The Hatfield Marine Science Center Research Seminar Series presents an online talk on restoration ecology.  David Thomson, a restoration specialist with the U.S. Fish and Wildlife Ecological Services, will speak on “Learning by Watching the Grass Grow—Lessons from a Decade of Applied Restoration Research.”  The seminar, free and open to all, takes place on Thursday, Feb. 4, at 3:30 p.m. 

The speaker’s description of his subject: 

“Ten years of preparing for and implementing projects made it abundantly clear, as each project was followed by the thought “I didn’t expect this result,” that Restoration Ecology is a very young science. The past decade started with simple questions like why are we only seeding grasses, entered some difficult territory trying to grow plants during a drought, and went off the rails a bit trying to downscale monitoring, partially in order to upscale acreages from tens to hundreds. Although restoration of herbaceous communities can take up to a decade to reach quasi-equilibrium (a state formerly known as climax) we did see clear signs of progress: we saw pioneer species perform well from seed, almost certainly reducing the ability of undesirable species to establish (aka direct competition); signs of succession, as perennial dominants expanded their range at the expense of said pioneer (mostly) annuals; natural recruitment of sown or planted species, the polite way to discuss reproduction; and more.”
