The site is found in Section 15,Township 28 North,Range 1 east(See Figure 1. Site Vicinity Map). The site collectively occupies 250 acres owned by Pope Resources. The purpose of this plan is to identify, address, and mitigate for potential impacts associated with the proposed 54-unit residential subdivision within the property. The subdivision has been designed to establish residential properties which can be developed while maintaining required stream and wetland buffers and setbacks as described in the Jefferson County Critical Areas Ordinance. The project will be mitigated using a combination of management and conservation based techniques intended to preserve the sites overall suitability for local wildlife. The majority of the site proposed for residential use is upland third-growth coniferous forested area, with interspersed patches of red alder. Two lots are proposed within a mature second growth forested area and will include waterfront components adjacent to Ludlow Bay. Management measures proposed include the following: 1. The maintenance of large forested areas for wildlife habitat and passive recreation. Activities allowed would include wildlife habitat enhancement, and the establishment of a trail system to accommodate passive recreation. Specific management techniques include the following: • Reduction of the existing canopy cover within designated areas to a target level of 50 percent. This will be established through the selective removal of overstory trees from a dense interim third growth stand of Douglas fir. The purpose being to promote a more vertically heterogeneous stand structure with more diverse midstory and understory vegetative communities. As the remaining stand matures,the resulting canopy cover will be greater than 70 percent. • Establish target densities of standing dead trees for foraging,nesting,and roosting habitat This will be achieved through the selective topping of live trees and the preservation of trees with defect. This will be done in conjunction with the selective thinning described above.

The establishment of seasonal construction zones within certain areas proposed for development. This is intended to prevent disturbance associated with high noise level construction and residential use to priority bird species during the breeding and nesting period. Conservation measures include the following: • Preservation of important habitat features within the site. Emphasis placed on trees with dead or broken tops, trees with platforms suitable for nesting, trees with exposed lateral limbs, and standing dead trees. • Preservation of all riparian and wetland buffers. • Establishment of a no-touch preservation area in proximity to a bald eagle nesting site. 2.0 SITE DESCRIPTION The site is 250 acres in size. All but two of the 54 proposed residential properties are located within the higher elevation portion of the site, an area historically managed for timber production. The majority of this timber was logged and replanted approximately 30 years ago. The area to be developed is best described as a dense third growth stand of Douglas fir with a sparse understory of scattered sword fern, evergreen huckleberry, and salal. The midstory is sparse in density and comprised primarily of western red cedar and hemlock. Also present, most notably within the northwestern portion of the proposed subdivision, are isolated patches of red alder which range in size from two to eight inches diameter at breast height(DBH). The northwestern portion of the site is occupied by a more diverse and mature forest comprised of western red cedar, grand fir, douglas fir, red alder, and bigleaf maple with a common understory of sword fern, salal, and evergreen huckleberry. The northwestern portion of the site is adjacent to high bank waterfront with moderate to steep gradient slopes up landward. Overall these areas appear less managed and in more of a natural state than what occur within the centrally located portion of the property. A bald eagle nesting site is mapped within this area. The nest has been documented in recent years by the Washington Department of Fish and Wildlife, and its location was confirmed during a field review completed on October 2, 2008. A series of small ravines with forested stream corridors are prevalent throughout the eastern and western portions of the site, while two wetlands have been identified within the eastern portion. All but one stream within the property are mapped as type N (non-fishbearing) streams according to the Washington Department of Natural Resources Water Resource Map. During our September, 2008 field review, all stream channels within the subject property were dry. This being the case, the stream channels are classified as type NS (Non-fishbearing, Seasonal) streams and require a maximum buffer of 75-feet. Wetland areas have been delineated and rated by Wiltermood Associates, Inc.. One large forested wetland along the eastern portion of the property (Wetland A) and one small sloping wetland along Ludlow Ridge Road (Wetland B) have been identified (Everitt, 2008). Wiltermood Associates, Inc has PCt ox 2854, Belfair,WA 98528 cell: 360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com �� a3 � r • Tala Point HMP December, 2008 Page 3 rated the large forested wetland as a Category III and the small sloping wetland as a Category IV. The maximum buffer associated with the Category III is 110-feet while Category IV wetlands require a maximum buffer of 40 feet for Moderate Impact Land Use as described in the Jefferson County CAO. 3.0 HABITAT AND SPECIES The following species addressed in this HMP have been identified according to their local occurrence, habitat requirements, and potential relevance to the project area. These species have been considered based on their state or federal listing status, importance to the ecosystem, and potential to utilize the site. 3.1 Bald Eagle(Haliaeetus leucocephalus)-Federal Species of Concern, State Sensitive Habitat areas associated with Bald Eagle include uneven aged coniferous stands with old-growth components. Nests are typically constructed in larger trees with dead or broken tops providing an unobstructed view of nearby water. Snags and trees with exposed lateral limbs, or dead tops are used as perches and defense stations. Wintering eagle's diet varies from region to region. Eagles associated with the project area are most likely forage on organisms associated with the marine environment. A site map is attached showing the location of the mapped eagle nesting site. Given the importance of the area to bald eagle, site specific management considerations include the preservation of nesting and roosting habitat and the promotion of stand diversity. Portions of the property will be modified to facilitate stand diversity while other areas have been selected for preservation. Additional measures include seasonal construction timing and the preservation of a forested screen for development areas in proximity to observed nesting areas. 3.2 Marbled Murrelet(Brachyramphus marmoratus)- Federal Threatened, State Threatened Marbled Murrelets are typically associated with coastal habitats and nest in old-growth forests. Murrelets may fly as far as 50 miles inland to nest, however the average distance is roughly 5-miles from nest to sea. It is only during the summer breeding months that they are commonly found inland. During non-nesting seasons they live at sea. Murrelets require tall mossy trees in coniferous old growth forests with cavities on thick branches where they can construct a cup nest 20-40 meters above the forest floor. There are no documented nesting sites surrounding or within the project site, the site has potential to eventually develop suitable habitat based on the following; • The site is adjacent to marine waters. • At least 80%of the dominant trees are Douglas fir. • An overall forested area greater than 40-acres is size will be maintained. • Large (32"+ dbh) trees are prevalent within portions of the property, while long term management will focus on the development and preservation of large mature forested areas. PCI 2854, Belfair,WA 98528 cell: 360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Tala Point HMP December, 2008 Page 4 • The majority of the site will be managed to be multistoried with high canopy closure. Large forested areas historically managed as single aged stands will be modified to accommodate a more diversified strata. 3.3 Northern Spotted Owl(Strix occidentalis caurina)- Federal Threatened, State Endangered Spotted owls require a large amount of land for their nesting and hunting grounds; pairs may occupy up to 58 sq. km. They are territorial and do not migrate, but they may shift their ranges slightly in response to seasonal changes. Suitable spotted owl habitat includes trees relatively large in diameter in the stand, multi-layered forest canopy with a moderate to high canopy closure in overstory, midstory, and understory, large, tall, live trees with cavities, broken tops, mistletoe, or platforms of branches capable of holding accumulated organic matter suitable for use as a nest. Dead standing trees and fallen decayed trees supporting abundant populations of prey species are critical to spotted owl populations. The mature forested stand within the project area represents adequate overstory structure for spotted owl. However, the dense third growth stand with sparse midstory and understory strata throughout the majority of the site are not representative of optimal habitat. Management recommendations outlined in section 5.0 will promote midstory and understory development and vertical habitat heterogeneity representative of optimal spotted owl habitat. 3.4 Pileated Woodpecker (Drycopus Pileatus)— State Candidate The pileated woodpecker lives in coniferous and deciduous forests, preferring large, dead trees for nesting. The Pileated Woodpecker digs characteristically rectangular holes in trees to find ants. Pileated woodpeckers seldom use clearcuts, but will forage in clearcuts or shelterwood cuts if substantial foraging habitat is retained. Due to the importance of pileated woodpecker to other wildlife species,this plan has been established to manage large forested areas with target conditions for pileated woodpecker as described in the Washington Department of Fish & Wildlife's Priority Habitat and Species Management Recommendations. The following rational has been taken from the Washington Department of Fish & Wildlife's Priority Habitat and Species Management Recommendations Volume IV: Birds Pileated Woodpecker Dryocopus pileatus Prepared by Jeffrey C. Lewis and Jeffrey M. Azerrad. The pileated woodpecker is listed as a State Candidate species in Washington. The pileated woodpecker is a significant functional component of a forest environment because it creates nesting cavities used by other forest wildlife species (Aubry and Raley 2002a). Their deep foraging excavations provide foraging opportunities for weak excavators, and they accelerate the decay process by physically breaking apart wood and exposing prey that can be consumed by other species (Aubry and Raley 2002a). For these reasons the pileated woodpecker is considered a "keystone habitat modifier" (Aubry and Raley 2002a). The availability of large snags (standing dead trees) and large decaying live trees used for nesting and roosting by pileated woodpeckers has P�gR 2854, Belfair,WA 98528 cell: 360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com (e a3 Tala Point HMP December, 2008 Page 5 declined in many areas as a result of forest conversion (e.g, removal of forest for urban development) and timber management practices (Bull and Jackson 1995,Ferguson et al. 2001). Based on this rational, the overall management of the large forested areas to be maintained at this site is directed at accommodating pileated woodpecker as well as protecting other species of importance. 3.5 Osprey (Pandion haliaetus) - State Monitor Osprey breed along sea coasts, rivers and lakes of coastal North America and winter in the West Indies and Central and South America. They occur along waterways east and west of the Cascade Mountains and are found in western Washington from Bellingham to the Columbia River, and forested portions of eastern Washington. Availability of snags, suitable live trees, or other suitable nest structures near large bodies of water that produce adequate fish supplies are important components of osprey habitat. Ospreys feed almost exclusively on live fish while their nests are generally built near fish bearing bodies of water. High noise level activities associated with construction and landclearing during incubation and early nesting are likely most disturbing to ospreys. Disturbance during this critical period (April 1st-June 30th) can cause adults to leave the nest frequently or for extended periods of time, which can be fatal to embryos and nestlings (Van Doole and Van Doole 1982,Levenson and Koplin 1984). Given the occurrence of nesting sites to the east of the property, measures have been recommended to avoid potential for the proposed development to impact ospreys. The nesting sites are over 600 feet from the property, while all development is proposed greater than 800 feet from the nesting sites. 4.0 PROJECT IMPACTS 4.1 Vegetation Displacement No vegetation disturbance within wetland or stream buffers is proposed or necessary. The lots proposed for development along with associated access roads collectively occupy 60 acres of upland area dominated by a dense third growth stand of Douglas fir. The two waterfront lots proposed will occupy one acre of mature forested area. Guidelines for the two waterfront lots are provided in Section 5.3 to maintain the mature forested characteristics of the lots congruent with residential use. Lots containing stream or wetland areas have been designed to have adequate space to meet stream and wetland setbacks congruent with development of the properties. The continued management of large forested areas surrounding the development is described in Section 5.0 to maintain and enhance the overall habitat value and diversity associated with the site. 4.2 Noise Pollution An increase in noise related to construction activities and long term residential use of the proposed lots is expected. Specific management recommendations are provided for areas within 800 feet of the bald eagle nesting site to avoid impacts to breeding and nesting. Given the existing scale of residential development and use surrounding a large portion of the property, wildlife species associated with much IC PO Box 854, Bec:93VA 98528 cell: 360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com Tala Point IIMP December.2008 Page 6 of the project area have likely become locally adapted to noise associated with residential development and use. It should be noted that the eagle nesting site is in a location more protected from human induced noise and that the strict application of m: :gement .recommendations intended to avoid noise impacts to the nesting site will be important. 4.3 Temporary Increase in Sediment and Turbidity during Construction The development of the proposed property will require site preparation and earthwork activities that will result in exposed soil and potential erosion and sedimentation hazards. Best . 41 tement Practices have been outlined to protect stream and wetland areas being directly or indirectly im•: - by construction activities. The long term maintenance of regulated buffers and large forested areas surrounding the development sites will function to protect long term quality of natural surface water. 4.4 Light and Glare The proposed project will result in an increase in light and glare commonly associated with residential land use. The forested areas to be maintained between the proposed development and critical areas will shield the majority of wildlife habitat from increased light and glare. No im •:. ts to the use of the site by riparian or wetland dependent species are expected to result from light and glare associ: • with this project. Project mitigation includes the preservation of dense riparian and wetland buffers intended to shield light and glare being generated from the residences. 5.0 MITIGATION 5.1 Establishment and Management of Wildlife Zones The primary mitigation proposed to address this development is the maintenance of large forested areas to be managed for wildlife habitat with a passive recreation component. This overall area encompasses approximately 145 acres of the 250 acre site. For the purpose of this plan, it has been divided into three zones according to the geographical location within the project site and zone specific management recommendations. The site plan prepared by RW Thorp has been edited by TWC to show the locations and boundaries of each Management Zone (See Figure 2. Site Map). The general location and zone descriptions are as follows. 5.11 Wildlife Zone A Wildlife Zone A is approximately 52 acres and occupies the western portion of the 250 acre site. The southern portion of this zone (Zone A South) is comprised of a dense third growth Douglas fir forest, while the northern portion (Zone A North) contains a diverse mature forest adjacent to high bank waterfront. An eagle nest is located in the western portion of Zone A North. Four seasonal non- fishbearing streams are located within Zone A as well, one of which contains two forks. The southernmost stream channel is n.. •ped to transition into fish - habitat west of the property. Proposed lots 1-18 border Man: ement Zone A to the east.

It consists entirely of a dense third growth Douglas fir forest with scattered pockets of red alder.There are no mapped nesting sites within this zone. A small sloping wetland is located in the southeastern most corner of Wildlife Zone B. The zone is bordered to the west by proposed lots 19-32 and to the east by Wildlife Zone C,described below. 5.13 Wildlife Zone C Wildlife Zone C is approximately 60 acres in size and occupies the eastern portion of the 250 acre property. It includes a dense third growth Do w.:. fir stand with a forested well:.•.. component. Five seasonal non-fishbearing streams are mapped within this zone. 5.2 Zone Specific Management Although the majority of the identified wildlife zones are densely forested with third growth Douglas fir, the site not been m. .!,.• to facilitate the habitat heterogeneity that would be supported by a more diverse midstory and unclerstory canopy. The process of a natural forest developing such characteristics is best described using the "gap-phase dynamics" concept provided by Meffe et al., 1997. Natural gaps II are created when a forest matures and large trees fall, creating and opening the canopy. The increase in light penetration allows the midstory and understory to develop more rapidly in the gap area where the opening is created. Numerous wildlife species are known to utilize these nutrient rich gaps. As the majority of the proposed wildlife have been planted and managed exclusively for the development of a dense, single age . •' of Douglas fir intended for harvest, an interim management approach is recommended. The goal of this $ . I : I is to facilitate the development of a more diverse forested area by mimicking phased dynamics via selective removal of overstory trees. 5.21 Wildlife Zone A South The s_ •'on of Wildlife Zone A located :•• of the line separating pro• •:.a lots 11 and 12 will be referred to .: Zone A South. Management objectives for this area include the facilitation of vertical •itat heterogeneity, establishment of 'k+,•• .11 habitat features (standing dead trees)at levels, and preservation of riparian buffers. Given the above described objectives,the following management is prescribed for Zone A South; • Selective overstory free removal of 50 percent should be completed to accommodate the development of a mature forest with an eventual canopy closure of approximately 70 percent.No removal of western hemlock or western red cedar present within the midstory should occur. The 70 percent et canopy closure parameter has .geed-according to the recommendations provided in the Washington t,..•-.a r•F air of Fish & Wildlife's Priority Habitat - ' Species , #.t Recommendations,Volume W:Birds,2003. • Snag creation should be completed in conjunction with the selective tree removal described above. It will be accomplished by leaving the bottom 15-20 feet of certain trees being cut.

The size class breakdown recommendations below are provided with the understanding that ability to meet the target size class parameters is dependent on the size and availability of trees. Volume IV: Birds. 2003 Washington Department of Fish and Wildlife 32-6 Size class Foraging snags retained • 2.5-50 cm dbh(10-20 in)(7 snags/ac) • 51-76 cm dbh(20-30 in) (3 snags/lac) • 76 em dbh(>30 in) (2 snags/lac) • No cutting should occur within the regulated stream buffers as identified in the Jefferson County CAO. This is recommended due to the overall steepness of the ravines surrounding the channels and for the purpose of avoiding impacts to wildlife movement throughout these corridors. 5.22 Wildlife Zone A North The portion of Wildlife Zone A located north of the line separating proposed lots 11 and 12 will be referred to as Wildlife Zone A North. This zone consists primarily of a mature forest with both coniferous and deciduous components. A bald eagle nesting site is mapped within the western portion of Wildlife Zone A North. The following management is prescribed for Wildlife Zone A North. Additional recommendations are provided for the residential areas proposed to the east. • With the exception of a building envelope associated with proposed waterfront lot 2, the 400 foot radius surrounding the eagle nest will be preserved as a no touch zone. It is well forested and provides an intact buffer around the eagle nest. No vegetation removal of any type is proposed • The portion of this zone located north and east of the 400-foot radius will be managed to maintain its mature forested nature. For the purpose of establishing a view corridor for proposed lots three through eight selective thinning of overstory trees is proposed. Tree removal from this area will be limited to red alder, big leaf maple, western red cedar, and hemlock. All Douglas fir and grand fir will be marked and left standing. A 300-foot shoreline buffer will be maintained within the entire area north of the nesting site as a no touch zone. • No logging, heavy equipment operation or other high noise level construction is to occur within 800 feet of the eagle nest during the critical breeding and nesting period for bald eagle. This recommendation affects proposed lots six through thirteen and lots 27 and 28. The critical breeding period for Washington's bald eagles begins with courtship in early January PQ 2854, Belfair,WA 98528 cell: 360-620-0618, Office: 360-372-2421 e-mail: boad40@peoplepc.com ( (0 ?. Tala Point HMP December, 2008 Page 9 and ends with juvenile dispersal in mid- to late-August. Therefore, high noise level activity should be prohibited from January 1st to August 31st. 5.23 Wildlife Zone B Management objectives for Zone B include the facilitation of vertical habitat heterogeneity and establishment of important habitat features (standing dead trees) at target levels. The following management is prescribed for Zone B: • Selective tree removal of 50 percent should be done to accommodate the development of a mature forest with an eventual canopy closure of approximately 70 percent. No removal of western hemlock or western red cedar present within the mid story should occur. • Snag creation should be in conjunction with the selective tree removal described above. It will be accomplished by leaving the bottom 15-20 feet of certain trees being removed. This will be completed at a level that achieves an overall target density of 12 snags per acre. The size class breakdown recommendations below are provided with the understanding that ability to meet the target size class parameters is dependent on the size and availability of trees. Volume IV: Birds. 2003 Washington Department of Fish and Wildlife 32-6 Size class Foraging snags retained • 2.5-50 cm dbh(1020 in)(7 snags/ac) • 51-76 cm dbh(20-30 in) (3 snags/lac) • 76 em dbh(>30 in) (2 snags/lac) 5.24 Wildlife Zone C The management objective for Wildlife Zone C is the promotion of vertical habitat heterogeneity, the establishment of important habitat features (standing dead trees) at target levels, and the preservation of regulated buffers associated with wetland and stream corridors. Additional management considerations for Wildlife Zone C are provided to address nesting sites for bald eagle and osprey located approximately 600 feet to the west of the property. The following management prescription is provided for Wildlife Zone C: • Selective tree removal of 50 percent should be completed to accommodate the development of a mature forest with an eventual canopy closure of approximately 70 percent. No removal of western hemlock or western red cedar present within the midstory should occur. • Snag creation should be completed so to achieve a target density of 12 snags per acre using the following size classes. The recommendations below are provided with the understanding that ability to meet the target size class parameters is dependent on the availability of trees.

This is recommended due to the overall steepness of the ravines surrounding the channels and for the purpose of avoiding impacts to wildlife movement throughout these corridors. • No cutting should occur along the easternmost 30 feet of Zone C. This is .recommended to preserve a dense conifer screen between the osprey and bald eagle nesting sites located approximately 600-feet to the east. 5.25 Seasonal Construction Zone Proposed lots 6-13 and 26-28, located in the northwestern portion of the site, are within 800 feet of the mapped bald eagle nesting site in Wildlife Zone A North. All high noise level activity associated with logging, site development, and construction within these lots should be completed outside the critical breeding and nesting period(January 1-August 31). 5.26 View Corridor Clearing Limitations within Designated Lots Proposed lots 6-13 are within 800 feet of the mapped eagle nest, but are also intended to provide territorial views towards the Olympic Mountains. As these lots are located within the 800 foot radius of the mapped eagle nesting site, specific limitations with regards to view corridor opening are recommended. There is currently a 75-foot setback required between proposed building sites and the top of the slope, which, for the most part, represents the transition from the third growth forested area into the mature second growth area containing the eagle nest. The nearest point between the top of slope and the nest is located on proposed lot 9, which is 400 feet. Therefore, the nearest building site as proposed would be 475-feet from the nest on lot 9. Within the 75-foot slope setback area, tree removal should be limited to a 30-foot swath between the buildings and the top of slope. Tree removal is to be limited to red alder and big leaf maple. The areas adjacent to the opened view corridors should be planted with Douglas fir seedlings spaced 10-feet apart to maintain the overall forested nature of the slope setback area. 5.3 Management of Waterfront Lots 1 and 2 The building area associated with proposed waterfront lot two is approximately 350-feet while the building area associated with proposed lot one is 400 feet from the nest at the nearest point (Figure 2). These building areas are located down slope to the southwest, with an approximate 200-foot drop in elevation from the nest.

Construction within these proposed lots will be done so with the intent of locating buildings to accommodate the preservation of as many mature trees as necessary to protect forage,perch, alternate nest, and roost habitat. • All live Douglas fir and grand fir greater than 45" DBH are to be retained. Removal of such trees should only be allowed if it is determined by the local governing authority that they pose a direct safety hazard to residential use of the lots. • If it is determined that removal of potential roosting, perching or alternative nest trees is necessary, a site specific plan will need to identify the individual trees to be removed and outlines protective measures necessary to maintain overall stand structure of the site. • All high noise level construction activity should be conducted outside of the critical breeding and nesting period(January 1 -August 31). 5.4 Best Management Practices For projects such as this residential subdivision, a Construction Stormwater Pollution Prevention Plan (SWPPP) will be required by Jefferson County. Such a plan will include more specificity and detail than what is outlined in this HMP. While all lots proposed contain suitable areas to build while meeting stream and wetland setbacks required by Jefferson County, the following elements should be strictly applied during construction on lots which contain streams, wetlands, or portions of their associated buffers, the purpose being to avoid indirect effects to regulated waters that could result from clearing and construction activities. • Mark Clearing Limits. • Limit construction access to a single location and a properly constructed Stabilized Construction Entrance. • Avoid conducting excavation, filling, and grading immediately following rain events or when wet weather is anticipated. • Install silt fencing between work areas and stream or wetlands to prevent erosion and siltation of waters (See diagram below). • Minimize amount of erodible soils at any given time to the maximum extent feasible. • Stabilize soils following excavation, grading, or backfilling. This can be done using Mulching (BMP C121),Nets and Blankets(BMP C122),or Plastic Covering(BMP C123). • Any cleared area associated with a slope of 3:1 (Horizontal: Vertical) or steeper should be graded to minimize erosion and runoff at the downstream end of the slopes,and runoff should be controlled using Surface Roughening (BMP C130), Interceptor Dike and Swale (BMP C200),and Pipe Slope Drains (BMP C204). • Vehicle maintenance on the construction site should be conducted a minimum of 250-feet from any surface water.

The project will be mitigated using a combination of management and conservation based techniques identified to preserve the sites overall suitability for local wildlife. These techniques entail the preservation and enhancement of wildlife habitat throughout 145 acres of the 250-acre property, through the promotion of vertical habitat heterogeneity; preservation of important habitat features; preservation of important corridors; establishment of a no-touch preservation zone; and creation of important habitat features. The 145 acres has been divided into three zones identified in this report as Wildlife Zone A (further divided into north and south), Wildlife Zone B, and Wildlife Zone C. In addition, seasonal construction timing and development guidelines for specified areas within 800 feet of a bald eagle nest, and Best Management Practices have been recommended to minimize adverse affects to existing habitat while meeting project objectives. I trust this information is sufficient for your needs at this time. Thank you for choosing The Wetland Corps as your habitat consultant. If you have any questions feel free to call.

Onsite Soil Conditions based on Jefferson County Soil Survey Subject Site Soil: Cassolary sandy loam,0 to 15 percent slopes(CfC). The Cassolary series consists of well-drained soils on upland terraces.Slopes range from 0 to 50 percent.Elevation ranges from 50 to 500 feet.These soils formed in reworked glacial and marine sediments.Native vegetation is mainly Douglasfir,western redcedar,western hemlock,red alder,bigleaf maple,rhododendron,salal,huckleberry,and swordfern.Annual precipitation ranges from 17 to 25 inches.The average annual air temperature is 50°F.The above 32°F growing season ranges from about 160 to 260 days,and the above 28°F growing season ranges from about 220 to 320 days.Cassolary soils are associated mainly with Agnew, Alderwood,Clallam,Dick,Everett,Indianola,Kitsap,and Tukey soils.Most of the acreage of Cassolary soils is wooded.The soils are used mainly for production of trees and for small ranches and rural homesites. Whidbey gravelly sandy loam,0 to 15 percent slopes(WhC).- The Whidbey series consists of well-drained,gravelly soils that have a very slowly permeable cemented layer at a depth of 20 to 40 inches.They are on glacial terraces.Slopes range from 0 to 30 percent. Elevation ranges from slightly above sea level to 600 feet.These soils formed in glacial till under vegetation that consists mainly of Douglas-fir,western redcedar,willow,rhododendron,and salal.Annual precipitation is 18 to 30 inches.The average annual air temperature is 50°F.The above 32°F growing season ranges from about 210 to 250 days,and the above 28°F growing season ranges from about 270 to 310 days.These soils are associated with Agnew,Clallam,Dick,Everett,Indianola,and Sinclair soils. Swantown gravelly sandy loam,0 to 8 percent slopes(StB).-The Swantown series consists of somewhat poorly drained,gravelly soils that have a very slowly permeable cemented layer at a depth of 18 to 24 inches.They are on uplands.Slopes range from 0 to 8 percent.Elevation ranges from near sea level to about 600 feet.These soils formed in glacial till under a forest cover of dominantly Douglas-fir,western redcedar,bigleaf maple,red alder,and willow.Annual precipitation is 25 to 35 inches.The average annual air temperature is 50 F.The above 32°F growing season ranges from 200 to 250 days,and the above 28°F growing season ranges from about 250 to 300 days.These soils are associated mainly with Alderwood,Belfast,Clallam,Everett,and Sinclair soils.In a representative profile in a wooded area,a thin layer of organic litter covers the surface.Reaction is strongly acid to medium acid throughout the profile.Swantown soils are used mainly for production of trees and for wildlife habitat.
