March 29, 2010 Planning for Priority Species and Vegetation: Effects Analysis A Systematic Framework to Plan for Biological Resources In the BLM’s Land Use Planning Process
2
On – Site Training CORE CONCEPTS Develop monitoring framework Identify priority species and vegetation Assess health Identify management strategies Assess effects LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
3
Assess Effects LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
4
Effects Analysis under No Action Alternative IDENTIFY ALTERED KEY ECOLOGICAL ATTRIBUTES: IDENTIFY SOURCES OF ALTERED ATTRIBUTES: Assess Effects to Priority Species and Vegetation LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Altered key ecological attributes describe the ways that priority species or vegetation may be destroyed, degraded or impaired Sources are the proximate cause of the altered key ecological attributes
5
- allowable uses and potential restrictions - management actions needed for protection/restoration IDENTIFY ALTERED ATTRIBUTES: - need for change; management opportunities - restoration needs to meet land health standards IDENTIFY SOURCES OF ALTERED ATTRIBUTES: Effects Analysis LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Assess Effects to Priority Species and Vegetation
6
Key Ecological Attributes Habitat Quality Population Size Connectivity of populations LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION
7
Altered Key Ecological Attributes Reduced Habitat Quality Reduced Population Size Altered Connectivity of populations LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

Ranking of Alterations to Key Ecological Attributes LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Greater Sage-Grouse

Ranking Sources of Alteration of Key Ecological Attributes Contribution -- reasonably expected within life of the plan under no action alternative Very large contributor Large Moderate Small Contribution -- reasonably expected within life of the plan under no action alternative Very large contributor Large Moderate Small Irreversibility -- reversibility of the stress caused by the source Not reversible, for all intents and purposes Reversible, but not practically affordable Reversible with reasonable commitment of resources Easily reversible at relatively low cost Irreversibility -- reversibility of the stress caused by the source Not reversible, for all intents and purposes Reversible, but not practically affordable Reversible with reasonable commitment of resources Easily reversible at relatively low cost LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

Altered Key Ecological Attributes Reduced Habitat Quality Source = Oil and Gas Drilling Reduced Population Size Source = West Nile Virus Altered Connectivity of populations Source = Home Development LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION

LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION Continue this process for all Priority Species and Vegetation This information is then rolled up to provide information across the landscape Assess Effects

‘NO ACTION’ ALTERNATIVE EFFECTS ASSESSMENT -Evaluate predicted effects for the life of the plan under the No Action alternative Use this information to help formulate alternatives LAND USE PLANNING FOR PRIORITY SPECIES AND VEGETATION This analysis will also be done for each alternative to compare the effects under different alternatives
