Reduce adverse habitat alterations by excluding problematic terrestrial species
A replicated, controlled study in northern Virginia, USA (McShea & Rappole 2000) found significantly higher numbers of 16 species of ground and intermediate canopy-dwelling songbirds in four 4 ha plots of deciduous forest with deer excluded between 1990 and 1998, compared to five control plots. However, there was no corresponding increase in bird diversity as species were gained and lost as understory vegetation developed. There was also no significant difference in the number of resident birds (eight songbird species and one woodpecker) caught.
