Increased presence and recovery of wild species

The project at Poetto Beach in Cagliari, Italy, implemented by the municipality of Cagliari, began in 2022. It focuses on protecting and restoring the dune system while raising public awareness about the importance of preserving the coastal ecosystem. The project recognizes the delicate balance between environmental preservation and public enjoyment of Poetto Beach.
Key activities include installing barriers and signs to prevent trampling and littering, modifying beach access points to reduce erosion, and implementing significant interventions to restore the beach. These interventions involve strengthening anti-erosion measures with dune confinement and sand retention systems, as well as creating natural barriers (natural repopulation of native plants ) to protect the seashore. Public education initiatives aim to encourage responsible beach use and enhance understanding of the dunes' fragility. Additionally, new access walkways will be installed, and existing ones will be improved, including the creation of four wheelchair-accessible pathways to the water, designed for easy entry.
This comprehensive plan for protecting and enhancing Poetto's environmental resources is valued at €945,000 and is funded by the European Regional Development Fund.
Overall, the goal is to enhance environmental quality, promote sustainable beach use, and prevent both natural and economic losses. By balancing enjoyment of Poetto's natural resources with their protection, the project aims to ensure the long-term preservation of this valuable coastal area (Ref. 1, 2 & 4).

The D'Olive Creek Restoration project is designed to address the significant environmental challenges facing the D’Olive Creek Watershed and its tributaries (Tiawasee and Joe’s Branch), primarily caused by increased urbanization. Over the last several decades, the area has experienced severe erosion, sedimentation, and habitat degradation due to stormwater runoff from new residential and commercial developments. This runoff has led to stream channel instability, loss of wetlands, and impaired water quality in both D'Olive Creek and Mobile Bay, threatening aquatic and wildlife habitats (Ref 2).
The project involves restoring degraded streams and implementing management measures to reduce the downstream impacts within the watershed. Key activities include stormwater retrofits, stream restorations, and continuous monitoring. These efforts aim to stabilize stream segments and significantly reduce sediment loading into the northeast quadrant of Mobile Bay. This is crucial for improving water quality and clarity, which is necessary for re-establishing submerged aquatic vegetation (SAV) beds that serve as critical nursery areas for shellfish and finfish (Ref 1). By using natural materials like rock and living plants, the project also seeks to create a sustainable and ecologically balanced watershed system (Ref 3).
The anticipated outcomes include enhanced water quality in D'Olive Creek and Mobile Bay, reduced erosion and sedimentation, and the restoration of vital habitats, which will contribute to the region's overall ecological health (Ref 1, 3). This restoration project is part of a broader strategy outlined in the 2002 Comprehensive Conservation Management Plan for the Mobile Bay Estuary (Ref 1).

The Bela Flor Respira (BFR) project, also known as "ComBOA", is an urban agroecology initiative located in the Campolide neighbourhood of Lisbon, Portugal. This project exemplifies a transformative approach to community development and environmental sustainability by repurposing a neglected urban space into an agroforest. Launched in 2018 by the NGO Circular Economy Portugal, BFR engages local residents of the neighbourhood, from children to the elderly, volunteers, and academic partners, in creating a regenerative space that combines food production with social interaction (Ref 1). The project emphasises the co-production of public policies, fostering social cohesion through collective intelligence and civil society entrepreneurship (Ref 1). BFR’s innovative approach integrates syntropic agriculture, blending fruit trees, vegetables, and native species to create a resilient ecosystem that supports both the environment and the community. Through this initiative, BFR not only enhances urban green spaces but also strengthens community bonds, making it a model of sustainable urban development (Ref 3).

The Upper Detroit Riverfront Habitat and Parks Restoration Project aims to restore and enhance vital fish and wildlife habitats along the Detroit River. This initiative seeks to rehabilitate approximately 30 acres of upland and shoreline habitats within Riverfront-Lakewood East Park, A.B. Ford Park, and Mariners Park (all located alongside the river), covering nearly one mile of the Detroit River and its shorelines.
Key outcomes include improving approximately 1,000 linear feet of existing shoreline along the Detroit River by incorporating native wetland edges and fish spawning shelves into the restoration efforts. The project also plans to enhance around 2,000 linear feet of canal shoreline and 800 linear feet along Fox Creek to create or improve habitats for fish and herpetological species. In Riverfront-Lakewood East Park, 28 acres are targeted for the establishment or enhancement of native vegetation to support birds, mammals, and pollinators. If feasible, the creation of about 7 acres of wetlands, along with shallow and deep-water habitats, is also part of the vision.
The project is guided by the City of Detroit's 2017 Parks and Recreation Improvement Plan and represents part of a broader strategy to revitalize the city’s green spaces after years of underfunding. With renewed commitment, the city has allocated nearly $12 million to enhance neighborhood parks, particularly in areas that have lacked investment over the past decade.
However, the project was temporarily halted in 2020 due to high water levels causing flooding in the adjacent neighborhood. As of 2024, it remains on hold while the City of Detroit conducts a flood mitigation study. Despite this delay, the project remains a critical step toward fostering community stewardship and creating sustainable green spaces that improve the quality of life for all Detroit residents.

The Lower Salt River Restoration Project (LSRRP) is a riparian restoration initiative located along the Lower Salt River within the Mesa Ranger District of the Tonto National Forest. This collaborative project seeks to restore a section of the Lower Salt River Recreation Area that was severely impacted by the 2017 Cactus Fire. The Cactus Fire was a significant wildfire that caused extensive damage to vegetation and habitat in the area, highlighting the need for targeted restoration efforts to rebuild the ecosystem and mitigate future fire risks.
The LSRRP’s primary activities focus on removing invasive tamarisk trees, which are highly flammable and contribute to the intensity of wildfires, and planting native seedlings to reestablish local flora. By removing tamarisk trees, the project aims to create a landscape that is more resistant to fire, reducing the wildfire risk for the region. Additionally, the project supports the abundance and diversity of native plant species by removing invasive plants and planting thousands of native riparian tree species.
The restoration efforts also aim to enhance the riparian habitat by expanding two critical vegetation communities—the mesquite bosque and the cottonwood-willow gallery forest. These communities support rich biodiversity and offer essential habitats for local wildlife.
Beyond ecological restoration, the project emphasizes community involvement and awareness. It provides opportunities for the local community to participate in the project through environmental education events for K-12 students and ongoing volunteer involvement in monitoring and maintaining restored areas.
Overall, the Lower Salt River Restoration Project is a proactive effort to protect and revitalize the Lower Salt River Recreation Area, enhancing its ecological resilience and engaging the community in long-term conservation. (2-4, 6, 8, 11)

The Floating University was initiated in 2018 at the rainwater retention basin of the former Tempelhof airport in Berlin. Though not an official university, it serves as a space for transdisciplinary, communal learning, transforming an abandoned urban site into a vibrant community resource. The project reclaims the basin, hosting workshops and events that range from ecological lectures to cultural and art programs, fostering collaboration between diverse disciplines and communities.
The architecture collective raumlaborberlin originally envisioned the project as a six-month initiative. Artists, universities, and seminar groups contributed to designing the space and organizing workshops. However, due to its success, an NGO, Floating e.V., was established to sustain the project. Today, the NGO manages the site and continues its mission of engaging communities with urban and ecological themes.
After Tempelhof airport closed in 2008, the basin was infrequently cleaned, leading to contamination and sediment accumulation. Over time, a wetland ecosystem emerged, attracting plants, insects, birds, mammals, and amphibians. This natural development complements the Floating University’s infrastructure, which consists of open timber structures like a kitchen, art installations, communal spaces, vertical gardens, gardening beds, and an auditorium. These structures integrate seamlessly with the basin’s existing technical framework and wetland environment.
Floating e.V. aims to make the basin accessible to Berlin’s urban population while sparking discussions about urban climate, resource management, and water cycles through diverse and artistic programs. Smaller initiatives focus on specific ecological themes, such as plant diversity and soil health, through projects like a seed archive and soil lab.
The Floating University exemplifies how abandoned urban spaces can be revitalized into hubs for learning, creativity, and ecological awareness. (1-3, 8, 9)

The "Parque Espíritu del Manglar" in Cartagena is a multi-zone public space designed to promote recreation, environmental awareness, and cultural identity. The park, which has undergone a significant reconstruction, offers a wide array of recreational equipment and spaces for contemplation in a natural setting. It is divided into six thematic zones: Entrance Zone; Sports Area, Open-Air Theatre, the Tertulia Island, offering scenic views, public restrooms, and statues such as the iconic "Macondo" tree, a tribute donated by Gabriel García Márquez’s family; Children’s Central Zone, featuring a pirate-themed mangrove ship and an Environmental Observation Deck. (ref 1).
With the reopening of the park, EPA Cartagena introduced an ecological trail on Tertulia Island, where a mangrove restoration process has been carried out, focusing on plant health and climate resilience. This area also hosts wildlife such as macaws, sloths, turtles, raccoons, and green herons—species that cannot be reintroduced into their natural habitats. (ref 2)
The park now serves as an active site for environmental education, particularly for children, with programs addressing solid waste separation, climate change, and the protection of natural resources. Its reopening has also been recognized as a key step in strengthening family-oriented tourism and promoting sustainable urban development in Cartagena. (ref 2)

The Detroit RiverWalk is an urban development project along the Detroit River, designed to reconnect residents with their waterfront and revitalize a historically industrial area. Once characterized by abandoned buildings and industrial debris, the riverfront between the MacArthur and Ambassador Bridges had long been inaccessible to the public. To address this, the Detroit Riverfront Conservancy was established in 2003 to lead the redevelopment of this space.
The RiverWalk currently stretches along a 3.5-mile section, with plans to expand to 5.5 miles, integrating ecological restoration, public access, and recreational opportunities. The esplanade features native landscaping, artistic elements, and amenities, including four pavilions, a custom carousel, and areas for fishing, walking, biking, and inline skating.
Environmental remediation has been a crucial part of the project. In collaboration with the U.S. Environmental Protection Agency’s Great Lakes National Program Office, the Detroit Riverfront Conservancy successfully cleaned up 13,000 cubic yards of contaminated sediment, significantly reducing pollution and contributing to the removal of the Detroit River from the list of the most polluted sites in the Great Lakes. Furthermore, the project also includes greenways, park creation and revitalization.
The RiverWalk is not just a public space; it symbolizes Detroit’s transformation from a Rust Belt city to a sustainable urban environment. It exemplifies the power of public-private partnerships in revitalizing urban areas. The RiverWalk continues to expand, with plans to connect various parks and extend to the Ambassador Bridge, further enhancing the city’s waterfront. Its success was recognized in 2021 when it was named the Best Riverwalk in America by USA Today, cementing its status as a model for urban renewal and community engagement. (Ref. 1, 2, 3, 4)

Dudley, a historic market town in England and part of Birmingham's metro area, is reported to have some of the lowest rates of public access to nature in the country, ranking in the bottom 10% of governmental statistics for available greenspace relative to population density (Ref 1). To address this issue, the Dudley's Path to Nature Recovery project was launched in 2024 by the Birmingham and Black Country Wildlife Trust (BBCWT). The initiative aims to reduce inequalities in access to nature and create a greener future for local residents (ibid.).
Funded by the West Midlands Combined Authority, the project seeks to reconnect local communities with nature through five key activities: conservation work, community engagement, citizen science, partnership development, and the creation of new walking routes (Ref 1, 2, 3).
Among the project's activities, conservation efforts will include community engagement and focus on woodland improvement, heathland creation, and more. Additionally, the project will bring together key partners and community groups to explore collaboration models and identify potential sites for joint projects. Lastly, new walking routes will be created across the project’s landscape (Ref 1).

The Tres Rios Ecosystem Restoration Project is an ambitious initiative aimed at revitalizing a seven-mile stretch of the Salt and Gila Rivers in Phoenix, Arizona. The Tres Rios Environmental Restoration project involves the rehabilitation of nearly 700 acres in and around the Salt River, restoring a vital wetland and riparian habitat. Initially conceived in 1993 to tackle water quality issues and improve flood control, the project gained significant traction in the 2000s through a partnership between the City of Phoenix and the U.S. Army Corps of Engineers (USACE). Funding was structured with 65 percent from the USACE and 35 percent from the City of Phoenix and the Sub-Regional Operating Group Members, including Scottsdale, Tempe, Glendale, and Mesa.
The Tres Rios project encompasses habitat restoration, flood control, and recreational development, with the primary objectives being to restore a degraded ecosystem, enhance water quality, and provide new recreational spaces. Construction involved relocating 1.6 million cubic yards of earth to shape three large wetland zones and two deep-water retention basins. Additionally, 18,000 feet of underground water lines and 600 feet of 84-inch fiberglass effluent pipelines were installed. To establish a thriving wetland habitat, the project coordinated the planting of over 300,000 aquatic and terrestrial plants.
Habitat restoration efforts re-establish native vegetation and create wetland areas that support local biodiversity. The lush and scenic Tres Rios is now home to more than 150 different species of birds and animals like muskrats, raccoons, skunks, coyotes, bobcats, and beavers. By using treated wastewater to sustain the ecosystem, the project reduces dependency on natural water sources, thereby helping to mitigate water scarcity. The Tres Rios Ecosystem Restoration Project serves as a model for sustainable urban ecological initiatives, combining environmental health with community benefits. (1-8, 10-13)
