Abstract
From 1977 through 1986, herbage and browse production was sampled on 619 sites representing 10 ecosystems and 51 resource units on the Oregon Range Evaluation study area. We determined the effects of six range management strategies and cultural treatments on combined herbage and browse production. Mean herbage and browse production on the forest ecosystems was 145 kilograms per hectare and ranged from 53 to 194 kilograms per hectare. On the range ecosystems, production averaged 417 kilograms per hectare and ranged from 224 to 1037 kilograms per hectare. Production for strategies among forest ecosystems ranged from 59 to 272 kilograms per hectare, and among the range ecosystems it ranged from 337 to 636 kilograms per hectare. Cultural practices increased production on all sites except one, and the increases were significant (p = 0.2) in 8 out of 17 cases.
