Because the site is used solely for natural history recording, specifically of glow worms, it is very useful to have the recorder’s name so as to avoid duplication of data. Your address is also useful in determining your familiarity with the area being recorded, and also so that I can suggest sites that are local to you. But if you choose not to give your full name or address, the information is still recorded, though with less confidence as to its source.
Your email address is needed in case I have further questions about your sighting.
Sightings are also reported on Twitter, a blog, and on Facebook. However, only sites which you state are publicly accessible, or which are known to be publicly accessible (such as roadside verges) are reported in such detail (six-figure map references), that they can be visited. Sites which are on private property are listed only in vague terms, such as a place name, which would not allow anyone to find the site.
I do not maintain a separate database of contact details, and these are not made available to any outside party. Lists of sites are sometimes provided to researchers, but the contact details are not included in these listings.
