33. Conservation Biology The study of methods to protect biodiversity.
1973 – President Nixon signed the U.S. Endangered Species Act
The Act made it illegal to harm endangered/threatened species and their habitats.

34. Conservation Biology Create nature preserves
Sustainable use – humans can use the resources as long as it doesn’t harm the ecosystem.
Example – Areas where trees are harvested are replanted with young trees.
Create Habitat corridors.

35. Habitat Fragmentation & Habitat Corridors

36. Habitat Corridor

37. Reintroduction Programs
Reintroduce organism into an area where they once lived.
The factors causing the decline of the organism must be removed or fixed.

38. Reintroduction Programs – Black Footed Ferret

39. Reintroduction Programs

40. Endangered Species – California Condor

41. Captivity Humans raise animals to reintroduce them later.
May be kept in captivity if they are the last of their species.
