Pollinator meadow

Spring: bumblebees in penstemon

In an effort to create habitat for pollinators and ground nesting birds, Beardsley and Ridder decided to transform a 13-acre pasture planted primarily with non-native cool season grasses (mostly fescue), replacing them with native warm season grasses and flowers, all of which are more hospitable to grassland birds and pollinators. Working through the Environmental Quality Incentives Program (EQIP) of the US Department of Agriculture’s Natural Resources Conservation Service (NRCS) and following their recommendations, they began by treating the meadow with glyphosate in the fall of 2013 to eradicate existing non-native grasses. (More on glyphosate below.) A second spot spraying was applied in spring 2014, followed by seeding with about 15 species of forbs and 4 species of warm season grasses applied with a no-till drill. See the species list.

Then Nature took over. With the original fescue cover gone, the underlying seedbank was unlocked, and a number of species that were not seeded appeared along with those that were. Some of the plants in the seedbank were desirable (such as andropogon virginicus and purpletop tridens), some were not (autumn olive, coralberry, Japanese honeysuckle, multiflora rose, and mile-a-minute vine), and the jury is out on still others (wingstem and crownbeard, closely-related aggressive native plants that pollinators love and provide good structure for birds but shade out other plants; and blackberries, also aggressive but good cover for birds and forage for wildlife). The first summer, the meadow looked bad: the desirable plants that were seeded in the field were taking time to get established, and the undesirable plants were abundant.

At the recommendation of NRCS, the meadow was bushhogged in early 2015. Starting that year, it began to look better: coreopsis and daisies in the early spring; monarda, black-eyed susans, milkweed, and butterfly weed in the summer; ironweed and goldenrod in the autumn. A management program was established that, for the first few years, involved burning half the meadow each winter to control unwanted plants and eliminate the duff that might otherwise accumulate over the years and smother desirable plants. The other half of the field was left for winter forage and cover for wildlife. Observations made in the first few years suggested the meadow was doing what it was supposed to do: attracting birds and pollinators, providing forage and cover, and significantly increasing botanical biodiversity see the results of a 2015 survey of plant, pollinator, and bird diversity.

The meadow was the focus of an internet buzz when a rare species of bumblebee, bombus pensylvanicus, was detected, and a winter bird survey conducted by VWL director Amy Johnson revealed that it was having a significant positive impact on populations of overwintering birds, with substantially more individuals of more species detected in the pollinator meadow than in nearby fescue hay pastures.

Burning, arranged through the Virginia Department of Forestry, proved difficult to manage. There were few times when the crew and equipment were available when the meteorological conditions were also right—not too wet or too dry, or too much wind or snow cover. Moreover, the burning did not eliminate woody plants like autumn olive or coralberry, so some years, the meadow was both burned and bushhogged. Currently, it is generally managed by bushhogging half each winter. The plant composition varies somewhat from year to year, with some species trailing off and others remaining robust or increasing in quantity. Plant material is generally composed of about half species that were selected and half that were in the seed bank or introduced by wind, water, or animals. Given this outcome, Beardsley and Ridder wonder if it was worth spraying with glyphosate. Not only is it dangerous in itself, it is only effective if applied repeatedly over a period of several seasons before reseeding. They wonder if other methods of establishing these native grass and wildflower meadows might be developed that would produce equivalent or improved outcomes—tilling and drilling perhaps, or repeated mowing followed by drilling. They look to continuing research by VWL for potential answers.

Riparian Buffer

Beardsley and Ridder steward about a mile and a half of Rappahannock riverbank, some of it on both sides of the river. Much of the floodplain was cleared ages ago right to the river edge for cropland, chiefly for cattle corn production.

Field Work

Beardsley lives with his wife, Stephanie Ridder, on a farm in Rappahannock County, Virginia. Together, they have helped create a new organization, Virginia Working Landscapes, devoted to reconciling productive agriculture with biodiversity preservation and restoration.
