Max Bog
Max Bog is a 10.6 hectare biological Site of Special Scientific Interest in North Somerset, notified in 1988. The site is owned by North Somerset Council and managed by the Avon Wildlife Trust for the range of wetland plants that it supports. There is no access without a permit. Ecology Marsh Helleborine occurs here and nowhere else in Avon. Lesser Butterfly-orchid and Fragrant Orchid also occur here, and at only one other Avon site each. It is also home to Yellow Rattle, Meadow Sweet and Meadow Thistle. The reserve is also important for its invertebrate interest and is home to many species of moth, grasshopper and dragonfly.

Meadow Sweet
''Filipendula ulmaria'', commonly known as meadowsweet or mead wort, is a perennial herbaceous plant in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia (Near east and Middle east). It has been introduced and naturalised in North America. Meadowsweet has also been referred to as queen of the meadow, pride of the meadow, meadow-wort, meadow queen, lady of the meadow, dollof, meadsweet, and bridewort. Description The stems, growing up to 120 cm, are tall, erect and furrowed, reddish to sometimes purple. The leaves are dark-green on the upper side and whitish and downy underneath, much divided, interruptedly pinnate, having a few large serrate leaflets and small intermediate ones. Terminal leaflets are large, 4–8 cm long, and three- to five-lobed. Meadowsweet has delicate, graceful, creamy-white flowers clustered close together in irregularly-branched cymes, having a very strong, sweet smell redolent of antisep ...

Bogs Of England
A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials often mosses, typically sphagnum moss. It is one of the four main types of wetlands. Other names for bogs include mire, mosses, quagmire, and muskeg; alkaline mires are called fens. A baygall is another type of bog found in the forest of the Gulf Coast states in the United States.Watson, Geraldine Ellis (2000) ''Big Thicket Plant Ecology: An Introduction'', Third Edition (Temple Big Thicket Series #5). University of North Texas Press. Denton, Texas. 152 pp. Texas Parks and Wildlife. Ecological Mapping systems of Texas: West Gulf Coastal Plain Seepage Swamp and Baygall'. Retrieved 7 July 2020 They are often covered in heath or heather shrubs rooted in the sphagnum moss and peat. The gradual accumulation of decayed plant material in a bog functions as a carbon sink. Bogs occur where the water at the ground surface is acidic and low in nutrients. In contrast to fens, they derive mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yanal Bog
Yanal Bog () is a 1.6 hectare biological Site of Special Scientific Interest on the southern edge of the North Somerset Levels, just north of the village of Sandford, North Somerset. It was notified as an SSSI in 1988. Site description Yanal Bog is a calcicolous lowland mire. Underlying the site are gravels and clay alluvium. Above this sits a layer of peat. This results in a high water table, creating a distinct domed landscape feature. Biological interest The plant communities of the mire are nationally rare in Britain, and support two species, Black Bog-rush (''Schoenus nigricans'') and Blunt-flowered Rush ('' Juncus subnodulosus''), that have restricted distributions in south-west England, and a number of species that are localised in the North Somerset area. Surrounding the raised mire is a belt of grassland; although this is included within the SSSI, it is largely made up of common grass and herb species. In the community in the western part of the mire, Blunt-flowe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dactylorhiza
''Dactylorhiza'' is a genus of flowering plants in the orchid family Orchidaceae. Its species are commonly called marsh orchids or spotted orchids. ''Dactylorhiza'' were previously classified under '' Orchis'', which has two round tubers. Description They are hardy tuberous geophytes. In a thickened underground stem, they can store a large amount of water to survive arid conditions. The tuber is flattened and finger-like. The long leaves are lanceolate and, in most species, also speckled. They grow along a rather long stem which reaches a height of . Leaves higher on the stem are shorter than leaves lower on the stem. The inflorescence, compared to the length of the plant, is rather short. It consists of a compact raceme with 25-50 flowers. These develop from axillary buds. The dominant colors are white and all shades of pink to red, sprinkled with darker speckles. Taxonomy Etymology The name ''Dactylorhiza'' is derived from Greek words δάκτυλος ''daktylos'' 'finger' an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow-leaved Marsh-orchid
''Dactylorhiza traunsteineri'', the narrow-leaved marsh orchid or Traunsteiner's dactylorhiza, is a terrestrial species of orchid native to the cooler parts of the Eastern Hemisphere. It is native to Scandinavia, the Alps, and a region extending from Germany to Western Siberia Western Siberia or West Siberia (russian: Западная Сибирь, Zapadnaya Sibir'; kk, Батыс Сібір) is a part of the larger region of Siberia that is mostly located in the Russian Federation. It lies between the Ural region an .... Although said by some sources to occur in Britain and Ireland, others say that plants identified as this species are actually ''Dactylorhiza majalis'' subsp. ''traunsteinerioides'',, p. 876 a view supported by genetic data. Five subspecies are recognized as of June 2014: #''Dactylorhiza traunsteineri'' subsp. ''curvifolia'' (F.Nyl.)

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or ...

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a Nymph (biology), nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and for ...

Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Cirsium Dissectum
''Cirsium dissectum'', also known as meadow thistle, is an erect perennial herb. It is found in England, Wales, Ireland, France, the Netherlands, Germany, Italy, Spain, Hungary, Norway, etc. It is found in fens and less acidic peat bogs i.e. it prefers damp boggy areas. Description ''Cirsium dissectum'' grows 15 to 50 cm tall. It resembles a more slender version of ''Cirsium heterophyllum'' in having a grooved cottony stem and lanceolate shaped leaves, that have prickles and not spines. However the leaves are narrower (under 3 cm), less hairy underneath, and hairy on top. The flower heads are 2 to 3 cm long, the florets being dark red/purple, flowering from June until August. The plant has runners. Similar species ''Cirsium tuberosum'' or tuberous thistle, has tuberous roots rather than runners, and the leaves are twice pinnated. It is found in Calcareous grasslands but very rare. It has been recorded in Britain in the counties of Cambridg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow Rattle
''Rhinanthus minor'', known as yellow rattle, is a herbaceous wildflower in the genus '' Rhinanthus'' in the family Orobanchaceae (the broomrapes). It has circumpolar distribution in Europe, Russia, western Asia, and northern North America. An annual plant, yellow rattle grows up to tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds. The preferred habitat of ''Rhinanthus minor'' is dry fields or meadows; it tolerates a wide range of soil types. It flowers in the summer between May and September. It is hemiparasitic, notably on Poaceae (grasses) and Fabaceae (legumes), and farmers consider it to be a pest, as it reduces grass growth. Yellow rattle is used to create or restore wildflower meadows, where it maintains species diversity by suppressing dominant grasses and the recycling of soil nutrients. The seed is sown thinly onto grassland from August to November—to germinate the following spring, the seeds need to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100- metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, ...
