GIS ANALYSIS TO UNDERSTAND LANDSCAPE FUNCTIONAL CHANGES IN THE RIO SALADO SUBBASIN, NM

Project Motivations•Overarching Interests:• Understand landscape-scale changes through time• Natural evolution & redistribution of vegetative communities• Changes in hydrological parameters through time• Changes in geomorphological parameters through time• Contextualize trajectories of change in ecological parameters with respect to ecosystem function

•Understand how Rio Salado subbasin & La Jencia watershed have changed through time

Research Questions•Questions 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 Methods•Methods 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 Methods•Methods 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 History• La Jencia Creek is comprised of eight subwatersheds (12-unit HUCs)• La Jencia Creek Conservation Ranch’s missions:• Restore and protect the

ranch's native lands and wildlife • Provide educational and

partnership opportunities to those interested in conservation.

Term Project Intended Analyses• Types of Analyses:• NLCD 1992, 2001, 2006 from-to assessment of change in

classified land cover type through time • Variable source area assessment of wetlands of interest • WI assessment of Rio Salado subbasin and La Jencia watershed• Calculation of % impervious cover in region surrounding wetlands

of interest • Assessment of flow accumulation at water bodies/stream reaches

of interest and changes in this value through time • Assessment of hillslope slope- and aspect values for riparian

regions surrounding wetlands of interest • Assessment of changes in subbasin- and watershed water inputs

(precipitation) through time • Assessment of water contaminant loading, changes through time
