The hedgegrow

A hedge or a hedgerow? A hedge typically refers to a closely planted row of shrubs or small trees, often trimmed and maintained to form a boundary. A hedgerow is a more diverse and natural planting consisting of a mix of woody shrubs, trees, wildflowers and grasses that serves a broad range of functions. One of our commitments is to increase the presence of ecological hedges composed of indigenous species of plants throughout our estate.

Why do we prioritize hedgerows of native (local) species? A native species is a plant that is adapted to the climate, wildlife, and vegetation of its surroundings. With a hedgerow of local plants, it is possible to maintain the ecosystem’s balance and contribute to the conservation of our region’s endemic and genetic legacy. We have started using cuttings or seeds collected from our wooded areas for hedgerow plant production to ensure their resilience and a perfect integration to their environment.

In this particular hedgerow you can find holm oaks, almond trees and field elms. Below these trees are bushes such as strawberry trees, native rose bushes and white mignonette. Wild carrots, sweet autumn clematis, and savory calamint spread throughout. This combination of plants, with its brambles and branches, its flowers and fruits, is an oasis of biodiversity.

A hedgerow serves many purposes.

For the vineyard:

The hedgerow is a rich source of beneficial creatures. It promotes organic pest management by attracting beneficial organisms that feed on the vineyard pests.
The hedgerow acts as a natural windbreak. Effective against the wind, this vegetative barrier also reduces soil erosion as it slows down water runoff.
The hedgerow creates a microclimate by providing shade, mitigating extreme temperature variations, and retaining moisture.

For the ecosystem:

The hedgerow shelters and feeds numerous animals. It provides refuge, food, and breeding grounds for birds, hedgehogs, lizards, spiders, and a wide variety of insects. The greater the diversity of plants in a hedgerow, the higher the diversity of its wildlife.
The hedgerow serves as a corridor for animals. By connecting wooded areas on either side of the vineyard, it acts as a pathway between natural environments for animals.
Trees and shrubs in hedgerows absorb carbon dioxide from the atmosphere and store carbon in the soil.

“Did you know?” The most wildlife-friendly hedgerow consists of at least 3 layers of vegetation. If you look closely at our hedgerow, you will find herbaceous plants near the ground, shrubs a bit higher up, and trees towering above.
