S&PF Assessment Tool Overview 3
S&PF Assessment Tool Overview • Web-based GIS decision-support system • Capable of supporting analysis of customized data-sets and scenarios at the National/Regional/State level to guide forestry planning and decision-making. • Highlight conditions and trends, and help identify opportunities and priorities for multistate and multi-agency investment and cooperation 4
S&PF Assessment Tool Process • Standard GIS Weighted Overlay Process – Combination and weighting of multiple factors • Advantages: – Integrative and Collaborative Process – Transparency and Repeatability – Interactivity and Scalability – Comparability Across Geographic Regions (If standard data are used) – Ability to Share and Document 5
S&PF Assessment Tool Process • Utilizes raster-based spatial format compatible with Arc. GIS (Geo. TIFF) • Preloaded National Data Available (1 km) – Used for National Assessments – States can also utilize to augment their data • States should use their own finer resolution data, if available. – 2 -GB file size limit – Upload via FTP 6

S&PF Assessment Tool Prepare Data Processing Steps: • Upload and name your data layers… • Reclassify data layers – allows the user to decide “high priority” values • Masking data – highlights data to area key to the analysis (Forest Mask); 10
Geospatial Assessment Process • Can build on Forest Stewardship Spatial Analysis Project (SAP) • The Data Layers from SAP can be used in the State Assessments • The weighted overlay analysis used in SAP is similar to this process 11
S&PF Assessment Tool Data Disclaimer All data-layers associated with a single analysis must have a common geographic extent, pixel size, pixel alignment, datum, and projection in order for the analysis to produce meaningful results. 12
S&PF Assessment Tool Prepare Themes • Refined Questions for Each S&PF Redesign Theme Conserve Working Forest Lands Protect Forests From Harm Enhance Public Benefit from Trees & Forests Where is productive forest land most threatened by development and fragmentation? Where are forests most threatened by insects, disease, and wildfire? Where can protection of threatened and endangered species (as a proxy for biodiversity) be most beneficial? 13
S&PF Assessment Tool Themes & Objectives • States may add their own objectives • States decide the relative importance of the national objectives • States should define the objectives to address their specific State issues - this is “identifying criteria”… – Requires Collaborative Involvement 14
S&PF Assessment Tool Ranking / Weighting • Determine Goals/Priorities • What is most important in meeting theme goals? Fire, Insect & Disease, Water? • Subject area bias, how do we prevent this? – Those doing the ranking should have influence and oversight over multiple disciplines. – Broader agency goals and existing plans 15
S&PF Assessment Tool Data Aggregation • Chose desired mask and aggregation method (e. g. Forest, Watershed) • Difficult to work with “pixels” on a landscape level – Aggregated map a better communication tool • Not all layers overlap • Preventing unintended uses of the data – “My favorite pixel” • Local decisions still based on local data/information 16
S&PF Assessment Tool View/Edit Scenario • Evaluate Intermediate/Final Results – Easy to see what is driving the maps • Change Weights and Re-Run Outputs – Scenarios (Gaming) • Different Aggregation Units • Swap in Higher Resolution Data 17

S&PF Assessment Tool National Themes & Objectives Theme Objective Conserving Identify and conserve high priority forest ecosystems and Working Forest landscapes. Landscapes Actively and sustainably manage forests. Protect Forests Restore fire-adapted lands and reduce risk of wildfire impacts. From Harm Identify, manage and reduce threats to forest and ecosystem health. Enhance Public Benefits Associated with Trees and Forests Protect and enhance water quality and quantity. Improve air quality and conserve energy. Assist communities in planning for and reducing wildfire risks. Maintain and enhance the economic benefits and values of trees and forests. Protect, conserve, and enhance wildlife and fish habitat. Connect people to trees and forests, and engage them in environmental stewardship activities. Manage and restore trees and forests to mitigate and adapt to global climate change. Themes and Objectives are based on Section 8001 of the 2008 Farm Bill – National Priorities for Private Forest Conservation and were approved by the RIC. 19

S&PF Assessment Tool Status/Update 39
S&PF Assessment Tool History • Initial Design and Development – May 07 to Sept 08 – Requirements Analysis – Data (Availability, Consistency) – Prototype Development (Error Detection, Refinement) • Prototype Enhancement – Nov 08 to Aug 09 – – Streamlined user-interface/workflow Output (Reports, Map Viewer) Data (Local Data, Processing) Role-based access (National, Regional, State) 40
S&PF Assessment Tool Current Status • Transition from ESRI development environment to Interim Hosting Environment (Len. Tech) – New Production Configuration – New Test/Development Environments • Available For Use – Jan ‘ 10 – Pre-Production Use – Ongoing Development/Testing 41
S&PF Assessment Tool Next Steps • Mandatory Security Requirements – USDA e. Authentication – Security Certification & Accreditation (C&A) • Migrate to Government Data Center • Data/System Administration (ongoing) • Application Maintenance & Enhancements – Internet Explorer v 7/8 compatibility – Enhanced On-Line Help/Tutorial – Data-Preparation & Output Transformation 42
S&PF Assessment Tool Lessons Learned • Need clearly defined goals and objectives – what questions are being addressed by analysis. – Interdisciplinary Team (GIS & Program Experts) – Decisions made by Leadership • Refined/Streamlined workflow • Data limitations. – Improvement/Development Needs – Scaling issue(s) with Urban & Community Forestry • Risk vs. Opportunity 43
S&PF Assessment Tool Lessons Learned • Need visualization tools to aid in assessment process decisions. • Need for standardized language (semantics). – Consistency – Understanding • Efforts to make tool user-friendly to “lay” people did not extend to Data Preparation – still requires some level of GIS expertise and knowledge of data. 44
