19:30 (2 hours)The Rich North Sea Toolbox Session
(Limited to 50 people. Sign up upon registration, food provided.)
Ever wonder what other oyster restoration projects are going on? Do you want to know where you can acquire Bonamia free oysters? Would you like to have a map available with all current restoration efforts? Are you curious about broodstock structures and other outplacement methods? The Rich North Sea wants the same! That’s why we are building The Toolbox: a website filled with information on nature enhancement, practical lessons and inspiring projects. But we can’t create the Toolbox alone. This living document needs your input! We are keen on showing you the first version of the Toolbox and hearing your opinion on design and content. We would like to work together to create something which can and will be used by us all. Join us on Tuesday evening. Please bring your laptop or tablet if you have them.
