The Society of Municipal Arborists has expanded their Arborist Exchange Program to include not just municipal arborists but also utility arborists and urban forestry nonprofit professionals. Applications are due December 29, 2018 for the 2019 exchange. Further details here.
For nearly 15 years, Nina Bassuk and her grad students at the Cornell Urban Horticulture Institute (UHI) have been developing hybrid oaks for exceptional tolerance of urban conditions (drought, alkaline soil, etc.) Bassuk now has 230 hybrid oaks of 2-3 inch caliper in her research fields. “I’d be happy for villages and cities in NY to plant them out so I can continue to evaluate them over time,” she says.
She is offering them to municipalities of any size in April of 2019. The cost would be $50 per tree to cover the B&B process. Communities could arrange for transportation or pick the trees up themselves. Bassuk says it would be preferable to have at least five trees go to any one community so she can efficiently evaluate them around the state.
If your community would like to plant at least five of these unique, new oak hybrids, please contact Nina Bassuk at firstname.lastname@example.org. Read on for more background about this fascinating research.
Through a $75,000 Urban Forestry Grant from the New York State Department of Environmental Conservation, Prospect Park Alliance recently surveyed roughly 12,000 of the park’s 30,000 trees as part of its work in caring for the Park’s natural areas.
The survey not only provides a more nuanced picture of the park’s evolving ecosystem, but important insights into the economic, environmental and health benefits of Brooklyn’s Backyard. Conducted by Davey Resource Group (DRG), a well-respected urban forestry consultancy that has worked extensively in New York City, you can examine the results on the Prospect Park TreeKeeper Interactive Map.
“The survey has provided exciting insight into what we already knew were some of the park’s most important treasures, its trees,” said Prospect Park Alliance President Sue Donoghue. “We are all aware of how special this urban green space is, but now with this data we can quantify the economic benefit our community receives from these trees. It clearly reinforces just how precious this resource is, and how we must all do our part to care for it.”
In April 2018, the Cornell Urban Horticulture Institute team of Nina Bassuk, Bryan Denig, Yoshiki Harada, and Barbara Neal released an extensive report on the elms (including American elms) of the National Mall in Washington, D.C. The report details a study conducted at the request of the National Park Service to examine the current conditions of the trees and soils on the tree panels of the National Mall, and it includes a fascinating history of the landscape. Here are some highlights from the report.
The National Mall elm trees are an important planting in the monumental core, yet they face several challenges. The soils of the tree panels are very compacted, most likely due to the constant pedestrian use and the numerous large organized events that take place on the Mall. Unevenness in the size and distribution of the tree canopy has resulted from decades of mortality (often due to Dutch Elm Disease) and the planting of certain elm varieties with growth forms that are seen as incompatible with the planting as a whole.
From June 17–20, 2017, the research team conducted a tree inventory and collected soil data and samples for later analysis. In addition, in November 2017, ground penetrating radar done by Council member Gary Raffel was used to document root growth for seventeen of the trees. This report deals with the current tree and soil conditions, while management recommendations are in a separate report to be released in late 2018 or early 2019.
Arboreta are a unique component of the urban forest, a place where we can see the breadth of beautiful trees and shrubs suited to our climate. They also make excellent outdoor environmental education labs.
For the 7th year, NYSUFC organizational member The Pine Hollow Arboretum in Slingerlands (a suburb of Albany), is providing an opportunity for area students to connect with nature in a meaningful way. The goals of the program are to increase overall environmental literacy and stewardship, to foster an appreciation for biodiversity, and to provide a venue for collaboration across socioeconomic and cultural barriers serving as a step towards community connectivity in the Capital District.
“I have American chestnut nuts that are starting to sprout,” he says. I send these nuts out free of charge to people that are interested in starting some mother trees, so they have a tree to cross with our blight resistant tree, when it is available.”
Nichols asks that folks read this post and the previous post about chestnut restoration, this document about mother trees and this one about planting your chestnut seeds, and then let him know how many nuts you want to plant! email@example.com or call 607-263-5105
New York Heartwoods (NYH), located in Kingston, was founded in 2011 out of Megan Offner’s love of forests, passion for quality craftsmanship, and desire to create environmental and economic solutions in her community. She says, “We make sustainable furniture—sustainable in that our pieces are made to last, are efficient in their use of materials, and are made with wood from fallen and urban trees that would otherwise be landfilled, chipped, or burned.”
In this post, NYC Parks Arborists Jessica Einhorn and Brooke Costanza answer questions about their deployment to San Juan, Puerto Rico from October 29-November 13, 2017. They were the first two NYC Parks arborists to be deployed to Puerto Rico following the devastation of Hurricane Maria, which made landfall on September 20, 2017 with sustained winds of 155 mph.
In addition to causing widespread human misery, Hurricane Maria wreaked havoc on the Island’s trees. A total of eight teams of New York City employees traveled to Puerto Rico to help out; each group was assembled based on what San Juan Mayor Carmen Yulín Cruz’s staff identified as a priority. Einhorn and Costanza performed forestry inspections with other NYC Parks staff and the NYC Office of Emergency Management.
Were your assessments guiding the work of arborists coming right behind you? Jessica Einhorn and Brooke Costanza: Absolutely they were. When we first arrived, it was apparent that the local government resources were stretched very thin, so we were tasked with creating our own plan of action on the spot. We started surveying the largest parks and created reports with recommendations for necessary tree work. After speaking with local Parks staff, we sent for additional NYC Parks’ arborists, climbers and pruners to help carry out this recommended work, as there were not adequate resources and expertise on the Island. At the end of our deployment, the arborists who took over continued inspecting trees throughout the City of San Juan.
A year ago, I wrote for the Council blog about the Urban Forest Carbon Registry, a non-profit organization based in Seattle. The Registry developed the first-ever Tree Preservation Carbon Protocol that enables urban forest preservation projects to earn carbon credits and bring in new funding sources. The Registry is working with urban foresters in a number of cities to help them develop both preservation and planting programs. In addition, many urban forest professionals serve as advisors and protocol drafters for the Registry. Here’s an update.
New Name: City Forest Credits
The Registry recently announced a name change: City Forest Credits. It’s still a non-profit registry issuing Carbon+ Credits for city forests (more about the “+” later). We found that the terms “urban” and “urban forestry” do not connect well with either funders or the person on the street. By contrast, the word “City” ties to resilient cities, smart cities, carbon neutral cities. We also believe that the buyers of City Forest Carbon+ Credits will include sustainability and water-neutrality buyers, so we wanted to emphasize the credit as well as the carbon.
NYSDEC recently launched its use of drones for things like monitoring coastal erosion on Lake Ontario, exploration of bat caves in Mineville, restoration of beach dunes on Fire Island, and monitoring Southern pine beetle in pine stands on Long Island. There are few known instances of drone use in the urban forests of New York; it’s thought that this is because people are worried about safety and are uncertain about the potentially prohibitive laws at work in populous areas.
However, the Council’s own Joseph Charap has begun using drones in Green-Wood Cemetery in Brooklyn with the help of his colleague, Vice President of Operations, Eric Barna. (Charap is Green-Wood’s Director of Horticulture and Curator.) Their first use of Barna’s Phantom 3 drone was to get aerial imagery of a veteran red oak (Quercus rubra) tree at Green-Wood that Charap suspected might be infected with oak wilt.
