WESTERN PILOT
Purpose of the Western Pilot• Advance the science of ecosystem monitoring
for western ecological systemsfor western ecological systems– indicators
reference conditions– reference conditions– designs
assessment methods– assessment methods• Build State capacity for long-term monitoring
– monitoring tools– analytical capability– partnerships
Objectives of the Western Pilot• Demonstrate indicators and designs for
measuring environmental progressg p g– unbiased estimates of condition of ecological
resources – comparative ranking of stressors– tools for biocriteria
• Demonstrate the value of survey based monitoring developed by EMAPmonitoring developed by EMAP– apply to real problems of Regional/State
interestinterest
Geographic Scope of the Western PilPilot
• EPA Regions 8– States of North Dakota, South Dakota,
Montana, Wyoming, Colorado, Utah• EPA Region 9g
– States of Arizona, Nevada, California• EPA Region 10EPA Region 10
– States of Oregon, Idaho and Washington
Ecological Resources of the WesternEcological Resources of the Western Pilot
• Coastal systems (estuaries and coastal )waters)
• Surface water systems (rivers and streams)• Landscapes
Components of the Western Pilot• Coastal
– conditions of estuaries by state– focus areas chosen by EPA regional offices
• Surface waters– conditions of rivers and streams by State– focus areas chosen by EPA regional officesfocus areas chosen by EPA regional offices
• Landscapesland cover atlas for the West– land cover atlas for the West
– quantification of relationship between landscape indicators and aquatic conditionlandscape indicators and aquatic condition
– focus areas chosen by EPA regional offices

Region 10 Focus AreasRegion 10 Focus Areas
• Coastal– Tillamook Bay and north coast of Oregon
• Surface WatersSurface Waters– Deschutes and John Day basins
Tillamook Bay watersheds (STAR grant)– Tillamook Bay watersheds (STAR grant)• Landscapes
D h b i– upper Deschutes basin – north coast of Oregon (Newport to Seaside)
Example Coastal Indicatorsp
• Fish communityFish community• Fish pathology
i h i i i• Fish tissue contamination• Benthic community• Sediment contamination (e.g. metals, organics)
• Water physio-chemical (nutrients temperatureWater physio chemical (nutrients, temperature, alkalinity dissolved oxygen, heavy metals, depth)
Example Surface Water IndicatorsExample Surface Water Indicators
• Fish assemblageg• Fish tissue contamination• Macroinvertebrate assemblage• Macroinvertebrate assemblage• Periphyton• Physical habitat (e.g. riparian characteristics, woody
debris, canopy cover, gradient)• Water physio-chemical (e.g. nutrients, temperature,
alkalinity dissolved oxygen, heavy metals)
Example Landscape Indicators
• Riparian indicators– land cover along streams– disturbance (e.g. grazing)
• Watershed indicators– land use and cover – upland erosion– natural cover diversityu cove d ve s y– impervious surfaces– population densitypopulation density
Value of Improved Approaches to i iMonitoring
• Monitoring for resultsMonitoring for results– GPRA objectives
T ti• Targeting– most important areas– most important stressors
• Support development of biocriteria• Support for specific assessments

Key Elements of the EMAP ApproachKey Elements of the EMAP Approach
• Ecological (i e biological) resources• Ecological (i.e., biological) resources• Direct measures of condition• “Integrated” condition• Reference conditions• Surveys for unbiased results• Ranking of stressors• Ranking of stressors• Spatial comparisons
Survey Design AdvantagesSurvey Design Advantages• Guarantees representation and inference toGuarantees representation and inference to
systems of interest• Adapted to resource characteristics• Adapted to resource characteristics• Adjusts sample sizes to meet precision
i trequirements • Adaptable to temporal and spatial scales of
resolution
Lessons from Mid Atlantic Pilot
• True ORD/Regional partnerships necessary– Internal Regional and ORD commitment top to
bottom (long-term)• Biological and habitat indicators compliment
current chemical monitoring, can be used now and are economical
• Sound environmental characterization can drive management decisions and influence public perceptionsp p p
Lessons from Mid Atlantic Pilot (cont.)( )• Statistical surveys are very important to
setting goals and meas ring progresssetting goals and measuring progress
• Expanding use of environmental indicatorsExpanding use of environmental indicators and statistical surveys changed the view of relative riskrelative risk
• Long-term outlook essential
• Partnership/stakeholders involvement is iti lcritical
