Non Technical Summary
In concert with characterizing the effects of disturbance, research-based restoration initiatives are needed to address forestlands that are already degraded or vulnerable; in the latter case this refers to overstocked forestlands prone to wildfires, disease, and insect outbreaks. Removal of small diameter timber from overstocked forests will improve forest resiliency; phenotypic characterization of wood resources contributes critical information to permit informed use of such materials as biofuel feedstock, raw materials for advanced wood products, green building materials, and in other innovative applications. Expertise in the identification and classification of fungal systems in forest ecosystems is essential for restoring biodiversity. Saprotrophic fungi, the main decomposers of wood and leaf litter, contribute to soil organic matter, and hence, directly to soil carbon sequestration. Carbon sequestration is also augmented by the higher forest productivity afforded by improved soil fertility. In addition, nearly all terrestrial plants are dependent on mutually beneficial root symbioses with mycorrhizal fungi that increase nutrient uptake and drought resistance, reduce heavy metal toxicity, and provide protection against pathogens. The impact of forest management on the populations and functions of saprotrophic, mycorrhizal, and pathogenic fungi is largely unknown. Accurate identification of the fungal species involved, their relationships, and their ecological roles are therefore needed. The ability to restore forest ecosystems is limited by gaps in our understanding of the distribution and roles of saprotrophic and mycorrhizal fungi in carbon sequestration, nutrient cycling and forest health along with the need to develop technologies (biofuels, green building materials) that will facilitate consumption of underutilized biomass.


Objectives Summary
The objective of this problem area is to restore forest ecosystems by improving our understanding of the distribution and roles of saprotrophic and mycorrhizal fungi in carbon sequestration, nutrient cycling and forest health, in concert with the development of technologies to wisely consume underutilized biomass resources.


Approach Summary
• Assessments will be conducted to determine the effects of woody debris addition and extraction on wood-inhabiting fungal communities.• Applications of soil amendments such as bark mulch will be evaluated for facilitating reforestation by establishing fungus-dominated forest floor microbial communities.• The thermal processing of wood will be assessed for imparting fungal decay resistance to both woody biomass feed stocks (biofuels) and solid wood products (green building).
