36.11.440 SENSITIVE SPECIES - FISHER
(1) The department shall assess fisher habitat
on projects that contain preferred fisher cover types for lands administered by
the department's northwest land office and southwest land office. When
conducting forest management activities, the department shall consider the
following as consistent with 77-5-301 and 77-5-302, MCA:
(a) In blocked areas within the Stillwater , Swan River , and Coal Creek state forests, the department
shall use the grizzly bear BMU sub-unit as the unit of analysis. In all other
areas, the department shall determine the unit of analysis at the project
(b) When managing within preferred fisher cover types that are within 100 feet of class
1 streams or within 50 feet of class 2 streams:
(i) The department shall manage 75% of the acreage (trust lands only) to be in the sawtimber
size class in moderate to well-stocked density. The department shall postpone
treatments where this cannot be accomplished.
treatments reduce stand density below moderately stocked levels, the department
shall make efforts to provide forest connectivity along the opposite stream
(ii) The department shall define a minimum of one buffered management
zone connecting to other fisher habitat through sites where individual
perennial and intermittent stream courses are difficult to define (e.g.,
braided with many channels) .
(iii) The department shall retain large snags, snag recruits and CWD pursuant to ARM
36.11.409 through 36.11.414. The department shall promote recruitment if
existing abundances are below expected levels. Following large-scale stand
replacement disturbance events in preferred fisher cover types, the department
shall give consideration to maintaining an abundance of large snags and CWD
within 100 feet of class 1 streams and 50 feet of class 2 streams.
(iv) When practicable, the department shall avoid constructing new roads in
preferred fisher cover types within 100 feet of class 1 streams or 50 feet of
class 2 streams. Where feasible, the department shall incorporate use of
temporary roads, and obstruct or obliterate unnecessary existing roads.
department shall manage for at least one forested patch providing connectivity
between adjacent third order drainages, preferably in saddles, where landscape
(d) The department shall
consider importance of late-successional riparian and upland forest in meeting
the life requisites of fishers.
