The area has been covered in largely beech forest for centuries, leading to the development of a rich flora. Botanically similar to South Jutland, common plants in the area between Skamlingsbanken and Grønninghoved include wax hat, low thistle and hawthorn. As a result of cattle grazing, growth on the lower part of the hill is kept in check but the top grows wild. Some areas are left to nature allowing blackthorn, hawthorn, roses, elder and other scrub growth to flourish, while others areas are maintained in order to preserve the fragile natural grasslands. The whole area is protected by the Danish Nature Conservation Act.
