Abstract:

This data publication contains all available data collected from 1952 through 2023 at the Penobscot Experimental Forest in Bradley and Eddington, ME, under the study plan: FS-NRS-07-08-01 "Study Plan: Silvicultural effects on composition, structure and growth of northern conifers in the Acadian Forest Region: Revision of the Compartment Management Study on the Penobscot Experimental Forest". This third edition comprising data previously published and data collected since the publication of the second edition in 2015. Data were collected on a series of permanent sample plots distributed across management units receiving various silvicultural treatments. Plot data are available in eight separate data sets. Overstory tree and sapling data include tree species, condition (e.g., merchantability status and cause of mortality), and diameter at breast height of living and dead trees, 1952 to 2023. Regeneration data include tree seedling species, presence, and count by height class, 1964 to 2023. Tree location data include the distance and azimuth from plot center of a subsample of trees, 2003 to 2023. Height and crown radius data include total height, height to crown base, and crown radius measurements for a subsample of live trees, 2003 to 2020 (heights) and 2003 to 2017 (radii). Understory vegetation and substrate data include percent cover by substrate and vegetation categories, 2003 to 2023. Standing deadwood data include heights and bark condition of standing snags, 2013 to 2020. Permanent sample plot location data include geospatial coordinates for permanent sample plots, 2018 and 2020. Depth to water table data include minimum, maximum, and average water table depths at three drainage thresholds at each plot location, 2023. Future inventories are planned for this study indefinitely.
