Helsby is a village, civil parish and electoral ward in Cheshire, England, which in 2011 had a population of 4,972.
Hapsford Hall is a country house located about 1 mi to the south of Helsby, Cheshire, England.
 It was built in the late 18th or early 19th century.
 The house incorporates a former farmhouse; additions and alterations have been made since it was built.
 It is constructed in brick and stone, stands on a stone plinth, has stone quoins, and a hipped slate roof.
 The house is in three storeys, with cellars and an attic, and has a symmetrical front of three bays.
 Most of the windows on the front are sashes, elsewhere are casement windows.
 An embattled stone porch projects from the centre.
 The house is recorded in the National Heritage List for England as a designated Grade II listed building.
Woodham Walter Common SSSI is an 80 hectare biological Site of Special Scientific Interest (SSSI) in Danbury in Essex.
 The site includes six nature reserves within the Danbury Ridge Nature Reserves, managed by the Essex Wildlife Trust.
 These are Woodham Walter Common itself, Birch Wood, Pheasanthouse Wood, Poors' Piece, Scrubs Wood and a small area in Pheasanthouse Farm.
 The largest part of the SSSI is the 32.3 hectare Woodham Walter Common, which is managed by the Wildlife Trust on behalf of Maldon District Council and Woodham Walter Parish Council.
Swithland Wood is a public woodland in Charnwood Forest, in Leicestershire.
 Although close to the village of Swithland, it is almost entirely within the parish of Newtown Linford.
 It is just north of Bradgate Park and also near Woodhouse Eaves and Cropston.
 The wood is part of the "Swithland Wood and The Brand" SSSI, noted for both its biological and geological interest, and is Leicestershire's most important ancient woodland for nature conservation.
 Quarries within the wood were a source of the distinctive "Swithland Slate" roofs found on many local buildings as well as the slate gravestones common in Leicestershire churchyards.
 Swithland Wood has been a public woodland since 1925, upon its acquisition by the Leicester Rotary Club, having previously been part of the estate of the manor of Groby.
 Since 1931 it has been managed by the Bradgate Park and Swithland Wood Trust.
Zootermopsis angusticollis is a species of termite (Isoptera) in the family Termopsidae, a group known as the dampwood termites.
 As their name suggests, the dampwood termites can only survive by living off of wood that contains high amounts of moisture.
 Unlike the more common drywood termites, the dampwood termites are very tolerant of wet conditions and build their colonies in damp wood such as rotting stumps and logs.
 They have even been found in areas of tidal flooding.
 They are common in wet coastal areas like the Pacific coast of North America.
 Most are found in the states of California, Oregon, Washington, Montana and in southern British Columbia.
 Termites are well known to be destroyers of wood, and although the dampwood termites can cause some damage, they are not as notoriously known to cause as much damage to buildings as the drywood termites.
 They tend to stick to dense forest areas with heavy amounts of decaying wood.
 A dampwood colony can easily be found by peeling the bark away from rotten stumps.
 The dampwood termites are also known for possessing intestinal flagellate protozoa, of the genus "Trichonympha", with which they have a symbiotic relationship.
Far from the most common energy supply, the sun, and from many nutrient supplies closely tied to the surface, the deep sea is still home to a unique ecosystem.
 Deep-sea wood is the term for wood which sinks to the ocean floor.
 All organisms of the ocean floor face unique challenges in synthesizing ATP/GTP needed for cellular function and replication.
 In this case, deep-sea wood supports a unique form of deep sea community life including chemo-synthetic bacteria.
 Sources of carbon for these organisms are not limited to wood, but also include kelp and the remains of whales.
 As it is difficult and very costly to simply discover logs that have fallen to the ocean floor, much of what is known about deep-sea wood is obtained from experiments by marine biologists, in which wood is forced to the bottom of the ocean for a set amount of time and is then collected later for sampling.
Oxalis acetosella (wood sorrel or common wood sorrel) is a rhizomatous flowering plant in the family "Oxalidaceae", common in most of Europe and parts of Asia.
 The specific name is acetosella, refers to its sour taste.
 The common name wood sorrel is often used for other plants in the genus "Oxalis".
 In much of its range it is the only member of its genus and hence simply known as "the" wood sorrel.
 While common wood sorrel may be used to differentiate it from most other species of "Oxalis", in North America, "Oxalis montana" is also called common wood sorrel.
 It is also known as "Alleluia" because it blossoms between Easter and Pentecost, when the Psalms which end with Hallelujah are sung.
Danbury Ridge Nature Reserves are a group of nature reserves totalling 101 hectares near Danbury in Essex.
 They are managed by the Essex Wildlife Trust, and most of them are in Sites of Special Scientific Interest (SSSIs).
 Two areas, the Backwarden and Hitchcock's Meadow, are part of Danbury Common SSSI, and Woodham Walter Common, Birch Wood, Pheasanthouse Wood, Poors Piece, Scrubs Wood, and a small area in Pheasanthouse Farm, are part of Woodham Walter Common SSSI.
Harmers wood is a small woodland with sandstone quarries in Helsby village in the north of Cheshire, England.
 It is a nine-acre woodland containing mainly silver birch trees with some oak and a smattering of holly trees, rowan, hawthorn and gorse.
 The wood is owned by the Friends of Harmers Wood Trust Ltd as a not-for-profit business managed on behalf of the local community.
Farthings Wood is an ancient replanted woodland near Little Missenden in the English county of Buckinghamshire.
 The predominant tree species in the wood is Corsican pine, interspersed with beech, wild cherry, rowan, ash, silver birch, downy birch and sycamore.
 There are also Scots pine trees in the southern section of the wood, and hornbeam, oak and hawthorn around the boundaries of the wood.
 The shrub layer consists of a number of different species.
 The wood is home to two species of bats, namely the Common Pipistrelle and the Soprano Pipistrelle.
 The wood is threatened by the proposed route of the HS2 high-speed railway.
