What information do you need to know before targeting conservation activities?
variety of plant and animal species population size of species weather/climate the importance of each species what is causing the population decrease
What does IUCN stand for?
International Union for Conservation of Nature
What is the IUCN?
a membership union composed of both government and civil society organisations
What does is the aim of the IUCN?
preserve species promotes national legislation monitors climate change improves the lives of people through the economic conjunctions of nature
What are the roles of the IUCN?
compile red list reduce poverty boost food security restore natural resources reduce company’s environmental impact
What is the IUCN Red List?
gives species a status of vulnerability contains both threatened and non threatened species
How is the Red List compiled?
measures pressure on species local surveys, consultations, national red lists 70000 species are currently listed - target 160000
The seven categories of the red list and what they mean: EX
extinct
The seven categories of the red list and what they mean: EW
extinct in the wild can only be found in captivity
The seven categories of the red list and what they mean: CR
critically endangered extremely high risk of extinction
The seven categories of the red list and what they mean: EN
endangered very high risk of extinction
The seven categories of the red list and what they mean: VU
vulnerable high risk of extinction in the wild
The seven categories of the red list and what they mean: NT
near threatened close to qualifying for a threatened category
The seven categories of the red list and what they mean: LC
least concern
How are the different categories assessed?
population size (change over past 10 years) area of habitat number of areas found in number of mature adults probability of extinction
Definition of EDGE species
Evolutionarily Distinct and Globally Endangered species
Examples of EDGE species
elephants pangolins purple frog pandas
EDGE Species conservation study: pygmy sloth
educational programs monitor populations - GPS collars/backpacks only found on an island near Panama
Definition of Endemic Species
species that are only found in a limited/defined area or habitat
Examples of endemic species
giant panda pygmy sloth glacier bear
Endemic Species conservation case study: Giant Panda
increase area of habitat protected by law patrol against poaching, logging and encroachment creating green corridors to connect isolated pandas moved from endangered to vulnerable
Definition of Keystone species
an organism that is a fundamental part of the functioning of an ecosystem
Examples of Keystone species
the american beaver sharks bees starfish
Keystone species conservation case study: starfish
when removed half of other species gradually declined mussels overcrowded other species as were not being kept under control
