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).

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)

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).

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).

The stretch of the Great Lakes basin ecosystem from southern Lake Huron through western Lake Erie forms a unique urban refuge where life thrives with beauty and resilience. Known as Metropolitan Detroit, this region is where the Community Foundation for Southeast Michigan and many partners are working to create The Great Lakes Way by connecting 160 miles of greenways and 156 miles of water trails (1).
The vision for the Great Lakes Way project is to ensure that all residents and visitors of southeast Michigan—people of all ages, backgrounds, ethnicities, abilities, and interests—feel connected to the water resources, welcomed on its trails, and able to enjoy the benefits and opportunities these access points provide (1). To bring this vision to life, the project plans to link 160 miles of greenways and 156 miles of blueways, connecting people to a range of world-class freshwater, wildlife, and recreational opportunities. These include fishing areas, bird migration pathways, parks, working waterways, preserved woodlands, and restored wetlands (2).
The Great Lakes Way project connects existing assets, supports accessibility and equity, and promotes the Great Lakes Way to both residents and visitors through marketing and communication efforts (2). There are 26 points of interest that will serve as connection hubs along the Great Lakes Way (2). In Detroit specifically, the focus is on connecting 13 culturally or historically significant destinations, as well as locations known for their environmental and ecological importance or as regional landmarks (2).
Rich in world-class fisheries, migratory flyways, parks, urban centers, small towns, preserved old-growth woodlands, and restored wetlands, the Great Lakes Way offers unique experiences that can only be found here. By uniting the natural and cultural assets the Great Lakes Way designation aims to emphasize and expand the essential linkages needed to further connect this remarkable region. (2,3)

The Bee Park Molentargius is a project located in the Molentargius-Saline Regional Natural Park, in Cagliari. It is part of a broader effort to regenerate abandoned and underutilised urban spaces, transforming them into areas that support biodiversity, promote sustainability, and engage the local community in environmental stewardship (3,4). The primary goal of the Bee Park Molentargius project is to restore specific areas of the Molentargius Park to their original ecological and productive functions. It aims to enhance biodiversity, support sustainable agricultural practices, and promote environmental education. The project includes the creation of shared gardens and an educational apiary, designed to reclaim the park’s identity and encourage local participation in the management and preservation of this important natural resource (1,3). It was developed with financial support from the Autonomous Region of Sardinia and the European Union's Horizon Europe Framework Programme. Inaugurated in March 2024, the project is a collaborative initiative involving local citizens, institutions, and park beneficiaries. It includes various educational components, such as beekeeping and olive growing training courses, along with sensory analysis workshops for honey and olive oil. These activities are intended to educate the public while fostering a sense of community ownership and responsibility toward the park​ (1,2). The project indirectly addresses environmental hazards related to the degradation of urban green spaces and loss of biodiversity. By restoring the park’s natural and productive functions, the Bee Park Molentargius helps mitigate risks associated with urbanisation, such as habitat loss and the decline of pollinator populations, which are crucial for maintaining ecological balance and food security​ (3)

The beach of Vétiver, located in the municipality of Case-Pilote, is one of the most important nesting sites for the critically endangered hawksbill turtle (Eretmochelys imbricata) in Martinique. It is also a nesting ground for the green sea turtle (Chelonia mydas), another endangered species. As one of the last minimally urbanized beaches in the North Caribbean of Martinique, the site plays a vital role in the conservation of these species. In addition, fishing restrictions in the area significantly reduce the risk of turtle mortality caused by accidental capture in fishing gear, which is the leading cause of human-related sea turtle deaths in the Antilles.
However, the site faces several stressors that hinder successful nesting. The surrounding vegetation is severely degraded due to invasive alien species, and much of the shrub and tree cover has disappeared from the backshore, where turtles prefer to nest. Without adequate vegetation, hatchlings are left exposed to the heat. Additionally, the beach is frequently disturbed by local residents and visitors for recreational activities. With no designated parking area, cars often park directly on the beach, compacting the soil and further limiting the chances for vegetation to recover or turtles to dig nests. This compaction forces turtles to lay their eggs closer to the shoreline, increasing the risk of nests being washed away by heavy swells.
In 2022, the non-profit organization "Asso-mer" and its partners launched the Véti’Vert project on a previously neglected public green space. Through environmental restoration efforts, they created a nesting enclosure on the backshore to mitigate these stressors and improve the conditions for sea turtle nesting. The project also engaged with local residents to increase the chances of success (Refs 1-3).

MINI Ireland, in collaboration with conservation charity Earthwatch Europe, has launched Ireland's first "Tiny Forest" at the Tolka River Project, a community-driven rehabilitation program in Co. Dublin. In a space the size of a tennis court (195m²), nearly 600 native trees have been planted, creating a densely packed, environmentally efficient green area.
This partnership with Earthwatch aims to raise awareness for local environmental projects and foster community bonds. Green spaces like this offer valuable areas for people to connect with nature, exercise, unwind, and reduce stress—one reason the Tolka River Project center was chosen as an ideal location. "Tiny Forests" are remarkable for their impressive efficiency within a small footprint: by planting 600 native trees closely together, the forest grows naturally with increased density, achieving up to 30% more plant density, ten times faster growth, and up to thirty times better carbon dioxide absorption. Over the next three years, this forest is expected to attract more than 500 animal and plant species, transforming into an accessible mini-ecosystem.
The project uses a variety of locally sourced native trees, including silver birch, alder, hazel, hawthorn, and gorse, which together will form the natural layers of a forest. Ireland's first Tiny Forest was planted on March 22, 2023, at the Tolka River Project site in Dublin's Buzzardstown area. The Tiny Forest, located near the center, will serve as a space for reflection and recovery, supporting clients on their journey to rehabilitation. The planting event was a day of celebration, with Tolka River Project clients and MINI Ireland staff working side-by-side to create this thriving green space.. The space is utilized to create recovery-focused programs, including mindfulness and yoga, while functioning as a social gathering area (7).

Mapinguari National Park, located in the Amazon region of Brazil, is a protected area distinguished by its rich biodiversity and vast expanse of untouched tropical rainforest (2). It was officially created on June 5, 2008, by decree, covering an area of 1,776,914.18 hectares (2). The Chico Mendes Institute for Biodiversity Conservation (ICMBio) manages the park. It is linked to a management plan encompassing several nearby conservation units and their areas of influence (2, 3). Its main goal is to preserve the valuable natural ecosystems and scenic landscapes of the Purus-Madeira interfluvial region, which includes savanna enclaves (2, 3). The ecoregion where it is located has a high priority for botanical conservation due to parameters such as species richness and endemism (3). Additionally, the area presents great environmental heterogeneity, with several isolated and unique ecosystems, aspects that have been considered for fostering scientific research and public visitation, with programs for environmental education, recreation in contact with nature, and ecotourism (3). On March 8, 2013, an advisory council for the park was established to involve various stakeholders in decision-making and the effective conservation of the park (2), and in 2018 a Management Master Plan was established, seeking to develop an integrated approach for the protection and proper management of the region, especially considering the socio-environmental impacts of the construction of the BR-319 highway and the deforestation caused by fires, the expansion of soybean cultivation, land appropriation (7) and cattle ranching from the neighbouring state (3, 10). It was established as a Natural Park in 2008, but over the years it has undergone changes in land regulations, adding or decreasing its size as certain mining activities have been allowed in the buffer zone (2)

The initiative focuses on the creation and implementation of a management plan for the Natura 2000 areas of Ciurbesti Lake and Fânațele Bârca to protect their biodiversity and promote sustainable tourism and land use. These areas were designated as part of the Natura 2000 network in 2016, but until recently, lacked a formal management plan. In 2019, the environmental group "Asociaţia Scutierii Naturii Bacău," in partnership with the Environmental Protection Agency of Iași (APM Iași), secured EU funding to develop the plan. While the plan was being developed, minimal regulations were established in 2022 to ensure interim protection.
The finalized management plan was released in 2024. It assessed species and habitats of European, national, and community importance, identifying 18 bird species, 3 plant species, 1 mammal species, and 4 key habitats. The plan also identified environmental pressures and set objectives and actions to ensure the conservation of this biodiversity. Before the plan's completion, two rounds of public consultations were held, involving a broad range of stakeholders, including surrounding municipalities, private landowners, public administrators, and local community representatives, to define optimal management practices.
The plan mandates continuous monitoring and reporting on the state of species and habitats. It also includes specific conservation measures, such as the partial reconstruction of endangered habitats, meetings with local land users to restrict harmful activities, public awareness campaigns, and regular monitoring. Additionally, it emphasizes the sustainable use of the area, including tourism. The creation of the plan was financed with EU funds totaling €1,036,014.27, and the projected cost for its implementation is €259,627.99. (1-5)
