Your landscape analysis assignment will focus on analysis of landscapes in the
Craig Mountain Wildlife Management Area, south of Lewiston, Idaho.
The analysis area is 65,000 ha (about 250
mi2). Elevations range from 230 to 1500 m (750 to 5000 ft),
from the Snake River to the Craig Mountains. The canyon grassland
ecosystem extends upward from the Snake and Salmon Rivers to ponderosa
pine, Douglas-fir, and grand fir forests at the highest elevations. The
area is heavily used for hunting and other recreation. The highest
elevations are gently rolling, mostly forested, and roaded. Timber harvest
and grazing occurs. The upper breaks are steep, dissected, with
interspersed forest and grassland largely determined by aspect. The lower
slopes are steep and highly dissected. The riparian and flatter areas show
legacy of cattle grazing, pasture, crops and homesteading. Up
to 50 homesteads were present in the 1930’s, and there were 5 schools.
Multiple streams drain Craig Mountain, some support anadromous fish
(steelhead) and red-banded trout. More
than 200 different bird and mammal species potentially live on Craig
Mountain. Weed distribution and spread is a serious threat to the
ecological integrity of the grasslands and open forests, and probably to a
number of invertebrate and vertebrate species dependent on those habitats.
Current invasive species include: yellow starthistle, common crupina,
leafy spurge, Scot’s thistle, cheatgrass, Japanese brome and medusahead.
Much
of the area (45%) is managed by the Idaho Fish and Game, the Nez Perce
Tribe (17%), and the Bureau of Land Management (10%). Some of the land is
private (18%). The Nature Conservancy (8%), Idaho Department of Lands
(8%), and US Forest Service (1%) also manage part of this landscape. All
have different management objectives. Yet all must grapple with
challenging issues, including fire, weeds, and the needs of sensitive and
other animal species. Idaho Fish and Game manages part of the land for
elk, white-tail deer, river otter, pileated woodpecker, black-capped
chickadee, and yellow warbler. The Maloney Creek fire burned about 1/3 of
the landscape analysis area in 2001.
