Nature conservation

Minimaliseren
  1. We participate in the Bern convention Group of experts of the amphibian and reptiles. We prepare and update Red Data Lists.
  2. Conservation aims and distribution limit analysis of areas designated by the Habitats Directive for such species as the Great Crested Newt (Triturus cristatus).
  3. The Life Ambition Project. The aim is the development of viable meta-populations of five amphibian species named listed in Annex II (and Annex IV) of the Habitats Directive (Great Crested Newt (Triturus cristatus), Yellow-Bellied Toad (Bombina variegata), Midwife Toad (Alytes obstetricans), European Tree Frog (Hyla arborea) and Common Spadefoot (Pelobates fuscus)).
  4. Habitat restoration projects, e.g. “Vipera verbindt...” (Vipera connects) and “Oases of Biodiversity”. Many of the restoration sites are Natura 2000 sites, which form a European network of protected areas for habitat and species conservation. The project “Oases of Biodiversity” is linked with the European Pond Conservation Network.
  5. We also coordinate national and provincial conservation plans, such as species-specific conservation plans for the Common Tree Frog, Common Spadefoot (Pelobates fuscus), Yellow-Bellied Toad (Bombina variegata) and Midwife Toad (Alytes obstetricans).
  6. Breeding programmes of species that are (critically) endangered in the Netherlands, such as the Common Spadefoot (Pelobates fuscus) and Fire Salamander (Salamandra salamandra).
  7. SOS Fire Salamander. Following the dramatic decline of the Fire Salamander (Salamandra salamandra), an action plan has been launched to try to prevent the species from becoming extinct in the Netherlands. This entails a nationwide publicity and fund-raising campaign, and field work and laboratory research being carried out to look for the cause of decline; the surviving individuals are being kept in a place of safety. 
  8. What are the effects of artificial light on nature? The University of Wageningen (WUR) has been looking into the impact of artificial light on flora and fauna (www.lichtopnatuur.org). The first results appeared in 2015. RAVON is contributing by observing the effect of street lighting on amphibians, especially toads, during their spring migration. After three years of observation it is clear that street lighting does affect the toads but not in the way we expected. The Common Toad avoids sections of roads illuminated with white or green light, but not those with red light. Moreover, when they encounter light, the toads stop moving. These findings can be used to help keep down the number of traffic victims.
