Modeling Seral Stage Requirements. During the previous IFPA analyses, use of the Aspatial Old Growth Assessment Units with the draw- down for the first period (years 2002-2006 in the analysis) was investigated, however since the Xxxxxx LRMP targets were more restrictive in terms of the targets it was decided to solely use the Xxxxxx LRMP seral targets. The area of assessment for this constraint was the crown forested area. In contrast the TSR3 analysis used the Aspatial Old Growth Assessment Units to model old seral and the LRMP seral targets to model early seral within the General Forested Area (GFA). The LRMP seral targets were used for the High Biodiversity Emphasis Area (HBEA). The GFA seral stage targets are shown in Table 37, and the HBEA seral stage targets are shown in Table 38. Table 37.
