RE: GRANT APPLICATION FOR PHREATOPHYTE CONTROL PROGRAM (TAMARISK AND RUSSIAN OLIVE REMOVAL ATTEST: Jdo'11 BOARD OF COUNTY COMMISSIONERS Weld Cou y le to t Board WELD COUNTY, C•LORADO Dep ty Clerk to the oard rbara Kirkmey-r, Chair E � NOV 0 82015 11610Z0 i5-36 7 Colorado Water Conservation Board Invasive Phreatophyte Control Program Application Form Basic Application Criteria In 2010, the counties of Denver, Adams, Boulder, Larimer, Logan, Morgan, Sedgwick, Washington and Weld along with various entities within each county entered into the South Platte River Watershed Management Area Agreement and created the Platte Invasives Endeavor Plan or PIE Plan. This plan can be referenced at www.weldweeds.orq. The PIE Plan outlines the need for control of the phreatophyte species within the overall South Platte Watershed including the smaller drainages, such as on the Little Thompson and Big Thompson Rivers. The plan also covers the best management practices that will be used to treat tamarisk and Russian olive trees based on the Tamarisk Coalition's recommendations. The partners agreed to and outlined, in the PIE Plan, that the tributaries would be addressed first before the main channel of the South Platte River. This would provide the ability to have a strong support system in place for the removal of the Russian olive and tamarisk trees in smaller, more manageable stretches within each of the counties before the South Platte River was addressed. Lastly, there would be less reinfestation of the South Platte River if the tributaries are free of Russian olive and tamarisk trees before work was begun on the middle stretches of the South Platte River. These steps have been accomplished in Weld County. In 2010 the Cache La Poudre River was addressed and is finishing the five years of maintenance. In 2014 the St. Vrain River was addressed and is beginning its first of five years of maintenance. The Big and Little Thompson rivers have had work done on them in 2011/2012. Mop—up work on these rivers is needed. Along the South Platte River mostly, there are sporadic infestations of tamarisk near the river. These become more prevalent around inactive gravel pits. There have been good results in controlling some areas of the tamarisk trees by educating private landowners and continued efforts by county weed staff to be sure the landowners are addressing the problem. By continuing the education process and providing removal assistance it is possible to have the tamarisk trees eradicated in the next 10 years. This will be done primarily by using the cut stump method of treatment. Russian olive trees are more widespread along the Little Thompson, Big Thompson and South Platte Rivers and mixed in with desirable vegetation. The presence of the trees usually occurs at an elevation of approximately 6500 feet and lower. Russian olive removal along these areas will be a long-term task with light to heavy infestations along the drainages. Many of the Russian olive trees are on privately held properties, which require educating landowners on the importance of removal and offering financial incentives to remove the trees. Therefore, the best strategy to remove Russian olive trees along the riparian areas of the drainages is to work closely with municipalities and governmental agencies, to demonstrate to private landowners the positive impact on the environment the removal of Russian olive trees has. Eradicating Russian olive trees from the South Platte, Little Thompson and Big Thompson Rivers will require a cut stump treatment to achieve effective control of this species. This practice will also have the least impact on the surrounding native vegetation and wildlife. An integrated pest management (IPM) plan will be utilized in the removal of the invasive phreatophyte trees. There are no biological control options for Russian olive trees; however, if an option existed it would be utilized. The biological control option for tamarisk trees is available. However, the number of tamarisk trees that exist along these rivers is not a large enough population to sustain the beetle. Also, the beetle does not do well at the longitude and latitude of these rivers. A purely mechanical option is not the best choice for treatment. The removal of the invasive phreatophyte trees with a backhoe or other large piece of equipment, used in mechanical methods, disturbs the most soil surface and opens up the ecosystem to other weed problems and erosion that can deposit sediment into the river. Consequently, the best control method to utilize is a cut-stump treatment. In the cut stump treatment process the trees are limbed with the tree trunks cut as close to the soil surface as possible. Chemical will be applied to the cut stump within a minute of the final cut being made. The cut material will be chipped and a resource to utilize the chips will be pursued. Discussions are ongoing with the town partners to use the chips as mulch in their landscaping projects. Research is also being conducted to utilize the chips as a light soil amendment when re-seeding disturbed sites or sand soils with limited organic matter. One of three chemicals - Rodeo, Habitat or Garton 3A -will be used to kill the remaining root system of the Russian olive and tamarisk trees. All of these chemicals have an aquatic label for use up to and at the edge of water. The chemical used will be determined by the site. Most sites will be treated with Garton 3A. However, for sites that are the most sensitive or slated for revegetation work, Rodeo will be used. Habitat will be used on the sites that are difficult to access, which limits the amount of re-treatments that can be done. Any secondary noxious weeds that are detected throughout the active project and monitoring phase of the grant will be controlled by the landowners. This will be handled through the normal Weld County Weed Division Code Compliance program that is based on the State Noxious Weed Law. As the Weed Division Supervisor makes the inspections to check on the progress of the project, any other noxious weeds identified will be addressed with the landowner and terms arranged to bring the property into compliance. Each site where Russian olive and tamarisk trees are removed will be evaluated for the amount of restoration and revegetation that is needed. This work will be done by the West Greeley Conservation District. Sites that have a good amount of native riparian plants already established and the invasive phreatophytes in limited numbers will receive passive revegetation. Sites with high numbers of the invasive phreatophytes will have supplemental revegetation efforts implemented. This will be done with grass seeding and tree plantings provided by the partners in the project. These partners include West Greeley Conservation District and landowners. Long-term monitoring will continue twice a year for five years after the completion of the grant- funded project. During this time, inspections will be made to determine that there is no re-growth of the treated invasive phreatophyte trees, that secondary noxious weeds have not invaded, and that any restoration activities are filling in and establishing. If there is a failure of any one of these items, follow-up will be scheduled and implemented in a timely manner. The inspections will be done by the Weld County Weed Division Supervisor and staff. Reports will be filed with the Colorado Water Conservation Board and the partners of the project. Additional meetings may be scheduled with the partners as needed. Organizational Capability 3.1 - The lead project sponsor is the Weld County Weed Division. Tina Booton, the Weed Division Supervisor, will oversee the project in general and coordinate all of the various aspects of the project. The Weld County Youth Conservation Corps (WCYCC) will do a large portion of the cut stump and chipping work to treat the Russian olive and tamarisk trees in the project area. The WCYCC will work for a total of twenty-six and a half weeks; twenty-five and a half paid for and one volunteered. A commercial tree removal contractor will work on the larger sites treating the phreatophytes and chipping the material for up to seven days; all of this work will be paid for with grant funds. The West Greeley Conservation District will provide some tree seedlings and grass seed for the revegetation project. They will also help with the educational program materials. Weld County NRCS will provide technical advice as needed. 3.2 - In 2010, a Colorado Water Conservation Board grant was secured to remove Russian olive and tamarisk along the Cache La Poudre River. Partners in this grant included the City of Windsor, City of Greeley, West Greeley Conservation District, Weld County Youth Conservation Corp and Weld County. This project was successfully completed on time and within budget. It is finishing its fifth year of maintenance. In 2014, a Colorado Water Conservation Board grant was secured to remove tamarisk and Russian olive trees along the St. Vrain River. Partners in this grant included the City of Longmont, City of Firestone, Colorado Parks Wildlife, Weld County Youth Conservation Corp, Boulder County NRCS, Longmont Conservation District and Friends of the St. Vrain. This project was successfully completed and has begun its first year of monitoring and maintenance. Since 2000, noxious weed compliance has been carried out in the South Platte River's Watershed and all of Weld County. All landowners are in compliance with terrestrial noxious weeds. This program is conducted through Weld County Weed Division. 3.3 -This plan is being developed using the Platte Invasives Endeavor Plan (PIE Plan) that was approved by the Colorado Department of Agriculture in 2010. This plan includes an overall analysis and plan for the entire South Platte Watershed. The plan is then broken down into the tributaries and their watersheds. Outlined in the plan are phreatophyte control options, riparian condition assessments, endangered species studies, and riparian restoration plans. This plan has been utilized in Weld County with the phreatophyte removal along both the Cache la Poudre and St. Vrain rivers. 3.4 - The Weld County Weed Division Supervisor, Tina Booton, will handle the major coordination and oversight during the project. She has a master's degree in agriculture with an emphasis in adult education and has worked with landowners in Weld County since 2000. Tina has been the supervisor of the department since 2005. A full time seasonal staff member was hired through a grant in 2015 to map the South Platte River for tamarisk and Russian olive trees as well as other noxious weeds. Cami Hillman came from a ranching background and dairy semen sales experience. Her knowledge and communication skills worked very well with the landowners. One full-time, fifteen month seasonal employee will also be dedicated to the project during the winter seasons of the grant to coordinate the activities. This staff member will be from the Weld County Weed Division and hired in May. The same employee will most likely be re- hired for the second portion of this project. A good portion of the work including cut stump treatments and chipping will be done by the Weld County Youth Conservation Corps. This group operates an AmeriCorps program that works with youth ages 18— 24. The youth are extensively trained in the use of hand tools and chainsaws. The crew leaders are working toward their spray license with the Colorado Department of Agriculture. The second source utilized for doing work will be a private contractor. 3.5 - The following activities are sponsored and conducted by the partner of the project. All activities are supplied as in-kind matches or cash contributions. All funding is pledged. The cash partner include: Weld County at $10,000; Colorado Department of Agriculture at $14,346; West Greeley Conservation District at $1,500; Central Colorado Water Conservancy District at $6,000; Northern Colorado Water Conservancy District at $1,000; Colorado Corn Administrative Committee at $3,250; City of Evans at $5,000; Town of Milliken at $5,000; Consolidated Mutual Ditches at $1,000; City of Greeley at $2,500; City of Fort Lupton at $1,000 and the City of Aurora at $1,500. This gives a cash match total of: $ 52,096 for this project. The in-kind match breaks down as follows. Weld County will provide supervision of the project, chemical, travel, speaking, maintenance and monitoring for the project as well as a fifteen month seasonal staff member at $28,000. West Greeley Conservation District will provide promotion through their newsletter, grass seed and seedling trees to the project for$3,500. The Weld County Youth Conservation Corps will donate 4 weeks of tree removal during the project and provide assistance during the 5 years of maintenance at a value of$45,000. The Central Colorado Water Conservancy District will provide the use of a skid steer with knife and operator at $99/ hour for 40 hours along with project promotion in their newsletter for a value of$ 9,040. The Colorado Corn Administrative Committee will promote the project in their newsletter at least once during the project at a value of $3,000. The City of Greeley will treat Russian olive and tamarisk on other city owned properties during the project at a value of$2,500. The Town of Milliken will provide the maintenance on the city owned parcel that will be addressed during the project at a value of$5000. The total in-kind match for the project is: $ 66,040. The total match secured is $ 133,540 for the project. 3.6 -The project includes an educational component to increase awareness of the invasive phreatophyte issues. These activities include speaking at local homeowners associations, meet- up groups, Young Farmers Groups, shooting associations, and other civic organizations within the project area. Press releases will be developed and submitted to local media outlets in the project area. Handouts including the posters will be created and distributed to local businesses within the project area. The program details, progress and other information will be included in the West Greeley Conservation District, Colorado Corn Administrative Committee and the Central Colorado Water Conservancy District newsletters throughout the two years of the project and for the five years of maintenance. Effectiveness of Protect 4.1 - The best treatment option for removing the invasive phreatophyte trees, while disturbing the least amount of ground, is the cut stump treatment and chipping the removed woody material. This provides the least amount of disturbance, keeping other secondary weeds from moving in by protecting what grasses and other native forbs are in the area. Using the appropriate chemical and timing with the cut stump treatment also provides the best root control. This limits the amount of re-growth that has to be addressed at a later date. To date there are no bio-control options for Russian olive trees. The bio-control option for tamarisk has limited success this far north. In addition, the area is also not heavily enough infested to support the release of these insects. Removing the trees with equipment like a back hoe creates a greater disturbed area that opens the ground for secondary weeds to infest along with increased erosion. There are limited sites where the Russian olive or tamarisk trees are growing in solid infestations. Where these areas do occur, a complete revegetation plan will be implemented to address the chance for re-infestation. The revegetation efforts will establish more readily due to the fact that there is less disturbance during the cut stump treatments. Native grasses and tree seedlings will be the plant material of choice. Monthly monitoring will be done in these highly- sensitive sites to verify that other weeds and invasive phreatophyte trees do not move into the recently cleared area. However, the majority of the Russian olive and tamarisk tree infestations are intermixed with native grasses and other trees, including willows and cottonwoods. By carefully removing the Russian olive and tamarisk trees one at a time, Weld County can better guarantee that much of the existing native vegetation is left undisturbed. This creates an advantage for the area to re- vegetate naturally. Utilizing the existing vegetation is a more reliable alternative than having to start from seed and young seedlings. 4.2 - The project budget and schedule are realistic. Working near to the water's edge will require an NPDES general permit, which Weld County already has for other spraying work that is done within the County. Otherwise, no additional permits will be required. The landowners along the South Platte, Little Thompson and Big Thompson rivers have already been identified. In 2015, contact with the landowners along the South Platte river was conducted through a letter and followed up with a phone call. These contacts allowed us to go on properties and map the noxious weed infestation as well as start to spread the word about the project. The landowner questions have been answered in 2015, making the process much easier in 2016 to start work on the project. The project timeline allows ample time to create the educational pieces, speak at the various organizations within the project area, and promote the project. There is also a twenty month window for removing the Russian olive and tamarisk trees. This large window will allow flexibility in the schedule and the ability to account for weather issues, such as rain or flooding from upstream runoff. The project partners will also have time to identify any degraded sites that need revegetation and be able to implement a plan by the end of the grant. 4.3 - There are several multi-objective aspects to this project. The first is riparian revegetation. By removing the invasive phreatophyte trees, the grant partners will be able to see what the underlying vegetation is and make a determination as to how much work is needed to return the area to a more native situation. By ensuring a healthy ecosystem of native riparian vegetation, the grant partners will be able to stabilize the shoreline with vegetation and better compete against other noxious weeds. The second half of this is habitat improvement. By addressing the invasive phreatophytes, the grant partners will be able to return the riparian corridor to a more natural state that encourages and supports wildlife in the area. Lastly this project will help enhance recreational opportunities in a number of ways. There will be an increase in wildlife numbers for viewing. There will potentially be an increase in water flows for enhanced fishing and kayaking opportunities, as well as creating easier access to the river's shoreline at public access points. Scope of Work GRANTEE and FISCAL AGENT: Weld County Weed Division and Weld County Accounting Department PRIMARY CONTACT: Tina Booton, tbooton(a�co.weld.co.us ADDRESS: PO Box 758; Greeley, CO 80632 PHONE: 970-304-6496 ext. 3770 PROJECT NAME: Tamarisk and Russian Olive Tree Eradication on the South Platte River and Tributaries in Weld County GRANT AMOUNT: $300,000 INTRODUCTION AND BACKGROUND: This Russian olive and tamarisk tree removal project is a continuation of the work that has been done in Weld County. The effort enhances the South Platte River Watershed. By removing the Russian olive and tamarisk trees, native vegetation or at least a higher quality of vegetation can establish, creating improved wildlife habitat, better water quality, and access to the river's banks for recreation. Work began on this stretch of the South Platte River in 2003 and 2004 with a grant from the National Fish and Wildlife Foundation. This grant aided in some Russian olive and tamarisk eradication; however, most of the work focused on removing other terrestrial noxious weeds and reseeding with native grass species. This continuation of effort will support the work that was begun and continue to improve the overall value of the watershed. OBJECTIVES: 1. Removal of the Russian olive and tamarisk trees from the properties that border the Little Thompson, Big Thompson and South Platte Rivers within Weld County. This is approximately 55 linear miles of river bottom lands that will be addressed. 2. Mapping of the Little and Big Thompson Rivers in the project area to provide a complete picture as to the vegetation and other stabilization materials on the shoreline of the river. 3. Establish native vegetation on any of the sites that need help in recovering from the infestations once removed. 4. Create educational posters to distribute to businesses in the project area, along with a targeted mailing to landowners telling them about the project. 5. Speak at five homeowner's association meetings and other civic organizations about the Russian olive and tamarisk tree project along with all noxious weeds. Educational materials available at local Farmers Markets and other educational opportunities. TASK 1: Russian Olive and Tamarisk Tree Removal Description: Using the Weld County Youth Conservation Corps and other contractors. Russian olive and tamarisk trees will be cut down, the stumps treated with a chemical, and the cut material chipped. The Weld County Weed Division will supply the chemical for the project. The chipped material will be left on-site for the landowner's use or spread in a thin layer as requested by the landowner. Method/Procedure: The trees will be cut down with either chainsaws or tracked skid steers equipped with grapples and shear attachments. All material will be chipped on-site. The chips will be left in a pile for the landowner to utilize, distributed in a thin layer to decompose on site or removed based on the landowners' needs. Efforts will be made to work with each of the towns and other entities to utilize the chips as mulch in local landscaping or as a soil treatment for newly seeded areas. The chemical used in the cut stump treatments will be labeled for aquatic sites, and will be Habitat, Garton 3A, or Rodeo. The proper timing and rates will be utilized. Deliverable: All of this work will take place from June 15, 2016 through March 31, 2018. TASK 2: Mapping the Little and Big Thompson Rivers Description: The mapping will focus on Russian olive and tamarisk trees, as well as any other List A and Watch List species that are migrating into Weld County. This will be conducted by Weld County staff and West Greeley Conservation District staff. Deliverable: All of this work will take place from April 1, 2016 through March 31, 2018. TASK 3: Establish Native Vegetation Description: The West Greeley Conservation District, and the Weld County NRCS will help in determining which sites need assistance with revegetation of native plant materials to limit erosion and offer competition against other noxious weeds. The materials to be used include tree seedlings of cottonwood, willow, service berry and other native shrubs, along with a native grass mix for the area. Deliverable: All of this work will take place from November 1, 2016 through March 31, 2018. TASK 4: Create Educational Posters Description: West Greeley Conservation District, along with Weld County staff will design the content and layout of these items. The West Greeley Conservation District will cover the cost of printing. Volunteers from the grant project partners will help distribute the posters. Deliverable: All of this work will take place from April 1, 2016 through July 1, 2016. TASK 5: Newsletter Promotion Description: Newsletters for West Greeley Conservation District, Central Colorado Water Conservancy District and Colorado Corn Administrative Committee will each run an article on the project throughout the length of the program. These newsletters will be mailed to large audiences in Weld County. Deliverable: All of this work will take place from April 1, 2016 through June 1, 2018. TASK 6: Speaking at Various Groups and Other Educational Outreach Description: The Weld County Weed Division Supervisor will seek out at least five speaking opportunities to promote the project and raise awareness of the impact of invasive species, especially the Russian olive and tamarisk trees. Educational materials will be made available at the CSU Extension office as well as at any educational opportunities and booths that are available during the grant project. Deliverable: All of this work will take place from April 1, 2016 through March 31, 2018. Reporting and Final Deliverable Reporting: The Weld County Weed Division will submit a report every six months from the start of the contract. The report will detail all work conducted during the timeframe and if any problems have occurred. After the completion of the project and the final report, yearly reports will be supplied for the following five years during the maintenance phase of the project. Maintenance: All work conducted through this grant will be maintained for five years following the completion of the grant. This maintenance work will begin in October of 2018 and run through October 2022. Final Deliverable: At the completion of the grant project, the Weld County Weed Division will submit a final report, including pictures and educational materials created during the project, to document the project and what was accomplished.
