Mechanical Treatments Category

1.1- Grasses, Forbs, and Woody Shrubs

Mowing and Brushing of infested roadsides, early succession fields, and open fields using rotary mowers.

Examples of target species: Sericea lespedeza, multiflora rose, thistles, Japanese stiltgrass, Japanese knotweed, Phragmites, Johnson grass.

50 Acres

1.2- Trees, Shrubs, and Woody Vines

Mechanically cut down invasive trees and shrubs utilizing chainsaws, loppers, and large weed-eaters equipped with brush blades. Example of target species: autumn olive, bush honeysuckle, Japanese barberry, privet, burning bush, barberry, mimosa, princess tree, wisteria.

5 Acres

1.3- Trees, Large Shrubs, and Woody Vines (continuous and dense)

Mechanically cut down invasive trees and large shrubs using mastication heads (e.g. FECON®) on rubber-tracked skid-steer machines equipped with appropriate safety measures. Mastication heads shall be used where other treatments are not practical. Examples of target species: continuous, dense infestations of autumn olive, bush honeysuckle, privet, burning bush, wisteria.

20 Acres

Mechanical and Herbicide Treatment Category: Woody Vegetation

2.1- Trees and Large Shrubs (cut stump) Selective and non-selective herbicides

Treatments involve utilizing hand shears, loppers, and chain saws to sever stems and apply herbicides to stumps. Examples of target species: bush honeysuckle, autumn olive, privet, princess tree, Amur corktree, mimosa, tree-of heaven (limited cases)

30 Acres

2.2- Trees and Large Shrubs (basal spray) Selective and non-selective herbicides

Treatments involve basal bark application of herbicides only. Example of target species: Olives, privets, tree-of-heaven, princess tree, mimosa, and other invasive trees and shrubs.

Acres

2.3- Trees and Large Shrubs (hack-and-squirt) Selective and non-selective herbicides

Treatments involve hack cuts into the connective tissues and herbicide application into the cuts.

Treatments will occur in the growing season only. Example of target species: tree-of-heaven, Amur corktree, princess tree, mimosa, autumn olive, etc.

600 Acres

2.4- Woody Vines (cut stem) , Selective and/or non-selective herbicides

Treatments involve utilizing chainsaws, loppers, and hand shears to sever woody vines and spray the cut surface on the side that emerges from the soil. Examples of target species: Oriental bittersweet, kudzu, wisteria, air potato, Japanese honeysuckle.

5 Acres

Foliar Herbicide Treatment Category: Herbaceous Plants, Grasses, Small Shrubs, and Vines

3.1- Dense Open Land NNIP, Selective and/or non-selective herbicides

Foliar applications utilizing boom sprayers and/or boom-less nozzles mounted to tractors, rubber tracked skid-steers, or UTVs. Infestation areas will be continuous in nature, and areas may be mowed prior to herbicide application. Target species examples: Sericea lespedeza, red fescue, Japanese stiltgrass, reed canarygrass, Chinese silvergrass, bush honeysuckle sprouts, autumn olive sprouts.

50 Acres

3.2- Sparse Open Land NNIP, Selective and/or non-selective herbicides Direct spot application of foliar herbicides utilizing hand-held/ backpack sprayers, or UTV mounted sprayers with a single nozzle application. Infestations will not be continuous within the treatment area. Examples of target species: Sericea lespedeza, Japanese stiltgrass, autumn olive, Chinese silvergrass, reed canarygrass, Japanese honeysuckle, Japanese knotweed.

130 Acres

3.3- Roadside/Trailside NNIP, Selective and/or non-selective herbicides Direct spot application of foliar herbicides utilizing truck/UTV-mounted sprayers, and/or backpack sprayers along designated roads and trails. May include treatments along ORV-only trails, necessitating use of UTV/backpack sprayers only. Examples of target species: Sericea lespedeza, multiflora rose, Japanese stiltgrass, autumn olive, Japanese knotweed.

130 Acres

3.4- Interior Forest NNIP, Selective and/or non-selective herbicides Direct spot application of foliar herbicides utilizing hand-held or backpacks where there is no road or trail access. Examples of target species: bush honeysuckles, kudzu, Japanese stiltgrass, garlic mustard, multiflora rose.

15 Acres

Government Estimate General Information:

The quantities in this document represent the Government’s best estimate of its requirements for the period of contract performance.

Annual acreage estimates are for the entirety of the Wayne National Forest, and not for a single unit. Units in this case denote Athens, Marietta, Ironton, and the 33 Bypass. Estimates encompass the base year, plus four option years, for a total of five years. Acreage distribution on each unit is fluid, and may vary from year to year. For example, in 2017 there may be 1,000 acres of Category 2.3, Trees and Large Shrubs (hack and squirt) contract work available on the Marietta Unit; in 2018, there may only be 250 acres of Category 2.3, Trees and Large Shrubs (hack and squirt) contract work available for the Marietta Unit. The same variability is applicable to the Athens, Ironton and 33 Bypass Units. The WNF anticipates that a majority of Category 2.3 work will occur in 2016 and 2017. This will result in anticipated yearly acreage for 2.3 to total approximately 1500 acres in 2016, and 1500 acres for 2017. Also, a majority of Category 3.2 and 3.3 work will occur along the 33 Bypass, and will occur from 2016 to 2018. Therefore, contracted acreage along the Bypass will be higher in 2016-2018 than the option years of 2019-2020.

These estimates are provided for your information and do not represent actual amounts of work that will be ordered. Individual task orders will be issued against awarded contracts as program needs arise.
