The workings of the network
The way SEDN works needs some explanation to most people. We have an efficient and effective process for working with leading experts in natural history to collect the highest quality data and make it available to everyone.

In summary, we invite people to submit proposals to us saying how much data they will supply and what price they want for it. We simply choose the best value bids. The experts can charge what they like, but they are in competition with each other so it is to their advantage to keep their costs down. In reality, our data providers are volunteers and voluntary groups for whom this funding is a welcome recognition of their value, but they do not make a living from it. This a uniquely effective and beneficial arrangement that demonstrates an ideal model for anyone working with the voluntary sector.
