Fire is a key driver of landscape change, and there is feedback between the state of the landscape and the size and severity of fire.

ESSA provides services to help predict the impact of fire and to show how that impact can change over time with changes in fuel and vegetation, based on tree growth, mortality, and management. This information can help managers make decisions about fuel treatment options in forested landscapes.

Simulation models are useful tools for assessing the potential consequences of proposed management actions over the medium to long term at a landscape scale. Landscape level models allow for the evaluation of management actions on indicators such as wildlife habitat supply and fragmentation, timber flow, fire regimes and invasive species.

ESSA has extensive experience developing, applying, and training others to use tools for both non-spatial and spatially explicit modelling of terrestrial landscapes. ESSA has developed the Vegetation Dynamics Development Tool (VDDT) and the Tool for Exploratory Landscape Scenario Analyses (TELSA)  and applied these tools to various landscape management problems throughout North America for clients ranging from provincial, state and federal governments to NGOs.
