Agroforestry can play an important role in delivering more tree planting on farms, improving climate resilience, enhancing carbon storage and climate mitigation and encouraging more biodiversity in our farming systems (ETAP 2021-2024).
Through evidence reviews and novel empirical research, this project will address key gaps in knowledge to support effective agroforestry policy and action. The identification of knowledge gaps is guided by a panel of stakeholders. Topics covered include a tree species guide for UK agroforestry and carbon modelling for agroforestry.
Expanding Agroforestry’ is a 2.5-year project which started at the end of 2022 as part of the Nature for Climate Fund.
We have produced a ‘Tree Species Guide for UK Agroforestry Systems’ which aims to provide an overview of the physical characteristics, environmental tolerances, silvicultural characteristics, and ecosystem services and disservices, for a selection of 33 species of trees and shrubs that could be planted in UK agroforestry systems. It was produced by the University of Reading and Forest Research in partnership with Defra and the Expanding Agroforestry project stakeholder group. More information can be found on the Expanding Agroforestry: A Tree Species Guide for Agroforestry in the UK project page.
Soil carbon and soil greenhouse gases (GHG) have been assessed at different agroforestry systems. Soil acidity, nitrogen availability, phosphorous and cations (calcium, magnesium and potassium) have been also assessed at the sites. At some sites, soil biodiversity has been also assessed including bacterial and fungal, mesofauna and earthworms’ communities. The agroforestry systems evaluated so far include shelterbelts, short rotation forestry planted on ex arable and grassland and silvopastoral systems.
An interactive database of priority and protected species and whether they would benefit or disbenefit from agroforestry expansion, has been developed and is currently being tested by a user group.
This ‘Tree Species Guide for UK Agroforestry Systems’ provides an overview of 33 species of trees and shrubs that could be planted in UK agroforestry systems.
