• Construction and Use of an Inexpensive Rain Gauge

      Ohlenbusch, P. D. (Society for Range Management, 1972-09-01)
      An inexpensive, wind-proof rain gauge was devised for measuring precipitation at remote locations. The gauge can be constructed from a funnel, gasoline can and assorted lumber and metal. Gauges in use over one year have withstood winds in excess of 50 miles per hour. Ease of installation and minimal maintenance requirements make the gauge desirable for remote or inaccessible locations that are visited infrequently. Protection from livestock may be necessary if rubbing is a problem.
    • Whitelined Sphinx Moth Larvae on Rangeland Vegetation

      Mock, D. E.; Ohlenbusch, P. D. (Society for Range Management, 1981-09-01)
      Larvae of whitelined sphinx [Hyles lineata (Fab.)] caused heavy defoliation and other injury to several species of range plants in a newly seeded stand of brome grass [Bromus inermis Leyss.] near Lakin, Kearny County, Kansas. Although larvae of this species are rather general feeders on broadleafed plants, they had a sequence of preference and completely ignored the brome grass. Species commonly eaten included prairie evening-primrose [Oenothera albicaulis (Pursh)] and spotted beebalm [Monarda punctata L.]. It is conjectured that feeding by whitelined sphinx larvae may sometimes influence the composition of range plant communities on the short grass prairie of the North American Great Plains.
