mast year

A year in which the crop of mast is good, therefore likely to be favourable for natural regeneration. A good year for oak (Quercus spp.) does not always coincide with a good year for beech (Fagus sylvatica).

This definition is abridged from A – Z of tree terms: A companion to British arboriculture.
