Landscape ecology - description of species fragmentation table

This figure graphically depicts the fragmentation sensitivity of a species as a table.

The columns show the dispersal ability (left ot right low, medium, high) and the rows the habitat area requirements (top to bottom high, medium, low) with the fragmentation sensitivity colour coded at the intersection of the columns and rows to represent high, medium and low sensitivities.

The fragmentation sensitivity of a species is a function of the dispersal ability and habitat area requirements.

  • As minimum habitat area increases, and as dispersal distance decreases, species become more vulnerable.
  • Species with excessively high area requirements and low dispersal distances are prone to extinction.
  • Species with high area requirements and low dispersal distances that are not so extreme extinction is inevitable and those species which may respond well to conservation action at the landscape scale.
  • Species which have low area requirements and high dispersal distances are likely to become invasive species.
