The surveys are...

Monitoring neotropical migrants on managed land: When, where, why Monitoring neotropical migrants on managed land: When, where, why
Relevant wildlife monitoring on managed lands lies somewhere between monitoring everything and monitoring nothing. Knowing the population status of all birds on a managed area would be potentially useful information but would be costly to collect, but without monitoring no link between management and wildlife populations can be made. A decision making process for developing appropriate...
