Monitoring wildlife using long‐endurance solar‐electric UAVs
Wildlife Biology, EarlyView.This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Implications of Restrictions on Imports of Canadian Softwood Lumber to the Southern Softwood Lumber Industry [PDF]
Review of Regional Studies, 1987 A number of policy options for the U.S. softwood industry are under consideration and there are indications that some form of restriction of the Canadian imports is imminent. The purpose of this paper is to evaluate the effects of trade restrictions and domestic subsidy on the southern softwood lumber industry.
