<p class="MsoNormal">I am trying to convince the land managers in my city (Greenbelt, MD) to start managing the invasive plants on some of their land. I am getting some pushback from a community group that says there’s proof that glyphosate will kill or damage
trees and soil biota. I’ve been looking for published papers that would support of refute their arguments, but have been unable to find much. (I don’t have access to JSTOR, BioOne, etc.)

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">They are citing the following documents: <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(1) Pennsylvania Extension Service: Tree roots absorb glyphosate; it has a much longer half-life than when it is in the soil. A single glyphosate application results in ,persistent stunted leaf growth.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(2) Michigan Extension Service: Herbicides that touch the bark of mature, healthy trees may be absorbed by the outer bark and negatively affect the adjacent vascular tissue.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">(3) Glyphosate interferes with the ability of tree roots to absorb manganese, zinc, iron, and boron from the soil; resulting in root rot, reduced cold hardiness, and reduced drought hardiness.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Does anyone have any resources that address these issues, or is there any known comprehensive document that reviews and summarizes independent research on the effects on glyphosate in forest ecosystems?<o:p></o:p></p>
