What Green Roofs Can Do for NYC’s Environment and People

First-ever forum on June 7 brings together city researchers, educators, and policymakers to explore the potential of green roofs for the City and ways to unlock it

 

New York, NY, May 17, 2018. The NYC Green Roof Researchers Alliance will hold its first annual conference, “The State of Green Roofs in New York City,” to discuss cutting-edge research on urban green roofs on Thursday, June 7, at The New School. This is the first-ever forum on the emerging fields of green roof science, policy, and education.

Coordinated by NYC Audubon with funding from The New York Community Trust, the NYC Green Roof Researchers Alliance is a consortium of over 50 researchers, educators, and policymakers from 17 New York City and State institutions. It is investigating the potential benefits of green roofs, developing a comprehensive overview of green roofs in New York City, and working to expand them across the cityscape.

 

New York City’s one million rooftops add up to a vast underutilized landscape that could be harnessed to make a more resilient and equitable urban environment. If effectively designed and sited, green roofs can soak up stormwater to reduce sewage overflows that pollute the city’s waterways, filter air pollution, moderate extreme heat, decrease carbon emissions, and create habitat for wild birds, bats, and pollinators.

 

The conference will open with a keynote by Alan Steel, CEO and President of the Jacob K. Javits Convention Center, which installed the largest and most studied green roof in the city (and one of the largest in the country) when the center was renovated in 2013. Topics to be covered at the conference include the development of a map and database of New York City green roofs, the use of green roofs by birds, bats, and insects, and the effects of green roofs on stormwater retention, energy use, and the urban heat island effect. Presenters will give an overview of policies that have expanded the use of green roofs in other cities and the ways in which New York City educators are using green roofs for science instruction.

Tribute in Light Monitoring 2017

Every year on September 11, two beams of light illuminate the sky over Manhattan, reminding New Yorkers and the nation to pause in remembrance of those who lost their lives on 9/11/2001. New York City Audubon has monitored this important and touching tribute since 2002 to ensure it is safe for migrating birds. The beams, created using 88 7,000-watt xenon spotlight bulbs, can attract large numbers of night-migrating birds in some years. Once in the powerful beams the birds can become “trapped” and circle the lights, putting them at risk of exhaustion, disorientation, and injury. If a critical mass of birds is spotted circling at any point throughout the night, NYC Audubon works in partnership with the National September 11 Memorial & Museum and Michael Ahern Production Services to turn off the lights for roughly 20 minutes, which allows the birds to disperse.

 

NYC Audubon staff, board members, and 35 volunteers worked together in small teams to count birds for the 10-hour duration of the tribute. Our volunteers logged a collective 137 hours of monitoring!

This year we were able to station additional observers adjacent to and 28 stories above the tribute monitoring site thanks to our friends at the Battery Rooftop Garden. This new vantage point allowed us to validate the counts taken at the monitoring site below and observe the birds from a different angle.

 

Peak migration activity typically occurs around midnight, so we were surprised to see the number of birds quickly grow at 9pm. By 9:40pm, the birds were flying low enough that their night-flight calls were audible.

The lights were turned off at 9:49pm to allow the birds to disperse. When we counted over 1,000 birds at 10:55pm, the lights were shut off for a second time. The lights were switched off for a third and final time when low-flying birds became a problem at 12:30am.

 

We confirmed in each instance using radar that the birds had left the area before the lights were turned on again. All of us at the tribute breathed a sigh of relief when bird numbers dwindled after 1am and the birds that were present appeared to pass through the beams without becoming trapped. The lights remained on until 6am.

 

We observed many of the species that we have become accustomed to seeing in the beams, such as black-and-white warblers, northern parulas, Baltimore orioles, and American redstarts. There were also some more notable observations, including a hunting American kestrel, chimney swifts, yellow-billed cuckoos, a hummingbird, and a downy woodpecker that landed on the ledge of a nearby building.

In addition to monitoring birds, we monitored bats for the second year in a row. We also added an arthropod collection component. Andrew Farnsworth and his team from Cornell joined us on the roof to record night-flight calls and monitor the birds with radar. Among the insects collected this year were a praying mantid, numerous lady beetles, and predaceous diving beetles (pictured). We also saw and recorded the echolocation calls of several eastern red bats that were taking advantage of the insects congregated in the lights.
