| C | 40 | Install Fence | 2 MacPherson - DeLange Year 2 new exclusion fencing | The subject area is an active restoration project that builds on actions previously implemented by the Skyline Ditch Company to enhance side channel habitat and over-wintering refugia within the fish return channel extending from the Skyline screens to the Chewuch River. The action planned was to improve riparian vegetation along the length of the Chewuch River frontage (1,250 lineal feet) and along a riparian side channel area (MacPherson) to include approximately 1,000 ft. on both sides. The MacPherson side channel runs through properties owned privately (DeLange) and publicly (WA Department of Fish and Wildlife). The public lands are protected under a conservation purchase by WDFW, but the property was not fenced against open range cattle. The project goal was to add significant habitat value to the conservation property and to repair the degraded areas where existing riparian communities have been impacted by past grazing and lack of adequate restoration following fallowing of the land.
Total proposed improvements for the subject area include re-establishing a functioning riparian buffer varying in width from 35 to 100 feet along 1,250 lineal feet on the right bank of the Chewuch River and 2,000 lineal feet of side channel running through the property. This is a multi-year effort. The side channel construction improvements are in progress under a separate project contract.
The fencing element of the project is to include individual plant protection with cages and tubes, clustered plant protection with deer exclusion fencing enclosures, and linear protection fencing designed to exclude cattle. During the first year's treatment, one enclosure / exclosure was constructed and planted (Area A). The area was monitored and assessed for success, and an annual report prepared. During the second year, a new enclosure is planned across the channel (Area B) from the first. Area B was reseeded in Year 1 and has had weed control performed for two seasons. The new enclosure in Area B will be planted with 100 to 200 riparian trees and/or shrubs.
Next, a third treatment site (Area C) is planned under this second year contract. Area C is in the northeast corner of the parcel and was impacted during the Chewuch Dam barrier removal project, and will again be used in the fall of 2008 during repair / modification of the roughened channel structure. Exclusion fencing will be constructed, and riparian plantings established. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| D | 40 | Install Fence | 2 Pigott - Boesel Year 2 new exclusion fencing | Background information repeated from Year 1 contract:
"The Pigott and Boesel / Fodor restoration projects aim to release existing native vegetation and supplement with plantings of native trees and shrubs on both banks of the Methow River. The
Pigott property is located approximately one-half mile south of the Twin Lakes Road turnoff of State Highway 20. The treatment area is within a 20-acre conservation easement held by the Methow Conservancy, and involves a total of 3,200 lineal feet along the river right bank. During project development, strong guidance was received from consulting Tribes and resource agencies expressing concern related to disrupted access resulting from linear riparian fencing of the shorelines. The project was therefore modified to achieve riparian protection through placement of habitat exclosures, rather than linear riparian fencing. The area of treatment (3200 lineal feet) remained unchanged. Exclosures consist of fencing configured to enclose and protect an area of vegetation from grazing and browsing. An exclosure of 500 lineal feet protects about 1/2 acre. The fencing is considered to be portable and temporary. It is anticipated that an exclosure may be in place for 3 years prior to relocating. Therefore, any year 2 exclosure fencing will be new."
Year 1 entailed one enclosure and associated plantings.
Pigott Year 2 information and comments:
Year 2 features will extend protection to additional areas within the project scope to add 1 or 2 exclosures. Exclosure placement will be determined based on observation of emergent native species patterns. This evaluation will determine the relative benefit of using one larger or 2 smaller exclosures. Approximately 150 to 300 feet of fencing, and at least 100 new plantings are anticipated.
It is estimated that 70 to 100 replacement plants will be planted within and near the Year 1 exclosure. Monitoring, assessment, and maintenance in this area will continue. Maintenance includes weekly irrigation, attention to struggling plants, fertilizer where necessary, mowing around plants, weed control, and the like. Monitoring and assessment includes field visits and data collection.
Boesel / Fodor Year 2 information and comments:
Year 1 improvements were limited to a single planting area with individual plant protections. Landowner negotiations continue between Boesel and Fodor to develop a fencing and planting program consistent with the stewardship plan in place for the properties. Proposed work elements for Year 2 are essentially those components of originally proposed work not completed in Year 1. Replacement plantings and more aggressive management in the Year 1 treatment area(s) are anticipated in order to increase success and vigor of riparian enhancement vegetation. No expanded work elements are proposed in Year 2. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| E | 40 | Install Fence | 2 Twisp River Properties LLC - Daudon new exclusion fencing | The Daudon / Twisp River Properties LLC project is a multi-year effort, envisioned to restore native vegetation assemblage to an area approximately 1,300 feet in length along the left bank, and an additional 1,300 feet on the right bank, of the Twisp River, about 9 miles upstream from Twisp, WA. The area is old pasture and consists primarily of perennial grasses, weeds, and a narrow remainder of riparian growth along the Twisp River. The landowner entered into a long-term commitment with Methow Conservancy to regenerate a healthy riparian band along the river by actively re-planting degraded areas and providing browse protection to existing stands of riparian growth.
The first year work focused on the Daudon parcels. The second year will focus on the TRPLLC parcels.
It is proposed to establish 3 new pod-style enclosures, each about 600 lineal feet of temporary fencing. Each would be planted with 600 to 700 new riparian plantings. Assessment of year 1 elements suggests using more drought resistant species toward the outside of the pods. Additional individual plantings (with protection) will be added in the total riparian zone. Plants will be watered with above-ground irrigation in most cases. As the total area of restoration plantings increases, the dedicated well may reach capacity, and drip irrigation may be required to increase efficiency of water delivery. Maintenance of new plantings includes weekly irrigation (and system maintenance), attention to struggling plants, fertilizer, mowing, and weed control.
It is anticipated that no new enclosures will be added in Year 2 on the Daudon properties. Aggressive maintenance of established plantings will maximize survival and success. Management includes weekly irrigation, data collection, attention to struggling plants, fertilizer, mowing, irrigation maintenance, weed control, re-anchoring cages, etc.. Additional riparian plantings will be established within the existing pod enclosure. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| F | 40 | Install Fence | 2 Twisp MSRF new Year 2 exclusion fencing | The total Twisp project is a multi-year effort and proposed to establish a 35-foot wide riparian buffer along 1,200 lineal feet on the right bank of the Twisp River and 2,400 lineal feet (both banks of side channel running through the property). Fencing provides protection to new plantings either through individual cages or clustered plant protection (deer exclusion enclosures). The overall project goals remain constant through the several years of work.
Fences on this property are primarily to protect new riparian plants from deer browse. Deer exist in dense populations in the Methow Basin, especially in the project area. Okanogan County, WA is also an open range county. Landowners who do not want cattle to graze on their property are required to fence them out.
In the second year, one new exclosure pod will be planted in fall of 2008, providing about 1/2 acre of protection for new plantings and naturally regenerating growth. New plantings at this site are irrigated with drip line or small emitters, utilizing well water. 150 to 200 new plantings will be established.
Management and maintenance of first year plantings will continue. Activities include irrigation (and system maintenance), weed control, field assessments, trimming, replacement plantings, etc. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| G | 40 | Install Fence | % Lehman conservancy site 1st year fencing (pasture / exclusion) | The Lehman property is new for the year 2 contract. It is comprised of tax parcel 3422310048. The site is located on the left bank of the Methow River approximately 3.4 miles north of Twisp on the Twisp-Winthrop Eastside Road. The parcel is 222 acres in size and has historically been used for agricultural production and grazing. These activities have occurred both within the floodplain and upland portions of the property and continue today. The floodplain was placed under a conservation easement in 2008. MSRF will partner with the Methow Conservancy, the easement holder, to implement restoration activities. The proposed treatment area lies within the conservation easement.
Year 1 proposed actions:
a.) Restoration of riparian floodplain vegetation - In six key areas, where the property has been heavily impacted by cattle, portable corral panels will be used to construct temporary exclosures to allow naturally regenerating vegetation to grow above grazing and browsing height. Vegetation occurring includes cottonwood, willow, alder, and aspen trees, as well as numerous shrubs. Each area will need protection for several years, and portable exclosures can be moved to new areas of the property as vegetation reaches a level of maturity needed to survive deer browse. An important feature of the proposed action is the procurement of materials (corral panels) for perpetual use on the property for riparian habitat regeneration enhancements. At this time, active planting of new root stock is not planned.
b.) Riparian enhancement - Habitat conditions will be improved by modifying the grazing rotation throughout the property. One pasture fence in the northern portion of the property will be removed and replaced, and one new pasture fence will be constructed in the southern portion of the property. Additionally, to allow natural regeneration of riparian vegetation concurrent with grazing rotation improvements, second and third pasture fences will be constructed in the southern portion of the property. A water line and stock tank will also be installed in the south central area to reduce the pressures on riparian resources. | Chinook (O. tshawytscha) - Snake River Spring/Summer ESU (Threatened), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| H | 34 | Develop Alternative Water Source | Lehman conservancy site water line | The Lehman conservancy site has been extensively grazed by cattle. In order to successfully regenerate the riparian zone, and to lessen pressure on resources, alternate watering location(s) should be provided for cattle. An existing well will be utilized, and approximately 700 feet of 1 1/4-inch PVC water line will be buried. It will supply 3 water troughs within the conservation easement area. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| I | 40 | Install Fence | Satiqua Park - PUD access 1st year exclusion fencing | The Satiqua Park parcel is new in the year 2 contract. It is an 11.5-acre property acquired by Okanogan County through a landowner donation. The park is located adjacent to the Town of Winthrop, across the Chewuch River from the north end of Riverside Avenue (Main Street), on the right bank of the Chewuch River. The PUD access site is 0.31 acres, and is located on the left bank of the Chewuch, upstream and across from the northernmost corner of the Park. The PUD site adjoins the Fulton Ditch diversion repair project. The two pieces served as access points for the Fulton roughened channel diversion project. Prior to the Fulton project rehabilitation, both properties had been extensively impacted by irrigation access and maintenance activities. The riparian restoration project proposes to establish riparian vegetation within these historically impacted areas.
Project objectives will be to establish vegetation within the area defined by the tree height potential: black cottonwood 80 feet, re-establish vegetation in prior scarified abandoned access roads, and establish exclosures to protect / release existing naturally occurring plants and vegetation from deer browse.
First year proposed work plan includes construction of either one large perimeter enclosure, or 5 smaller enclosures, configuration to be determined on-site. Approximately 250 plants will be established, including temporary irrigation and mulching. Wildflower seed will also be utilized to enhance ground cover and diversity of native vegetation. Establishing riparian vegetation in the first year includes field visits and maintenance of plants, mulching, fencing, and cages, as well as weed control. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| J | 40 | Install Fence | % Post conservancy site 1st year exclusion fencing | The Post property is new in the near 2 contract and is located about 11.5 miles up the Twisp River, on the left bank. It was historically a working ranch operation, with irrigated pasture, forage, and hay production. These operations have essentially ceased in the last 10 years. A conservation easement agreement between the landowners and the Methow Conservancy was completed in 2004, which included specifically described protections. In addition, a mutually agreed upon land use plan recommends actions to restore riparian habitat on the property.
Proposed Year 1 actions:
Riparian regeneration and restoration:
A river-side cabin was removed by the landowner from a disturbed open area adjacent to the Twisp River. The shorelines are is in need of restoration. Work includes excavator operations to remove remnant foundation and re-grade the area. The disturbed area is surrounded by riparian habitat and wetlands to the east and west. Restoration will assist in forming a continuous stretch of healthy riparian vegetation along this upper Twisp River corridor.
A "pod" (temporary enclosure) will be created, about 100 feet in diameter, in which native nursery trees and shrubs will be planted among naturally occurring cottonwood, willow, alder, and aspen trees and shrubs. This will allow both new plantings and naturally regenerating vegetation to grow above grazing and browsing height. Plantings will be watered. Wire cages will be used to protect up to 40 new plantings in the area outside the pod.
Adaptive Management:
Plantings will be monitored, using vegetation plots to assess riparian regeneration.
The anticipated outcome of first year work includes enhanced regeneration of riparian trees and shrubs; increased retention of ground cover; added structure along channel, ponds, and wetlands adjacent to the Twisp River; and procurement of materials for perpetual use on the property for habitat regeneration enhancements. | Chinook (O. tshawytscha) - Snake River Spring/Summer ESU (Threatened), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| K | 40 | Install Fence | % Heath Big Valley conservancy site 1st year fencing / plant protection | The Heath site is new in the year 2 contract and is located about 3.3 miles northwest of Winthrop on SR 20. It comprises a high quality side channel and spring-fed pond complex within the Big Valley reach assessment unit of the Methow watershed. The property is protected under a conservation easement. In 2006 and 2007, side channel reconnection project work was completed under with Tributary Fund monies. Culverts and a hard driven crossing were removed, and bridges installed, The site is now ready for riparian enhancement work to commence. Restoration of riparian vegetation will improve spawning, rearing, and overwintering habitat conditions in the newly connected / created side channels. Approximately 300 feet of channel will be treated, for a total of about 0.2 acres including both sides of the channel. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
| L | 47 | Plant Vegetation | 2 MacPherson-DeLange 0.6 mile plant native rooted shrubs/trees or seed | The subject area is an active restoration project that builds on actions previously implemented by the Skyline Ditch Company to enhance side channel habitat and over-wintering refugia within the fish return channel extending from the Skyline screens to the Chewuch River. This is a multi-year effort, and the action planned was to establish a functioning riparian buffer varying in width from 35 to 100 feet along the length of the Chewuch River frontage (1,250 lineal feet) and along a riparian side channel area (MacPherson) to include approximately 1,000 ft. on both sides, thus adding significant habitat value. The side channel construction improvements are in progress under a separate project contract. Also, the portion now owned by the WDFW was not fenced against open range cattle and suffered degradation in past years. .
In the second year, up to 200 additional trees will be planted within the enclosure fence built in the first year (Area A). It is also planned to sow native bunchgrass among the trees established in the enclosure.
First year assessment estimates show that 25 to 50 replacement plants will be needed each year, due to mortality.
New vegetative treatments area planned in two areas. One is across channel from the first enclosure, and will be referred to as Area B. This area was reseeded in Year 1, and has had weed control performed for two seasons. Treatment will include 100 to 200 riparian trees and/or shrubs with plant protection (cages or linear fence), monitoring and assessment of plantings, and continued weed control. The second is in the northeast corner of the property, and will be referred to as Area C. It will also receive about 200 riparian plants with protection, likely an enclosure pod of about 1/2 acre (600 lineal feet), monitoring and assessment, weed control and irrigation.
Establishing riparian enhancement vegetation includes monitoring and management of new plantings during the contract period (being sure there's enough water, weed control, mulching, paying attention to struggling plants, and the like). Once a treated area moves into a second contract, the management will be completed under WE 22 Maintain Vegetation. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |

| P | 22 | Maintain Vegetation | Maintenance / management of previously established enhancement sites (5) | Maintain previously established vegetation through activities that include herbicide application, plant competition reduction (scalping, mats), mowing, irrigation, fertilization, prevention or reduction of animal damage (browse repellents, tree tubes). (Note: herbicides will not be used on this project.)
Four treatment sites were established under the first year riparian contract - Daudon / Twisp River Properties LLC, Pigott / Boesel, MacPherson / DeLange, and MSRF Twisp. All sites were followed by the planting contractor(s) except the Boesel site, where the landowner took care of maintenance. Assessments in 2008 showed clearly that aggressively managed and maintained sites experienced very high survival rates, and the minimally managed site experienced far less survival and vigor.
The anticipated outcome of this work element is the maximum survival and vigor of plantings established under the riparian enhancement program. Actions will ultimately benefit targeted species in a shorter time frame than if maintenance is not aggressive and comprehensive. | Chinook (O. tshawytscha) - Upper Columbia River Spring ESU (Endangered), Steelhead (O. mykiss) - Upper Columbia River DPS (Threatened), Trout, Bull (S. confluentus) (Threatened) | |
