The Costs Of Birdstrikes To Commercial Aviation, John R. Allan, Alex P. Orosz Aug 2001

The Costs Of Birdstrikes To Commercial Aviation, John R. Allan, Alex P. Orosz

2001 Bird Strike Committee-USA/Canada, Third Joint Annual Meeting, Calgary, AB

Collisions between birds (and other wildlife) and aircraft are known to cause substantial losses to the aviation industry in terms of damage and delays every year. Techniques exist to control bird numbers on airfields and hence to reduce the numbers of wildlife strikes but they are applied at widely different levels from airport to airport. Some of this variation may be due to differing levels of strike risk at the different sites, but much of it is due to the unwillingness or inability of the airports concerned to invest in birdstrike prevention. Part of the reason for this reluctance to …


Black Bear Forest Damage In Washington State, Usa: Economic, Ecological, Social Aspects, Georg J. Ziegltrum, Dale L. Nolte Mar 2001

Black Bear Forest Damage In Washington State, Usa: Economic, Ecological, Social Aspects, Georg J. Ziegltrum, Dale L. Nolte

United States Department of Agriculture Wildlife Services: Staff Publications

Black bear (Ursus americanus) damage to coniferous forests can be detrimental to the forest products industry in Washington state. Value of timber damage, west of the Cascade Mountains is millions of dollars every year. The Washington Forest Protection Association’s (WFPA) Animal Damage Control Program (ADCP) manages bear damage in cooperation with the Washington Department of Fish and Wildlife (WDFW). Bears can significantly affect the viability of other wildlife, for example, elk (Cervus elaphus) calf predation on calving sites. Conversely, bear-damaged trees add to the snags and dead wood on the ground, which provide important habitat and …

History, Current Status, And Collaborative Researchprojects For Bemisia Tabaci, M. R. V. Oliveira, T. J. Henneberry, P. Anderson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Bemisia tabaci was described over 100 years ago and has since become one of the most important pests worldwide in subtropical and tropical agriculture as well as in greenhouse production systems. It adapts easily to new host plants and geographical regions and has now been reported from all global continents except Antarctica. In the last decade, international transport of plant material and people have contributed to geographical spread. B. tabaci has been recorded from more than 600 plant species and there may be many additional hosts not yet formally documented. Biotypes have been identified in different areas of the world …

University of Nebraska-Lincoln Extension: Historical Materials

Sugarbeet and sugarcane are the major sources of sucrose, a sweetener in a vast range of foods. Total world production of sucrose was estimated at 126,500 metric tons in 1998-1999 of which 37 percent was from sugarbeet and 63 percent was from sugarcane. This Extension Circular discusses the importance of growing sugarbeets and sugarcane in the states of Nebraska, Colorado, Montana, and Wyoming.
