    • An Experiment in Deer Detection by Thermal Scanning

      Parker, Dennison H.; Driscoll, Richard S. (Society for Range Management, 1972-11-01)
      An airborne, thermal infrared scanner was tested for deer detection over penned mule deer (Odocoileus hemionus hemionus) near Fort Collins, Colorado. The animals were detected at 300- and 500-ft altitudes, but not at 1,000 ft.
    • An Alternate-Furrow System for Seeding Northern Colorado Rangeland

      McGinnies, W. J. (Society for Range Management, 1972-11-01)
      The most successful method for seeding cool-season grasses on northern Colorado rangelands has been to plant with a drill in the spring on a smooth, fallowed seedbed. However, wind erosion may destroy a level-drilled seeding. Planting in deep furrows has resulted in poorer stands, but the deep-furrows appear to be necessary for control of wind erosion. A system is proposed for alternating deep-furrow drilling with level-drilling on the beds between the furrows in order to combine the erosion control benefits on the deep-furrows with the better stand establishment characteristics of the level-drilled planting.
