Tree regeneration after fire: Aspen removal experiment, soil moisture analysis 2002

This research was intended to address the general question of whether asexual stem regeneration of trembling aspen (Populus tremuloides Michx.) reduces rates of establishment and growth of potential invading conifer species during the initial years following fire. Interactions between aspen and conifers were studied under natural conditions in a burned aspen stand with a high potential for aspen re-sprouting. The study contributes to our understanding of whether competitive interactions between tree seedlings are likely to help maintain deciduous stands across disturbance cycles by reducing the potential for successful conifer establishment. Data are soil moisture from treatment and control plots measured from a single soil core from each plot sampled on 12 July 2002.本研究旨在解答一般性科学问题：火烧后初始数年，颤杨（trembling aspen, *Populus tremuloides* Michx.）的无性茎再生（asexual stem regeneration）是否会降低潜在入侵针叶树种（conifer species）的定植速率与生长表现。研究在一处具有高颤杨萌蘖潜力的火烧杨树林分中，于自然条件下开展杨属与针叶树的种间互作研究。本研究有助于深化对树木实生苗间竞争互作的认知，明确其是否可通过抑制针叶树成功定植的潜能，助力落叶林分（deciduous stands）在扰动周期（disturbance cycles）中得以维持。 本数据集涵盖处理样地与对照样地（treatment and control plots）的土壤湿度数据，相关数据于2002年7月12日采集，每个样地通过单根土芯（soil core）取样完成测定。
