Tree size and biomass measurements for 27 species in Mexican secondary tropical dry forests

We present a dataset on tree size and aboveground biomass for 303 trees representing 27 tropical dry forest species harvested along a chronosequence of secondary forests on the coast of Jalisco, Mexico. These data were previously used by Bojórquez et al. (2020; https://doi.org/10.1016/j.foreco.2020.118384) to develop and validate allometric models for estimating aboveground biomass in secondary tropical dry forests. We believe this dataset provides valuable information for constructing allometric models that can be applied to similar forests at broader spatial scales, including regional, national, and pantropical contexts.

本数据集涵盖沿墨西哥哈利斯科州沿岸次生林演替时间序列采伐获得的303株树木的树体尺寸与地上生物量数据，这些树木分属27种热带干旱森林树种。Bojórquez 等人（2020年，DOI：10.1016/j.foreco.2020.118384）曾利用该数据集构建并验证了用于估算热带干旱次生林地上生物量的异速生长模型（allometric model）。我们认为，本数据集可为构建适用于区域、国家乃至泛热带等更广空间尺度同类森林的异速生长模型提供极具价值的参考信息。
