Windsor Hill is a 61.8-hectare (153-acre) biological Site of Special Scientific Interest near Princes Risborough in Buckinghamshire. It lies within the Chilterns Area of Outstanding Natural Beauty, and it is featured in the Nature Conservation Review. A small part is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust, and access to this area requires a permit. [1] [2] [3]
The wood consists of an extensive tract of the Chiltern escarpment. It contains beech woodlands, scrub and chalk grassland. It is one of three extant British locations for the red helleborine orchid. [4] [5]
The beech woodlands incorporate communities characteristic of soils on the Clay-with-flints of the Chiltern plateau and the chalky deposits of the scarp slopes. Associated with the beech on the plateau are oak and occasional birch whilst on the slopes, the associated species are ash and whitebeam. Both even-aged and more mixed stands are represented, the latter typically with a shrub layer including gorse and honeysuckle on the plateau, and elder and hazel on the slopes.
On the plateau, brambles, bracken and rosebay willowherb occupy extensive patches, but a more mixed ground flora occurs between these, including creeping soft-grass (Holcus mollis), hairy brome (Bromus ramosus), tufted hair-grass (Deschampsia cespitosa), wood millet (Milium effusum) and wood melick (Melica uniflora). Pill sedge (Carex pilulifera), hairy wood-rush (Luzula pilosa) and slender St. John's-wort (Hypericum pulchrum) are found in more heathy areas, and the rushes Juncus effusus and J. conglomeratus are present in damper areas.
On the slopes dog's-mercury (Mercurialis perennis) and woodruff (Galium odoratum) are abundant, while more local species include nettle-leaved bellflower (Campanula trachelium), white (Cephalanthera damasonium), broad-leaved (Epipactis helleborine) and narrow-lipped (E. leptochila)helleborines, yellow bird's-nest (Monotropa hypopitys) and scaly male-fern (Dryopteris affinis).
Juniper scrub occurs on Windsor Hill itself, where it is associated with various other typical chalk shrubs and chalk grassland with an abundance of the moss Pseudoscleropodium purum and common valerian (Valeriana officinalis). There are patches of bare chalk with forget-me-nots (Myosotis species) and common mullein (Verbascum thapsus).
On Kop Hill, hawthorn dominates the scrub, and the grassland is less mossy. Several localised plant species such as squinancywort (Asperula cynanchica) chalk eyebright (Euphrasia pseudokerneri), horseshoe vetch (Hippocrepis comosa), autumn gentian (Gentianella amarella) and clustered bellflower (Campanula glomerata) occur. A further small area of chalk grassland dominated by wood false-brome (Brachypodium sylvaticum) and glaucous sedge (Carex flacca) occurs at the foot of Pink Hill.
23 species of butterflies have been recorded, including brown hairstreak (Thecla betulae), which requires scrub thickets and woodland edge habitats. The juniper colony supports several species of insects specific to this host plant. The snail fauna includes Abida secale , Helicella itala and Pomatias elegans .
There is access from Kop Hill Road and Peters Lane. [2]
Salisbury Plain is a chalk plateau in southern England covering 300 square miles (780 km2). It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire.
Beacon Hill is near the village of Burghclere and Watership Down, in north Hampshire. The hill's name is derived from the fact that it was one of many Beacon Hills in England and beyond. This hill was once the site of the most famous beacon in Hampshire. It is 261 metres high and has one of England's most well known hill forts on its slopes, visible from the main A34 road which passes close by. From there, outstanding views of the surrounding area and much of Hampshire may be obtained. The site is open to the public and managed by Hampshire County Council. It is an 80.7-hectare (199-acre) biological Site of Special Scientific Interest called Burghclere Beacon and a Nature Conservation Review site, Grade I.
Cephalanthera rubra, known as red helleborine, is an orchid found in Europe, North Africa and southwest Asia. Although reasonably common in parts of its range, this Cephalanthera has always been one of the rarest orchids in Britain.
Hawkley Warren is a woodland on the northeast-facing Wealden Edge, near the village of Hawkley, three miles north of Petersfield in Hampshire. The site is situated in a deep chalk combe.
Newtimber is a small village and civil parish in the Mid Sussex District of West Sussex, England. It is located north-west of Brighton. The parish also includes the hamlet of Saddlescombe. The parish lies almost wholly with the South Downs National Park, with the exception of a small section of the parish north of the B2117 road. The planning authority for Newtimber is therefore the South Downs National Park Authority (SDNPA), the statutory planning authority for the National Park area.

An area of 29.4 hectares is a Special Area of Conservation and an area of 10 hectares is a nature reserve owned and managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust (BBOWT). The site is well known for the variety of wild orchids that grow on its sloping grassland, and especially for the monkey orchid that grows in very few other places in England.
Bratton Downs is a 395.8 hectare biological and geological Site of Special Scientific Interest in Wiltshire, England, near the villages of Bratton and Edington, and about 3 miles (5 km) east of the town of Westbury. It was notified in 1971. The designated area consists mainly of chalk grassland, as well as some ancient woodland, and supports a diverse range of native flora and fauna. It overlays notable geological features—principally landforms created by glaciation in the Pleistocene.
Clayton to Offham Escarpment is a 422.5-hectare (1,044-acre) linear biological Site of Special Scientific Interest (SSSI) which runs from Clayton in West Sussex to Lewes in East Sussex.

The flora of the Vosges massif is distributed across three principal altitudinal zones, namely the collinean, montane, and subalpine levels. The collinean zone extends up to approximately 500 meters in altitude. The montane zone is between 500 and 1,000 meters, with the subalpine zone extending beyond that. The latter's highest point is the Grand Ballon, which reaches 1,424 meters. The diverse environmental conditions, including altitude, climate, topography, and soil types, contribute to the formation of heterogeneous vegetation. The north-south orientation of the mountain range results in a marked contrast between the eastern and western slopes. The western slopes receive abundant precipitation from westerly winds, while the eastern slopes and peaks experience drier conditions.
