Other claims from this paper (10)

Observation Horse chestnut is a large deciduous tree native to the Balkan Peninsula.
Observation Native populations total fewer than 10,000 trees and appear to be declining.
Observation Horse chestnut has been widely planted in Europe and other temperate areas since the 17th century.
Observation Horse chestnut occasionally naturalizes in open wooded British habitats.
Observation Horse chestnut has upright white flower panicles up to 30 cm long.
Observation Horse chestnut seeds can weigh up to 42 g each.
Observation Horse chestnut is affected by Cameraria ohridella leaf miner.
Observation Horse chestnut is affected by Guignardia aesculi leaf blotch.
Observation Bleeding canker is expected to kill fewer than 10% of individuals.
Association Leaf miner infestation reduces seed size by 40% to 50%.
