Research output: Chapter in Book/Report/Conference proceedingChapter


A study was conducted to compare wind dispersal of tree seeds in two distinct landscape structure: dense forests and trees scattered in an open landscape, using two mathematical models against extensive seed-trap data collected in an isolated stand of Aleppo pine (Pinus halepensis) in Israel. Results showed that very dense forests produced very restricted seed shadows, with 99.7 m. A significant difference between the distributions of dispersal distances were generated in the low landscape types - dispersal distances in dense forests were considerably shorter than in open landscapes.
