Common barberry (Berberis vulgaris)

Present distribution


Scientific name:

Berberis vulgaris L.
Common name(s):

Common barberry

This weed is not known to be naturalised in Victoria
Habitat:

Native to temperate Asia and Europe. Found on roadsides, woods, old fields from 0-1800 m (FNAEC 1997). In New England, found in abandoned fields, coastal grassland, early successional forest, flood plain forest, forest wetland, open disturbed area, pasture, planned forest, roadside, shrub wetland, vacant lot, garden (IPANE 2004). Not known as naturalised in Victoria (ANH 2006, DSE 2004).


Potential distribution

Potential distribution produced from CLIMATE modelling refined by applying suitable landuse and vegetation type overlays with CMA boundaries

Map Overlays Used

Land Use:
Forest private plantation; forest public plantation; pasture dryland; pasture irrigation.

Broad vegetation types
Coastal scrubs and grassland; coastal grassy woodland; heathy woodland; lowland forest; inland slopes woodland; sedge-rich woodland; montane dry woodland; grassland; plains grassy woodland; herb-rich woodland; montane grassy woodland; riverine grassy woodland; riparian forest; rainshadow woodland; Mallee woodland; Wimmera/ Mallee woodland

Colours indicate possibility of Berberis vulgaris infesting these areas.

In the non-coloured areas the plant is unlikely to establish as the climate, soil or landuse is not presently suitable.

Social
1. Restrict human access?Grows between 1-3 metres (FNAEC 1997). Found on roadsides, woods, old fields. In the US was commonly cultivated for thorn hedges (FNAEC 1997). Depends on where the plant is found but if grown in dense thickets then would have a high nuisance value.

mh
2. Reduce tourism?Flowers in spring. Red or purple berries (FNAEC 1997). In the US was commonly cultivated for thorn hedges (FNAEC 1997). Depends on where weed is found but has the potential to have a minor effect on both aesthetics and inhibit some recreational activities.

7. Increase soil erosion?Deciduous shrub (FNAEC 1997) so will leave areas of ground exposed at certain times of year. However, information available doesn’t refer to increases in soil erosion and because of the areas found it is likely to have only a low probability of large-scale soil movement.

8. Reduce biomass?Grows between 1-3 metres (FNAEC 1997). Found on roadsides, woods, old fields. In these situations it is likely that biomass will slightly increase.

10. Impact on composition
(a) high value EVC
EVC=Coastal headland scrub (BCS = V); CMA=Corangamite; Bioreg=Warrnambool Plain; CLIMATE potential=VH. Grows between 1-3 metres. Other species of Berberis documented to replace native plants (Weber 2003) but insufficient evidence to determine if B. vulgaris does the same. May lead to minor displacement of some dominant species within the lower strata.

(b) medium value EVCEVC=Riparian shrubland (BCS = D); CMA=North East; Bioreg=Northern inland slopes; CLIMATE potential=VH. Grows between 1-3 metres.

Stress tolerance to frost, drought, w/logg, sal. etc?Cold hardy at beginning and end of growth period. ‘Purple-leafed plants were more salt- and pollution resistant than the green-leafed ones’ (Mamaev & Semkina 1972). Not frost tender (PFAF 2004). ‘Cannot tolerate extreme maritime exposure’ (PFAP 2004). Other species of Berberis are known to be drought tolerant and susceptible to fire (Weber 2003). Tolerant of at least 2 and maybe tolerant of another.

10. Number of propagules produced? For other species of Berberis, seed density is high (Weber 2003). Each fruit contains 1-3 small black seeds (IPANE 2004). Plant images indicate that each plant can produce greater than 1000 fruit so propagules produced per flowering event would exceed 2000.
