Title: Conservation and Biodiversity


1
Chapter 5
  • Section 2
  • Conservation and BiodiversityMethods to protect
    endangered species.

2
Conservation biology The study and use of
strategies to protect biodiversity.
3
Conservation biology involves conservation of
species and the natural resources that are
necessary for living things (sun, water, air,
soil, plants, animals).
4
Conservation Strategies
  • Legal protection
  • Habitat preservation
  • Habitat corridors
  • Sustainable use
  • Reintroduction programs
  • Captivity

5
Legal Protection
  • U.S. Endangered Species Act made it illegal to
    harm species on the endangered or threatened
    species list
  • Convention on International Trade in Endangered
    Species prohibits world wide trade of listed
    species

6
Preserving Habitats
  • State and national parks preserve natural
    environments and provide protected habitats for
    many organisms.

7
Habitat Corridors
  • Protected strips of land that connect two
    wilderness areas.
  • Provide path for migration.
  • Prevent habitat fragmentation

8
Sustainable Use
  • Using natural resourses in such a way as to limit
    or prevent adverse impacts on plant and animal
    species.

9
Sustainable Use
  • Brazil nuts are harvested in a way that protects
    the Amazon but provides income to people who live
    in the region

10
Captivity
  • Species that can no longer survive in the wild
    due to changes in their habitat can be raised by
    people.

11
Reintroduction Program
  • Captive species can be reintroduced into the wild
    once their habitat is reestablished.

12
Reintroduction of animals into the wild can be
difficult because animals may loose the behaviors
necessary to survive in the wild while in
captivity.
