• Identify ecologically meaningful scales• Broad-scale (ecoregion), Mid-scale (priority
landscape/watershed or restoration area), fine scale (project site)

Landscape Approach and REAs

You sank my Sage Grouse!!
Looks like a good place for my project…
“A guessing game for two players…” (or more)
Rapid Ecoregional Assessment
What is an REA?
R = Rapid Use existing data and understanding
(18-24 months to complete)
E = Ecoregional Analyze large areas of ecological similarity
(one or more Level III ecoregions)
A = Assessment Summarize current conditions Assess potential change, likelihood/risks
Rapid Ecoregional Assessment
REA Fundamental questions
REAs pose three basic interrelated questions What do we want to develop, restore and conserve?
where; at what scale; and with what trade-offs? How should we organize ourselves?
(at every level of the organization) How should we engage our partners?
state, federal and NGO (at every level)

Ongoing and Completed REAs
Rapid Ecoregional Assessment
Scale and Scope
Study areas Ecoregions based on the Commission for Environmental
Cooperation Level III Ecoregion boundaries (or Omernick) Ecoregions buffered by 5th level hydrologic units boundaries
Analysis and reporting units Spatial scale for resource status evaluation or summary
display, tabulation Varies by issue: 30m pixel, 5th or 6th level HUC (HUC10 or
HUC12), 4 km2
Rapid Ecoregional Assessment
Data Synthesis and Modeling
Driven by management questions Frame priorities: management, conservation, planning
Synthesis of resource data Mostly natural resources; some cultural Understanding socio-ecosystems: conceptual models Geographic distributions of conservation elements
Modeling potential resource change Climate change, development, invasive species, fire Interaction of change agents with conservation elements

REA Applications
Broad-scale context for management decisions, prioritization Allocation; prioritization of conservation, restoration, mitigation Across boundaries (inter-, intra-agency, political) Understand future potential Improve management for sustainability, resistance, resilience
Planning at multiple scales Management unit, watershed, project
Context for smaller scale assessments AIM, land health assessments
