A preserved biodiversity

Our High Environmental Value certification recognizes years of work on the estate to promote biodiversity.

High Environmental Value Certification

In July 2017, beginning with the 2016 vintage, Château Fleur Cardinale was awarded High Environmental Value (HVE) certification. This is the most demanding level of a general environmental certification system for farming estates. It offers proof that biodiversity initiatives are truly integrated in our vineyards.


We have not used any chemical weed control for many years. We only treat our soil only by ploughing.


For certain plots, we sow several types of seeds between the vine rows. We use two different types of seed: the first is a mixture composed of rye, vetch and crimson clover. The second is a mixture of oats, vetch, alfalfa, sainfoin, red clover and trefoil. These crops restore nutrients to the vine. They limit erosion and soil compaction, improving the soil’s porosity and load carrying capacity. They also provide a refuge and food source, promoting macro fauna (earthworms) and micro fauna (bacteria, fungi).


We fight grape worms by using mating disruption. This method allows us to avoid using insecticides. We implant devices in the vineyards that emit pheromones imitating the substances the female moths release to attract males. Once the atmosphere is saturated with these pheromones, the males cannot locate the females and mating cannot occur. The pheromones are not dangerous for our teams and the wildlife wandering through our vineyards. These methods are organic-approved.


We allow our uprooted plots to lie fallow before replanting. These fallow fields limit erosion and the use of fertiliser, promote macro and micro fauna and produce a natural nematicide effect. They are sown with plants producing pollen or nectar (vetch, trefoil, sainfoin, alfalfa, etc.). The estate also features permanent natural uncultivated land.


In 2018 we began a partnership with a beekeeper, Les Ruchers de Lilly, to host 10 of their hives so that the bees can enjoy the blossoms of the acacia trees surrounding some of our plots.


We do not burn the vine shoots we cut during the winter. Instead, we shred them, replenishing the vines with the nutrients.


In addition to cherry trees and a small apple orchard that were already on the estate when we arrived in 2001, we have planted 7 varieties of fruit trees around the Château: apricot, peach, fig, plum, pear, cherry and nectarine. These fruit trees provide shelter and a food source for macro and micro fauna.
