Habitat structure defined as the composition and spatial arrangement of physical environments is a factor controlling distribution patterns of plant species. In tropical forests, vascular epiphytes show uneven distribution which perhaps be caused by the heterogeneous habitat structure associated with tall and complex forest structure. However, due to the difficulty accessing tropical forest canopy, little is known how habitat structure influences spatial distribution of vascular epiphytes. To clarify this point, we examined the relationship between habitat structure and spatial distribution of 32 species of vascular epiphytes in a tropical montane forest of northern Thailand. Within forest stand, we recorded the distribution of each species and measured habitat structure at the attached points (height, diameter, and angle). According to the canonical correspondence analysis, habitat structure significantly influenced the spatial structure of vascular epiphyte communities but explained about 10% of variation. Our results suggest that the spatial structure of vascular epiphyte community is influenced by habitat structure but it can be explained more by other factors such as microclimates and biological interactions.
