In this 2014 poster, Ryan and Harris report preliminary results on a study of evapotranspiration (ET) at the Cibola National wildlife Refuge. They ask whether groundwater responds to a massive change in ET of surface vegetation and assess baseline well and evapotranspiration data as a proxy for the anticipated tamarisk beetle migration.
