3.3.5—Habitat conservation strategies

Use protection when preventing disturbance is enough; use active management when a diagnosed pressure blocks recovery.

Name the limiting threat before choosing the action. Active management may remove invasive plants or restore water levels. In a fenced New Zealand ecosanctuary, introduced mammalian predators are removed and pest-exclusion fencing reduces reinvasion, allowing native populations and ecosystem processes to recover.

A reserve protects a wetland from new clearing; if invasive plants already suppress natives, removal and water restoration are also needed.

For a fenced ecosanctuary, verify predator removal, fence integrity, reinvasion risk and native-species response; surrounding land use and distance from urban pressure also affect success.

More intervention is not better; target the diagnosed bottleneck and verify the outcome.
