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



October 27, 2015: State-Transition Simulation Modelling For Quantifying Rangeland Composition, Structure and Fuelbed Components

This webinar demonstrates how conceptual state-and-transition models from NRCS ecological site descriptions can be quantified and used to consider the impacts of alternative management scenarios on rangeland composition, structure and fueldbed components.  Read more here... 

October 26, 2015: Early Registration for the Introductory Course on State-and-Transition Simulation Modelling with ST-Sim Closes November 1st

The early registration deadline for the Introduction to State-and-Transition Simulation Modeling of Landscape Dynamics is November 1st.

This two-day course will be held in downtown Durham’s historic entertainment district, and a short walk from Duke University campus. The course provides a foundation for developing and running state-and-transition simulation models of landscape change using the ST-Sim software.

May 28, 2015: Using State-and-Transition Simulation Models to Guide Sustainable Management of Ecosystems: Three Case Studies from across the US

The USGS National Climate Change and Wildlife Science Center has published a webinar of three case study applications of State-and-Transition Simulation Models to guide sustainable management of ecosystems. Read more here...

April 20, 2015: ST-Sim, State-and-Transition Simulation Model Framework Version 2.4, now available for free download

 Version 2.4 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 the ability to define age classes and aggregate/dissagregate model outputs by age.

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
