WESTAR Critical Loads Workshop: Summing Up
Ira Domsky, Deputy DirectorArizona Depart of Environmental QualityNovember 16, 2005
Building the Scientific Base Science is rigorous and well founded
In some ways better than bases for NAAQS
Keying on the indicators Ambient monitoring network – good, but needs
protection Deposition monitoring network – marginal in scope
and potential utility Physical and chemical measurements of soil and
water Species diversity and populations Ecosystems
Diversity of Biotic Communities Alpine tundra Subalpine conifer
forest and lakes Hudsonian/mixed
conifer forest Arid conifer
woodland “Islands in the sky”
High desert Grasslands Evergreen woodlands Chaparral Low desert Riparian areas and
wetlands Ecotones
Building the Scientific Base Funding the research to solidify causal
links FLM budgets Clean Air Act grants to states and locals Universities Foundations Public/private partnerships
Other considerations Climate change impacts
Temperature Precipitation types, quantities and distribution
Existing programs – ozone, PM and Regional Haze
Population growth – traffic, energy and water
Oil and Gas development
Communicating value and values What resources are at risk that are of
concern to people Popular species
Ecosystem Services Watersheds and water resources Sustainability of timber and grazing Recreation – tourism, hunting and fishing
Next Steps – for discussion Develop an action plan Establish an ad hoc WESTAR work group Identify priority areas Move forward with test cases Seeking funding
