Assessing Silviculture Research Priorities For Maine Using Wood Supply Analysis

Problem Addressed: Determining silviculture research priorities using wood supply analysis
Goal(s)/Objective(s): Identify the highest priorities for silviculture research in Maine
Key Findings: Suggested ranking of research priorities among the three silvicultural treatments examined was precommercial thinning > vegetation management > tree planting
Recommendation: Based on long-term wood supply impact, the highest silviculture research priorities should be on pre commercial thinning, vegetation management, and tree planting

The role of vegetation management for enhancing productivity of the world’s forests

Problem Addressed: Influence of competing vegetation on regenerating forests
Goal(s)/Objective(s): Review results from longest-term studies in North America, South Africa, South America, and New Zealand/Australia.
Key Findings: About 25% of studies had volume gains from 100 - 200 per cent. Over half had 50 – 300% yield increases. Three-quarters showed yield gains from 30 - 500%
Recommendation: Managing competing vegetation in young forest stands produces large, early yield gains in forests around the world

The use of composite estimators for estimating forest biomass and growth from permanent sample plots established by the angle count method

Problem Addressed: Using angle count sampling for permanent plots can create issues when computing growth
Goal(s)/Objective(s): Provide a new estimator for determining growth on remeasured plots using an angle gauge
Key Findings: The Bitterlich estimator is a special case of a composite estimate between the new variable basal area factor and its antithetic counterpart
Recommendation: Additivity and efficiency are possible when permanent sample plots are established with a point sampling design

Maximum and Largest Crown Width Equations for 15 Tree Species in Maine

Problem Addressed: Crown width is an important tree attribute, but challenging and expensive to measure.
Goal(s)/Objective(s): Develop equations to predict maximum and largest crown width as a function of DBH
Key Findings: Large differences between species crown widths and a strong relationship with DBH
Recommendation: Crown width equations are useful tool and can be used to derive a variety of forest attributes like crown closure.

Doc for Testing (DO NOT Delete)

Problem Addressed: Describes active research projects in the CRSF Family Forest Program
Goal(s)/Objective(s): Provide relevant research for current issues facing family forests: forest pests, timber harvesting, recreation access, intergenerational transfer, etc.
Key Findings: CRSF is actively engaged in research and outreach that benefits Maine's non-industrial private landowners (also called family forest or small woodland owners). Mainers owning small parcels of land (10-1,000 acres) comprise 34% of the forests in Maine.
