See Attachment C, Plant Schedule for plant container sizes and quantities; and Exhibits D Row Layout Plan for plant locations; and Exhibit F, Details for Plant with Browse Guard Detail.

6.2.18. Watering: Water all container plants, including transplants, within 6 hours following planting, including all woody and herbaceous plants installed from containers for the duration of the Contract. Water as necessary during the IP so that there is continuous soil moisture around each plant. Water more often during very dry, windy conditions to keep plants in good condition. Maintain and repair the irrigation system, as necessary, so that it delivers water to each plant at the frequency and rate specified. For each EP of the Contract provide the following:

EP1 Watering: For container plant basins apply 10 gallons per plant twice a week for a total of 35 weekly events (70 events total) between 1 March and 31 October. For tree transplants, apply 50 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October.

EP2 Watering: For container plant basins apply 30 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October. For tree transplants, apply 50 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October.

EP3 Watering: For container plant basins apply 40 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October. For tree transplants, apply 50 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October.

EP4 Watering: For container plant basins apply 40 gallons per plant every other week for a total of

14 events between 1 March and 31 August. For tree transplants, apply 50 gallons per plant weekly for a total of 35 weekly events between 1 March and 31 October.

6.2.19. Weeding: Weed within 18 inch radius of each plant so that weeds do not compete for soil moisture with the plant. Weeding is to occur and generally timed following the latest rains that generate growth.

For each Establishment Period year (EP) provide the following:

EP1 Weeding: 2 times, around April and July.

EP2 Weeding: 2 times, around April and July.

EP3 Weeding: 2 times, around April and July.

6.2.20. Mowing: Mow all herbaceous growth so that the site is kept in a fire safe condition. Keep a fire suppressor water system, such as a trailered water tank with a motor-generated water hose, onsite and near the work area wherever mowing and other hazardous activities are being performed. Provide the following:

IP Mowing: 3 times, timed and spaced to capture growth throughout the season. Mow entire project site.

EP1 Mowing: 3 times, timed and spaced to capture growth throughout the season. Mow entire project site.

EP2 Mowing: 3 times, timed and spaced to capture growth throughout the season. Mow entire project site.

EP3 Mowing: 3 times, timed and spaced to capture growth throughout the season. Mow entire project site.

EP4 Mowing: 2 times, timed and spaced to capture growth throughout the season. Mow entire project site.

6.2.21. Herbicide Application: The herbicide application program is designed to manage and foster native grass throughout the project site. All application of herbicide must follow the approved Weed Control

Plan. Prevent herbicide overspray and wind drift into non-target and planted areas. Do not spray when wind will carry spray to non-target areas. Do not spray when warm weather can volatilize herbicide and cause damage to non-target areas. Utilize low pressure drift resistant spray nozzles, anti-drift agents, spray shields and any other means necessary to ensure non-target areas are not damaged by overspray and wind drift. To accomplish this, the efforts required herein are to reduce and eliminate the non-native exotic grass and broadleaf herbaceous vegetation and accompanying seed banks while enhancing native grass establishment. Select the appropriate herbicide designed to kill all non-native grasses and undesirable exotic growth, including all vegetative growth that occurs onsite, on the maintenance road, and within the staging area and site edges. Prevent annual grasses from setting viable seed, keep broadleaf weeds under

6” in height. When the staging area is removed and no longer in use, seed its entire area and establish native grass prior to leaving. All spraying must be performed by a certified applicator for the type of herbicide used. Place proper notifications at adjacent public roads/trails two days prior to spraying operations. Provide herbicide product and equipment data to COR for review prior to work. Refer to

Attachment G, Submittal Register and Section 6.2.2.7 of the PWS. Spray applications are defined as follows:

6.2.21.1 “Grass Treatment Herbicide Spraying” is defined as the initial IP site spraying during the installation period that is designed to kill and reduce the existing non-native exotic grass competition in areas where they predominate, and to preserve and foster growth in the existing native grasses areas where they predominate. Leave all vegetation that has been killed on the ground to serve as a BMP to protect the soil as an erosion control BMP. The designated treatment areas are identified in Exhibit E, Novak Grass Treatment Plan.

6.2.21.2 Existing Grass Areas: These areas have abundant amounts of desirable existing native grass that are to remain. The goal is to retain the existing native grass and manage those areas to control exotic grasses and broadleaf weeds. Treat by applying a selective broadleaf herbicides and pre-emergent herbicides. Take care to preserve as much existing native grass as possible. Pre-emergent herbicide use will be discontinued a minimum of 6 months prior to grass seeding.

6.2.21.3 Incorporate the grass treatment areas into the overall herbicide spraying program for row, middles, spot spraying, and pre-emergent spraying after the container plants have been installed and the new grasses have been seeded.

“Rows” are defined herein as the container plant alignments where all herbaceous vegetation 2-3’ out from both sides of the center line are sprayed and killed. This effectively leaves a 4-6’ wide strip “row’ that is void of herbaceous vegetation. Spray all rows with a non-selective herbicide to completely kill all herbaceous vegetation.

Continue this spraying after the grass has been seeded in the Middles and the Grasslands.

Weed growth in the rows shall be kept under 6” in height.

“Middles” are defined herein as the entire area between the rows and includes all areas that are not roads, or rows. Use broadleaf selective and pre-emergent herbicides to control broadleaf herbaceous vegetation and exotic annual grass vegetation in this area, so that the desirable native grasses prevail.

“Spot Spraying” is defined herein as spraying and killing targeted undesirable broadleaf vegetation or non-native exotic grasses. Prior to spot spraying, coordinate the goals with the Contracting Officer. Spray all targeted undesirable vegetation with a non-selective herbicide designed to completely kill the targeted existing vegetation or a selective herbicide to target specific weed and non-native grass species.

“Pre-seed Herbicide Treatment/Spraying” is applied to the Middle areas with an herbicide designed to completely kill undesirable herbaceous vegetation.

“Pre-emergent Spraying” is applied to the entire grass area. Spray with a pre-emergent herbicide designed to kill undesirable weeds. The EP2 spraying must be based on the evaluation and impacts it would have on the creeping wildrye seed. Both establishment year sprayings are to occur after the first fall rains, which is expected to be Nov-Dec.

6.2.21.4 The application quantities for spraying are as follows:

IP Grass Treatment Spraying: : 2 times; time spraying to capture weed growth over entire site

EP1 Spraying: timed and spaced to capture growth.

o Rows: 4 times o Middles: 2 times o Pre-seeding spraying: 1 time

EP2 Spraying: timed and spaced to capture growth.

o Rows: 3 times o Middles: 3 times o Spot Spraying: 1 time o Pre-emergent spraying: 1 time

EP3 Spraying: timed and spaced to capture growth.

o Rows: 2 times o Middles: 3 times o Spot Spraying: 1 time o Pre-emergent spraying: 1 time

EP4 Spraying: timed and spaced to capture growth.

o Rows: 1 time o Middles: 2 times o Pre-emergent spraying: 1 time

6.2.22. Surveying Plants: In the fall of each of the Contract years following plant installation, perform plant surveys to access plant survival and mortality. Surveys must include woody plant survival and vigor assessment, native grass cover percentage, and overall grass cover percentage. Provide a separate survey for each of the areas in N1, S1, S2, and tree transplants identified on the drawings. Include survival rates for each species planted, based on original number planted. Present the results in each of the subsequent annual reports. See Attachment G, Submittal Register and section 6.2.25 for details.

6.2.23. Replacing Dead Plants: At the end of the first and second year establishment periods replace all dead plants using new browse guards, fertilizer, and mulch of like material, size and type as was originally installed. Coordinate species with the Contracting Officer prior to ordering plant material. Since some species are not always readily available at a local nursery, anticipate in advance those species that may need to be replaced and pre-grow the plants so they are at the required container size and ready when needed. Due to unavailability or poor species performance, adjustments to replacement species may be desirable and accepted, provided coordination has been performed with the Contracting Officer in advance and a written approval of species substitutions has been issued.

6.2.24. Preparing Activity Records: Prepare activity records, which include monthly records of work performed during each month of the contract, as-built drawings of all installation work, and a weed control plan for each year of the contract.

Prepare monthly activity records, one for each month of the Contract. Submit the monthly activity record with each invoice, addressing specific tasks billed. Include activities of all installation and maintenance work that is performed throughout each preceding month of the contract. Submit record along with each monthly invoice, within 7 working days following the end of each month.

Each monthly record must not be longer than one page on 8-1/2”x11” format. The monthly record must address a statement of general plant health and site conditions; and specific activities performed of the following: irrigation operations, weed control & types of chemicals sprayed, mowing performed, weeding performed, infrastructure maintenance. During the IP, state all tasks performed and progress made. Include all the monthly records in the annual reports for each year of the contract. Prepare as-built drawings of all tasks performed.

Prepare as-built drawings of project site features. Keep as-builts current and available to the government upon request, and submit with each annual report. Provide hard copies and electronic files of the original site drawings upon request. Accurately and neatly record all information that is uncovered during the course of planting by means of drawings, sketches, details, and notes.

Mark-up and correct using red ink changes. Document the location of the plantings by marking-up a copy of the contract drawings. The exact location of each plant does not need to be indicated on the drawing. However, the exact number of each species planted and replanted must be recorded.

Prepare quarterly update of the Weed Control Plan. Update the weed control plan on a quarterly basis. Determine the starting date of the weed control season, updates must be submitted quarterly starting with the start date of the weed control season. Quarters must be evenly spaced throughout the weed control season. The Update must account for seasonal weather, long term weather forecasts and weed growth rates. Each update must adjust the timing of required weed control activities for the quarter the update is submitted and subsequent quarters. Timing must be adjusted for optimal results from the required weed control activities. In each update, include a discussion of current and anticipated weather conditions and impact of weather on timing of weed control activities for the quarter the update is submitted.

6.2.25. Preparing Annual Reports: Prepare annual reports, one for each year of the Contract. Submit as drafts and receive the Government’s direction and approval prior to printing and submitting the final reports. Document activities and installation, maintenance, plant and site conditions throughout the previous year.
