Excerpt from Genetics of Longleaf Pine These extensive stands were easily exploited, and near total removal devastated much of the resource, leaving only scattered trees or sparse stands to supply seed for natural regeneration. In addition, large areas were cleared for farm ing. By 1930, the volume of longleaf pine was estimated at one-tenth the original.

Excerpt from Genetics of Pitch Pine At various times, pond pine was considered a variety of pitch pine and until recently was included in standard texts as P. Rigida var. Serotina (michx.) Loud.

Excerpt from Genetics of Virginia Pine Pinus virginiana (mill), variously known as Virginia, Jersey, possum, spruce, short straw, scrub, poverty, and old field pine, is a species of contrasts. It is despised by the logger but liked by the forester and the pulp mill manager in most areas of its range. The logger's negative reaction to Virginia pine results from the tree's small size and to its persistent branching habit, factors which adversely affect harvesting production. Dominant and codominant trees average only 23 to 25 meters tall and 28 to 30 centi meters at 50 years.2 Older trees may attain heights to 35 meters and diameters to 90 centimeters (harlow and Harrar but even they often retain branches and branch stubs the length of the bole below the live crown. Despite these deterrents, the species has gained the respect of foresters because of good volume and dry-weight yields at rota tion ages of 25 to 30 years (newland 1968, nc. State Univ. And of pulp mill managers because of suitability of the fiber for fine paper and groundwood products. These attributes are responsible for a recent planting program of several thousand acres annually. Secondary uses of Virginia pine include lumber and structural timber from sawlog-sized trees, and Christmas trees which are harvested at rotation ages of 6 to 10 years. This paper reviews the current status of research on the genetics of, Virginia pine. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Genetics of Jack Pine Jack pine is an important species for planting and direct seeding in the Lake States and throughout much of the boreal forest of Canada, where it is a major source of pulpwood, lumber, and round tim ber. It is highly variable in climatic adaptation, growth, and form and exhibits great genetic diversi ty of silvicultural significance. Although referred to early in the 2oth century as a frugal scrub, its cur rent high economic value, genetic variability, silvi cultural simplicity, and ability to grow on less fer tile and drier soils than are required by other sym patric species make jack pine a prime candidate for genetic improvement by selection, breeding, and controlled seed production. Jack pine is in the Subgenus Pinus, Section Pinus, and Subsection Contortae along with lodgepole pine, Virginia pine, and sand pine.
