CNHP Staff.\n\t<p>Since 1992, CNHP has partnered with public, non-profit, and private entities to conduct surveys of critical biological resources for counties and\/or watersheds. Many of these surveys have focused exclusively on wetland resources or combine wetlands with upland resources for a comprehensive assessment. The <strong><a href=\"https:\/\/cnhp.colostate.edu\/projects\/county-surveys\/\" target=\"_blank\" rel=\"noopener noreferrer\">county surveys<\/a><\/strong> are a primary source of data on Colorado&#8217;s biologically significant plants, animals, and natural plant communities. The data collected through these surveys are housed in our Biodiversity Information Management System (Biotics) database, which contains tens of thousands of records throughout Colorado and allows CNHP to rank and track areas of high biodiversity significance. Land managers rely on CNHP&#8217;s data to make informed decisions about the protection, <strong><a href=\"https:\/\/cnhp.colostate.edu\/cwic\/work\/conservation\/\">conservation<\/a><\/strong>, and <strong><a href=\"https:\/\/cnhp.colostate.edu\/cwic\/work\/restoration\/\">restoration<\/a><\/strong> of their natural resources.

The PCA ranks are designed to convey a list of prioritized lands to guide&nbsp;protection and conservation-a road map of conservation.

Denise Culver, CNHP. \n\t<p>The Big Creek Lakes PCA is located in northwest Jackson County. The lakes are within the Routt&nbsp;National Forest and flow into the North Fork of the North Platte River. The area surrounding Big Creek Lakes contains numerous closed depressions and kettle ponds formed over glacial till. The Big Creek Lakes area is one of the most extensive kettle pond areas known in Colorado. The vegetation of the kettle ponds occurs in successional zones from the open water to lake margins. Open water areas are dominated by water lilies and other aquatic plants. The herbaceous-dominated lake margins are dominated by mixed sedges, grasses, and rushes. Floating mats are found along the edges of the larger ponds that support a range of fen-obligate species such as bog sedge (<em>Carex limosa<\/em>), pale sedge (<em>Carex livida<\/em>), and extensive carpets of Sphagnum moss. This site is the only known location in Colorado that contains three rare amphibians: wood frog (<em>Lithobates sylvatica<\/em>), northern leopard frog (<em>Lithobates pipiens<\/em>), and a breeding population of the boreal toad (<em>Anaxyrus boreas<\/em>). The site also contains a very high concentration of state rare plants and several excellent occurrences of common wetland communities.<\/p>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cnhp.colostate.edu\/cwic\/wp-content\/uploads\/sites\/5\/2018\/11\/eriangustifolium-225x300.jpg\" alt=\"Tufts of tall cottongrass (Eriophorum angustifolium) can be found on in several fen complexes.\" height=\"300\" width=\"225\" title=\"eriangustifolium\">\n\t\t\t\t\t\tTufts of tall cottongrass (<i>Eriophorum angustifolium<\/i>) can be found on in several fen complexes.\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cnhp.colostate.edu\/cwic\/wp-content\/uploads\/sites\/5\/2018\/09\/Northern-Leopard-Frog_Keith_Penner.jpg\" alt=\"Northern leopard frog.

John Fielder.\n\t<p>High Creek is east of the Mosquito Range foothills in a depression at the base of several large glacial outwash fans that are fed by ground water flowing from the Mosquito Range through alluvial gravels. High Creek Fen is owned and managed by The Nature Conservancy of Colorado. This fen is the most ecologically diverse, floristically rich fen known in the Southern Rocky Mountains. It contains more rare plant species than any other wetland location in Colorado, and includes 14 plant species that are rare in Colorado. It is one of the largest and most intact wetlands left in South Park; other wetlands in the area have been destroyed or greatly altered by water diversions or peat mining. The site contains large populations of Canadian single-spike sedge (<em>Carex scirpoidea<\/em>) and few-flowered ragwort (<em>Packera pauciflora<\/em>) as well as excellent occurrences of two globally imperiled plant communities, <em>Kobresia myosuroides-Thalictrum alpinum<\/em> and <em>Kobresia simpliciuscula-Trichophorum pumilum<\/em>, and several other globally and state rare plants. It is the most extensive and highest quality example of extreme rich fens in all of South Park. It also contains nine rare aquatic and semi-aquatic macroinvertebrates not yet found at any other extreme rich fen. All but the upper, mined portion of the site is in very good condition, having been protected from most grazing impacts by the perennial high water table.<\/p>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cnhp.colostate.edu\/cwic\/wp-content\/uploads\/sites\/5\/2018\/11\/paleblueeyedgrass_hm_crop.jpg\" alt=\"Pale blue-eyed grass (Sisyrinchium pallidum) is found at High Creek Fen and other fen wetlands in Park County, CO.
