Weston Turville Reservoir
Weston Turville Reservoir is a 19 hectare biological Site of Special Scientific Interest south of Weston Turville in Buckinghamshire. It is owned by the Canal & River Trust, and the open water is leased to sailing and fishing clubs while the surrounding land is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust. The site is in the Chilterns Area of Outstanding Natural Beauty. The reservoir was built in 1797 to supply water to the Wendover Arm of the Grand Union Canal. Large areas now have a deep silt deposit but in the more open areas, fan-leafed water crowfoot, small pondweed and the European white water lily grow. The southwestern and southern parts have extensive reed beds and this is where water mudwort and orange foxtail are both found, both plants being rare in Buckinghamshire. There is a more varied flora in the southeastern part, with grey clubrush and lesser bulrush. The two chalk streams that flow into the reservoir pass through an area ...

Royal Yachting Association
The Royal Yachting Association (RYA) is a United Kingdom national governing body for sailing, dinghy sailing, yacht and motor cruising, sail racing, RIBs and sportsboats, windsurfing and personal watercraft and a leading representative for inland waterways cruising. History The ''Yacht Racing Association'' was founded in November 1875. Its initial purpose was to standardize the rules of measurement to different racing yachts so that boats of different classes could compete fairly against each other. Membership at the time cost two guineas and was available to "former and present owners of racing yachts of and above 10 tons Thames measurement and such other gentlemen as the committee may elect". In 1921 the YRA incorporated the independent Sailing Boat Association and the Boat Racing Association into its body. In 1952 the YRA became the Royal Yachting Association (RYA). The RYA remains constituted as a membership association, with a Council of elected volunteers as its sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Shoveler
The northern shoveler (; ''Spatula clypeata''), known simply in Britain as the shoveler, is a common and widespread duck. It breeds in northern areas of Europe and across the Palearctic and across most of North America, wintering in southern Europe, the Indian subcontinent, Southeast Asia, Central, the Caribbean, and northern South America. It is a rare vagrant to Australia. In North America, it breeds along the southern edge of Hudson Bay and west of this body of water, and as far south as the Great Lakes west to Colorado, Nevada, and Oregon. The northern shoveler is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies. The conservation status of this bird is Least Concern. Taxonomy The northern shoveler was first formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his '' Systema Naturae''.

Betula Pendula
''Betula pendula'', commonly known as silver birch, warty birch, European white birch, or East Asian white birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe, it is only found at higher altitudes. Its range extends into Siberia, China, and southwest Asia in the mountains of northern Turkey, the Caucasus, and northern Iran. It has been introduced into North America, where it is known as the European white birch or weeping birch and is considered invasive in some states in the United States and parts of Canada. The tree can also be found in more temperate regions of Australia. The silver birch is a medium-sized deciduous tree that owes its common name to the white peeling bark on the trunk. The twigs are slender and often pendulous and the leaves are roughly triangular with doubly serrate margins and turn yellow and brown in autumn before they fall. The flowers are catkins and the light, winged seeds get widely s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dactylorhiza Incarnata
''Dactylorhiza incarnata'', the early marsh-orchid, is a perennial, temperate-climate species of orchid generally found growing in wet meadows, and generally on base-rich soils, up to about 2100m asl. The species occurs widely in Europe and Asia from Portugal and Ireland east to Siberia and Xinjiang.Petrova, A.S., Vladimirov, V. & Stoyanov, Y. (2009). ''Dactylorhiza maculata'' subsp. ''transsilvanica'' (Orchidaceae): new for the Bulgarian flora. Phytologia Balcanica 15: 389-392. There are several subspecies and also hybrids, rendering the identification of this species more difficult, but typically, the flowering spike is robust with a hollow stem, 25–60 cm tall, and bearing up to 50 flowers. Plants grow to a height of from 15 to 70 cm. The 4–7 erect yellowish-green leaves are hooded at the tip. The inflorescence is 4–12 cm long, with up to 50 blooms. The labellum appears long and narrow, since its sides are strongly reflexed (folded back). The tip is shallow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Typha Angustifolia
''Typha angustifolia'' L. (also lesser bulrush, narrowleaf cattail or lesser reedmace) is a perennial herbaceous plant of genus ''Typha''. This cattail is an "obligate wetland" species that is commonly found in the northern hemisphere in brackish locations. Description The plant's leaves are flat, very narrow (¼"–½" wide), and 3'–6' tall when mature; 12–16 leaves arise from each vegetative shoot. At maturity, they have distinctive stalks that are about as tall as the leaves; the stalks are topped with brown, fluffy, sausage-shaped flowering heads. The plants have sturdy, rhizomatous roots that can extend 27" and are typically ¾"–1½" in diameter. Distribution It has been proposed that the species was introduced from Europe to North America. In North America, it is also thought to have been introduced from coastal to inland locations. The geographic range of ''Typha angustifolia'' overlaps with the very similar species '' Typha latifolia'' (broadleaf or common c ...

Schoenoplectus Tabernaemontani
''Schoenoplectus tabernaemontani'' ( syn. ''Scirpus validus'') is a species of flowering plant in the sedge family known by the common names softstem bulrush, grey club-rush, and great bulrush. It can be found throughout much of the world; it has been reported from every state in the United States (including Hawaii), and from every province and territory in Canada except Nunavut. It grows in moist and wet habitat, and sometimes in shallow water. ''Schoenoplectus tabernaemontani'' is quite variable in appearance, thus explaining the long list of synonyms that have been created over the years. It is a perennial herb producing dense stands of many narrow erect stems reaching 1–3 m (33–100 inches) in height. It grows from a long rhizome system. The leaves are mostly basal and have wide sheaths around the stems. The inflorescence is generally a panicle of spikelets on long, thin branches which spread, arch, or droop. The spikelets vary in color. There is usually a long, stiff brac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alopecurus Aequalis
''Alopecurus aequalis'' is a common species of grass known as shortawn foxtail or orange foxtail. It is native to much of the temperate Northern Hemisphere from Eurasia to North America. It is most commonly found in areas near fresh water, such as the margins of ponds and ditches. Description This perennial bunchgrass is variable in appearance. It produces bunches of erect stems between 20 and about 70 centimeters in height. The leaves are 2-15 cm long; the basal leaves are the longest and the few stem leaves are long-sheathing. The cylindrical inflorescence is a few centimeters long and blooms with white to yellow to bright orange anthers about 0.5-0.8 mm long. The leaf blades are narrow, about 1-8 mm wide. The flowers are attached to branches, rather than the main axis of the inflorescence. Ecology ''A. aequalis'' has a C3 metabolism, grows best in full to partial sun, and can tolerate shallow standing water for up to two months during the growing season. One variety of thi ...

Nymphaea Alba
''Nymphaea alba'', the white waterlily, European white water lily or white nenuphar , is an aquatic flowering plant in the family Nymphaeaceae. It is native to North Africa, temperate Asia, Europe and tropical Asia (Jammu and Kashmir). Description It grows in water that is deep and likes large ponds and lakes. The leaves can be up to in diameter and take up a spread of per plant. The flowers are white and they have many small stamens inside. Taxonomy It was first published and described by Carl Linnaeus in his book ' Species Plantarum', on page 510 in 1753. The red variety (''Nymphaea alba'' f. ''rosea'') is cultivated from lake Fagertärn ("Fair tarn") in the forest of Tiveden, Sweden, where it was discovered in the early 19th century. The discovery led to large-scale exploitation which nearly made it extinct in the wild before it was protected. ''Nymphaea candida'' is sometimes considered a subspecies of ''N. alba'' (''N. alba'' L. subsp. ''candida'' ). Distributio ...
