Each species' share of the stand's basal area (the summed cross-sectional area of all its stems), the standard measure of how much a species occupies a stand, weighting big plants over small. Computed at breast height for trees, at the base for shrubs.
Live, species-identified stems with a measured diameter.
Written from this site's live data, the same numbers the rest of the app uses.
Every bundled NEON site ranked by species richness . The gold bar is the site you're viewing. Answers the question no site-local number can: is this a lot?
Richness here is the count of identified woody species in the site's bundle.
How is this stand built?
The size-class distribution, basal area and stem density per hectare, and the height profile, the structural fingerprint of the stand.
Live woody plants binned by stem diameter (cm). In forests that's tree DBH ā„ 10 cm ; in deserts/shrublands it's basal stem diameter (shrubs are too short for a breast-height measurement).
A descending āreverse-Jā (many small, few large) is the signature of a regenerating, uneven-aged stand. For forests, smaller saplings are tallied in separate nested subplots over a smaller area, so they're excluded here to avoid a sampling artifact.
On forest stands the dashed line is the idealized reverse-J decline (a negative-exponential / de Liocourt trend) fit to this stand. Bars sitting below it in the small classes flag a possible recruitment gap , too few young trees coming up.
The distribution of live-plant heights (m). Plants measured for diameter but not height aren't shown here.
Basal area (mĀ²/ha) and stem density (stems/ha), scaled by each plot's sampled tree area then averaged, so a bigger plot doesn't dominate. Quadratic mean diameter (QMD) is the diameter of the tree of average basal area.
These are stand-level indices from the sampled plots, not a wall-to-wall inventory.
How do the plants change?
Diameter growth between remeasurements, the fastest growers, and the live/standing-dead breakdown. NEON remeasures most plots every ~5 years, so growth is per-year between visits.
Annualised stem-diameter increment (cm/yr) for plants measured at two or more visits, one rate per plant, DBH for trees, basal diameter for shrubs. Plants are remeasured every few years, so this is Īdiameter Ć· years between visits.
Some plants show a decrease , usually real (bark sloughing, drought, a changed measurement height), not an error; those are kept and flagged on the plant card.
Two different things, shown together. The annual rate (compound, Sheil & May) is 1 ā (1 ā deaths/Nā)^(1/years) over the tracked cohort, the forestry standard, comparable across stands.
The pie is a snapshot : each tagged individual at its most recent visit, Live if any stem is live, not a rate.
āLost track / removedā (lost tag, removed, no-longer-qualifies) is a data state, kept separate from biological Dead so neither the rate nor the pie misreads it as mortality.
Each dot is a remeasured plant: its current diameter (x) against its annual growth (y), coloured by species, the structural twin of the small-mammal Size Lab.
A dashed trend line is drawn only when the sizeāgrowth relationship is real (n ā„ 12, |Spearman r| ā„ 0.15, p < 0.05); otherwise it's an honest scatter with a āno clear trendā note, no fabricated line.
Plants ranked by annualised diameter growth (ā„2 visits spanning ā„1 year), DBH for trees and basal diameter for shrubs. Implausible jumps (>5 cm/yr) are excluded as likely measurement issues, not champions.

The four corners are the size-shape extremes (big-tall, thin-tall, big-short, small-short); the exact labels adapt to forests vs shrublands. The gold diamond is the plant you're viewing.
The record-holders
The biggest, tallest, fastest-growing, and longest-tracked plants at this site. Tap any one to open its full career.
Live plants ranked by the chosen metric. Fastest grower is the annualised diameter increment for remeasured plants (implausible >5 cm/yr jumps and changed measurement heights excluded). Longest career counts distinct measurement visits.

Search the network
Look across every bundled NEON site at once, with no loading and no download. Find which sites a woody species grows at, or list the sites that pass a size threshold, then jump straight into any one.
Pick any woody species recorded at a bundled site. The table lists every site where it grows, with that species' live basal area (mĀ²/ha) and live stem count at the site, and the years it was measured.
Basal area is area-standardized within each site (summed stem cross-section over the sampled plot area), an honest within-site amount, not an absolute cross-site ranking. Forest sites are sized by DBH and shrubland sites by basal stem diameter, which are different measurements, so the structure column is shown.
List the sites whose stand passes a size threshold. Basal area (mĀ²/ha) is the live stand's cross-sectional stocking; biggest stem and tallest plant are the site's record sizes.
Forest sites (sized by DBH at breast height) and shrubland sites (sized by basal stem diameter at the base) measure size differently, so these aren't a single absolute ranking; the structure column tells you which paradigm each row is. Filter to one structure type to compare like with like.
