The paper traces the manner in which an obligation came to be imposed on select industries, requiring them to take account of amenity, wildlife and outdoor-recreational interests in the course of preparing and carrying out developmental schemes. Under pressure from the relevant voluntary bodies, the statutory obligations, first imposed on hydro-electric power development, were generalized to cover 'whole' industries, and then, under the Countryside Acts of 1967-68, were extended to all State utilities. The recent privatization of those industries has provided a further pretext for extending and strengthening the 'amenity' clause. The approach has provided important insights into how industry itself might become...
Woodland caribou (Rangifer tarandus caribou) in Alberta are classified as endangered and apparently have declined. Disturbance from petroleum exploration has been implicated as a possible cause, so we constructed a simple model to estimate the energy costs of multiple encounters with disturbance (i.e., loud noise). Our objective was to estimate if woodland caribou in northeastern Alberta have been exposed to enough disturbance from 1988 to 1993 to cause winter mass loss to exceed either (i) 15% autumn mass or (ii) 20% autumn mass. A single disturbance event costs caribou 3.46-5.81 MJ. Caribou would have to encounter (i) 20-34 (mean = 27) disturbance events to lose >15% mass over winter and (ii) 41-137 (mean = 89)...
Bureau of Land management shape file depicting Oil and Gas lease Areas in Utah, USA This data set contains Oil and Gas Leases, derived from Legal Land Descriptions (LLD) contained in the US Bureau of Land Management's LR2000 Database, and geocoded (mapped) using the Public Land Survey System (PLSS)/Geographic Coordinate Data Base (GCDB) derived from the most accurate survey data available through BLM Cadastral Survey workforce, and the Premier Data Services CarteView Software.
