There is no other region in Central Europe that is so rich in special features and evidence of thousands of years of extraordinary natural history in such a small area. The Mainz Sand landscape was formed around 10,000 years ago and is therefore relatively young. Dunes were formed by drifting sand that was blown out of the gravelly riverbed of the Rhine. The emergence of trees and shrubs stabilized these dunes, essentially completing the dune formation process. The resulting landscape is very rare, as these are inland dunes. Due to the sparse vegetation and human intervention, which repeatedly created open spaces, shifts continued to take place, so that the youngest dune formations are barely more than 50 years old. And it is precisely these constant shifts that are a decisive ecological factor determining the extraordinary flora and fauna.

The flora of the Mainz Sand is internationally renowned. Vegetation that is now found far to the east or south was able to establish itself here due to the special characteristics of the location. The dry regional climate and the sand do not provide favorable conditions for forestation, and humans have also curbed the spread of trees and shrubs through their use of the land. This has allowed plants that require light and warmth, which are more commonly found in the Orient and Occident, to thrive and become native to the area. Along with the plants, animals that are otherwise rarely encountered and depend on the vegetation have also settled here. Many of the species found here are protected and are very rare in Germany.

This area is also important for local recreation, as the Mainz area is densely populated. The paths that lead through the Mainz Sand invite you to take long walks or go for a jog.

But this is where problems arise: if people stray from the paths, the sensitive areas are damaged by trampling. Cross-country running not only damages small animals and destroys the original vegetation by trampling or breaking it, it also promotes plants that are not affected by this impact. This can lead to the displacement of native plants, and the resulting compaction also hinders germination.

Another problem is noise pollution, which mainly affects bird life. As a result, several bird species have disappeared from the area in recent decades.

Another significant problem is the change in the chemical properties of the soil. Above all, the accumulation of nitrogen leads to the growth of non-native species. Normally, the prevailing sandy soil is extremely nutrient-poor, allowing specialized species to grow here. Due to the lack of nutrients and the dry conditions, they are small and grow slowly. However, if nitrogen in particular is introduced into the area, large-leaved and fast-growing plants can also germinate and displace the native vegetation.

To protect the area and its native flora and fauna, we therefore ask you to stay on the marked paths. Please do not let your dog run free and remove any waste left behind by your four-legged friend. The flora and fauna will thank you for it!
