Additions to the Vascular Flora of South Central Iowa

A field survey of Warren County made during the months of April, May, and June of 1962 identified over 200 collections of flowering plants. During the fall of 1962 a survey of the Red Rock Dam area identified over 50 collections of flowering plants. Simpson College Herbarium specimens of these areas were carefully checked and annotated. In these collections, 17 species were found that had not been previously published for these areas

Estimating Plains Pocket Gopher Abundance on Adjacent Soil Types By A Revised Technique

A measuring wheel proved useful as an aid for counting signs of the plains pocket gopher (Geomys bursarius) on adjacent soil types in Washington County, Colorado. Signs of pocket gophers were about twice as frequent on the Haxton Sandy Loam type as were signs on the Dune Sand type. There were progressively more signs from spring until autumn. About 7.5 times more signs were observed on each area in September than in May.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Remote Sensing Documentation of Historic Rangeland Remediation Treatments in Southern New Mexico

The Jornada Experimental Range and the New Mexico State University Chihuahuan Desert Rangeland Research Center are fruitful areas to study the long-term effects of rangeland remediation treatments which started in the 1930s. A number of diverse manipulations were completed under the direction of federal agency and university scientists, and abundant remote sensing imagery is available to assist in relocating the treatments and evaluating their success. This is particularly important because few of the treatments were maintained following the loss of scientific personnel coinciding with the start of World War II, and most records of Civilian Conservation Corps scientific work were lost with the disbanding of the agency in 1942. Aerial photography, which was systematically used to image the United States beginning in the 1930s, can be used to identify types of treatments, measure areal coverage, estimate longevity, and help plan locations for new experiments. No long-lasting vegetation response could be determined for contour terraces, brush water spreaders, strips grubbed free of shrubs (despite the fact that these strips have remained visible for 65 years), and mechanical rootplowing and seeding. Distinct positive, long-term vegetation responses could be seen in aerial photos for water retention dikes, certain fenced exclosures, and some boundaries where different land management practices meet. It appears from both aerial photos and existing conventional records that experimental manipulation of rangelands has often been ineffective on the landscape scale because treatments are not performed over large enough contiguous areas and hydrological and ecological processes overwhelm the treatments. In addition, treatments are not maintained over time, treatment evaluation periods are sometimes too short, multi-purpose treatments are not used to maximize effects, and treatments are often not located in appropriate sites
