Several rare ecological communities are found on the conservancy. For example, Jimmy Wilson Creek empties into Skedans Bay where it forms a locally rare Sitka spruce – Pacific reedgrass (Picea sitchensis – Calamagrostis nutkaensis) estuarine association (blue listed) that is unique to the east coast of the archipelago.
Ḵ’uuna Gwaay Conservancy contains fish-bearing streams that are known to host sockeye salmon, coho salmon, chum salmon, pink salmon, steelhead, Dolly Varden and cutthroat trout. The conservancy’s recommended marine area is highly biologically diverse, and supplied five percent of the Haida Gwaii Rockfish Fishery between 1995 and 2004 as well as two percent of Haida Gwaii’s Geoduck Fishery. The foreshore and marine environments also provide high value habitat for important marine species and include six seal haulouts and three Stellar sea lion haulouts.
Bird Studies Canada has identified the area as an important bird area. The area hosts numerous listed species including 18 known Peregrine falcon (blue-listed) nesting sites, and important foraging habitat for Pelagic cormorants (red-listed), Ancient murrelets (blue-listed), tufted puffins (blue-listed), and marbled murrelets (red-listed). Within this conservancy, Northern goshawks (laingi subspecies – red listed) and marbled murrelets (red listed) may inhabit areas of old growth forest.
Several archaeological sites contain a number of recorded cultural values. These include at least 12 known culturally modified trees, subsurface shell middens, a habitation cave, a petroform, lithics, human remains and fire broken rock. Many of these areas have not been inventoried thoroughly which indicates that the conservancy likely contains many other unrecorded cultural heritage and archaeological sites.
The cultural heritage values in the conservancy include opportunities for the ongoing continuance of Haida culture through traditional use of the area. Some examples of traditional use within Ḵ’uuna Gwaay Conservancy may include monumental cedar and cedar bark harvesting, seaweed harvesting, medicinal plant harvesting, hunting, fishing, trapping and food gathering. The conservancy also provides a place for the physical expression of culture through monumental art such as totems or establishment of traditional style infrastructure such as longhouses.
