Vestal Final Environmental Impact Statement Chapter 2 actions are expected to be substantially complete and when the MPB epidemic is predicted to have run its course in the project area. Table 3 shows the changes in cover types between the existing condition and the two alternatives. The only differences are in acres of aspen and ponderosa pine, as 126 acres of hardwood conversion are proposed. All other cover types would remain unchanged. Table 3. Comparison of Cover Types 28 Alternative 1 No Action Alternative 2 Proposed Action Year 2018 Cover Type Existing Condition Year 2011 Year 2018 Meadow 1,482 1,482 1,482 Aspen 431 431 557 Spruce 42 42 42 Ponderosa Pine 23,693 23,693 23,567 Water 29 29 29 Rock 146 146 146 Total 25,823 25,823 25,823 Table 4 and Figures 2-4 present estimated acres of pine structural stages for the existing condition and both alternatives, at year 2018. The changes in Alternative 1 are due to expected changes from MPB caused mortality, based on assumptions developed by the project entomologist. The specific sites on where these structural stages would occur are speculative. Therefore, the total acres of projected structural stages are presented for comparison. Refer to Table 12 in Chapter 3 for definitions of each structural stage. Table 4. Comparison of Ponderosa Pine Structural Stages Ponderosa Pine Structural Stages Alternative 1 No Action Alternative 2 Proposed Action Year 2018* (acres) Existing Condition Year 2011 Year 2018* SS1 87 7,082 77 SS2 269 2,530 1,275 SS3A 770 4,890 597 SS3B 1,270 1,168 111 SS3C 1,295 0 114 SS4A 6,924 6,716 18,438 SS4B 10,267 1,297 2,496 SS4C 2,704 0 352 SS5 107 10 107 Total 23,693 23,693 23,567** *Total acreage for Alternative 2 is lower than existing and Alternative 1 due to Hardwood Conversion treatment which increases aspen acres by 126 acres.
