Conservation Biology

In-Situ Conservation

• “In the field” conservation

• Done by protecting them in their habitat.

Ex-Situ Conservation

• “Out of the field” when few individs left

• Conserving/ helping the population

repopulate in a lab, zoo, aquarium.

Bald Eagle Conservation

• 1963= 417 nesting pairs

• Loss of habitat, hunted, DDT

• Ex-Situ rehab.

• Aug 8, 07: off End Species List!

Seed Banks

• Ex-Situ: Saves plants from destruction

• Cryogenically frozen for future

• Stored in duplicate locations

Botanical Gardens

• Ex-Situ: Breed plants and educate

Aquariums: Ex-Situ

• Grow corals

• Rehab injured animals

• Raising public awareness

Zoos: Ex-Situ

• 1973 -illegal to import or trade products of E.S.

unless used for science (USFWS)

• Species on list cannot be “taken”, threatened,

killed, harmed: habitat can’t be harmed

• Decision must be made on biological basis

– Must develop a recovery plan

– 1350 species listed (4000 candidates)

Problems w/ ESA• Encourages people to

destroy land before

listing

• No focus on ecosystem

• Is inflexible and

political

• Focus on charismatic

megafauna

• Only 8 species de

listed

International Laws

• CITES - Convention on the International

Trade of Endangered Species

• Japan/Finland/Iceland no sign!

Marine Mammal Protection Act

and CITES.

Support $$ env. organizations.

How to Save End. Species
