The goal: to build an evidence base on all the nature in the River Dee watershed i.e. bioregion. The team focused on bird biodiversity over the decades and the rainfall patterns mapped to the river flow. The concept is to build an evidence story of many separate data science projects for each individual part of the watershed and then produce combined analysis or insight on trends etc. that can be shared by local communities, citizen assemblies etc. The data being there to help establish a culture of evidence based decision making the on future health of the bioregion e.g. what impact would bringing back beavers to the watershed have on bird biodiversity?
