Photo description

Additional Comments

Tasha Creek flows from the Fishlake Hightop Plateau at 11,900 to 9,000 feet where it enters the broad Sevenmile Creek valley on the Fishlake NF.

This section of Tasha Creek (above Forest Road 640 and its confluence with Sevenmile Creek, has numerous abandoned beaver dams and beaver ponds and meadows. The last dam in this set of photos is an active beaver dam, and the dam immediately below it shows signs of beaver activity. However, beaver will not be able to stay long or as a large family here, despite willows at the edge of the pond (food), and aspen beyond (building materials) because cattle are browsing the willows severely. People say “beaver eat themselves out of house and home” (which is not always true; in some streams, beaver are present for a long time,with willows, cottonwood, and aspen regenerating). In the case of the active dam on Tasha (see photos below), the cattle are eating beaver out of house and home.

Also included in this set of photos are pictures inside and outside of the Sevenmile Exclosure along Sevenmile Creek and adjacent to Road 640. Astounding differences.

Upper end of pond trampled. Vegetation low—a sedge?

Beaver dams establish ecological settings for species. Without beavers we lose the opportunity to create wetlands communities; lose potential riparian habitat. If this dam fails and get wet meadow— How common are wet meadows? Wet meadows ecologically important.

An opening in a spruce fir forest is a rarity; relatively unique feature in this landscape.

Curious to know why beaver gone—

2197

Upstream meadow w/ the creek—little dams--inactive

What habitat is being eliminated by the grass and shrubs being shorn so short in this meadow?

2198

Note difference in vegetation height where it isd accessible to livestock (left) and not out in the pond’s “islands”.

2199

Very few forbs. Rhizomatous grasses browsed to 2-3” tall

Willow only 16” tall in meadow
