Topic: Learning by Watching the Grass Grow. Lessons from a decade of applied restoration research.
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, which I will cover in early February.
