    Background

    The Urban Ecology Center was founded in 1992 following local efforts to address crime and environmental deterioration in Milwaukee’s Riverside Park. Early activities included neighborhood-led park cleanups and informal environmental education programs for local students. 2

    The organization later expanded its operations beyond Riverside Park, opening additional locations in Washington Park in 2007 and in the Menomonee Valley in 2012. These expansions were tied to broader redevelopment efforts in those areas, including partnerships with local organizations involved in park restoration and urban planning. 2

    Over time, the organization has grown from a neighborhood initiative into a multi-site nonprofit focused on environmental education and access to urban outdoor spaces. 2

    Activities and Advocacy

    The Urban Ecology Center conducts environmental education programs, recreational activities, and conservation efforts in Milwaukee parks. Its programming includes school-based science education, community outdoor activities, and environmental stewardship initiatives such as habitat restoration. 1

    In addition to programming, the organization engages in redevelopment and land-use activities connected to its mission. According to its 2024 tax return, UEC reported making a $5,584,000 grant to the UEC Supporting Land Organization for building redevelopment. It also reported a $33,081 grant to the UEC Land Corporation for operational support. 3

    UEC also generates revenue through fundraising events. Its 2024 tax return reports that the Summer Solstice Soirée generated $214,211 in gross receipts, while HKE MKE generated $51,515 in gross receipts. 4
