The State Wildlife Action Plan (SWAP) is an expansive resource on the status of some wildlife populations in Colorado, with an emphasis on individual species and their habitats. The insights found in the SWAP will help CPW forge new partnerships, strengthen old ones and inform policy, keeping Colorado a hotbed of biodiversity.
The State Wildlife Action Plan (SWAP) is an expansive resource on the status of some wildlife populations in Colorado, with an emphasis on individual species and their habitats. The insights found in the SWAP will help CPW forge new partnerships, strengthen old ones and inform policy, keeping Colorado a hotbed of biodiversity.
The State Wildlife Action Plan (SWAP) was developed by experts at Colorado Parks and Wildlife (CPW) and Colorado Natural Heritage Program (CNHP), with input from many other partners. All U.S. states and territories update and publish a SWAP every 10 years. Regular revision allows states to revisit the priorities from the previous decade. SWAP revisions are required every 10 years to maintain eligibility for federal State and Tribal Wildlife Grants. CPW is fortunate to also receive funding from Great Outdoors Colorado (GOCO), the Species Conservation Trust Fund and other sources that support SWAP implementation. The DRAFT 2025 SWAP was submitted to the U.S. Fish and Wildlife Service (USFWS) in September 2025. It will be considered final after review and signature from the USFWS Director.

You can explore species and habitat profiles, threats affecting these resources, existing plans and monitoring efforts and conservation actions.
Find out moreThe Species of Greatest Conservation Need (SGCN) list is the centerpiece of the SWAP. During revisions, species can be removed, added or moved into a different ranking. The SWAP is a work plan for SGCN and addresses that specific suite of species. However, this will not limit CPW or our partners from continuing existing programs or developing new efforts to address other species. The SWAP does not provide any direct regulatory protections for SGCN. The SGCN list includes the species of animals and plants that most urgently need conservation action. The list was compiled and reviewed by mammologists, ornithologists, botanists, entomologists and other scientists at CPW and its partner organizations.
Each species’ ranking is based on how healthy its populations are, how critical Colorado populations are to the entire species' survival, how susceptible it is to existing and potential specific threats, and how much it would benefit from plausible conservation actions. Each SGCN is ranked in one of three tiers:
This tier lists the species that require conservation interventions most urgently.
Species that are in less danger, but still in need of active conservation.
This new subset of SGCN includes species for which more research is needed before we can fully assess its conservation need.

Success Stories
In the 1970s, there were only TWO active bald eagle nests in Colorado. Data collected in 2020 showed more than 300 nesting pairs of eagles in our state, triple the number of pairs in 2015. Through decades of dedicated conservation work, such as minimizing disturbances near eagles’ nests and winter habitats, and the efforts of Colorado Parks and Wildlife, the US Fish and Wildlife Service, the Bird Conservancy of the Rockies and various other organizations, eagle populations have grown significantly! Bald Eagles are no longer a SGCN — a success to celebrate as we continue to study this species.

Success Stories
In June 2024, the USFWS announced that it would not list the Rio Grande chub or Rio Grande sucker under the ESA. For several decades, CPW and multiple partners including federal agencies, states, Tribes, municipalities, non-government organizations and private landowners have worked to conserve the two species and implement long-term management actions to ensure their persistence. Following the 2014 petition to list these species under the ESA, CPW joined with multiple state and federal agencies, Tribal entities and other stakeholders throughout the species’ range to form the Rio Grande Chub and Sucker Conservation Team.

The location and relative condition of key habitats and community types essential to the conservation of each State's species of greatest conservation need. CPW and CNHP experts created maps that identify critical SGCN habitats. These maps reflect the distribution of each habitat, and include grasslands, forests and woodlands, wetlands and aquatic habitats, just to name a few.
Many habitats in Colorado benefit from high topoclimatic variability, with complex topography providing vegetation and species with microclimates that can enhance their ability to adapt to changing conditions. However, Colorado’s eastern plains and western desert areas are much flatter, potentially reducing their adaptive capacity. Colorado is highly exposed to the warming climate overall, and other habitat disturbances, departure from historic fire regimes, and invasive annual grasses all contribute to habitat-specific climate change vulnerability. Interacting climatic stressors also threaten resilience: in many of Colorado’s forest types, if catastrophic wildfires are followed by drought conditions, forest may not reestablish and type conversions to grassland or shrubland can occur. Most SWAP habitat types are considered moderately vulnerable to climate change.

Streams, rivers and natural lakes all fall into the aquatic habitat type. Their specific characteristics often vary based on location, creating different habitat communities within Colorado. Learn more about threats and actions for conserving aquatic habitats.
Forest ecosystems are complex habitats defined by their trees: a continuous strand of trees, with a closed or open canopy, is classified as a forest. The wildlife within forests depends on these trees for food and shelter. Over 60 species of greatest conservation need are known to use just the Pinyon-Juniper forest of Colorado.
Grasslands are made up of grasses and broad-leaved, herbaceous plants. They usually have very few or no woody plants and see warm growing seasons. Examples of grasslands are mixed and tallgrass prairie and shortgrass prairie.
The U.S. Environmental Protection Agency (EPA) defines wetlands as “areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season.” Riparian zones are the areas alongside a river or stream. These conditions support a unique set of wildlife species.
Shrubland, also called scrub, bushland or thicket, generally sees more rainfall than grassland or desert but less than forest. Short trees, or shrubs, constitute shrubland, and the habitat type often occurs on ridges and cliffs. Examples of shrubland include sandsage shrublands on Colorado’s eastern plains, saltbrush shrublands and sagebrush shrublands. Desert shrubland are grass-dominated areas with an open shrub layer.
A few habitat communities in Colorado do not fit neatly within any established habitat types. These communities fall into a miscellaneous “other” category. These include hot springs, sand dunes, agriculture, reservoirs, shorelines, mountains and canyons. Many of these habitats are smaller geographic scale, but are critically important to rare plants and other SGCN.
Conservation Spotlight
In 2024, Colorado House Bill 24-1117 gave CPW the authority to study invertebrates. Adding invertebrates to our scope has brought an exciting new opportunity to the agency to study the over 1,000 bee species, 300 butterflies and thousands of other invertebrates found in Colorado.
See below for information on overall threats and actions for invertebrates. Individual species assessments are underway and will be included here in the future.

One of the biggest challenges to the conservation of Colorado’s invertebrates is their sheer diversity. With 1,000 species of bees alone, the number of invertebrate species is immense, and giving each individual species a thorough treatment would be impractical. Invertebrates face many of the same threats as vertebrates and rare plants, including habitat loss and climate change. However, there are also a diversity of threats unique to invertebrates, some of which are poorly understood. Many of the invertebrate SGCN are threatened by a combination of local, regional and global factors. Any one species can be affected by different threats at different scales.
Examples of Threats
Bumble bees, while generalist pollinators, may be threatened locally by competition and disease spillover from domestic honeybees, but are declining regionally and globally in response to climate change and the increased use of insecticides.
Some species may face different threats at different life stages. Many butterflies, for instance, may rely locally on a specific plant to attach themselves to when developing inside a cocoon, making them vulnerable to any threats that that plant faces. But in adulthood, they depend on different aspects of their environment than they did as larvae, such as nectar sources, migratory routes and overwintering habitats.
Many aquatic invertebrates have extremely limited distributions; some occur in only a handful of locations. These small populations can face local
threats like cattle activity, pollution and invasive species, but also global threats like climate change.
Given that the threats invertebrates face are so diverse, the actions needed to address them are equally diverse. For most invertebrates, threats to habitats shared by a diversity of species are likely a good way to address habitat-driven declines.
Conservation Spotlight
The Wolverine was extirpated in Colorado in the early 1900s due to unregulated harvest and broad-scale carnivore poisoning. Wolverines, which number in the thousands in Canada and Alaska, have since reestablished populations in Washington, Montana, Idaho, and Wyoming, but have not repopulated Colorado. In 2024, the passage of SB24-171 gave CPW the authority to reintroduce the North American wolverine to Colorado. The species and this restoration effort will be a very high priority for CPW. Colorado’s high snowy mountains are the species’ largest unoccupied territory in the lower 48 states, and will only become more important as a warming climate shrinks the snow and cold wolverines need. Colorado’s mountains, which are at high elevation, are predicted to retain their snowpack as well, if not better than, the lower-elevation mountains in the Northern Rockies and Cascades.

Conservation Spotlight
In 2024, Colorado House Bill 24-1117 gave CPW the authority to study plants.
The Rocky Mountain monkeyflower is a rare plant endemic to Colorado, meaning it’s found here and nowhere else on Earth. Individual plants reproduce by growing identical, bud-like clones on their leaf stems; these tiny buds then fall off and grow into new plants. Clonal reproduction results in very low genetic diversity in this species, making it slow to adapt to changes in its environment.
CPW’s conservation efforts are designed with these vulnerabilities in mind. CPW-funded studies have increased monkeyflower populations, making the species more resilient to small, but destructive, events. In these studies, conducted in the 2010s, researchers introduced bulbils from greenhouse-grown monkeyflowers into promising new habitats. Many of these patches have persisted — sprouting up plants that produce a new, successful generation of bulbils, year after year — for nearly a decade.

The term “threat” relates broadly to factors that negatively impact species or habitats. In the SWAP, the intent is to discuss stressors or problems that are directly or indirectly posing risks with consideration that these impacts are dependent on the species, habitat, timing, intensity and more. What is considered a threat to one species or habitat may help another. What is a management tool to provide habitat for one species could be detrimental to another. Some threats to species and habitats may benefit humans. Threats are also variable by specific location and generally can’t be defined at a statewide scale.
The use of land and water may threaten species and habitats:
The use/management of species
By considering exposure to projected environmental changes (e.g., warmer temperatures), sensitivity to those changes and a given entity’s adaptive capacity to handle changes, climate change vulnerability assessments identify which species or habitats are most vulnerable to the impacts of climate change.
The robust planning process for the 2025 SWAP set Colorado up for implementation of a thorough statewide plan for SGCN and their habitats. But, this is just the beginning. The intent is to begin a decade of collective action with opportunities to increase awareness of the SWAP and engage in more specific efforts. How can conservation practitioners reduce “random acts of conservation” to best leverage scarce resources? SWAP should drive work and provide guidance on what is needed to impact conservation. In the coming years, CPW will develop ways to track progress on conservation efforts for SGCN and their habitats. We hope you will be a part of this important work.
