The role of Sansevieria intermedia in degradation and recovery in Kenyan drylands

摘要：

Introduction In some heavily grazed rangelands of north-central Kenya,many local pastoralists are concerned over the proliferation of Sansev ieria intermedia,a leaf succulent that forms dense patches and prevents livestock foraging and passage.As a first step toward understanding the dynamics of the increase of S.intermedia,this paper presents findings of both traditional and scientific ecological knowledge of the system,which suggest two key hypotheses regarding degradation and recovery dynamics.
