Foch-Gilttoyees was designated as a class A provincial park on May 20, 2004 following recommendations from the Kalum Land and Resource Management Plan. The protected area portion was designated a year later on March 22, 2005. Drum Lummon Mines and Paisley Point Mines established mineral claims north of Drumlummon Bay in the early 1920’s for extraction of copper, gold and silver. Some mineral claims still exist in this area (adjacent to the north side of the protected area) but are excluded from the park.
Foch-Gilttoyees contains part of a historical First Nations travel route between the Douglas Channel and the Skeena River (the remainder of the route is in Gitnadoiks River Park).
Foch Lagoon is one of the largest and most remote lagoons on the B.C. coast. It includes a highly productive and unique tidal narrows at its entranceway. Because of the heavy tide influence in the narrows the oceanic productivity in this area is very high compared to the rest of the Douglas Channel. The kelp beds that are found in this area support nurseries for a wide array of sea life.
Foch-Gilttoyees protects a regionally significant estuary complex at the north end of the Gilttoyees Inlet. The Gilttoyees Creek and Peechugh Creek estuary is notable for its well-developed inter-tidal flats and relatively under-developed mud flats. Salt-water marsh and meadow communities dominate the inter-tidal flats.
The estuary has very high wildlife values, particularly over-wintering habitat for the Blue-listed Trumpeter Swan, Barrow’s Goldeneye, Harlequin Duck, Surf Scoter, Long-tailed duck and Western Grebe.
