UMBS Burn Plots

UMBS Burn Plots

Site Overview: 

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.

Tree Ring and Stem Dissection
Deer Exclosure Plot (1995) Vegetation Survey from 1997 A deer exclosure plot was established in 1995. The plot is fenced in to prevent deer browsing of vegetation. The plot was surveyed for overstory level woody vegetation, ground level woody vegetation, and ground level herbaceous vegetation.
Deer Exclosure Plot (1997) Vegetation Survey from 1997-1999 Two deer exclosure plots were established in 1997 to prevent deer browsing of vegetation. The plots were surveyed for ground level (g) and overstory (o) woody and herbaceous vegetation.
Small mammal census data This dataset is an ongoing census of small mammals at 3 sites at UMBS: Colonial Point, forest adjacent to the Burn Plots, and Reeseā€™s swamp. The census is based on live-trapping carried out each year since 1989 in early May (before the first litters of the year are born) and mid September (after...
