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



April 9, 2015: 2nd state-and-transition simulation model conference proceeding papers now in AIMS Environmental Science

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. As of April 9th, two of the papers have been published in this special issue.  Check-in regularly as several more are in peer review. Find out more at www.stsm2014.org

April 9, 2015: We now have a waiting list for  the upcoming introduction to state-and-transition simulation modeling of landscape vegetation dynamics

Registration is now full but you can add your name to the waitlist for the upcoming course: introduction to state-and-transition simulation modeling of landscape vegetation dynamics. This two-day course provides a foundation for developing and running state-and-transition simulation models of landscape vegetation change using the ST-Sim software. The course will be held May 18th and 19th in Fort Collins, CO.

October 8, 2014: ST-Sim, State-and-Transition Simulation Model Framework Version 2.3, now available for free download

Version 2.3 of ST-Sim, a spatially-explicit State-and-Transition Simulation Model framework, is now available for free download. This version adds several important features incliuding parallel processing capabilities for iterations and strata, percentile graphing and control over where spatial outputs are stored. 

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.
