Hi,

You can see the full list of data partners at this link: https://registry.nbnatlas.org/ You will see that there are some individual Wildlife Trusts and the Wildlife Trusts listed.  If you click on their name, you will then see under "Resources" the datasets that are available on the NBN Atlas.

Regards,
Mandy

Hi,

I am not aware that there is a global WT policy, so it is very much down to the individual Trusts regarding the data they share. 
It is great that you want to share your records through the NBN Atlas, so thank you in advance!  I'm not sure where you are based, but there may be other options for sharing your data with us.  If you want to get in touch with me directly feel free to email m.henshall@nbn.org.uk

We don't have anything publicly available for comparing the datasets, but I will see if there is a way that we could do so.  I'll get back to you.
Kind regards,
Mandy

You retain intellectual property over your records, so you should just need to ask them for a copy and then you can pass them on to whoever you like. That assumes they are in digital form etc.

Note that record flow isn't always obvious. About a third of local environmental records centres (LERC) are hosted by wildlife trusts, and most of the rest will be working with the appropriate wildlife trust to a greater or lesser degree, so you may find your records have been shared with the NBN via an LERC and so won't necessarily be branded as a "wildlife trust" dataset but under an LERC banner. Some records may even go more circuitously via county recorders and end up in national scheme datasets. Therefore the best way to tell is to do it backwards and search the NBN atlas for some species and places you know you have recorded at, and see if anything that looks familiar is returned, and then see what dataset it is in.
