Freiburg Invests in Biotopes – New Plan for Biodiversity in the Black Forest

The Biotope Network as a Key to Biodiversity

The city of Freiburg has established itself in recent years as a pioneer in environmental and climate protection. In January 2026, it set another important milestone with the adoption of the new Freiburg-Black Forest Biotope Network Plan. The plan aims to secure and long-term increase biological diversity through the creation of a functional biotope network. Covering over 15,300 hectares in the municipalities of Kappel, Ebnet, and Freiburg, this is an ambitious project of regional significance and also holds importance on state and federal political levels.

Concrete Measures for the Conservation of Habitats

The Biotope Network Plan contains a variety of measures aimed at the conservation and development of natural habitats. One of the central measures is extensive grassland use, particularly in the form of mowing and sheep grazing. Approximately 180 hectares will be restructured over the next few years in this way to support species such as grasshoppers and butterflies.

In addition, measures for maintenance and replanting of scattered orchards are proposed to preserve the traditional fruit gardens in the suburban areas. Also planned are actions for forest edge design, which aim to enrich the open forest edge with shrubs and structural diversity. These measures are not only important for animal and plant species, but also for the stability of the regional ecosystem.

Another focus is the care of dry-warm structures, which are of central importance for specific species such as the skylark or the natterjack toad. In the southern part of the planning area, even a minimum area concept has been developed to ensure the openness of Black Forest valleys. This not only accounts for biodiversity, but also for touristic and climatic benefits.

Cooperation and Funding as Success Factors

The implementation of the Biotope Network Plan is a collaborative effort between the city, land users, property owners, and nature conservation associations. A central role is played by the newly appointed Biotope Network Ambassador, who advises land users and mediates planning on site. This person serves as a link between the various stakeholders and helps with the practical implementation of the measures.

Financially, the plan is strongly supported: The development of the Biotope Network Plan was funded 90% by the state of Baden-Württemberg. The total costs amounted to approximately 108,000 euros, with the state contributing about 97,000 euros. Farmers can receive subsidies of up to 90%, and municipalities up to 70%, which significantly facilitates the implementation of the measures.

Target Species and Connectivity as Central Planning Elements

The Biotope Network Plan is not only a collection of measures, but also a target-oriented concept aimed at the conservation of 25 endangered animal species and one plant species. These include bats, birds, amphibians, reptiles, dragonflies, grasshoppers, butterflies, beetles, and the yellow-bellied toad. The planning also takes into account spatial connectivity through so-called network axes, which are intended to improve the habitat for field birds and shrubland migrants.

Currently, the significant habitats account for about 23% of the open land area. With the implementation of all measures, this share could increase to 41%, which would represent a significant gain in biodiversity. The measures are detailed in fact sheets and plans for 9 key areas and are available online at freiburg.de/biotopverbund.

Outlook: A Model for Other Cities?

The Freiburg-Black Forest Biotope Network Plan is not only a local project, but an example of sustainable biodiversity policy. With its combination of professional planning, public participation, and financial support, it offers a replicable model for other municipalities. The implementation of the measures is monitored and continuously adjusted to achieve long-term results. In a time when biodiversity is declining globally, Freiburg is a pioneer in climate and environmental protection with this project.
