Tree Arena

About Tree Arena

Eight competitions on reviewed photographs of 1,036 tree species and 195 famous trees. Name a tree from the whole tree or a close-up of its leaves, needles, cones, flowers, fruit or bark; choose its Latin name; search for it by name; pick its native continent; estimate its mature height; match photographs to names; or pin a famous tree on the map.

Ten collections run from pines, firs and oaks to tropical trees, palms and Famous Trees. Play familiar trees, one collection or a balanced mix. Native ranges come from Kew’s World Checklist of Vascular Plants.

How to play

Goal

Recognize the world’s trees from their photographs and learn their names, Latin names, native continents, heights and the famous trees of the world.

How it ends

Finish ten questions or ten pairs, exhaust the sprint clock, or make one sprint mistake.

Record

Best score, highest Height Reserve or Map Pin reserve, or fastest Matching finish, with time and the player’s name.

1. Recognition Sprint: choose the pictured tree from eight names. You have 90 seconds and one wrong answer ends the run. Most correct answers wins; the time of the last one breaks ties. In Famous Trees the choices are other famous trees, mostly from the same country.
2. Leaves & Fruit: ten close-ups of a tree’s leaves, needles, cones, flowers, fruit or bark, each with eight names. A wrong answer scores nothing. Most correct answers wins, then the faster total time.
3. Latin Names: choose the scientific (Latin) name of the pictured tree from eight, mostly of related trees. Ten photographs; a wrong answer scores nothing. Most correct answers wins, then the faster total time.
4. Name Search: identify ten photographs. Type part of a common or scientific name or an alias and choose the exact tree from the alphabetical list. Correct answers rank first, then faster time.
5. Native Regions: choose one continent where the named tree grows natively. Any correct native continent earns a point; introduced, naturalised and planted trees do not count. Complete ten questions.
6. Height Reserve: estimate the mature height in metres or centimetres. You start with 1,000. A guess inside the reviewed range costs nothing; outside it you lose how many times too tall or short it was, on a logarithmic share of the 1–120 m range, at most 100 per guess. Ten estimates; highest reserve wins, then time.
7. Map Pin (Famous Trees): pin where the named tree stands, zooming as close as you like, then confirm. Within 25 km costs nothing; beyond, each started 20 km costs one point, at most 100. Ten trees; highest reserve wins, then time.
8. Matching: select a photograph, then its tree name, or drag one onto its partner. Match all ten pairs. Each wrong pair adds three seconds; fastest adjusted finish wins.

Tips

• Look at the close-up first Needles in bundles of two, three or five, the shape of a cone, or the lobes of a leaf separate trees that look alike from a distance.
• Read the genus Latin Names offers relatives, so the first word is often shared; the second word decides.
• Read the height scope Some ranges describe trees in cultivation, others wild trees. Planted trees often stay smaller than wild giants.

Good to know

Every photograph retains its creator, chosen licence, original title and source links. Creator credits appear beside the photograph; Full photo credit opens the complete attribution and sources. Opening full credits during a question, leaving the tab, restoring an unfinished run or a mid-run photo-loading interruption makes that attempt practice. Reviewed height ranges are source-specific references, not universal limits for every tree.
