Fall is a prime time for planting trees, and Delaware Nature Society has planted quite a few in the last three weeks. Planting trees in the fall can be the best time because the trees are going dormant for the winter and the ground is often very moist, which means when spring comes and the soil starts to warm, the trees will be ready to grow.

In the past several weeks, Delaware Nature Society has planted over 600 trees at three locations. On October 27 at Coverdale Farm Preserve, the planting of 12 enormous Red Oaks and Bicolor Oaks with 9 foot root balls and full canopies began. They were brought in one at a time by truck and are being placed in a section of field that is currently used for feed hay. This planting is part of Coverdale’s 10-year Master Plan. The field the trees were planted in will be turned into a grazing pasture that will house movable animal shelters. These trees were planted in a specific area in order to create a buffer for the Farm’s neighbors, and provide shade and forage for the livestock. All 12 of the trees have been put into the ground and other areas of the farm are designated for reforestation in the future. A big thank you goes to Hank Davis who not only funded the purchase of the trees, but hand selected the trees and is also funding their installation. Hank is a true champion of Coverdale Farm Preserve, and for that we are ever grateful.

Last weekend, two large tree planting events were held on Saturday morning. The first event took place at Middle Run Natural Area where approximately 150 volunteers helped to plant 400 trees. The tree planting is just one aspect of the biodiversity management project that Delaware Nature Society manages at Middle Run under contract with New Castle County. Jim White, DelNature’s Senior Fellow for Land Biodiversity Management, heads up the planting efforts each year. “We are working to increase the park’s forest habitat as well as to increase stream buffers next to Middle Run, which is a tributary of White Clay Creek,” says Jim. Increasing forest habitat provides food and shelter for a wide variety of native wildlife. Stream buffers slow down and filter pollutants and help to reduce erosion. Tree planting also has many other benefits, including making a positive impact on climate change. County Executive, Matthew Meyer also attended the event, lending a hand with the planting. Since 1991, thousands of volunteers have helped to plant about 55,000 trees at this New Castle County park, which is located near Paper Mill and Possum Park roads in Newark.

The second planting event last weekend was held at DuPont Environmental Education Center (DEEC). The Rotary Club of Wilmington planted 200 trees in the Russel Peterson Urban Wildlife Refuge with staff from the DNREC Division of Fish and Wildlife.  The project was funded by members of the Rotary Club who donated $2,000 for the trees along with funding from DNREC. The tree planting is part of an effort over the past 20 years to restore the freshwater tidal marsh with native plants to provide habitat for waterfowl, song birds, deer, raccoon, beaver, and even river otter. The Rotary Club of Wilmington planted the trees as part of a challenge to all Rotary Clubs across the globe. International Rotary President, Ian H.S. Riseley challenged every Rotary club to make a difference by planting one tree for each of its members between the start of the Rotary year on July 1, 2017 and Earth Day on April 22, 2018.

A sincere thank you to everyone who was a part of each of these events!

On an unseasonably warm Sunday in February I walked hand-in-hand with my 4-year old son along Wilmington’s riverwalk that parallels the magnificent Christina River. As we walked we passed by couples, families, runners, and people of all types with the musings of ice skaters in the background. My son and I talked about the ducks swimming by, the swift current carrying sticks and other debris and the “mean people” that littered their bottles and trash in the river. I couldn’t help but think that just a few years ago I would not have been able to share this experience with him. I am fortunate to share such an experience with him and I also feel fortunate that I understand the complexity and state of this river.

It is easy to see that the Christina River has undergone an urban renaissance resulting in the Chase Center, Tubman-Garrett Riverfront Park, Christina Riverwalk, a variety of restaurants, high-rise residential buildings, the Blue Rocks stadium, and the DuPont Environmental Education Center’s wildlife refuge. This growth is spurred by people’s desire to be near the water and the aesthetic qualities it provides, yet beyond this beauty there is a complex, natural system at work.

The headwaters of the Christina River lie within the state of Maryland and enter Delaware west of Newark. The White Clay, Red Clay, and Brandywine creeks are tributaries of the Christina River. The Christina River is freshwater yet tidal from just south of the town of Christiana to its confluence with the Delaware River at Wilmington. Extensive tidal freshwater wetlands, including Churchmans Marsh, exist along the lower Christina. The majority of the Christina River watershed is located in New Castle County (DE). The Christina River is a mostly urbanized watershed with over 50% of the land cover developed. The watershed is the site of the Port of Wilmington, an important shipping link, and one of the largest importers of orange juice, Chilean grapes, bananas, and automobiles nationally.

The Christina River has its share of historic contamination. There are numerous contaminated sites bordering the river. Samples have indicated that there are toxics present at elevated levels in the water bodies of the Christina River watershed and fish consumption advisories have been posted for the river. According to the USEPA’s water quality standards the Delaware portion of the Christina River requires varying levels of pollution reduction for nitrogen, phosphorus and bacteria.

Although the Christina River has fallen victim to years of industry, improper land use and anthropogenic influences the story of the river is a positive one. The state is working diligently to clean up and redevelop the toxic sites along the river. The Christina River is also demonstrating improving trends for many water quality parameters. According to a recent article on water quality trends in Delaware’s streams by Gerald Kauffman and Andrew Belden, water quality trend analysis for long term (1970/1980-2005) and short-term (1990-2005) trends show improvement in the Christina River for numerous water quality parameters including: dissolved oxygen (DO), total suspended sediment (TSS), total phosphorus (TP), and total Kjedahl nitrogen (TKN). Positive trends for these parameters indicate improving conditions in the river. Additional parameters, including bacteria, which levels have historically been increasing, show a leveling off for long-term and short-terms trends over this same time period, another good news story.

We know that the Christina River is not a pristine, natural river system yet research shows that there are positive signs for the health of the water body. The efforts by so many locally, state-wide and regionally to improve the water quality has had a positive impact. And as the riverfront becomes more popular and a destination in the region, it is my hope that individuals will learn more about the river and help protect this valuable resource through individual stewardship. And over the years as I continue to walk along the riverfront I will feel fortunate to be able to share this river, which inspires and motivates me, with so many people, especially my son.

Join us at DEEC on April 16 at 3:30pm for National Water Dance to celebrate the Christina River through dance performances and exploration of the marsh for the wildlife calling it home.

If you have never wondered about the process your drinking water goes through before it gets to your faucet, you are not alone. The Delaware Nature Society’s Wilmington Drinking Water Tour, led by Sally O’Byrne this week, provided the opportunity to discover where, when, and how your drinking water ends up in your glass. The City of Wilmington has used the Brandywine River as its primary drinking water source since 1827. Wilmington officials and Water Department employees quickly learned that water (treated and untreated) would have to be stored at various locations through the City. These locations include Cool Springs Reservoir, Rockford Tower, and Hoopes Reservoir.  Hold on to your mugs as we take you on a water drop’s journey from the Brandywine River to your teacup.

The Brandywine River is a major source of drinking water for Wilmington, Delaware.

As a drop of water, my journey began one day, when I was peacefully meandering down the Brandywine River. Suddenly, I was pulled from my path into a mill race that took me to the Brandywine Pumping Station, which is located in downtown Wilmington and is filled with three generations of pumping mechanisms. If I had traveled from the river in the early 1900’s, my transportation would have been provided by a 5-story, 1906 Holly Steam Engine (taken offline in 1968).  The modern pump I went through, however, was hardly larger than a fire hydrant.

Hoopes Reservoir is a raw water storage location for Wilmington drinking water.

From the pumping station, I traveled directly to Hoopes Reservoir where I waited to be treated.  I stayed there for several pleasant weeks.  When my time was called, and the people of Wilmington needed me, I was pumped yet again from Hoopes Reservoir to the Porter Filtration Plant, located near the Alapocas State Park in Wilmington.  Here, I went through several steps to ensure I was safe for drinking.

This raw water holding tank is where drinking water waits to be treated.

I waited patiently in the 36-million-gallon holding tank surrounded by the rest of the untreated, aka “raw” drops of water.  All of a sudden, I was pulled from my holding tank and travelled through a beautiful brick gatehouse and into green pipes where I began the “treatment” process. Ferric Chloride was used as a coagulant to help any dirt I traveled with to clump together.  I then enjoyed a ride in one of the six clariflocculators as I separated from the surrounding clumps of dirt.  I also received a complimentary treatment of lime to help bolster my ph and alkalinity levels.  The rocky part of the journey was when I traveled from the clariflocculators through a 12-step filtration and purification system full of stones, sand, and concrete. The end result ensured that I was polished and chemical free before heading through yet more pipes. Finally, I received a complimentary injection of chlorine and fluoride before heading to the “treated” holding tanks.  The tank I was sent to was Rockford Tower which provided the perfect view of Wilmington before gravity forced me into a nearby home where I quickly got boiled and poured into a cup of tea.  It was a very productive trip if I do say so myself! 

Rockford Tower is a location where treated, finished drinking water is stored. Gravity takes it to your faucet from there.

The Delaware Nature Society offers this trip and others with Sally O’Byrne, that educate our members about utilities, water, waste, and other necessary human industries every season.  This summer, the Conservation Action Force camp for 11-15 year olds will examine this water system as well as and other issues like air, water quality, large-scale composting, agriculture, biodiversity, and will tour Delaware’s Legislative Hall to report our findings.  If you know an 11-15 year old that might be interested, please register them for the camp at www.delawarenaturesociety.org.

Finally, my journey ended in a enjoyable and relaxing cup of tea.
