I think things will be okay.

A good organic mulching and composting program will create a resilient microherd in only a few weeks, and plants will thrive. A strong microherd also breaks down chemical residues, and the more robust it is, the faster it breaks down toxins in the environment, and the more capable it is at preventing toxic effects from drift.
The good news is that things look better this year than they have in the past.
Anyway, I will continue adding mulch as I find it... And make a bigger circle with it too.

Not knowing where on Vancouver Is. you are located, I don't know which of the two major ecoregions pertain to you (actually, they both may, due to micro-climates), but here are two links to the general descriptions.
