  1. Prevent livestock grazing in forests

    A site comparison study in 1996 in tropical dry forests in Costa Rica (Stern, Quesada & Stoner 2002) found that preventing livestock grazing increased plant species richness and diversity. The grazed site had lower numbers of species (grazed: 56; ungrazed: 84) and species diversity (Shannon's index grazed: 2.9; ungrazed: 3.5). Species richness and diversity were calculated using 150 individual plants identified along each of six 2 m wide transects in each ungrazed (since 1990) and grazed sites (grazed in May-January by 1.0-1.4 cattle/ha since 1991).
