Restoration Strategies to Improve Connectivity for Golden-Headed Lion Tamarins (<Emphasis Type="Italic">Leontopithecus chrysomelas</Emphasis>) in the Bahian Atlantic Forest,Brazil

Habitat loss and fragmentation are the leading causes of biodiversity decline world-wide. Animals sensitive to fragmentation experience reduced dispersal, breeding opportunities, and genetic diversity, making them vulnerable to local extinction. Over the last few decades the Atlantic Forest of Brazil has been extremely fragmented, with only 11–16% of forest remaining. The Brazilian government and nongovernmental organizations have taken actions through legislation and conservation initiatives to restore forest. Using computer modeling, we compared how alternative forest restoration strategies could improve functional connectivity for golden-headed lion tamarins (Leontopithecus chrysomelas) in Southern Bahia, Brazil. Strategies differed by restoration configuration, including Within- and Across-Property approaches, and restoration amount (0–20% restoration). Increasing restoration amounts resulted in greater species functional connectivity, and Within-Property and Across-Property strategies both had significantly more connectivity than the Random strategy. We suggest restoration management consider the size and placement of restored forest, and that riparian forest be restored first to create dispersal corridors and reestablish essential ecosystem services. We further suggest the importance of forming canopy bridges across narrow sections of rivers during the early stages of the restoration process to promote increased connectivity of these newly restored areas. Our findings can aid managers and landowners in understanding the implications of different restoration strategies for highly arboreal, matrix-sensitive species.
