For deciduous trees and shrubs - is the plant leafing out, fully leafed out, showing fall foliage color (or dry season foliage cover), or bare?

Hi! I had created this for a Vermont project, where it was loosely based on leaf colors because I look at lots of aerial photos and was trying to figure out the timing and color for each tree species. However, it seems like people are using this field on a larger scale. This is great, and maybe it would be better just to lump 'some color', 'past peak' 'dry' etc into a field for when leaves are still on a tree but no longer green/ I don't really need the fine color gradations because I kind of just wrapped my projects into the big Vermont one anyway, and besides I can see it from the photos. Any thoughts? It might also make sense to differentiate drought deciduous species from cold deciduous species, or add a field for plants that have no/few leaves because of non-strictly-seasonal factors such as insect defoliations. Thoughts?
I also noticed that some are using 'peak foliage' for green leaves rather than orange/red/yellow ones. Is there a way to fix this without harassing those people? I guess i just forget how global this website is :)
I can lump if you tell me how we should do it. I'll defer to you but I think a simple general Leaf Phenology field would be really useful
For now maybe just combine Dry | Some Color | Peak Foliage | PastPeak ? I am trying to think of a short way to describe when leaves are still on a plant but aren't green anymore, without referring to new England foliage. 'Entering Dormancy' might work but isn't very straightforward and I see that even 'Peak Foliage' caused confusion so I don't want to use that. Maybe we should also change 'Leafed Out' to 'Fully Leafed Out'? What do you think? Thanks!
Hey Charlie, how is Leafed Out different from Peak Foliage and how are Dry/Some Color/PastPeak distinguished?
