British NVC Community W17
NVC community W17 (''Quercus petraea - Betula pubescens - Dicranum majus'' woodland) is one of the woodland communities in the British National Vegetation Classification system. It is one of the six communities falling in the "mixed deciduous and oak/birch woodlands" group. This is a widely distributed community in northern and western Britain and represents mossy deciduous woodland of the uplands. There are four subcommunities. Community composition Two constant species are found in the tree canopy of this community: * Sessile oak (''Quercus petraea'') * Downy birch (''Betula pubescens'') Eight constant species are found in the field and ground layers of this community: * Wavy hair grass (''Deschampsia flexuosa'') * Greater fork-moss (''Dicranum majus'') * Glittering wood-moss (''Hylocomium splendens'') * Waved silk-moss (''Plagiothecium undulatum'') * Red-stemmed feather-moss (''Pleurozium schreberi'') * Bank haircap moss (''Polytrichum formosum'') * Little shaggy-moss (''Rhy ...

Quercus Petraea
''Quercus petraea'', commonly known as the sessile oak, Cornish oak, Irish Oak or durmast oak, is a species of oak tree native to most of Europe and into Anatolia and Iran. The sessile oak is the national tree of Ireland, and an unofficial emblem in Wales and Cornwall. Description The sessile oak is a large deciduous tree up to tall, in the white oak section of the genus (''Quercus'' sect. ''Quercus'') and similar to the pedunculate oak (''Q. robur''), with which it overlaps extensively in range. The leaves are long and broad, evenly lobed with five to six lobes on each side and a petiole. The male flowers are grouped into catkins, produced in the spring. The fruit is an acorn long and broad, which matures in about six months. Comparison with pedunculate oak Significant botanical differences from pedunculate oak (''Q. robur'') include the stalked leaves, and the stalkless (sessile) acorns from which one of its common names is derived. It occurs in upl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanic Climate
An oceanic climate, also known as a marine climate, is the humid temperate climate sub-type in Köppen classification ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool summers and mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 45 and 63 latitude, most notably in northwestern Europe, northwestern America, as well as New Zealand. Precipitation Locations with oceanic climates tend to feature frequent cloudy conditions with precipitation, low hanging clouds, and frequent fronts and storms. Thunderstorms are normally few, since strong daytime heating and hot and cold air masses meet infrequently in the region. In most areas with an oceanic climate, precipitation comes in the form of rain for the majority of the year. However, some areas with this climate see some snowfall annually during winter. M ...

Rhytidiadelphus Triquetrus
''Rhytidiadelphus triquetrus'', the big shaggy-moss or rough goose neck moss, is a species of moss in the family Hylocomiaceae. It is often the dominating moss species in moderately rich forest habitats in the boreal regions and the Pacific Northwest. Because of its fuzzy appearance and tail-like shape it is also called the 'electrified cat's tail moss'. Not to be confused with square goose-necked moss, ''Rhytidiadelphus squarrosus''. Ecology Terrestrial on humus In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Lati ...-rich substrates in montane forests. Occasionally grows on logs and trees in lowland rainforests or on sandy-gravelly soils near streams. Response to herbicide application In a study of the effect of the herbicide Asulam on moss growth, ''Rhytidiadelphus triquetrus'' was ...

Agrostis Capillaris
''Agrostis capillaris'', the common bent, colonial bent, or browntop, is a rhizomatous and stoloniferous perennial in the grass family (Poaceae). It is native to Eurasia and has been widely introduced in many parts of the world. Colonial bent grows in moist grasslands and open meadows, and can also be found in agricultural areas, roadsides, and invading disturbed areas. The name '' Agrostis'' comes from the Greek word meaning forage plant, ''agros'' meaning "a field". It is found growing in neutral to acidic soils. It has a very fine texture and like most bent grasses grows very dense. Although this species is used on golf courses, providing some of the best ball playing surfaces in the world, it also produces a spectacular visual appearance when maintained properly. It provides an excellent home lawn but is not tolerant of heavy use. Colonial bent is fairly easy to grow from seeds and fertilization of the lawn is not as intense. This grass also takes longer to establish t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthoxanthum Odoratum
''Anthoxanthum odoratum'', known as sweet vernal grass, is a short-lived perennial grass that is native to acidic grassland in Eurasia and northern Africa. It is grown as a lawn grass and a house plant, due to its sweet scent, and can also be found on unimproved pastures and meadows. The specific epithet ''odoratum'' is Latin for 'odorous'. Description ''Anthoxanthum odaoratum'' is a short-lived perennial grass that grows in tufts with stems up to tall. The leaves are short and broad, wide, and glabrous to loosely hairy. It flowers in late spring and early summer, i.e. quite early in the season, with flower spikes of long and crowded spikelets of , oblong shaped, which can be quite dark when young. The lower lemmas have projecting awns. The ligules are quite long, up to , blunt, with hairy fringes around the side. The scent is particularly strong when dried, and is due to coumarin, a glycoside, and benzoic acid – it smells like fresh hay with a hint of vanilla. The see ...

''Diplophyllum albicans'' is a species of liverwort The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts.

Isothecium Myosuroides
''Isothecium myosuroides'', commonly known as slender mouse-tail moss or tree moss, is a true moss that grows abundantly on both rocks and trees. It is native to Western and Eastern North America, as well as parts of Western Europe. It grows preferentially on angiosperms rather than on conifers Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extan ... because of the manner in which the former take in water creating an ideal moist habitat for the moss to grow on, and because many trees in the flowering plant families are less acidic than coniferous species of trees. ''Isothecium myosuroides'' also can grow on rocks. References Lembophyllaceae {{hypnales-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
