Chugachmiut Forestry and Fire is currently preparing the Chugach Region Native Allotment
Forestry Management Plan; at this time the plan has not been approved. As part of the
planning process Chugachmiut has been conducting FIA 1 for all Native Allotments in the
region. FIA1 data has been collected for Native Allotment in the region since the 1980’s.
The most recent FIA1 data was collected during October 2010 on 4 Native Allotments west
of Port Graham. The timber inventoried is representative of all timber shown in the
“Native Allotment Woody Biomass” map. There are 4025 acres of accessible mature timber
in the Port Gram vicinity with an average 98 ± 6 2 BDT 3 /acre. Using a very conservative
forest re-growth rate of 100 years the annual allowable cut for Port Graham area Native
Allotments is 3944.5 ± 241.52 BDT3/year. The estimated fuel consumption for this project
is 101 BDT3/year. Based on the FIA1 data and fuel requirements for the project the Port
Graham area Native Allotments can sustainably supply 39 times the estimated annual fuel
required for the project.
Sincerely,
Nathan Lojewski
