Clearing out invasive alien species and allow natural regeneration maintaining the functionality the ecosystem

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.

Across Detroit, neglected properties and vacant lots are a common sight (1). Nearly three-quarters of Detroit residents report that there is currently deterioration—defined in the survey as a building or property visibly declining due to long-term neglect—in their neighborhoods (1). One organization, Rescue MI Nature Now, a Michigan nonprofit, is dedicated to transforming these neglected areas into beautiful, functional spaces that benefit both people and wildlife (2).
In 2022, the organization purchased property from the Detroit Land Bank that was marked for demolition (3). Following extensive renovations, the building—now named the Innovative Youth Studio—has become a hub for multiple community initiatives. These include a community garden across the street, a culinary studio that teaches young people how to prepare nutritious meals, a pollinator studio that educates on the critical role pollinators play in the food chain, and a hydroponic studio where plants are grown using nutrient-rich water instead of soil (3).
The pollinator project, developed in partnership with the U.S. Fish & Wildlife Service, supports small bee colonies by planting areas with trees, flowers, and native plants (2). To further enhance biodiversity and support butterflies, bees, and birds, Rescue MI Nature Now partnered with Bowling Green State University to gain insights into pollinator biodiversity and habitat potential (2). Through this initiative, the organization aims to raise awareness about pollinators, highlight their positive impact, offer guidance on creating pollinator-friendly spaces at home and enhance the quality of life for local residents and communities (2).
Additionally, the organization runs a Sustainable Youth Stewardship Program, where young people learn to garden, grow trees, identify various plants and invasive species, and practice conservation skills such as creating pollinator habitats and managing community gardens (3).

The Waliwa project, launched in 2017 by the municipality of Sainte-Luce, is a collaborative effort dedicated to restoring marine biodiversity, enhancing the ecological balance of the bay area, revitalizing the local ecosystem and supporting sustainable economic activities. By focusing on marine biodiversity conservation, Waliwa addresses several critical environmental challenges. The project helps mitigate coastline erosion, support the blue economy through artisanal fishing and tourism, and foster an environmentally friendly culture among the local community.
So far, the Waliwa project has implemented three initiatives: it restored the Gros Raisin backshore to address erosion and provide nesting sea turtles with protected space (Ref 4). The project also intervened to restore the Pont Café pond, which was covered in Salvinia Molesta, preventing the intake of oxygen and hampering its role as a water filter, habitat for species and flood regulator .
Furthermore, the project has conducted studies and raised awareness about the challenges posed by wastewater management on the health of municipal water bodies. Through these efforts, Waliwa is working to create a more sustainable and resilient marine environment for future generations. (Ref 4, 5, 6; 12)

Booterstown Marsh, the only remaining saltmarsh on the south shore of Dublin Bay, plays a crucial role in the Dublin Bay Protection Plan. As part of South Dublin Bay's protected landscape, this unique 4.3-hectare brackish water marsh provides vital environmental and educational value within an urban setting. It supports three key habitats, ranging from freshwater to saltwater, creating essential feeding and roosting grounds for an array of migratory birds. The marsh attracts numerous bird species, including Moorhen, Reed Bunting, Sedge Warbler, Teal, Snipe, Lapwing, Oystercatcher, Redshank, Dunlin, and Brent Geese, establishing it as the only bird sanctuary in South Dublin Bay.
Booterstown Marsh’s ecological significance is underscored by its inclusion in the Dún Laoghaire-Rathdown County Council’s Biodiversity Action Plan 2021-2025: Nature Recovery, Restoration & Reconnection. Managed by the Biodiversity Section of the council, this initiative focuses on protecting and enhancing Booterstown Marsh as part of a broader effort to restore natural habitats across the area. The council’s project addresses key factors in biodiversity loss—such as land use pressures, climate change, and invasive species—by implementing an annual monitoring program to prevent deterioration of critical EU Annex habitats and species.
An Taisce, a local NGO has managed the marsh reserve since the 1970s, dedicating efforts to conservation and public education. This habitat, along with other local ecosystems like the wetlands at Ballycorus and woodlands at Loughlinstown, serves as an essential natural defense against climate change, removing carbon dioxide from the atmosphere and helping stabilize local landscapes by slowing floodwaters in catchment areas.(1-6)

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).

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.

This initiative focused on creating a management plan for the Uricani forest, a protected area located near Iasi. Designated as both a nature reserve and a Natura 2000 site, the forest is crucial for its "Dacia oak & hornbeam forests" habitat and the presence of the stag beetle, the largest beetle in Romania and Europe.
Despite existing nature protection designations, the environmental NGO "Asociația Ecoturistică Prietenii Pădurii Bălțătești" recognized the need for an updated management plan. With European funding, the NGO developed a model plan for protected areas in Neamt and Iasi counties, including Uricani forest.
The NGO conducted monitoring activities in cooperation with forestry directorates to assess habitat conditions and stag beetle populations. The goal was to identify risks and requirements for species conservation and design appropriate management actions. Additionally, the organization aimed to promote the area's tourism potential and conduct awareness-raising activities with local communities and schools.
The completed management plan, developed through public consultation and approved by the Romanian environmental ministry, included measures for natural habitat regeneration, ensuring suitable conditions for the stag beetle, addressing illegal logging, pasturing, and waste disposal, and establishing information points and educational activities for the community.

In the bay of Fort-de-France, mangroves cover nearly 1,300 hectares, representing about 70% of the total mangrove area in Martinique. This plant formation, characteristic of tropical marine environments, is essential for the ecological balance of the bay. Mangroves act as filters, purifying marine and river waters, protecting the coastline against erosion, and providing habitat for various marine flora and fauna.
However, this fragile ecosystem is threatened by wave-induced erosion, urbanization, the spread of invasive species, and pollution. In response to these challenges, the French Coastal Protection Agency (Conservatoire de l'espace littoral et des rivages lacustres, CELRL) and its partners have launched an initiative to restore several mangrove areas as part of the “Contrat de la Grande Baie de Martinique" which is a collaborative initiative aimed at the sustainable management and restoration of the coastal and marine environment of the Greater Bay of Martinique. This contract typically involves partnerships between various stakeholders, including government agencies, local municipalities, environmental organizations, and community groups. The project identified several sites totaling 3.81 hectares in the Greater Bay area that require reclamation.
The project aims to restore mangrove populations by creating favorable conditions through actions such as clearing invasive species and trash, followed by replanting with white, black, or red mangrove seedlings, depending on the environmental characteristics of each site. Additionally, the initiative seeks to engage the public and youth through volunteering days and awareness campaigns (Refs 1-9).

The riparian forest of Montgérald, through which the “Monsieur” River flows, is located within Fort-de-France and boasts rich biodiversity, featuring around 100 species of shrubs and trees and about 30 animal species, including 16 types of birds. It is one of the last remnants of the mesophilic forest type and the only example in a French peri-urban setting. This unique ecosystem is recognized as a Natural Area of Ecological, Faunal, and Floral Interest (ZNIEFF) and a Classified Wooded Area (EBC), underscoring the need for conservation efforts.
Covering nearly 21 hectares, this site offers ecological benefits like air quality improvement and temperature regulation, providing a "fresh air island" near the city center. However, it faces significant challenges, including flooding caused by climate change and heavy rains, which exacerbate erosion along the Monsieur River. The area is also threatened by invasive alien species, making conservation measures even more crucial.
Since 2015, the municipality of Fort-de-France, along with project partners, has been working on developing this natural space for both conservation and public engagement purposes. The most recent actions occurred in 2020, including riverbank restoration, clearing invasive species, and creating walking paths and educational installations. Additionally, the project features an awareness campaign targeting local schools. The ongoing initiative aims to merge biodiversity conservation with community recreational use and environmental education, ensuring the resilience of this vital ecosystem against the impacts of climate change.
