Integrating spatial and temporal assessments of vegetation condition using VAST2
This audio slideshow is the verbatim record of a presentation given to the Murray Darling Basin Authority, Canberra, ACT on 28 February 2014.
The slide show tells the story of how land management practices effect vegetation condition in space and over time. Change and trend in vegetation condition can assessed using the VAST framework, involving modification and reference states and criteria and indicators. Indicators are populated using time series remote sensing datasets and other sources of information including ecological models. The audio slideshow describes how environmental flows (i.e a land management practice/s) can be tracked and reported using ecological criteria. The issue of which data are ‘fit for this purpose’ is discussed, highlighting caution regarding using vegetation dynamics remote sensing datasets as synonymous with vegetation condition.
Charlie Massy talks benefits of applying VAST-2 system at paddock level on Severn Park
Charlie Massy discusses the major landscape transformations which have occurred to the native pastures on the Monaro; a result of a long history of the effects of land management practices. Grazing on Severn Park started in the 1830s. Pastures of Severn Park are situated two geologies: dry tussock grasslands situated on low rolling basalt hills and the grassy open woodlands located on granite hills.
