Cas manages the GIS database, provides GPS services/field data collection in support of Council projects/initiatives, and handles map production requests for Council staff and stakeholders. At times, he also masquerades as the Council’s graphic designer and web administrator.

His recent efforts are focused on developing the Council's WeedWatch Program. This program encapsulates our ongoing monitoring and outreach work as well as tracking other local, regional, and statewide efforts focused on the spread, control, and education of invasive plants. He manages three CDFA grants under this program that drive the compilation and development of a comprehensive invasive plant GIS database for the Los Angeles Region, a standardized Arundo dataset for Southern California, and an outreach campaign that will help support land managers and educate residents on local invasive plant issues.  

Some of his other recent projects include assisting in the development of the Tujunga Wash Watershed Management Plan, assembling a historic aerial photography database to facilitate the identification of historic wetlands along the San Gabriel River, and supporting the formation of a native seed bank database for the San Gabriel River.

Cas has a background in physical geography with an emphasis in cartography and visualization. He received his B.A. in Geography at the University of Illinois at Urbana-
Champaign in 1999. Previous to working at the Council, he was a Research Associate at the Geographic Modeling Systems Lab where he was involved in various GIS related projects tied to quality assurance/ quality control measures, historic aerial photo restoration, urban growth series mapping, watershed management, and 3D hydrologic modeling.

In his spare time, he resides on the board of the California Invasive Plant Council, participates in the Sierra Club, and is a long-standing member of NACIS and SCGIS. He digs tiki, mid-century design, and loud music. Aloha!
