Beaver Census Protocol

The Beaver Census Protocol tracks beaver activity by logging the locations of dams and other signs of their presence, which is used in LTPBR planning to pinpoint sites where beaver populations currently exist or have historically colonized. This helps identify potential locations for translocation or suitable sites for LTPBR implementation.

Layers

The protocol consists of two point layers to assess beaver activity: Beaver Dams and Beaver Signs.

Beaver DamPointobservations of beaver dams
Beaver SignPointobservations of beaver activity besides dam locations, such as lodges, chewed trees, and food caches

Layer Attributes

Beaver Dam

FieldDescriptionValues
Typetype of beaver dam
  • Active Dam: actively maintained by beaver
  • Inactive Dam: no longer maintained by beaver but exists near active colonies
  • Relic Dam: historically maintained by beaver colonies that have been extirpated from system
  • Uncertain: unsure if dam is present or can't classify dam as active, inactive, or relic
  • Confidencelevel of confidence for identifying dam location
  • High: confident that identified location is a dam
  • Medium: reasonably confident that identified location is a dam
  • Low: low confidence that identified location is a dam
  • Beaver Sign
