An Experiment in Deer Detection by Thermal ScanningAn 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 RangelandThe 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.
