Developing a Comprehensive Terrestrial Habitat Map for the Northeastern U.S. and Atlantic Canada to Inform Planning Decisions

Extending the Northeast Terrestrial Habitat Map to Atlantic Canada

The Northeast United States and Atlantic Canada share many of the same types of forests, wetlands, and natural communities, and from a wildlife perspective the region is one contiguous forest. However, resources are classified and mapped differently on the two sides of the border, creating challenges for habitat evaluation, species modeling, and predicting the effects of climate change. To remedy this, ecologists from The Nature Conservancy collaborated with a committee of scientists from various Canadian institutions to produce the first international map of terrestrial habitats for northeast North America. The project used extensive spatial data on geology, soils, landforms, wetlands, elevation and climate. Additionally, all four [...]

The methods we will use to create this map were developed and refined during the three-year period in which we produced the Northeast Terrestrial Habitat Map. They make extensive use of field-collected data combined with national and provincial datasets. Early in the project much time will be committed to the compilation and development of spatial datasets of important environmental variables, and in compiling numerous plot-based samples of various ecological systems. The modeling process combines the plot-based samples, tagged to the correct ecological system, with the region-wide GIS data layers. Regression trees are used to identify the variables that best delineate the ecological systems, and then to model those systems. This final map is a composite of the individual models. Structural attributes like canopy density and datasets related to vegetation height and biomass may have a role in detailing forest successional stage.
