After more than 50 years, the spadefoot toad has been rediscovered in the west of North Brabant, the Brabantse Wal. The spadefoot toad is an extremely rare and endangered amphibian species. In each of the five Dutch provinces where the species occurs, its areas over time have considerably diminished, so also in North Brabant.
In this province there are only three natural populations present (reintroductions excluded). The westernmost populations in the Netherlands were formerly on the Brabantse Wal. Here the spadefoot toad (Pelobates fuscus) was discovered at two sites in the past, east of Ossendrecht (1953) and Bergen op Zoom (1960). In both places, the species was only observed once. Due to the absence of observations it was assumed during more than half a century that it was extinct there.
