In February, the County Public Works department made an ill-conceived and disastrously prepared application for a special use permit for an industrial-scale composting facility on county open space at the site of the former Rainbow Tree Nursery Site, east of US 287 and north of Lookout Road.

April Nature Almanac: Bluebirds Make Our Hearts Sing

How did bluebirds acquire their dazzling color? Once upon a time, according to folklore, all the birds and animals were painted but one. The forgotten bird flew up into the sky to protest its drab coat, and bits of sky stuck to its feathers. Today, we still thrill to see that dazzling color whenever we see a bluebird.

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.
