Ivy |
This project is a small understory planting along a forested stream in the Middle Fork watershed. The landowners have been managing the site, focusing on controling an English Ivy problem. The project was designed to restore native understory to the rapairian zone. Blackbarry was removed and replaced with thimbleberry, snowberry, and ninebark. The meandering Lost creek easyly floods and replishes the already rich soils. However, less established plantings are at risk to floodwash damage. The 2005-06 highwater events had not only washed some young shrubs away but ripped 2005 tags off the remaining shrubs.
The Ivy Site is a shrub planting project.
