Implications in genetic reserve
conservation

Narrow distribution with few small populations


Most endangered
Being studied and actively conserved by
environmental protection agencies:




included in Red Lists and legislation of protected species
development of species recovery plans
designation of “genetic reserves”
They are prioritary but attention and care is already
being paid to them.

Action: Better to get in contact with environmental protection
agencies
Implications in genetic reserve
conservation

Continental distribution few scattered small
populations



Various degrees of threat under IUCN criteria at
national level
Various degrees of interest from environmental
protection agencies
The establishment of a network of genetic reserves
requires international coordination that trascends
single or neighbouring countries (greater difficulties)
Implications in genetic reserve
conservation

Regional distribution many populations





Non-threatened under IUCN criteria
Forgotten or neglected by environmental protection
agencies
Nevertheless subject to important decline and genetic
erosion
Most amenable to be integrated in a network of
genetic reserves in protected areas.
Prioritary action is needed.
