Summary of Methods: This study was designed to quantify the amount of regrowth occurring on a stream-associated riparian zone, in southeastern Oregon, following defoliation. There was very little regrowth of the riparian community when clipping occurred after mid-July. Temperatures during 1993 were well below normal, which is reflected in the fact that total standing crop peaked with the August treatment, rather than with the July treatment as in 1994 and 1995. The existing beaver dam may explain the relatively high total production in 1994 (a drought year) and 1995, compared to 1993. Managers should be cautious in their assumptions about regrowth in riparian areas. It has often been assumed that because riparian areas are relatively wet, they will regrow vigorously. The amount of regrowth will undoubtedly depend on the plant community, elevation, and the hydrology of the site. However, under the conditions of this study, significant regrowth after mid-summer would not be expected.

Annotation: During 1993 and 1994, the three clipping treatments were clipped once during the growing season, either mid-July, mid-August, or mid-September. All treatments were also clipped in mid-October to assess standing crop of the unclipped control or regrowth of previously clipped treatments. The standing crop was clipped to a 1.0 inch stubble height.
