3. TPO: 2013 Accomplishments National mill canvas form approved by OMB National database now operational Data starting to be uploaded for Missouri National utilization program initiated TPO reports In Press or Published: – Kansas timber industry: an assessment of timber product output and use, 2009 – North Dakota timber industry: an assessment of timber product output and use, 2009 – South Dakota timber industry: an assessment of timber product output and use, 2009 – Wisconsin timber industry: an assessment of timber product output and use, 2008

4. National TPO Database Southern States uploaded most historical data and entering 2012 data into the National Dbase … processing with the National procedures Northern States moving historical data (Missouri first) into the National Dbase with processing system verification ongoing Northern 2012 data will be entered into both the National Dbase and Northern TPO Dbase to verify processing procedures

6. Harvest Utilization Studies

7. Harvest Utilization Regional History Last northern utilization study conducted in 1996 (Wisconsin) Utilization studies have historically been done state by state using regional methods Disparity in methods over time and by state Often conducted by non-FIA crews

8. New National Utilization Effort National Methods Build Upon Existing Southern PDR Program Conducted by P2 crews in concert with forest inventory Sample additional national/volume biomass variables Start in 2014

9. Northern Utilization Specifics Northern study based on utilization regions that have similar species and product mixes About 1,000 harvest utilizations sites will be sampled across the North over the next 5 years Training will be held in early December 2013, and measurement will begin this winter

10. Draft Site Sample Allocation

11. 2014 Goals Begin utilization study MN Annual TPO Full adoption of national dbase for all TPO work SRS conducts annual national pulpwood survey Explore improved data distribution/analysis efforts
