Work Element Usage Report

Title:

E: 47 - Plant 69 acres of native vegetation.

Description:

Roughly 50 acres will be opened up by the thinning/mastication from this project. After site preparation activities are completed, three different types of planting will occur.
1. Seed with a mix of wildflowers, sedges and rushes will be broadcast
2. Seed with a mix of competitive native grasses in disturbed areas using a broadcaster
3. Plant 22,000 plugs with dibbles or planting shovels roughly on a 3 foot spacing between tree/shrub rows.

Species selection will be based on soil type and potential for inundation and may include: Iris tenax, Juncus patens, Thalictrum sp, Cynoglossum grande, Carex obnupta, and Smilacena racemosa. Grasses to include are Agrostis exerata, Bromus vulgaris, and Hordeum brachyantherum.

All plug planting will occur between January and March while seeding will occur in October or November following thinning treatments. Bareroot and plugs would be planted by contracted planting crews.

Finally, we will plant an additional 19 acres with a diverse suite of trees and shrubs. Approximately 11,000 stems will be planted. Tree and shrub species to include: Acer macrophyllum, Cornus sericea, Corylus cornuta, Oemleria cerasiformis, Populus trichocarpa, Rosa pisocarpa, Salix sitchensis, Spiraea douglasii, Symphoriocarpus albus. Planting will be completed by a sub-contractor, R Franco restoration, who has planted over 400 acres of Greenbelt sites over the past 10-years. Sites are typically planted in February while plants are dormant and soils are moist, thus allowing for root growth to occur prior to summer heat stress. We will use bareroot stock for trees and shrubs with a targeted root to shoot ratio of 1:3. Planters will ensure that the roots have a straight root run and GLT staff will quality check a percentage of trees to ensure they aren't J-rooted. Trees will be planted such that the root collar is planted at the soil surface and there are no exposed roots.

Milestones

Sort	Type	Title	Start	End	Status	Modified By	Modified Date
A	EC	Environmental compliance requirements complete	5/1/2024	4/30/2026	Concluded	Allan Whiting	4/8/2024 5:08:03 PM
		Description: On-the-ground work associated with this work element cannot proceed until this milestone is complete. Milestone is complete when final documentation is received from BPA environmental compliance staff.
B	Obtain plants	Purchase and/or gather plants/seeds	11/1/2024	4/1/2025	Active	Allan Whiting	4/10/2024 2:20:59 PM
		Description: Consider vegetation BMPs for pollinators. Consult your EC lead for additional resources and information on providers of locally adapted native plants/seeds. Native wildflowers will be seeded across 50-acres and will likely include species such as Achillea millefolium, Madia elegans, Thalictrum polycarpum, and Geum macrophyllum. Native grass seed will be used on approximately 16 acres and/or in disturbed areas and may include Hordeum brachyantherum, Agrostis exerata, and Bromus vulgaris. Approximately 22,000 plugs will be installed between tree rows and will include such species as Carex obnupta, Juncus patens, Iris tenax, Artemesia douglasii, and Smilacina racemosa.
C		Establish tree planting locations	11/1/2024	2/1/2025	Canceled	Allan Whiting	4/10/2024 2:20:59 PM
		Description: Mark rows for tree planting by using a tractor with precision GPS equipment. Evaluate soils and hydrology to inform species selection for planting. Consider the presence of herbivores and select species that are more tolerant to browsing pressure.
D		Conduct planting in thinned treatment areas	1/3/2025	3/15/2025	Active	Allan Whiting	4/10/2024 2:20:59 PM
		Description: Roughly 66 acres will be planted across the three sites. About 50 acres will be opened up by the thinning/mastication from this project, and an additional 16 acres will be augmented to provide additional understory diversity. • As appropriate to on-the-ground conditions and plant material availability, use a mix of seed, bareroot material and plugs across the three sites. • AT least 150 pounds of high diversity native seed will be applied by broadcast - we anticipate seeding ~50 acres with a diverse mix of native forbs, sedges, and rushes. We anticipate seeding 16 acres with a mix of resilient native grasses. • Bareroot and plugs will be planted by contracted planting crews. We anticipate planting roughly 20 acres with plugs at a rate of 1100 plugs per acre (roughly a 3 foot spacing between plugs down tree/shrub row alleys.) Seeds or plugs may include: Iris tenax, Juncus patens, Thalictrum sp, Cynoglossum grande, Carex obnupta, and Smilacena racemosa. All plug planting will occur between January and March while seeding will occur in October or November following thinning treatments. Species selection will be based on soil type and potential for inundation.
E		Expand planting in additional floodplain areas.	1/3/2025	3/15/2025	Canceled	Allan Whiting	4/10/2024 2:20:59 PM
		Description: Harkens Lake - Harkens Lake perimeter: The edge of a back-channel approximately 6,000 feet in length) was not planted initially, and has remained dominated by non-native shrubs like blackberry, reed canary grass and poison hemlock. Following the removal of invasive shrubs/forbs contract with a planting crew to plant an approximately 6000 feet stretch with 3 rows of trees and shrubs, with rows spaced ~ 8 ft apart and trees and shrubs spaced every 3 feet, Harkens Lake - South Access Unit: This 14 ac unit was planted in 2018 and has had excellent shrub survival, but the tree layer is missing. Trees will be planted on a 20-foot spacing across the entire unit. Horseshoe lake: This 2 ac unit is the last to be prepared and planted at the site. Following the removal of invasive shrubs/forbs contract with a planting crew to establish 2,400 trees and shrubs in rows (12 foot spacing), installing plants every 3 feet, within the prepared ground. Tree and shrub species to include: Acer macrophyllum, Cornus sericea, Corylus cornuta, Oemleria cerasiformis, Populus trichocarpa, Rosa pisocarpa, Salix sitchensis, Spiraea douglasii, Symphoriocarpus albus. Planting will be completed by a sub-contractor, R Franco restoration, who has planted over 400 acres of Greenbelt sites over the past 10-years. Sites are typically planted in February while plants are dormant and soils are moist, thus allowing for root growth to occur prior to summer heat stress.
