Ch 9 Flashcards
(50 cards)
protected areas
best way to preserve diversity
established by gov agencies, NGOs, conservation societies
goals
preservation of biology
scenic beauty
to protect water shed/resources
protected levels
strict nature reserves
national parks
national lakeshore/seashore
partial protection levels
managed resource areas
national forest land
protection levels
most protected
I, II, III, IV
managed for resources
V, VI
how much is protected
about 16% of earths land surface
<5% ocean
IUCN Green list
effective governance, design, and management
successful at conserving biodiversity
respect for the local community
contributes to climate change response
establishes how the parks are running
marine protected areas
harder to protect
boundaries are difficult to establish
less self-contained recruitment may depend on larvae from other regions
harder to control pollution, sources can diffuse and be harder to pinpoint/stop
high seas treaty
agreement under UN Convention on the Law of the Sea on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction
new protected areas
mechanism to share genetic resources
funding mechanism and framework
how have fishing efforts changed
people fish just outside of the boundaries more often than other areas
establishing new protected areas
identify species/communities that are priorities for conservation
find all areas that allow us to meet these conservation goals
link new areas to existing protected areas to expand/establish conservation networks
identify priorities
distinctiveness
endangerment
utility value
distinctiveness
community of rare endemic species, more distinct than one that is widespread and common
taxonomic distinction, relic species that are unique, or the sole representative of their genus, family
endangerment
what are the conservation categories on the IUCN red list
utility value
those with some present or future value to humans have higher priorities
species conservation approaches
ESA protects species
indicator species
protection of a species could preserve an entire community it represents
flagship species
one with high existence value will bring in tourist dollars
public backlash
public perceptions that a “worthless species” is holding up progress
biodiversity hot spot approach
key areas in the world have high species richness, endemism, and risk of extinction
attempt to maximize preservation even if a small amount of area is preserved
ecosystem and community approaches
costs
economic value
functionality
costs
is it more cost effective to concentrate on communities?
cheaper to preserve a habitat before they are endangered?
economic value of communities
communities have economic value
water sheds
functionality
changes made in an ecosystem
may make it difficult to conserve a single species or population
