Fragments are the number of fragments sequenced per core, spp. richness is the total number of species found from sequencing the core, total root mass is the total mass in the core, % mass sampled is the percent of the total root mass sampled that was successfully sequenced. Root mass rank is the ranking of the species according to the mass of successfully sequenced roots, stem abundance rank is the rank of the species in terms of number of stems in the focal hectare, and basal area rank is the ranking of the species according to basal area.
