Resistance of herbaceous covers against tree establishment

This repository contains the data used for the manuscript entitled: \"Resistance against tree encroachment is driven by richness and identity of herbaceous resident species\". This investigates the potential of herbaceous plant covers in inhibiting tree encroachment, focusing on the resistance against two undesirable native tree species, Acer rubrum and Betula populifolia, over an extended period. Both species frequently establish in unmanaged grasslands and old fields. They also frequently encroach under electrical powerline rights-of-way in northeastern North America, where they are considered a nuisance requiring frequent control operation.

本数据集仓库收录了题为《草本定居物种的丰富度与物种组成驱动树木侵占抗性》的学术手稿所用的全部数据。该研究旨在探究草本植被覆盖抑制树木侵占的潜力，重点考察长期观测周期内本土两种有害树种——红花槭（Acer rubrum）与美洲灰桦（Betula populifolia）的抗侵占能力。这两种树种常于无人管理的草原及弃耕农田中自然定植，同时也常会在北美东北部的电力线路通行区域内侵占生长，在该区域内此类树木被视为有害物种，需开展频繁的防控作业。
