Ecogeographic Surveys

The current threat to plant genetic resources from global genetic erosion has led to an increased need for their conservation through in situ and ex situ conservation strategies. As discussed in Unit 8.1.1, genetic erosion can be caused by a number of factors including:

Agricultural change
Socio-economic change
Over-exploitation
Habitat loss
Competitors, predators and pests
Natural disasters/pollution

To recognize and react to any threat of genetic erosion of plant species or populations, accurate, timely and relevant information is needed. Ecogeographic studies can provide invaluable information in assessing the threat of genetic erosion. Ecogeographic information can be used for the identification of conservation priorities and the development of conservation strategies. Importantly, it is essential for planning collecting missions.
