Burning
Starting in 1989, two sections in each macroplot were burned in fields B and C. Each macroplot is divided into 5 sections. In each macroplot, the center section and 1 section on either the east or west side of it were burned. Starting in 1992, two sections in each macroplot were burned in field A as well.
