  CONIFER CONE FACTS AND INFORMATION   (Site not responding. Last check: 2007-09-08)
In most of the genera, the cones are woody and the seeds have two narrow wings (one along each side of the seed), but in three genera (''Platycladus, Microbiota'' and ''Juniperus''), the seeds are wingless, and in ''Juniperus'', the cones are fleshy and berry-like.
The cones and seeds of ''Sciadopitys'' (the only member of the family) are similar to those of some Cupressaceae, but larger, 6-11 cm long; the scales are imbricate and spirally arranged, and have 5-9 ovules on each scale.
A further charateristic arrangement of pines is that the male cones are located at the base of the branch, while the female at the tip (of the same or a different branchlet).

 Volume 7 - Opinions of Counsel SBEA No. 107
Conifer trees may be considered "woodland products" and land on which such trees are grown is thus eligible for an agricultural value assessment.
A conifer cone is not a young growing plant and research has failed to disclose any instance in which the term "nursery stock", as ordinarily used, has been defined to include a conifer cone.
Since land used to produce conifer cones is apt to be covered with relatively mature trees, it would not be inconsistent to construe the term "woodland products" to include conifer cones.

 Conifer Collection
Conifers, known botanically as gymnosperms, are a diverse group of plants with sizes, shapes, textures, and colors that go beyond the conical, needle-leaved evergreens that we all think of.
Conifers were some of the first plants to colonize land more than 300 million years ago.
It is one of the finest collections of dwarf conifers in the world; the climate at the U.S. National Arboretum allows us to grow some conifers that hail from areas near the Arctic and conifers that are nearly subtropical and cannot withstand long periods of bitter cold.

Conifers are often large and can dominate the plant life in some ecosystems because their stems continue to expand in width as well as length throughout the life of the plant.
Each scale in the male cone has two sporangia in which meiosis occurs to produce tetrads of spores, just as in a fern sporangium.
Conifer seedlings have several needle-like cotyledons in a whorl and the seedlings produce scattered leaves until adult foliage develops.

Conifers probably dominated the upland forests since the late Pennsylvanian and have continued to be important components of the vegetation to this day.
Florin (1951, 1954) argued that the conifer bract was homologous to the cordaitean leaf subtending the ovule-bearing branch, which he homologized with the ovuliferous scale of conifers.

On each tiny scale of a male cone, a pollen sac develops, inside which pollen grains are formed.
Pollen is carried by the wind, and some of the pollen grains land between the scales of female cones, resulting in fertilization.

 Welcome to the San Diego Wildfires Education Project
The Cedar Fire burned through the mixed conifer forests of the Park in a high severity stand-replacing fire, burning through the tops of the trees and causing high levels of tree mortality, especially among the conifers.
Cones are small (0.8 to 1.5 inches), and hang from the tip of the branch.
While a mixed conifer forest may not recover for many years in CRSP, it is becoming replaced by oak woodland and chaparral, whose species are recovering in the burned areas already.
