Prescribed burning of French broom. Pan-Pacific Entomologist, 71 2: It is also an emerging environmental weed or “sleeper weed” in Western Australia and was recently listed as a priority environmental weed in six Natural Resource Management regions in south-eastern Australia.
For individual large plants, weed wrenches assist targeted removal, but can disturb the soil prolonging the need for monitoring for regeneration Bossard, Seedlings are least resistant to hormonal herbicides at the to cm size Bossard, The species is native to the Mediterranean region, and is considered an invasive plant in most places where it has been introduced.
In exotic populations, the historic horticultural importation and associated hybridization activities with other species in the Teline group suggest genisga exotic populations may nonetheless exhibit genetic variation and as such may not be identical to native G. These include five other Genista species and members of the genera Cytisus four speciesRetama two speciesCalicotome one speciesSpartium one species and Ulex one species Holm et al.
It is native to the Mediterranean region. It has been estimated to invade at leastha in Australia. Kahsay-Berhe, Tothill JC, In the field, G.
Genista monspessulana (Montpellier broom)
Peterson DJ, Raj Prasad, Mechanical control does not deal with the long-lived seedbank and so integrated strategies associated with reseeding desirable species, or at least allowing those present to seed effectively, are often required Bossard, The legume-feeding psyllids Homoptera of the west Palparctic Region.
Pan-Pacific Entomologist, 74 1: Brill, Leiden, Netherlands, It has become a major widespread weed in native and commercial forest ecosystems, in disturbed habitats, and along water courses. Cape broom Genista monspessulana is similar to flax-leaf broom Genista linifoliaMadeira broom Genista stenopetalabroom Cytisus scoparius subsp. Agricultural Practices Spread is known to have occurred via movement of farm equipment, and through the activities of grazing livestock through semi-natural vegetation systems Parsons and Cuthbertson, Seed production increases asymptotically with plant age for all populations, peaking at ca.
Hnatiuk, ; Parsons and Cuthbertson, Cape broom Genista monspessulana is the most widespread of several broom species that have invaded southern Australia and was recently determined to be infesting over hectares in south-eastern Australia. Garcia-Barriga and Forero, Shrub or Subshrub Genista monspessulana L.

A study of such variation is required to clarify such suppositions. Komarov, ; Grossheim, Natural enemies that monspsssulana caused noticeable damage in the native range sufficient to affect Montpellier broom growth and spread are listed in the table. Seed pods are rusty brown, covered with silky hairs, usually with seeds per pod. US Fish and Wildlife Service, a. Chemical composition of the forage and conclusions. The upright spreading growth form, height, leafy spineless shoots, and racemes of showy flowers are common to all members of the Genidta group in contrast to the ‘genistiform’ tussock of vertical leafless shoots shape of other Genista species.

Impact Top of page No economic assessment of G. Regional differences in the distribution of the pyralid moth Uresiphita reversalis GuenTe on French broom, an introduced weed. In the native range, goats are probably another significant factor limiting the abundance of this plant, given their ubiquitous occurrence, and that most Mediterranean species in the Genisteae are spiny.
Age structures in the native range are mostly bell shaped with age classes of years dominant, few new recruits and few older plants Lloyd, Recent phylogenetic analyses suggest all species tested in Teline are closely related to two tenista represented by G.
Taxonomic Tree Top of page Domain: Stands of French broom can be so thick that they make meadows and pastures useless for wild and domestic animals. Annual growth is such that axillary meristems, produced on the main axis, grow up into lateral vegetative shoots at the same time as extension of the main axis.

Goat management may require the provision of access trails and follow-up herbicide treatments on resprouts once the goats have been moved on. A French monspesslana control project. The uppermost petal i.
A widely naturalised species that is mostly found in the temperate regions of southern Australia. Currently only four species seem likely to be specific to G. In its native range, broom is a calcifuge Polunin and Smythies,
