Abstract:

Global monitoring of biodiversity status and trends is a critical component in not only the reporting of biodiversity change but also for the strategic deployment of conservation resources. Ideally status and trends should be estimated at spatial scales that are relevant to both ecological processes and the anthropogenic processes that are driving change in the landscape. Here Andrew will present the BILBI modelling framework, the engine behind two new global biodiversity indicators – the Biodiversity Habitat Index (BHI) and Protected Area Representativeness and Connectedness Index (PARC). Using community - level biodiversity modelling of species turnover (beta diversity) across a landscape for three separate biological groups (vertebrates, invertebrates and plants) and pairing these with time - series of habitat loss (BHI) or protected area coverage (PARC) Andrew and his team are able to estimate loss (BHI) or level of protection (PARC) for biologically unique environments through time. These estimates can then be used to report progress against Aichi Targets 5 (habitat loss) and 11 (protected areas). By generating continuous predictions across a fine - grained ( 1 km) grid of the world’s terrestrial areas, these new biodiversity indicators are capable of producing results for individual pixels or scaling up estimates to any required level of spatial aggregation above this ; e. g. country, region, continent or the entire planet.

This talk will focus on the advances in modelling techniques and infrastructure that have enabled establishment of the BILBI framework including the use of a new modified version of Generalised Dissimilarity Modelling for sparse presence - only biological data, advances in model fitting procedures, big - data management, and refinement of environmental covariates, including climate and land use.

Biography:

Mr Andrew HoskinsAndrew Hoskins is a community and behavioural ecologist who is interested in using novel spatial modelling techniques to solve ecological questions. He completed his PhD at Deakin University studying the at - sea foraging behaviour of Australian fur seals using a combination of animal - borne bio - logging equipment, remote sensing information and physiological analyses.

In 2014 he joined CSIRO Land and Water as a postdoc in the Macroecological modelling Team under Simon Ferrier. During this time he worked to develop methodological solutions that allowed the generation of a new set of global biodiversity indicators. He has recently moved to Townsville as part of CSIRO Health and Biosecurity, where he plans to bring his previous experiences together in a project that assesses the fine - scale distribution of large feral mammals in Northern Australia, through large - scale deployment of bio - logging and environmental sensor equipment.
