Lady Park Wood National Nature Reserve
Lady Park Wood National Nature Reserve () is a nature reserve straddling the borders of Gloucestershire in England and Monmouthshire in Wales. Most of the wood is in Wales but it is managed under agreement with Natural England.〔(Countryside Council for Wales information on Lady Park Wood NNR )〕
The wood is in the Wye Valley Area of Outstanding Natural Beauty. It is part of the Upper Wye Gorge Site of Special Scientific Interest (SSSI) and the River Wye Special Area of Conservation (SAC). The site is privately owned and access is on recognised rights of way. Permits are needed to access non-public areas. The wood has been a research location for some time as unmanaged woodland and is a prime woodland conservation area.〔〔 It is notable as being the eastern-most point of Wales.
==Location and habitat==
The reserve is considered to be one of the most important sites for woodland conservation in the United Kingdom and lies on the southern side of a gorge formed by the winding River Wye.〔 Located half way between Monmouth and Ross-on-Wye, it is part of the long stretch of woodland which fringes the lower part of the Wye Valley and then joins the Forest of Dean. The nearest community is Symonds Yat.〔(Natural England description of Lady Park Wood NNR )〕
In response to criticism of its afforestation programmes in 1938, the Forestry Commission offered ecologists the opportunity to set up research reserves on its land. With the support of Eustace Jones of the Oxford University Forestry department, the only such reserve that was established in the UK was at Lady Park Wood. The reserve was established in 1944, and has been surveyed on a regular basis since then. In 1945, the wood consisted of old stands that had been coppiced in 1870 and thinned in 1902 and the 1920s. All were then allowed to grow unmanaged. According to ecologist George Peterken, it was found that tree growth led to a decline in tree numbers, through increasing shade and browsing by deer, and, over time, disturbances such as Dutch elm disease in the 1970s, and a late snowfall in 1983 had increasingly disproportionate impacts on the woodland. It was found that "there was no single natural composition; rather, the natural mixture would fluctuate between beech dominance and ash-lime dominance according to the chance impacts of various disturbances." In recent years the woodland has become overrun by fallow deer and grey squirrels — both non-native species — affecting the regrowth of its trees.
