A simple classification of soil types as habitats of biological soil crusts on the Colorado Plateau, USA
Question: Can a simple soil classification method, accessible to non-experts, be used to infer properties of the biological soil crust (BSC) communities such as species richness, evenness, and structure? Location: Grand Staircase-Escalante National Monument, an arid region of the Colorado Plateau, USA. Methods: Biological soil crusts are highly functional soil surface communities of mosses, lichens and cyanobacteria that are vulnerable to soil surface disturbances such as grazing. We sampled BSC communities at 114 relatively undisturbed sites. We developed an eight-tier BSC habitat classification based upon soil properties including texture, carbonate and gypsum content, and presence of shrinking-swelling clays....

Non-native plant invasions in managed and protected ponderosa pine/Douglas-fir forests of the Colorado Front Range
We examined patterns of non-native plant diversity in protected and managed ponderosa pine/Douglas-fir forests of the Colorado Front Range. Cheesman Lake, a protected landscape, and Turkey Creek, a managed landscape, appear to have had similar natural disturbance histories prior to European settlement and fire protection during the last century. However, Turkey Creek has experienced logging, grazing, prescribed burning, and recreation since the late 1800s, while Cheesman Lake has not. Using the modified-Whittaker plot design to sample understory species richness and cover, we collected data for 30 0.1 ha plots in each landscape. Topographic position greatly influenced results, while management history did not. At...
