Copses, or small groups of trees, can also be referred to as groves, woodlands, thickets, or clusters. These synonyms can vary in the size and density of the trees within the group. Groves generally refer to a larger and more scattered grouping of trees while a thicket commonly describes a dense and tangled mass of shrubs and small trees. A woodland may refer to an area that is larger than a copse, but smaller than a forest. Clusters generally describe a group of trees that are more scattered and sparse than a copse. Overall, these synonyms provide a range of options to describe a small grouping of trees and the varying densities and sizes they may have.
