On April 28, 2008, the Blue Mountain and Kanaka Creek Conservation Group submitted a complaint to the Forest Practices Board. They asserted that rare wildlife species and domestic water sources are being damaged by motorized recreation users in the Kanaka Creek watershed near Maple Ridge, including Kathryn Creek. The Kanaka Creek watershed area has sensitive amphibian habitat containing both red-legged frogs and coastal tailed frogs. The area may also contain Pacific water shrews. All three species are designated as ‘species at risk’ under the Forest and Range Practices Act (FRPA).
