Client proposing to develop the existing pinyon/juniper woodlands for residential use. The proposed proiect is located in Garfield County, Colorado in Section 21, Township 7 South, Range 88 West (6rh PrincipalMeridian) (Figure 1), SGM was retalned to conduct a noxious weed sunrey to fulfill requirements of Garfield County's IUDC and Vegetation Management department. A field survey documentlng and mapping noxious weeds was conducted on June L7,2024, by Maryanne Evans lEnvironmental Sclentistl. Both Garfield County's noxious weed list and the State of Colorado's noxious weed list were utilized for survey efforts {Appendix A and B}. To summarize, surveys found the following State and Garfield County listed noxious weeds: Table 1- Noxlous Weeds Present on Property 2.0 DESCRIPTION OF SURVEY AREA The project area is dominated by pinyon-juniper woodland slPinus edulis andJuniperus scopulorurn) intermixed with mountain mahogany {Cercocarpus montonus and C. ledifoliusl; these areas have minimal understory vegetation consisting primarily of lndian rice grasslAchnatherum hymenoidesl and green needle grass lNassella viridulal.

Cheatgrass is an aggressive invasive plant throughout the southwest and can rapidly establish itself in sagebrush, pinyon-juniper, ponderosa pine, and Gambeloak plant communities. Cheatgrass out completes native grasses because it germinates early in the spring using up soil moisture making it unavailable for other species to germinate and compete. Some of the keys to managing cheatgrass include: Limit earth disturbance and revegetate disturbed areas as quickly as possible with desirable native species, r Eradicate new populations of cheatgrass as soon as they are identified. o Combine control techniques including biological, chemical, and mechanical each of which has its own strengths. For additional information on how to control cheatgrass, the Colorado Department of Agriculture publishes guides on measures to control the wide variety of noxious weeds found throughout Colorado. Links to those fact sheets are included in Appendix C. As discussed above, S€M did not identify other significant weed anfestations within the Melonuk Subdivision Project Area, However, the following discusses reguirements of the Colorado Noxious Weed Act, as well as $arfield County's weed management plan that landowners should be aware of. To meet the requirements of the Colorado Noxious Weed Act and Garfield County guidance, land owners shall conduct prescribed management techniques for noxious weeds included on one of three State weed lists: Last A - designated for statewide eradication; List B - managed to prevent further spread and, for selected species, designated for eradication in large areas; and list C - of more localized concern, but for which the State will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. The current State list is available in Appendix A. lf populations of List A species are present in the project area, every population shall be eradicated prior to seed development. To stop the spread of list B species, populations of every species designated for eradication in a particular county shall be eliminated prior to seed development. Additionally, to meet reclarnation objectives, the operator should eliminate or minimize those noxious and invasive weeds designated as "undesirable species". Undesirable species include redstem filaree, all List C species (e,g., cheatgrass and field bindweed), and invasive species that commonly colonize disturbed or reclaimed land and impede or prevent establishment of desirable species. Control of invasive species is a difficult task and requires on-going control measures. Care must be taken to avoid negatively impacting desirable plant communities and inviting infestation by other pioneer invaders. Weed management is best achieved by employing aggressive control early on, and persistent controlefforts over several growing seasons, including direct treatments, prevention through best management practices, monitoring of treatment efficacy, and subsequent detection efforts. The following methods are recommended to manage noxious weeds, per Colorado State Universlty's Extension program. The Garfield Cou nty Vegetation Management Program and the Garfield County Noxious Weed Management Plan should be reviewed for additional guidance. Preventive: As discussed above for cheatgrass manage, the same technics are utilized for many of the other noxious weed species. Methods include maintaining healthy pastures, using weed-free crop seed, weed'free a ( I I I 6 L MelonukSubdivision Weed Manaoement plon manure and hay, and clean harvesting and tillage equiprnent, as wellas the elimination of weed infestations in areas bordering cropland, and in irrigation ditches and canals. Chemical: Herbicide treatments can be haghly effective and will vary based on time of year of treatment and species treatment. Two yearly ileatments would be recommended for the duration of the project, one in spring and one in fall. Cultural: Methods include: Establishing and managing an adequate population of desirable vegetation to compete with the weeds; utilizlng livestock (cattle, goats, sheep) when possible; mulching; burning; and even plastic weed baniers. Mechanical: Methods include: Hand-pulf hoe, mow and tillage, Biological: Biological weed control invotves the utilization of naturat enemies for the control of specific weed species. This method can take many years to result in weed control and is often not 100% effective. However, this method can dramatically help reduce weed densities and when combined with other methods can be very beneficlal. Methods include grazing, introduction of registered insects or diseases. Contact the palisade lnsecary for more information. {! 7 ( Melonuk Sub{lukig4 Weed Manaaement Plon 5.0 PROPOSED R€CIAMATION ACTIVITIES 5.1 Pre-Construction Weed Control Prior to soil disturbing activities, it is strongly advised that noxious weeds be chemically treated. This will greatly help reduce the need for noxious weed treatments in the long-term. 5.2 Vegetation Removal It is anticipated that most vegetation would be cleared from the constructaon area and cut and fill slopes. Cleared vegetation should be stockpiled, shredded or broken up, and mixed with topsoil or used for reclamation. Material should be placed in a manner to help protect reclamation area (on slopes). Excess cut vegetation should be removed to reduce visual impacts, as needed. 5.3 Erosion Control Standard erosion controls such as straw wattles should be utilized and maintained during the life of the reclamation efforts. Water bars, slope breakers, erosion control blankets, fencing, mulch, straw bales, and rolls may also be used to manage soil erosion. Soil erosion control will be accomplished on steep areas (greater than 3:1), lf possible, reclamation work and any associated soil stockpiling should be done in small enough areas to be completed prior to the next rain event. lf soil stockpiles need to be left for an extended period or during rain events, erosion and/or sediment controls will be installed. 5.4 Soil Storage The salvaged topsoil should be stored separately from subsoil or other excavated material. Windrowing of topsoil and subsoil separately should be implemented whenever topoBraphy allows. Topsoil must not be mixed or covered with subsoil material. Dry drainages or washes that ooss the construction area should not be blocked with topsoil or subsoil piles. Specifically, topsoil and subsoil should be placed outside of the Ordinary High Water Mark (OHWM) of drainages. Gaps shou ld be left at regular intervals in the windrowed topsoil to avoid ponding and diversion of natural runoff during storm events. 5,5 Long+ermlPermanent Seed Mixes Seeding should occur in the late fall to avoid seeds from germinating in the summer or fall, and then either desiccating or freezing. Drill seeding could be utilized on pastures and more level terrain, but broadcast seeding would likely be needed on steeper slopes. Drill seeding would be the preferred method where equipment access is feasible; seed should be placed in direct contact with the soilat an average depth of 0.5 inch. For drill seeding applications, small seeds shall be packaged separately to allow for separate application. Small seeds should be planted no deeper than 0.25 inch or should be broadcast. Eroadcast seeding should be employed in areas where drill seeding is not possible, Seed would be uniformly applied over the disturbed areas with manually operated cyclone-bucket spreaders or mechanical spreaders. The following Native Shrubland seed mix is a relatively "simple" mix, additional species may be added.

A, B, nnd C Listings The State of Colorado has designated 73 plants as Noxious Weeds, and has categorized them into three lists based on priority for management in Colorado. These lists have been named Lists A, B, and C. Most simply put: r List A plants are newly arrived and/or less common in Colorado and must be eradicated from all lands in the State.I List B includes plants whose continued spread in Colorado should be halted.r List C plants are those for which local governments have authority to decide the management strategy. The purpose of such categorization is to guide the State and local govemments in developing Management Strategies for each weed. The Management Strategy of a particular weed in an area may be one of the following (see Appendix E for more complete definitions): r Eradication (complctc elimination of all populations of a weed)r containment (confinomont of populations of a weed to a defined arca). SupPression (attempt to limit the vigor and spread of populations within a region) All List A species have been designated by the Colorado Commissioner of Agriculture ('the Commissioner") for eradication. This m€ans that it is a violation to allow any List A species to produce ssed or develop other reproductive means such as roots, shoots and runners. Many List A weeds are not yet present in Colorado, but have become a problem in neighboring states. Others are present in small isolated populations. It is the intent of the Commission to eliminate these species before they become widespread. The Rules allow the local governing authority to file for a compliance waiver if it is dCtermined that eradication is not a practical management objective for specific populations. List B weed species may be designated for eradication, suppression, or containment, depending on the extcnt of their pres€nce in a particular county. The local Management Strategy for each List B species in each county is determined by the Commissioncr (in consultation with the State Noxious Weed Advisory Committee, local gov€nrments, and other interested parties). From these local Management Strategies, thebommissioner develops a State-wide noxious weed management plan for eaci List B species. This Plan is designed to.stop the continued spread of List B species, making it a violation to allow any List B species to spread into sny un-infested area. Local governments are lcft to decide whether to require managcment of List C weed species, and, if so, whether the Management strategy will be Eradication, Containment, or suppression. state Management Plans for List c weed species developed by the Commissioner are designed to support the weed management efforts of local governing bodies. The goal of such plans is not to stop the continued spread of these specirs. Ralher, lhey $e meant to provide additional education, rescarch, and biological conbol resources to jurisdictions that choose to require management of List C species. r' ( B.
