Portia Halbert, Environmental Scientist

Portia Halbert is an environmental scientist for the Santa Cruz District of the California State Park system, overseeing an area of over 70,000 acres. She talks about the joy of wielding a drip torch for prescribed burns, about battling invasive species, about how the crumbs from your picnic lunch in the mountains can affect the survival of an endangered seabird, about her elaborate scheme to make Steller's jays sick to their stomach, and about her secret plan for using drones to blow up treetops.
