streams & rivers


Search for critical interactions

Channel types, aquatic habitats, fish-eye view of riparian - erosion - road - fire - climate change conditions.

 riparian zones

Optimize riparian zones.

Riparian vegetation, shade and thermal energy, best locations to increase shade, in-stream wood recruitment, thermal refugia

floodplains & valley Floors


Locate ecological hotspots.

Floodplains and valley floor landforms, flood hazard zones.  

topography, erosion& Roads


Prioritize activities

Landslide, debris flow and gully potential, road erosion, optimize new drains and surfacing, road stability, roads in floodplains, and habitat length above all crossings. 

wildfire & Climate Change
