Neat figures

Working with conservation design at a landscape scale necessitates a lot of cool figures.  Here are some of the ones I’ve made with some short explanations. If you have questions, please feel free to contact me.

At the CFL, I’m now working on barrier removal for fish passage. One of the most important figures we use in our presentations shows how important this issue is for fish that move up from the Great Lakes into tributaries to breed. This map shows how much of the potential habitat for migratory fish is unavailable because of impassable dams and road crossings. The blue areas are fully accessible to fish; the grey are somewhat accessible; and the red are inaccessible to fish migrating up from the lakes.

Red shows the inaccessible streams and rivers in the migratory Great Lake fish.


All the inaccessible habitat means there is much less habitat for spawning fish and therefore many fewer fish in the Great Lakes.

For my PhD, I designed conservation priorities for birds in the Southeastern US.  I used a variety of layers with and without focal species to create these maps including SEGAP models, protected areas, and landcover. The end result was maps showing areas of high (warm colours) and low (cool ) priorities  for avian conservation for each landcover type.

At my previous post-doctoral position at University of Maine, I worked to create important herp areas across the northeastern US. I used museum and state occurrence records to create species distribution models in Maxent. Unfortunately, due to data release agreements (necessary because people use publicly available data to collect rare species from the wild), I can’t show a lot of the models or the end results. Instead, here’s a ‘species distribution model’ for vernal pools that I generated for another project.

Vernal pool ‘habitat’ in Maine


The purple and white squares are known vernal pools and the colours differ based on whether the location was used in the test or training set. The colours through Maine represent the predicted probability of suitable habitat – i.e. locations where conditions are likely suitable for vernal pools to occur. The dark colours in most of Maine show  conditions are unlikely for vernal pools, but the teal/green/yellow areas are more likely to be suitable for the pools and associated species.
