National Forest Species Trial (Bagworth Heath 1999)
Desford 4
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.

Non-native species were selected for their potential to establish a woodland cover and produce timber on difficult and degraded sites. The native species Q. robur was included for comparison. One- to two-year-old bare root plants were used, except for P. nigra which was cell grown. Stock was sourced from reputable supplies or grown from seed at Headley Research Nursery, UK (51° 08 ′ N, 1° 51 ′ W). Platanus x hispanica Münchh. (London plane) and Quercus x turneri Willd. (Turner’s oak) were not planted at Bagworth Heath until February 1995 and December 1995, respectively, due to supply problems. Trees were planted at 1.8 × 1.8 m spacing, and each 14.4 × 14.4 m plot contained 64 trees, with assessments carried out on all trees. There were three replicates of each of the 17 species, laid out as three randomized blocks, giving 51 plots in total. Acer campestre L. (field maple) was planted around any plot edges not abutting other treatments. Acer campestre was also used to replace any dead trees in all the species plots, to maintain conditions of even competition. Herbicides were used to keep a 1-m 2 area weed-free around each tree from April to August for each of the 5 years the experiment was maintained. Height (to the nearest 0.1 cm), stem diameter (to the nearest 0.1 mm) at 5 cm above ground level and survival were assessed after planting and at the end of each growing season. All species were native to the region except Acer saccharinum L. (silver maple) and Alnus incana (L.) Moench (grey alder) which were included for comparison. Two-year-old planting stock was used. Some stock was sourced from reputable supplies, some grown from seed at Headley Research Nursery, UK (51° 08 ′ N, 1° 51 ′ W). The site is described as: Planting date: April 1994 Elevation (metre above sea level): 136 DAMS: 13 WHC: 4 Continentality: 11 Annual average rainfall: 750 mm Annual average growing degree days: 1524 Annual average soil moisture deficit (mm): 155 Ecological Site Classification: NA Topography: Artifi cial plateau raised above surrounding level topography Underlying geological formation: Drift over Permo-Triassic and Carboniferous reddish mudstone Soil: Coal-washed spoil overlain by 15 – 40 cm of brown silty clay loam topsoil, pH 6.6 Previous land use and vegetation: Colliery spoil tip with low-grade restoration by land forming; fescues with 5% wild flower mix sown Protection: Rabbit fence, vole guards where necessary Initial site preparation: Fertilized with 600 kg ha − 1 of NPK and 600 kg ha − 1 of triple super phosphate; high levels of iron pyrites in spoil; coarse limestone spread at 12 tonnes hectare − 1 .
