This work may be completed with ars excavator. 3. As instructed by the project biologist, remove non-native plants including Himalayan blackberry and the root mass of any Bohemian knotweed. Haut Bohemian knotweed to landfill for disposal. This work may he completed with an excavator. Protect native trees growing near the streani, being careful to leave their root systeins undisturbed. 4.
