How we know this (2) Methods & honest limits

Leaf build Direct fact

We read each species’ measured specific leaf area (leaf area per unit dry weight) from the Global Spectrum dataset and band it: thin & fast (high SLA), medium, or thick & tough (low SLA). The global median is about 10 mm²/mg.

Honest limits: A species-mean from pooled measurements — individual plants vary with light and site. A broad strategy signal, not a precise per-plant figure.

Díaz, S. et al. (2022) The global spectrum of plant form and function: enhanced species-level trait dataset. Scientific Data 9:755.

Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.

Ecological value open data

3 / 5 Keystone

Keystone (host) value — caterpillar, specialist-bee & monarch hosting. A low number means “not a keystone host,” not “low value”: generalist flower-visitor value is shown separately below and in Bees & wildlife.

⚠ non-native — reduced keystone value

Deep dive

Caterpillar host · 3/5 — native butterfly & moth caterpillars that feed on this genus — the base of the food web (more caterpillars → more songbirds). Genus-level keystone count from Warren II 2026 (CC0; Tallamy host-use records), gap-filled by our GloBI derivation.

Deep dive — what these mean

Seed mass 1 mg — average weight of one seed. Bigger seeds are easier to hand-collect & direct-sow; dust-fine seeds need surface-sowing.

Leaf nitrogen 14.9 mg/g — measured leaf N. Higher = richer prunings for compost/mulch (a measured stand-in for "dynamic accumulator" claims).

Leaf build — how thick & tough the leaves are. Thin, lightweight leaves grow fast and crave light; thick, tough leaves last longer and shrug off shade, drought & grazing. (measured leaf area per dry weight, 6.4 mm²/mg)

Photosynthesis — the standard “C3” pathway most plants use, most active in cooler, moister, moderate-light conditions. (pathway C3)

Mycorrhiza ECM — the root–fungus partnership it forms (AM = most plants; ECM = most forest trees; ERM = heaths; NM = none). Trades sugars for water & nutrients via shared soil networks.

Measured traits from TRY + Werner et al. (N-fix), Fan et al. (roots) & FungalRoot — general guidance, not species-specific prescriptions.
