The Mid-Missouri Prescribed Burn Association in cooperation with SD NRCS and SDSU Extension hosted two eastern red cedar tree control workshops entitled “Grass or Cedar: Time to Choose” on March 3rd in Mitchell and March 5th in Yankton. The Yankton workshop was recorded. The workshop is split into six separate sessions and available on Youtube at: https://www.youtube.com/playlist?list=PLlldDb7IZYqIc80uMFNOSlJwKcQN87XoM. You will find an overview of the cedar tree encroachment problem in South Dakota along the James River and Missouri River valleys, a discussion of non-burning methods of control, an introduction to prescribed burning methods, and a discussion of technical assistance and available NRCS cost share programs.
Abstract: Fire created and maintains grassland ecosystems around the world, with the pattern and processes in these systems maintained by fire driven grazing – an ecological process called pyric herbivory. Pyric herbivory creates a patchwork of habitat types across space and time at local, regional, and continental scales, with each patch in a different state of post fire and grazing recovery. This diverse and shifting mosaic of habitat is what native wildlife in grassland ecosystems evolved with, and most wildlife species in these systems depend on more than one type of habitat to complete their life cycles.
Range management is like being a trial lawyer: you need all the evidence you can get to help you make decisions how your management and production objectives may need to change. State-and-transition simulation models are a general tool that can be used to forecast changes in vegetation across landscapes in diverse ecosystems. This webinar will give an overview of what state-and-transition simulation models are; describe the software tools available to develop and use them; and present case study applications specifically geared towards rangeland issues such as grazing rates, fire and invasive plants. The webinar was presented by Leonardo Frid of Apex Resource Management Solutions Ltd. (www.apexrms.com). Leonardo has been developing tools for ecological forecasting and training others to use them over the last 17 years. He has worked in various ecological settings from rangelands to forests across North America.
