by Alexandra PermarGIS Analysis to understand landscape functional changes in the rio salado subbasin, NMProject MotivationsOverarching Interests:Understand landscape-scale changes through timeNatural evolution & redistribution of vegetative communitiesChanges in hydrological parameters through timeChanges in geomorphological parameters through timeContextualize trajectories of change in ecological parameters with respect to ecosystem function

Understand how Rio Salado subbasin & La Jencia watershed have changed through timeResearch QuestionsQuestions driving my current research interests include:What ecological parameters are useful for characterizing the function of an ecosystem?

Do GIS-, satellite remotely sensed, and field-based integrity assessment data properly inform conservation- and restoration site selection?Do the various data sources provide insight as to the current condition of ecological parameters?Do the data sources sufficiently inform assessment of ecological parameters at varying spatial- and temporal resolutions?Thesis Research MethodsMethods to address a portion of thesis objectives:Understand changes in ecological parameters through time Characterize landscape change through time using historical and contemporary data sets in two United States case studies (one in the Western U.S., another in the East).Derive and compare water budgets for case studies, addressing variables such as precipitation, evapotranspiration, consumptive water use, runoff, infiltration, and stored water.Analyze changes in vegetative community patterns through time (abundance, distribution, types, species). Evaluate changes in amounts- and types of urbanized infrastructure in case studies, and evaluate urbanization data in context of other data sets being used.

Thesis Research MethodsMethods to address a portion of thesis objectives:Understand changes in ecological parameters through time Where possible, contextualize case study changes with respect to natural landscape disturbances (including drought, fire, flooding) to ascertain what types and impacts disturbance have upon ecosystem function.Evaluate relative impacts of anthropogenic land use (grazing, recreation, restructuralization of water resources) on ecosystem function.Contextualize understanding of landscape changes through time with relevance to restoration site selection.Monitor restoration projects through time to observe how they enable the landscape to withstand disturbance.Life HistoryLa Jencia Creek is comprised of eight subwatersheds (12-unit HUCs)La Jencia Creek Conservation Ranchs missions:Restore and protect the ranch's native lands and wildlife Provide educational and partnership opportunities to those interested in conservation.
