2022 Agua Salud Soil CO2 Fluxes - Raw Data

Raw data on soil CO2 fluxes, forest floor mass, soil moisture, soil temperature and soil organic carbon collected from 20 forest sites in a chronosequence in Agua Salud, Panama between September 2 2022 and December 2 2022. Data was collected in order to determine how soil CO2 fluxes and relevant drivers change as tropical moist forest naturally regenerates on former pasture lands. Measurements were taken in pasture plots and three secondary forest age classes including 7 years, 24-32 years, and 80+ years after forest establishment. 10 samples for soil CO2 flux, forest floor mass, soil temperature and soil moisture were collected for each site, split between upslope and downslope transects (200 measurements total), while 5 samples for soil organic C were collected per site (100 measurements total). The data shows a significant (nearly two-fold) decrease in soil CO2 fluxes between the pasture plots and forest plots. The table shows site identification, forest age, intermediate values for relevant calculations and final values for CO2 flux, forest floor mass, soil organic C, soil temperature and soil moisture.

本数据集收集了来自巴拿马阿瓜萨卢德地区20个森林样地，在2022年9月2日至12月2日期间所测得的土壤CO2通量、森林地表生物量、土壤湿度、土壤温度以及土壤有机碳的原始数据。数据收集旨在探究热带湿润森林在昔日牧场的自然恢复过程中，土壤CO2通量及其相关驱动因素的变化情况。测量在牧地样地和三个次生林龄级（包括建立森林后的7年、24-32年及80年以上）进行。每个样地收集了土壤CO2通量、森林地表生物量、土壤温度和土壤湿度各10个样本，分属上游和下游横断面（总计200个测量值），同时每个样地还收集了5个土壤有机碳样本（总计100个测量值）。数据显示，在牧地样地和森林样地之间，土壤CO2通量存在显著（近两倍）的下降。表格展示了样地标识、森林年龄、相关计算的中值以及CO2通量、森林地表生物量、土壤有机碳、土壤温度和土壤湿度的最终值。
