National Forest Species Trial (Bagworth Heath 1999)

A series of species trials were set up to investigate the establishment and early growth (up to 14 years old) of 44 native and non-native tree species on a variety of different site types in lowland Britain.
On good quality lowland afforestation sites, Platanus x hispanica (London plane) established and grew more successfully than the native trees tested, and may be an example of a species that could
theoretically be established in anticipation of future climate change. Experiments on a variety of community woodland sites indicated that a range of exotic species, such as X Cupressocyparis
leylandii (Leyland cypress), may have the potential for establishing a woodland cover on poorly restored land where few other trees would grow. However, on less challenging, better restored sites,
a wide range of native species also grew successfully. Further long-term and larger scale trials on a wider variety of sites are required to confirm the potential of the species tested for British conditions.
The results from these experiments also showed that relative growth rates of different species can vary through time, highlighting the danger in making premature judgements about species
suitability based solely on very early tree growth.

一系列物种试验被设置以研究44种原生及非原生树木物种在低地不列颠多种不同立地类型上的建立和早期生长（长达14年）情况。在优质低地造林地，杂交种白杨（Platanus x hispanica）相较于本土树种，在生长和建立上更为成功，可能成为未来气候变化预期下建立物种的典型例证。在多种社区林地立地类型上的实验表明，多种外来物种，如莱兰松（X Cupressocyparis leylandii），在难以恢复的土地上可能具有建立林冠的潜力，而其他树木难以生长。然而，在较为适宜、恢复较好的立地上，广泛的本土树种亦能成功生长。为进一步确认测试物种在英国条件下的潜在适应性，需要开展更长期、更大规模的试验，涵盖更广泛的立地类型。实验结果亦显示，不同物种的相对生长速率会随时间变化，凸显了仅基于树木早期生长的早期判断物种适宜性的风险。参见：Willoughby, I.，Stokes, V.，Poole, J.，White, J.E.J. 和 Hodge, S.J.
