Habitat & Ecology

The Fraser Valley has some large infestations of Wild Chervil along highway rights-of-way. It prefers wet conditions and disturbed soils. It grows in mid to low elevations on roadsides, pastures, forest edges and fence lines.

Impacts

It will compete with pasture and hay crops reducing its quality. It will compete with other plants for nutrients, water and can out complete other plants for space. It is well-adapted to wet areas so stream banks, river edges, ditches and wetlands are at risk for introduction and spread.

Management

This plant is difficult to control because of its deep root system. Mowing can also cause it to establish and spread. Rosettes and small plants can be hand-pulled and dug out. Mature plants, however must have all of the plant removed including the extensive root system to have any success. Please contact LRISS for all other treatment information.
