Pardon Our Mud

Tuesday, May 26th, 2015

To add variety to the blog and to offer a fresh perspective from our visitors, we are inviting guest bloggers to write posts describing their visits and thoughts while at the reserve.  The guest blog is brought to you by Alison Rogerson, Program Manager for the DNREC’s Wetland Monitoring and Assessment Program.  Enjoy!

Pardon Our Mud

Spring time in an emergent tidal wetland marks a time nestled between frozen and barren, and lush with vegetation and buzzing with life.  It is during this window that we sprang into action and for three busy days installed a “living shoreline” beside the kayak ramp at the Blackbird Creek Reserve in Townsend.  But how did this come about and what does it mean?

A living shoreline is a technique used to either protect or restore a shoreline from forces such as erosion.  In this case, the shoreline on either side of the kayak ramp was shifting and washing away due, in part, to river currents going by.  To prevent further erosion and to protect the adjacent habitat the Delaware Department of Natural Resources and Environmental Control (DNREC) put in place a series of natural materials that will help to trap suspended sediments from the river water and encourage wetland plants.  These factors together will build and secure a healthy shoreline habitat that not only looks nice, but also protects the kayak ramp.

Living shorelines can be built from a variety of materials.  In this case we used “logs” of natural fiber casing stuffed with shredded coconut fibers, in addition to sand, dirt and wooden stakes. The logs are staked in to make sure that ice and waves don’t wash them away, and the matting underneath keeps the logs from sliding and sinking.   It’s messy, hard work for sure, you definitely want to have extra muscles on hand, but it is rewarding!  We had a strong crew out there and in three days we were able to install a cell on either side of the kayak ramp.  One cell already has a native wetland plant, Arrow arum (Peltandra virginica,) growing, and as mud begins to build inside the log cell the plants will slowly shift up with the new ground.  The cell on the other side of the ramp was empty so we trucked in clean sand and topped it with a little soil to give us a nice high base.  After things have a chance to settle in we will come back in June and plant native wetland species such as Spartina and more Peltandra.

Although it isn’t the prettiest to look at right now, just wait until this fall or next spring.  As plants start to fill in the site will begin to look less muddy.  In time it won’t even be noticeable, especially at high tide.  We hope this will be a great example for visitors to see and learn from.  Living shorelines offer a solution to preventing erosion, protecting shorelines, improving water quality, and providing habitat for fish and plants.   And because of all these rewards to the habitat DNREC encourages landowners to consider one for their shoreline needs.

The Reserve’s Changing Landscape

Tuesday, December 18th, 2012

Have you been to the Blackbird Creek Reserve lately?  You may have notice some changes to our farm field.  As part of our restoration plan for the Blackbird Creek Reserve, we have taken some agricultural land out of production and created/restored some freshwater wetlands.  Wetlands are areas where there are water loving (hydrophytic) plants, saturation of the land or free standing water during portions of the growing season, and hydric soils (soils that are wet enough during the growing season to develop low/no oxygen conditions).  Wetlands have many benefits such as absorbing water like a sponge which helps to reduce flooding, acting as a natural filter,  and providing important habitat for food, shelter, and nesting.  A couple of weeks ago staff and volunteers planted the wetland sites with various native water loving plants including rushes, wool grass, buttonbush, sedges, and pin oak.  Visit us on the web for more information about the Blackbird Creek Reserve, Delaware Wetlands, and Wetland and Waterway permitting in Delaware.

Learning from the River

Tuesday, July 31st, 2012

How better to learn about a watershed than to experience it? On July 12, 2012 teachers from several states participated in a watershed tour of the St. Jones River coordinated by the Reserve in collaboration with the Partnership for the Delaware Estuary (the Partnership).  The tour is one component of the Partnership’s annual watershed workshop for teachers.   The teachers explored the history, habitats, impacts, and the restoration efforts occurring in and along the St. Jones River in Kent County, Delaware.  At each stop along the tour teachers had the opportunity to interact with scientists, resource managers, and environmental educators about the importance of the St. Jones River; how it was impacted in the past; what impacts it today; and how it is being protected for tomorrow.   If you want to learn more about the St. Jones River visit the St. Jones Reserve south of the Dover Air Force Base in Dover, DE.

The Land Where Our Forefather Roamed

Monday, July 2nd, 2012

If you have ever visited the St. Jones Reserve you may know that we are neighbors of the John Dickinson Plantation.  At one time the St. Jones Reserve property was owned by the Dickinson family during the 18th century.   Mr. Dickinson was called the “Penman of the Revolution” because he was known for his Letters of a Pennsylvania Farmer to the Inhabitants of the British Colonies.  John was a politician but he identified himself as a farmer.   His cattle once grazed on salt meadow hay in the upper marsh surrounding the St. Jones River. He also saw the need to be a conservationist.  As he watched the trees in the area being depleted, he instituted a policy on his land where only dead tree material was to be utilized for building and repair. 

If you are looking for something to do this 4th of July week , visit the John Dickinson Plantation and the St. Jones Reserve to see the land where our forefather once roamed.  For more information about John Dickinson and the Plantation visit the John Dickinson Plantation on the web.  Please note that the Reserve and Plantation are closed on the 4th but opened other days of the week.

Opportunity to Make a Difference

Wednesday, March 21st, 2012

It is that time of year when the Reserve gears up for all things horseshoe crab related.   Every spring around May and June, the Delaware Bay beaches are covered with spawning horseshoe crabs.  During this time trained volunteers help assess the horseshoe crab population by participating in the horseshoe crab spawning survey.  The survey began in the 1990’s to assist scientists in monitoring changes in population of spawning horseshoe crabs in the Delaware Bay. Delaware’s well-trained and enthusiastic volunteers have made this program one of the most successful volunteer based wildlife surveys in the country.   As part of the bay-wide survey, the Reserve coordinates the volunteer efforts on three bay beaches (Kitts Hummock, Ted Harvey, and North Bowers).   The preparation for the survey begins in March by seeking volunteers who are interested in participating in research and are up for an adventure!

It is important that volunteers are trained for the survey as the data is being used in management and policy decisions.  The Reserve staff holds two volunteer training sessions in April each year for anyone interested in assisting with the Horseshoe Crab Spawning survey.   The trainings take place at the St. Jones Reserve, 818 Kitts Hummock Road, Dover.  You are only required to participate in one of the following trainings:

Thursday, April 5, 2012 from 6 – 7:30 p.m. at the St. Jones Reserve           

Saturday, April 14, 2012 from 10 – 11:30 a.m. at the St. Jones Reserve

Are you ready and up for this awesome opportunity to be a citizen scientist?  We hope so!  We could definitely use your help.  To register for a training or for more information visit us on the web.

Rescuing a Feathery Friend

Thursday, December 22nd, 2011

Many people living on the coasts and near oceans have heard of seabirds.  Some of these birds are what scientists call pelagic which means that they live mostly in the open sea or ocean; however, they will come to land to breed.  That is why it was such a surprise to see one of our researchers bring a juvenile northern gannet into the Reserve.  The northern gannet is a seabird known for their remarkable diving capabilities  to feed on various fish species.  These birds are primarily white with black wing tips, a yellowish head, and greyish eyes.  However, the one brought into the Reserve was a juvenile and therefore it was brownish with white spots.  This young gannet was found in a salt marsh near the Delaware Bay.  An unusual spot to find a gannet as it is a pelagic species; and it’s not breeding season.  Unfortuantely, the little gannet  might have a respiratory issue and was taken to Tri State Bird Rescue where it is being nurtured back to health.  For more information on northern gannets visit the US Fish and Wildlife Service website and for more information on bird rescue work visit the  Tri State Bird Rescue and Research website.

Scientist Log #4: Surprise Lurking in the Marsh

Friday, December 9th, 2011

Scientist Log: December 6, 2011

It’s always fun to find a nice surprise when I’m working in the field! While surveying impoundments at the Ted Harvey Wildlife Management Area from a Delaware Fish and Wildlife fanboat, one of the other scientists I was working with noticed some movement in the marsh. He asked, “Did you see that teal?” I replied, “No, I didn’t see anything?” Next thing I know he’s running through the flooded marsh after an injured teal  (so much for my great birding skills).  When he brought the green winged teal to me I noticed that half of its wing was missing. Luckily, the duck had found a great hiding spot where it was able to recover from its injury. Because its flying abilities were greatly hindered,  it was taken to Tri-State Bird Rescue where it will find a permanent home in captivity.  Another exciting field day!”

St. Jones Reserve Boardwalk Open and Ready for Visitors!

Wednesday, November 30th, 2011

The St. Jones Reserve Trail Boardwalk has a new look!  You may recall that the main boardwalk at the St. Jones Reserve was undergoing some renovations.  Those renovations are complete and the boardwalk is back open to visitors.  The new look includes wooden decking with more space between the deck planks and three sections of grating.  Both practices allow more sunlight to penetrate to the marsh surface.  The increased amount of sunlight reaching the marsh surface should decrease the amount of impact the boardwalk has on plant growth.  Come visit the Reserve and explore the marsh by taking a walk on the renovated boardwalk.  The trails are open 7 days a week from dawn until dusk.  Always be cautious of hunting seasons.  The best time to walk the entire trail is on a Sunday when there is no hunting.  For more information about the Reserve visit our website.

Thank you Wes!

Today we’re celebrating 12 years of outstanding service by the Reserve’s Conservationist, Wes Conley who is starting on a new adventure – retirement!  He’s been an invaluable resource to the Reserve and provided outstanding technical assistance and leadership in getting things done on the ground at the St Jones Reserve and Blackbird Creek Reserve.  His work ethic and dedication have brought great credit upon himself and the Delaware National Estuarine Research Reserve.  It has been amazing working with you Wes!


A Facelift for the Boardwalk

Friday, September 23rd, 2011

If you have been to the St. Jones Reserve recently you may have noticed that the boardwalk is being renovated.  This is exciting news as the Reserve will be a demonstration site for alternative decking material which allows more light to reach the marsh surface and will hopefully lead to more plants growing under the boardwalk.  In addition to alterantive decking, other areas of decking will be replaced with treated wood, but the spacing between the planks will be 1/2 to 3/4 of an inch which will also allow more light to penetrate to the marsh surface.  Because of the renovations, the St. Jones Reserve Trail will temporarily be closed until the project is complete for the safety of our visitors.  However, we encourage you to visit the trail after the project has been completed to experience the salt marsh from the renovated boardwalk.  We greatly appreciate your patience and look forward to your future visits.
