Louise McRae's research is centred on looking at broad-scale patterns of biodiversity over time.

She has worked extensively on the development of the biodiversity indicator, the Living Planet Index (LPI), which is a measure of the changing state of global biological diversity, based on abundance trends of vertebrate species from around the world.

Through the development of the method and the increase in the data set behind the LPI over the past few years, Louise has been able to examine vertebrate trends for different regions of the world and for various subsets of species. Many of these results have been used to communicate biodiversity trends to a wide audience from policymakers, and scientists to the general public. She has led ZSL’s contribution to many of the biennial Living Planet Reports, WWF’s flagship publication on the state of the natural world.

Louise's research interests lie in understanding the way we use and aggregate data to measure trends in biodiversity; how much and what type of data are needed, and how can the temporal, geographic and taxonomic gaps in biodiversity knowledge be addressed? She is also exploring how indicators can measure biodiversity beyond the species concept, exploring cultural, economic, livelihood and ecosystem values.
