Because F. alnus has frequent seed crops in sunny areas and can form seed banks in nearby forests (Frappier et al 2002), it is likely to continue increasing in pine forests in the northeastern US for the foreseeable future. White pine does not regenerate under a closed canopy." Habitat alteration: Fagan and Peart (2004) state that, "F. alnus altered the relative abundance of seedlings towards a shade-tolerant species (sugar maple)." Reduction in native biodiversity: In the study conducted by Fagan and Peart (2004), they state that, "F. alnus in the forest understory clearly reduced the extension and radial growth of saplings of all species. F. alnus has an extensive shallow root system (M.E. Fagan, pers. obs.) and may be a strong below-ground competitor." Last Modified: 8/07/2005 11:57:02 a.m.
