As Director of the Rocky Mountain Research Station, I am proud to be representing the excellent science produced here. In these 2019 Research Highlights you will get a flavor for the work of some of the scientists at our Station and how our work supports the mission of the Forest Service. These twenty selected highlights, and the top five Director’s Choices, were chosen because they were unique and relevant to current issues. In addition to the projects showcased below, RMRS has many more research projects located in the Station’s footprint and beyond. I invite you to browse our website to learn more about all of the science we have in progress to improve the condition of forests and grasslands across the country and around the world. For over a century, Forest Service R&D has been a research leader, delivering high-quality science with broad application. I am proud of RMRS’ contribution, along with our counterpart Stations, to the long legacy of Forest Service research.
