3.3.6—Effective conservation factors

Reserve design starts with the target’s territory, breeding, movement and connectivity needs, then adds shape, corridors and buffer zones.

Compact cores reduce edge effects; corridors restore gene flow; buffer zones reduce conflict and compatible-use pressure; transition zones can support sustainable livelihoods. Roads and farms still require management.

Glacier Bay and Admiralty Island Biosphere Reserve in Alaska protects glacier succession, mature temperate rainforest and diverse wetland and marine habitats. A protected core limits activity; buffer and transition areas support research, tourism, managed hunting or fishing and local participation, so conservation is linked to surrounding human use.

Documented movement or gene-flow need between habitat patches, not a corridor drawn without a target.

A larger reserve is not automatically better if it is disconnected, edge-dominated or socially unenforceable.
