DIEM’s base-maps are the result of GIS digital information processing that identifies terrestrial and freshwater ecosystems and geological features. They include the following:

Protected Landscape Network (PNL) This set of maps tells a story about Read Island’s network of forests, freshwaters, and other sensitive ecosystems.

Full details and maps.


Sensitive Ecosystem Inventory (SEI) maps ecosystems which are fragile, rare or sensitive to development.

Full details and live map.


Enduring Features maps biophysical attributes that influence and sustain the area’s ecosystems.

Full details and live map.


Watersheds Analysis DIEM’s mapped data enables digital filtering processes to measure and illustrate a variety of past, present, proposed, and cumulative impacts.

Community Maps Last but not least, citizen mapping adds important real-observations and our own stories that help to document what was and what is – as well as what’s important for the future.

DIEM | A community-based mapping project

In this magnificently beautiful place of remote wilderness, small communities, and industrial resource use, impacts and planning decisions are happening without complete information, and partial ecosystem data that exists is not presented in a way that non-professionals can understand. Stewarding this area’s unique and valuable natural resources requires identifying and quantifying what is here – and making the information accessible to everyone.
