90-560: A result, by the beginning of the 20th century, Bornholm had become Denmark's most forested region. Bornholm's highest point is Rytterknægten at 162 metres (531 ft), where there is a memorial to Frederick VII of Denmark and Countess Danner's visit to the island in 1851.

The site forms one of a set selected to ensure adequate representation of all species restricted to a given biome, both across the biome as a whole and for all of its species in each range state. The assessment by expert individuals

126-409: Is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International . There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In

144-618: Is completely lacking. In 1985, following a specific request from the European Economic Community , Birdlife International drew up a list of sites to be protected as a matter of priority. In 1989, a repertoire of IBAs of Europe was released. At first the official name of this type of site was Important Bird Area , hence the acronym IBA, then at the BirdLife World Congress held in Canada in 2014 it
