Terrestrial Litterfall Collection (NEON-TLFC)

Litterfall subsample for archive (NEON sample class: ltr_chemistrySubsampling_in.archiveSampleID). Litterfall is defined as shed leaves and needles, reproductive parts (i.e. flowers, fruits, cones, seeds, etc.), and fine woody debris with butt-end diameter < 2 cm. To measure litterfall and fine woody debris, NEON employs two types of sampling units: 1) square, elevated, mesh litter traps; and 2) rectangular, ground “traps”. Elevated litter traps are designed to be large enough that the average size of abundant foliage and fine woody debris elements are easily intercepted by the trap. Ground traps are intended to intercept particularly large foliage elements that will not fit in elevated traps (e.g. palm fronds), and fine woody debris pieces that are too long to be sampled in elevated traps including small diameter branches. Both elevated and ground traps are established in Tower Plots. The timing and frequency of sampling for elevated traps depends on the dominate vegetation type at the site. Ground traps are sampled once annually (± 2 weeks) at Tower Plots. Subsamples for archive are oven-dried at 65 degrees Celsius for at least 48 hours then ground in a Wiley mill to 20 mesh size (sieve opening size = 0.0331 in) then transferred to a 20 mL HDPE scintillation vial. Archived samples are stored at room temperature. See TOS Protocol and Procedure: Litterfall and Fine Woody Debris (https://data.neonscience.org/documents) for more information about this sample class. NEON datasets (https://data.neonscience.org/home) associated with this sample class include Litter Chemical Properties (carbon, nitrogen, and lignin concentrations), Litterfall and Fine Woody Debris Sampling, and Litter Stable Isotopes.
