Community forest species trial (St Neots 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.

本研究设立了一系列树种试验，以探究英国低地地区44种本土与非本土乔木在多种立地类型下的定植与早期生长（最长至14年生）情况。
在优质低地造林立地上，二球悬铃木（Platanus x hispanica，伦敦悬铃木）的定植与生长成效均优于受试本土树种，可作为理论上可提前定植以应对未来气候变化的候选树种范例。针对多种社区林地立地的试验表明，包括莱兰柏（X Cupressocyparis leylandii，莱兰西柏）在内的一系列外来树种，有望在其他树种难以存活的修复不良地块形成林地覆盖。但在立地条件较好、修复程度更高的地块，多种本土树种同样可以健康生长。仍需在更多样化的立地类型上开展长期、大规模试验，以验证受试树种在英国本土环境下的应用潜力。
本试验结果还显示，不同树种的相对生长速率会随时间发生变化，这凸显了仅依据树木早期生长阶段就仓促判定树种适配性的风险。
