Observation Narrative	This fen at Grayson Glades NAP has been heavily disturbed by past land use but maintains populations of several state-rare plant species and extraordinary fine-scale species richness. Nested subquadrats were not established because of very tight species packing, and some species may have been overlooked. Diversity of this plot is higher than that observed at Big Spring Bog NAP, when woody species in the latter are controlled for. Although vegetative cover is high and dense, and trampling compacts the soil down to the water table, surficial cover of water may have been underestimated. Solidago uliginosa occurs just outside the plot.
