• Plot Location
  • dataset_eml_methoddescription: Plots are randomly distributed within the study area and stratified by natural community type at a density of approximately 1 per 200ac

• Plot Design
  • dataset_eml_methoddescription: These are all nested plots. Plot center is marked with PVC pipe painted fluorescent orange. At the plot there are three main plots nested around the center stake. The overstory plot is 52.7’ in radius, the large sapling plot is 26.3’ in radius and the small sapling is 16.6’ in radius. To organize the data each plot is divided into 10, 36 degree sectors. At each plot the sectors are flagged out with a blue flag at 16.6’, an orange flag at 26.3’ and a pink flag at 52.7’. At each cardinal direction there are seedling plots located 26.3’ from plot center. At each of the seedling plots an orange painted PVC pipe is at plot center. From plot center a 100’ transect is established at a random azimuth and a PVC pipe is located at the end of the transect. Along this transect course woody material is measured from 0’-100’ and fine woody material is measured from 80’-100’.
