Lindl
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his ...

Flora Of British Columbia
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Astereae
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae. The Taxonomy (biology), taxonomy of the tribe Astereae has been dramatically changed after both morphologic and molecular evidence suggested that large genera such as ''Aster (genus), Aster'', as well as many others, needed to be separated into several genera or shifted to better reflect the plants' relationships. A paper by R. D. Noyes and L. H. Rieseberg showed that most of the genera within the tribe in North America actually belong to a single clade, meaning they have a common ancestor. This is referred to as the North American clade. Guy L. Nesom and Harold E. Robinson have been involved in the recent work and ...

Wildfire Suppression
Wildfire suppression is a range of firefighting tactics used to suppress wildfires. Firefighting efforts depend on many factors such as the available fuel, the local atmospheric conditions, the features of the terrain, and the size of the wildfire. Because of this wildfire suppression in wild land areas usually requires different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Working in conjunction with specially designed aerial firefighting aircraft, fire engines, tools, firefighting foams, fire retardants, and using various firefighting techniques, wildfire-trained crews work to suppress flames, construct fire lines, and extinguish flames and areas of heat in order to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland–urban interface, where populated areas border with wild land areas. In the United States and other countries, aggressive wildfire suppression a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aira Praecox
''Aira praecox'' is a species of grass known by several common names, including early hair-grass, yellow hairgrass and spike hairgrass. It is native to Europe, where it is found in dry, sandy places, on rocky outcrops, and in heath grassland. It also grows in North America as an introduced species, where it can be found on the east and west coasts in sandy or rocky areas, such as beaches and roadsides. This is a tuft-forming annual grass growing up to about 10 to 15 centimeters in maximum height. The thin, narrow leaves are located at the base of the stem, and are typically 0.3–2 millimeters wide. It bears small, tightly congested inflorescences of purple-tinted green bisexual spikelets. It is an annual, forming low and small but numerous tufts. It flowers from April to June. Certain moths and butterflies, including the Grayling butterfly and the Coast Dart moth, feed on it as larva A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorp ...

Cytisus Scoparius
''Cytisus scoparius'' ( syn. ''Sarothamnus scoparius''), the common broom or Scotch broom, is a deciduous leguminous shrub native to western and central Europe. In Great Britain and Ireland, the standard name is broom; this name is also used for other members of the Genisteae tribe, such as French broom or Spanish broom; and the term ''common broom'' is sometimes used for clarification. In other English-speaking countries, the most common name is "Scotch broom" (or Scots broom); however, it is known as English broom in Australia. Though this plant is native to Europe, it has spread to many other parts of the world. Scotch broom is now common in certain areas of North America and South America. This is because people started introducing Scotch broom to different areas of the world. After it was introduced in North America, Scotch broom was frequently planted in gardens. Later, it was used for erosion control along highway cuts and fills. There are other problems with Scotch b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viola Adunca
''Viola adunca'' is a species of violet known by the common names hookedspur violet, early blue violet, sand violet, and western dog violet. It is native to meadows and forests of western North America, Canada, and the northern contiguous United States. Description This is a hairy, compact plant growing from a small rhizome system. The leaves are spade- or heart-shaped, sometimes with broadly wavy margins. They are generally 0.5 to 4 centimeters long.

Eriophyllum Lanatum
''Eriophyllum lanatum'', with the common names common woolly sunflower, Oregon sunshine and golden yarrow, is a common, widespread, North American plant in the family Asteraceae.Sierra Nevada Wildflowers, Karen Wiese, 2nd Ed. 2013, p. 116 Description ''Eriophyllum lanatum'' is a perennial herb growing from in height, in well-branched clumps. Both the stems and leaves may be covered with a woolly gray hair, but some plants lack this. The leaves are long, linear on the upper stems, and slender and pinnately lobed on the lower stems. The hairs conserve water by reflecting heat and reducing air movement across the leaf's surface. The flowers are yellow and composite, looking much like true sunflowers, and sometimes grow to about wide. Both the (8–12) ray and disk flowers are yellow, with one flower head on each flowering stalk. The flower heads have 6–14 rays, which are darker towards the base, and several disk flowers. They bloom from May to August. The seeds have scales a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amelanchier Alnifolia
''Amelanchier alnifolia'', the saskatoon berry, Pacific serviceberry, western serviceberry, western shadbush, or western juneberry, is a shrub native to North America. It is a member of the rose family, and bears an edible berry-like fruit. Description It is a deciduous shrub or small tree that most often grows to , rarely to , in height. Its growth form spans from suckering and forming colonies to clumped. The leaves are oval to nearly circular, long and broad, on a leaf stem, with margins toothed mostly above the middle.

Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on ever ...
