A keystone species is a species whose ecological role has a disproportionately large effect on the structure or function of an ecosystem.
Overview
What it means in practice
Keystone species should be read as a biodiversity and nature term. Its meaning depends on the ecosystem, geography, baseline, species or metric being used.
In practice, users should state the boundary, location, baseline and evidence source. That keeps keystone species specific enough for review without overstating certainty.
Why it matters
Keystone species matters because nature language can compress complex ecological conditions into a simple phrase. Clear wording helps readers understand whether the term describes status, pressure, response, target or measured outcome.
Common misconception
A common error is to use Keystone species without naming the ecosystem, species, geography or baseline. Those details are what make the term reviewable.
Review questions
What place, boundary or baseline gives the term meaning? What evidence supports it? What uncertainty or limitation would change the reader's interpretation?

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
