Lahnstein to Renovate Pond, Enhance Biodiversity
In a bid to revitalize the Ernst-Wagner-Park, the city of Lahnstein is planning a comprehensive rejuvenation of its pond. This endeavor is supported by funding from the Zukunft - Umwelt - Gesellschaft (ZUG) gGmbH, with the goal of transforming the pond into a more natural and biodiverse habitat.
Established in the 1970s, the Ernst-Wagner-Park catered to a hotel complex, healthcare facilities, and local residents. The recently designated Kur- und Heilwald Lahnstein now adjoins the park, making it an attractive addition to the recreational area.
The pond, spanning approximately 3,600 m², has no natural water inflow and relies solely on rainwater. In November 2023, parts of the pond dried up, revealing a predominantly concrete-built bottom and edges. Despite the presence of fish, their habitat continued to diminish due to the water shortage, which was temporarily compensated through the introduction of raw water.
Aging infrastructure, such as deteriorated pathways, benches, and lighting, also needs renovation within the 23,000 m² park. The outdated design, modeled on the spirit of the 1970s, offers little contribution to biodiversity and does not meet contemporary standards for a natural recreational space.
To address these issues, the current pond will be dismantled and reconstructed as a natural, diverse body of water that draws water from dry streams. The revamped pond aims to attract various insects, aquatic life, and amphibians, supporting biodiversity and creating a more inviting ecosystem.
In addition to the pond, the park will be replanted with native vegetation, including wildflower meadows and perennials. Future maintenance will prioritize insect-friendly mowing techniques to encourage the growth and settlement of bees and other beneficial insects.
The expansion of the Kur- und Heilwald Lahnstein will incorporate new experiential areas, such as "Water and Wildflower Meadows." The park will prioritize accessibility, enabling all visitors to enjoy the natural surroundings.
Prior to renovation work, the remaining water from the pond was drained to safeguard the predominantly carp fish population. The fish relocation was overseen by the Rhein-Lahn district's Veterinary Department and executed by "Teichanlage Kern" employees. The fish were resettled in a suitable body of water.
The city of Lahnstein is preparing to issue a public tender for the planning services, with the award expected by mid-2025. Once the design plan is formulated, the public will be informed about the project, raising awareness about the importance of amphibian habitats and wildflower meadows, and demonstrating how climate-adapted planting promotes biodiversity.

When renovating a pond, the primary focus should be on wetland restoration and habitat creation. This process typically involves improving water circulation, planting native vegetation, and incorporating diverse aquatic features. Boosting biodiversity can be achieved by introducing native species carefully and maintaining a balance between predators and prey. Fish relocation is best carried out humanely, with minimal stress, before renovation work commences. Temporary housing for the fish may be necessary until the pond is ready for them to return.

- To support the enhancement of biodiversity, the city of Lahnstein is planning to transform the Ernst-Wagner-Pond into a more natural and diverse aquatic habitat, which will also include wildlife-friendly planting and infrastructure for insects.
- In line with the emphasis on biodiversity, the revamp of the Linda-Gay-Park, formerly known as the Ernst-Wagner-Park, will not only involve the reconstruction of the pond, but also the planting of native vegetation, including wildflower meadows, to attract various insects, bees, and other beneficial species.
- As part of the ongoing efforts to improve the Lahnstein recreational area, the city is also actively working to incorporate environmental science principles into their home-and-garden projects, such as the renovation of the pond, to promote a more sustainable lifestyle and positive impact on climate-change.
