The value of integrated land (landscape) classification for the management of wildlife communities was tested by measurement of distribution patterns of 8 vertebrate species [Cervus elaphus, Dama dama, Sus scrofa, Oryctolagus cuniculus, Pica pica, Alectoris rufa, Bos taurus, Equus caballus], using indices derived from transect counts of animals and their signs. Highly significant relationships between animal distribution patterns and objective classification of landscape and seasons were demonstrated. Highest densities of animals occurred near borders of land systems. Methods used highlighted critical areas and yielded, rapidly and economically, information vital for sound management and establishment of national parks. Dangers to the ecological viability of the Parque Nacional de Donana include overgrazing by non-indigenous species within the park and development outside the park of properties formerly acting as buffer zones.
