In order to be useful for biodiversity conservation and sustainable development, biodiversity information must be not only available, but also accessible.The JRS Biodiversity Foundation contracted an independent study to assess the level to which data produced by JRS-funded projects were discoverable online, and the ease with which those data could be viewed or downloaded. Only about half of the expected data products were viewable or discoverable online, and in many cases data were not clearly connected with project results. Data accessibility was not dependent on the country in which the project was located, and hasn't changed over time. Interviews with grantees helped to identify challenges to and enabling conditions for creating sharable data products. JRS is actively responding to the findings of this study through new planning tools to support future grantees and a data sharing policy that explicitly supports open access to data and data publication to well-recognized and secure repositories.
