Carbon Accounting Timber Products Output Christopher Woodall Group Leader
Staff Timber Products: Ron Piva (analyst), David Haugen (analyst), Brian Walters (analyst/programmer) National Carbon Accounting: James Smith (scientist), Michael Nichols (programmer), Grant Domke (scientist) State Responsibilities: North Dakota, South Dakota, Missouri
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
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

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
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
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
2013 Accomplishments Made it into 2014 NGHGI Review Version (first time in many years) Contributed to: National Climate Assessment, National Forest C Baselines, Federal Land C Budget Published National Analysis of DWM P3 data New research outputs (e.g., maps, dead wood)

Forest Floor Initially proposed by Ohmann & Gregory (2002) Can. J. For. Res. 32:725-741 A nearest neighbor imputation method – Similar to kNN and MSN Accommodates a multivariate response – Nearness metrics are based on Canonical Correspondence Analysis (CCA) outputs

NASA Research Carbon monitoring systems National biomass mapping based on lidar and FIA data Using Landsat to inform C baselines across 1990’s to present
2014 Carbon Efforts Complete the numerous studies currently underway Move forward with biomass change estimation (saw log top paper soon in JOF) Release of P2+ DWM data and estimation procedures P3 soils data as part of NGHGI
