Description

The dataset provides location, vegetation, and soil attributes from 288 plots. Location is described in latitude and longitude. To describe overstory and understory structure, we utilized total basal area (> 2.54 cm dbh) of trees and understory species cover (%) and richness. To describe soil and forest floor attributes, we used forest floor C and N concentrations and thickness; and mineral soil C and N concentrations, and pH for 0-20 cm mineral soil depth for each plot. 

Data was collected from U.S. Forest Inventory Analysis Program (USDA, Forest Service; https://apps.fs.usda.gov/fia/datamart/), and analyzed and presented in “Jo, I., Potter, K., Domke, G., and Fei, S. (2017) Dominant forest tree mycorrhizal type mediates understory plant invasions. Ecology Letters, in press.”
