The simple and control fences did not differsignificantly according to this diversity index. This may bebecause both simple and control fences are most frequentlyvisited by generalist species (e.g. granivores and generalistspecies that frequent pasture areas as well as perch infences). Diversity indices are just one description of thecommunity, on par with species lists or other metrics(Barbour et al., 1999). However, both indices suggest thatmultistrata fences may have the higher conservation valuesince we expect richness to be one of the best predictorsof areas or patches with highest conservation potential(Bock et al., 2007).Data from a mist netting study conducted in differentplots at the same study site have shown that individualrecaptures are less common in agroforestry plots and livefences than local forest patches (Martínez-Salinas andDeClerck, 2009). This suggests that agroforestry plots andlive fences may facilitate movement between other elementsof the agricultural matrix, but do not provide high qualitypermanent habitat.
