Ch9 New Protected Areas Flashcards
How do the species and community approaches to conservation differ?
-What is the initial goal, protecting single species or whole community?
What criteria are used to pick species or communities as a priority for preservation?
Identify species/ communities that are priorities for conservation (Distinctiveness)
-Find areas that allow us to meet these conservation goals
-Link new areas to existing protected areas to expand/ establish conservation networks
-Distinction, utility value (ecotourism), Conservation status.
Which conservation approach is used for US policy?
-ESA (protects species)
Which conservation approach would be more effective?
Community approach
What is a big drawback to the species-approach to conservation?
Public backlash, public perception that a “worthless species” is holding up progress.
What makes an area a biodiversity Hot Spot?
Key areas in the world that have high species richness, endemism, and risk of extinction.
How can targeting hot spots help us reduce the opportunity cost of conservation?
With the same amount of land inside and outside of a hot spot, the hot spot is more bang for your buck in terms of conservation, as the conservation efforts are utilized more efficiently.
Where are the hotspots in the US?
California, Hawaii, etc.
What is GAP analysis?
mapping data layers depicting both location and conservation status of protected areas, and species ranges. What areas should we think about protecting?
What are the principles GAP analysis as a conservation tool.
-Prevention: Cheaper and more effective to save species while they are still common
-Find areas that represent gaps in our reserve network by comparing distribution data of
species diversity, endangered species, reserve boundaries, etc.
How is GAP analysis done?
Establish 3 data layers:
Vegetation Land Cover
-Known or estimated vertebrate species distributions
-Land Stewardship (ownership)(Private, public reserve, etc).
Is GAP analysis a reactive or proactive approach to conservation?
Proactive
