gill pores are located one after another behind the eye.

There are several characteristics which are normally used to identify lamprey. Many of these are based on morphometrics or measurements, of or between various body parts like width of the eye or, distance between the eye and the snout. Other identifying characteristics include body colour and the number and type of teeth. Some distinguishing characteristics of this species are the large mouth, called and oral disc and a large eye. This species also has unique dentition.

For example, these teeth are called inner laterals. Each lateral tooth has cusps and together they always occur in a cusp pattern.

At the same time, the Sea Otter is the largest member of its family, the mustelids, which includes River Otters, weasels, badgers, wolverines and martens. It may come to land to flee from predators if needed, but the rest of its time is spent in the ocean.

It varies in colour from rust to black. Unlike seals and sea lions, the Sea Otter has little body fat to help it survive in the cold ocean water. Instead, it has both guard hairs and a warm undercoat that trap bubbles of air to help insulate it.

The otter is often seen at the surface grooming; in fact, it is pushing air to the roots of its fur. They can also forage for worms and shrimp in wetlands or mudflats outside of their breeding season. Though they are known as shorebirds, they must breed in areas with sparse, short grasses and mixed-grass prairies.

Original and proud in every way, they strut around their open terrain, bobbing their head with bouncy steps. African elephants know how to stand out. They are the largest land mammals on the face of the Earth.

Though the males can weigh up to 6 tonnes , elephant families have a matriarchal head. Additionally, African elephants can be incredibly sociable and helpful giants. In fact, they are known as a keystone species, specifically, ecosystem engineers.

The elephants use their tusks to dig up dry riverbeds and create waterholes, break small trees and bushes to maintain grasslands, and spread plant seeds while keeping the soil healthy.

They can be found roaming the savannas of sub-Saharan Africa for roots, grasses, fruit, and bark to feed on. Ferrets are cute, but they mean business. They inhabit temperate grasslands in North America where they can hunt their major food source: prairie dogs. Sure enough, they blend in well with grassland soils and plants.

More active at dawn and at dusk, they can sleep up to 21 hours per day. They wake up at night to hunt, eat, and tend to their offspring, which are called kits. These black-footed ferrets usually produce furry kits in litters of Though kits are born blind and dependent on the protection of their underground homes, at about 90 days of age, kits are trained to go on hunting ventures.

They are hungry herbivores who travel regularly! In fact, they will migrate up to 2, kilometers for food , mostly red oat grass. Plains zebras graze two-thirds of the day on a variety of grasses.

Native to over 15 African countries, they can be found traversing savannas in small families known as harems. These are usually made up of a male or stallion, several females, and their offspring. There is also no question that they are sociable and protective of another.

Though plains zebras may travel in large herds, they are known to keep close with their biological family members.

As the foal and female zebras run, the males follow behind them, ready to defend their family from any predators. The graceful and observant pronghorn antelope is the fastest hoofed animal in North America, capable of reaching speeds up to 60 miles an hour. Not only do grasslands provide them with free, open land for running, but they offer these herbivores key ingredients for their diet: sage, forbs, and other prairie plants.

Female pronghorns also rely on the vegetation of grasslands to hide their offspring so that they can forage while their young are safe. Often, pronghorn mothers keep within 2 miles of them. However, do not underestimate these youthful pronghorns. In a matter of days after their birth, the small pronghorns can travel, forage, and outrun a human being. Thankfully, grasslands provide a sweet space for the fawns to play!

They can be found in the steppes of Mongolia, China, and Kazakhstan. The steppes of Mongolia are a great site for their diet which largely relies on grass and other shrubby vegetation.

In fact, these steppes may be the largest area of unaltered grasslands in the world.
