Delaware is a state of “small wonders” with lots to see, do, learn and enjoy!  Becoming a Certified Delaware Master Naturalist volunteer is an exciting way to explore our beautiful state and to help preserve its environmental wealth.  The idea of a Delaware Master Naturalist Program took shape in Fall of 2018. In Spring of 2019, under the collaborative direction of University of Delaware Cooperative Extension, the Delaware Nature Society and guided by a State Steering Committee, the program’s framework was created. By spring, 2020, the pilot Master Naturalist volunteer training program will be conducted by Delaware Nature Society at the Ashland Nature Center!

What is an LOP?

A Local Organizing Partner (LOP) is an environmental organization (nonprofit, government, etc) that agrees to provide volunteer opportunities for Delaware Master Naturalists. The LOP works closely with trained Master Naturalists to coordinate and execute Master Naturalist volunteer projects, recruit volunteers into the program, and work with other organizations to maximize the Delaware Master Naturalist mission. 

There is no cost to register as a LOP. Once accepted to the program, LOPs will receive a Local Organizing Partner Resource Manual.

Program Benefits

There are many benefits to becoming an LOP, including access to trained volunteers that can help accomplish and expand your mission. These volunteers can lead efforts, initiate service projects, gather research data and recruit additional volunteers, all while requiring limited supervision. 
 

As an LOP, you can...

• receive support from the statewide program;
• advertise volunteer opportunities on Delaware Master Naturalist website;
• reach a wider group of stakeholders through the DMN Network;
• gain access to volunteer management system to track volunteer hours (easy to use and extract data from); and
• connect with interested individuals via the State Program Coordinator.

• Farnhurst Potter's Field 
  • Contact: Faith B. Kuehn, DHSS,  Faith.Kuehn@delaware.gov
  • Location: Just west of Baylor Blvd., on State of Delaware’s Herman Holloway Campus, New Castle, DE: 39.6977700, -75.5810700. DHSS property with DRBA rights of way. 
  • Volunteer Opportunities: Keeping the area around the markers clear of weeds and vines, and covered with layer of wood mulch. Installing a native plant garden near the cemetery entrance and providing signage. Developing the biological history of the area and impact of industrialization.
  • Background: The cemetery operated from 1884-1933. Plans for I95 construction included covering the Potter’s Field with a 20ft. embankment, to construct the FAI1 interchange, connecting to I295 and the Delaware Memorial Bridge. A newspaper request for relatives of those buried in the Potter’s Field received no replies. Construction proceeded. A 1958 Wilmington Morning News article stated that “the State Highway Department does not intend to be ruthless about the old Potter’s Field.” It would erect a marker describing the Potter’s Field and the number of people buried there. However, no marker was ever installed. For nearly 50 years, the site was neglected and nearly forgotten. Over time, construction debris and trash accumulated. Trees, bushes and vines grew and entangled, covering up the graves not covered by the interstate. The only hint of the cemetery was an exterior chain link fence. In early 2019, the cemetery was cleared of several trees, along with long-accumulated trash and many invasive plants, shrubs and vines. Some new fencing was installed, a parking lot and a few signs. NCC Historical Marker #254 was dedicated on November 1, 2020.
    The marker reads: “The Farnhurst Potter’s Field – New Castle County Hospital operated at Farnhurst from 1884-1933 and provided shelter, food and medical care to the needy. The more than 2300 burials here include individuals from these facilities and the indigent, unclaimed coroner’s cases, and stillborn babies. Numbered markers identified the graves. The Cemetery was abandoned in 1933. Construction of I-295 in 1958 led to an embankment built over nearly 85 percent of the graves. Many burial records were lost, but most of those identified were African American men. Several Civil War veterans were also buried here. This marker honors their lives and final resting place.” Following the Historical Marker dedication, a plan was developed to restore this Potter’s Field. The plan’s primary goals are to manage invasive plants, keep grave markers visible, and establish a native plant buffer zone along the road edge to simplify ongoing maintenance. The total area is about ½ - ¾ acre in size. In January 2021, this project received a Small Grant from DISC (Delaware Invasive Species Council) to purchase herbicide and wildflower seeds. Aggressive weed management (spring and fall herbicide application along with weekly trimming) was needed to keep the markers free of vines and other vegetation and prepare for fall planting of the native seed mix. The section with markers will be covered with bark mulch. A wildflower buffer will acknowledge the rich history of this area, and restore the cemetery as a living monument using native plants. Future plans also include additional signage at the site, and creating a space for seating and reflection. Two Master Naturalist Trainees have been helping with this work, and are keeping a project page on iNaturalist.
    Following up on a report statement that during the construction of I95 the Christina River had been diverted from Farnhurst, and additional aspect of this project is being developed. Historic maps show a large loop in the Christina River at Farnhurst (approx. 1-2 square mile area). The area was historically known as McCrone's Swamp. Rather than build 2 bridges during I95 construction, the Highway Department diverted the Christina River and filled in the river’s huge loop. Through online records of herbarium specimens (Mid Atlantic Herbaria and the Academy of Natural Sciences’ IDigBio, Integrated Digitized Biocollections), a list of historical plant records collected prior to Interstate construction is being developed. The disregard for the people buried in the Farnhurst Potter’s Field is mirrored by a disregard for this historic and once biodiversity-rich area.

  • About: Founded in 1989, the Kalmar Nyckel Foundation (KNF) is a non-profit educational organization that built, owns, and operates Kalmar Nyckel, the Tall Ship of Delaware as a cultural and maritime heritage resource. The ship and foundation serve as catalysts for educational and community development in Delaware and beyond. The Tatiana and Gerret Copeland Maritime Center and shipyard campus are located on Wilmington’s East 7th Street Peninsula, just 200 yards from “The Rocks,” the landing site of the original Kalmar Nyckel in 1638.
    This site is the ship’s homeport as well. When the Copeland Maritime Center was built in 2014, the Foundation created and planted beds and two bioswales with native plants. We would be very excited to have one or two master naturalists as part of our team in 2022.

  • Volunteer Service Activities for Delaware Master Naturalists: Stewardship (Restoration of Property), Citizen Science Program (Plant Surveys), and Engagement (Participate in events working with the community).
  • About: The Trustees of The New Castle Common is a non-profit organization incorporated in 1764 and reincorporated by the Delaware Assembly in 1792. Its purpose is to preserve and protect the historic Common lands for the use and benefit of the inhabitants of the town of New Castle. Income is derived primarily from property rentals and investments.
    
    The Trustees own about 640 acres, including a farm (100 acres), riverfront parks, meadows and buffer areas around residential areas, shopping centers and a 250 acre area of marsh and forest north of town. The Hermitage Natural Area (100 acres) within this latter area is the primary location where Delaware Master Naturalist will work. This area contains a large lightly managed 2nd growth forest (last farmed c1950), a large marsh area (currently used only for observation, study and great birdwatching) and a native grass/wildflower meadow under active restoration by invasive removal and native plant replanting.
    
    The Trustees are looking for prospective Delaware Master Naturalists who are interested in helping with restoration and removal of invasive aliens. The current focus will be with engagement with the community, continued restoration on the meadow and woods, and citizen science program. In the off-season Delaware Master Naturalists would work on cutting vines, identifying and tagging desirable plants in the forest and overgrown areas, refreshing nature trails, and engaging in events relating to community involvement, such as Volunteer Days and Nature Walks.
