Predators Protocol
Purpose
To record avian and mammal predators in the vicinity of fish surveys or other protocols, a boat or shore-based observer conducts surveys of animals that may feed on juvenile salmon and forage fish, also on non-predators that may interact with other protocol or habitat data. These time-based observations identify species, number, and behavior (e.g., foraging, moving, resting) focused on predators. Observations are typically for 10 minutes, and include birds (e.g., osprey, great blue heron) as well as mammals (e.g., harbor seal, river otter). Observations should be conducted before other protocols, in order to minimize disturbance. Binoculars can be used as needed for individual species identifications and behavior patterns, especially when foraging is observed.
Data collection and entry for this protocol can be done in either two ways:
- Standard field datasheet printed out and brought in the field for csv upload later, or
- Data collection and upload via a form that can be done on a phone or other device.
