"Eh da"-areas are anyway available in the landscape or in villages. The ecological condition of “Eh da”-areas can be determined with adjuvant mapping in the field and then position specific arrangements which promote biodiversity can be generated. Especially the revaluation of the areas for pollinators and the interconnection of nesting and foot sites are important.
Beside of computer based acquisition the Ifa knows through perennial tests in semi-outdoor trials how to manage and enhance (nesting material like deadwood, seed mixtures) “eh da”-areas. With the help of the thereout developed “Praxisleitfaden” the IfA implements in Bornheim (Rheinland-Pfalz) and Derenburg (Sachsen-Anhalt) area specific revaluations. The IfA also presents from 04/17/2015 until 10/18/15 the “Eh da”-areas at the “Landesgartenschau Landau” in cooporation with the “Gartenakademie RLP”.
