Creator:: Wells, Micah
Abstract:: Two studies were conducted to determine the factors influencing distribution of cattle on northeastern Oregon mixed-conifer forested rangelands. The objective of the first study was the quantification of differences in distribution of cattle of different ages. Beginning in 1991, and continuing through 2001, radio telemetry collars were placed on a...

Creator:: Alejandro-Castro, Mabel
Abstract:: The ability of controlled livestock grazing, in combination with seeding of palatable forages, to reduce understory competition and enhance conifer establishment, was evaluated during 1985 and 1986, on two adjacent sites in southwestern Oregon. In 1984, Site 1 was clearcut and broadcast burned to remove slash, and Site 2 was...

Abstract:: A study to determine possible impacts of cattle and big game grazing on streamside erosional responses was initiated in 1975. The objectives of the study were to: (1) establish the study and collect base line measurements; (2) determine the impact of animal grazing on soil bulk density and erosional potential,...
