Plan Area Adjustments Over Time. During the term of the Plan and Permits, Green Diamond may elect to add commercial timberlands to the Plan Area within any of the 11 HPAs by submitting to the Services a description of the lands within the Adjustment Area that it intends to add, along with a summary of relevant biological and physical characteristics that they share with existing Plan Area lands in that HPA. As discussed above, Green Diamond estimates that there are approximately 291,377 acres of other commercial timberlands in the 11 HPAs that could be added to the Plan Area if acquired by Green Diamond in the future. However, the IA limits expansions of the Plan Area under this process to 15% of the Initial Plan Area (approximately 62,480 acres). This estimate is based on the acreage of the Adjustment Area within the HPAs as of the effective date of the Permits (see Table 1-1). Further, through a notification to the Services, the Plan Area would contract automatically with sales or disposals of commercial timberlands in the 11 HPAs unless the contraction of the Initial Plan Area exceeds 15%.
