Stenders Quarry
Stenders Quarry () is a biological and geological Site of Special Scientific Interest in the Forest of Dean, Gloucestershire, England, notified in 1966 and renotified in 1990. The site is designated as an SSSI for its important geological features, although there is also a diversity of plants and animals recorded. The site is listed in the 'Forest of Dean Local Plan Review' as a Key Wildlife Site (KWS). Stenders Quarry is situated west of Mitcheldean and is on the south side of the Drybrook road. The site was known formerly as the Wilderness Cement Work Quarry. The Quarry, which was gradually extended during the second half of the nineteenth century, provided material for the cement works. Scully Grove Quarry SSSI which is situated to the north also provided material for the cement works.. The remains of an overhead tramway, which was built to carry the limestone across the road, can be seen on the eastern side of Stenders Quarry. Working stopped in 1918 and the Quarry ...

Biological And Geological Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Salix Atrocinerea
''Salix atrocinerea'', commonly called grey willow or large gray willow, is a species of willow. It is a bush or small tree up to tall. As a pioneer species of willow, it quickly colonizes poor soils. Distribution The grey willow distribution is mostly Atlantic from Western Europe and North Africa to some Mediterranean islands. Naturally growing in Britain, France, Belgium, Spain, Portugal, Morocco, Tunisia, it is very common in the Iberian Peninsula, and is also found in Corsica. Ecology The species hybridizes readily with other species of willow and many hybrids have been identified. It flowers from January until March or April, depending on location, with the spread of seeds ripening from April to March. The grey willow lives in freshly disturbed land, with preference for acidic soil, but this is a very hardy species and is even found on beaches near the sea and on islands. It grows in sandy or gravel shores of rivers, streams and ponds, meadows, valleys and hedgerows with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crataegus Monogyna
''Crataegus monogyna'', known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world. Names This species is one of several that have been referred to as '' Crataegus oxyacantha'', a name that has been rejected by the botanical community as too ambiguous. In 1793, Medikus published the name ''C. apiifolia'' for a European hawthorn now included in ''C. monogyna,'' but that name is illegitimate under the rules of botanical nomenclature. Other common names include may, mayblossom, maythorn, (as the plant generally flowers in May in the English-speaking parts of Europe) quickthorn, whitethorn, motherdie, and haw. Description The common hawthorn is a shrub or small tree up to about tall, with a dense crown. The bark is dull brown with vertical orange cracks. The younger stems bear s ...

Dogwood
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''( Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood '' Cornus ...

Polypody
''Polypodium'' is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The genus is widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek ''poly'' (πολύ) "many" + ''podion'' (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypodies or rockcap ferns, but for many species unique vernacular names exist. They are terrestrial or epiphytic ferns, with a creeping, densely hairy or scaly rhizome bearing fronds at intervals along its length. The species differ in size and general appearance and in the character of the fronds, which are evergreen, persisting for 1–2 years, pinnate or pinnatifid (rarely simple entire), and from 10–80 cm or more long. The sori or groups of spore-cases (sporangia) are borne on the back of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lady-fern
''Athyrium'' (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales. Its genus name is from Greek '' a-'' ('without') and Latinized Greek '' thyreos'' ('shield'), describing its inconspicuous indusium (sorus' covering). The common name "lady fern" refers in particular to the common lady fern, '' Athyrium filix-femina''.Entry "lady fern", ''New Oxford American Dictionary 3rd edition'' (2010) by Oxford University Press, Inc.

Hart's-tongue
''Asplenium scolopendrium'', commonly known as the hart's-tongue fern, is an evergreen fern in the genus '' Asplenium'' native to the Northern Hemisphere. Description The most striking and unusual feature of the fern is its simple, undivided fronds. The leaves' supposed resemblance to the tongue of a hart (an archaic term for a male red deer) gave rise to the common name "hart's-tongue fern". Taxonomy Linnaeus first gave the hart's-tongue fern the binomial ''Asplenium scolopendrium'' in his ''Species Plantarum'' of 1753. The Latin specific epithet ''scolopendrium'' is derived from the Greek ''skolopendra'', meaning a centipede or millipede; this is due to the sori pattern being reminiscent of a myriapod's legs. A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. scolopendrium'' belongs to the "''Phyllitis'' subclade" of the "''Phyllitis'' clade". Members of the ''Ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wall-rue
''Asplenium ruta-muraria'' is a species of fern commonly known as wall-rue (but which, as a fern, is not by any means closely related to common rue). It is a very small epipetric species, growing exclusively on limestone and other calcareous rocks. Its fronds are bluish-green and are heavily sub-divided, becoming up to 12 cm in length. Taxonomy Linnaeus first gave wall-rue the binomial ''Asplenium ruta-muraria'' in his ''Species Plantarum'' of 1753. A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. ruta-muraria'' belongs to the "''Pleurosorus'' subclade" of the "''Pleurosorus'' clade". The ''Pleurosorus'' clade has a worldwide distribution; members are generally small and occur on hillsides, often sheltering among rocks in exposed habitats. ''A. ruta-muraria'' is exceptional within the subclade for its lack of hairs on the leaf. The phylogeny suggests th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
