Hi-Grouse Project Fire and Fuels Report Amendment 1

Hi-Grouse Project Fire and Fuels Report Amendment

This amendment to the Hi-Grouse Project Fire and Fuels Report evaluates the effects of modifications to 

the alternatives on the analysis completed in August 2009.

Background

In December 2009, upon review of updated goshawk habitat information and further analysis, it was 

discovered that Forest Plan goshawk Standard and Guideline (S&G) 8-20 would not be met under any 

alternative. To meet goshawk S&G 8-20, alternative 2 would require substantial changes that would 

move it closer to alternatives 3 and 4; alternatives 3 and 4 would require slight modifications. 

On January 4, 2010, District Ranger Laura Allen reviewed the information from the ID team and 

recommended the proposed action (alternative 2) be dropped from further study, because it would not 

comply with NGH S&G 8-20, and modify alternatives 3 and 4 meet Forest Plan S&G 8-20. Forest 

Supervisor Patricia Grantham concurred with the recommendation and decided to drop the proposed 

action (alternative 2) from detailed study. Alternative 4 incorporated similar prescriptions as the original 

proposal and was identified as the modified proposed action.

Modifications to alternatives 3 and 4

The modifications to alternatives 3 and 4 include dropping approximately 86 acres and 108 acres of 

treatment, respectively. In addition under alternative 4 a modification in the treatment prescription for 

one unit was identified to maintain a higher level of basal area to maintain a higher level of canopy 

closure. See tables 1 and 2 for affected units and modifications to alternatives 3 and 4, respectively.

Table 1 Alternative 3 modifications to affected units

Unit # Original prescription and acres Changes/modified prescription and acres

11 192 acres underburn Unit boundary changed to drop 76 acres from treatment. 

Remaining 116 acres with underburn treatment

HTH-LP treatment

13 183 acres of HTH-LP 1 acre will be excluded from unit, or left in untreated clump.

Review of effects analysis

The units where treatments were dropped in alternatives 3 and dropped and modified in alternative 4 

are dispersed in the western half of the Hi-Grouse project area. 

The small reductions in treatment over the 7,450 acre project area is not anticipated to change the 

overall model outputs since the units dropped from treatment are dispersed. The modifications to 

alternatives 3 and 4 would not change the relative effects discussed in the August 2009 Fire and Fuels 

Report.
