I've marked with highlighter on the maps the area in which we are planning to conduct a volunteer work party on March 30 (Lot 3 only), and the sections of the baseline narrative and plant lists dealing with the invasive plant species occurring on the property. Per the UDC Section 3.6.9.e.2, the work that we are planning to do is considered Type 2 Non-Compensatory Enhancement. This letter and the attached material is intended to constitute the first installment of the required description of enhancement activity that we expect to be undertaking over the next several years at Marsh and Meadows. The long-term goal of this project for JLT is to manage and enhance, with the participation and cooperation of the property owners, the successional recovery of the land in the Conservation Easement from the effects of past agricultural uses, particularly livestock grazing. The assumption is that the open areas will gradually grow back as a mosaic of scrub-shrub and forest, providing improved wetland functions and increased quality and diversity of habitat for wildlife. The basic management and enhancement objectives are: · . suppression and/or eradication of invasive exotic plant species. · replacement with seedling plants of native species already occurring in the vicinity, preferably from seeds and cuttings collected on site. · introduction of native plant species not occurring in the vicinity but appropriate to the site conditions. A timeline for this project has not been defined. The extent of activity will be dependent on availability of volunteer labor and plant materials. However, the effects of the work will be monitored and documented at least annually as part of JLT's routine oversight of the Conservation Easement. The tasks described below will not involve any regulated activities described in UDC Section 3.6.9.b, except Item 7 (destruction or alteration of wetland vegetation). There will be no application of herbicides; nor will there be any use of wheeled or motorized vehicles. The work will be done using hand tools, hand-carried power equipment and wheelbarrows. There will be no significant ground disturbance; nor will there be any alteration of watercourses. The specific tasks identified for the work party on March 30 are as follows: Zones 3-a and 3-c on Lot 3: · Eradicate seedlings of Ilex aquifolium (English holly) by hand-pulling. · Remove mature plants and root systems of holly and Rubus discolor (Himalayan blackberry) by cutting and grubbing. Zone 2-a on Lot 3: · Cut the isolated patches of Phalaris arundinacea (reed canary grass) down to stubble using a weed whacker or scythe. · Stake down black plastic sheetiug to cover the stubble. (Plastic cover is to remain in place for at least one growing season in order to kill the grass roots.) · Hand-pull individual plants of reed canary grass in saturated ground if the root systems can also be pulled out. · Plant seedlings of western red cedar along south property boundary. Zone 2-b on Lot 3: · Plant seedlings of western red cedar along south edge adjacent to the treeline of Zone 3-a. Please let me know if this format for describing the wetland enhancement activity at Marsh and Meadows is satisfactory. It is anticipated that another work party will take place there in October or November. Lots 1, 2 and 4 will be the focus at that time and the tasks will be similar to those described for Lot 3. Would you like us to notify you each time we schedule an activity or would it be acceptable for us to provide you with an expanded version of this letter that could serve as a blanket notice? We would like to settle eventually on a regular program in cooperation with the individual lot owners to manage the weed species. It seems unnecessarily burdensome for us, the landowners, and your office to deal with the paperwork for very minor actions that will ideally be frequently occurring. Feel free to call me at 385-1172. Sincerely, Amy Hiatt, Chair Land Conservation Committee X X x 200.00 ~5'~2'~ X Marsh and Meadows Easement Baseline Vegetation Survey . Summary ...... · ....'. Date: Observers: Attachments: References: Note: April 05, 2000 Amy Hiatt, Karen McKee Plant lists and notes for Zones I through 4 Map of zones and sub-zones (reduced version) Code of habitat types 1997 DNR aerial photo at scale: 1 inch-- 100 feet (used USDA-SCS Soil Survey of Jefferson County Pojar & McKinnon's "Plants of the Pacific Northwest Coast" Guard's "Wetland Plants of Oregon and Washington" WSU's "A Field Guide to Wetland Characterization" The individuals who conducted this survey are mnateur naturalists, wetlands delineators. as basis for the Zone Map) not professional No archival or oral research has been conducted on historic land-use of this particular property. The assumption is that the bottom lands throughout Beaver Valley were among the earliest areas in the region to be cleared for agriculture. The land was probably logged off ca 1880-1900, the stumps gradually removed and ditches installed to i~nprove drainage. The land has probably been used primarily for pasture. It is not known whether any of it has ever been cultivated. The ca 1954 aerial photograph used as the base for mapping of the Soil Survey shows more open land than presently exists. It is likely that the wettest areas have been least grazed, either because of fencing or lack of easy access by livestock, and have slowly returned to forest. There remain a very few large, charred and decayed stumps and suags itl the area where most of the larger living trees are located. No samples have been taken to positively date any of the trees on the property, but none appear to be older than about 100 years. In the case of the Douglas-firs, this judgement is based on the relatively thin bark at the base of the trees. In the case of the cedars, the judgement is based on size. Tile largest trees on the property do generally appear to have grown up in tile open. They were perhaps left standing to provide shelter for livestock or because they were on ground unsuitable for agriculture such as the knoll in Zone 3-b. The wetlands on tile property are extensive and varied. Zone 2 contains the open wetlands. Zones 3 and 4 contain forested wetlands with some upland areas. The open wetlands do not appear to have much diversity of plant species at the present time. Juncus effusus and possibly Juncus balticus are the dominant plants other than grasses. But, since livestock grazing will no longer be permitted, the diversity should gradually increase as sedges and other herbs and shrubs re-introduce themselves. This process could be accelerated by planting, but it seems that tile greater challenge as far as enhance,nent activities are concerned is the control of invasive, non-native species such as Himalayan blackberry, Canada thistle and reed canary grass. These three species are present on the property now but have so far not become widespread. Tile forested wetlands have a moderate diversity of plant species and appear to provide significant habitat for birds and small ~nammals. At least a half-dozen old bird nests were observed and the following birds were heard or seen: winter wren, black capped chickadee, red-wing black bird, robin. Deer tracks aud coyote scat were seen. The predominant ground cover in the less shaded areas of Zone 4 is creeping buttercup, but it yields to extensive carpets of youth-on-age, bleeding heart, false lily-of-the-valley and foam flower in the deeper forest. The abundance of moss and the occasional licorice fern growing on an alder indicate that the entire area remains moist throughout the year. Skunk cabbage is abundant around the edges of Zone 4 in very wet, spongy ground. The predominant understory plant through much of Zone 4 is sahnonberry, particularly in association with alders. A number of unusually large Pacific crab apples call be found ill the vicinity of the oldest conifers, perhaps marking the edge of an area that was formerly more open. English holly has become well established in Zone 3 and the western part of Zone 4-d, but could be controlled by hand weeding of the small seedlings and grubbing out of the larger plants. This plant survey was conducted in early spring, before most deciduous trees and shrubs had leafed out. It is likely that many more species would be added to each of the zone lists after another visit later in the spring or in early summer. Also, as mentioned ill the notes for Zone 3, that area has uot yet been surveyed ill detail. Recomme~dations for fm'ther action: Complete the plant species inventory for Zone 3. Continue to supplement the plant and animal inventories for all of the zones during annual monitoring visits and at other times as appropriate. .. Research and record the land-use history of the property through interviews with Bruce Porter and other individuals who have knowledge of the area. .. Implement a program in collaboration with the landowner(s) for control of invasive non-native species, targeting English holly, Hilnalayan blackberry, Canada thistle and reed canary grass. .. hnplement a program in collaboration with the landowner(s) for enhancement of plant diversity and hydrology, particularly in Zone 2.

According to the USDA-SCS Soil Survey, the soil type is Kitsap silt loam. The ca 1954 aerial photograph used in the Survey shows that this area was cleared, probably pasture. Conifers were planted across the area in about 1995; several firs and cedars have survived. The northern boundary of the area is an old fenceline with a hedgerow developing along it. The deciduous trees and shrubs listed above are located there. The rest of the area has a dense cover of mixed grasses with a few other herb- aceous species scattered throughout.

The USDA-SCS Soil Survey describes a variety of soil types within the zone. The historic pattern of land uses and the zone boundaries delineated in this report both correspond consistently with the soil types. Zones 2-aand 2-ccontain Belfast silty clay loam (wet variant) and Alderwood, Everett and Swantown gravelly sandy loams. These areas are noticeably higher and drier than Zone 2-b which contains McMurray and Mukilteo peats and Semiahmoomuck. Zone2 appears to have been used as pasture and perhaps hayfield until the mid-1990s. The ca 1954 aerial photograph used in the Soil Survey shows that Zone2 was cleared grassland. The predominance of juncus and grass species is indicative of grazing activity. There are signs that sedges, shrub species such as cornusstolonifera and spirea douglasii, and a few willows are beginning to spread into Zone 2 from the adjacent woodlands. This natural pattern has been enhanced by the planting ca 1995 of dozens of Sitka spruce along the woodland edges. There is evidence of old ditching at theNend of Zone 2-b. Another ditch runs along the Sedgeof Zone4-d. Aroad trace lies parallel to and Wof this ditch. Acrossing of the main stream appears to have been located near this point.

The list above results from a quick walk through the area in late winter. The expectation is that Zone 3 has very similar vegetation to Zone 4. The tree species and ages appear to be about the same. There is, however, more variety in soil types in Zone 3. According to the USDA-SCS Soil Survey, Zone 3-a contains Semiahmoo muck and McMurray/Mukilteo peat. Zone 3-b contains Alderwood gravelly loam. Zone 3-c contains Everett and Swantown gravelly loams. Zone 3-b is a knoll with an uneven surface and an unusual number of large rocks protruding from the ground. The knoll is covered with a grove of large Iow-branching cedars and a few large Sitka spruce. Around the edges of the grove are many young Sitka spruce planted ca 1995. Zone 3-c contains a mammade pond built ca 1960 Drainage from the pond is directed across the open area in Zone 2-a through a ditch roughly parallel to the S property line. It disperses into the forested area in Zone 3-a and eventually jOins the main creek.

The sub-zones identify areas with different distributions of tree species and ages. Zone 4-a borders the creek and extends along the ditch and fenceline at Embody Road. Most of the trees in Zone 4-a are deciduous. A group of standing dead alders is located near the N end. Alder is the dominant tree in Zone 4-b, with a scattering of young cedars. Zone 4-c is an almost pure stand of alders, not as large as those in Zone 4-b. The dorninant understory plant in both Zones 4-b and 4-c is salmonberry. Zone 4-d contains a mix of conifers and unusually large alders. The older cedars and firs have Iow branches indicating that they grew up in the open. A group of Sitka spruce (approx. 18" dbh) is located near the SW edge. A few large charred snags and stumps are scattered in the same area as the largest living trees. In the W corner of Zone 4-d is one small area of relatively recent blow-down, affecting a half-dozen medium sized cedars. No stumps of recently cut trees were observed. The USDA-SCS Soil Survey shows that Zone 4 contains Mukilteo peat and Semiahmoo muck. The ca 1954 aerial photograph used in the Survey shows that the E half of Zone 4-d was unforested, apparently meadow or grassland; Zone 4-c probably contained shrubs or small trees. The tallest trees were along the SW edge of Zone 4-d. in the same location as the oldest and largest trees are today--in a belt ' ~:~-"~'~ !Habitat Type Codes (Jefferson Land Trust) 'I -- r Woodlands .......... 1: Coniferous Forest - dominated by coniferous trees ....... 2 Deciduous Forest- dom!hated ~¥ dec!,(~u°us trees .................................. ~' Mixed Forest- mix of coniferous and..dec!.d~O.U~.:,!,r.,e,e...s. .......................................................................... :resh Water Habitat _ 5 Creek/Stream ..... 6 Bo.g.- r.efe[dng to ;l~'l~agnum ............... ."." .i ......
