Predicted climate change is expected to impact many biological populat
ions independently of their current equilibrium-level community affili
ations. A model is presented that uses environmental response surface,
dispersal potential, plant longevity, and climate change vectors to p
redict the survival of various plant species populations with differin
g terrain types. These types include actual Geographical Information S
ystem (GIS) cases from southern Africa with multiple levels of landsca
pe permeability and discontinuity. Examples include terrain slope conf
igurations that satisfy survival requirements of different plant popul
ations with expected climate change. Copyright (C) 1996 Elsevier Scien
