The Leaning Hornbeams of the Boscs

SpeciesHornbeam

These two made an official remarkable-tree register on the strength of a pose. They are 8 to 10 metres tall, 75 to 90 years old, with trunks somewhere between 44 and 68 centimetres through at the base, which in a forest full of beeches twice their height is nothing at all. What they do is lean. Both hornbeams grew out over the Mare des Boscs and hold themselves at an angle above the water, and the register says so in plain words: le lieu et la forme des troncs en font un endroit superbe, the place and the shape of the trunks make this a superb spot. Hornbeam is the hardest timber in these woods, dense enough that it was the traditional choice for mill cogs and butchers' blocks, and it takes a lean like this without snapping. The pond sits inside a wider wetland the region lists for its nature value, so the walk in is quiet and wet underfoot in places. It is the longest approach of the Roumare trees on this page. Park at the rond-point de la Martel, follow the a la Biche forest road, then a small dirt path on the left opens into the meadow and the pond.

The line is our estimate of how much there is to see, not a measurement. Typical for this species where this tree stands; exact weeks shift with the year.

Mare des Boscs, parcelle 330, Foret domaniale de RoumareYou can recognise them by their trunks leaning out at an angle over the water rather than growing straight up. They stand together at the edge of the Mare des Boscs, off the a la Biche forest road.

Free, public ONF-managed forest, no restrictions. Waymarked as part of the official 'arbres remarquables' trail.

No public transport reaches the forest. By car: on the D351 between Canteleu and Sahurs, park at the 'rond-point de la Martel', walk the forest road 'a la Biche' between parcelles 297 and 322, take the second path on the left at parcelle 330; this small dirt path leads to a meadow and the Mare des Boscs.
