Dyke Marsh Wildlife Preserve:

Restoring a Primeval Wilderness in the D.C. Area

 

 

Thursday, April 10

7:30 - 9:00 pm

 

Green Spring Gardens

4603 Green Spring Road

Alexandria, VA  22312

703 642-5173

 

 VNPS programs are free and open to the public.  No reservations are necessary for   this presentation.

 

 

Naturalist Louis Halle called Dyke Marsh “the nearest thing to primeval wilderness in the immediate vicinity of the city.”  It is one of the last large tracts of freshwater tidal marsh along the Potomac River, and is one of the most biologically diverse habitats in the Washington, D.C. region.  The marsh is home to 300 known species of plants, 6,000 arthropods, 38 fish, 16 reptiles, 14 amphibians and over 270 species of birds.  It is the only site in the upper Potomac River zone with a breeding population of marsh wrens and has state-threatened breeding populations of least bitterns.  The state-threatened river bulrush is common in the marsh.

 

U.S. Geological Survey scientists have concluded that 1.5 to two acres of wetlands are vanishing every year, a rate so severe that Dyke Marsh will be gone in 10 to 20 years.  Dredging reduced what was once 200 acres of emergent marsh to 83 acres and destabilized the whole system, spurring the loss of another 23 acres.  Today fewer than 60 acres remain.  The National Park Service is proposing a restoration plan to stabilize and restore the marsh. 

Friends of Dyke Marsh President and VNPS member Glenda Booth will describe Dyke Marsh, its significance, the NPS restoration goals and the importance of wetlands and wetlands restoration.

Spring in the Potomac Gorge:

A field trip with Cris Fleming

 

Saturday, April 12

9:00 am to 1:00 pm

 

Turkey Run Park

George Washington National Parkway

McLean, VA

 

VNPS programs are free and open to the public.

Reservations are required for field trips.

 

 Join chapter Botany Chair Cris Fleming for a walk through one of our area’s best spring wildflower displays.  Famous for the spectacular show of Virginia bluebells along the Potomac River, Turkey Run Park also harbors other early spring flowers such as dwarf ginseng, swamp buttercup, wild geranium, sessile trillium, perfoliate bellwort and many others.  Participants need to be able to walk the zig-zag trail down the steep hillside and to cross the creek on rocks (there will be helping hands).  Depending on bloom status, we may see the very early bloomers like harbinger of spring.  The normal early bloomers may not yet be in full bloom.

 

Large oaks, beech, tuliptree, basswood, sugar maple and other mature trees form an exceptionally fine hardwood forest at Turkey Run.  A well-developed floodplain, rocky bluffs, and deep ravines are habitats of this 200 acre park.

 

Details and starting point for the walk will be sent to registered

participants.  Please RSVP to https://vnps20140412.eventbrite.com.  Space is limited.

The Potowmack and Prince William Chapters of the Virginia Native Plant Society invite you to the following event:

Early Spring Bud Break at Doves Landing

Field Trip with Carrie Blair

 

Saturday, March 29, 2014

1 pm to 4:00 pm

Manassas, Virginia

 

VNPS programs are free and open to the public, but registration for field trips is required due to limited space. Details and starting point for the walk will be sent to registered participants. We will be meeting at a nearby location and carpooling to the park.

Please RSVP to https://vnps20140329.eventbrite.com.

 

 

We will study trees and other woody plants, bud, leaf and flower development and any emerging native wildflowers from an upland forest down to a floodplain extending along the Occoquan River.  There will be a brief introduction with hand-outs of terms and illustrations in the parking lot before carpooling to the site.  Waterproof boots are recommended.  Binoculars, hand lens and walking stick for a stream crossing would be helpful.  We will plan for about 3 hours including the carpooling time, but may go over if there is interest.

Our Leader:

Carrie Blair has been a board member of Piedmont Chapter for 18 years and President for 5 years.  She has been studying trees for nearly 40 years, and has served as a Virginia Master Naturalist and a Front Royal/Warren County Tree Steward, since 2010.  She has volunteered as a docent at the State Arboretum of Virginia at the Blandy Experimental Farm in Boyce, Virginia for 20 years and has led hundreds of tree identification walks and classes.  Carrie has lived in the Marshall, Virginia area for 40 years and knows the land intimately by walking or riding horses.  Her home has five acres of gardens, a wildflower meadow and woods with over 100 species of trees and shrubs.

 

The Site:

Doves Landing is a new 235-acre Prince William County park located along the Occoquan River, extending a mile eastward from the confluence of Cedar Run and Broad Run upstream of Lake Jackson in Prince William County.  It provides access to a view of this beautiful river, and the gently sloping landscape and open forest comprise a moderate walk.  The site includes a one-mile buffer along the river and encompasses high quality wetland areas, significant floodplains and upland forests within the Occoquan Reservoir watershed.  The park has not yet been officially opened to the public pending a new entrance and parking lot.  In the meantime, the property has remained vacant, protecting the buffer along the river, which flows into the Occoquan Reservoir.  Doves Landing is centrally located in the county, one mile from the intersection of Prince William Parkway and Route 234.

In this lecture, Kevin Heffernan will speak on the established and new threats to our natural spaces from exotic grasses.  He will cover numerous invaders, with a focus on Virginia’s “New Monster”, Wavyleaf Basketgrass.  Early detection is critical to the control of these invasive destroyers, so come and learn to identify them and learn what to do if you discover them.

 

Kevin Heffernan is the Stewardship Biologist for the Natural Area Stewardship Division of Virginia DCR’s Natural Heritage Division.   The Natural Heritage Stewardship Section focuses on maintaining and enhancing the natural values of land areas and waterways to conserve biological diversity.  Kevin is a member of the US Forest Service’s Wavyleaf Basketgrass Task Force and is a recognized expert on invasive grasses.

Helen Hamilton: Grasses and Wildflowers of the Coastal Plain

posted Jan 11, 2014, 12:07 PM by Marty Nielsen   [ updated Jan 11, 2014, 12:08 PM ]

Helen Hamilton, naturalist, VNPS member and past President of the John Clayton Chapter will talk about Grasses in the Coastal Plain.

Ornamental native grasses furnish an attractive contrast to wildflowers and shrubs in the home garden.  With graceful plumes that wave in the wind, the stiff stems and leaves offer a backdrop for colorful plants, and remain standing for winter interest.  She will discuss the basics of grass identification, along with descriptions of species common to the Coastal Plain, and comments about their uses by the colonists and native Americans.

Her new book 'Grasses and Wildflowers of the Coastal Plain' will be available.
