Field Maple
Acer campestre
Field maple is the tree that fills gaps between hedgerows rather than anchoring a park, usually clipped into a hedge long before it can become anything, so a big one stands out from its own species. We map 8 of them, in 6 cities.
Copenhagen's in Hans Tavsens Park has 4.03 metres of trunk, and the Danish register ranks it third thickest in the country. In Gdansk, the city council protected a pair in Park Oliwski in February 2026 and named them after Hugo Conwentz, the botanist credited with founding the world's first state conservation office. Utrecht's, on the Bartholomeibrug, is the only maple native to the Netherlands among all the city's maples. Prague's, in the Seminary Garden above a pond, carries a careful estimate of 160 to 170 years, and Graz has protected one in the Augarten since 1979, after a 1956 survey had already called it worth keeping.

Copenhagen has two field maples worth crossing town for, and the register tells them apart by numbering: this one is filed as Navr 2.

Utrecht
Every other maple in this city is an immigrant.
Graz
Graz keeps a live public register of its protected trees, and this field maple has held a place on it since the year 2000, growing on the wooded hill above the old town where a fortress once stood...
This field maple carries an unusually solid floor under its age.
