Between the 1970s and 2009, logging was undertaken in the watershed. There are old roads and trails throughout the Conservancy, many of which are now overgrown.
First Nations have a long history of use of the area. The high levels of use are a result of the high salmon and wildlife habitat values centered on Hanna and Tintina Creeks, and the resulting high subsistence and cultural values. The area is currently used for trapping, hunting, fishing, and collecting berries and medicinal plants. It was also the centre of a major trade route, with trails going north, south, east and west.
The floodplain of lower Hanna and Tintina Creeks is a very important ecosystem in the region. The area contains very valuable sockeye salmon spawning, rearing and overwintering habitat, is a critical grizzly bear feeding area because of the salmon, and valuable moose winter range.
Rare ecosystems known to occur in the conservancy include four wetland ecosystems: mountain alder, red-osier dogwood, lady fern low bench floodplain (Fl02, blue-listed), Sitka sedge, peat-mosses fen (Wf51, red-listed), scheuchzeria peat-moss (Wb12, blue-listed) and shore sedge, buckbean, peat-mosses bog (Wb13, blue-listed).
Willow-thicket and riparian ecosystems were identified by First Nations as sensitive to development and as important habitat for moose and other wildlife.
Fish species recorded in Hanna and Tintina Creeks include sockeye, coho and chinook salmon, bull trout (blue-listed), Dolly Varden, steelhead, rainbow trout and prickly cculpin. Of these sockeye salmon are by far the most abundant. The Hanna and Tintina watersheds are provincially significant for grizzly bear habitat values, due in large part to the salmon runs. The lower Hanna and Tintina creeks provide for moose winter range and Hanna Ridge provides for mountain goat habitat.
A number of fur bearers reside within the conservancy including marten, fisher (blue-listed), wolverine (blue-listed), ermine (weasel), mink, lynx, fox, coyote, wolf, muskrat and beaver.
