Why would you want to do that?
Because scientists want to know when plants are losing their leaves, when they're flowering, and many other things. And we want to know it about as many different kinds of plants from as many different places as we can. There are too many plants and too many places for us to do it ourselves, so NEON is asking for your help. It will only take a few minutes, and your data will be very valuable. Please join in.
