Baseline Plant Abundances on Garlic Mustard Experiment Plots at Harvard Forest 2013

This is a five year project that investigates the reassembly of soil fungi and native plants in forests affected by biological invasion. The experiment brings together regional land managers to create comparative eradications of garlic mustard at nine distinct sites along a natural climate and nitrogen deposition gradient in New England. This dataset represents baseline plant abundances from 2013 at nine study plots in Harvard Forest. Species richness, Shannon diversity, and Pielou’s evenness were not different between invaded and non-invaded plots at Harvard Forest.本项目为一项为期五年的研究课题，旨在探究受生物入侵干扰的森林生态系统中土壤真菌与本土植物的群落重建过程。本实验联合区域土地管理者，在新英格兰地区沿自然气候与氮沉降梯度布设的九个独立样地中，开展北美蒜芥（garlic mustard）的对照清除实验。本数据集涵盖2013年哈佛森林（Harvard Forest）九个研究样地的基线植物丰度数据。研究结果表明，哈佛森林内的入侵样地与未入侵样地在物种丰富度、香农多样性指数（Shannon diversity）及皮卢均匀度指数（Pielou’s evenness）上均无显著差异。
