Short‐term seed survivorship for several species of the Queensland rainforest was compared in forests and early successional fields, treefall gaps and forest interior, and an array of microhabitats (tree buttresses, logs, forest floor with and without leaf litter cover). Seed survivorship was lower in forest than in field at one site, but equal at another. No differences were found in and out of treefall gaps, in contrast to several other studies. Microsites had little consistent influence on short‐term seed survivorship. A survey of the literature showed no consistent habitat or microhabitat patterns in seed survivorship.
