The combined effects of agriculture, climate change, and river channelization have left native Northern New Mexico species vulnerable to predation and competition from invasive species. This study examines the demographic changes of the native Northern leopard frogs after the removal of the invasive species the American Bullfrog. A section of the Mora River was divided in 2000- meter long section. One control region where no bullfrogs were eliminated and an experimental region where we eradicated Bullfrogs. Fifty one Leopard frogs were captured, pit tagged, and processed for demographic data. Control and experimental regions did not differ in the relative abundance of leopard frogs. We did not find significant difference in the mass of frogs from the two regions either. The preliminary data does show lower average mass and greater abundance in the experimental region suggesting an increase in recruitment of metamorphosis frog into the population. A change in demography within a year of bullfrog removal shows how fast a species can react to environmental changes.

This webinar by Dr. Linda Nagel discusses the adaptive silvicultural planning process to guide forest managers through the process of incorporating climate change into natural resource management. Case studies and a science-management partnership will be highlighted.
