What does it mean to be “At Risk?”
A species is classified as a species at risk when its population is very small or declining and it may disappear if it is not protected. Scientists use different categories to describe how close a species is to extinction. A threatened species is one that could become endangered in the near future if no action is taken, while an endangered species is already in serious danger of becoming extinct. Categorizing species in this way is important because it helps scientists, governments, and conservation groups decide which species need the most protection and what actions should be taken to help them survive.
What does it mean to be “Endangered?”
Species can become endangered for many reasons. One major cause is habitat loss, which happens when natural areas like forests, grasslands, and wetlands are destroyed to make room for farming, roads, or cities. Pollution is another cause, as chemicals and waste can harm or kill plants and animals. Overhunting and overfishing also contribute to endangerment when animals are taken faster than they can reproduce. Human activities play a large role in species endangerment by damaging habitats, polluting land and water, introducing invasive species, and contributing to climate change.
In Saskatchewan, there are several species that are considered at risk.
Human causes
Species endangerment is often caused by human activities that harm the natural environment. One major cause is habitat loss which occurs when forests, grasslands, and wetlands are destroyed to make space for farming, roads, or cities. Pollution also plays a significant role: chemicals and waste can poison plants and animals and damage ecosystems. Overhunting and overfishing also threaten many species because animals are taken faster than they can reproduce.
Local Examples
In Saskatchewan, examples of include the Plains Bison, the Burrowing Owl, and the Greater Sage-Grouse. The Plains Bison plays an important role in Canadian ecosystems, especially in grasslands. By grazing, bison help prevent grasses from becoming overgrown and allow many plant species to thrive. Their movement across the land also helps spread seeds and creates habitats for other animals, making them a key species in maintaining healthy ecosystems.
What can I do?
Individuals and communities can help protect species at risk in many ways. One important action is protecting natural habitats and reducing pollution so wildlife has safe places to live. People can also support conservation programs, follow wildlife protection laws, and educate others about the importance of protecting endangered species.
Climate change has a strong impact on species at risk in Canada because it changes habitats, food sources, and migration patterns. Many species struggle to adapt quickly to these changes, which increases their risk of extinction. It is important to protect species even if they are not directly useful to humans because every species has a role in the ecosystem. Species diversity is essential for ecosystem health, as a wide variety of plants and animals helps keep ecosystems balanced and resilient to change.
