Final answer:
Large preserves with buffer zones and wildlife corridors are better for fostering biodiversity in local ecosystems.
Step-by-step explanation:
In general, large preserves with buffer zones and wildlife corridors are better at fostering biodiversity compared to smaller, fragmented preserves. Large preserves can support more species, provide more optimal habitats, and attract more species. Preserves in the shape of a square or circle are also preferable to those with many thin arms. These principles are taken into consideration when planning the design of a preserve to ensure the conservation of local ecosystems.
