Weed Management - Preventing
noxious weeds
Prevention
& early detection
Preventing noxious
weeds from establishing in the first place is the most effective
and least costly method of weed management. It is important to identify
high-quality and valued areas - areas with high desired plant cover,
areas that are relatively free of weeds - and protect them from
weed establishment. Preventing establishment can be accomplished
by:
- Limiting
weed seed dispersal
- Detecting
and eradicating weeds early
- Revegetating
when necessary, and
- Properly
managing desired plants to prevent invasion.
Limiting
the dispersal of weed seeds
Preventing or
greatly limiting seed dispersal is an important component in minimizing
the introduction or spread of weeds. Seed dispersal can be reduced
by those actions listed in the slide show:
Detecting
& eradicating weed introductions early on
Early detection
of new weeds through monitoring is crucial in preventing their establishment.
Incorporating a systematic monitoring program within a burned-area
IWM plan permits the early identification and eradication of new
weeds and small patches.
Formulating
a monitoring plan
Surveying and
eradicating new weeds through a methodical, organized monitoring
plan is essential to prevent weed establishment. A key component
to sustainable and effective weed management is minimizing weed
establishment throughout the management area with special attention
paid to eradicating weeds in and protecting high-quality areas -
that is, areas with high desired plant cover - and valued areas.
