Subject: Integrated Noxious Weed Management Plan, Golden Currant Waterline Project, Fort Collins, Larimer County, Colorado Introduction The Fort Collins Loveland Water District is planning to install a new 30-inch-diameter waterline directly east of Horsetooth Reservoir in Fort Collins, Colorado (“project”; Figure 1). CivilWorx, LLC is providing the design services and Pinyon Environmental, Inc. (Pinyon) is providing environmental support services for the project, which includes the completion of this Integrated Noxious Weed Management Plan (INWMP). The project is located on the Maxwell Natural Area and on private land managed by the Ponds at Overland Trail Homeowner’s Association (HOA). Restoration (including weed management efforts) of natural areas requires on-going coordination with the City’s Natural Area Department (NAD). Restoration of the remaining private land will also follow this INWMP, but specific techniques may be amended after coordination with the private land manager and the City’s Land Conservation Manager. This INWMP and the accompanying Conceptual Restoration Plan may be amended based on input from land management personnel (Pinyon, 2021a). When implemented properly, this INWMP fulfills county and state noxious weed management requirements and recommendations, including: • Colorado Executive Order D 006 99 Development and Implementation of Noxious Weed Management Programs (Colorado Executive Branch, 1999) • Colorado Noxious Weed Act (Colorado Revised Statutes; Title 35, Article 5.5) (Colorado Revised Statutes, 2016a) • Larimer County Code of Ordinance Weeds and Wild Growth (Chapter 30, Article 3) (Larimer County, 2020) • Larimer County Noxious Weed Management Plan (Larimer County, 2018) • City of Fort Collins Code of Ordinance Weeds, Brush Piles and Rubbish (Chapter 20, Article 4) (City of Fort Collins, 2020) Project Description and Location This project will install a new 30-inch-diameter waterline approximately six feet underground. The typical trench section will be about six feet wide with a trench box. Soil stockpiles, vehicle traffic, and surface Integrated Noxious Weed Management Plan Golden Currant Waterline Project Page 2 disturbance will be limited to 30 feet on either side of the waterline (project area). Conventional excavation equipment, including diesel-powered hydraulic excavators and front-end loaders will be used to construct the new waterline. The project location is shown in Figure 1 and described in Table 1. Table 1.

Because of the adverse effects of noxious weeds to the environment and the economy, the Colorado Noxious Weed Act requires landowners and managers to eradicate and/or control the spread of noxious weeds. The Colorado Department of Agriculture (CDA) is the lead agency in charge of noxious weed management requirements and recommendations in Colorado. The CDA classifies noxious weeds into three categories: List A (high priority), List B (medium priority), and List C (low priority) (CDA, 2020). List A species have been designated by the CDA for eradication, meaning that known locations of List A species require treatment. List B species have been designated for eradication, suppression, or control based on species and location. The CDA has written management plans for all List A and most List B noxious weed species. These management plans are included in the Code of Colorado Regulation 8 CCR 1206-2 Rules Pertaining to the Administration and Enforcement of the Colorado Noxious Weed Act (CDA, 2018). The CDA does not yet have written management plans for List C species and therefore does not yet require management for List C species. The management plans for List C species will be designed to support the efforts of local governing bodies to facilitate more effective integrated weed management on private and public lands. The goal of these plans will not be to stop the continued spread of these species but to provide additional education, research, and biological control resources to jurisdictions that choose to require management of List C species (CDA, 2018). The CDA also maintains a Watch List of weed species that may become problematic and may need to be listed as noxious weeds in the future. Additionally, the Colorado Noxious Weed Act stipulates that each county in Colorado must adopt a noxious weed management plan for its jurisdiction. The Larimer County Noxious Weed Management Plan was approved by the Board of County Commissioners on November 20, 2028 and defers to the state noxious weed list and management goals (Larimer County, 2018). Integrated Noxious Weed Management Plan Golden Currant Waterline Project Page 3 Noxious Weed Species Identified in the Project Area On April 4, 2019 Pinyon conducted a biological resource assessment of the project area (Pinyon, 2019). During the assessment, several noxious weed species were identified; this INWMP addresses those species. A targeted noxious weed mapping effort has not been conducted for this project. A summary of the noxious weeds identified in the project area during the 2019 biological resource assessment, along with the associated management goals, are presented below in Table 2. Table 2.

Integrated Noxious Weed Management Plan Noxious Weed Management Priorities Noxious weed management should prioritize treatment of the two List B species identified in the project area: musk thistle (Carduus nutans) and Russian olive (Elaeagnus angustifolia). Musk thistle and Russian olive trees were identified during the 2019 biological resource assessment as scattered, isolated infestations. Targeted management of these species is therefore critical, as it is easier to suppress and/or eliminate infestations when severities are low versus after the infestations have spread. Treatment recommendations for musk thistle and Russian olive are described in the sections below and detailed in the CDA Noxious Weed Fact Sheets (Attachment 1). Integrated Noxious Weed Management Plan Golden Currant Waterline Project Page 4 Conversely, List C (low priority) noxious weed species are prevalent throughout the area and may require broad applications of herbicide to treat. Broad herbicide use throughout the project area may inhibit the growth of new seeds during revegetation; therefore, treatment of List C species is not currently recommended. Noxious Weed Best Management Practices Pre-Construction and During Construction The following best management practices (BMPs) shall be performed prior to construction and/or during construction, as appropriate: • Construction personnel shall be made aware of this INWMP and the correct implementation of the BMPs contained herein. • List B species identified in the project area (musk thistle and Russian olive) shall be treated as follows: o Musk thistle: Musk thistle is a biennial plant that reproduces only from seed. Therefore, the prevention of seed production is key to management of the species. Musk thistle should be treated prior to seed production while the plants are in the rosette stage in early spring. Mechanically severing musk thistle roots and/or applying targeted herbicide applications can be effective treatment options. If herbicides are used, the chemicals should be applied directly to the individual rosettes (i.e., not broadcasted). o Russian olive: Russian olive is a perennial tree that reproduces by seed or root suckers. On December 17, 2020, the project completed a tree inventory to meet mitigation requirements outlined by the City of Fort Collins Forestry Division; results of that inventory were documented by Pinyon in a memorandum on January 8, 2021 (Pinyon, 2021b). As documented in the memorandum, one Russian olive tree was noted within the estimated limits of disturbance and is currently slated for removal. Treatment recommendations for removal include removing the tree to the stump and immediately treating the freshly cut stump with herbicide (Attachment 1). Because of the environmental risks associated with herbicide use, all herbicide applications must be performed by personnel under the supervision of a certified applicator licensed by the CDA (in accordance with the Colorado Pesticide Applicator Act, Colorado Revised Statues; Title 35, Article 10) and in accordance with the product label (Colorado Revised Statutes, 2016b). • Contractor vehicles shall be inspected before they are used for construction to ensure that they are free of soil and debris capable of transporting noxious weed seeds or roots. Heavy construction equipment shall be cleaned prior to use in the project area. Post-Construction Revegetation and Monitoring The project Conceptual Restoration Plan includes a list of native seeds to be planted and guidelines for post- construction monitoring to ensure that the project meets success criteria (Pinyon, 2021a). In addition to the BMPs listed in the revegetation plan, the following BMPs should be followed: • If areas are completed and permanent stabilization (i.e., seeding) cannot occur due to the time of year (e.g., winter months), mulch and mulch tackifier will be used for temporary erosion control until seeding can occur. Integrated Noxious Weed Management Plan Golden Currant Waterline Project Page 5 • All topsoil, either imported or salvaged on the study area, shall be treated with an herbicide for noxious weeds prior to final seeding (ensure timing of herbicide application does not impact seed germination). • Only certified weed-free mulch and hay/straw bales shall be used on the project (in accordance with the Colorado Weed Free Forage Crop Certification Act, Colorado Revised Statues; Title 35, Article 27.5) (Colorado Revised Statutes, 2016c). Documentation To show that noxious weed management activities are being implemented, activities related to noxious weeds should be documented. A sample form that can be used to document weed management activities has been included in Attachment 2. This form can be used to document various noxious weed management-related activities including: • Noxious weed inventory and/or inspections. • Noxious weed management activities. • Vehicle and/or equipment inspections. In addition to the filled-out form documenting noxious weed management activities, other documentation shall also be maintained. This documentation may include: • Copies of seed tags that document noxious weed percentage. • Seed testing results. • Weed-free certification for hay bales and straw. • Weed-free certification for topsoil. • Herbicide spray sheets that include the name, company, and CDA license number of the herbicide applicator, as well as the herbicide type, amount, and target species of application.

Musk thistleColorado Dept. of Agriculture, Conservation Services Division 700 Kipling Street Suite 4000 Lakewood, CO 80215 303-239-4100 Broad, spine- tipped bracts located under the flower Flowering heads are terminal, solitary, and usually nodding Grows up to 6 feet tall 1. 2. 3. Identification and Impacts M usk thistle (Carduus nutans) is a non-native biennial forb that reproduces solely by seed. A biennial is a plant that completes its lifecycle within two years. During the first year of growth, musk thistle appears as a rosette in spring or fall. During the second year in mid to late spring, the stem bolts, flowers, sets seed, and the plant dies. Musk thistle produces many flower heads. The terminal, or tallest, shoots flower first, then lateral shoots develop in leaf axils. A robust plant may produce 100 or more flowering heads. A prolific seed producer, musk thistle can produce up to 20,000 seeds per plant, only one-third being viable. Because musk thistle reproduces solely from seed, the key for successful management is to prevent seed production. M usk thistle can grow up to 6 feet tall. The leaves are spiny, waxy, and dark green in color with a light green midrib. The flowers are purple, large in size (1.5 to 3 inches in diameter), nodding, and terminal. The flowers are surrounded by numerous, lance-shaped, spine-tipped bracts. You can expect to see flowers from late May and June. Seed set usually occurs in June or July and effective management options will then become limited. Key ID Points Carduus nutansMusk thistle Identification and Management H abitats for Musk thistle include disturbed, overgrazed areas. Once a pasture is infested, the livestock carrying capacity for that area is significantly decreased. The plant may also occur on rangeland, roadsides, ditches, riparian areas, and trails. T he key to effective control of Musk thistle is to prevent the plant’s seed production, Planting desirable grasses and forbs to out compete Musk thistle can also be effective. Dense Musk thistle stands can be treated by spot treatments of herbicides and by a persistent mechanical program. Details on the back of this sheet can help to create a management plan compatible with your site ecology. M usk thistle is designated as a “List B” species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Or call the State Weed Coordinator at the Colorado Department of Agriculture, Conservation Services Division, 303-239-4100. List B Species Rangeland, pasture, and riparian site recommendations Updated on: 08/08 CULTURAL Establishment of selected grasses can be an effective cultural control of Musk thistle. Contact your local Natural Resources Conservation Service for seed mix recommendations. Maintain healthy pastures and prevent bare spots caused by overgrazing. Bareground is prime habitat for weed invasions. BIOLOGICAL Livestock tend to avoid grazing on musk thistle, although horses and cattle have been known to eat the flowerheads. Biological control insects, such as the seed head weevil and the crown weevil are effective on large infestations. When used together, these insects provide fair to good control. Contact the Insectary, Colorado Department of Agriculture to get complete information at 970-464-7916. Or visit www.colorado. gov/ag/csd. MECHANICAL Any mechanical or physical method that severs the root below the soil surface will kill Musk thistle. Mowing or chopping is most effective when Musk thistle plants are at full-bloom. Be sure to properly dispose of the flowering cut plants since seeds can mature and become viable after the plant has been cut down. Top to bottom photos, © Norman E. Rees, USDA Agricultural Research Service; Whitney Cranshaw, Colorado State University, Bugwood.org; and Kelly Uhing, Colorado Department of Agriculture.Musk thistleIntegrated Weed Management: The key to managing Musk thistle is to prevent seed production. Dense Musk thistle stands can be treated by spot use of herbicides and by a persistent mechanical program. Due to the long seed viability of musk thistle, up to 10 years, control methods may have to be repeated for many years to completely eliminate an infestation.http://www.colorado.gov/ag/csdHERBICIDES NOTE: The following are recommendations for herbicides that can be applied to range and pasturelands.

Flowers have 4 small sepals and are light yellow clusters. Red-yellow fruits on mature plants. 1. 2. 3. Identification and Impacts R ussian olive (Elaeagnus angustifoilia) is a perennial tree or shrub that is native in Europe and Asia. The plant has olive- shaped fruits, silver color at first then becoming yellow-red when mature. Russian olive can reproduce by seed or root suckers. Seeds can remain viable for up to 3 years and are capable of germinating in a broad range of soil types. Spring moisture and slightly alkaline soil tend to favor seedling growth. The plants extensive root system, sprouts root suckers frequently. The stems can reach up to 30 feet in height with branches and trunks that have 1 to 2 inch thorns. Leaves are 2 to 3 inches long, alternate, narrow, have simple blades, and are untoothed. The lower surface is silvery white with dense scales, while the upper surface of the leaf is light green in color. Flowers are 4 small sepals in light yellow clusters, fragrant, and appear May through June. Russian olive twigs are flexible, reddish, and have surfaces coated with gray and scaly pubescence, becoming smooth. O nce thought to be a beneficial windbreak tree, it since has been deemed detrimental to the environment. Russian olive can grow in a variety of soil and moisture conditions, but prefers open, moist riparian zones. It is shade tolerant and can be found along streams, Key ID Points Elaeagnus angustifoiliaRussian olive Identification and Management fields and open areas. Russian-olive can out compete native vegetation, interfere with natural plant succession and nutrient cycling, and tax water reserves. Because Russian-olive is capable of fixing nitrogen in its roots, it can grow on bare, mineral substrates and dominate riparian vegetation. Although Russian-olive provides a plentiful source of edible fruits for birds, ecologists have found that bird species richness is actually higher in riparian areas dominated by native vegetation. T he key to effective control of Russian olive is preventing establishment of the trees or shrubs. If plants are already present, control options include cut-stump treatments and mechanical mowing. These treatments are dependant on size and location of the plant. Details on the back of this sheet can help to create a management plan compatible with your site ecology. R ussian olive is designated as a “List B” species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Or call the State Weed Coordinator at the Colorado Department of Agriculture, Conservation Services Division, 303-239-4100. List B Species Rangeland, pasture, and riparian site recommendations List B Species  CULTURAL Cultural controls are not an option when dealing with Russian olive. Replacing with native trees is important once Russian olive has been removed. Contact your local Natural Resources Conservation Service for recommendations of other possible trees or shrubs. BIOLOGICALTubercularia canker overwinters on infected stems and spreads via rain-splash, animals, or pruning implements to open wounds in the bark. Infected tissue becomes discolored or sunken. Entire stems may be girdled and killed, and the disease can deform or kill stressed plants over time. For more information, contact the Colorado Department of Agriculture’s Insectary in Palisade, Colorado at 970-464-7916. MECHANICAL Mowing hedges with a brush type mower, followed by removal of cut material may be the most effective method for eradication. Stump sprouting commonly occurs after cutting down the tree, and excavation of the entire stump can trigger root sprouting. Burning is practical when conditions support a long hot fire and most effective in summer or early fall. Saplings are most sensitive.

Integrated Weed Management: The most effective combination of control efforts has been cutting trees, followed by either spraying or burning the strumps. “Cut-stump” treatments that are applied during the winter months, using an approved herbicide seems effective. Trees are “cut” with a hatchet or chainsaw, then immediately treated with herbicide on the open wound.Russian olivehttp://www.colorado.gov/ag/csd HERBICIDES NOTE: The following are recommendations for herbicides that can be applied to range and pasture - lands.
