treeassociated

Treeassociated is an adjective used in ecology, biology, and related fields to describe organisms, communities, processes, or features that are linked to trees or depend on them for habitat, resources, or interactions. The term is applied to organisms that live in, on, or around trees, such as arboreal animals and epiphytic or endophytic organisms, as well as to ecological relationships and functions mediated by trees.

Examples of tree-associated organisms include arboreal insects that dwell in bark crevices, lichens and mosses growing on trunks, mycorrhizal fungi forming symbiotic relationships with tree roots, and endophytes living within leaf or wood tissues. Tree-associated microbiomes encompass bacteria and fungi inhabiting the phyllosphere (leaf surfaces), bark, and rhizosphere around tree roots, influencing nutrient cycling and tree health.

In research, the term helps distinguish processes that are largely influenced by trees from those occurring independently of trees. It is commonly used in forestry, urban ecology, and ecosystem services to describe habitat specificity, canopy-dominated dynamics, and the propagation of species through tree networks. The concept also informs conservation planning, as preserving or restoring tree cover can have cascading effects on a wide range of tree-associated species.
