Mapping of a rare plant species (Boronia deanei) using hyper‐resolution remote sensing and concurrent ground observation

Boronia deanei is one of many declared rare, and potentially threatened, species of the Australian flora that occur within freshwater swamps and riparian margins. However, a lack of knowledge regarding its ecological distribution and habitat requirements may result in vulnerability to current and planned anthropogenic activities. Identification of population boundaries, numbers and locations should be highly beneficial for developing appropriate conservation approaches. This study demonstrates (i) the potential of converging hyper‐resolution remote sensing imagery with targeted ground observations to identify individual population extents and densities and (ii) proposes methods of defining and mapping suitable habitat and potential extents for rare plant species in areas potentially exposed to multiple anthropogenic impacts.
