Eagle Reef Project
The Eagle Reef Project was launched to restore the health of Mobile Bay in response to habitat loss and declining fish populations due to the degradation of oyster and seagrass beds [REF 1, REF 6]. Originally planned in 2022 as an Eagle Scout service project by John Shell of Boy Scout Troop 147, the project has grown into a regional environmental initiative supported by Partners for Environmental Progress (PEP), the University of South Alabama’s Stokes School of Marine and Environmental Sciences, and municipalities such as the City of Fairhope [REF 3, REF 4, REF 7].
The project deploys preassembled mini reefs—constructed from plastic and PVC—beneath docks and piers across Mobile and Baldwin counties. These reefs, once colonised by filter feeders like oysters and barnacles, can filter up to 20,000 gallons of water daily and serve as habitats for fish, shrimp, and crabs [REF 1, REF 4]. The initiative aims to improve water quality, sequester nutrients, reduce algae, and restore marine biodiversity [REF 1, REF 6].
The Eagle Reef Project addresses critical coastal hazards, including water pollution, fish habitat loss, and the legacy of environmental disasters such as the Deepwater Horizon oil spill [REF 4]. It combines scientific monitoring, civic engagement, and scalable design to enhance the region’s climate resilience and ecological health [REF 1, REF 6, REF 7].

Murphy High School Farm to Table
Launched in 2022, the Murphy High School Farm-to-Table Program in Mobile is an initiative aimed at addressing urban food deserts and promoting community health through education and sustainable farming practices [Ref 1; Ref 4]. Funded by Spire as part of its “Connected Through Cooking” initiative, the program transforms 28 acres of school grounds into a teaching farm where students learn to grow and cook nutritious food [Ref 1; Ref 6].
The project integrates science, math, and culinary arts into hands-on learning, engaging students in planning, planting, and harvesting crops, as well as developing healthy recipes [Ref 1; Ref 4]. Activities include constructing greenhouses, building raised beds, and installing irrigation systems—33 raised beds and an 800 sq. ft. greenhouse were completed in the first year [Ref 1; Ref 2]. The program also supports nearby food-insecure neighbourhoods by distributing produce and recipe tips, helping address poor access to fresh food in Mobile [Ref 3; Ref 4]. Younger students from local schools are included through farm-based learning, broadening the program’s educational reach [Ref 1; Ref 5].
Key actors include Murphy educators, Spire staff, and community partners such as Jones Valley Teaching Farm and Auburn University [Ref 4]. Outcomes include improved STEM education, increased food literacy, and stronger community ties through urban agriculture [Ref 1; Ref 4].

Mobile Tree Trial
The Mobile Tree Trail is a nature-based solutions (NBS) initiative aimed at preserving Mobile, Alabama’s urban forest while celebrating its cultural and ecological heritage (Ref 1, Ref 2). First established in the early 1990s by volunteers, the original trail featured 24 iconic trees, selected for their historical significance, environmental value, and beauty (Ref 1, Ref 2). Over the years, some trees were lost to development and storms, and the trail faded into obscurity (Ref 1, Ref 4).
From 2021, the Mobile Tree Commission, with support from The Nature Conservancy, is leading efforts to revive the trail (Ref 3, Ref 6). Activities include reviewing past entries, opening public nominations, and selecting new trees that best represent Mobile’s identity (Ref 3, Ref 4). The project emphasises inclusivity and public participation, welcoming volunteers and local input to shape a trail that evolves with the city (Ref 4, Ref 6).
Mobile faces environmental threats such as hurricanes, urban expansion, and loss of native tree cover (Ref 1, Ref 6). The revitalised trail helps address these challenges by promoting awareness, conserving old-growth specimens like the 300-year-old Duffie Oak, and maintaining vital green spaces (Ref 4, Ref 6).
The Mobile Tree Trail blends education, tourism, and conservation, enhancing urban resilience while telling the city’s story through its trees (Ref 3, Ref 6).

Lower Perdido Islands Restoration
The Lower Perdido Islands – Bird, Robinson and Walker Islands – are located in the Perdido Pass, in Orange Beach. The area is a popular destination, attracting many visitors due to its blue-green water and diverse wildlife, which, however, leads to erosion from boat wakes and marine debris. Its popularity impacts these wildlife habitats, including the seagrasses, marsh and forests which provide habitat for nesting birds and nurseries for local fish. Therefore, the Nature Conservancy, the City of Orange Beach, Moffatt & Nichol, and Olsen Associates Inc. started working together in 2017 to create a conservation management plan for the Perdido Islands, as well as develop some restoration initiatives to support this critical habitat for the future [1,3]. This Lower Perdido Islands' restoration project is part of a larger Perdido Bay Watershed restoration plan [2]
Agoa Sanctuary
The creation of the AGOA Sanctuary was first envisioned in 2006, officially established in 2010, and continues to evolve as a vital initiative for marine conservation. Located in the waters of the French Antilles, the sanctuary encompasses the entire Exclusive Economic Zone of Martinique, Guadeloupe, Saint-Martin, and Saint-Barthélemy. Spanning 143,256 square kilometers, it is the second-largest marine protected area in France, just behind the Coral Sea Natural Park in New Caledonia.
AGOA was established to ensure a favorable conservation status for marine mammals, aiming to protect both the species and their habitats through a combination of direct and indirect actions. The sanctuary’s long-term strategy is grounded in five core principles: reducing harmful interactions between human activities and marine mammals; enhancing scientific understanding of these species, their habitats, and the pressures they face; increasing public awareness and disseminating knowledge about the sanctuary; strengthening collaboration with governmental agencies for effective surveillance and enforcement; and fostering regional cooperation with Caribbean nations under the Cartagena Convention and its SPAW Protocol.
Together, these guiding principles reflect AGOA’s commitment to sustainable stewardship of marine biodiversity in the French Antilles, creating a lasting sanctuary for marine mammals in the Caribbean. (1, 2, 3)

Ecological & Citizen Restoration Project in Carbet
The Ecological & Citizen Restoration Project in Carbet, led by ASSOMER, supports the city in sustainably developing its coastline. This coastal area serves multiple purposes—recreational, economic, and subsistence—making it essential to include the voices of its key user communities: fishermen, restaurateurs, residents, and tourists.
However, both these uses and critical spawning habitats are increasingly threatened by coastal erosion, which is worsened by urbanization. Beyond reducing nesting areas, urban expansion also creates light pollution, which disrupts nesting females and hatchlings that rely on moonlight reflections to navigate.
This project was selected during the inaugural Biodiversity Lottery, a French government initiative inspired by the Heritage Lotto (established in 2018). The funds will be dedicated to protecting Carbet’s turtle population. Key efforts include reforesting the beach to combat erosion and creating new nesting spaces for turtles.
By restoring vegetation in a way that addresses multiple environmental challenges, this initiative aims to raise public awareness and ensure long-term coastal preservation. (1,2)

Treetroit
Over the past century, vast portions of the world’s oldest forests have been lost to clear-cutting and managed forestry (1). Arboretum Detroit is working to counter this trend by reforesting Detroit’s urban landscape, transforming abandoned city blocks into thriving groves of trees (1). Each parcel of land features trees that showcase the unique contours and characteristics of specific species, creating a diverse urban forest mosaic across the city (1). These "forest patches" are protected, designed to mature safely for generations, offering a space of tranquility and natural beauty for all Detroiters (1).
Arboretum Detroit’s main goal is to cultivate environmental consciousness, inspiring the community to consider our interconnectedness with nature and our impact on it (1). Through their reforestation mission, they demonstrate the ecological, cultural, aesthetic, and economic value of trees, both locally and globally (1). Trees alter our environment by using their leaves to filter the air we breathe by removing dust and other particles. Deciduous shade trees cool homes in the summer and allow the winter sun to heat homes when they lose their leaves. Trees can serve as a windbreak. The more compact the foliage on the group of trees the more effective the windbreak. Their pilot project, launched on Earth Day 2019, brought these values to life. Volunteers and members planted 21 trees across the site, including species like Princeton Sentry Ginkgo, Redpoint Red Maple, Paper Birch, Cedar, Yew, and understory trees like Kousa Dogwood and Forest Pansy Redbud, enhancing the habitat for local pollinators and birds (2). The trees were arranged in trios, interspersed with native seeds, soil, compost, and glacial boulders to create a healthy and engaging environment for all (2).

Renatura pilot: Fast Forests for Lisbon
The Mediterranean climate in Lisbon, already characterised by low precipitation, has been further exacerbated by climate change. The city faces challenges related to biodiversity loss, urban loneliness, and climate anxiety (1). To address these issues, Lisbon's urban development plans have prioritised the re-naturalisation of urban spaces and the integration of ecological networks. Urban nature is now a central component of the city's Master Plan (2012) and other strategic agendas (1).
It is being developed by the LISGREEN project, which aims to enhance ecological connectivity and mitigate the effects of urban heat islands in Lisbon. By establishing nature-based solutions, it aims to restore forests within the city (1, 2, 3). This project encompasses different strategies, such as the RENATURA pilot project. It is a collaboration with the NGO URBEM and involves active public participation in tree planting and forest maintenance. This initiative aims to educate the community about nature, promote well-being, and mitigate extreme climate events (1), through the creation of urban forests.
The main strategy is to create fast forests using the Miyawaki method, which involves dense planting of native trees, removal of invasive plants, and intensive initial care. This approach accelerates the growth of natural forests within a short period, using native species and reducing the need for watering (1)
The first fast forest was developed in Parque Casal Vistoso within Bela Vista Park, within the Eastern Green Corridor of Lisbon. The park is being underutilised because of the lack of shade (1). Thus, this initiative encouraged volunteers to participate in tree planting and forest maintenance activities (3). The NbS intervention began with a 300m² experimental plot near the Vale da Montanha pedestrian bridge and has since expanded to a new 1,500m² plot on the opposite side of the bridge (2). Over 500 volunteers joined the effort, planting more than 3,800 trees (1)

Gothatuwa Wetland Park
Sri Lanka, particularly its low-lying coastal areas, faces recurring flooding challenges exacerbated by climate change, coastal erosion, and urbanization (1). Wetlands have emerged as crucial ecosystems in mitigating these risks, acting as natural sponges during heavy rainfall and releasing water gradually as flood levels subside (1). Beyond flood control, wetlands play a vital role in environmental quality. Their biodiversity helps filter pollutants and chemicals from the air and water, creating a healthier environment for both humans and wildlife (1). In 2018, Colombo was designated as a Global Wetland City under the Ramsar Convention, becoming the first and only capital city to receive this recognition (1). Recognizing the significance of wetlands as nature-based solutions, international institutions have prioritized their conservation through financing programs (1), and the city has developed projects to raise awareness and involve its citizens in their protection (1). These efforts have resulted in the creation of four wetland parks in the city, that comparing to a wetland, the wetland parks have more human intervention. Thus, they are focused on different topics and activities (2): Diyasaru Park, Beddagana Wetland Park (managed by the Urban Development Authority), Kotte Rampart Wetland Park (managed by the Urban Development Authority), and the Gothatuwa Wetland Park (managed by the Sri Lanka Land Development Corporation) (2). Gothatuwa Park is the newest wetland park and it is located in the flood-prone Gothatuwa neighbourhood (1). Inaugurated in 2024, It has a recreational focus, with trails for cyclists and hikers, and together with the other wetland complex, this park is designed to make the wetlands a cornerstone of local people's lives (1). Currently, environmental education activities are carried out in the park, focusing on managing aquatic invasive plants, tree planting and solid waste collection (3).
Thalangama Wetlands
The Thalangama wetlands are part of a network of wetland ecosystems around Colombo city that spread over 20 km2 and provide critical life support to the city. These ecosystems keep people safe from floods, cool the air, filter polluted water, provide food and medicines, and fight climate change (10). These wetlands have become an environmental protection area and a biodiversity hotspot in a rapidly urbanising environment, as they host an array of plants and animals, including the endangered fishing cat and otter (5, 10). In 2007, Thalangama Lake and its surroundings were declared an Environmental Protection Area (EPA) under the National Environmental Act (4, 5). This protected area covers approximately 118 hectares (4) and includes two man-made reservoirs: Thalangama Tank (11 ha) and Averihena Tank (3.2 ha), located just 300 meters apart (5). The area hosts floating and rooted plants, scrublands, and trees that provide habitat to up to 100 species of migratory, resident, and endemic birds throughout the year. In addition, the area supports 30 species of dragonflies, 12 species of reptiles, 10 species of mammals, and 15 species of freshwater fish (1, 4). Since the lakes and their surroundings were declared an EPA, only limited uses are permitted, such as traditional fishing and rice cultivation (4, 5). The lakes are also important for floodwater retention and have high scenic and aesthetic value, attracting many visitors, and scientific and educational activities (5, 13).
However, due to the area's rapid urbanisation, land values have increased significantly, leading to excessive landfilling and the reclamation of paddy lands for housing. This is compounded by the indiscriminate disposal of garbage and construction waste and the spread of invasive species (5). These challenges have also led to the engagement of surrounding communities in managing and maintaining it (11).
