National Forest Species Trial (Church Gresley 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立，旨在探究44种原生及非原生树木物种在低地不列颠多种不同场地类型上的定植与早期生长（至14岁）情况。在优质低地造林场地上，杂交种白杨（Platanus x hispanica，又称伦敦杨）相较于本土树木表现出更成功的定植与生长，这或许是一个理论上能够预见未来气候变化而提前定植的物种实例。在各种社区林地场地的实验表明，诸如X Cupressocyparis leylandii（莱兰松）等一类外来物种，在土地修复较差且其他树木难以生长的贫瘠土地上，可能具有建立林地覆盖的潜力。然而，在修复状况较好、挑战性较低的土地上，众多本土物种也实现了成功的生长。为进一步确认这些物种在英国条件下的潜在适应性，需要进行长期且更大规模的多种场地试验。这些实验的结果还显示，不同物种的相对生长速率会随时间变化，这突显了仅基于树木早期生长的非常早期判断物种适宜性的危险性。另见：Willoughby, I., Stokes, V., Poole, J., White, J.E.J. 和 Hodge, S.J.
