Audi Environmental Foundation supports the Preservation of Orchard Meadows in Neckarsulm

The orchard meadows in Neckarsulm are a valuable cultural heritage, sustainably protected and promoted through the project "Preserving and Shaping Orchard Meadows Together" (Steg:Geo). Initiated by the Audi Environmental Foundation, the project sees the collaboration of the Heidelberg University of Education, the city of Neckarsulm, and Audi apprentices, all working together to preserve the region's biodiversity.

At the official project launch in the summer of 2024, Mayor Steffen Hertwig and Audi Plant Manager Fred Schulze emphasized the importance of the orchard meadows for the region and highlighted the commitment of all partners. Using innovative technologies such as drones and satellite data, scientists from the university analyze the condition and vitality of the fruit trees to detect potential diseases early.

Following initial drone flights in the summer, the image data was processed using the Structure-from-Motion (SfM) method. This resulted in precise, rectified map images (orthomosaics), digital terrain models, and vegetation indices. Additionally, the Real-Time Kinematic (RTK) module in the drone allows for centimeter-accurate recording of the trees' locations. By linking this data with on-ground tree assessments, each tree receives its own identification number. This enables precise condition assessments, monitoring, and maintenance based on individual tree recognition.

Audi apprentices in Neckarsulm actively support the project, learning to use modern methods for monitoring and caring for the orchard trees. This hands-on experience raises their awareness of the importance of protecting valuable cultural landscapes and inspires them to embrace sustainability beyond their training.

In February 2025, a group of apprentices practiced tree pruning during a project day. Thanks to expert instruction on the use of pruning tools and the correct cutting positions by Günter Glaser, Deputy Head of the Municipal Depot, they were well-prepared to test their new skills in the field – successfully, as seen in the photos! Yesterday, Neckarsulm Plant Manager Fred Schulze and his management team also participated in a tree pruning course. Both groups gained fascinating insights into the ecological significance of orchard meadows, as well as the planting, pruning, and care of trees to maintain their health.

The goal of tree pruning is to shape an optimal tree crown and ensure early, consistent fruitfulness. The maintenance of orchard meadows plays a crucial role in this. These meadows are a defining landscape feature in Baden-Württemberg, which is why they were recognized as an "intangible cultural heritage" by the UNESCO Commission in 2021. They not only provide delicious, regional fruit but also serve as an important habitat for numerous animals and plants. Birds, bats, hedgehogs, insects, and spiders find a home here, contributing to ecological diversity.
