The data derived from monitoring is intended to inform weed management, irrigation, site protection, and on-going adaptive management (e.g., reseeding, grade/erosion control, site protection, etc.) necessary to accomplish the project’s restoration goals. Adaptive Management Adaptive management is an iterative process, incorporating monitoring results to inform ongoing maintenance and re-treatments that may be required to achieve long-term success of a restoration project. Monitoring provides an essential step in the adaptive management process, providing feedback for land managers and project designers, as well as allowing for the comparison of long-term results with baseline conditions. The identification of maintenance treatments (e.g., weed management, irrigation, site protection, spot seeding, etc.) are the primary product of adaptive management plans. Like initial revegetation results, maintenance treatments will be assessed over the long term via monitoring, the results of which will inform future maintenance efforts via an adaptive management process. In this regard, adaptive management is a cyclical process, especially in an urban or suburban setting where ongoing threats to natural areas exist in perpetuity. Monitoring Overview Monitoring is the process of measuring or assessing specific physical, chemical, and/or biological parameters of a project over time (Thayer, 2003) (Natural Resources Conservation Service, 2007). Using subjective (i.e., qualitative) or objective (i.e., quantitative) methods, monitoring can be used to help identify and address project failures due to potential stressors (drought, insect damage, flooding, etc.) and inform maintenance activities. Qualitative methods, such as visual observations (i.e., repeat photographic points or completion of subjective monitoring forms), can effectively document site changes and quickly inform maintenance activities necessary to correct problems. However, purely qualitative approaches such as repeat photography or other casual observations can often over- or under-represent important data such as vegetation cover. Such errors can occur because of observer bias (e.g., a human’s natural tendency to score green vegetation higher than bare soil) as well as limitations Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 4 | P a g e of methodology (e.g., the oblique angle represented in repeat photographs taken across a landscape reveal significantly higher vegetation cover than that same cover measured from an aerial point of view). Conversely, quantitative monitoring is more data-driven and aims to measure project outcomes through science-based methods aimed at reducing observer bias. Quantitative monitoring results may also be used to guide the criteria and methodology for future restoration projects and maintenance activities of a site, more accurately address permitting and funding entity requirements, support requests for contractors to perform on various warranty items (e.g., a minimum of 50% vegetation cover), and allow for sound long-term tracking of the changes in certain parameters of a site (e.g., changes in plant community structure and composition over time). At Guardian Storage, monitoring can answer important questions for post-restoration management, and provide meaningful direction for adaptative management. Some of these questions, from Living Streambanks: A Guide to Bioengineering Treatments for Colorado Streams (Giordanengo, 2016) include: • Were the appropriate treatments designed and implemented correctly to achieve restoration goals? • Were project outcomes achieved according to project goals? • Are management activities (i.e., mining, hiking, rural/residential landscaping, grazing, other land use) negatively affecting project outcomes? • Have site conditions changed in a way that requires an adjustment to existing structures, replacement of structures or vegetation, or installation of new treatments? • Is the vegetation community on the expected trajectory of recovery, or are important design components missing? • Have invasive or noxious species negatively impacted the site? The nature, frequency, and intensity of monitoring will vary depending on the questions being answered by the monitoring program, available resources (e.g., volunteers, staff, equipment, finances), and the nature of the elements (e.g., vegetation cover) being monitored. With an assumption that monitoring resources are limited, yet to ensure reliable data gathering, we have drafted a monitoring strategy and resources to carry out monitoring activities on this project site. Monitoring Goals An essential first step to monitoring is the development of specific restoration objectives (e.g., more specific than the original project goals) for Guardian Storage, against which monitoring Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 5 | P a g e results can be measured. The following goals are provided as a recommendation. These goals should be verified by the client and additional goals may be required by various permit agencies such as the US Army Corps of Engineers, US Fish and Wildlife Service (i.e., management for T&E species), and others. Revegetation Goals: Goal 1: Mitigate for wetland loss due to construction activities to City of Fort Collins standards. Goal 2: Create Natural Habitat Buffer Zone per City of Fort Collins Land Use Code 3.4.1. Given these goals, specific elements to measure over time include: • Vegetation cover, woody species density, and vegetation structure in (at a minimum) wetland mitigation areas. As time permits, vegetation cover and woody plant density and structure should be measured in all restored habitats, • Weed densities and distribution. • Successful native upland establishment, with native groundcover having 70% cover and less than 10% weed cover. Types of Monitoring Monitoring, by definition, should be conducted over time, and should utilize consistent approaches to accurately compare data over the length of the monitoring effort. Lewis et al. (2009) recommend four fundamental monitoring types to answer principal questions: • Pre-project assessment (i.e., documentation of the current site conditions and how they inform project selection and design). • What are the existing site conditions and the reasons for project implementation? This is like baseline monitoring, though does not attempt to document pre-disturbance conditions. • Implementation monitoring is done to establish the accuracy of construction. • Was the project installed according to design specifications, permits and landowner agreements? • Effectiveness monitoring is used to assess post-project site conditions and to document changes resulting from the implemented project. • Did attributes and components at the project site change in magnitude expected over the appropriate time frame? This is accomplished through comparison with pre-project and post construction conditions. • Validation monitoring is used to determine the cause-and-effect relationship between the project and biotic or physical response. Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 6 | P a g e • Did macroinvertebrates, wildlife, or water quality respond to the changes in physical and biological attributes or components brought about by the project? Pre-project monitoring at Guardian Storage was conducted by AloTerra in the form of an Ecological Characterization Study. Implementation monitoring (i.e., quantifying the location and type of restoration work completed, as compared to the intended design) will be completed during construction. Effectiveness and validation monitoring are proposed in this plan and are recommended for a minimum of three growing seasons post-construction. Both qualitative and quantitative methods will be employed to ensure management objectives are being met. If it is determined that objectives are not being met, management will adapt to ensure the desired results. Given budgetary constraints, even the most basic monitoring methods can inform adaptive management decisions important to the long-term maintenance of a project. However, as the results of qualitative monitoring can vary significantly from one observer to another, every effort should be made to integrate at least categorical observations (i.e., high, moderate, low, none; or scoring 0-5 for various element conditions). An important key, regardless of the complexity or cost of the monitoring method(s) used, is to employ repeatable/consistent methods over time. As personal and management circumstances change over time, data will be collected and managed in a way that can be easily understood and interpreted by a variety of future land managers and practitioners. We recommend a combination of monitoring methods to properly assess whether management objectives are being met at Guardian Storage. The methods proposed include: • Line-intercept procedure (Herrick, 2005) to measure plant community composition, especially herbaceous vegetation. This method is highly accurate and repeatable over time, • Noxious weed assessment (categorical observation-based protocol), • Plant survivorship counts (objective assessment), • General site condition assessment (categorical observation-based protocol), and • General assessment for wetland condition, using cover plants by wetland indicator status. Monitoring Timeline and Responsibilities Vegetation monitoring will be conducted once per year for three years following construction. We will conduct vegetation monitoring at the peak of the growing season, approximately late July to early August. Weed assessments should occur in mid spring, to inform the need and extent of subsequent treatments required to address weeds of concern. Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 7 | P a g e Responsibilities AloTerra is responsible for the vegetation, noxious weed, wetland condition assessment, upland condition assessment, and overall site condition assessments and reporting. Monitoring Methods This section provides a summary of monitoring methods for native and non-native vegetation at the Guardian Storage mitigation site. Appendix B includes a static version of the monitoring forms for these monitoring methods. Vegetation Monitoring Vegetation Cover: The line-point-intercept method will be used to quantify herbaceous vegetation cover in revegetated areas. 10 transects are recommended (6 in uplands and four in riparian areas – adjacent to the bankfull elevation). See figure 1 for proposed transect locations. Survivorship: A simple quantitative measure to document shrub and tree survivorship is a shrub survivorship inventory (Appendix B). Weed Populations: Refer to the monitoring form in Appendix B. General Wetland Condition Assessment A product of the vegetation cover data, to determine if the wetland mitigation area is developing hydrophytic vegetation typical of expected facultative wetlands in the region. Figure 1. Vegetation Monitoring Map with photo point and transect locations Weed Management With regards to their impacts on native plant communities and/or social values, non-native plants (i.e., weeds) can be benign, invasive, or noxious. Weeds have long been recognized as ecologically and economically detrimental for multiple reasons, a complete account of which is beyond the scope of this document. Several non-native aggressive species have been identified in Guardian Storage, which are capable of out-competing native plants for water, light, and nutrients, or secrete phytotoxins which actively inhibit the growth of native vegetation while providing minimal benefits about soil stabilization, forage, and other wildlife and pollinator benefits in comparison to native vegetation. These invasive species have an advantage over native species in part because they lack the full spectrum of biological controls (i.e., insect predators, plant pathogens, etc.) that serve to keep their populations in check in their country of origin. As such, they are more likely to continue to spread unabated throughout a watershed by displacing native plants and forming dense monocultures in disturbed conditions such as those present immediately following a construction project. Several non-native species at Guardian Storage were identified during initial vegetation assessments by AloTerra. Though a formal weed inventory was not conducted, the initial assessment provided a comprehensive list of weeds and their state rank (Table 1). A formal weed inventory should be conducted in the summer of 2022 to map the density and distribution of weeds more accurately in Guardian Storage. The Colorado Noxious Weed Act (C.R.S. 35-5.5-101-119) creates a legally binding obligation for the removal/control of noxious species. Through the Colorado Department of Agriculture, a list of A, B, and C species is managed and periodically updated to prioritize the control of weeds. To assist with weed management, a great variety of weed management resource s are provided by these entities, including how to create a weed management plan, best management practices for weed management, and more: Colorado Department of Agriculture website: https://www.colorado.gov/pacific/agconservation/noxious-weed-publications, Colorado State University Extension, Weed Resources: http://www.ext.colostate.edu/sam/weeds.html Colorado Weed Management Association https://cwma.org/ Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 10 | P a g e State of Colorado Noxious Weed Act Priority List Definitions: List A - Species that have not become established in the state and may have not even been reported in the state yet. The most effective way to treat these species is to eradicate them wherever they are found, and to prevent their introduction into the state if th ey are not yet present. List B - Species for which the Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, develops and implements state noxious weed management plans designed to stop the continued spread of these species. List C - These are species for which the Noxious Weeds Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, will develop and implement state noxious weed management plans designed to support the efforts of local governing bodies to facilitate more effective integrated weed management on private and public lands. The goal of such 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. The goal of such plans will not be to stop the continued spread of these species but to provide additiona l education, research, and biological control resources to jurisdictions that choose to require management of list C species. Watch List (WL) - Species that have been determined to pose a potential threat to the agricultural productivity and environmental values of the lands of the state. The Watch List is intended to serve advisory and educational purposes only. Its purpose is to encourage the identification and reporting of these species to the Commissioner to facilitate the collection of information to assist the Commissioner in determining which species should be designated as noxious weeds. When managing for weeds at Guardian Storage, given the goals of increased biological and structural diversity of a site, it is important to note that the list of species in Table 1 are not the only species to be managed. Species such as tumble mustard (Sisymbrium altissimum, unlisted in Colorado) are not a significant concern, while species such as common kochia (Kochia scoparia, unlisted in Colorado) can be highly disruptive to a restoration project and to long-term site management. As such, our weed management recommendations below target listed and unlisted species alike, whether their management is required by the State of Colorado. The most cost-effective time to manage invasive vegetation is early in a project’s lifetime before invasive plants have a chance to spread through abundant seeds or vegetative propagules. Since the initial monitoring stage has taken place, and species of concern have Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 11 | P a g e been identified and documented prior to project implementation, treatment of these species will occur prior, during, and after construction as needed. Consistent monitoring will take place throughout and after project implementation, which will identify whether follow-up treatments are required to address most invasive species problems. Table 1.

This will also increase biodiversity and will provide greater protection of slopes and banks. Site management should integrate a variety of restoration and management activities to control the invasion of non-native vegetation, which include: • Selecting appropriate and diverse early- to mid-seral seed mixes with the potential to fully occupy a given area’s botanical niches, • Seeding and planting in optimal seasons, and using appropriate seeding rates and seeding methods to increase the likelihood of high vegetation cover in the early years following restoration, • Applying appropriate levels of soil amendments, as determined by proper soil testing, • Minimizing or eliminating the use of nitrogen, as invasive species are preferentially stimulated over native species using nitrogen, • Paying close attention to the invasive species seeds that are often present in a seed mix , • Eliminate the presence of undesirable non -native species brought to the restoration sit e by heavy equipment, and via other vectors (cattle and other livestock, clothing and boots of residents and volunteers, and others) • Pre-treating the project site to remove invasive and noxious species, Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 12 | P a g e • Eliminating small patches of invading weeds before they become established and spread, • Developing an iterative weed management plan, informed by regularly scheduled monitoring, and • Keeping records of all weed management activities to aid in monitoring and future planning. Weed Treatments The treatments below include a combination of mechanical and chemical treatments for species known to occur at Guardian Storage. However, after restoration activities have occurred, this list may change. A complete weed survey should be conducted to better understand the extents of each weed population, and hence develop a comprehensive weed management plan based on priority species and their current and projected distribution. In addition to the treatments below, biological controls may also be available, and should be researched as desired. Brea arvense/Cirsium arvense (Canada thistle) • List B invasive: Control is necessary to decrease spread. If left unchecked, can create monoculture. • Perennial • Control: Chemical - Aminopyralid (Milestone; wetland approved) @ 5 oz/acre; best applied at bud or flowering. Combinations of mowing followed by chemical control have been shown to be effective on the Front Range. Spreads by rhizomatous roots. Mowing without subsequent herbicide application prior to flowering and tilling can invigorate and increase its spread. Bromus tectorum (cheatgrass) • List C: If left unchecked, can create monoculture. • Winter annual: Control is early spring or fall. • Control: Chemical - Imazapic (Plateau) at 4 oz/acre – not wetland approved; aquatic labeled glyphosate (Rodeo) 8 oz/acre – wetland approved / non-selective. Most effective before seed set and in early growth stage. Mechanical - Regular mowing before seed set has also been shown to be effective on the Front Range. Cynoglossum officinale (houndstongue) • List B. Easily controlled in its floret stage. • Biennial: Control in floret stage. Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 13 | P a g e • Control: Mechanical - hand pulling/digging can be effective, remove entire root crown in rosette stage. For flowering plants, remove flowering stock just before seed set. If you suspect seeds are present, bag seed heads as appropriate. Chemical -1.5 oz/acre metsulfuron methyl (Escort Xp). Euphorbia esula (leafy spurge) • List B. • Perennial. • Control: Chemical – 0.5 to 1 lb per acre of Quinclorac (Quinstar 4L) plus 1% methylated seed oil. Most effective time of year is from mid- to late June when true flowers begin to appear and then again in mid-September when fall regrowth has begun. Dipascus laciniatus (cutleaf and common teasel) • List B. • Biennial: Control in floret stage. • Control: Mechanical - Hand pulling/removal with shovel can be effective if performed annually until population is eradicated. Sever roots at least 2” below ground to reduce resprouting from perennating buds. Two treatments likely required. Chemical - Milestone (Wetland approved) @5 oz/acre. Koschia scoparia (kochia/burning bush) • Not listed, but control is necessary to decrease spread. If left unchecked, can create monoculture. • Annual: Control in early growth stages, before producing seed. • Control: Chemical – preemergent – indaziflam (Esplanade) @ 3.5-6.5 oz/acre. Postemergent –fluroxypyr (Vista XRT) @6-22 oz/acre (may be applied as a mix with 2,4-D @ 1 pint/acre such as in the product Trumpcard). Mechanical - hand pulling/digging can be effective. For flowering plants, remove flowering stock just before seed set. If you suspect seeds are present, bag seed heads as appropriate, and pull plant with taproot attached. Lactuca serriola (prickly lettuce) • Not listed, but if left unchecked, may create monocultures. • Annual. • Control: Mechanical - Hand pulling/removal with shovel can be effective if performed annually until population is eradicated. Sever roots at least 2” below Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 14 | P a g e ground in order to reduce resprouting from perennating buds. Two treatments likely required. Chemical – Milestone @ 5 oz/acre. Rumex crispus (curly dock) • Not listed, but easily controlled. • Biennial: Control in floret stage or end of year after seed heads have been cut and bagged. • Control: Chemical - Milestone (wetland approved) @ 5 oz/acre. Mechanical - hand pulling/digging can be effective. For flowering plants, remove flowering stock just before seed set. If you suspect seeds are present, bag seed heads as appropriate. For rosettes, sever root at least 2” below soil surface to avoid resprouting from perennating buds. Salsola tragus (Russian thistle) • Not listed, but control is necessary to decrease spread. If left unchecked, can create monoculture. • Annual: Control in early growth stages, before producing seed. • Control: Chemical – Apply in early spring, while plants are rapidly growing. Preemergent – Chlorsulfuron (Telar) @ 1-2 oz/acre. Postemergent – Glyphosate (Rodeo) @1.5 qt/acre. Mechanical - hand pulling/digging can be effective at early growth stages. For flowering plants, remove flowering stock just before seed set. If you suspect seeds are present, bag seed heads as appropriate. Verbascum Thapsus (common mullein) • List C. • Biennial. • Control: Treat in floral stage just before seed set (for flowering plants) and any time of year during rosette stage. Mechanical - hand pulling/digging can be effective. For flowering plants, remove flowering stock just before seed set. If you suspect sees are present, bag seed heads as appropriate. For rosettes, sever root at least 2” below soil surface to avoid resprouting from perennating buds. Chemical - Milestone (wetland approved) @ 7 oz/acre with 0.5% non-ionic surfactant. Herbicide Note Taking into consideration the proximity to homes and water, we have carefully selected 9 herbicides to be used on the invasive species listed above. Some species, especially annuals and biennials growing in low density, may not require any chemical applications. Regardless of the control method used, we recommend up to 3 treatments a year depending on the Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 15 | P a g e labeled maximum annual application rate to ensure sufficient kill rates. The chemicals that we suggest are described below. Always read, understand, and follow the label directions. The herbicide label is the LAW! Contact an herbicide expert or your local extension office if there are any questions regarding usage. • Aminopyralid (Milestone) is a safe, effective herbicide that can be used safely (wetland approved) around water supplies (no surfactants) and is grazing approved . However, be sure to read the supplemental information related to grazing and compost. • Rodeo is wetland approved (no surfactants) glyphosate . The herbicide is not selective and will impact all plants it contacts. • Metsulfuron-methyl (Escort XP) is a selective herbicide that targets broadleaf weeds, brush, and several woody vine species. Escort XP will break down readily in soil has a low soil residual. The active ingredient in Escort XP (Metsulfuron -methyl) is very low in toxicity to wildlife even when used in high concentrations. It’s approved for use near or around bodies of water but not when applied directly to water. • Imazapic (Plateau) is listed under cheatgrass because it is a very selective herbicide and will not harm other plants surrounding the target species. It is however not wetland approved. For this reason, careful consideration will be given to the proper treatment method for this species upon further inspection of site. • Imazapyr (Habitat) is a strong broad-spectrum herbicide with aquatic formulations that will provide control of hairy willow-herb. It is only recommended for controlling hairy willow-herb. • Chlorsulfuron (Telar) is a low-use rate broadleaf selective residual herbicide that, when applied in fall, can reduce spring weed populations by up to 90%. Given it’s low-use rate (low chemical load) it won’t stress the environment like other high-use rate herbicides. This herbicide will also allow some native forbs such as milkweeds to grow while suppressing the target weed. Telar is not wetland approved. • Indaziflam (Esplanade) is a selective preemergent herbicide that is used to control many annual grasses and broadleaf weeds. Esplanade works by suppressing the germination of seeds and the emergence of seedlings in the spring and is not wetland approved. • Fluroxypyr (Vista XRT) is a broadleaf specific herbicide that provides excellent control of Kochia including glyphosate and dicamba resistant biotypes. Vista XRT is not wetland approved. • Quinclorac (Quinstar 4L) is used to suppress certain broadleaf weeds while having little to no effect on grasses. It is safe to use up to the water’s edge but should not be used in areas that are/become inundated with water. Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 16 | P a g e Site Protection In addition to being aware of the negative effect invasive plants can have on desired native vegetation, this plan considers the impact recreation and wildlife can have on newly planted vegetation. Wildlife Control Unmanaged impacts from livestock or wildlife in a revegetation site can be devastating to newly established plant materials. As such, wildlife population such as deer and elk should be observed closely for a period of four to three years post-construction. Once riparian and upland vegetation is well established, damage caused by typical levels of wildlife browsing and grazing should not negatively impact the trajectory of recovery of the system . Currently, we do not anticipate grazing by ungulates or rodent s to be a significant concern on this site. Site Maintenance Maintenance is the collection of actions taken to help ensure a given stream restoration project performs as designed and attains project objectives (Natural Resources Conservation Service, 2007). Maintenance is closely tied to management and involves the initial set of planned activities as well as unplanned activities following project implementation. Without any maintenance, substantial efforts may be required to correct failures in structures or other design elements. Active and frequent maintenance can often result in reduced “reconstruction” and “repair” costs down the road. Maintenance is most beneficial in the first three to five years following planting, apart from the occurrence of significant (i.e., 50 years or greater) flood events. Excessive flood flows soon after planting can cause substantial erosion and slope failure, resulting in unacceptable soil and plant loss. Such areas may need to be replanted, inter-planted, or reinforced by other means. Other maintenance efforts may include: (a) placement of large woody debris and other toe protection treatments on banks to redirect water away from the established areas, (b) repairs of in-stream rock structures, (c) invasive species management, (d) supplemental irrigation, and (e) fencing. Results from monitoring efforts will ultimately provide a list of recommended maintenance activities for Guardian Storage. Concluding Remarks Our intention in developing this adaptive management plan is to address the need to enhance ecological functionality, connectivity, and resilience. With an interdisciplinary team in place, and stemming from an understanding of management goals, it is our hope this plan will allow Guardian Storage Monitoring, Maintenance, and Adaptive Management Plan 17 | P a g e for adequate monitoring and possible maintenance necessary to support the restoration vision that led to the initial restoration design of Guardian Storage.
