ApexRMS is a team of scientists and software developers focussed upon designing and delivering state-of-the-art ecological models and decision support systems for natural resource management.

We provide consulting services and software solutions to government, industry, and non-governmental organizations across North America. Our focus areas include landscape ecology, vegetation and wildlife.

The key services we provide include:

  • ecological modeling
  • decision support system development
  • data analysis and interpretation
  • scientific workshop facilitation



 September 22, 2014: 2nd state-and-transition simulation model conference a success!

Over fifty ecologists, land managers, and decision makers participated in the Second State-and-Transition Simulation Modelling (STSM) Conference, hosted and sponsored by the U.S. Geological Survey, and co-sponsored by the DOI North Central Climate Science CenterThe Nature Conservancy and Apex Resource Management Solutions. The proceedings will be published in early 2015 in AIMS Environmental Science. Find out more at www.stsm2014.org

 May 14, 2014: ApexRMS presents demographic modeling framework at the 15th North American Caribou Workshop

On May 14th, Leonardo Frid presented DG-Sim, a newly released demographic modeling framework, at the 15th North American Caribou WorkshopThe software allows users to simulate population numbers, age structure and sex ratios forward in time under alternative “what-if” scenarios. DG-Sim is a desktop application available for free download; it includes a straight-forward user interface with a simple graphical presentation of results and the ability to import and export model inputs and results from and to Excel.

February 12, 2014: State-and-transition simulation model online conference presentation at the Society for Range Management

On February 12th at the 2014 Society for Range Management annual conference, ApexRMS delivered an online presentation on using state-and-transition simulation models to evaluate alternative land management scenarios.

December 13, 2013: ST-Sim, State-and-Transition Simulation Model Framework Version 2.0, now available for free download

Version 2.0 of ST-Sim, a spatially-explicit State-and-Transition Simulation Model framework, is now available for free download. This version includes fully integrated spatially-explicit capabilities with the ability to work with raster data sets for both model inputs and outputs. A number of important new features have been added to this version including the ability to track pools of stocks (e.g. carbon) and flows between pools (e.g. carbon fluxes). Documentation for ST-Sim is also available online.
