Map showing the present distribution of this weed.
Habitat:

Native to the Himalayas, this species is reported to invade, scrubland, plantation forest and forest margins (Webb et al 1988 and Weber 2003).


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; horticulture; pasture dryland

Broad vegetation types
Lowland forest; box ironbark forest; inland slopes woodland; dry foothills forest; moist foothills forest; montane dry woodland; montane moist forest; sub-alpine woodland; grassland; plains grassy woodland; valley grassy forest; herb-rich woodland; sub-alpine grassy woodland; montane grassy woodland; riverine grassy woodland; rainshadow woodland; wimmera / mallee woodland

Colours indicate possibility of Cotoneaster simonsii infesting these areas.

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

1. Restrict human access?Can form dense thickets (Weber 2003). Would require works to create access.

3. Injurious to people?Cotoneaster berries are poisonous if consumed in large quantities (Shepherd 2004).
In 1983-84 1.29% of the reports involving plants made to the Poisons centres in Australia involved a Cotoneaster species (Covacevich, Davie & Pearn 1987).

8. Reduce biomass?Unknown; reported to form dense thickets, which could be an increase in biomass of the woodland that it has invaded, however can prevent the native shrubs and trees from regenerating (Weber 2003). Therefore in the short term biomass may increase, while in the long term a woodland or forest may become a shrubland.

10. Impact on composition
(a) high value EVC
EVC= Grassy Forest (E); CMA= Corangamite; Bioreg= Otway Plain; VH CLIMATE potential.

Establishment
1. Germination requirements?For propagation of cotoneaster species, seed is recommended to be sown in autumn, or stratified over winter and then sown under glass in spring (Griffths 1992). Therefore there is a seasonal component to the germination of cotoneaster species.

Reproduction
9. Reproductive systemReproduces sexually, producing seed (Weber 2003).
Cotoneaster species are capable of layering, where branches that are in constant contact with the ground can set root (Bossard, Randell & Hoshovsky 2000 and PFAF 2002).

10. Number of propagules produced?Cotoneaster species produces abundant fruit, C. simonsii fruit can contain 2-5 seeds (Weber 2003).

mh
11. Propagule longevity?Due to the seeds germinating after a 14 month stratification study on C. horizontalis, seed viability was at 38% (Blomme & Degeyter 1985).
