CX-019934: Tualatin SWCD Invasive Plant Management

Bonneville Power Administration (BPA) is proposing to allow Tualatin Soil and Water Conservation District (Tualatin SWCD) to survey for and treat – if found – invasive plants on BPA fee-owned right-of-way (ROW) in Washington County, Oregon. The proposed project would encompass two sites along the Keeler-Oregon City No. 2 transmission line: one site around Summer Creek between structures 14/4 and 14/10 and the other site around Bronson Creek between structures 6/8 and 6/10. The effort would target five species of invasive plant: garlic mustard (Alliaria petiolata), woody knotweed (Polygonum spp.), giant hogweed (Heracleum mantegazzianum), spurge laurel (Daphne laureola), and purple loosestrife (Lythrum salicaria).
