Abstract
Botanical studies conducted in a hilly gypsum area near Zaragoza, NE Spain, have demonstrated that vegetation and geomorphological characteristics were different between hill positions. Both plant distribution and growth were correlated with soil depth and erosion. Heights and number of species of perennial grasses decreased progressively towards the upper part of the hill. Woody species showed similar trends on the top and slopes of the hills. Bryophyta appeared only on the northern slopes. The segregation of various types of plants is attributed to water availability, soil depth and particle movement down the slope.
