Interpreting or reading landscapes is often question driven.
- Where are the best fish habitats located in a watershed?
- Where are the largest floodplains?
- Where does urbanization impact the best aquatic habitats?
- Which areas are most prone to shallow landslides?
- Where are forest roads most at risk from failure?
- Where is the highest potential for road surface erosion and sediment delivery to streams?
- Where does the greatest wildfire risk overlap the greatest climate change?
Topic 1: Aquatic/Riparian Habitats
- Where is the best fish habitat located for different species (anadromous, resident)?
- How can I locate areas of concentrated high quality fish habitats, e.g., habitat core areas?
- Where are my aquatic biological hotspots located?
- Which channels would support beaver?
- Where are the channels located with the greatest habitat diversity?
- Where are the largest and most productive floodplains located in my watershed?
- Map estuary habitats.
- Calculate the cumulative length and quality of fish habitat upstream (or downstream) of any point in the river network (including all road crossings).
- Classify, by subbasins, aquatic or fish habitats across a large watershed or landscape.
- Where in my watershed are channels with the greatest susceptibity to disturbances (or dynamics)?
- Identify where the best habitats intersect potential environmental stressors.
Topic 2: Channel Types, Channel Response, Channel Network
- What are the different channel types in my watershed and which ones are the most sensitive to land use impacts?
- Which areas of the channel network are most prone to sedimentation and flooding?
- How many stream orders do I have in my watershed?
- What is my watershed's drainage density?
- What different types of channel geometry do I have in my landscape?
- Which parts of my channel network are most prone to disturbance (floods, sedimentation, landslide impacts), an important consideration in the context of in-stream restoration?
- What types of information can help with my in-stream monitoring program?
- What types of information will help with my floodplain restoration activities? How can I locate floodplains that have been obscured by development?
- How can NetMap help with in-stream restoration?
- How can I identify estuaries or portions of them that have been obscured by development and in need of restoration?
Topic 3: Topography/Erosion/Slope Stability
- Which hillsides in my watershed are most prone to landsliding?
- Which headwater streams are most susceptible to debris flows or gullying?
- Which fish streams are most susceptible to debris flow impacts?
- How can I identify large landslides and earthflows?
- Which areas in my watershed are most at risk from debris flows?
- Which landslide prone areas are most sensitive to land uses?
- Which structures are at risk from landsliding and debris flows?
- What parts of my watershed are most likely to contribute sediment to river channels?
- Where is the highest surface erosion potential with a high likelihood of sediment delivery to streams and rivers?
- Classify watershed subbasins by inherent erosion potential.
- What proportion of landslide potential originates from particular areas of my watershed?
Topic 4: Human Infrastructure - Roads/Pipelines
- Which subbasins across the landscape have the highest road density?
- Which individual hillsides (approximately 0.1 km2 [24 acres]) have the highest road density?
- Create a fish-eye view of road density.
- Which roads have the highest road drainage diversion potential?
- Which road segments have the highest road surface erosion potential?
- Which road segments/energy corridors are located on potentially unstable hillsides?
- Which road segments/energy corridors are most likely to trigger debris flows in steep headwater streams?
- Which road segments/energy corridors are most susceptible to damage from debris flows?
- Where do roads/energy corridors intersect floodplains?
- Where do roads/energy corridors intersect quality aquatic/fish habitat?
- What is the cumulative habitat length and quality above every road crossing (or below every road crossing)?
Topic 5: Riparian Management
- Which streams are most sensitive to radiation loading if the riparian vegetation was altered or destroyed?
- At a point in time (this year), how does variation in riparian conditions across my watershed affect in-stream wood loading?
- Using forest growth predictions, calculate how in-stream wood loading will vary over time (decades to centuries).
- What types of in-stream wood jams would I expect, given variation in riparian vegetation?
- Could predicted fish habitat quality influence the design of riparian management, including buffers?
- Should I consider erosion potential in the design of riparian management?
Topic 6: Wildfire (Pre and Post)
- Where in my watershed is the greatest chance of wildfire? Where is the highest 10% or 1% of fire risk located?
- Where is the predicted highest fire severity located across the landscape?
- Where does the highest chance of fire overlap with the highest fire severity? Where are those stressors located?
- Where does the highest fire severity overlap with the highest chance of post wildfire erosion?
- Where does the highest fire risk overlap with the highest fire severity, and where do those overlap with the best aquatic habitats?
- Where in my watershed is the highest burn severity located? Top 10%, top 1% etc.
- Where is the post fire surface erosion potential the most extreme?
- Where is the post fire landslide and debris flow risk the highest?
- At what locations does the highest fire severity overlap with the highest erosion potential, and where do those locations overlap with quality aquatic habitats?
- Where do roads intersect burned areas with the highest erosion potential?
- Which streams in the burned area have the highest exposure to increased thermal loading because of loss of riparian vegetation?
Topic 7: Climate Change Vulnerability
- Identify the largest predicted climate change in your watershed for temperature, precipitation, snow accumulation and summer and winter flows.
- Where do the largest predicted changes in temperature and flow intersect the highest fire risk?
- Where are the largest changes in summer flow predicted to occur and where does they intersect sensitive and valuable aquatic habitats?
- Where are the largest changes in winter flow predicted to occur and where do they intersect valuable habitats and infrastructure, such as roads?
