The Flora of Lithuania is estimated to comprise about 10,600 species. About 1,350 of these are vascular plants; about 335 are bryophytes; and about 2,000 are algae. Lichens are represented by about 500 species, and fungi by about 6,400 species. About 550 of these species are considered extinct or threatened. Protected areas now cover more than 12% of the territory of Lithuania.
Lithuania lies both in the boreal and the broadleaved (angiosperm) forest belts. A variety of species are therefore found within its relatively small territory, including species characteristic of the southern taiga. The occurrence of the hornbeam species Carpinus betulus marks the border between the predominantly broadleaved zone in the south and the coniferous zone in the north.
Forest cover in Lithuania has waxed and waned along with its fortunes; as a general rule, times of prosperity led to deforestation for agricultural uses. This tendency was seen during the Soviet occupation; forest cover was about 20% in 1948, and increased to about 30% by 1990, when Lithuania regained its independence. It has since been relatively stable. The general consensus of scientific opinion is that the optimum forest cover for Lithuania is about 33%.
Conifers constitute about 60% of the total forest area. They are concentrated in the northern, western, and eastern, and far southern sections of the country. The principal conifers are Scots Pine at about 40%, and Norway Spruce at about 20%.
Broadleaf trees dominate in the central areas of the country. Birches constitute about 18% of the total, followed by Black Alder (about 8%) and European Aspen (about 8%); oak, ash, and elm make up the remainder.
Old growth forests are relatively rare in Lithuania, numbering about 100. Data collected in 1998 suggested that these forests occupied about 580 km2.
About 5% of Lithuania is covered by wetlands; a number of these are classified as peat bogs, with about 6,700 distinct areas. Characteristic species of the peat bogs include Scheuchzeria palustris , Eriophorum (cotton-grass), sundew, cloudberry, cranberry species, and Andromeda polifolia (bog-rosemary).
The peat bogs are sometimes subject to forest fires in the summer; about 280 such fires were noted between 1994 and 1999.
Riparian and lacustrine (aquatic) flora present in Lithuania include duckweed, horsetails, bullrushes, sedges, and grasses.
The principal crop plants in Lithuania are rye, wheat, oats, barley, peas, potatoes, sugar beet, and flax. About 46% of the country is covered by cropland.
In addition to these major crops, various mushroom species are harvested; several species of berries are harvested, sometimes from the wild; and Common Hawthorn, Thyme, and Hypericum are important medicinal species.
Crop weeds in Lithuania include Hordeum vulgare (spring barley), Capsella bursa-pastoris, Chenopodium album, Papaver rhoeas, Sinapis arvensis, Spergula arvensis , and Viola arvensis . Galinsoga parviflora is one of the most troubling invasive species.
Latvia lies on the eastern shores of the Baltic Sea on the level northwestern part of the rising East European platform, between Estonia and Lithuania. About 98% of the country lies under 200 m (656 ft) elevation. With the exception of the coastal plains, the ice age divided Latvia into three main regions: the morainic Western and Eastern uplands and the Middle lowlands. Latvia holds over 12,000 rivers, only 17 of which are longer than 100 km (60 mi), and over 3,000 small lakes, most of which are eutrophic. The major rivers include the Daugava, the Lielupe, the Gauja, the Venta and the Salaca. Woodlands cover around 52% of the country. Other than peat, dolomite, and limestone, natural resources are scarce. Latvia has 504 km (313 mi) of sandy coastline, and the ports of Liepāja and Ventspils provide important warm-water harbors for the Baltic coast.
Peat is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. Sphagnum moss, also called peat moss, is one of the most common components in peat, although many other plants can contribute. The biological features of sphagnum mosses act to create a habitat aiding peat formation, a phenomenon termed 'habitat manipulation'. Soils consisting primarily of peat are known as histosols. Peat forms in wetland conditions, where flooding or stagnant water obstructs the flow of oxygen from the atmosphere, slowing the rate of decomposition. Peat properties such as organic matter content and saturated hydraulic conductivity can exhibit high spatial heterogeneity.
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. 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.
Sphagnum is a genus of approximately 380 accepted species of mosses, commonly known as sphagnum moss, also bog moss and quacker moss. Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 to 26 times as much water as their dry weight, depending on the species. The empty cells help retain water in drier conditions.
Cranberry Glades — also known simply as The Glades — are a cluster of five small, boreal-type bogs in southwestern Pocahontas County, West Virginia, United States. This area, high in the Allegheny Mountains at about 3,400 feet (1,000 m), is protected as the Cranberry Glades Botanical Area, part of the Monongahela National Forest. This site is the headwaters of the Cranberry River, a popular trout stream, and is adjacent to the nearly 50,000-acre (200 km2) Cranberry Wilderness.
Convolvulus arvensis, or field bindweed, is a species of bindweed in the Convolvulaceae native to Europe and Asia. It is a rhizomatous and climbing or creeping herbaceous perennial plant with stems growing to 0.5–2 metres (1.6–6.6 ft) in length. It is usually found at ground level with small white and pink flowers.
Scotstown Moor is in the north of Aberdeen, Scotland.
Agriculture in Lithuania dates to the Neolithic period, about 3,000 to 1,000 BC. It has been one of Lithuania's most important occupations for many centuries.
Meesia triquetra, the three-ranked hump-moss, is a moss that occurs all around the northern hemisphere in higher latitudes.
Forest farming is the cultivation of high-value specialty crops under a forest canopy that is intentionally modified or maintained to provide shade levels and habitat that favor growth and enhance production levels. Forest farming encompasses a range of cultivated systems from introducing plants into the understory of a timber stand to modifying forest stands to enhance the marketability and sustainable production of existing plants.
Cors Caron is a raised bog in Ceredigion, Wales. Cors is the Welsh word for "bog". Cors Caron covers an area of approximately 349 hectares. Cors Caron represents the most intact surviving example of a raised bog landscape in the United Kingdom. About 44 different species groups inhabit the area including various land and aquatic plants, fish, insects, crustaceans, lichen, fungi, terrestrial mammals and birds.
The flora of Australia comprises a vast assemblage of plant species estimated to over 21,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (Banksia), Myrtaceae, and Fabaceae.
Raised bogs, also called ombrotrophic bogs, are acidic, wet habitats that are poor in mineral salts and are home to flora and fauna that can cope with such extreme conditions. Raised bogs, unlike fens, are exclusively fed by precipitation (ombrotrophy) and from mineral salts introduced from the air. They thus represent a special type of bog, hydrologically, ecologically and in terms of their development history, in which the growth of peat mosses over centuries or millennia plays a decisive role. They also differ in character from blanket bogs which are much thinner and occur in wetter, cloudier climatic zones.
The native flora of Saskatchewan includes vascular plants, plus additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses. Non-native species of plants are recorded as established outside of cultivation in Saskatchewan, of these some non-native species remain beneficial for gardening, and agriculture, where others have become invasive, noxious weeds. Saskatchewan is committed to protecting species at risk in Canada. The growing season has been studied and classified into plant hardiness zones depending on length of growing season and climatic conditions. Biogeographic factors have also been divided into vegetative zones, floristic kingdoms, hardiness zones and ecoregions across Saskatchewan, and natural vegetation varies depending on elevation, moisture, soil type landforms, and weather. The study of ethnobotany uncovers the interrelation between humans and plants and the various ways people have used plants for economic reasons, food, medicine and technological developments. The Government of Saskatchewan has declared 3 indigenous plants as provincial symbols.
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes. More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creating a wide variety of different flora spanning over not just China, but different parts of the world.
Ireland is in the Atlantic European Province of the Circumboreal Region, a floristic region within the Holarctic.
Setaria palmifolia is a species of grass known by the common names palmgrass, highland pitpit, hailans pitpit, short pitpit, broadleaved bristlegrass, and knotroot. In Spanish it is called pasto de palma and in Samoan vao 'ofe 'ofe. It is native to temperate and tropical Asia. It is known elsewhere as an introduced, and often invasive, species, including in Australia, New Zealand, many Pacific Islands, and the Americas.
Paludiculture is wet agriculture and forestry on peatlands. Paludiculture combines the reduction of greenhouse gas emissions from drained peatlands through rewetting with continued land use and biomass production under wet conditions. “Paludi” comes from the Latin “palus” meaning “swamp, morass” and "paludiculture" as a concept was developed at Greifswald University. Paludiculture is a sustainable alternative to drainage-based agriculture, intended to maintain carbon storage in peatlands. This differentiates paludiculture from agriculture like rice paddies, which involve draining, and therefore degrading wetlands.
Wales has a surface area of 20,779 km2 or 2,077,900 ha. It has a border with England to the east, and is bounded by the Irish Sea to the north and west, and by the Bristol Channel to the south. It has an oceanic temperate climate which is markedly influenced by the North Atlantic Current carrying warm water from tropical latitudes. As a result, it has a much milder climate than most places in the world at similar latitudes. Altitudes range from sea-level to 1085 m on the Snowdon Massif.
Krustkalni Nature Reserve is a nature reserve located in eastern Latvia that was founded in 1977. It has an area of 2,978 hectares. Since 2004, this institution has been part of Natura 2000, a European Union network of protected areas. The reserve is managed by the Latgale regional administration.
