2. Beaver Island Association, “2019 Emerald Ash Borer Report to Community,” Beaver Island Forum, December 10, 2019.
   The Association referred residents to its 2019 EAB report on the organization website. The archived forum topic does not include the report text, so it establishes publication of a report referral but not its findings.

3. Beaver Island Association, “Forest Health Survey To Occur Next Week,” Beaver Island Forum, March 19, 2019.
   The Association announced that a multi-agency invasive-species team would survey island forests beginning March 25 for hemlock woolly adelgid and assess emerald ash borer. The notice establishes the planned survey and its stated targets, not the survey results, pest extent, treatment, or eradication.

4. Beaver Island Association, “March Update: Hemlock Wooly Adelgid (HWA) and Emerald Ash Borer (EAB),” Beaver Island Forum, April 11, 2019.
   The Association reported no evidence of HWA in the surveyed hemlock, one EAB beetle in 20 traps placed in 2018–2019, larvae at two of 21 reviewed sites, and plans to expand trapping and lure placement to Garden Island. These are Association-reported survey results; the archive does not hold the underlying field sheets or agency report, so the figures remain attributed rather than independently audited.

5. Pam Grassmick, “Emerald Ash Volunteers Needed,” Beaver Island Forum, July 18–22, 2019.
   A participant sought volunteers to drill a few dozen ash trunks so a certified arborist could inject treatment for EAB, corrected the work date to July 28, and later reported arranging instructions and equipment. This documents a planned local treatment effort, not the number of trees treated, treatment efficacy, or a complete infestation map.

6. Beaver Island Association, “Hemlock Woolly Adelgid Survey,” Beaver Island Forum, December 2, 2019.
   The Association said a Nature Conservancy grant would support a second HWA survey season, that prior state- and land-conservancy-held lands surveyed in March had been negative, and that the 2020 effort would seek permission to fill gaps on private lands. This is a first-party monitoring announcement and retrospective, not a complete 2019 survey report.
