Quercus Ilicifolia
''Quercus ilicifolia'', commonly known as bear oak or scrub oak, is a small shrubby oak native to the eastern United States and southeastern Canada. Its range extends in the United States from Maine to North Carolina, with reports of a few populations north of the international frontier in Ontario. The name ''ilicifolia'' means "holly-leaved." Description ''Quercus ilicifolia'' is a deciduous tree or shrub growing occasionally reaching a height of 6 meters (20 feet) but usually much smaller. It is "gangly" and can form a dense thicket. The plant grows from a large taproot which can be up to 20 centimeters (8 inches) thick. The taproot lives a long time, producing several generations of above-ground parts. The alternately arranged leaves are each up to 15 cm (6 in) long by 10 cm (4 in) wide. The species is monoecious, with plants bearing both male catkins and solitary or clustered female flowers. The egg-shaped acorn is long with a saucer-shaped cap. The pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaylussacia Baccata
''Gaylussacia baccata'', the black huckleberry, is a common huckleberry found throughout a wide area of eastern North America. Distribution The plant is native to Eastern Canada and the Great Lakes region, the Midwestern and Northeastern United States, and the Appalachian Mountains, the Ohio/Mississippi/Tennessee Valley, and Southeastern United States. The range extends from Newfoundland west to Manitoba and Minnesota, south as far as Arkansas, Alabama, and Georgia. Description ''Gaylussacia baccata'' closely resembles the native blueberry plants (''Vaccinium'' species) with which it grows in the same habitats. However, it can be readily identified by the numerous resin dots on the undersides of the leaves which glitter when held up to the light. ''Gaylussacia baccata'' is a shrub up to 150 cm (5 feet) tall, forming extensive colonies. Flowers are in dangling groups of 3–7, orange or red, bell-shaped. Berries are dark blue, almost black, rarely white. Berries are sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shade Tolerance
In ecology, shade tolerance is a plant's ability to tolerate low light levels. The term is also used in horticulture and landscaping, although in this context its use is sometimes imprecise, especially in labeling of plants for sale in commercial nurseries. Shade tolerance is a complex, multi-faceted property of plants. Different plant species exhibit different adaptations to shade, and a particular plant can exhibit varying degrees of shade tolerance, or even of requirement for light, depending on its history or stage of development. Basic concepts Except for some parasitic plants, all land plants need sunlight to survive. However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss. Plants adapted to shade have the ability to use far-red light (about 730 nm) more effectivel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Browsing (herbivory)
Browsing is a type of herbivory in which a herbivore (or, more narrowly defined, a folivore) feeds on leaves, soft shoots, or fruits of high-growing, generally woody plants such as shrubs. This is contrasted with grazing, usually associated with animals feeding on grass or other lower vegetations. Alternatively, grazers are animals eating mainly grass, and browsers are animals eating mainly non-grasses, which include both woody and herbaceous dicots. In either case, an example of this dichotomy are goats (which are primarily browsers) and sheep (which are primarily grazers). Browse The plant material eaten is known as ''browse'' and is in nature taken directly from the plant, though owners of livestock such as goats and deer may cut twigs or branches for feeding to their stock. In temperate regions, owners take browse before leaf fall, then dry and store it as a winter feed supplement. In time of drought, herdsmen may cut branches from beyond the reach of their stock, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable fire in an area of combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire( in Australia), desert fire, grass fire, hill fire, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurrence of wildfires throughout the history of terrestrial life invites conjecture tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gneiss
Gneiss ( ) is a common and widely distributed type of metamorphic rock. It is formed by high-temperature and high-pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Gneiss forms at higher temperatures and pressures than schist. Gneiss nearly always shows a banded texture characterized by alternating darker and lighter colored bands and without a distinct cleavage. Gneisses are common in the ancient crust of continental shields. Some of the oldest rocks on Earth are gneisses, such as the Acasta Gneiss. Description Orthogneiss from the Czech Republic In traditional English and North American usage, a gneiss is a coarse-grained metamorphic rock showing compositional banding ( gneissic banding) but poorly developed schistosity and indistinct cleavage. In other words, it is a metamorphic rock composed of mineral grains easily seen with the unaided eye, which form obvious compositional layers, but which has only a weak tendency to fra ...

Long Island
Long Island is a densely populated island in the southeastern region of the U.S. state of New York, part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the 18th-most populous in the world. The island begins at New York Harbor approximately east of Manhattan Island and extends eastward about into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four counties: Kings and Queens counties (the New York City boroughs of Brooklyn and Queens, respectively) and Nassau County share the western third of the island, while Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens. Culturally, many people in the New York metropolitan area colloquially use the term "Long Island" (or "the Island") to refer exclusively to Nassau and Suffolk counties, and con ...

Long Island Central Pine Barrens
The Long Island Central Pine Barrens (also known as the Long Island Pine Barrens) is a large area of publicly protected pine barrens in Suffolk County, New York, on Long Island, covering more than . The Barrens operates in a similar manner to Adirondack Park, with public lands managed by a mix of federal, state, county and local public land managers intermixed with private inholdings. It is Long Island's largest natural area and its last remaining wilderness. The region contains a remnant of the Atlantic coastal pine barrens ecoregion, whose forests might once have covered a quarter million acres (1,000 km²) on Long Island. The Central Pine Barrens overlays and recharges a portion of a federally designated sole source aquifer for Long Island's drinking water. All of Long Island's drinking water comes from ground water wells; none of the island's water comes from reservoirs. Almost all of the Peconic River and Carmans River (two of Long Island's four biggest rivers) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pine Barrens (New Jersey)
The New Jersey Pine Barrens, also known as the Pinelands or simply the Pines, is the largest remaining example of the Atlantic coastal pine barrens ecosystem, stretching across more than seven counties of New Jersey. Two other large, contiguous examples of this ecosystem remain in the northeastern United States: the Long Island Central Pine Barrens and the Massachusetts Coastal Pine Barrens. The name pine barrens refers to the area's sandy, acidic, nutrient-poor soil. Although European settlers could not cultivate their familiar crops there, the unique ecology of the Pine Barrens supports a diverse spectrum of plant life, including orchids and carnivorous plants. The area is also notable for its populations of rare pygmy pitch pines and other plant species that depend on the frequent fires of the Pine Barrens to reproduce. The sand that composes much of the area's soil is referred to by the locals as sugar sand. The Pine Barrens remains mostly rural and undisturbed despite its ...

Pinus Rigida
''Pinus rigida'', the pitch pine, is a small-to-medium-sized pine. It is native to eastern North America, primarily from central Maine south to Georgia and as far west as Kentucky. It is found in environments which other species would find unsuitable for growth, such as acidic, sandy, and low-nutrient soils. Description The pitch pine is irregular in shape, but grows to ). Branches are usually twisted, and it does a poor job at self-pruning. The needles are in fascicles (bundles) of three, about in length, and are stout (over broad) and often slightly twisted. The cones are long and oval, with prickles on the scales. Trunks are usually straight with a slight curve, covered in large, thick, irregular plates of bark. Pitch pine has an exceptionally high regenerative ability; if the main trunk is cut or damaged by fire, it can re-sprout using epicormic shoots. This is one of its many adaptations to fire, which also include a thick bark to protect the sensitive cambium layer from ...
