Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley May 1974

Economic Feasibility Of Controlling Big Sagebrush (Artemisia Tridentata) On State And Private Rangelands In Utah, Stan D. Hinckley

All Graduate Theses and Dissertations

Spraying with the chemical herbicide 2,4-D is the most widely used method of controlling big sagebrush. Spraying is very effective in increasing forage production and generally is not poisonous to either man or animals.

Two procedures can be used to calculate the internal rate of return to big sagebrush control: standard and modified discounting. Standard discounting assumes all nonuse costs are incurred in the year of treatment, and the annual income stream is constant throughout the effective life of treatment. Modified discounting correctly assumes the nonuse cost is incurred in the period of deferment, and the income stream does ...

Economic Rent Values For Pheasant Hunting In Utah, Braulio Rodriguez V. May 1971

Economic Rent Values For Pheasant Hunting In Utah, Braulio Rodriguez V.

All Graduate Theses and Dissertations

A conceptual model relating recreation resource values to the concept of economic rent was developed. The model argues that recreation sites possess both quality and location characteristics which serve as rent producing agents. Sites of better quality extract economic rents relative to those of lesser quality while those located most advantageously to user origins earn location rents relative to those more distantly located. The economic rent values are expressed by the differential use costs and recreationist activity associated with individual site usage.

A methodological procedure was developed which generates estimates of total rent values for a given site. The procedure ...
