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 …
