A preliminary study of ants and other free-living arthropods which visited bracken at a post-fire stand was conducted. Eight species of ants visited bracken at the post-fire stand, one month after forest fire. In contrast, only one species visited bracken at the fire-free stand. Ants and other arthropods which visited bracken changed with growth stages of bracken fronds. These findings suggest that ant foraging activity may be affected by environmental conditions, such as vegetation, microclimate, and alternative food resource for ants.
