Timber plantations near urbanized areas support the movement of small and medium-sized terrestrial mammals between patches of natural forest

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

Researchers studied commercial timber plantations dominated by non-native trees like teak and acacia in Central Panama to assess their role as habitats and corridors for native wildlife. Using camera traps, they found 16 terrestrial mammal species, mostly small or medium-sized and nocturnal, using these plantations, but large mammals of conservation concern were not detected. The study highlights the potential of timber plantations to support biodiversity and connectivity in human-impacted landscapes but emphasizes the limitations of non-native monoculture plantations, advocating for plantations of diverse species to enhance wildlife conservation efforts.
