DENNETT SOILS Location and Extent : Dennett soils are common at the higher elevations of the Coast Mountains . Althoug h only about 15 ha of pure map units are classified, numerous soil complexes dominated by Dennett soils tota l 7060 ha. The complexes are mostly with Sayres, Lions, Palisade, Hollyburn and Whonnock soils and Roc k Outcrop and Talus land types . Topography and Elevation : Dennett soils are strongly rolling to very hilly with slope gradients ranging fro m 20 to over 70 percent . They occur mostly above 700 m elevation and usually occupy the tops and upper slope s of ridges and knobs in the mountainous landscape . Parent Material and Texture : Dennett soils have developed from organic forest litter, at least 10 cm an d usually between 15 and 30 cm thick, over bedrock . The deposits are mainly well-decomposed (humic) material . A thin layer of mineral soil, up to 10 cm thick, is sometimes present immediately above the bedrock . Soil Moisture Characteristics : Dennett soils are well to moderately well drained . They are rapidly perviou s and have a low surface runoff although substantial lateral seepage along the top of the subsurface bedrock i s usual, especially where the bedrock is massive . Water holding capacity of the organic material is very high . General Soil Description : Dennett soils generally consist of about 1 to 4 cm of raw to partially-decomposed needles, twigs and leaves underlain by about 20 cm of dark reddish brown, well-decomposed, humi c material that is matted to amorphous and contains variable amounts of mycelia . Underlying this is bedrock , usually granitic . A thin (less than 10 cm) layer of grayish, leached sandy material sometimes occurs betwee n the organic material and the top of the hard bedrock . Soil reaction of the organic material is extremely acid . Soi l Classification is Typic Folisol . Commonly Associated Soils : Sayres, Palisade and Hollyburn soils and Rock Outcrop and Talus lan d types usually occur in close association with Dennett soils, either in soil complexes or in adjacent ma p polygons . Sayres and Hollyburn soils differ from Dennett soils by consisting of 10 to 100 cm of mineral soil ove r bedrock while Palisade soils have developed from colluvium deeper than 1 m . The Rock Outcrop land type consists of exposed rock at the land surface while the Talus land type is composed of actively accumulatin g stones, boulders and gravel on and at the base of steep, rock faces . Vegetation : The vegetation on Dennett soils is generally coniferous, consisting mainly of Pacific silver fir , western and/or mountain hemlock and yellow cedar, often in an open stand . There is usually also a relativel y dense ericaceous shrub layer and soil surface moss cover. Rooting is limited to the depth of the underlyin g bedrock and a layer of concentrated roots is often present on top of the rock . General Land Use Comments : (1) Dennett soils are unsuitable for agricultural or urban uses because of very steep slopes and shallow depths to bedrock . (2) Forest production is poor to moderate (usually betwee n about 2 .8 and 5 .5 cubic metres of wood/ha/yr) and is limited by adverse, high elevation climatic conditions an d shallowness to bedrock. During forest harvesting, extreme care must be taken to ensure the shallow organi c capping is not removed or destroyed . 66
