Tree-ring–based diameter growth data for Rhizophora mangle in the Colombian Caribbean

Cispatá Bay, located in the Colombian Caribbean, hosts the country’s only mangrove under a regulated sustainable use model. Yet, current management guidelines rely on generalized silvicultural criteria, which do not reflect species-specific growth dynamics, potentially compromising sustainability. This study aims to improve sustainable forest management in Cispatá Bay by developing species-specific growth models for Rhizophora mangle, a dominant and heavily harvested species. We used tree-ring data from 26 dead individuals to evaluate diameter growth, and applied nonlinear mixed- effects modeling, accounting for autocorrelation and growth eccentricity. The resulting models yielded biologically meaningful ontogenetic traits and silvicultural parameters, including a maximum mean diameter, a weighted average growth rate, a lifespan, and a halflife.西斯帕塔湾（Cispatá Bay）坐落于哥伦比亚加勒比海海域，拥有该国唯一一处按照规范化可持续利用模式管理的红树林。然而当前的管理导则仅依赖通用营林标准，未能体现物种特异性生长动态，或对可持续性造成潜在威胁。本研究旨在通过为优势且被高强度采伐的美洲红树（Rhizophora mangle）构建物种特异性生长模型，以优化西斯帕塔湾的森林可持续管理工作。我们采集了26株枯立木的树木年轮数据以评估其直径生长量，并采用纳入自相关与偏心生长效应的非线性混合效应模型开展分析。所构建的模型可输出具备明确生物学意义的个体发育性状与营林参数，包括最大平均胸径、加权平均生长速率、寿命及生长半衰期。
