Natural resource management and decision making require tools to assess the trade-offs between alternative choices. Our Ecological Modelling team has many years of experience in the design, development, and application of models and environmental information systems in the areas of aquatic and terrestrial ecosystem management. Many of these models are designed using the approach and methods of Adaptive Management. As the success of a resource management model is defined by its actual use, we work closely with our clients during all stages of model development and implementation.
ESSA’s approach to Ecological modelling includes:
- Planning and multi-stakeholder participation: conducting workshops for scoping, issue definition, knowledge engineering, model design, and the development of adaptive management plans.
- Scientifically credible models: developing, applying, and assessing computer simulation models, to explore alternative scenarios, trade-offs and management options.
- Monitoring and auditing: increasing understanding through the design of monitoring programs and analysis of results that is critical to adaptive management.
Our approach has produced successful models that are used throughout North America. In addition to the development, documentation and implementation of models, we provide:
- training and user support
- assessment of the decision support requirements of resource managers
- reviews and syntheses on the state of the science related to ecological modelling
- model audits and assessments that examine model performance and integrity
- development of strategic management plans and research programs
Training in landscape modelling tools
We regularly provide these courses for clients such as the U.S. Forest Service, and sessions are scheduled throughout the year when numbers permit. Those who are interested in the courses may contact the Training Coordinator for course dates and registration information.
We can provide customized training courses in these tools for any interested organization. The costs for each of these courses are provided on the individual course pages:
- Landscape modelling using ESSA’s TELSA and VDDT models.
- The Yukon Habitat Suitability Model, for predicting the suitability of habitat for Chinook salmon in reaches and watersheds within the Yukon Territory; Fisheries and Oceans Canada and Yukon Placer Secretariat.
- Simulation modelling of caribou in the Arctic; Canadian Wildlife Service / University of Alaska.
- Integrated modelling of moose habitat and population; Lakehead University / Canadian Forest Service.
- Develop a consistent, reliable framework to identify at-risk streams in BC that would benefit from protection through Temperature Sensitive Stream (TSS) designation; Ministry of Environment, British Columbia.
- Develop and evaluate a simulation model of the potential aquatic environmental effects of large nuclear generating stations; Ontario Hydro.
