At the state level, depending on the election results, we may be looking towards active reintroduction of the gray wolf, which is currently almost extirpated in Colorado. In the next few months we may also see resolution of some issues regarding management of Greater Prairie Chickens on State Land Board properties in southeast Colorado, which are being pursued by the Audubon Colorado Council.

Teen Naturalists Uncover Tallgrass Treasures

When international documentary filmmaker Yan Chun Su offered to lead a filmmaking workshop for our Boulder County Audubon Teen Naturalists, we had no idea what they would come up with. None of the students had ever attempted videography, and many were just beginning to experiment with close-up photography.

Over the last few decades, the Boulder County Commissioners have been particularly astute in creating oil and gas regulations that provide maximum health and environmental protections without overreaching and provoking court rulings that would limit their flexibility and authority.

In the time of the novel coronavirus, decision-making bodies on local environmental issues are all on hold while local and state governments concentrate on those parts of the crisis for which they have to assume responsibility.

Black-tailed prairie dogs once occupied a territory hundreds of miles wide, stretching from Mexico to Canada. We have now converted nearly all of that grassland to cropland for wheat, corn, other crops; pastures of European grasses; or paved it over for homes and shopping centers. We also introduced sylvatic plague (bubonic plague in humans), a disease that did not exist in North America and for which prairie dogs are not evolved to deal with.

Fluctuating Numbers of Wintering Raptors Reflect a Cold Northern Winter and a Locally Fractured Environment

Since 1983, volunteers with the Boulder County Nature Association have monitored winter raptors. Volunteers driving six survey routes throughout the plains of Boulder County detected more wintering raptors during 2018-19 than had been seen during any previous fall-winter season (15 October-15 March) of the 30-year study.

Reflections on a First Season of Bluebird Box Monitoring

This summer was a first for me; my family and I volunteered as Wildlife Monitors for the Boulder County Parks and Open Space Bluebird Nest Box Monitoring Program!

BCAS Teen Naturalists Inventory Raptors, Conduct Breeding Bird Surveys, and Photograph Wildlife

Boulder County Audubon teen naturalists inventoried raptors along the Rabbit Mountain Survey Route, counting a total of 56 eagles, hawks, and falcons during a single morning; toured the Birds of Prey Rehabilitation Foundation flight cages in Broomfield; photographed courting ducks at Wheat Ridge Greenbelt; and contributed enthusiastically to the Boulder Christmas Bird Count.

Cultivating Untidyness

Biologists talk about diversity in terms of both species diversity, the number and kind of species found in a particular area, as well as structural diversity, the form of the community. A typical yard with lawn, raked flower beds, and specimen shade trees is not diverse by either measurement. It may be tidy, but it provides habitat for very few native species.
