The Holt Research Forest Technicians have officially completed the latest 100% Complete Timber Inventory! This major feat was only possible thanks to the tireless efforts of several research technicians over the years who have dedicated their summers to collecting long-term ecological monitoring data with us. 100% Complete Timber Inventories are conducted by identifying, measuring, and recording the status of every single overstory tree within the study grid, which is just un

The Holt Research Forest (HRF) is an oak-pine forest dominated by eastern white pine and northern red oak. In fact, just before the second group-selection harvest in 2020, white pine accounted for over 45% of the forest by basal area, whereas northern red oak came in second at just over 20%. Although not nearly as prevalent as white pine and red oak, white oak is also a species of interest at HRF and makes up just under 5% of the forest. Figure 1. Pre-harvest overstory compos

Community members gathered to celebrate the culmination of the Maine TREE Foundation’s 2026 field season. The celebration highlighted the hard work, field discoveries, and independent projects completed by this year’s vibrant cohort of interns, research technicians, and fellows. Since June, these individuals have engaged in independent projects while managing their role responsibilities. “Each summer, I have the distinct privilege of welcoming some of the most talented and am

2026 Forestry Immersion Program participants and educators. The Forestry Immersion Program, a six-week summer forestry experience for high school students, hosted a celebration as students welcomed family, friends, and supporters to see what they accomplished throughout the program. Guests witnessed the many skills students developed through hands-on learning as they led demonstrations on chainsaw safety, tree identification, whittling, and camp life. These activities reflect

Maine TREE kicked off its summer field season at Holt Research Forest (HRF) this past Thursday with a welcome event for its largest cohort of summer interns, fellows, work study students, and research technicians to date. In addition to the general responsibilities of their positions, each will complete an independent project, ranging from multimedia content development to invasive plant management to fungal fruiting-body survey. These early-career professionals bring a diver

Our S-l0 transects are l0m-wide strips that run the length of the "E" and "I" blocks (Fig. 1). On the S-10s, researchers have collected sapling and crown measurement data. Mapping and measuring tree heights and crowns on the S-10s allows us to better understand tree growth, including the role of regeneration trees within the system, particularly in response to timber harvests.

Following the success of previous pilot initiatives, the Brewer School Department and the Maine TREE Foundation are proud to announce the return of the Forestry Immersion Program for the summer of 2026. This unique educational partnership is made possible by a grant from the Northern Border Regional Commission (NBRC), which aims to strengthen the region's forest economy and workforce pipeline.
