Short description of the intervention
The Circle Forest project, led by Arboretum Detroit in partnership with Detroit Future City, is transforming a vacant lot the size of a football field in the Poletown East neighborhood into a green space. Once used as a dumping site, the area is being revitalized with 200 native trees, including oak, elderberry, white pine, and juniper. Supported by local groups like Detroit Audubon, Singing Tree, and the US Fish and Wildlife Service, the project aims to improve environmental quality and provide better access to nature for residents. Since 2019, over 120 trees have been planted, with plans to develop a native meadow. This initiative offers a space for recreation and reflection, benefiting the local community, including a nearby nursing home and rehabilitation center. Beyond ecological restoration, Circle Forest fosters connections to indigenous knowledge and respects the wisdom of the original stewards of the land. (Ref.1, 2)

The primary beneficiaries of the Circle Forest project are the residents of the Poletown East neighborhood in Detroit, particularly those living near the newly restored green space. This includes individuals and families who gain access to a natural environment for recreation, relaxation, and education. Special consideration is given to residents of the adjacent nursing home and rehabilitation center, who benefit from the accessible, healing space. Additionally, the broader community benefits from improved environmental quality, enhanced biodiversity, and opportunities for cultural learning and engagement through the project’s educational initiatives. (Ref.1)
Measures for inclusion of marginalised groups
Arboretum Detroit installed an Americans with Disabilities Act Standards for Accessible Design (ADA) compliant boardwalk in Circle forest with the help of a grant from AARP Community Challenge Grant. (Ref.2)

Please specify the roles of the specific government and non-government actor groups involved in the initiative
Arboretum Detroit is the lead organization overseeing the Circle Forest project, responsible for planning, land acquisition, ecological restoration, and engaging the community. Detroit Future City plays a key role as a collaborator, focusing on improving green spaces and promoting sustainable urban development in Detroit.
Local residents contribute through volunteering for tree planting, land cleanup, and ongoing maintenance, fostering a sense of community ownership. Many also provide donations to support the project.
Detroit Audubon partners by offering expertise on local bird habitats and biodiversity, while the US Fish and Wildlife Service provides both a grant and guidance on native species restoration and maintaining ecological balance. Fungi Freights supports the initiative by introducing fungal networks to improve soil health and tree growth.
Additionally, the AARP Community Challenge awarded a grant for an ADA-compliant boardwalk. (Ref.2)

Impacts, benefits
Description of environmental benefits
-Lowered local temperature: “Our goal is to combat climate change on the local level and also to create shade and cooling,” (Ref.4)
-Improved air quality: “Birch is a native Detroiter who has lived in the neighborhood in the incinerator's shadow for the past 20 years. He formed Arboretum Detroit as a nonprofit in 2019 in response to the area’s poor air quality.[...]we’re doing this to create more oxygen and filtration."(Ref.1)
-Improved soil quality:”We will bring undulations to the landscape by forming small hills with valley rings around them. This will allow us to import better soil into the rings into which we will plant the tree groves.”(Ref.3)
-Increased restoration of ecosystems:”A native habitat restoration project” (Ref.2)
-Increased conversion of degraded land or soil:”We will bring undulations to the landscape by forming small hills with valley rings around them. This will allow us to import better soil into the rings into which we will plant the tree groves.”(Ref.3)
-Increased number of species present:”planting trees like Oaks, Sweet Gums, Black Gums, Hackberries, Sugar Maples, Cedars and many other natives that will provide food and shelter better suited to the native animal population.”(Ref.2)
-Improved control of invasive alien species:”We have begun by clearing the existing forest of garbage as well as invasive trees and plants.”(Ref.2)
-Enhanced support of pollination:”We are working with local partners Detroit Audubon, Singing Tree, US Fish and Wildlife, Fungi Freights, Gm Cares and many volunteers, to bring a native meadow”(Ref.2)
-Restoration of derelict areas/Increased green space area/increased restoration of ecosystems: “Like many abandoned lots in the city, Circle Forest was a dumping ground before Arboretum bought them…Arboretum Detroit is working to transform 12 vacant lots in the city’s Poletown East neighborhood into an oasis of 200 trees called Circle Forest.”(Ref.1)

Description of economic benefits
1.Generation of voluntary work opportunity: "With the help of volunteers, the goal is to cover it in native trees like oak, elderberry, white pine, cedar, juniper, and tupelo. [...] a host of volunteers filled two dumpsters with discarded roofing, toilets, pools, beds, and other random trash as they cleaned the area."(Ref.1)
Description of social and cultural benefits
-Improved access to urban green space: “We want to improve the quality of life of the people in these neighborhoods and create access to nature and opportunities for kids to have a place to run free and play.”(Ref.2)
-Increased visibility for indigenous peoples: "we recognize indigenous wisdom and are willing to listen to the original stewards of this land and to the landscape herself."(Ref.2)
-Increased opportunities for social interaction: "[..]opportunities for kids to have a place to run free and play.[..] “These kids were hanging from trees while they’re writing poetry and it was really beautiful to see the forest activated in that way. Life breeds life."(Ref.1)
-Increased involvement of locals in the management of green spaces: "A community is forming around this project unlike any we have undertaken. With the help of volunteers, the goal is to cover it in native trees like oak, elderberry, white pine, cedar, juniper, and tupelo."(Ref.3,1)
-Gain in activities for recreation and exercise: "Free Yoga at Circle Forest"(Ref.8)
-Promotion of cultural diversity: "Let us hone our intercultural competency and recognize the value of Indigenous Knowledge."(Ref.2)

Description of locals satisfaction with the project
“Every time I’m up here, I see kids running around, or workers from that facility over here catching a smoke, neighbors over here building a fire and cooking breakfast, it’s amazing,” he says. “It’s here for people and people are finding it.”(Ref.1) "It's now a place where people can walk in, take a breath and feel like they're somewhere else," he says. "We have meetings there, camps come through, and just the other day some kids were sitting in the trees writing songs." "There's been a vibe of people understanding that this was such a traumatized landscape. And, if we can do anything to heal it, we're doing good." (Ref.5)
