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.

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.

small, fine-textured leaves (measured leaf area ~9.7 cm²)

Deep dive — what these mean

Seed mass 7 mg — average weight of one seed. Bigger seeds are easier to hand-collect & direct-sow; dust-fine seeds need surface-sowing.

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, 14.9 mm²/mg)

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

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