PPP, Participant Code

The participant code, PPP, should indicate the organization conducting the study at your site. 
We have used 3 characters since it is more common for anagrams.  For example:  HVA for Hudson Valley Arboretum

If the study is conducted by an individual, then the PPP should denote the general geographic area. 
An individual could also use initials, but we prefer not to change a Site ID if a new person continues the study on the same site.

If you have any questions, please contact
