Summary
[edit]
| Description |
Français : Photo ancienne (fin des années 1980) d’une vaste étendue de landes à bruyère (Bruyère centrées = Erica cinerea principalement sur cette partie relativement sèche). On distingue les arbres qui faute d'herbivores (quasi disparition des lapins à cette époque, et abandon du pâturage) commencaient à envahir la lande. La partie visible au premier plan est très sèche, probablement en raison du drainage induit par sa situation extrême au dessus des flancs du plateau.
Lieu : Partie Ouest du Plateau d’Helfaut, dans la partie ouest de l’actuelle Réserve naturelle des Landes d'Helfaut (l'une des anciennes « réserves naturelles volontaires » , devenues depuis « réserves naturelles régionales ») de la Région Nord/Pas-de-Calais et l'une des quatre de ces réserves mises en place en guide de mesure compensatoires à la fragmentation supplémentaire du plateau d'Helfaut pas la VNVA (Voie nouvelle de la vallée de l'Aa) plus souvent nommée « Contournement d'Heuringhem ». English: Old photo old. (Late 1980s) : vast expanse of heather moorland at Erica cinerea focused primarily on the relatively dry ground.
Location: Western Part of the “Plateau d’Helfaut”, on the border of the current Nature Reserve Landes of Helfaut (one of the old "voluntary" nature reserves, "since become regional nature reserves") in the Region Nord/Pas-de-Calais and one of four of these reserves established in compensatory measuring against the ecological fragmentation effect of the new big road cutting the plateau Helfaut (Natura 2000, Arrêté prefectoral de Biotope). |
