  1. Legal protection of forests

    A replicated, paired sites study in 1993-2005 in tropical dry forest in Mexico (Ceccon & Hernández 2009) found no effect of forest protection on seed density or diversity of trees and shrubs. The total number of tree and shrub seeds was similar in protected (422/m2) and in disturbed sites (377/m2), as was the number of species/plot (18 in both) and species diversity (Shannon index disturbed: 1.51; protected: 1.66).  Two 10 x 20 m treatment plots were replicated at eight sites: disturbed (intensive cattle grazing, fire wood extraction of >160 ton/year; 0.8 ha) and protected (exclusion of human disturbances since 1993). Viable seeds of trees and shrubs were identified using five seed traps in each treatment plot, which were emptied at monthly intervals in 2004-2005.
