For 2015, the Institute of Forest Resources (IFR) issued four grants through the McIntire-Stennis Cooperative Forestry Research program, totaling $359,477 in funding. All projects are two years in length, and below are more details about the principal investigators and summaries for each proposal.
(The RFP for McIntire-Stennis funding for projects beginning fall 2016 will be available later this quarter.)
1. Potential Soil Carbon Stocks and Turnover Across Privately Operated Forest Stands in the Pacific Northwest: Understanding the Radiocarbon Age, Quality and Lability of Soil Organic Carbon Within Douglas-Fir Plantations.
PI: Professor David Butman
Co-PI: Professor Rob Harrison
In this study, we will look at how altered landscapes, whether through natural disturbance or human land management, affect the storage and processing of carbon in soils. We will characterize the radiocarbon age and biolability of leachable soil organic carbon obtained across a climate and soil parent material gradient in the Pacific Northwest (PNW) as part of a research collaboration with the UW Stand Management Cooperative (SMC). We hypothesize that soil properties and changes in both annual precipitation and temperature regimes will alter the presence, lability and carbon quality of aged soil organic carbon across depths. We are defining quality by the abundance of aromatic carbon structures inferred from absorbance and fluorescence spectrophotometry in the context of carbon lability. These results will provide new information to better manage forest resources in the PNW for carbon storage over short and long periods and will provide new information on the impacts of stand management on soil organic carbon dynamics currently being researched within the SMC.

2. Metal Deposition Along an Urban-Wildland Gradient in the Puget Sound Region
PI: Director Tom DeLuca
Co-PI: Professor Patrick Tobin
Vehicle emissions associated with exhaust, lubricants, and tire and brake attrition represent a major form of pollution in busy urban centers in the Pacific Northwest; however, few studies have focused on characterizing the extent and impact of metal emissions from vehicle traffic on forest bryophytes and ecosystem health. We will evaluate whether metal deposition associated with the transportation sector in the Puget Sound region is altering ecosystem function by influencing forest bryophytes and their associated food webs.

3. Market and Environmental Assessment of Cross-Laminated Timber Production in the Olympic Peninsula: Mid-Rise Non-Residential Construction Application.
PI: Professor Indroneil Ganguly
Co-PIs: Professors Ivan Eastin and Kate Simonen
Cross-laminated timber (CLT), a new generation of engineered wood product, has been gaining popularity in low to mid-rise residential and non-residential construction in several countries, including Europe and Canada. CLT is a cost-competitive and wood-based solution that is a suitable substitute for construction applications that currently use concrete, masonry and steel. We will develop a comprehensive market feasibility assessment for manufacturing CLT in the Olympic Peninsula with a focus on the mid-rise nonresidential green building industry in the Pacific Northwest. We will explore economic avenues for increasing forest resource utilization while developing a regional forest industry on the Olympic Peninsula.

4. Biomass Equations for Coastal Douglas-Fir by Stand Density, Age, Relative Dominance, and Location
PI: Professor Eric Turnblom
Co-PI: Professor Rob Harrison
We will develop a set of equations that describe biomass accumulation and distribution (in terms of stem wood and bark, branches, and foliage) for coastal Douglas-fir in the Pacific Northwest. We have planned for destructive sampling of replicated trees at each level of all factors—density, age, relative dominance, and location—which will yield an orthogonal experimental design with 24 trees sampled in total. We expect the project to yield a set of equations describing above‐ground biomass (by listed components), while the database produced will subsequently be used to develop equations for stem taper, crown morphology, specific gravity along the stem, and other measures of wood quality. The models produced by this study will assist managers in determining how silviculture/ management alternatives affect biomass distribution and related economic and ecologic objectives. The study complements concurrent research by the principal investigator set to yield an analogous set of equations for western hemlock.
