Shrub Hedge and Biodiversity at Ferme des Marnières (Lasne)

Alexandre aims for large-scale projects to promote biodiversity around his market gardening activity. In this project, we aimed for 573 meters of hedges, or approx. 1,957 plants to be planted. All the elements are in place to recreate shelter, cover, and wildlife corridors on the Lasne side. You strengthen biodiversity and contribute to soil carbon sequestration. Finally, the hedge ensures the preservation of soil and water quality.

Installation of 573 meters of hedge

Alexandre recently launched his agroecological project on a 9.8 ha plot in Lasne. Delicious vegetables are currently being cultivated there. Far beyond what the organic label requires, various virtuous practices are being implemented: living soil market gardening (permanent soil cover, massive input of organic matter, absence of plowing, etc.), agroforestry (combining orchards and market garden crops), and the establishment of hundreds of meters of hedges and flower strips (combating erosion and stimulating biodiversity). In total, the plantings represent 1,248m (single – double and triple rows) across the entire plot).

The first meeting with Alexandre took place in August 2023. We took the time to listen to his concerns, to determine the desired linear arrangements and functions of the hedge:

  • strengthen the ecological network on his farm with perimeter hedges,
  • to promote a host of active auxiliaries against pests,
  • to combat the problem of soil erosion
First site visit with Alexandre and Yago – the groundwork was laid.

Hedges: an ecological and nourishing corridor

Hedge planting using mechanical augers – bare-root plants.

On February 12, 2024, the linear plantings were carried out after a period of intensive rain. The plants were marked with blue Sema marking paint to protect them from rabbits.

The hedges are composed of a mix of hawthorns, medlars, hazelnut trees, dogwoods*… A mix of more than 15 different species of native trees and shrubs have now been planted.
