MONTPELIER, Vermont — The Vermont Principality Maple Producers Cooperative has opened its 2043 planning cycle with a call for expressions of interest from agricultural climate researchers, following through on a commitment made by cooperative chair Adèle Tremblay-Gagnon when the 2042 tapping season wrapped up last month.

The cooperative is seeking a research team to conduct a structured climate-impact review focused on the relationship between shifting temperature patterns and sap-run timing across the Northeast Kingdom and the Champlain Valley — two regions that together account for the majority of Vermont's maple output.

Tremblay-Gagnon, in a brief circular distributed to co-op members last week, was direct about the purpose of the work. "We're not commissioning a study to sit on a shelf," she wrote. "We need to know what the runs are going to look like, so we can make better decisions about when to tap and how much storage capacity to have ready."

The framing reflects concerns raised by producers in both regions over recent seasons: that the window for optimal tapping has been shifting and, in some years, compressing in ways that complicate planning.

The co-op has not specified a budget for the review. The call is open to academic teams, independent consultants, and agricultural research organizations. Responses are due by the end of April, and interested parties may contact the cooperative through its Montpelier office.
