Making the most of existing data in conservation research

Much attention in recent years has been focused on making biodiversity data open and accessible to researchers. Yet ensuring the availability of these data is only the first step in preventing data waste. Here, we argue that researchers need to do a better job of using available datasets. We recommend that researchers search for existing data sources to serve their needs first, that they work to integrate multiple data sources when one alone will not suffice, and that they aim to explore research topics that will directly inform conservation action. We provide a roadmap with resources and examples to help guide conservation researchers towards better data-use practices. The vast quantities of biodiversity data, coupled with advanced techniques for using and integrating datasets, will play a key role in determining how to halt biodiversity declines. Making data open and accessible is only the start; we must be sure that we are using that existing data to conduct further research and inform decisions.
