Other Site Characteristics

Le site comprend la vallée de la Helle, ainsi que ses affluents, depuis le Grand Bongard, au nord de la Fagne Wallonne, jusqu'à sa confluence avec la Soor.

4.2 Quality and importance

La majeure partie de la réserve forestière du Bongard est englobée dans le site. Elle l'enrichit des hêtraies acidophiles (9110) du Brandehaag, extrêmement riches en bois mort, et des tourbières hautes dégradées (7120) ou boisées (91D0), des landes tourbeuses (4110) et autres habitats précieux des milieux tourbeux et paratourbeux du Grand Bongard.Cette vallée à la haute qualité biologique accueille les pics noir, mar et cendré, ainsi que la Cigogne noire. La présence de la Chouette de Tengmalm est également signalée, illustrant la richesse de ce site capable d'offrir des habitats bien spécifiques à des espèces aux exigences variées.
