Gunnison Sage Grouse Conservation Easement in Dove Creek, CO
In 2006, CNHP collaborated with Colorado Parks and Wildlife
biologist to create the Dove Creek Potential Conservation Area (PCA) in
southwestern Colorado. This PCA was drawn to identify habitats that support one
of the seven remaining populations of the federally listed Gunnison
sage-grouse. As of 2014, this population (referred to as the Monticello-Dove
Creek population) contains only 98 individuals, according to the final listingrule issued by U.S. Fish and Wildlife Service. Lek count data from 19 years of
monitoring are generally well below the Rangewide Conservation Plan population
target of 500 breeding birds.
In recent years, in an effort to reverse the population
trend, Montezuma Land Conservancy has worked with private landowners to
conserve important sage-grouse habitat with conservation easements. Since
2012, the Conservancy has conserved 3,340 acres of occupied habitat for the
Gunnison sage-grouse – 2,700 of which is located within the CNHP Dove Creek PCA. The most
recent project protected approximately 680 acres of the Dove Creek PCA under a
conservation easement. The property contains sagebrush habitats, as well as
areas formerly used to grow dryland pinto bean crops which have been replanted
into sage brush. The conservation easement contains a total of 788 acres,
and borders BLM land and the Coalbed Canyon State Wildlife Area.
Sagebrush habitats and former pinto bean cropland near Dove Creek, Colorado offer habitat for Gunnison sage-grouse, a species listed as threatened in 2014 by the U.S. Fish and Wildlife Service. |

CNHP Director Attends Plant Conservation Alliance Meeting in Washington, D.C.
CNHP director David Anderson recently attended meetings in Washington, D.C. organized by the Plant Conservation Alliance (PCA). The PCA is a public-private-agency partnership of organizations that work to maintain, enhance, and restore native plant populations and communities. Anderson worked with other non-federal cooperators during the meeting to identify strategies for plant conservation. He presented information on the addition of rare plants to the Colorado State Wildlife Action Plan (SWAP), as well as the Rare Plant Conservation Initiative project that helped prompt this exciting addition to the Colorado SWAP. Crafting a bill to create a National Plant Conservation program was the primary strategy identified by the group. Anderson, along with other PCA members, also met with members of the appropriations committees and federal agency leaders to discuss plant conservation, including the National Seed Strategy. After the Strategic Planning Meeting, Anderson was able to participate in a tasting of botanical spirits hosted by the United States Botanical Garden and led by Dwight Grimm. Grimm is a vermoutheir and founder of the Little Alchemist Farm. He produces small-batch herbal spirits, elixirs, and oils from his farm in Preston Hollow, New York.

Is your Phragmites native?
If you work in wetlands, you have no doubt marveled at the spectacular common reed (Phragmites australis). This grass can tower over a field biologist, growing up to 15 ft tall. It is frequently found along streambanks and ditches in Colorado. Often considered an aggressive non-native, recent development of molecular markers has led to the discovery that both native and introduced genotypes exist in North America. This evidence suggests that land managers should think twice before treating common reed like an invasive weed.
It can be difficult to determine native vs. introduced Phragmites using morphological characters. Luckily, Dr. Bernd Blossey has created a handy guide to help distinguish between them. If looking at this table makes you dizzy, the website also offers a free diagnostic service. Send them your common reed specimen, and they will key it out for you! Crystal Strouse, Fort Collins Natural Areas botanist, recently suspected that a population of Phragmites at Running Deer Natural Area was native. After sending material to Bernd Blossey, it was confirmed that the Running Deer population belongs to the native genotype of common reed. At CNHP, we plan on making more collections of this species during the 2015 field season to help determine how common the native genotype is in Colorado.
