Resumen:
Agriculture and development transform forest ecosystems to
human-modified landscapes. Decades of research in ecology have generated
myriad concepts for the appropriate management of these landscapes. Yet,
these concepts are often contradictory and apply at different spatial
scales, making the design of biodiversity-friendly landscapes
challenging. Here, we combine concepts with empirical support to design
optimal landscape scenarios for forest-dwelling species. The supported
concepts indicate that appropriately sized landscapes should contain >=
40% forest cover, although higher percentages are likely needed in the
tropics. Forest cover should be configured withc. 10% in a very large
forest patch, and the remaining 30% in many evenly dispersed smaller
patches and semi-natural treed elements (e.g. vegetation corridors).
Importantly, the patches should be embedded in a high-quality matrix.
The proposed landscape scenarios represent an optimal compromise between
delivery of goods and services to humans and preserving most forest
wildlife, and can therefore guide forest preservation and restoration
strategies.
