Outplanting Survival of Bartonberry (Rubus bartonianus)

EXECUTIVE SUMMARY

From November 14-17, 2016, we outplanted 2173 individual Bartonberry (Rubus bartonianus) seedlings into 3 locations in Hells Canyon. The sites were located near the Baker and Wallowa County boundary, with the Reservoir and Copper Creek sites adjacent to the Snake River and the Hess Road site located in the Ashby Creek drainage southwest of the other sites. We planted 1124 seedlings at the Reservoir site, 866 seedlings at the Hess Road site, and 183 seedlings at the Copper Creek site. From May 23-25, 2017, we monitored survival of outplanted Bartonberry seedlings at the 3 locations.

• Proportion of plants remaining during surveys in 2017 ranged from 20-89%.
• Copper Creek had the highest proportion of plants remaining in 2017.
o Of the 183 plants originally planted in fall 2016, 131 were still actively growing the following spring.
• The Reservoir site had 492 plants recorded in 2017, from the 1124 planted in fall 2016.
