The
Audomarois Marsh
If the management of water explains here almost all the landscape, its methods generated extremely different horizons. The Western fringes, around Large Broad, present a landscape touffu, where the willow tadpole abounds, where small farms advance far, in water. The central parts more recent and drained in XIXème century by the drainage works, offer on the contrary a landscape of opened truck farming, strongly structured by the rigorous network of the water gangs delimiting the lègres ground. Elsewhere, the exploitation of the peat bequeathed us vast ponds offering an invaluable refuge to a rich avifauna. The channel of Aa and the railway, elevated works underline the geometry of the marshes while stopping the sights and by reinforcing kind the density, the prégnance of the landscape. The constraints which the medium still imposes on the human practices however make marsh a preserved ground of road infrastructures, furrowed by the bacôves, spanned by the links and protected from the flood by simple valves...

Slopes
of Saint-Omer
In full heart of the Park, the slopes of Saint-Omer form a bracket of calms in the medium of very dense landscapes. The flexible undulations of the small valleys give its breathing to a plate largely dedicated to the cultures. Thus, the vastness of the fields forms a vast square for the valleys dry length whose are coiled villages and roads, fixed between the yellow and green lines of the curtains limestones and the slopes. The R.N. 43 stops this landscape, since which in the distances, the hillocks of Clairmarais and Watten announce the proximity of the marsh and the Mounts of Flanders.
The agglomeration audomaroise
Centered around the pivot of the hillock on which was established Saint-Omer, the agglomeration is organized beyond the old ramparts of this fortified town which verticalisent monuments and arrows Gothic. Each one of these old suburbs, become cities, car its structure of the landscape which it introduces. Alignments of houses of market-gardeners of the High-Bridge are the place of a decoration whose back opens without transition on the marsh. Longueness and Arch, on the other hand, announce the input in the paper valley of Aa and decline along roads traced well on the slopes an often remarkable industrial architecture (ship lift of Fontinettes).
The valley of Aa
Center old urbanization, the valley of Aa draws its originality not only from its industrial architecture, punctuated of old elements (large farms, water mills), but also of the honest opposition between its two slopes. The cities organized along D 211, answer the enfrichées and dark slopes of the slope directed North. The paper mills and the careers are dominated by wood dense in the medium of which persist of interesting mediums of moors (plate of Helfaut). Between these two universes, Aa ramified in several courses is announced by the gardens, the parks and the meadows of the woodlands which accompany it.

The
High Valley of Aa
Lumbres opens a landscape in any point different from that of the urban and industrial valley. The relief is accentuated, affecting in the distances the aspect of imposing mounts. All seems to increase: the curtains limestones accomodate impenetrable coppices, wood and the forests crown the nodes, the agglomeration of Lumbres is spread on the slopes. One traverses the valley along sloping slopes, gullied dry valleys, where remain immense surfaces of piquetées calcicoles lawns genévriers. Composed well along the roads of cornice, the villages and the boroughs seem to be done discrete vis-a-vis with such an amount of majesty.
The Valley of Acquin
Running with the foot of a long ravine born of a fault, water irrigates funds of the woodlands here. Among the cut hedges, the villages agglomerate around the churches of tuffeau. The landscape thus contrasts in any point with that of the High plateau of Artois which dominates the ravine. While being inserted in the small valleys with let us fons wet, the landscapes ressere while the slopes are enfrichent. The forest gains soon the unit and one enters wood finally who give further on the Country of Licques.
The Valley of Hem
Hem circulates with the liking of its many meanders in a grazed content striated by the low hedges, punctuated by the old water mills and animated by the willows. This full depression is bordered by high reliefs carrying of imposing calcicoles lawns, themselves crowned of wood and forests. It results from it a very staged landscape, of which the roads, skirting the valley, form part carefully. Limestone dominates in the haloed villages of meadows and raised hedges which, established with semi-slope, offer view-points on the bottom of valley.
The wooded chain of the maritime Plain
Enclosing Aa at its entry in Calaisis, the hillocks which carry the forest of Eperlecques and the Wood of Ham in Watten form to some extent the septentrional gate of the marsh. There, between wooded mounts and wet grounds (marsh in the South, maritime plain in North), the boroughs and villages of Watten, Ruminghem and Muncq-Nieurlet offer a very marked meadow aspect. Beyond the timbered chain, to the foot of the village of Ruminghem, the wateringuée plain extends to the sea, whose horizon can be perceived since the hillocks.
