The Kovan Kaya natural landmark has been given a special status with the aim of preserving rare and endangered plant and animal species. This is one of only a few places in Bulgaria where the rock volcanic niches have become a nesting site of the griffon vulture, the Egyptian vulture, the black stork, as well as of numerous typically southern species such as the rock thrush and the rock nuthatch.
