Phragmites Tankwa?!?!

HarborLAB will commence its multicultural boatbuilding program in March with the International High School! We’re thrilled to serve these students, who are in an intensive college preparatory program for immigrant youth with limited English. IHS is housed within CUNY LaGuardia Community College.

We’ll make reed craft using invasive phragmites, which crowd out many of region’s indigenous estuary species. We’ll start with a demonstration inspired by the tankwa, an Ethiopian work boat made from papyrus on Lake Tana. Other models will follow, launching on June 8 for United Nations World Oceans Day. Our goal is for these boats to greet the arriving Hokule’a, a Hawaiian canoe circling the globe for environmental education. This is easily achievable at Gantry Plaza State Park, if permitted, directly facing the UN and a few minutes paddle from our launch.

We welcome volunteers to join the effort and donors to sponsor us!

Grass (family: Poaceae) and sedge (family: Cyperaceae) boats are among the most ubiquitous types because papyrus, bamboo, and reeds are renewable and readily available to those working the water as fishers, ferryers, and traders. Grasses and sedges also wonderfully pliable materials, providing both planking and twine. We’ll work with the United Nations community and immigrant cultural centers to maximize our inclusive service and multicultural representation.

This world heritage is truly ancient, as evidenced by petroglyphs depicting reed boats in Azerbaijan that date back 12,000 years. These boats quickly return to the soil, so archaeological evidence is spotty. Logic would indicate African origins. The earliest remains of a reed boat are 7,000 years old, unearthed in Kuwait. Palm fronds are also used in a similar fashion in the Persian Gulf. Even the story of Moses begins with him set afloat in a bulrush ark. The apexes of accomplishment in this art include ancient Egyptian papyrus voyaging vessels and the ornate craft of the living Uros culture of Lake Titicaca on the border of Peru and Bolivia. Our most famous reed heritage boat in North America is the tule (pronounced too-lee). Watch one get built in the video below!

On the East Coast, science writer and ecologist David Samuel Johnson proved the viability of phragmites boat construction. Even young students can build these boats.

Benefits of this project:
  • Environmental science education: Indigenous/invasive species, rhizomes, ecological services, estuaries, wetlands, etc.
  • Cultural and Economic Education: World heritages, commonalities and differences, economic development and identity, renewable resources and growth, etc.
  • Habitat Restoration: Tangible results from removing invasive reeds (and removing seeds before construction). New, native plantings would bring even more value.
  • Safety: No power tools are needed. Adults would maintain a good ratio and oversight of youth. All paddling would be done under HarborLAB insurance with Red Cross certified (Water Rescue, CPR, AED, First Aid, adult/pediatric) volunteers in safe areas. HarborLAB will provide safety support from sit-on-top kayaks, though these reed boats will be much more seaworthy.
  • Youth empowerment: Students will do much of the building, paddling, documentation, and outreach themselves.
  • Publicity: We’ll paddle these boats past the UN and skyline, generating great images and video. This would be a sight never seen on the East River. This is especially true if we are able to support the Hokule’a effort.
  • Budget: The materials are harvested invasive plants and twine.
  • Sustainability: The boats will last a season and then be composted to enrich planting areas for habitat or ornament (not edible gardens).
  • Outreach: The students, educators, organizations, agencies, and companies involved will trumpet this unique project, delivering some aspect of its value to wider audiences. The boats will be brought to communities throughout NYC.
  • Long-term Results: Thorough documentation will allow other educators to reproduce our results and build upon them. The excitement may seed the founding of a World Boatbuilding Museum (a place where the public can see small boats from around the world — reed, skin-and-frame, wood, and more) built before their eyes, and ride aboard them) that could be a major tourist draw.

If you’d like to volunteer with us and the students, please email volunteer@harborlab.org with the subject line “Boat Building.” To sponsor, please email support@harborlab.org.

A CHOCOLATE VALENTINE TO THE NEWTOWN CREEK

HarborLAB and MAST Brothers’ “Cocoa Coast” Brings Habitat to Superfund Waterway

 

When: Wednesday, February 10: 2:25PM-2:55PM

Where: 53-21 Vernon Boulevard, LIC, NY 11101

 

Reporters are also welcome to join HarborLAB volunteers as they pick up hundreds of pounds of cocoa husks from two MAST Brothers factories. Typically Wednesday and Sundays, 3PM-5:30PM.

Event:

HarborLAB and MAST Brothers Chocolate Makers have partnered for the past two years to turn tons of deliciously fragrant cocoa husks from the company’s bean-to-bar factories in Brooklyn into clean, fertile soil on the Long Island City waterfront of the Newtown Creek. This growing shoreline slope and berm at HarborLAB’s canoe and kayak launch is now home to an expanding habitat of native flowers and fruits for butterflies and birds. Chocolatey love for a long-unloved creek!

 

“We’re excited to rescue organic material from landfill to create a beautiful, clean landscape of native flowers and orchards in a place that needs love, on Valentine’s Day and every day,” said Erik Baard, founder of HarborLAB. “Our volunteers are grateful to MAST Brothers and to Queens Community Board 2 Environmental Chair Dorothy Morehead for building this offbeat, fun, and useful relationship.”

Check with organizers for updates regarding public officials who might speak.  

Photo opportunities each Wednesday and Sunday (including Valentine’s Day):

  • Students and volunteers spreading cocoa shells and burlap bags on the waterfront.
  • Bag stamps: Madagascar, Tanzania, Peru, Venezuela, Papua New Guinea.
  • HarborLAB waterfront and Manhattan skyline from Pulaski Bridge.

DETAILS:

The Newtown Creek is a place New Yorkers usually associate with the smells of sewage, petroleum spills, and the sulfuric gases of anaerobic bacteria. The MAST Brothers’ husks, along with other plant matter, compost into rich and healthy soil in an area deprived of it. And for a time the place smells delicious!

Our soil creation technique is commonly known as “lasagna composting,” in which alternating layers of carbon and nitrogen-rich materials interact. The husks cover volunteers’ kitchen scraps, tea bags, etc. Cocoa husks have a desirable 3:1:3 fertilizer ratio of Nitrogen: Phosphorous: Potassium. Burlap bags are made from jute plants, a type of mallow. With a small amount of additional soil and beneficial invertebrates and bacteria, a rich humus forms. Broken bricks rescued from landfill form a substrate mimicking our region’s glacially transported rock.

The New York State Department of Environmental Conservation encourages natural shoreline stabilization that relies on root systems instead of always building bulkheads. Growing at HarborLAB’s kayak and canoe “GreenLaunch”: Milkweed (on which Monarch butterflies depend), goldenrod, pokeberry, serviceberry, American persimmon, beach plum, hackberry, fig trees, Kazakh and other apples, Asian pears. The native seeds were gathered by HarborLAB volunteers, CUNY and NYC Public School students, and provided by the NYC Department of Parks and Recreation’s Greenbelt Native Plant Center. Trees provided by New York Restoration Project, US Department of Agriculture, and Cornell University. Coming soon: fruiting vines and native spartina saltmarsh grass (for the intertidal zone).

About HarborLAB:  Student and volunteer-run HarborLAB operates from a 125’ shoreline in Hunters Point outside the Circus Warehouse, a school for big tent performance arts, thanks to Schuman Properties. HarborLAB volunteers serve communities throughout the Hudson River estuary and watershed with free environmental education programs.

2015 Gantry Plaza State Park Water Quality

2015 Citizen Water Quality Testing Program Report

by Josue Silvestre, Engineer in Training
HarborLAB Water Quality Sampling Coordinator

HarborLAB takes part in the Citizen Water Quality Testing Program (CWQTP), an initiative of the New York City Water Trail Association that coordinates weekly grassroots monitoring of metropolitan area waterways for a 20-week period from May through October. I had the opportunity to lead HarborLAB’s participation in 2015. Our focus was again Gantry Plaza State Park, where we serve cumulatively thousands of children, teens, and adults through public paddling programs and special partnerships with organizations serving disadvantaged youth.

We received training from The River Project and a research team at Columbia University’s Earth Institute on water sampling at docks and shorelines. The sampling season launched on May 28 with 38 sites from Yonkers to Jamaica Bay. We measured nitrate and phosphate with in-situ testing kits and brought chilled samples rapidly to five labs to test for Enterococcus, a gut bacterium indicative of sewage. While nitrate and phosphate levels are immediately registered, bacteria must be incubated for more than 24 hours.

Gantry Plaza State Park is on the East River, a tidal strait within the Hudson River Estuary. The CWQTP concerns itself with wastewater contamination of the East River due to past and recurring contamination from combined sewer outfalls (CSO) and malfunctioning of wastewater treatment facilities. Paddling groups and nonprofit littoral ecology experts assert that because NYC Department of Environmental Protection surveys sample in deeper water, official statistics don’t account for bacterial colonies near shore, where human contact and wildlife activity is greatest. NYC Department of Health water testing focuses on swimming beaches, not kayak and canoe launches.

HarborLAB cancels programming at Gantry Plaza State Park on days following significant rain as a precaution against CSO contamination.

Enterococcus levels are presented as a Most Probable Number (MPN), or the number of colonies per 100 ml of water counted after incubation. These numbers set thresholds for recommending public notifications or temporary closures. New York City Department of Health Enterococcus standards for swimming are as follows:

MPN <35 = acceptable for swimming

MPN between 35 and 104 = unacceptable if level persist

MPN >104 = unacceptable for swimming

Throughout the 2015 CWQTP season (see figure 1) lab results showed that the presence of Enterococcus at Gantry Plaza State Park usually measured within acceptable conditions for swimming. It was observed that on three occasions Enterococcus levels at the site were unacceptable for swimming. Similar results were obtained in the previous 2014 CWQTP season (see figure 2) with one measurement exceeding the limit acceptable for swimming.

These spikes might correlate to rainfall prior to measurement (with one of the three a possibly anomalous result), as seen in figure 3, provided by the Riverkeeper organization through the citizen testing data web tool hosted on its website. That is, a wetter season in 2015 may be the cause for having have three peaks in Enterococcus counts compared to one peak in 2014. The amount of rainfall in the 2014 season, from May 22 to October 02, was 14.76 inches, according to the National Weather Service Forecast Office. That was 1.59 inches less than the 2015 season’s 16.35 inches for a same period (May 21-October 01).

Nitrate (NO3) and Phosphate (PO4) in-situ testing was new to the 2015 season. Nitrates and phosphates from urban runoff can cause eutrophication, a process that depletes lakes, streams, and rivers of oxygen. The procedure for in-situ testing was straight forward. The test kit consisted of two small tubes with nitrate and phosphate reactors and a small cube (see figure 4). Each tube would absorb water from a small cube of the sampled water. The tubes would change color after a few minutes indicating the level of NO3 or PO4 respectively. Throughout the season, low concentrations of Nitrate and Phosphate testing were recorded and these remained constant.

For me, as an international student with an engineering background in water resources, and an advocate of sustainable water management, constant monitoring of water bodies is of utmost relevance. It informs environmental regulators whether the water body supports a healthy aquatic ecosystem. While participating with HarborLAB collecting water samples, I came to appreciate the importance of keeping New York City’s waterways pollutant free. It helps revitalize shores once plentiful with aquatic life and maintain a balance in the ecosystem. In addition to revitalizing shores, effectively protecting our water bodies from pollutants creates an increased public interest in recreational water activities.
