2.1 Short description of the Technology

Definition of the Technology:

Low-maintenance hedgerows were established in 2003 at the ridges of an agro-pastoral farm common in Brittany to protect water quality, ensure animal well-being, maintain biodiversity, and for energy, timber and litter production.

2.2 Detailed description of the Technology

Description:

Brittany is an area in the north-west of France. Brittany’s agriculture includes well-known products such as: fish, beef, pork, poultry, vegetables and milk. The technology is applied at Danilo Noël farm, located in the commune of Mauron in Morbihan. The region has an average annual rainfall of 650-700 mm and annual temperature of around 11°C. The climate of Mauron is warm and temperate, with the farm located in the basin known as Ploërmel. ‘Bocages’ in France refer to small forests and decorative elements such as hedgerows or ornamental garden structures that border agricultural fields .

The fields of the Danilo Noël farm are grouped together in a rotational system of fodder crop and short-term pastoral leys, divided into fenced paddocks. They are located between two ‘talwegs’, with slopes of 5 or 6 %. An analysis carried out in 2000 by the water management organization ‘Grand Bassin de l'Oust’, shows that 85% of the plots are at high and medium risk of plant protection product runoff due to the slope and water run-off.

Following this evaluation of the farm, the ‘Bocage’ (small hedged pasturelands) was developed starting during the winter of 2003/2004, with the planting of 800 meters of woody features (hedges and trees) along the slopes of the talweg. Other slope plantings were carried out on the edge of the paddock in 2014/2015 (1500 meters) and 2018/2019 (1650 meters).

Earth bunds were established along the contour, either with a shovel (in 2003 and 2014) or with a forest plough (in November 2018), with hedge and tree whips (1-2 year old growth) planted 1 meter apart in single rows diectly into the shovel or plough furrow and a small amount of fertiliser and wire tree guards added. There was no irregation installed.

The technology was applied in three differnt phases combining to form one overall long-term plan. The tree species chosen for the hedgerow are local species (oak, beech, cherry, birch, myrobolan plum, chestnut, hazelnut, etc.). For the last two phases of the programs (2014 & 2018), emphasis was placed on the presence of melliferous species (for honey production) and the spread of flowering species (fruit trees, burdock, blood dogwood, medlar, etc.).

Buffering of fields with hedgerows aims to protect surface water quality and prevent land degradation by slowing surface water runoff and hence reducing soil erosion, nutrient and plant-protection product (pesticide) export and improving water infiltration into the soil and groundwater recharge. The reduction of soil erosion in turn improves productivity with a better surface cover and nutrient retention for improved plant establishment and growth. Additionally, maintenance and/or improvement of biodiverstiy can be attained as well as providing shelter for animals supports their well-being.

Major activities of the technology include: Tipping of trees (old and new) in spring/summer, soil preparation at the site of the future hedge in autumn and creation of the embankment (earth bund along the contour), tree planting over winter and laying of mulch and installation of game guards.

Benefits of the hedgerows/ shelter belts are reorganization and improvement of the field to reduce flooding, protect water quality , improve welfare of the livestock, Increase biodiversity of wildlife, including insects, birds and game. Additional honey bee forage supported the installation of an apiary (18 colonies) by a professional beekeeper in May 2019.

The only weakness of the technology in the eyes of the land owner was the extra cost/workload associated with the maintenance of the hedgerows.

The compilation of this SLM is a part of the European Interreg project FABulous Farmers which aims to reduce the reliance on external inputs by encouraging the use of methods and interventions that increase the farm’s Functional AgroBiodiversity (FAB).

Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view	How can they be overcome?
Time intensive upkeep (i.e. training of saplings) that maybe overlooked and thus not produce highest quality output	Outsource labour work (yet additional expense)
Lack of outlets for wood from hedgerows	- self-consumption of wood: installation of plate boilers on farms, or heating networks, use of wood for animal bedding - developing territorial channels for the valorisation of wood from hedgerows
Need for training and support for operators	Sustainable management plan for hedges and trees on the farm, and monitoring.
