This report presents a summary of the most recent inventory information for Colorado's forest lands. The report includes descriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals. Most of the tables are organized by forest type, species, diameter class, or owner group. The report also describes inventory design, inventory terminology, and data reliability. Results show that Colorado's forest land totals 23 million acres. Nearly 50 percent of this forest land is administered by the USDA Forest Service. Pinyon-juniper forests cover over 5.5 million acres whereas forest comprised of fir, spruce, and hemlock comprise 24 percent of Colorado's forest land. Aspen is the single most abundant tree species in Colorado. Net annual growth of all live trees 5.0 inches diameter and greater on Colorado forest land totaled 219.6 million cubic feet. Average annual mortality totaled nearly 421.0 million cubic feet.

Birds are indicators of vegetation structure and ecological conditions. The singing activity of birds declines during late-morning periods, which can affect estimates of abundance and conclusions regarding vegetative conditions indexed by birds. Therefore, it is important to quantify periods of bird activity so biologists can plan studies. We determined hourly detections from singing males of 22 nongame bird species in ponderosa pine, quaking aspen, and grassland vegetation types in the Black Hills of South Dakota. Detections of 12 of 22 species differed among 1-hr intervals after sunrise. Detections of yellowrumped warblers, Townsend's solitaires, red-breasted nuthatches, western tanagers, and American robins decreased on count-episodes more than 4 hrs after sunrise. Detections of dusky flycatchers declined on count-episodes more than 3 hrs after sunrise and detections of black-capped chickadees were greatest during the first hour after sunrise and declined afterward. Detections of many other species from songs or calls decreased on count-episodes more than 5 hrs after sunrise. We recommend that bird counts in the Black Hills be completed within 4 hrs after sunrise so estimates of bird abundance are not affected by reduced singing among males.

In Building a Resilient Twenty-First-Century Economy for Rural America, Don E. Albrecht visits rural communities that have traditionally been dependent on a variety of goods-producing industries, explores what has happened as employment in these industries has declined, and provides a path by which they can build a vibrant twenty-first-century economy. Albrecht describes how structural economic changes led rural voters to support Donald Trump in the 2016 election and why his policies will not relieve the economic problems of rural residents. Trump’s promises to restore rural industrial jobs simply cannot be fulfilled because his policies do not address the base cause for this job loss—technological change, the most significant factor being the machine replacement of human labor in the production process. Bringing a personal understanding of the effects on rural communities and residents, Albrecht focuses each chapter on a community that has traditionally been economically dependent on a single industry—manufacturing, coal mining, agriculture, logging, oil and gas production, and tourism—and the consequences of losing that industry. He also lays out a plan for rebuilding America’s rural areas and creating an economically vibrant country with a more sustainable future. The rural economy cannot return to the past as it was structured and instead must look to a new future. Building a Resilient Twenty-First-Century Economy for Rural America describes the source of economic concerns in rural America and offers real ways to address them. It will be vital to students, scholars, practitioners, community leaders, politicians, and policy makers concerned with rural community development.
