Invertebrate Conservation

Rarity

A species that is described as rare is not necessarily threatened or endangered.

A species' natural state may be rare e.g.

CITES, (Convention on International Trade in Endangered Species) publishes the Red List, which gives the official status of a species.

Species may be listed as

VULNERABLE -

ENDANGERED -

CRITICALLY ENDANGERED -

EXTINCT IN THE WILD -

EXTINCT -

Vulnerable, endangered and critically endangered are all described as THREATENED.

Threats

Conservation action

Complete habitat destruction or change in the physical environment may require relocation or captive breeding.

When planning relocation, we must ask

Captive breeding requires information on the species requirements e.g.

If successful, what then?

Counteracting a reduction in resources may be achieved by reversing the cause. Otherwise, other action may be needed e.g. protection of food source, introduction of an alternative food supply or refuges.

Introduction of competition, disease or predators/parasites may need eradication or biocontrol.
