Adrian has computerised his own records and those from SBIS card indexes. He has also obtained a large volume of records from N.R.A., which he has been able to transfer to his computer files. A website on the Freshwater Invertebrate Survey of Suffolk contains checklists, photos and maps of selected species. Adrian has established a Cladocera Interest Group to encourage improved recording of Water Fleas.
