Effects of weed control on vegetation dynamics in Pacific Northwest conifer plantations

Creator:

Chen, Fen-Hui

Abstract:

Weed control in Pacific Northwest forests has been criticized for its potential impact on biodiversity. Changes were evaluated in conifer growth, diversity of vegetation in situ and of recruiting plants through different regeneration mechanisms after applying temporally-varied weed control by herbicide treatments based on the critical period concept. Conifer size...

The phytotoxic effects of herbicide and adjuvant application by physiological timing on the woody shrub salal (Gaultheria shallon)

Creator:

Downs, Theodore

Abstract:

Salal is plant species that is native to forestland throughout the PNW and northern California that has been identified as a competitor to early crop tree development. This study consisted of a field and a radioisotope laboratory study to test four commonly used herbicides on salal (imazapyr, triclopyr, glyphosate, and...
