The Rypark in Basel, Switzerland, is located adjacent to the Rhein River over the Restaurant Rypark but within a walled environment meant to keep the public out, but open to the scientific community. The “Trockenbiotop” or Dry Meadow Biotope is set within a sandy gravel substrate and is a test site for biodiversity.

Aramis and Linda Velazquez joined a city tour in September 2005 led by Nathalie Baumann, Dipl. BioGeografin, and after scaling the 5′ high wall, found a wild mixture of woody flowering shrubs, native grasses, sedums, thyme, perennials, graffitti and even bird wings.
