Two Rivers Wildlife Park invites you to learn more about species at risk in Nova Scotia…

What are Species at Risk?What are Species at Risk?

S P E C I E S A T R I S K

Any animal, plant, or other organism that is considered at serious risk of extinction

Usually species are at risk due to human activities

Extinction is occurring at a rate never before seen in the history of human existence

What are the Species at Risk What are the Species at Risk CategoriesCategories

1. Endangered1. Endangered - a species facing imminent extirpation or extinction

3.3. Special Concern (Vulnerable) Special Concern (Vulnerable) - a species sensitive to human activities or natural events. This sensitivity makes it vulnerable to harm.

2. ThreatenedThreatened - a species likely to become endangered if limiting factors are not reversed

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

Why Are Species at Risk?Why Are Species at Risk?

Usually species are at risk of extinction due to human activities

4 Main Reasons: Habitat loss Over exploitation (i.e. over-hunting) Pollution Exotic (alien) species

Habitat Loss

Without a place to live a species becomes extinct.

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.

Over-Exploitation

The Atlantic cod was over-harvested, or fished to the point of being endangered.

Another major cause of extinction is too much hunting, fishing, or trapping, called over-harvesting.

Alien Species Alien 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.

This is not only bad news for certain species, but also for the humans who rely on these native species.

It clogs habitats, and is a threat to some species who live in these habitats.

Pollution

Toxic 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.

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.

Saving WildlifeSaving a species that is at risk of extinction involves several steps:

2. Passing laws to protect the remaining wildlife and habitat

1. Getting them put on the species at risk list

3. Organize recovery of the species

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

American Marten The Marten is considered at risk in Nova

Scotia. You can see this member of the weasel family at

Two 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.

Moose

Millie the moose was found injured and abandoned in 2005. She was successfully rehabilitated at Two Rivers! Visit Two Rivers Wildlife Park to learn more about moose!

The 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.

Lynx Lynx 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.
