Degener's penstemon (Penstemon degeneri) is a perennial herb in the Plantaginaceae (Plaintain Family) that is found only in Fremont, Custer and Chaffee counties, and is considered to be imperiled at a global and state level. When flowering, it has beautiful blue-purple flower spikes. 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.
This report includes a summary of the results of the past ten years of population monitoring of targeted noxious weeds at the U.S. Air force Academy, emphasizing changes that were observed between 2012 and 2016.
Pagosa bladderpod (Physaria pruinosa=Lesquerella pruinosa) is a small, rosette-forming, yellow-flowered plant in the Brassicaceae (Mustard Family) that is known only from two counties in southern Colorado and one county in northern New Mexico. 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.
Decreases in the abundance, distribution and diversity of animal species in recent decades have been widely documented as species have responded to land-use pressures such as urban expansion, the alteration of habitat structure from the spread of nonnative plants and climate change. The City of Boulder Open Space and Mountain Parks (OSMP) has been surveying butterfly communities in 18 transects in five different years. The goal of this document is to determine how butterfly communities have changed over time, with reference to habitat type, time, and their interaction.
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.
Golden blazing is a tall plant, with thick stems, and attractive, 10-petaled bright yellow flowers. Golden blazing star is found primarily on the Smoky Hill member of the Niobrara shale, in the middle Arkansas Valley, in Fremont and Pueblo counties, Colorado, and nowhere else in the world. Golden blazing star 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.
Pueblo goldenweed (̲Onopsis puebloensis) is a yellow flowered plant in the Asteraceae (Sunflower Family) that is known only from the Arkansas Valley in Pueblo and Fremont 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. The Best Management Practices included in this document are intended to help increase the awareness of this species for o help increase the awareness of this species for anyone involved in road maintenance activities.
Piceance bladderpod is a low, rosette-forming, yellow-flowered plant in the Brassicaceae (Mustard Family) that is found chiefly on outcrops of the Green River Shale Formation in the Piceance Basin. It grows on ledges and slopes of canyons in open area of pinon juniper communities.
Colorado supports habitat for approximately 120 globally imperiled plant species. These plants are in need of conservation attention to prevent unnecessary extirpations and extinctions. Numerous populations of these globally imperiled plants are known from roadside locations in Colorado. 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.
Cushion bladderpod (Physaria pulvinata) is a low, compact plant in the Brassicaceae (Mustard Family) It is densely matted and hairy, less than 3 dm across with 4-petaled yellow flowers. It is known from widely scattered outcrops of grayish Mancos shale in San Miguel and Dolores 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.
This report and associated dataset provide the MLSNF with a critical tool for conservation planning at both a local and Forest-wide scale. These data will be useful for the ongoing MLSNF biological assessment required by the 2012 Forest Planning Rule, but can also be used for individual management actions, such as planning for timber sales, grazing allotments, and trail maintenance. Wherever possible, the Forest should avoid direct disturbance to the fens mapped through this project, and should also strive to protect the watersheds surrounding high concentrations of fens, thereby protecting their water sources.
