endangered species Flashcards
what is biodiverisity
the variety of life forms found on earth, habitat or ecosys
what is extinction
the elemination of a speices from all areas
extirpation
when a species is eliminated from its native area but is found in another area
possibly caused by a shift in its realized niche (composition of habitat alteration)
endangered
speices that are threatened with extirption or extinction
threatened
a species that will become endangered if preventative measure are not taken
special concern species
species that may become threatened or endangered bc of threats to their habitat or themselves
what is the extinction trend
steady increase (now up to 841 in CAN)
what causes extinction or extir
over-harvesting
predator control (alterations to the keystone species or introduction of invasive species)
habitat alterations (may involve destruction, fragmentation or thermal effects imposed by climate change)
what is CITES
an international agreement to protect threatened species from international trade
what is the IUCN
a body that compiles data o the earths biodiversity of plant, animal and fungi
the red list is a method used to communicate the abundance, range, and threats (including trade) about species
how to reduce biodiversity loss
forming international agreements such as CITES and IUCN
CAN =SARA and COSEWIC
parks and protected areas
setting goals
what is SARA
the species at rick act inCAN
a federal agreement to reduce the loss of biodiversity with Canada by ensuring the necessary actions are being taken
what is COSEWIC
the committee on the Status of endangered wildlife in Canada
a committee that proposes recommendations to the SARA
incorporates indigenous knowledge
what is CAN oldest nat park
yellow stone
what is a specifc 2020 CAN goal
by 2020 17% of terrestrial w/ inland water and 10% of caostla marines areas are to be conserved
by
what was decided in COP 15
by 2030 30% of the earths land, oceans, coastal areas and inland waters will be protected
reduce 500 bill of annual harmful gov subsides
but food waste in half
this will be achieved by a roadmap for conservation, protection, restoration, and sustainable management for biodiversity and ecosystems for the next decade (until 2025)
what is OECM
a status awarded to separate entities which achieve long term effect conservation of biodiversity even if the land is managed for an alternative purpose. like they are unintentionally protecting biodiversity
what is Y2Y
a yellowstone to yukon biodiveristy conservation effrot. looking to protect the biodiversity hot spot that spans N to S down the rockies
