Rewilding/paleoecology Flashcards
rewilding
restoration of ecosystems (releasing from human control/restoring species interactions etc), long term management, need to think of core areas/corridors/carnivores
aims of rewilding
optimism, involve communities
example
knepp wildland, pigs/deer graze and maintain grassland, no predators so controlled by selling meat (some people may not like it)
passive rewilding
happens by accident
rewilding UK
local recovery scheme which rewards landowners for restoring nature, aims to restore 10,000 nature but land owners may take money and not fully restore
paleoecology
study of past ecology/ecosystems to see how climate changed/if species are invasive/how species have moved
ways to study past
anoxic environments which have plants/pollen, sediment cores
pollen, proxy
shows past vegetation
proxy
indirect measure of past climate, found in sediment cores
fungi spores, proxy
some live on animal dung so tells about abundance (coprophilous)
charcoal, proxy
tells about fires
diatoms, proxy
tells about salinity/acidity
what do all proxies follow
principle of uniformitarism, things today are same as before
biases
wind blown pollen dominates insect pollinated pollen in fossil record, pollen may travel far
