We measured productivity and diversity of annual plant communities in humanâmade pits and mounds (20 ° 30 ° 100 cm) in the Northern Negev of Israel. We differentiated the species according to propagule size, dispersal mode, and geographical distribution in Israel. Our results in 28 experimental units containing a pit, a mound, and a portion of the undisturbed surrounding "matrix" showed that species richness, total plant density, and biomass yield were higher in the pits and mounds than in the matrix.
