Maintaining habitat connectivity under scenarios of climate and landuse change

ApexRMS is collaborating with the Quebec Government and Andrew Gonzalez from McGill University to assess forest habitat connectivity within the St. Lawrence Lowlands under scenarios of climate and landuse change. We recently published a report and webinar identifying connectivity conservation priorities based on current land use and land cover. Work is now underway to combine climate projections with land use and land cover projections (using ST-Sim) for the St. Lawrence Lowlands so that we can identify priority areas to protect that have a higher probability of maintaining habitat connectivity into the future.

Online course in developing state-and-transition simulation models of landscape change using ST-Sim: March 19-20, 2019

ST-Sim course + workshop on modeling land use change and carbon: June 12-14

Course & Workshop

Sponsored by

California Air Resources Board

U.S. Geological Survey

Apex Resource Management Solutions

This unique event begins with a two-day online course on the fundamentals of developing state-and-transition simulation models of landscape change, followed by an optional one-day workshop on how this approach has been used to integrate projections of land-use/land-cover change and terrestrial carbon dynamics across the state of California.

State-and-transition simulation modeling online course: June 12-13, 2018

This two-day course establishes the fundamentals attendees need to use the free ST-Sim software to develop spatially-explicit, integrated models of both landscape change and carbon dynamics. The course will be delivered interactively online with an option to follow the course in a group setting at the California Air Resources headquarters in Sacramento, California.

California land use and terrestrial carbon modeling workshop: June 14, 2018

This workshop focuses on how the U.S. Geological Survey has used the ST-Sim software to develop and apply the Land Use and Carbon Scenario Simulator (LUCAS) in California. The California Air Resources Board will host this workshop at their headquarters in Sacramento, California, with live-streaming available for those who are unable to attend in-person.

ST-Sim Training & User Group Meeting, November 28-30, 2017

Early registration is now open for the ST-Sim Training & User Group Meeting.

This meeting brings together current and future users of ST-Sim in order to learn more about the software and to share experiences regarding its application to a wide range of questions. The event begins with two days of training – including both introductory and advanced streams – followed by a third day of case study presentations by scientists demonstrating the latest ST-Sim tools and techniques. To close the event there will be a panel discussion regarding possible future directions for ST-Sim.

Audience: Scientists, managers and analysts from any and all land management agencies, including experienced, new and undecided users

Sponsor: The U.S. Geological Survey’s Invasive Species Science Branch

Location: Fort Collins Science Center, Fort Collins, Colorado

ST-Sim based study of California land use and water demand featured in Water Deeply

Water Deeply recently featured an article on a USGS and Nature Conservancy study using ST-Sim to account for potential land use impacts on water demand in California.  In the article, Tamara Wilson, the lead author of the study is interviewed and provides her perspective on the study implications for water management in California.
