 The Application of Remote Sensing to the Inventory of White Pine (Pinus Strobus L.) in Eastern Ohio, Research ...
This first application in Ohio of remote sensing and GIS technology to inventory a forest species for forest management and utilization purposes was successful, providing useful information and forming the foundation for further refinements of the technology.
This initial classification of land area into conifer or non-conifer saved much time compared to working with aerial photographs and performing the field work that would have been required with more traditional inventory methods.
Karteris (1990) used a six-band combination of Landsat TM data to achieve classification accuracies for individual stands of conifers ranging from 79.7 percent for Scotch pine (Pinus sylvestris L.) to 88.7 percent for Jack pine (Pinus banksiana Lamb.).

  Library of Congress Classification Encyclopedia   (Site not responding. Last check: )
The classification was originally developed by Herbert Putnam with the advice of Charles Ammi Cutter in 1897 before he assumed the librarianship of Congress.
It was influenced by Cutter Expansive Classification, DDC, and was designed for the use by the Library of Congress.
It has been criticized as lacking a sound theoretical basis; many of the classification decisions were driven by the particular practical needs of that library, rather than considerations of epistemological elegance.

 Standardized National Vegetation Classification System: A Standard National Vegetation Classification System
Although the classification units are defined by vegetation only, the concept of a community as an ecological unit includes all the biological and physical diversity associated with that specific vegetation type.
Problematic classifications and high-priority elements are targeted as a focus for future data acquisition and quantitative analyses to refine the classification of these types.
Classification is based on qualitative assessment of published field data or field data that are of questionable quality, that include limited numbers of samples, or have not been quantitatively analyzed.

Pinus is the botanical name for the Pine tree.
The leaves of seedling trees and up to a year or two are soft and produced singly surrounding the shoot.
The sheath varies in length, and in some kinds may fall soon after the leaves form, or may remain until the leaves fall, which may be from 2 to 5 years.

 Pinus classification - Biocrawler
There are three main subgenera of Pinus, the subgenus Strobus (White pines or soft pines), the subgenus Ducampopinus (Pinyon, Bristlecone and Lacebark pines), and the subgenus Pinus (Typical pines, or yellow or hard pines).
This classification into the three subgenera is based on cone, seed and leaf characters:
In general, cone and cone scale and seed morphology and leaf fascicle and sheath morphology are emphasized and this seems to result in a classification that has subsections of pines that are understandable and usually readily recognized by their general appearance.

 Pinus description
The portion of the cone scale that is exposed before the mature cone opens is thickened and is called the umbo; it may be unarmed, or armed with a spine or prickle; and it may be formed into a woody pyramid called an apophysis.
The number of leaves per fascicle, the length of needles, the number of sides of the needles (only Pinus monophylla has a round needle), the distribution of stomata (waxy white specks on the leaf surface), and the color and stiffness of the needles can all be useful characters for identification.
In many areas Pinus is a forest dominant, either early successional or longer-lived, persisting in the late successional forest.

These susceptibility classifications are defined in table 6.1, and were devised by Hawksworth and Wiens (1972).
The susceptibility classification (table 6.1) is not a measure of the frequency with which a host species may be infested over its geographical distribution.
Host susceptibility classification is usually based on direct field observations; for those cases where data are lacking, we classified taxa on the basis of our field experience.

 Pine   (Site not responding. Last check: )
[[Loblolly Pine (''Pinus taeda''): male cones]] Pines are mostly monoecious, having the male and female cones on the same tree, though a few species are sub-dioecious with individuals predominantly, but not wholly, single-sex.
The male Cones are small, typically 1-5 cm long, and only present for a short period (usually in spring, though autumn in a few pines), falling as soon as they have shed their pollen.

Classification Comments: (Pinus taeda) - Quercus falcata / Gaylussacia frondosa Forest (CEGL006169) has been archived and incorporated into this type by Gary Fleming.
The overstory of mid- to late-successional stands is dominated by a mixture of oaks, such as Quercus alba, Quercus falcata, and Quercus velutina.
The relative cover of Pinus taeda is likely related to disturbance history, with higher pine cover suggesting more recent disturbance.

The most common Pinus species found on campus is the Aleppo pine (Pinus halapensis), followed by the Mondel or Afgan pine (Pinus eldarica).
It is only after they reach full maturity that the shape of the halapensis changes, creating many different structural canopy shapes, and classification becomes easier.
Pinus eldarica maintains a Christmas tree structure after maturity, as seen in the photo above.

The binomial (‘two stage naming’) system gives a precise classification of the particular plant, and these classifications are to be found Linnaeus’s two definitive original works: Genera plantarum and Species plantarum.
The botanist’s name is important because for example, the Arolla pine tree was classifed as Pinus montana Lamark (syn.
Pinus cembra L.) whereas Pinus montana (Miller) is now taken as syn Pinus mugo Turra – the Mountain Pine.

Finnish forests are also categorised according to the forest type classification developed by A.K. Cajander.
The system is based on the fact that the competition between species and their different requirements lead to the development of a unified vegetation or forest type in each type of habitat.
Scots pine (Pinus sylvestris) is the dominant tree species in 65 percent of tree stands.
