The Forest's Long Term Ecological Research (LTER) program, established in 1988 and funded by the National Science Foundation, provides a framework for much of this activity.Forest Research at Harvard ForestBooseEmerybrowsingforest healthcontinuous forest inventory forest regenerationresearchHurricane Recovery Plots at Harvard Forest since 19371937-01-01The New England hurricane of 1938, by destroying many acres of mature and semi-mature forests, initiated new forest associations over a large area. Permanent plots were established across the Harvard Forest in severely damaged stands (many of which were logged subsequent to the hurricane) to assess forest succession. Most of the plots involved successions following the blowdown of white pine on glacial till or outwash soils. From 1940 to 1948, and in 1978 and 1991, tree density and presence or absence of herb and shrub species were tallied. Pioneer species regenerating from seed and advance regeneration of longer-lived species quickly established at the sites; hemlock was the only species successfully regenerating after year 10, and most tree species were present within 2-4 years of the hurricane. By 1978, pioneer species such as gray birch and pin cherry declined or disappeared and red maple, white pine, paper birch and red oak dominated the plots. By 1991, most understory species present before the hurricane had returned, although there was a small group of understory species that apparently were more sensitive to disturbance and did not recover.To observe the succession of forest stands that were destroyed by a hurricane in 1938 and then, for the most part, logged after the hurricane.VMC.1387.2866mySQLFoster D, Spurr S. 2009.
