This report details a strategy for control of invasive plants found at nine military installations located along the Front Range of Colorado and Wyoming. Invasive plant species control plans have been written for six of the nine installations. These plans suggest which weeds are top priorities for control at each installation. They also have specific on-the-ground control recommendations for each noxious weed species that has been documented at the installation. They detail a combination of control options including pulling, mowing, cutting, burning, using biological control methods with insects/pathogens, grazing, and using herbicides.
Seventeen globally imperiled plants found in oil and gas development areas in Colorado are in danger of extinction. Collectively, these species occupy less than 11,000 acres in Colorado. One of the biggest conservation issues for Colorado native plants is the lack of awareness of the existence and status of these rare plant species. Avoiding or minimizing impacts to these species during oil and gas development activities may help to effectively conserve their habitat and is unlikely to confer substantial impacts on oil and gas development projects.
Round-leaf four o'clock (Oxybaphus rotundifolius) is a medium-tall plant in the Nyctaginaceae (Four o'clock Family) that is restricted to barren shale outcrops of the Smoky Hill Member of the Niobrara Formation in sparse shrublands or woodlands and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
Rabbit Ears gilia (Ipomopsis aggregata ssp. weberi) is a tall herbaceous plant in the Polemoniaceae (Phlox Family) that is known from north central Colorado in Grand, Jackson, and Routt counties, and is also found in northern Idaho and south central Wyoming and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
Bell's twinpod (Physaria bellii) is a small, yellow-flowered plant in the Brassicaceae (Mustard Family) that is known only from the Front Range in Boulder and Larimer counties, Colorado, and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
Good-neighbor bladderpod (Physaria vicina) is a small plant in the Brassicaceae (Mustard Family) that is known only from southwestern Colorado in Montrose and Ouray counties, and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
Brandegee wild buckwheat (Eriogonum brandegeei) is a mat-forming plant in the Polygonaceae (Buckwheat Family) that is known only from the Arkansas Valley in Fremont and Chaffee counties, Colorado, and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
Arkansas Canyon stickleaf (Nuttallia densa) is a small, yellow-flowered, subshrub in the Loasaceae (Blazingstar Family) that is known only from the Upper Arkansas River Basin in Fremont and Chaffee counties, Colorado, and is considered to be imperiled at a global and state level. One of the biggest conservation issues for this imperiled plant species is the lack of awareness of its existence and status. Avoiding or minimizing impacts to this species during road maintenance activities will effectively help to conserve its habitat and is unlikely to confer substantial impacts on road maintenance goals and projects.
