Saving Habitat – Pt. 2:
Legal Aids to Habitat Conservation
![Page 2: Saving Habitat – Pt. 2:](https://reader035.vdocuments.site/reader035/viewer/2022062310/568161c2550346895dd1a89c/html5/thumbnails/2.jpg)
Ideal Design for Nature Reserves
• Importance of Connectivity between preserves

3 Functions of Biosphere Reserves:
• Conservation: landscapes, ecosystems, species and genetic variation
• Development: economic and human and culturally adapted
• Logistic support: research, monitoring, environmental education and training

What have we done in the U. S. to preserve Biological Diversity?
• 28% of land area is Federally managed, mostly in the West & Alaska
• 4% of land area = in Wilderness (106 million acres), >50% in AK
• plus millions of acres of less-protected land in National & State Parks, Wildlife Refuges, etc.

What have we done in the U. S. to preserve Biological Diversity?
• National Parks are a unique idea in the world - first parks were in US
• Most were set aside for scenic beauty, not as species reserves

…but how well do parks do in preservation of biodiversity?
from: Newmark 1995; "Extinction of Mammals in National Parks"

Beyond National Parks, several other US Agencies charged with land & species
preservation
• Dept. of Agriculture• Dept. of Commerce (!)• Dept. of Interior (several agencies)• EPA

The Big Question -
• Do we manage for preservation of…– Species? – OR– Habitats?
• What would be better???
![Page 12: Saving Habitat – Pt. 2:](https://reader035.vdocuments.site/reader035/viewer/2022062310/568161c2550346895dd1a89c/html5/thumbnails/12.jpg)
What is the main Legislation we have available for biodiversity preservation?
• Endangered Species Act (ESA) (1973)– Conservation of threatened & endangered species– Prohibits “taking” of listed species or harming habitat
• National Environmental Policy Act (NEPA) (1969)– Gov’t must give consideration to environment – Requires EA’s & EIS’s
• Clean Water Act (1972)– Pollution control– Preserve wetlands, mitigate loss
• Clean Air Act (1970)– Pollution control
![Page 13: Saving Habitat – Pt. 2:](https://reader035.vdocuments.site/reader035/viewer/2022062310/568161c2550346895dd1a89c/html5/thumbnails/13.jpg)
For Biodiversity, ESA is main legislation
• Based on the HCN article you read – “Bred for Success” – how well are we doing?
• In groups, discuss:– Benefits of ESA– Problems of ESA
• Related to preserving species & their habitats
