E. SankelaY An inventory of the forests of Grays Ha.rbor County, Washington, was first made by the Forest Service in 1932 as a part of a national survey of forest resources. Results of this inventory were summa rized in a statistical report issued in 1954. In the fall of 1957 the inventory was brought up-to-d ~ te through field examination and office recompilation. Adjustments were made for all changes in forest types and merchantable timber volume due to depletion by cutting and fire, the restocking of deforested cutover and burned land, and tr&nsfer of ownersltip of forest land since the original inventory. Also adjust ments due to more intensive fi..eld work, changed economic standards, and other factors were made. Statistics resulting from the 1957 re vised inventory are presented in this report which supersedes the one issued in 1954. Methods used in the survey .and detailed definitions of types are described in an expl&12~tory text entitled "The Forest SUrvey of the Douglas Fir Region",E/ which should be read in connec tion with this report. Location and Description of County Located in the west-central part of Washington, the county bor ders on the Pacific Ocean f9r approximately 50 miles north and south and extends inland from 50 to 50 miles. It is roughly L-shaped and has a total.land areu. of 1,225,510 acres. In the southwest part lies Grays Harbor ~fter which the county was named (figure 1). Y The field and office wol'k of the forest survey of Grays. Harbor County was done by Wm. E. Sankela, P.A. Briegleb, M.J. Lauridsen, Claude Kerr, B.C. Baker, A.W. Hodgman, E.D. Buell, Paul Logan, E.J. Hanzlik, B.H. Pe.yne, D.J. Kirkpatrick, and P.N. Pratt. g/ Oregon and Washington were divided ·for purposes of the survey into two regions, (1) the Douglas fir region, consisting of the.t purt of both St11tes west of the summit of the Ce.scade Range, and (2) east ern Oregon nnd eastern Washington, that part of both States east of the surnrni t of the Cascc.de Rane;e. Regional reports will be is sued which will present and discuss findings for each region as a whole. The regional reports will include nn interpretation of the forest survey dc.ta as related to other economic do.tn. nnd c:: com prehensive analysis of the regional forest situation from both :::.. physical and .:m economic stc.ndpoint. The bulk of the county is Cl.ra:i.ned by rivers that &re tribut.cry to Grays Hc.rbor. The Chehalis, the largest river, enters the county in the extreme southeast ·~oruer e.nd flows northwesterly to Grays H.:,rbor to drain most of the southern pl'.rt of tne county. It is nnviea ble to river boa ts fOl~ & distarwe of <"l::. out 2:S l'liles nbovB its mouth.

Nortn River in the extrerJe southern part of the cour.ty is tributary to Will<-pa Hn.rbor in PD.cific County. Th'.::! topobrap.hy varies from rolling to :nou."ltD.inous terrain.

Address Director, Pacific Northwest Forest ~md Ronge Expe1,in0nt Station, 42:5 U. S. Court House, Portland, Ore€,:. - ·~~ - In the 1937 inventory u total of 1,149,485 acres was classified as forest land. This is approximately 94 percent of the county's total land area. Saw-Timber Type[ Coniferous forest types of saw-timber size (20 inches or more d.b.h.) occupy a total of 438,180 acres or about 38 percent of the total fore::st 1.2Ild area. Western hemlock stands (type 14) occupy 235,160 acres or over one--half of the total area of merch.2Ilto.ble types. This type covers nearly all of the virgin forest area thnt lies southec.st of Grnys Harbor, predominates on the lower slopes of the Olympic Mountdns in the north ern portion of the county, and occurs as sm:J.ll scattered stands ?tlong the co n.s t immedi.:.tely north of Grays Harbor. These l.s.tter st~mds and some of those in the southern portion have been selectively logged; in ::pproxime.tely 24 percent of t he totD.l crea of the type the high-quality trees havo been removed. Western red cedar (type 17) ranks second in area of saw-timber types. It covers a total nroCJ. of 91,795 acres and is the predominating type throughout nearly ell of the Quinault Indian Reserv2tion where it occurs on poorly druined soil of low site quality. Smaller c.reas of this type occur on moist site:.; in the Olympic Mountains and o.long the coast. Old-growth Douglas fir, over 40 inches in d.b.h. (type 6), once the predominant typt; over a large portion of the county's area, now oc cupies a total area of only 49,900 acres. Tho most ext8nsive <!lrea of this type is in the upper Vlynoochce nnd Wishkah River drainages. Other small t:t reas of the type remain in the southern part of the county. Fir-mountain hemlock stands (type 25) are limited to the north-· eastern part of the county wher.J t~ cy occupy en area of 59,615 acres of the upper slopes of the Olym~ic Mountains. Silver fir is the principal species in the type and compriGes the majority of the merchantable vol ume. Associated species include mountain he:mlock, western hemlock, Alaska cedar, western v:hite pine, ond alpine fir. Sto.nds of old--growth Sitkn spruce (type 11), small old-growth Douglas fir (type 7), nnd second-growth Douglas fir (type 8) occupy a relatively small acreo.ge in the county.
