Purpose of Today’s Discussion
Overview of the BLM’s Landscape Approach Rapid Ecoregional Assessments Monitoring and adaptive management

Vision for BLM’s Landscape Approach
3
Vision for BLM’s Landscape ApproachDevelop business practices to manage resources and uses at multiple scales in the face of compounding stressors. These practices will help the BLM and partners identify what to sustain, at what scale, and the associated trade-offs.
Traditional Practice Landscape Approach
Project and Site Focused Landscape Focus
Stove piped Integrated
Tends to authorize uses and mitigate ecological values
Considers ecological values and use authorizations equally
Ecological Component (Individual Species)
Ecological Function and Service
Develop new business practices to support this transition
Frame the issue: Build conceptual models with conservation elements and change agents.

The Landscape Approach is based on management
questions and an understanding of the system

Rapid Ecoregional Assessments
ScienceIntegration(CSCs & LCCs)
Rapid Ecoregional Assessments are the
first step in the Landscape Approach

Rapid Ecoregional Assessments Underway
10 REAs initiated to date
7 REAs covering more than 370 million acres will be completed in 2012
Negotiations in progress for additional REAs this year

Three Components of REAs
Conservation Elements + Change Agents = Management Questions
EX:Species
Habitat Soils
EX: Invasive Species
FireClimate
ChangeHuman
Development
EX: Where is intact sage-grouse habitat threatened by climate change?
“what we want to conserve”
“what is threatening our resources”
“what land managers need to know”

13Sample Design
Low-intensity, “extensive” national sampling effort
Higher-intensity, “intensive” local sampling effort (driven by local management questions)
14
Extensive Sampling*
Intensive Sampling*
•Low density network of sampling locations
•Higher-density sampling for local management needs
Integrated Sampling• Intensive data combined with extensive network
•Increases precision of extensive sampling resource estimates
•Comparability of resource values across scales and jurisdictions
Sample Design
*Hypothetical points for illustration only
