Invasion by woody shrubs and trees

Chapter


Abstract


  • The invasion of many habitats by exotic shrubs and trees has been an important factor

    causing changes in Australian native vegetation through declines in species richness,

    changes to community composition and reducing ecosystem function (Lindsay and

    French 2004; Gosper eta!. 2006; Mason and French 2007; Gooden et at. 2009). Costs

    of management have been high (Sinden et a!. 2004) and research into management

    options extensive. Whilst management-oriented research places Australia at the leading

    edge ofthe field (Briese 2004), this has been at the expense of research testing hypotheses

    about mechanisms of invasion in Australia.

    Information on the novel distribution, population dynamics and ecology of the majority

    of invasive species is largely unknown. Ten species of exotic woody shrub or small tree are

    among the 20 Weeds ofNational Significance (WoNS) classified by the Australian Federal

    Government, reflecting their extensive current and/or projected impact on native and

    agricultural communities. Funding for weed research is largely focused on these WoNS

    but directed specifically to the development of successful management options. Very little

    is directed to understanding invasion or impacts. Additionally, a further 100 shrubs and

    trees (and more herbs, grasses and vines) are known as significant environmental weeds

    and described in a range ofland management resources (e.g. http://www.weeds.org.au).

    Almost nothing is understood about these species. Many invasive shrubs and trees have

    invaded from horticultural stock, and the species may differ from native stock (e.g. Lantana

    camara L., lantana, Figure 13.1) causing difficulties in both management and in understanding

    ecological consequences.
