Pinus Elliottii
''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] |
George Engelmann
George Engelmann, also known as Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-American botanist. He was instrumental in describing the flora of the west of North America, then very poorly known to Europeans; he was particularly active in the Rocky Mountains and northern Mexico, one of his constant companions being another German-American, the botanical illustrator Paulus Roetter. Biography Origins George Engelmann was born in Frankfurt am Main, Germany, the oldest of thirteen children, nine of whom reached maturity. His father, Julius Bernhardt Engelmann, was a member of a family from which for several successive generations were chosen ministers for the Reformed Church at Bacharach-on-the-Rhine. Julius was a graduate of the University of Halle, and was also educated for the ministry, but he devoted his life to education. He established a school for young women in Frankfurt, which was rare at the time. George Engelmann's mother, Julie Antoinette, was the ...

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] |
Rust (fungus)
Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales (previously known as Uredinales). An estimated 168 rust genera and approximately 7,000 species, more than half of which belong to the genus ''Puccinia'', are currently accepted. Rust fungi are highly specialized plant pathogens with several unique features. Taken as a group, rust fungi are diverse and affect many kinds of plants. However, each species has a very narrow range of hosts and cannot be transmitted to non-host plants. In addition, most rust fungi cannot be grown easily in pure culture. A single species of rust fungi may be able to infect two different plant hosts in different stages of its life cycle, and may produce up to five morphologically and cytologically distinct spore-producing structures viz., spermogonia, aecia, uredinia, telia, and basidia in successive stages of reproduction. Each spore type is very host specific, and can typically infect only one kind of plant. Rust fungi are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect And Disease Conditions In The United States, 1979-83 - What Else Is Growing In Our Forests%3F (1985) (19950795404)
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from egg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusiform Rust
Fusiform means having a spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel. Examples * Fusiform, a body shape common to many aquatic animals, characterized by being tapered at both the head and the tail * Fusiform, a classification of aneurysm * Fusiform bacteria (spindled rods, that is, fusiform bacilli), such as the Fusobacteriota * Fusiform cell (biology) * Fusiform face area, a part of the human visual system which seems to specialize in facial recognition * Fusiform gyrus, part of the temporal lobe of the brain * Fusiform muscle, where the fibres run parallel along the length of the muscle * Fusiform neuron, a spindle-shaped neuron A neuron, neurone, or nerve cell is an electrically excitable cell that communicates with other cells via specialized connections called synapses. The neuron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hickory
Hickory is a common name for trees composing the genus ''Carya'', which includes around 18 species. Five or six species are native to China, Indochina, and India (Assam), as many as twelve are native to the United States, four are found in Mexico, and two to four are native to Canada. A number of hickory species are used for products like edible nuts or wood. Hickories are temperate forest trees with pinnately compound leaves and large nuts. Hickory flowers are small, yellow-green catkins produced in spring. They are wind-pollinated and self-incompatible. The fruit is a globose or oval nut, long and diameter, enclosed in a four-valved husk, which splits open at maturity. The nut shell is thick and bony in most species, and thin in a few, notably the pecan (''C. illinoinensis''); it is divided into two halves, which split apart when the seed germinates. Etymology The name "hickory" derives from a Native American word in an Algonquian language (perhaps Powhatan). It is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smokey Bear
Smokey Bear is an American campaign and advertising icon of the U.S. Forest Service. In the Wildfire Prevention Campaign, which is the longest-running public service announcement campaign in United States history, the Ad Council, the United States Forest Service (USFS), and the National Association of State Foresters (NASF), in partnership with creative agency FCB, employ Smokey Bear to educate the public about the dangers of unplanned human-caused wildfires. A campaign began in 1944 featuring Smokey and the slogan "Smokey Says – Care Will Prevent 9 out of 10 Forest Fires". His slogan changed to "Remember... Only YOU Can Prevent Forest Fires" in 1947 and was associated with Smokey Bear for more than five decades. In April 2001, the message was officially updated to "Only You Can Prevent Wildfires" in response to a massive outbreak of wildfires in natural areas other than forests (such as grasslands), and to clarify that Smokey was promoting the prevention of unplanned outdoo ...

Controlled Burn
A controlled or prescribed burn, also known as hazard reduction burning, backfire, swailing, or a burn-off, is a fire set intentionally for purposes of forest management, farming, prairie restoration or greenhouse gas abatement. A controlled burn may also refer to the intentional burning of slash and fuels through burn piles. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Hazard reduction or controlled burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. Controlled burning stimulates the germination of some desirable forest trees, and reveals soil mineral layers which increases seedling vitality, thus renewing the forest. Some cones, such as those of lodgepole pine and sequoia, are pyriscent, as well as many chaparral shrubs, meaning they require heat from fire to open cones to disperse seeds. In industrialized countries, controlled burning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flatwoods
Flatwoods, pineywoods, pine savannas and longleaf pine-wiregrass ecosystem are terms that refer to an ecological community in the southeastern coastal plain of North America. Flatwoods are an ecosystem maintained by wildfire or prescribed fire and are dominated by longleaf pine (''Pinus palustris''), and slash pine (''Pinus elliotii'') in the tree canopy and saw palmetto (''Serenoa repens''), gallberry (''Ilex glabra'') and other flammable evergreen shrubs in the understory, along with a high diversity of herb species.Platt, W.J. 1999.

East Texas
East Texas is a broadly defined cultural, geographic, and ecological region in the eastern part of the U.S. state of Texas that comprises most of 41 counties. It is primarily divided into Northeast and Southeast Texas. Most of the region consists of the Piney Woods ecoregion. East Texas can sometimes be defined only as the Piney Woods. At the fringes, towards Central Texas, the forests expand outward toward sparser trees and eventually into open plains. According to the ''Handbook of Texas'', the East Texas area "may be separated from the rest of Texas roughly by a line extending from the Red River in north-central Lamar County southwestward to east-central Limestone County and then southeastward towards eastern Galveston Bay". Most sources separate the Gulf Coast area into a separate region. Another popular, somewhat simpler, definition defines East Texas as the region between the Trinity River, north and east of Houston (or sometimes Interstate 45, when defining generou ...
