Description: A compilation of plant lists from all available sources since the 1950s represents the flora of the Penobscot Experimental Forest (PEF), Bradley, Maine. More than 300 taxa of vascular plants in 71 families and 186 genera are included. Approximately 85 percent of the taxa are native to Maine. Ten of 45 nonnative species are considered invasive. Infraspecific taxa have not necessarily been resolved, though 14 subspecies are included as they represent the species in the region. Two rare plants, Carex oronensis and Clematis occidentalis, have been documented. Omitted taxa overlap known species (e.g., "Salix sp." in which a single species is indicated), or are thought to be misidentifications. Sixty-two lichen and 49 bryophyte species are included provisionally. More species could be found in surveys for (1) ruderal plants in disturbed ground; (2) species found in the 1960s that are unknown today at the PEF; (3) expected, common species of spruce-fir that have not been documented; (4) graminoids, which seem underrepresented; and (5) species in riparian zones and wetlands. The plant checklist could be especially useful in documenting shifts in the flora that might be attributable to climate change. Nomenclature in a new flora of New England differs from the U.S. Department of Agriculture, Natural Resources Conservation Service database in significant ways; both sources should be considered in vegetation research in the PEF.
