As a result, an integrated management approach using introduced seed predators to suppress seed production and selected management practices to reduce seed banks may be needed for effective long-term control in California.Īlexander JM, D’Antonio CM (2003) Seed bank dynamics of French broom in coastal California grasslands: effects of stand age and prescribed burning on control and restoration. We hypothesize that release from natural enemies and competitors together with more favorable environmental conditions in the introduced region may explain the invasion success of G. monspessulana performs better in its introduced region. Thus, seed rain and seed bank size was considerably higher in introduced populations. Fecundity was higher in introduced populations when measured in terms of mature seeds per pod, but lower when comparing seed production per plant (number of pods and mature seeds). Age structure also showed a greater percentage of seedling plants in introduced populations. Mean population density, plant height and stem diameter were greater in introduced populations, with the latter two traits explained by a greater mean plant age. ![]() In this study, the population density and age structure, plant growth and reproductive traits, and seed bank characteristics of 13 native (Mediterranean Basin) and 15 introduced (California, USA) field populations of G. Genista monspessulana (French broom) is native to Europe, but highly invasive and abundant along the Pacific Coast of the USA. Some invasive plants perform better in their area of introduction than in their native region, and this is often attributed either to phenotypic responses and/or to adaptive evolution following exposure to new environmental conditions. ![]()
