De Razende Bol is a jewel in the collection of nature reserves managed by Landschap Noord-Holland. For a few years they have been responsible for nature management on this sandbar that is also known as Noorderhaaks. The sandbar is constantly under the influence of current and wind, the location is therefore constantly changing. The Razende Bol is slowly moving in the direction of Texel. Because this sandbar is regularly visited by holidaymakers in the summertime, Noord-Holland Landscape was asked by Rijkswaterstaat to supervise. The most important part is maintaining the peace and protecting the breeding birds and resting seals. The north side of the Razende Bol is closed to visitors for a certain period. No one comes to the sandbar for much of the year. Because it is so peaceful, it is a place where many birds stay. It is also a nice place for seals. There are common seals and grey seals, up to 350 individuals. Grey seals use the island to birth and suckle young. The animals need rest during the suckling time. Every disruption can mean disaster for a young pup, especially if its mother does not come back to suckle because of the disruption. Peacefulness on the Razende Bol is therefore very important.

Huisduinerpolder
The nature that surrounds Den Helder is fairly unknown, but certainly worth the effort. For example the "Huisduinerpolder". Located behind the hospital of Den Helder starts a path to the marshy polder, next to Fort Erfprins. The brackish influence of the North Sea water is noticeable in the vegetation due to the presence of salt-loving plants. In spring and autumn there are large numbers of curlews, sandpipers and oystercatchers at high tide. Brent geese, snow buntings and moorhens look for food in the winter. The polder is a breeding ground for reed singers and redshanks.
