Cimarron River Watershed NLCD 2011 NASS CDL 2011 Cimarron: 49,379 km 2 Cimarron (OK):18,240 km 2 1950-2011: 6, 000 km 2 cropland lost to grass, range and urban areas Since 1999: grassland encroached by woody plants (red cedar) Reduced streamflow (Zou et al. 2015) 3
Cimarron River Watershed Lower Cimarron Eagle Chief Wetland Area: 132 km 2 Ecological Portfolio & Wetlands 8 Level IV ecoregions 3 Level III ecoregions 1000s of depressional wetlands The Nature Conservancy priority area 4,913 km 2 (26.9% of the CRW) Area: 717 km 2 Lower Cimarron Skeleton Wetland Area: 155 km 2 Lower Cimarron Wetland Area: 155 km 2 4
Cimarron River Watershed Research Question How do extreme climate events affect the vulnerability of socio-ecological systems in the Cimarron River Watershed? 5
ENVISION Agent-based modeling platform Spatially and temporally distributed Incorporates physical, bio-physical, social models Compare future scenarios based on stakeholder interests Developed by Dr. John Bolte and his team at the Oregon State University http://envision.bioe.orst.edu Applications (Oregon, Ontario, Idaho) Interaction between aquatic ecosystems and land development Climate change impacts on economically valuable forests Urban and suburban landscape planning Impact of growth (economic & population) & climate change on water availability 6
ENVISION Application Development Goals (Economic Services, Ecosystem Services, Sociocultural Services) Provide a common frame of reference for actors, policies and landscape productions Landscapes http://envision.bioe.orst.edu/ 7
