Title

Litterfall production in human-modified forests of Eastern Amazonia

Abstract

This dataset includes measurements of litter 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 January 2015 until October 2018. In December 2015, during the El Niño-mediated drought, eight of our study plots were affected by understory fires.

Lineage

We sampled litter 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. Six litterfall traps (50 x 50 cm; 0.25 m2) were installed in each plot, spaced 50 m apart. Traps were placed 1.20 m above the ground. Trap contents at each site were collected every two weeks. All samples were taken to the field lab and separated into six parts – leaves, flowers, fruits, seeds, wood, and rest (i.e. non-identifiable parts). Samples were then oven-dried at 80oC for 3 days before being and weighed to the nearest 0.01 g.
