Habitat mapping, restoration and monitoring-focused management

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]

Located southeast of Bayou La Batre, Coffee Island is a barrier island that provides a buffering capacity for shorelines in Mobile County [5]. Since 1950, the shoreline on the island has been eroding. In response, the Nature Conservancy has put in a ‘’living shoreline’’ construction in 2010 to reduce wave energy and decrease erosion the island has been facing [1]. A ‘’living shoreline’’, ‘’refers to the use of nature-based techniques and materials such as oyster shells, reef blocks, bagged shells, live shellfish, and plants to help protect eroding shorelines’’ [2]. While the living shorelines constructed in 2010 still provide habitat benefits, these efforts no longer protect the shoreline from erosion. This in turn threatens not only the island's buffering capacity, but also the integrity of the marsh on the island [5]. Therefore, the Nature Conservancy has secured funding for a second project on the island, the Coffee Island Restoration project (in 2023) that aims to implement a (longer) 5,000-foot living shoreline breakwater, including the use of ‘’super sacks’’ – a specific kind of sediment barriers functioning as dikes – to protect the coastline while enhancing habitat [4, 6]

In 2012, PRZHT (Pôles Relais Zones Humides Tropicales) initiated Project REMA, an effort dedicated to the conservation and rehabilitation of ponds in the Antilles, with backing from the IUCN. Wetland ecosystems in Martinique and the Caribbean had long been overlooked. However, interest in these habitats grew after PRZHT introduced an interactive virtual tour of Antilles ponds in 2019. Project REMA emerged in response to local concerns about the lack of technical resources for pond restoration in the French West Indies. While similar initiatives had been undertaken in France, there was no specific guide tailored to this region. Though originally conceived in 2012, the project remained dormant for several years before fully launching in 2019. Between 2019 and 2021, restoration experiments were conducted on 12 ponds across Martinique, Guadeloupe, and Saint-Martin, laying the groundwork for a comprehensive technical manual.
Building on this success, REMA II was introduced in January 2024 with a three-year scope. This new phase will focus on restoring and maintaining 80 ponds, both public and private, in Martinique and Guadeloupe. Additionally, it will address the management of invasive species and incorporate eDNA analysis to enhance conservation efforts. These small wetlands play a fundamental role in flood regulation, water storage, pollutant filtration, erosion control, and carbon absorption. They also provide refuges for biodiversity and contribute to the resilience of territories in the face of climate change.

In May 2020, CityLAB Berlin launched "Gieß den Kiez", an interactive platform designed to support Berlin's urban trees by fostering collaboration between citizens and the city. The platform enables voluntary civil society efforts to help water the city's endangered tree population. It features a map that visualizes nearly all of Berlin's street and park trees, complete with data such as water requirements, age, and species. Citizens can create profiles, adopt trees, and mark them as ‘watered’ within the app, making it easy to track contributions to the health of Berlin’s trees. (Ref. 2)
Berlin's trees face growing challenges due to increasing temperatures, reduced rainfall, and exposure to road salt in winter. The hot summers of 2018 and 2019 highlighted the urgency of supporting the city’s trees, which provide cooling shade, clean air, and habitats for numerous animal and plant species. To address this, "Gieß den Kiez" was developed as a platform where authorities, volunteers, and civic society could collaborate to prevent tree dehydration.
The platform maps over 625,000 trees across Berlin and offers additional tools, such as rainfall data from the last 30 days and the locations of public water fountains, which can be used for watering trees. By connecting data from city authorities, the German Weather Service, and OpenStreetMap, the fully open-source platform allows for transparency and accessibility in its operation. (Ref. 6)
The project has proven highly successful in Berlin, with over 10,000 participants actively watering trees, and its model has been adopted in other German cities like Leipzig. "Gieß den Kiez" not only exemplifies a practical response to urban climate challenges but also fosters a sense of shared responsibility and community engagement in caring for urban green spaces.

The Acropora Project is a coral restoration initiative launched in 2015 by the Martinican Regional Directorate of Environment, Planning, and Housing, primarily implemented by the nonprofit organization Assomer. It focuses on two critically endangered Caribbean coral species: Acropora cervicornis and Acropora palmata, as classified by the International Union for Conservation of Nature. While Acropora palmata thrives on the Atlantic seabed of Martinique, Acropora cervicornis had seemingly vanished from local waters by 2007, despite previously providing crucial habitats for marine life. However, this species was rediscovered in 2013 at Loup Caravelle on the Atlantic side of Martinique.
The initiative began by extracting cuttings from both species at Loup Caravelle and nurturing them at a separate site in Le Diamant. In 2019, these corals were transplanted to three locations on the seabed of Sainte-Luce, demonstrating surprising growth patterns despite the site's low to medium environmental quality.
The project's primary aim was to prevent the permanent disappearance of both coral species through spatial replication techniques, including cutting and transplantation. Particular attention was given to enhancing the genetic variability and range of Acropora cervicornis. The initiative also aimed to raise awareness about current coral conservation challenges.
Additionally, the project included a research component that contributed to a better understanding of environmental conservation and the restoration of Acropora cervicornis populations. Unfortunately, a temperature increase at the end of 2023 resulted in the decimation of all corals at the transplant sites. (Ref. 1 -5)

Arizona is experiencing an unprecedented drought, now nearing 15 years and surpassing the most severe drought in over 110 years of recorded history (1). For Phoenix residents, accustomed to extreme heat and minimal rainfall, rising temperatures are bringing new health risks (3). Diminished rainfall not only leads to water scarcity but also raises temperatures, as the sun’s energy, instead of being absorbed to evaporate moisture, intensifies the heat on the ground (2). In 2023 alone, extreme heat claimed at least 147 lives, with Arizona seeing the majority of these fatalities. By early August, over 100 heat-related deaths had been reported in the state (2).
In response to these challenges, the Watershed Management Group (WMG) has collaborated with Arizona State University’s Sustainability Teachers’ Academies to develop a program that maximizes the desert’s limited rainfall to build community resilience (3). Their Schoolyard Water Education Program brings educational services to Phoenix schools, focusing on designing and installing rain gardens as part of outdoor learning initiatives (3). This hands-on approach transforms schoolyards into interactive laboratories where students learn the principles of sustainability through direct engagement with their surroundings (3).
A project at Clarendon Elementary School in Phoenix involved constructing a rain garden with native plants and wood chip mulch to help retain moisture (3). These gardens offer students a living classroom, where they can observe seasonal changes in native plant life, distinguish beneficial species from invasive weeds, and track rainfall to measure the garden’s water intake from rooftops and direct rain (3). Beyond the academic learning, rain gardens provide cooler, safer spaces for students to gather, fostering a lasting connection with nature and a deeper understanding of sustainable water practices (3).

This project aims to increase water retention capacity in the landscape around urban areas and promote biodiversity by restoring wetlands and natural streams in the forested areas on the island of Hisingen in northern Gothenburg. Many wetlands and streams in the area have been drained or otherwise affected by human activity, reducing biodiversity, increasing the risk of floods and droughts and causing greenhouse gas emissions from peatland. The goals of the project are to reduce the risk of floods downstream, reduce the effects of dry periods, increase groundwater infiltration and benefit species living in and around wetlands and streams in the forest [Ref. 1-3]. The Swedish Anglers Association has initiated the project in cooperation with the City of Gothenburg and the environmental engineering company Miljöteknik I Väst AB [Ref 1]. The project's first stage is a continuation of an earlier project to make an inventory of wetlands and their status [Ref 1, 2]. For the second part, 6,9 ha of wetlands and streams on land owned by the city were restored [Ref. 1, 3]. The project will lead to further efforts in wetland restoration around Gothenburg [Ref. 2, 4].

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)

"Urban Natural Area Ciric" is an initiative aimed at designating the forest and lakes of the Ciric area, located on the outskirts of the city of Iași, as an Urban Natural Area. To achieve this goal, the initiating organizations—NGO Civica and the Ornithological Association of Iași (SOR)—have developed a comprehensive report focused on the Ciric natural area, which monitors species and habitats while identifying pressure points on biodiversity and necessary conservation actions, as well as the benefits these areas provide.
In the Ciric area, various flora and fauna species have been identified, with some holding high protection status (14 bird species) or being of community importance and conservation interest. However, this ecological richness faces threats, as factors such as rapid urbanization, water pollution, and waste disposal have been identified as significant risks to the ecosystems.
In response to these challenges, the NGO aims to collaborate with the municipality to create protective municipal laws that will not only recognize the area as an Urban Natural Area but also ensure its inclusion in development plans. This partnership seeks to establish regulatory measures and strategies that will safeguard and enhance the biodiversity and ecosystems of Ciric. Additionally, the organizations have highlighted the social and physical benefits of the area for residents, including flood regulation and prevention, pest control, provision of clean air, and recreational and scientific opportunities.
To further raise support and awareness for their efforts, SOR and Civica conduct guided tours, educational workshops, and photographic exhibitions. They have also set up two informational panels in the area that highlight the biodiversity of Ciric. Furthermore, the two NGOs have partnered with regional organizations to create the "Rețeaua națională de arii naturale urbane" (The National Network of Urban Natural Areas) and have received funding from the EEA Grants.
