<p>this is my only concern about the application of roundup, I'm nervous about killing off oaks cherries and maples in the surrounding forest through the root systems. in your experience have you seen any sort of kill off of these trees from cut stump with roundup?</p>
<p><strong>Response</strong></p>
<p>In the research that I did, and that of the USFS there was never (0%) any evidence of movement of glyphosate (the active ingredient in Roundup) to species other than beech. We monitored adjacent upper canopy trees for 12 months following treatment and there were no changes in the health rating assigned to the crown of adjacent trees. Also, glyphosate binds to soil organic matter and is non-active and non-mobile in the soil...if you spill some there shouldn't be any problems (but of course try not to spill). Glyphosate is the most mobile of herbicides within the beech root system, but is non-mobile to other species. </p>

<p>You will want to use at least 25% active ingredient of glyphosate and as soon after cutting the beech as possible. The glyphosate will move to the tallest root suckers you leave, so if there are numerous 3" to 5" diameter suckers those will preferentially take the glyphosate and allow less to move to the smaller beech whips. So, the number of saplings in the different diameter classes matters. The moral of this story is that if you have large saplings, try to cut and treat (and treat) as many as possible to allow for sufficient movement of glyphosate to the smaller stems.</p>
<p>Here's a picture of a stand at the Arnot Forest that we will need to devise a "beech plan" for. Likely a combination of basal drill-n-fill just prior to harvest, with post harvest foliar and Garlon 4/triclopyr basal bark. Picture by Brett Chedzoy</p>
