1 Characteristics of Species Prone to Extinction

2 Amphibians 38% of US amphibian species in decline Reasons: 1. Habitat Loss 2. Pollution 3. Disease

3 Bird Statistics 9,800 known bird species 70% are declining in number

4 10 Most Threatened Bird Species Ivory-billed woodpecker California Condor Whooping Crane Gunnison Sage-Grouse Kirtland’s Warbler Piping Plover Florida Scrub-Jay Ashy Storm-Petrel Golden-cheeked Warbler Kittlitz’s Murrelet

5 Bird Migratory Routes National Refuges help to protect wetlands along bird migration routes

6 Causes of Endangerment

7 Habitat Loss #1 Cause

8 Habitat Loss Common problem: habitat fragmentation

9 Habitat Loss

10 Habitat Degradation - Pollution

11 Invasive Species

12 Group 1 – Chinese Privet & Snakes in Florida Group 2 – Wisteria & Wild Boar Group 3 – Tamarsik & Grey Squirrel (in Europe) Plants: Chinese Privet / Japanese kudzu / Chinese Wisteria / Bamboo / Hydrilla / Eurasian Milfoil / Mimosa / Animals: grey squirrel in England / snakes in Florida / Wild Boar / Snake Fish / carp

13 Role of Introduced Species Accidental Food crops Livestock Control Pests Pets Game - Hunting Ornamental

14 Modes of Transmission Stowaways on aircraft In the ballast water of tankers Hitchhikers on imported products Asian Carp http://www.youtube.com/watch?v=yS7z kTnQVaM http://www.youtube.com/watch?v=yS7z kTnQVaM

22 Sale of Exotics

23 Predator Control & Pest Control

24 Primary Root of all Causes of Endangerment Rising Population Growth Rising Resource Use No Environmental Economic Accounting Poverty
