A practical workshop in which participants will gain a good understanding of how to design farm tree planting schemes and work in small groups to design agroforestry systems for a range of case study farms.
The session was set out as a hands-on workshop with everyone getting involved in designing an agroforestry system. Jo Smith from ORC presented some of the key design principles and considerations for agroforestry systems.
With everyone having a different vision of what agroforestry is defining agroforestry can be a difficult task. Jo described a range of systems some of which, although familiar, we may not initially recognise as agroforestry practices. Take farm hedgerows for example – woody landscape elements integrated into our farming landscapes which also provide a multitude of ecosystem service. The more conventional systems included The Woodland Trust and Sainsbury’s Woodland Eggs scheme where trees are planted to benefit chickens.
Jo emphasised the importance of managing interactions between system components and of designing in a way that enhances positive interactions while minimising the negative. With potential trade-offs it’s important to remember the system’s intended purpose. For example, is it to provide income diversity or to increase productivity?
The design process was then broken down into four elements for consideration: site characteristics, species selection and spatial and temporal arrangements; all of which determine the level of interactions between system components.
Split into three groups and each given a case study farm, participants designed their own systems using the Jo’s guidance. The case studies included arable, livestock and horticultural systems with some groups lucky enough to have the case study farmers there to help, although encouraged not to give away their actually plans for the sites!
For both the arable and horticultural systems alley width was a key point of discussion. How wide should the alleys be to allow for machinery access while keeping components close enough for positive interactions to occur?
The biophysical characteristics of the sites, such as aspect, ground conditions and access, underpinned numerous choices for all three groups and determined species selection and spatial and temporal arrangements. Species selection was also influenced by what agroforestry products would complement the current enterprises.
Finally, Hamish Thompson of the Woodland Trust covered the available grants for tree planting offered by the Woodland Trust and the potential opportunities presented by the Countryside Stewardship Scheme with its emphasis on national flood management.
The discussion that followed the presentations brought out the following points:
- There are many examples of agroforestry some of which, although familiar, we may not initially recognise as agroforestry practices.
- It is important to manage interactions: design in a way that enhances positive interactions while minimising the negative.
- Four design elements should be considered: site characteristics, species selection and spatial and temporal arrangements; all of which determine the level of interactions between system components.

This presentation will briefly introduce the main types of temperate agroforestry systems and give an overview of the key design considerations, including drivers and constraints, species selection, spatial and temporal arrangements and management. This will lead into the design workshop below.

Participants will have the opportunity to develop tree planting schemes for one of three case study farms; livestock, horticulture and arable.
