Oak Forest
An oak forest is a plant community with a tree canopy dominated by oaks (''Quercus spp.''). In terms of canopy closure, oak forests contain the most closed canopy, compared to oak savannas and oak woodlands. Examples * Southern dry-mesic oak forests in Minnesota dominated by red oak (''Quercus rubra''), white oak ('' Q. alba''), and basswood (''Tilia americana'') * Foloi oak forest in Greece, dominated by ''Quercus frainetto''Mauri, A., Enescu, C.

Flora Of The Northeastern United States
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Temperate Broadleaf And Mixed Forests In The United States
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Oak Woodland
An oak woodland is a plant community with a tree canopy dominated by oaks (''Quercus spp.''). In terms of canopy closure, oak woodlands are intermediate between oak savanna, which is more open, and oak forest, which is more closed. Although the community is named for the dominance of oak trees, the understory vegetation is often diverse and includes many species of grasses, sedges, forbs, ferns, shrubs, and other plants. Examples * Upper Midwestern United States oak woodlands dominated by white oak (''Quercus alba''), burr oak ('' Q. macrocarpa''), and black oak ('' Q. velutina''), with subdominant canopy species red oak (''Q. rubra'') and shagbark hickory (''Carya ovata''), with a diverse understory. The community is fire-dependent, shaped by annual, low-intensity fires. * Cork oak (''Quercus suber'') woodlands in the Mediterranean region. * Blue oak woodland is found in the inner coast ranges and the Sierra Nevada foothills in California, surrounding the Central Valley.C.

Oak Savanna
An oak savanna is a type of savanna—or lightly forested grassland—where oaks (''Quercus ''spp.) are the dominant trees. The terms "oakery" or "woodlands" are also used commonly, though the former is more prevalent when referencing the Mediterranean area. These savannas were maintained historically through wildfires set by lightning, humans, grazing, low precipitation, and/or poor soil. Although there are pockets of oak savanna almost anywhere in North America where oaks are present, there are three major oak savanna areas: 1) California, British Columbia, Washington and Oregon in the west; 2) Southwestern United States and northern Mexico; and 3) the prairie/forest border of the Midwestern United States. There are also small areas of oak savannas in other parts of the world. (See also Eastern savannas of the United States for information on pine savannas of the U.S. South.) Midwestern oak savannas The oak savannas of the Midwestern United States form a transition zone betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oak–heath Forest
An oak–heath forest is a plant community association and type of forest ecology. It is a deciduous forest type of well-drained, acidic soils, characterized by oaks (''Quercus'') and plants of the heath family (Ericaceae). It is commonly found in the high elevations of the eastern United States. Such forest areas typically have a dense fibrous root layer at the surface of the soil, and in many areas predominate on south-facing or southwest-facing slopes. Many of the existing oak–heath forests once featured American chestnut as an important canopy species.''The Natural Communities of Virginia Classification of Ecological Community Groups'' (Version 2.3), Virginia Department of Conservation and Re ...

Oak–hickory Forest
Oak–hickory forest is a type of North American forest ecosystem, and an ecoregion of the Temperate broadleaf and mixed forests Biome. Geography It has a range extending from Rhode Island and southern New York, west to Iowa, and south to Northern Georgia. Smaller, isolated oak–hickory communities can also be found as far west as North Dakota, south in Florida and in northeast Texas, and north to southern Maine and Ontario. They can also be found in Pennsylvania west to Illinois. Dominated by nut-bearing oak and hickory species of trees, the oak–hickory forest has the largest range of any deciduous forest ecosystem in eastern and central North America. Natural history The current oak–hickory forest includes the former range of the oak–chestnut forest region, which encompassed the northeast portion of the current oak–hickory range. When the American chestnut population succumbed to invasive fungal blight in the early 20th century, those forests shifted to an oak and hicko ...

Foloi Oak Forest
The Folóï oak forest ( el, Δρυοδάσος Φολόης) is an oak forest in southwestern Greece. It is located in the municipal unit Foloi, Elis, in the western part of the Peloponnese peninsula. The Folóï oak forest is situated at an altitude of 688m, on the plateau of the Folóï mountain. It is an ecosystem unique in the Balkan peninsula and consists of a territory of , which is almost entirely covered by deciduous oaks that form a dense forest area. Mythology The Pholóē oak forest was known to Ancient Greeks, because of its proximity to many of their settlements in the Elis region. The mysterious beauty of the forest inspired them to believe that it was a habitat of centaurs and dryads. They gave the forest the name ''Pholóē'' ( el, Φολόη, modern Greek pronunciation: Folóï) and the chief of the Centaurs the name ''Phólos'' ( el, Φόλος). The dryads ( el, Δρυάδες) were "oak spirits" of the forest. Flora The broadleaf oak, ''Quercus frainetto'' (H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Community
A plant community is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types. The components of each plant community are influenced by soil type, topography, climate and human disturbance. In many cases there are several soil types present within a given plant community. This is because the soil type within an area is influenced by two factors, the rate at which water infiltrates or exits (via evapotranspiration) the soil, as well as the rate at which organic matter (any carbon-based compound within the environment, such as decaying plant matter) enters or decays from the soil. Plant communities are studied substantially by ecologists, due to providing information on the effects of dispersal, tolerance to environmental conditions, and response to disturbance of a variety of plant species, information valuable to the comprehension of various plant ...
