A total of 25 unique feature types were captured across the lower Mehi River system via on-screen mapping in February 2022. These features include channel beds, forested and non-forested wetlands, croplands, and constructed features. A total 2,511 polygons were mapped across a combined area of 14,396 ha. Based on their structure and floristics, mapped wetlands were assigned one of 20 plant community types, the most extensive including river red gum tall open forest (PCT 36), coolabah-river cooba-lignum woodland (PCT 39), ephemerally flooded channels (PCT 53a), and permanently flooded watercourse channels and beds (PCT 238a).The layer includes the following key information about each wetland connected to the Mehi River or Ballin Boora Creek:Type (natural, constructed, cropped)Height-CTF (elevation of commence to flow point)Maximum volume (ML)Maximum depth (m)Perimeter length (m)Perimeter length that comprised fringing forest/woodland (m)Various ratings and a final priority score Wall, J.P.
