Weed biodiversity and herbicide intensity as linked via a decision support system

open access: yesPest Management Science, Volume 81, Issue 10, Page 6667-6677, October 2025.
A high Shannon diversity of weed species leads to low herbicide intensity. The decision support system reduces herbicide intensity at low weed densities and thus supports biodiversity. Abstract BACKGROUND Extensive herbicide use is one reason for the declining biodiversity of arable weeds. This study aimed to investigate (i) whether herbicide decisions

Greater prairie‐chicken nest survival and changes in vegetation structure and composition with conservation grazing

open access: yesWildlife Society Bulletin, Volume 49, Issue 3, September 2025.
We studied how conservation grazing influenced vegetation composition and structure and greater prairie‐chicken nest survival in northwestern Minnesota. We observed effects of grazing on vegetation in the year of grazing, but these changes dissipated by August of the post‐grazing year.
