SpreadStop tHEThese invasive plants are found in the Birds Hill
Ecoregion and may
be on your land, threatening pastures, hay fields and native
habitats. They out-compete both native plants and forage crops
and some are toxic to livestock.please take action early to
avoid further spread!

Spot &ControlInvasive plants are spread by vehicles,
equipment, animals, and on
your clothing. Learn how to spot invasives early and how to
eliminate them on your land using a combination of control
methods.
For more control tips, where to report, and maps that monitor
the spread visit www.BirdsHillEcoregion.com
These plants, though visually appealing, are invasive pests
outside the garden out-competing and replacing field, forage
and
native plants. Avoid planting in the garden and report sightings
early to avoid further spread!
Physical and organic methods include hand-pulling (use gloves),
mowing before seed set, ploughing or tilling, mulching, controlling
plants access to water, rotating crops or, for leafy spurge,
grazing sheep and goats. Mowing alone does not work. Seal
hand-pulled plants in black plastic garbage bags and let the bags
sit in the sun for a couple of weeks before disposal.
Herbicides are chemicals used to destroy or inhibit plant
growth. It is important to use the right herbicide for the job and
follow product labels; incorrect use of herbicides will result in
poor weed control and can create larger problems. Please contact
your local weed supervisor for advice and respect your local
laws.
Biocontrol is the introduction of natural enemies into the
environment in order to interrupt the spread of unwanted pests (ex.
leafy spurge flea beetles) and is typically used as a support of
other methods against large infestations.
Spot and Report invasive species to participate in province wide
action to minimize their economic and environmental impacts.
