The areas outlined in red are where I visited today.

Today’s work area.

Burn pile with today’s work area in the background.

Every stump had been carefully treated with herbicide.

Closer view of a treated stump. Herbicide has been applied liberally to the point some has run down the stem. It would be possible to cover more of the bark if needed to achieve a higher level of control.

Previous workday’s work area.

This is the northeastern most burn scar shown on the above map looking toward the east. Lots of stumps are visible in the background. The stumps are mostly from cut black cherry trees.

About 1/3 of the cherries that had been cut in previous years are sprouting. Some areas had few sprouting and other areas had many sprouting. The difference could be the amount of herbicide different applicators are applying.

These are cut sprouts on a previous cut black cherry tree. When woody species sprout, all the stems must be cut and treated with herbicide. This is much more work than if the tree had been killed by the initial herbicide application.

These are buckthorn grubs. Fire has burn them back to the ground. Fire will suppress them but will not kill them.

I located 60 cut buckthorn with a visible stump (excluding grubs) in an area where work occurred during a previous year. Of these 60 buckthorn stumps, half had been killed and half were sprouting. Applying herbicide to a length of the stem, proportional to the diameter of the stem, in addition to the cut surface would significantly improve the success of the herbicide application.

I did not find many Asian bush honeysuckle stumps. I only found three that were dead and two that were sprouting. These numbers are too small to be statistically significant. However, my experience has been, like common buckthorn, applying herbicide to a proportion of the stem of Asian bush honeysuckle, in addition to the cut, will increase the success of control.

Postscript: Rain occurred four days after the workday.
