1 Species at RiskTwo Rivers Wildlife Park invites you to learn more about species at risk in Nova Scotia…
2 What are Species at Risk? Any animal, plant, or other organism that is considered at serious risk of extinctionS P E C I E S A T R I S KUsually species are at risk due to human activitiesExtinction is occurring at a rate never before seen in the history of human existence
3 What are the Species at Risk Categories 1. Endangered - a species facing imminent extirpation or extinctionThreatenedSpecial Concern (Vulnerable)Endangered2. Threatened - a species likely to become endangered if limiting factors are not reversed3. Special Concern (Vulnerable) - a species sensitive to human activities or natural events. This sensitivity makes it vulnerable to harm.Vocabulary:Extirpation: Loss of a species from a specific area but one or more populations surviving elsewhere on Earth.Extinction: Species no longer in existence
4 Species at Risk Around the World 11,000 species face extinction800 extinct due to human activitiesExtinction is occurring at a higher rate than ever before
5 How many Species at Risk ? 431 species at risk in CanadaOver 40 species at risk in NS12 species extinct in Canada5 species extinct in NS

7 Why Are Species at Risk?Usually species are at risk of extinction due to human activities4 Main Reasons:Habitat lossOver exploitation (i.e. over-hunting)PollutionExotic (alien) species
8 Habitat Loss Habitat loss is the main threat to species. Our need for more and more land for buildings, farming, forestry and roads sometimes leaves wildlife without a place to live.Without a place to live a species becomes extinct.
9 Over-ExploitationAnother major cause of extinction is too much hunting, fishing, or trapping, called over-harvesting.The Atlantic cod was over-harvested, or fished to the point of being endangered.
10 Alien SpeciesAlien species are plants or animals that are introduced to an area by humans, either accidentally or on purpose. The alien species may take over and kill native species by out-competing them for food or habitat.Purple loosestrife, a plant originally from Europe and Asia is now found across Canada.It clogs habitats, and is a threat to some species who live in these habitats.This is not only bad news for certain species, but also for the humans who rely on these native species.
11 PollutionToxic chemicals are finding their way into more and more water habitats.Toxic chemicals do not only affect water. Acids, metals, and other poisonous compounds rain down on land habitats too, often thousands of miles from their source.
12 Why is Wildlife Important Everything we have or use as human beings has its roots in nature, and most of these in wildlife.In fact, without wildlife, the planet could not support human life.
13 Saving WildlifeSaving a species that is at risk of extinction involves several steps:1. Getting them put on the species at risk list2. Passing laws to protect the remaining wildlife and habitat3. Organize recovery of the species
14 Two Rivers Wildlife Park During your visit to Two Rivers Wildlife Park you can learn more about some species that are at risk in Nova Scotia.Did you know that Two Rivers helps injured or abandoned animals? The park has a rehabilitation program to help these animals.The next few slides will introduce you to some of the animals at Two Rivers that are considered at risk in NS
15 American MartenThe Marten is considered at risk in Nova Scotia. You can see this member of the weasel family atTwo Rivers Wildlife Park.Martens almost became extinct in NS because of over-hunting. With loss of suitable habitat, it is likely that there are less than 50 animals on Cape Breton Island.
16 MooseThe moose is the largest member of the deer family. Found throughout NS, moose are only considered at risk on the mainland. There is a healthy population on Cape Breton Island.Millie the moose was found injured and abandoned in She was successfully rehabilitated at Two Rivers! Visit Two Rivers Wildlife Park to learn more about moose!
17 LynxLynx were once found all over NS, but today they are mainly found in the Cape Breton Highlands. They are a species at risk because of loss of habitat, human pressures, and competition from other animals.You can learn more about this wild cat during your visit to Two Rivers Wildlife Park.
18 To Learn More about Species at Risk: We hope you enjoyed this presentation about Species at Risk. To better understand why species are at risk and what you can do to help, complete some of the Two Rivers EduKit activities and visit Two Rivers Wildlife Park.Graphics and information courtesy of :Eaton, Samara T and Boates, J.
