Abstract

The objective of this study is to determine if a main gradient is detectable in the woody plant composition in this hyper- to semi-arid environment; and to which extent climatic and edaphic variables account for it. A cluster analysis detects two plant functional groups: a tropical desert formation and a shrub and dry forest formation. Variation partitioning reveals edaphic variables to be more important in structuring vegetation than mean annual rainfall. Extending irrigation in parts of the study area may possibly be beneficial for local residents. However, it will almost certainly trigger the extinction of the last remnants of the highly endemic tropical dry forest formations
