Title

Litterfall in tabonuco (subtropical wet) forest in the Luquillo Experimental Forest, Puerto Rico (MRCE Litterfall data)
Summary

Short name: 

LUQMetadata111

Data set ID: 

111

Abstract: 

Treatments common to both sites are quarterly fertilization (macro- and micronutrients) and unmanipulated. At El Verde, a third set of plots was subject to a one time removal of litter and woody debris generated by Hurricane Hugo (September 1989).

Methodology

Methods: 

Plot layout at El Verde is a randomized block design (see map). Plots are 20x20 m square with 10x10 m inner measurement plots. Ten baskets 0.16 m 2 in area were randomly placed in each measurement plot.

The following treatments were applied to plots established within replicate blocks of tabonuco forest at El Verde, Puerto Rico within three weeks after a direct strike by Hurricane Hugo in September 1989: L (removal of all litter and woody debris); F (complete fertilization); and C (control). One control plot had a one-time accidental application of fertilizer between the two sample dates, so measurements were switched to a spare control plot in the same block in September – C(W). Treatments were applied to a 20x20 m area, and samples were taken from the core 10x10 m. There were 4 blocks established for this experiment, but one (Block III) was young and unlike the other three late-secondary forest blocks, so it was not included in analyses.

Samples were collected from each subplot and are reported by coordinates by D. Jean Lodge (DJL)  and by subplot numbers by others. DJL coded samples by Block (I, II and IV) and Plot (1-5) to compensate for dyslexia while others coded them as Block-Plot-Subplot numbers (e.g., 1-2-1 for Block II, Plot 1, Subplot 1).
