Brief Summary of Restoration Efforts

Restoration Goal. Mesic, bur oak savanna.
Field Operations. Restoration in this area began in the summer of 2000 with canopy thinning. American elm, black cherry, slippery elm, and shagbark hickory were removed. Brush and logs were piled and burned. Dead trees in the southeast portion of the area were cut and piled in the spring of 2003. Multiflora rose and burdock have been sprayed annually. Prescribed burns have been conducted annually in late March beginning in 2002.

Monitoring

Five permanent 90-meter ground layer vegetation transects were established through the area in November 2000. Light monitoring at intervals along each transect was initiated in September 2003.

Herbaceous cover

Vegetation sampling method: A 0.25-m2 quadrat frame was placed adjacent to a tape measure at 5-meter intervals along each 90-meter transect. Percent aerial covers of all species rooted within the frame were recorded. Cover values were assigned using the following classes: (1) 1-20% (2) 21-40% (3) 41-60% (4) 61-80% (5) 81-100%. Some species were only identifiable to genus and a few only to family.

Sampling dates: November 2000, August 2002, September/October 2003.

Light availability

Light sampling method: A LiCor photometer was held 1-m above each quadrat to measure µmoles of photons/m2/second and fifteen second averages were recorded. Full sun readings were recorded prior to and after all measurements within a transect.

Sampling dates: September/October 2003.
