Setting Conservation Priorities Flashcards
Questions to be asked when discussing best strategies conserve wildlife
- What is present day situation - species present, populations, current changes abiotic factors
- Which species should b protected - r they harmful or beneficial other species
- what action taken conserve desired species
- can outcomes b accurately predicted
- can impacts be monitored accurately inform further decision making ?
Many habitats/ species endangered - some perceived as more important to protect than others
Setting conservation priorities
International union for conservation of Nature (IUCN)
Role of ICUN
- coordinate global data on biodiversity conservation
- increase understanding importance of biodiversity
- deploy nature based solutions to climate, food and sustainable development challenges
ICUN list categorises species according
ICUN Red list categories
Extinct Extinct in wild Critically endangered Endangered Vulnerable Near threatened Least concern Data-deficient Criteria based on population decline, habitat loss, areas found, no. Mature adults, probability of extinction
Some examples of recatogrised species 2016 2015 2014 2013
2016 - plains zebra - leader concern to near threatened - habitat loss
2015 - white headed culture - vulnerable to critically endangered poisoning and persecution
2014 - 22 lemur species critically endangered and 48 endangered - 100 total no of species
2013 - kori bustard sub-Saharan Africa - hunting for traditional medicine leader concern to near threatened
Only 85,000 species asses and categorised as require lots of research
Criteria to used to select species for categorisation include:
Species in habitat under particular threat
Evolutionary unique specie
‘EDGE’ species
Endemic species
Keystone species
(African forest elephants keep paths open, spread seeds, keep waterholes open)
Flagship species
Degree of population dispersal
