Sycamore is not native to Britain or Ireland but has been here for centuries and is now one of the commonest trees, valued as a tough street, shelterbelt and coastal tree and as a timber and bee tree. Conservationists debate it: it self-seeds into native woodland and is removed from many nature reserves, yet it also supports aphids, pollinators and nesting birds.","care":"Needs no special care once established; water the first summer. Prune in late summer to avoid bleeding. Sooty bark disease (Cryptostroma corticale) can kill stressed trees after hot summers and its spores can cause lung problems; horse chestnut scale and aphid honeydew are cosmetic. Expect prolific seedlings.","benefits":["shade","windbreak","salt_tolerant","pollinators","fast_canopy","long_lived"],"uses":["street_tree","windbreak","timber","parks","yard_shade"],"cautions":["invasive_elsewhere","heavy_litter","large_roots"],"image_url":"https://upload.wikimedia.org/wikipedia/commons/c/cd/Acer_pseudoplatanus_005.jpg","image_credit":"Wikimedia Commons, file Acer_pseudoplatanus_005.jpg (see file page for author and licence)","sources":["https://www.woodlandtrust.org.uk/trees-woods-and-wildlife/british-trees/a-z-of-british-trees/sycamore/","https://nonnativespecies.org/non-native-species/information-portal/view/25","https://www.gbif.org/species/3189870","https://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=275368","https://plants.ces.ncsu.edu/plants/acer-pseudoplatanus/"],"data_note":null,"updated_at":"2026-11-08T01:00:46.205Z","page_url":"https://treerm.org/trees/acer-pseudoplatanus","markdown_url":"https://treerm.org/trees/acer-pseudoplatanus.md","regions":[{"country":"AT","region":null,"locality":null,"status":"native","note":null,"source_url":"https://www.gbif.org/species/3189870"},{"country":"DE","region":null,"locality":null,"status":"native","note":null,"source_url":"https://www.gbif.org/species/3189870"},{"country":"FR","region":null,"locality":null,"status":"native","note":null,"source_url":"https://www.gbif.org/species/3189870"},{"country":"IT","region":null,"locality":null,"status":"native","note":null,"source_url":"https://www.gbif.org/species/3189870"},{"country":"PL","region":null,"locality":null,"status":"native","note":null,"source_url":"https://www.gbif.org/species/3189870"},{"country":"US","region":"CO","locality":"Denver","status":"recommended","note":"On the Denver Office of the City Forester Approved Street Tree List","source_url":"https://www.denvergov.org/content/dam/denvergov/Portals/747/documents/forestry/Street_tree_guide.pdf"},{"country":"AU","region":"NSW","locality":null,"status":"adapted","note":"Introduced per WCVP","source_url":"https://www.gbif.org/species/3189870"},{"country":"GB","region":null,"locality":null,"status":"adapted","note":"Non-native (introduced by the Roman or Tudor period, naturalised by the mid-1800s); recorded on the GB Non-native Species Information Portal and targeted for removal on protected sites, but not listed on Schedule 9 or banned","source_url":"https://nonnativespecies.org/non-native-species/information-portal/view/25"},{"country":"IE","region":null,"locality":null,"status":"adapted","note":"Non-native and widely naturalised; no official invasive listing found","source_url":"https://www.gbif.org/species/3189870"},{"country":"NZ","region":null,"locality":null,"status":"adapted","note":"Introduced and naturalised on both islands per WCVP","source_url":"https://www.gbif.org/species/3189870"}],"license":"CC-BY-4.0"}
