Everyone can see the coordinates unless the taxon is threatened.
Public coordinates shown as a random point within 10KM of the true coordinates. True coordinates are only visible to you and the curators of projects to which you add the observation.
Coordinates completely hidden from public maps, true coordinates only visible to you and the curators of projects to which you add the observation. Observations with private coordinates will still be used to verify place check lists.
I see that the Monterey Bay California Native Plant Society lists two species of Calandrinia in this area, C. breweri and C. ciliata. Not sure what I have here but now I know I have to look closely before leaving the field.
