There is a set of natural and experimental burn plots on our property that now creates a hundred year chronosequence of plant succession after fire. There are 3 natural burns near our entrance drive that burned in 1901, 1911, and 1923. Our experimental burns date from 1936, 1948, 1954, 1980, and 1998. The control area was burned clear in 1907 (from ring counts). Each experimental burn plot is about a hectare in size (2.5-3 acres). They are located adjacent to each other in section 32. The 1980 burn has 4 20m x 20m permanent plots inside its boundaries. A 50m by 80m plot was established in the middle of the 1998 burn (and in the control area immediately to the west). Additional treatments in this plot include a deer exclosure fence and an aspen ramet removal area (see thesis by Laura White). The area in the NE corner was lightly burned in 1932 and did not follow a clearcut (under the supervision of L. J. Young, Professor of Silviculture). Robert Farmer Jr. established eight 66 ft2 plots - the Bob Farmer Plots - to quantify the effects of prescribed burns following clearcuts on Aspen trees. Six of these permanent plots are located within the 1936, 1948, and 1954 UMBS Burn Plots. Two are located in the 1952 clear cut, which was not burned. Measurements of the number of stems/acre of woody species in these plots are available for 1957, 1979 and 1998.
