Native groundcovers

/in , /by

Margaret Fisher, Plant NOVA Natives

Are you seeking a groundcover that is both beautiful and friendly to the ecosystem? Try looking beyond the old standbys to the new trend in gardening circles: native Virginia plants.

Bare ground in a garden is an invitation to weeds and erosion. The conventional landscaping solutions are either to pile on wood mulch or to plant an aggressive plant – such as English ivy, Japanese pachysandra, Vinca, spreading Liriope, or Yellow Archangel – then let it take over. The problem with those plants is that they take over more than just our gardens: they spread where they are not wanted by inexorably creeping along and by producing seeds that allow them to leap into our few remaining natural areas, where they crowd out the native plants and ruin the local ecosystem.

To prevent these unintended consequences, landscapers are now turning to plants that evolved locally, of which there are numerous examples that provide the “look” we are used to: a dense, low-growing monoculture for shade or part shade areas. Some are evergreen, others deciduous. A few have the additional feature of colorful spring flowers. Some can tolerate the bone-dry conditions under a tree; others prefer constant moisture. With the exception of Golden Ragwort (Packera aurea) and Common Violet (Viola sororia), none would be accused of being aggressive. Isn’t it nicer to have a beautiful groundcover that supports the ecosystem than to have a bare mulch garden? Details and photos can be found on the Plant NOVA Natives website.

National Wildlife Federation
11100 Wildlife Center Drive, Reston, VA 20190
Thursday, 9 May 2019
7-9 pm

Join the Audubon Society of Northern Virginia (ASNV) for a FREE workshop to prepare for the longest running annual spring bird count in this area. The class will include an overview of WMBD, the Lower Potomac River Important Bird Area (LPR-IBA), key species, and techniques (eBird) used to count them. You’ll also learn how the data is used. Follow up what you’ve learned in the classroom by participating in the count on Saturday, May 11 with Jim Waggener.

Instructor: Larry Meade. Larry is President of the Northern Virginia Bird Club, and a former Board member of the Virginia Society of Ornithology. He has served as a Sector Leader for a number of years for several of our local Christmas Bird Counts and is an avid nature photographer (http://uberlarry.smugmug.com/).

Help develop a feasibility study for community choice renewable energy options

/in , , /by

The goal of this Thriving Earth Exchange project is to carry out a feasibility study for the creation of a Community Choice Aggregation (CCA) program to provide options for the residents and businesses of Arlington, outside the incumbent electric utility, to choose their rate plans and energy sources. Arlington was chosen due to its transformative Community Energy Plan, though Arlington is not an official partner of this effort. This project will be accomplished through a study on CCA options to explore how Arlington could procure, generate and competitively fund renewable energy projects and inform policymakers and ratepayers of opportunities for renewable energy generation. The options to use of solar photovoltaic (PV) and solar thermal energy in buildings has become increasingly cost-effective over time and aids in energy resilience to peak load events at the macro level when coupled with advanced energy storage. This project will align with Arlington County’s commitment to climate action and stand in accordance with the goals outlined in the Paris Agreement, and may serve as a demonstration model for similarly-urbanized communities or those with comparable energy use patterns and volumes.

The team will work in hand with Virginia Clean Energy led by local residents Silvia Zinetti and Morris Meyer. Virginia Clean Energy is a new nonprofit fiscally sponsored by LEAN Energy US, a 501 (c)(3) organization based in California.

Silvia and Morris seek a scientific partner to help Virginia Clean Energy with:

  • data analysis, visualization, and interpretation for the implementation of a technical study to incorporate renewable energy into the electricity market with a CCA.
  • resulting price structures and GHG reduction scenarios of various energy combinations.
  • Preparation and development of the findings for local conferences and County board meetings.

The community is looking forward to working with an energy engineer or energy economist and enthusiastic graduate student assistants with an interdisciplinary mindset.

Sea Level Rise, Its Impact on the Potomac River Shoreline Ecosystems, May 15th

/in , /by

Norma Hoffman Visitor Center, Huntley Meadows Park
3701 Lockheed Blvd., Alexandria Virginia 22306
Wednesday, 15 May 2019
7:30 pm
FODM will host an informal social gathering at 7:00 p.m. before the event.

Join the Friends of Dyke Marsh to hear Geoffrey Sanders, a National Park Service (NPS) biologist, give a presentation on the impact of sea level rise on Dyke Marsh and other shoreline communities based on modeling of several scenarios. His study concluded that “significant habitat changes are likely at Dyke Marsh as a result of rising water levels,” including changes in vegetation.

From 1900 to 2017, sea levels rose about a foot and a half along the Chesapeake Bay, according to scientists at the Woods Hole Oceanographic Institution. An Old Dominion University study, “Climate Change, Global Warming and Ocean Levels,” assumes a mid-range estimate of a 3.7-foot increase in sea level rise by 2100. Former Governor Tim Kaine’s Commission on Climate Change in 2008 predicted that sea levels in the Chesapeake Bay region will be 2.3 to 5.2 feet higher by 2100.

The program is sponsored by the Friends of Dyke Marsh and cosponsored by the Environmental Council of Alexandria, the Northern Virginia Conservation Trust, the Four Mile Run Conservatory Foundation, and the Potomac Riverkeeper Network.

Help stop the spread of a new species of Water Chestnut

/in /by

Localities, pond management personnel and the general public are asked to look for a new species of Water Chestnut (genus Trapa) recently found in the Potomac Watershed. It has been spreading since 1995 so you may have already encountered this floating aquatic vegetation growing over the surface of a pond, lake or other fresh waterbody. This species is identified by the seed cases having two spines instead of four found in the Eurasian Water Chestnut. Reports of this or other invasive aquatic species can be made via a free phone app. Water Chestnut (an annual) will sprout in May 2019, spread over the water surface and then flower and fruit by July, it drops seeds all season until it senesces after a hard frost. To stop the spread, management, by harvesting the plants by mid –July, is very successful in eradicating the plants but it may take several years of effort, if some seeds lay dormant.

Rain barrels purchased from retail sources can be expensive. As part of a regional initiative, Northern Virginia Soil and Water Conservation District offers build-your-own rain barrel workshops and distributes low-cost rain barrels to Fairfax County citizens. You will learn how to install and maintain a rain barrel and take one home! By installing a rain barrel at your home you will provide your plants with water they will love, save money and water, and protect the Chesapeake Bay! The workshop fee is $55, which includes the rain barrel for you to take home. Learn more about the program and register to attend a workshop.
