Professor Mark Sytsma directs the Center for Lakes and Reservoirs at Portland State University, where Oregon's first comprehensive program for managing "aquatic invasive species" is underway. Introduced plant and animal culprits, like the mitten crab, can clog screens and block flow in the irrigation canals that are critical for crop production. So Mark is working with a team of state and federal agencies, industry partners, and students, to keep an expert eye on them and protect the bounty of our entire region.
