Neyraudia Reynaudiana
''Neyraudia reynaudiana'', commonly known as Burma reed, silk reed, cane grass, or false reed, is a tall, perennial, large-plumed grass native to subtropical Asia, but invasive in southern Florida in the United States. Description The stems of Burma reed, with flower stalks, are from tall, depending on soil and moisture conditions. The leaves are long and hairless, except for a single line of horizontal hairs at the juncture of the upper and lower portions of the leaf. Stems are approximately wide, round, solid, and have nodes (stem-leaf junctures) every along the stem. The flower plumes, which can be up to long, are composed of many hundreds of tiny flowers and have a shimmery, silky appearance. Flowering occurs in April and October in south Florida, each clump producing an average of forty stalks and twelve to twenty flowering plumes. Burma reed resembles several other tall grasses, including common reed ('' Phragmites communis''), giant reed (''Arundo donax''), pampas gra ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

South Florida Rocklands
The South Florida rocklands ecoregion, in the tropical and subtropical moist broadleaf forests biome, occurs in southern Florida and the Florida Keys in the United States, where they would naturally cover an area of . These forests form on limestone outcrops with very thin soil; the higher elevation separating them from other habitats such as coastal marshes and marl prairies. On mainland Florida, rocklands exist primarily on the Miami Rock Ridge, which extends from the Miami River south to Everglades National Park. South Florida rocklands are further divided into pine rocklands and rockland hammocks. Pine rockland Description The pine rocklands are a critically imperiled ecosystem located in southern Florida, the Bahamas, Turks and Caicos Islands, and Cuba. Its location in south Florida and throughout the Caribbean Archipelago straddles the southern and northern ends of the temperate and tropical flora ranges, respectively. This helps explain why the pine rocklands ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grasses Of Asia
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Chloridoideae
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon'') or goosegrass (''Eleusine indica''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff (''Eragrostis tef''). With the exception of some species in ''Ellisochloa'' and Eleusine indica, most of the subfamily's species use the C4 photosynthetic pathway. The first evolutionary transition from C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene. Phylogeny Relationships of tribes in the Chloridoideae according to a 2017 phylogenetic classification, also showing the Danthonioideae as sister group: The following genera have not been assigned t ...

String Trimmer
A string trimmer, also known by the portmanteau strimmer and the trademarks Weedwacker, Weed eater and Whipper Snipper. is a garden tool for cutting grass, small weeds, and groundcover. It uses a whirling monofilament line instead of a blade, which protrudes from a rotating spindle at the end of a long shaft topped by a gasoline engine or electric motor. String trimmers are commonly used for cutting low foliage near obstacles or on steep or irregular terrain. Most professional-grade line trimmers can accept attachment blades to be used as brush cutters for more dense vegetation. History The first brush cutter was produced in Japan in 1960 by Echo tools, Echo. The U.S. string trimmer was invented in the early-1970s by George Ballas of Houston, Texas, who conceived the idea while watching the revolving action of the cleaning brushes in an automatic car wash. His first trimmer was made by attaching pieces of heavy duty fishing line to a tin can bolted to an edger. Ballas devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Andrew
Hurricane Andrew was a very powerful and destructive Category 5 Atlantic hurricane that struck the Bahamas, Florida, and Louisiana in August 1992. It is the most destructive hurricane to ever hit Florida in terms of structures damaged or destroyed, and remained the costliest in financial terms until Hurricane Irma surpassed it 25 years later. Andrew was also the strongest landfalling hurricane in the United States in decades and the costliest hurricane to strike anywhere in the country, until it was surpassed by Katrina in 2005. In addition, Andrew is one of only four tropical cyclones to make landfall in the continental United States as a Category 5, alongside the 1935 Labor Day hurricane, 1969's Camille, and 2018's Michael. While the storm also caused major damage in the Bahamas and Louisiana, the greatest impact was felt in South Florida, where the storm made landfall as a Category 5 hurricane, with 1-minute sustained wind speeds as high as 165 mp ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants. Observation Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs susp ...

Slash Pine
''Pinus elliottii'', commonly known as slash pine,Family, P. P. (1990). Pinus elliottii Engelm. slash pine. ''Silvics of North America: Conifers'', (654), 338. is a conifer tree native to the Southeastern United States. Slash pine is named after the "slashes" – swampy ground overgrown with trees and bushes – that constitute its habitat. Other common names include swamp pine, yellow slash pine, and southern Florida pine. Slash pine has two different varieties: ''P. e.'' var. ''elliottii'' and ''P. e.'' var. ''densa''. Historically, slash pine has been an important economic timber for naval stores, turpentine, and resin. The wood of slash pine is known for its unusually high strength, especially for a pine. It exceeds many hardwoods and is even comparable to very dense woods such as ironwood. Description and taxonomy This tree is fast-growing, but not very long-lived by pine standards (to 200 years). It reaches heights of with a trunk diameter of . The leaves are needle-like ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Everglades National Park
Everglades National Park is an American national park that protects the southern twenty percent of the original Everglades in Florida. The park is the largest tropical wilderness in the United States and the largest wilderness of any kind east of the Mississippi River. An average of one million people visit the park each year. Everglades is the third-largest national park in the contiguous United States after Death Valley and Yellowstone. UNESCO declared the Everglades & Dry Tortugas Biosphere Reserve in 1976 and listed the park as a World Heritage Site in 1979, and the Ramsar Convention included the park on its list of Wetlands of International Importance in 1987. Everglades is one of only three locations in the world to appear on all three lists. Most national parks preserve unique geographic features; Everglades National Park was the first created to protect a fragile ecosystem. The Everglades are a network of wetlands and forests fed by a river flowing per day out of Lake O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phragmites Communis
''Phragmites australis'', known as the common reed, is a species of plant. It is a broadly distributed wetland grass that can grow up to tall. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent studies have characterized morphological distinctions between the int ...
