A new field for sorting observations observed in human-influenced landscapes

Lately I've been tracking observations by natural community type, as defined in Vermont with the book Wetland, Woodland, Wildland. (other states and countries have different classification systems). For instance, see Northern Hardwood Forest, Vermont's most widely distributed natural community:

Note that it ranks the species by number observed. It's not systematic, as i don't record every species every time, but it gives you an idea of what species you will see in each natural community.

After the idea independently coming up in several different places the last few weeks, I've decided we need a field to track different human-influenced habitats as well. Urban nature is a whole other world than natural ecosystems... but every bit as interesting and often not as well studied. Both are worthy of attention, but the nature where people live is the easiest for most people to see from day to day.

To make sure things are standardized, since there's no book to anchor to, i've proposed a bunch of categories. Others are free to propose others. Once we start using them it becomes a bit of a pain to change them with a bulk edit, so I wanted to run them by a few other users first. Here's my current list:

road/railroad/trail right of way
utility right of way
mowed lawn (includes home lawns, sports fields, playgrounds, etc)
Human-created open field (cut every year or two, but not a mowed lawn. Like many fields around homes in VT)
Disturbed wetland (cut over every year or two like open field but is wetland
agricultural area (farms)
Dense Urban Center (parking lots, cracks in sidewalk, etc)
Abandoned Urban Center (vacant buildings etc)
landscaping or garden (where plants are planted, pollinators may appear, weeds, etc)
managed forest or plantation (this one can intergrade with wildland since most areas are managed in some way but thinking of high intensity managed areas)
Invasive Species Infestation
Storm Drain/Channelized Waterway
Artificial Pond
Stormwater pond/sump/catch basin
Indoors (spiders, etc that find their way indoors, birds in airport terminals, etc)

I don't want to create too many but nor do I want to leave too much out. I'm not sure if these would work globally, but they seem good in the northeastern US. Once i get this field set up we can start seeing what species are in each one. Any thoughts? Thanks to @erikamitchell @srall @jogarton for being part of this discussion so far. Not sure who else might be interested. @bouteloua @kueda @kpmcfarland @cullen @sambiology @silversea_starsong perhaps? Feel free to tag others. Also feel free to use the natural community field, but if you're in Vermont let's use Wetland Woodland Wildland.
