Use wire fences within grazing areas to exclude livestock from specific forest sections
A replicated, controlled study in 2002-2005 in dry tropical forest in Panama (Griscom, Griscom & Ashton 2009) found that cattle exclusion increased basal area, density and species richness of new regenerating trees. Fenced plots had larger basal area (fenced: 0.03; grazed: 0.01 m2/plot), density (fenced: 19; grazed: 10 stems/plot) and species richness (fenced: 6; grazed: 4 species/plot) of tree regenerations >1 m height compared to grazed plots. Data were collected in 2005 in 48 grazed (0.6–0.8 head/ha) and forty eight 100 m2 plots fenced in 2002.
