Stora Träsket Nature Reserve
Stora Träsket Nature Reserve () is a nature reserve in Botkyrka Municipality close to Stockholm, Sweden. The nature reserve protects an area of wildlife around the lake Stora Träsket. The lake, with a maximum depth of is naturally becoming smaller with time, supporting large areas of reeds and floating mats at its fringes. These areas are a habitat for, among other species, the orchid '' Hammarbya paludosa'' and several species of sundew. On land, the lake is surrounded by old-growth forest containing several species which are used to identify areas of high ecological value; these include ''Goodyera repens'', ''Chimaphila umbellata'' and ''Geastrum pectinatum'', among others.

Hammarbya Paludosa
''Hammarbya paludosa'' (or ''Malaxis paludosa'') is a small orchid commonly known as bog orchid, bog adder's-mouth or bog adder's-mouth orchid. It grows in bogs in temperate and subarctic regions of the Northern Hemisphere. Taxonomy It was originally named ''Ophrys paludosa'' by Carl Linnaeus. The name ''paludosa'' refers to the boggy ground where it grows. In 1891, Otto Kuntze moved it to a new genus of its own called ''Hammarbya'', named after Hammarby, Linnaeus's summer residence.Harrap, Anne & Simon Harrap (2009) Orchids of Britain & Ireland: A Field and Site Guide, 2nd ed., A & C Black, London. .

Geastrum Pectinatum
''Geastrum pectinatum'' is an inedible species of mushroom belonging to the earthstar family of fungi. Although young specimens are spherical, fruit body development involves the outer layer of tissue splitting open like a star into 7 to 10 pointed rays that eventually bend back to point downward, revealing a small – broad – spore sac. The spore sac is supported by a small radially wrinkled stalk. There is a distinct conical opening (peristome) at the top of the spore sac that is up to long. It is commonly known as the beaked earthstar or the beret earthstar, in reference to the shape of the spore sac and its prominent, protruding peristome. The mass of spores and surrounding cells within the sac, the gleba, is dark-brown, and becomes powdery in mature specimens. Spores are spherical, measuring 4 to 6 micrometers in diameter, with warts on their surfaces. Although uncommon, ''G. pectinatum'' has a cosmopolitan distribution, and has been collected in various locations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimaphila Umbellata
''Chimaphila umbellata'', the umbellate wintergreen, pipsissewa, or prince's pine, is a small perennial flowering plant found in dry woodlands, or sandy soils. It is native throughout the cool temperate Northern Hemisphere. Description This plant grows up to 35 cm (12 in) tall, with one simple stem bearing evergreen, shiny, toothed leaves in opposite pairs or whorls of 3-5 (and sometimes more) along the stem. Leaves have a slightly spiny serrulate margin starting close to the base, and range from 1 ½ to 2 ½ inches long (or longer) with a typically oblanceolate shape. Flowers range from white to pink, produced in a small umbel of 4–8 together. The filaments have a roundish expansion at the base, bearing hairs along the margin only. In comparison, the closely related '' C. menziesii'' bears hairs on the ''back'' of the filament's expansion as well. Ecology Although it has green leaves year-round, it receives a significant portion of its nutrition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodyera Repens
''Goodyera repens'', an orchid in the genus ''Goodyera'', is called by the common name creeping lady's-tresses in Anglophone Europe and dwarf rattlesnake plantain or lesser rattlesnake plantain in North America. It is a green underground creeper that sends out occasional skinny stems above the surface. During the summer, these stems bear flowers arranged in a spiral. These flowers twist themselves to face toward the sun. ''Goodyera repens'' is found in isolated spots in the forests and bogs of Europe. It is a rare plant, but it is the most common orchid in Scandinavia. The species is widespread across much of Europe, Asia and North America including Russia, China, Germany, Poland, the United Kingdom, Canada and the United States, though never very common in any of these places. ''Goodyera repens'' is a protected species throughout most of its range. It does not survive fire, and does not soon reenter an area after fire or logging. It is generally found only in forests at le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old-growth Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree heights and diameters, and diverse tree species and classes and sizes of woody debris., the world has of primary forest ...

Drosera
''Drosera'', which is commonly known as the sundews, is one of the largest genus, genera of carnivorous plants, with at least 194 species. 2 volumes. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilage, mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the soil in which the plants grow. Various species, which vary greatly in size and form, are native to every continent except Antarctica. Charles Darwin performed much of the early research into ''Drosera'', engaging in a long series of experiments with ''Drosera rotundifolia'' which were the first to confirm carnivory in plants. In an 1860 letter, Darwin wrote, “…at the present moment, I care more about ''Drosera'' than the origin of all the species in the world.” Taxonomy The botanical name from the Ancient Greek, Greek ''drosos'' "dew, dewdrops" refer to the glistening drops of mucilage at the tip of the gla ...

Orchid
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is in the tropics. Orchidaceae is one of the two largest families of flowering plants, the other being the Asteraceae. It contains about 28,000 currently accepted species in 702 genera. The Orchidaceae family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genus of the vanilla plant), the type genus '' Orchis'', and many commonly cultivated plants such as '' Phalaenopsis'' and '' Cattleya''.

Floating Mat
A floating mat () is a layer of mosses and other, especially stoloniferous, plants that grows out from the shore across the surface of a lake or pond. This type of habitat is protected and is designated in the European Habitats Directive as "LRT No. 7140 Transition and Floating Mat Bogs". Landscapes with floating mats are characterized as quagmires. Floating mats are not always capable of bearing weight. There is a risk of drowning when walking on them. Formation The formation of floating mats is a process of sedimentation in water bodies. In bog ponds, floating mats of peat moss form as water levels fall and nutrient (plant), nutrients accumulate. In eutrophic waters, the formation of floating mats is caused by underwater peat that floats to the surface and is colonised by plants. The vegetative mats are held together by their root systems. Phragmites, Reeds or juncus, rushes growing by the lakeshore can eventually cut these mats off, which results in a floating island. ...
