Forest Management • What are the critical knowledge gaps? • What synthesis and integration activities can help address knowledge gaps? • What are the next steps to move forward?
Some background #1 of 2 • Forest management can impact C pool sizes by: • Changing production rates (since NEP=NPP-Rh) • Changing decomposition flows (Rh) • Changing amount of material transferred between pools • Changing period between disturbances/mgmt activities. (Source: SOCCR)
Some background #2 of 2 ◘ Little published data has been aimed at quantifying impacts of specific forest mgmt activities on C storage in US--Mexico, Canada? ◘ Definition of forest (agroforestry? Urban forest? afforestation? Reforestation?) ◘ Definition of forest management?: the manipulation of trees and forest stands to meet landowner objectives
SOME TOPICS: #1 of 2 • What are practices with greatest potential? ---(This includes higher C densities, but must know size of area available for practice) Some practices: stocking control, fertilization, fire management, genetically improved trees, partial harvest, Short Rotation Woody Crops, utilization of logging residues, herbivore control, preservation. Tends to be subregional differences
SOME TOPICS: #2 of 2 ◘ Limited data on area of practice ◘ Higher carbon densities may be unhealthy for forest ◘ Uncertainties
Data Based Case StudiesKane EF Hoover et al, RWU NE4152
“Science”…………Operations • National level………stand level • How passively managed stands accumulate C • Which practices sequester more carbon—regeneration. Questions about afforestation effects • National database of practices/areas unknown, maybe • Harvested wood carbon • System boundaries (more of issue for operations • Plantations for energy • Uncertainties in various pools • Fire management, health, and emissions • Maximum carbon accumulation in forests • Landowner choices for management • Ecosystem services
