Using multispectral imagery and LiDAR data, we developed a high-resolution land cover dataset for a semi-arid, Colorado (USA) suburb. These data were used to evaluate patterns of land cover composition and vertical structure in relation to land use and age of development. Landsat 5 TM thermal band data for six separate dates were used to compare land surface temperature (LST) in urbanized and remnant...
Change in land surface temperature (LST) due to urbanization is a critical influence on the ecohydrological function and human health in cities. Past research has emphasized land cover composition and planimetric landscape pattern as drivers of LST patterns, but there have been few empirical studies examining the effects of vertical structure on thermal variation in cities. We used agglomerative cluster...
To be identified as a wetland under U.S. Federal regulations, a site must, under normal circumstances, support vegetation dominated by hydrophytes. A list of hydrophytes and their wetland indicator rating is published by the U.S. Army Corps of Engineers as the National Wetland Plant List (NWPL) and is the basis for assessing the vegetation criteria of Federal wetland delineation manuals. Ratings are...
To identify potential constraints on willow (Salix spp.) seedling establishment in montane riparian communities in Rocky Mountain National Park, Colorado, USA we established a controlled experiment to examine the effects of soil texture and elevation above river stage on willow seedling survival. We followed seedling survival rates over two summers in paired course- and fine-textured plots established...
