5.2 Soils (Soil Type Map)
The US Department of Agriculture in conjunction with the State of Washington has published a soil survey for Grays Harbor, Pacific County, and Wahkiakum, Washington. The following are soil types present on the Wild Thyme farm property.
Buckpeat Silt Loam 30 to 65 percent slope
Douglas fir (Pseudotsuga menziesii) is the primary vegetative species, however natural reseeding is not usually viable and Douglas fir must be planted by hand to avoid canopy dominance by red alder (Alnus rubra). The CMAI for Douglas fir at age 60 is 187 cubic feet per acre per year.
Centralia Loam 8 to 30 percent slope
The reseeding tendencies of this soil type are similar to that of the Buckpeat Silt Loam. The CMAI for Douglas fir at age 60 is 191 cubic feet per acre per year.
Chehalis Silt Loam 0 to 3 percent slope
The primary land use practice on this soil types is agriculture, however timber can be cultivated as well. It shares the same reseeding limitations as the other two soil types.
Soil Characteristics/ Operational Considerations
All soil types on the property limit vehicular traffic in the wet season due to their tendency to yield under weight. I recommend that the landowner continue to keep the roads closed during the winter. If there becomes a need to open the roads during the wet season I recommend they be filled if this becomes economically viable through the SIP program. If a fir overstory is desired, care should be taken to keep primary successional species and brush from overtaking newly planted seedlings in both the Buckpeat and Centralia loam.
