Diverse Habitat Reconstructions in the Őrség National Park in Hungary

National Id
Site name
Csörnöc-Herpenyő river, Vas County, Nádasd village
There are three measures applied in the national park area primarily for nature rehabilitation, but all measures have water retention aspects. (1) Creating ponds in the forest where run off from forestry roads are collected. The main goal is to create safe breeding ground for reptiles instead of temporary sumps on the roads. (2) Re-vegetating shelterbelts (groves, wetlands) in agricultural land where 50 years ago these landscape elements were destroyed for agro efficiency reasons. (3) Building closures in the drainage channels to enable the flooding of the alder (Alnus) forest and wet meadow to improve their natural quality an important site in the ecological corridor along the stream Csörnöc.

Key lessons
Rehabilitation of habitats where the initial status is still remembered and the land is already publicly owned is a "low hanging fruit" to implement. EU funds have an important role to make these changes happen. While at the same time these good examples are the first but not sufficient elements to initiate similar changes in privately owned agricultural lands

Information on Ecosystem improved biodiversity
1st component: Collected run off in forest provide safe conditions for reptiles to breed - habitat provision. Flood security was not named among the services because the small scale of the sites.
2nd component, habitat mosaics in agricultural land provide habitat service, and amenity services. The nutrient reduction potential was not named.
3rd component the closure of the drainage channel provides stability to the wetland-forest ecosystem (amenities). It also enhances biomass production. Decreasing run off is obvious, but its scale is small in itself.
The site is an important element of the migration path along the stream †“ habitat services.
