John Morgan & Susanna Venn have modelled the dispersal capacity of most of the alpine flora of Kosciuszko (198 species). They found that most species are predicted to have short-distance dispersal (<10m). This highlights the limited ability of Australian alpine flora to disperse and track rapid climate change.
The RCAAE recently hosted a National Expert Elicitation Workshop at La Trobe University (19-21 June 2017) examining the adaptive capacity and functional importance of alpine flora in the face of climate change.
Lead by an expert elicitation facilitator (Anca Hanea, University of Melbourne), workshop participants scored a range of alpine species for their present (2017) and future (2050) vegetative cover, a surrogate for functional importance and adaptive capacity. Participants also began the process of assembling a long-term alpine plot database that could be used to track change in species distribution and cover.
The Research Centre for Applied Alpine Ecology and two of its members, Dick Williams and John Morgan, recently featured in an article in TERN Newsletter (June 2017) announcing that 70-years of long-term monitoring data are now available online via the TERN Data Discovery Portal.
Data supplied by the Research Centre for Applied Alpine Ecology covers 70-years of data from Victorian Alpine Plot Network which has captured a long history of the sites’ vegetation and ground cover condition change, represented by an exceptionally diverse set of population-related observations totaling over 200,000 records.
This data is not only increasing our understanding of impacts such as fire, grazing and exotic species invasions, but also informing land-management decisions by government agencies and private enterprise and helping document a small but important part of the Alps’ natural heritage.
