Summary edit

Description
Français : Flore du bord du Ciron vu du pont de la Trave sur la route départementale D 222, juste en aval du barrage hydroélectrique de la Trave. Ce pont est situé au nord-Est du centre de la commune de Préchac (Gironde, France). Ici l'eau a une couleur thé, due à des acides humiques apportés par le bassin versant après une période pluvieuse. Elle peut être plus opaque ou plus limpide selon la saison et les évènement météorologiques des jours ou semaines précédents. Le fond est rocheaux et caillouteux, avec des zones de dépot de sable. En aval de ce point plusieurs km du cours d'eau sont continuellement presque totalement sous une canopée, sous une forêt galerie, et parfois dans une gorge. Ces conditions maintiennent une eau plus froide et un milieu nettement plus frais que la moyenne régionale.
English: The Ciron seen from the bridge of the Trave on the road D 222, just downstream of the hydroelectric dam of the Trave. This bridge is located north-east of the center of the town of Préchac (Gironde, France). Here the water has a "tea color", due to humic acids provided by the watershed after a rainy period. It can be more opaque or clearer depending on season and weather events of the previous days or weeks. The bottom of the river is stony, with sandy deposits. Downstream from this point several kilometers of the river are constantly almost completely under a canopy (wilderness), in a "gallery forest", and sometimes in grooves. These conditions maintain cooler water and a significantly cooler microclimate than the regional average.
