State Trust Lands Habitat Conservation Plan
What does effectiveness monitoring do?
- Determines whether implementing conservation strategies results in expected habitat conditions
- Considers cause-and-effect relationships
- Is either passive (retrospective studies of existing research; following existing silvicultural prescriptions) or active (designing field experiments; developing prescriptions)
What are the purposes of effectiveness monitoring?
- Documenting short-term (1-3 years after silvicultural treatment) and long-term changes in habitat conditions. A variety of habitat attributes are measured, such as:
- Forest stand structure (tree size, density, canopy closure, etc.)
- Large woody debris
- Marbled murrelet nesting platforms
- Evaluating the effects of different silvicultural treatments designed to enhance and/or maintain habitat
What effectiveness monitoring projects is DNR working on?
Northern Spotted Owl Conservation Strategy
Riparian Conservation Strategy
- Monitoring of Instream Habitat Conditions and Trends
- Studying Riparian Silviculture Treatment Alternatives
- Monitoring Water Quality on Mill and Abernathy Creeks
Where is DNR's effectiveness monitoring done?
- On DNR lands managed under the Habitat Conservation Plan - all planning units
- Map of northern spotted owl habitat effectiveness monitoring sites
