Property Assessment:

How do we decide which control is best for you and your property?

ATV spraying

Property assessment:

weed species identification

Infestation densities

ecotype (range, forest, riparian)

aspect (N,S,E,W facing)

percent slope

native vegetation

tree density

 

Each job requires an assessment of the property.  The assessment entails a walk through looking at all species present (native and noxious).  The noxious weed infestations and densities will be documented and photographed.  Other considerations are slope or steepness of the property, ecotype (forest, grassland or riparian), and access to the project area.  Depending on these factors the project will be given a prescription.

 

Prescription:

WMA advocates integrated weed management, the idea that no one management tool is perfect but using a combination of management tools (Herbicide, Mechanical, Re-seeding and Biological controls) will provide the best control of noxious weeds.  Together we will decide the safest, most realistic options for your property.    

 

Multi-year approach:

Unfortunately, weeds are persistent and weed seeds are viable, in most cases, for up to 3 to 5 years.  This means although we’ve treated the living weeds (and lowered that year’s seed production), there are other seeds already on the ground waiting to germinate and   then have the opportunity to grow. 

In all herbicide applications we recommend considering treatment for 3 to 5 years depending on the site.  Only treating weeds for one year will reduce an infestation but never eradicate it.  Using multiple treatments over at least 3 years will show huge reductions in noxious weeds and the number of treatments needed in future years.
