Tree Growth and Regeneration in Quintana Roo (Mexico); Implication for Sustainable Forestry and Biodiversity

将在墨西哥金塔纳罗奥进行一个关于热带干燥森林可持续林业的跨学科项目。该项目将有助于实施和评估森林试点计划。关于树木生长和再生的数据将改进一种以计算机为基础的模型，该模型是为规划树木砍伐轮作而开发的。还将评价可持续林业对当地鸟类（生物多样性的一个重要组成部分）的影响。该项目有四个主要目标：(1)量化物种——重要商业树种的特定生长率，重点是土壤类型的影响和降雨的年际差异；(2)量化重要商业树种的自然更新，重点是种子生产和幼苗建立、存活和生长；(3)评估利用“细化”造林处理，通过去除邻近物种来促进具有商业价值的物种的生长；(4)评估选择性采伐对当地鸟类的丰度和物种组成的影响。

An interdisciplinary project on sustainable forestry in tropical dry forests in Quintana Roo (QR), Mexico will be conducted. The project will help to implement and evaluate the Plan Piloto Forestal. Data on tree growth and regeneration will improve a computer-based model that has been developed to plan tree cutting rotations. The impacts of sustainable forestry on the local avifauna, an important component of biodiversitiy, will also be evaluated. The project has four primary objectives: (1) quantify species- specific growth rates of commercially important tree species, with an emphasis on the influence of soil type and between-year differences in rainfall, (2) quantify natural regeneration of commercially important species with an emphasis on seed production and seedling establishment, survival, and growth, (3) evaluate the use of a silvicultural treatment "refinement" to enhance the growth of commercially important species by removal of their neighbors, and (4) evaluate the effects of selective logging on the abundance and species composition of the local avifauna.
