Abstract

In order to analyse the distribution patterns of vegetation types and plant biodiversity in Madagascar, a new vegetation map was produced using Geographical Information System techniques. A vegetation map based on Landsat imagery was superimposed onto a simplified map of geology and a map of "Remaining Primary Vegetation classified by the underlying Geology" was produced. Proportions of each vegetation type within protected areas were calculated by comparing this map to one of the system of National Parks and Reserves. The first analyses showed strongly that the scrublands and dry deciduous forests in the south of the country were insufficiently protected. The map has proved useful in conveying conservation messages, and in the selection a new series of protected areas.
