description: 90-100 individual plants or plant patches are monitored at each site. Individuals of 3 dominant species at each site are targeted for monitoring during initial operations After which the pool of species monitored may expand up to 20 species. Sampling intervals at sites with clear seasonal patterns varies based on plant activitiy, ranging from 2-3x weekly during periods of rapid phenological transition to much less frequently during other times of year. Sites with less defined growing season are monitored year-round at weekly intervals. NEON employs status-based monitoring in which the phenological condition of an individual is reported any time that individual is observed. Depending on the growth form, an individual may have between 1 and 7 phenophases reported per observation event. Instrumentation:

title: Root biomass and chemistry, Megapit (DP1.10066.001)
title: RELEASE-2025

description: This data product contains the quality-controlled, native sampling resolution data from NEON's belowground plant biomass stock and chemistry measurements from Megapits. Soil samples were collected at 10 cm depth increments to the first 100 cm below the surface, then 20 cm depth increments thereafter, along three vertical profiles from a single temporary soil pit at a location expected to be representative of NEON sensor-based soil plots. This sampling activity is expected to occur once at each NEON terrestrial site. Root material is sorted, dried, weighed, and analyzed, then any excess root sample material is archived in the NEON Biorepository and are available on request. For additional details, see the user guide, protocols, and science design listed in the Documentation section below. Products resulting from this sampling include root biomass by size class and live/dead status, as well as root chemistry and stable isotope ratios. A summary table of external lab precision and accuracy is included in the expanded package.

Latency:
Data were collected once, at the establishment of each site. Data were published within one year of collection, and future collections at existing sites are not expected.
description: Each site is sampled a single time. At each site, a soil Megapit is dug in the dominant soil type to a maximum depth of 2 m. On the exposed face of the soil pit, a tape measure visually divides the soil profile into 10 cm depth increments. Each soil pit has three vertically-oriented sampling profiles, roughly corresponding to the left, center, and right of the pit sampling face. These profiles are referred to as profile number 1, 2 and 3, respectively. From each profile, a block of soil is removed from each 10 cm depth increment, starting from the surface down to 100 cm. Once a depth of 100 cm is reached, the each profile is divided into 20 cm depth increments. By the end of sampling, up to 45 soil samples are collected, 15 per profile. Roots are sieved and then divided into four categories distinguishing between status (alive or dead) and size (> 2mm and < 2 mm, unless otherwise noted). Once roots are weighed and dried, they are sent to an external laboratory for analysis of carbon and nitrogen concentrations and stable isotopes. Any remaining root material is held in the NEON Biorepository and available upon request. Instrumentation:

title: Root biomass and chemistry, periodic (DP1.10067.001)
title: RELEASE-2025

description: This data product contains the quality-controlled, native sampling resolution data from NEON's belowground biomass protocol. These data enable estimation of the amount of belowground plant biomass <= 10 mm diameter within the area surrounding the NEON eddy covariance tower. At many sites this will also be the dominant vegetation type(s). Samples are collected once every five years. Whenever possible, NEON uses a 3-inch outside diameter (6.65 cm inside diameter) soil corer for belowground biomass sampling, with samples cored to 30 cm depth in order to be consistent with the sampling depth used for soil biogeochemistry and microbe sampling. All roots are sorted into three size category bins: <1 mm, 1-2 mm, and 2-10 mm. After sorting, root material is dried, weighed, and analyzed, then any excess root material is archived in the NEON Biorepository and available upon request. For additional details, see the user guide, protocols, and science design listed in the Documentation section below. Products resulting from this sampling include root biomass by size class as well as root chemistry and stable isotope ratios. A summary table of analytical lab precision and accuracy is included in the expanded package.

description: Each site is sampled every five years. At each terrestrial NEON site, roots are sampled from base plots (20-30) within the tower airshed (Tower plots). In each Tower plot, one or two clip cells (depending on plot size) are randomly chosen out of the pre-determined clip cell locations for root coring. The same clip cells are also used for annual aboveground Herbaceous Biomass sampling. In 20m x 20m Tower plots, two soil cores are sampled from one clip cell per bout. In 40m x 40m Tower plots soil core sampling occurs in two (out of four) randomly assigned 20m x 20m subplots, and two soil cores are sampled from one clip cell per subplot per bout. A root core is taken to 30 cm maximum depth from both the northern and southern end of the clip cell. Biomass per size category is pooled by clip strip prior to chemistry analyses, and only live or unsorted biomass is analyzed. Carbon and nitrogen concentrations and stable isotopes are measured, but other analyses are possible by requesting access to remaining root material from the NEON Biorepository. Instrumentation:

title: Small mammal box trapping (DP1.10072.001)
title: RELEASE-2025

description: This data product contains the quality-controlled, native sampling resolution data from NEON's small mammal sampling protocol. Small mammal abundance and diversity are sampled at regular intervals by NEON field technicians at core and gradient sites. Here small mammals are defined based on a combination of behavioral, dietary, and size constraints, as the NEON design is limited to species sampled by box traps. This definition includes any mammal that is (1) nonvolant; (2) nocturnally active; (3) forages predominantly aboveground; and (4) is greater than 5 grams but less than approximately 500-600 g. In North America, this includes cricetids, heteromyids, small sciurids, and introduced murids. It does not include shrews, large squirrels, rabbits, or weasels, despite the fact that individuals of these species may be incidentally captured. Products resulting from this sampling include the species identification and unique identifier for each individual captured, as well as a suite of standard size measurements and reproductive condition data. Sample identifiers for any blood, ear, hair, whisker, fecal, and/or voucher samples collected are also provided. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.

description: Small mammal sampling is based on the lunar calendar, with timing of sampling constrained to occur within 10 days before or after the new moon. Sites are typically, sampled 4 times per year, when season-length allows. Small mammals are sampled using box traps (models LFA, XLK, H.B. Sherman Traps, Inc., Tallahassee, FL, USA). Box traps are arrayed in four to six (depending on the size of the site) 10 x 10 grids with 10m spacing between traps at all sites. Small mammal trapping bouts are comprised of one or three nights of trapping, depending on whether a grid is designated for pathogen sample collection (3 nights) or not (1 night). Instrumentation:

title: Small mammal sequences DNA barcode (DP1.10076.001)
title: RELEASE-2025

description: This data product contains the quality-controlled laboratory metadata and QA results for NEON's cytochrome oxidase I (COI) barcoding of small mammal sequences. The DNA barcoding procedure involves the non-distructive collection of tissue from live specimens in the field, extracting and sequencing DNA from the tissue, and matching that sequence data to sequences from previously identified voucher specimens. DNA analysis serves a number of purposes, including verification of taxonomy of specimens that do not receive expert identification, clarification of the taxonomy of rare or cryptic species, and characterization of diversity using molecular markers. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage. These queries will also provide links to the actual sequence data, which are publicly available on the [Barcode of Life Data System](http://www.boldsystems.org/) (BOLD) website. The sequence data can be obtained by following the links from the NEON data portal, or by directly querying NEON data sets on the BOLD server. From the NEON portal, the link "BOLD Project: Small Mammal sequences DNA barcode" redirects to a page on the BOLD public data portal for the queried data. This is a dynamic link and will automatically update based on the user query.

description: Soil sampling occurs annually at a minimum of one site per domain and once (sites with short growing seasons) to three times per year (sites with longer growing seasons), with collections occurring at every sampled site during the historic peak in vegetation greenness. Three pre-determined, randomly assigned locations are selected for each sampling event within each of 10 plots distributed throughout a site; sampling locations within a plot are not re-sampled. Soil samples are collected to a maximum depth of 30 cm, with organic and mineral soils sampled separately. The same samples are used for measurement of soil physical and chemical properties to maintain temporal and spatial connectivity. Subsamples of homogenized soil (rocks, roots and organic debris removed) from each of the 3 sampling locations are stored in sterile containers, frozen on dry ice in the field and shipped to an analytical facility for DNA sequence analysis using primer sets targeting the small subunit of the ribosomal RNA gene. Sequence data undergo QAQC and are processed bioinformatically using an in-house pipeline to identify unique sequence variants in the data and to taxonomically identify each sequence variant.
