Species diversification can increase resilience of British forests if diversifying species are adapted to site, are genetically variable, and do not harm existing forests. However, this paper stresses that future use of ‘alternative’ species for diversification should be contingent on rigorous biological risk assessment, results from forestry scale trials, and the establishment of sustainable British seed sources.

Is the introduction of novel exotic forest tree species a rational response to rapid environmental change? A British perspective.
A suggested way for British woodlands to combat the problems they are facing due to climate change and exotic pests and diseases is to grow a range of novel exotic tree species. Here we examine the arguments for doing this in the context of British forestry where the objectives are either commercial timber production or conservation of biodiversity.
