This webinar was recorded on May 7, 2015. Sustainable management of natural resources under competing demands is challenging, particularly when faced with novel and uncertain future climatic conditions. Meeting this challenge requires the consideration of information about the effects of management, disturbance, land use, and climate change on ecosystems. State-and-transition simulation models (STSMs) provide a flexible framework for integrating landscape processes and comparing alternative management scenarios, but incorporating climate change is an active area of research. In this presentation, three researchers present work funded by Climate Science Centers across the country to incorporate climate projections...
State-and-transition models are increasingly being used to guide rangeland management. These models provide a relatively simple, management-oriented way to classify land condition (state) and to describe the factors that might cause a shift to another state (a transition). There are many formulations of state-and-transition models in the literature. The version we endorse does not adhere to any particular generalities about ecosystem dynamics, but it includes consideration of several kinds of dynamics and management response to them. In contrast to previous uses of state-and-transition models, we propose that models can, at present, be most effectively used to specify and qualitatively compare the relative benefits...
Recently,the United States Bureau of Reclamation agreed to increase springreleases from Upper Colorado River Basin reservoirs to create amore natural flow regime in the lower Gunnison River andUpper Colorado River. Fishery managers have expressed concern that newoperations could change reservoir conditions and jeopardize popular and economicallyimportant reservoir sport fisheries. This study attempts to predict howone aspect of reservoir conditions, thermal structure, might respond tonew dam operations at Blue Mesa Reservoir aimed at addressingdownstream ecological concerns. A one-dimensional thermal model (CE-THERM) is appliedto simulating thermal effects of ?traditional? and proposed ?new? damoperation scenarios....

Northern Arizona University will study how forest treatment practices and climate change may impact water balance across the Kaibab Plateau and critical habitats in lower elevations of the Grand Canyon. The project will include use of a forest landscape simulation model to examine how fuel treatments and prescribed burning will affect the resilience of forest ecosystems. The project will also address whether those activities would benefit the conservation of downstream riparian habitat by mitigating anticipated changes in the stream flow and water quality.The model will assist managers in developing, adaptation strategies for the conservation of riparian habitats by testing a range of realistic fuel treatment and...
