1922.2 – Forest Plan Content
1922.21 – Standards for Forest Plans
Following are the minimum requirements for all Forest Plan revisions and amendments. They
are adapted from the withdrawn Rocky Mountain Regional Guide, as amended in May 1992 and
corrected in June 1996. The Silvicultural Requirements are adapted from Standards and
Guidelines that were documented in a Record of Decision in May 1992, and direction in R2
supplement to FSM 2470 and R2 supplement to FSH 2409.26.
1. Silviculture Requirements. Update silviculture direction in Forest Plans as follows
during Forest Plan Revisions or Amendments:
a. Identify acceptable silvicultural systems that are best suited to the multiple-use
goals established for the forest. Identify allowable stand improvements and
regeneration methods. Indicate where even-aged timber harvest methods are limited.
In developing this list, choose from the silvicultural systems listed in the R-2 FSH
2409.26 chapter 20.
b. Provide a maximum size limit for openings created by even-age management. If
greater than 40-acres, the requirements of R2 FSM 2471.1 apply. Identify any
dispersal or size variation requirements. Describe conditions where created openings
can be placed next to natural openings.
c. Identify the conditions when a regenerated site has been adequately restocked.
d. Identify when artificially created openings will no longer be considered openings.
Consider when the trees in the openings have reached a height and density that meets
the objectives established for the management area. Include an explanation that the
criteria will be validated or modified based upon local conditions encountered during
implementation. Consider the following criteria in determining when an opening is
no longer an opening:
(1) The desired future conditions planned for the management area.
(2) Visual sensitivity of the area.
(3) The character of the landscape.
(4) Abundance, quality, and need for cover for big game animals.
(5) Other vegetation that may be present (such as tall shrubs).

(6) Forest health.
(7) Need for seed sources.
(8) Need for interior forest area.
(9) Production of wood fiber.
(10) Watershed and riparian area protection.
e. Describe when final harvest of even-aged stands can occur prior to culmination of
mean annual increment (CMAI). Factors to consider include:
(1) Historical range of variability of stand structure and composition.
(2) Habitat for threatened, endangered, or sensitive species.
(3) Stand health. Where disease can spread from an uncut stand to a newly
regenerated stand, provide direction for the uncut stand.
f. Include utilization standards for live and dead trees that lie within the limits shown
in R2 FSH 2409.12 chapter 10 unless a volume recovery study supports different
limits.
2. Transportation and Utility Corridors Requirements.
Update or modify transportation and utility corridor designations as appropriate during Forest
Plan Revisions or Amendments, indicating those uses shown below:
