Biomass/Whole Tree Harvest: Soil Effects and Measurement Methods
|
Project Background
Utilization of down woody material is a source of biomass fuels. However, there is concern that the removal of this material may have negative impacts to long term soil productivity, particularly on nutrient poor, sandy, outwash soils.
Specific questions addressed in the project include:
- How to identify how much down material is needed to maintain or enhance soil productivity?
- Development of Risk Rating for Biomass and Whole Tree Harvest (WTH) – Ongoing Study with Michigan Tech.
- Biomass Fuels and whole Tree Harvesting Impacts on Soil Productivity: Review of Literature
- How to describe/designate the amount of material that can be rmoved or must be left in a timber sale or similar contract?
- Links to Sample Contracts Specifications will be included
- How to readily measure surface fuels and biomass?
A compilation of different methods available to measure surface fuels and biomass including the following:
- Line-intersect
- Fixed Plot
- Visual sampling
Full discussion and links to Brown's Planar-intersect method, FIA downed woody material, and FEAT/FIREMON Integrated (FFI), photo series including photo load and fuel models that are used to estimate surface fuels.
