Canopy seed bank
It is often associated with serotiny, the tendency of some plants to store seed in a cone (e.g. in the genus Pinus) or woody fruits (e.g. in the genus Banksia), until seed release is triggered by the passage of a wildfire.
It also occurs in plants that colonise areas of shifting sands such as sand dunes. In such cases, the seed is held in the canopy even if the canopy becomes buried; thus the seed is anchored in place until good germination conditions occur.
