Field techniques refer to the standardized methods employed to select, count, measure, capture, mark, and observe individuals sampled from the target population for the purpose of collecting data required to achieve study objectives. The term also includes methods used to collect voucher specimens, tissue samples, and habitat data. The choice of field techniques to use for a particular species or population is influenced by five major factors:
Data needed to achieve inventory and monitoring objectives
Spatial extent and duration of the project
Life history and population characteristics
Terrain and vegetation in the study area
Budget constraints
