Radial stem growth of stems in human-modified forests of Eastern Amazonia

This dataset includes measurements of stem radial growth in 20 plots (250 x 10 m each) in the Brazilian Amazon. Study plots were distributed across a gradient of forest disturbance, including: undisturbed primary forests , logged primary forests, logged-and-burned primary forests, and secondary forests. Data were collected from December 2014 until October 2018. In December 2015, during the El Niño-mediated drought, eight of our study plots were affected by understory fires.

Provenance & quality

We measured stem radial growth in 20 study plots (0.25ha) distributed along a gradient of forest disturbance in Eastern Amazonia: undisturbed primary forests (n = 5), logged primary forests (n = 5), logged-and-burned primary forests (n = 5), and secondary forests (n = 5). Forest disturbance classes were based on both an analysis of canopy disturbance in a chronosequence of satellite images (1988 to 2010) and on field assessments of fire scars, charcoal, and logging debris.

In each of the 20 plots, trees and palms were stratified in five DBH size classes: 10-19.99 cm, 20-29.99 cm, 30-39.99 cm, 40-49.99, and ≥50 cm. At least 50 dendrometer bands were installed in each plot and caution was taken to install dendrometers evenly amongst the size classes (10 in each size class). If a study plot did not have 10 trees in a given class, we distributed the remaining dendrometer bands evenly between the other DBH size classes. We also installed dendrometer bands in all lianas ≥10 cm DBH present in the study plots. Dendrometer bands were installed 10 cm above the DBH point of measure. Radial growth was measured every month.
