Conservation Biology Midterm-Threats To Biodiversity 2

Front 1

species (as defined legally for the ESA)

Back 1

biological species as we know it plus subspecies plus any distinct population segment (thats why we can have different runs of salmon protected)

Front 2

distinct population segment (as redefined in 1997)

Back 2

discreet from other populations, significant to the species as a whole

Front 3

Intrinsic value

Back 3

is an ethereal concept that is difficult to impossible to define which makes it a difficult concept to use when furthering the case of conservation -one tack is to establish that humans are part of the biotic system and once that can be accepted the biome is valuable because we are part of it

Front 4

economic factors came into play in 1982

Back 4

when endangered species committee was designated (“god squad”) to determine if social concerns out weigh concerns to species

Front 5

delisting process

Back 5

initiated by any concerned party, determined by secretary, determined by objective criteria laid out in recovery plan

Front 6

other tools for conservation

Back 6

CITES

Front 7

CITES

Back 7

(international agreement) convention on international trade of endangered species implemented mid 1970’s, purpose to regulate trade of endangered species, 3 lists, 1- bans any trade, 2- allows trade accompanied by permit, 3 -any country can put a species on a list if they are worried about that spp in their country but it isn’t globally threatened

Front 8

ESA listing process

Back 8

any citizen may propose that a spp be listed as threatened or endangered, Secretary of Interior decides whether to pursue case based on evidence, 1. loss of habitat 2. overutilization 3. disease or predation 4. inadequacy of existing regulatory mechanisms 5. other natural or manmade factors that may threaten species or habitat

Front 9

Secretary makes ESA determination based solely on
