re-define vegetation classes #27

A thought on vegetation classes. In the Atlas, users can subset to "habitat type", salt marsh/mangrove/sea grass/tidal swamp, and the designations of each of these is determined by the species present in a study's species table. If there is no species table for a study, the study doesn't get a habitat type. Considering that many of our datasets don't have species tables, this is probably worth changing.

But our current guidance for vegetation_class includes:

why not classify these to habitats that are a little more specific, like "mangrove" and "cypress swamp", etc.? This would be more useful and would be easier to designate studies in the map.

David,

Makes sense to go with explicit and specific habitat types rather than vegetation physiognomy. But missing from the "habitat types" would be tidal freshwater marsh. I would recommend changing "tidal swamp" to "tidal freshwater forest", to have parallel construction with tidal freshwater marsh.

Cheers, Greg

  • emergent
  • scrub shrub
  • forested
  • forested to scrub/shrub
  • forested to emergent
  • seagrass

Thanks for the input Greg. We've discussed here and agree revised changes to come soon and I'll comment the updates.

We have the habitat attribute now which allows for more specific classifications. However, there is no vegetation class or habitat which indicates 'tidal freshwater marsh'. Do you have thoughts on this @HolmquistJ ?
