Climate Match (UK)

At two sites plots have been planted, one in Derbyshire (central England) and the other in Kent (south-east England) in 2011. They serve as research-demonstration plots to test how various planting mixtures might contribute to improved resilience of native forests to climate change. Forest Research (UK) has matched the warmer, drier climate predicted for Derbyshire and Kent in 2050 with the present climate in northern France and the predicted climate for 2080 with that in northern Italy. Different ratios of local and non-local provenances are tested. The experiment will be monitored to identify the best mix of tree planting stock of each species for Derbyshire/Kent and how provenances from northern France and northern Italy interact with local wildlife, including their resilience to tree pests and diseases.

Design

The experiment is performed at two sites: Kent and Derbyshire. The only difference in design between the sites is the number of provenances planted: 3 in Kent, 4 in Derbyshire (the most northern plantation). Each site contains 3 blocks, i.e., replicates of the experiment setup. A block consists of 3 types of treatment plots: single-species single-provenance, single-species mixed-provenances, mixed-species mixed-provenances. In each block, the single-species plots occur as a series of randomly positioned plots (12 m x 12 m), in which 36 trees are planted. The single-species mixed-provenances plots consist of 2 provenances (50:50 or 75:25 mix, with the local provenance having the greatest proportion) or 3 provenances (33:33:33 mix). There is 1 mixed-species mixed-provenance plot (36 m x 32 m, 288 trees) in each block. The planting was done with 3 year old saplings, at a 2 m x 2 m planting distance.

Research

Research questions that will be addressed include: (1) Which planting stock of oak, ash, wild cherry and sweet chestnut is recommended for woodland establishment in the Midlands and southeastern Britain in the face of climate change? (2) What is the recommended planting ratio of local and non-local provenances of these tree species to achieve maximum survival and growth rates? (3) How does mixing local and non-local provenances affect stand structure and provenance performance? (4) How do non-native provenances affect associated biodiversity and the incidence of pests and diseases?

The following specific assessments of saplings are being done or planned: survival (post-frost, post-drought), growth (height, dbh), form (leaf area, branching patterns), phenology (e.g., bud-burst), and associated biodiversity (e.g., incidence of insect herbivory). When a canopy starts to develop, litter traps will be installed to provide information on the comparative biomass of flowers, leaves, and fruits. Local variations in temperature are currently being monitored at the soil surface.

The Derbyshire site was established in partnership with the National Forest Company and the Forestry Commission. The Kent site is jointly sponsored by the Forestry Commission and the European Union within the framework of two Interreg projects: the Management of Multifunctional Forests project (MULTIFOR) and the Forest Management Adaptation project (ADAFOR). MULTIFOR (2009-2013) was funded under the European Interreg IV A 2 Mers Seas Zeeën Cross-Border Cooperation Programme; ADAFOR (2013-2015) was selected under the European cross-border cooperation programme INTERREG IV A France (Channel) - England, co-funded by the ERDF. Land for planting the Kent site was provided by the Woodland Trust.
