Discussion
In an ecological study of competition in subalpine meadows in Deer Park, Olympic National Park, Washington, R. del Moral (1983) found that Luetkea pectinata occurred in colder sites, with lower relative drought stress, and moderately low net above-ground productivity (115 and 185 g/m2/yr). Although not focused on L. pectinata, detailed work by del Moral evaluated microsite and microclimatic variation where L. pectinata is able to survive and may be useful in evaluating other sites where L. pectinata forms clonal carpets or where it is a component of a plant association. In contrast to the subalpine studies by del Moral, B. McAvoy (1931) presented a detailed study of plant associations in the Bella Coola Valley, British Columbia, from tidal flats to the alpine zone. She described some of the associations in which L. pectinata occurs, and the range of habitats in which it can occur within a limited geographic region.
At higher latitudes (48–65°), Luetkea pectinata ranges from sea level on rocky substrates to open tundra, high elevation alpine tundra, heaths, and other rocky moist habitats with well-drained thin soils. At lower latitudes (40–50°), the southern end of its range, it occurs at or above timberline in mesic to wet forest openings and edges of tree clumps, meadows, heathlands, open rocky slopes and mossy seepage areas, and in subalpine and alpine zones, often forming dense carpets or mats. Plants of L. pectinata appear to be shade intolerant.
