Abstract
McAuliffe studied the factors limiting seedling establishment of a common Sonoran Desert tree, Cercidium microphyllum, at three sites in bajada habitat in Arizona and Mexico. Distribution patterns of Cercidium seedlings in both habitats were random when seedlings emerged, however, seedling distribution in bajadas quickly became non-random and associated with other perennial plants. Seedlings closely associated with (rooted under) shrubby perennial vegetation survived because they had some protective cover and were not grazed by rabbits, however, future survival of these seedlings may be reduced due to competition with the protective plants. The authors concluded that herbivory was the main factor limiting the establishment of Cercidium microphyllum seedlings in the bajada habitats in the Sonoran desert.
