This two-year field study surveyed earthworm community characteristics on a chronosequence under afforested pine and hardwood lignite mine soils at the Beckville and Oak Hill lignite coal mines in east Texas. The following were used as indicators of earthworm community characteristics: reclamation type, forest cover type, age since reclamation and physical and chemical soil properties. The Beckville mine was sampled from February 2012 through March 2013; the Oak Hill mine was sampled from April 2013 through March 2014. The study was a 2x2x3 factorial design with reclamation type (mixed overburden vs. haul back), cover-type ((pine plantation (pp) and mixed pine …

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to …
