Thank you so much, Carrie!
I suspected it had too many vectors, but did not even think about all of the observations that it would include. I had two reasons for trying to create it. The first was my own reason of wanting to use it to subtract all of those marine observations (in a project) from the one other place I had created, which was meant to capture only the observations from northern California forests of coastal influence, and ended up getting the beaches, as well. Obviously, I should have just created a place for the forests, but I do not know how to create a place with more than one polygon, and the coastal forests are not adjacent to each other the way the coast beaches are, so I ended up including the beaches in my first place, which was not really what I needed for this new project, which is just about forest inhabitants. (It had worked for my original project that I created it for, because that was specifically about ferns, so having the beaches in there was fine, but now I am trying to repurpose it to work for all of the forest flora and fauna, and I don’t want sea creatures, seabirds, beach plants, etc.)
The second reason, I rationalized, was that “who wouldn’t want a place that included just the beach and marine life of CA?” But as you have pointed out, I have bitten off too much, here, so have to rethink the whole thing.
Pity, because it took about an hour to make that polygon. Please let me know if you have any better ways for me to approach this. My two goals are to create something useful for everyone, and to create something that works for the Northern California coastal forests project.
Thanks again!
