Causes And Cures For Warp In Drying

Lumber warps in many different ways, but all warp is caused by differential directional shrinkage as the wood dries from its green state. When one edge or face or end of a piece of wood shrinks more than the opposite edge or face or end, the piece warps. The three types of warp are cup, bow and crook. Following an introduction to wood shrinkage, each type of warp will be discussed In terms of its causes, likely locations in a log from which lumber might suffer from it, and preventative measures which can alleviate the warping problem, where possible.

Harvesting Pinestraw in Longleaf Pine Stands

Real income potential is possible on many longleaf forests found in eastern and southeastern North Carolina. This Forestry Leaflet explains the typical manner in which longleaf pinestraw is harvested.

Land Ownership, Liability, and the Law in North Carolina

A change in North Carolina law makes it possible for landowners to open their lands with less concern about liability in case of an accident or mishap. It is now possible for landowners to allow the public on their property for educational and recreational reasons, when no fee is charged. Under these circumstances, a landowner is required to provide the duty of care owed to a trespasser. The following note explains the major laws impacting landowners’ liability in North Carolina and the responsibilities landowners have for invited and uninvited users of their property.

Nutrition Management for Longleaf Pinestraw

Demand for pinestraw for use as mulch continues to rise dramatically. This demand has put considerable pressure on existing longleaf pine (Pinus palustris) stands due to frequent removal of pinestraw. While the sale of straw represents a financial opportunity for some private timberland owners, it can be a potential problem because of the repeated removal of nutrients from raked sites.

Producing Firewood from Your Woodlot

A century ago wood supplied most of North Carolina's energy. That share dwindled to less than one percent as energy consumption increased but people switched to coal, oil, and natural gas (much of it used in production of electricity). In the 1970s, steep price increases for nonrenewable fossil fuels led to renewed interest in firewood for domestic heat.

Producing Longleaf Pine Straw

Longleaf pine trees deposit a blanket of needles, often called pine straw, on the forest floor annually. Many forest owners do not realize that it is possible to sell this straw, but in fact wise management of this resource can substantially increase the owner’s income from the forest land. Retail sales of North Carolina longleaf pine straw in 1996 were estimated to exceed $25 million. This volume could easily be doubled or tripled if owners were more aware of this opportunity and if the market were expanded by promoting sales in states to our north.

The State of Our Forest Products Industry

This publication highlights the important role North Carolina’s forest products industry plays in the state’s environment and economy and recommends what actions should be taken to support, promote and grow this industry in North Carolina.

Use Preservative-treated Wood & Integrated Pest Management When Rebuilding

Large areas of land along the Gulf of Mexico have been flooded and destroyed by recent hurricanes. Many homes and other buildings are no longer habitable or will be demolished. Some of these structures will be rebuilt. With this rebuilding comes an opportunity to reduce the impact of a wide array of insects, wood decay and rot.

Wood Identification for Hardwood and Softwood Species Native to Tennessee

This publication provides information on how to identify wood of several species common to Tennessee by using a hand-magnifying lens. Included in this publication are a wood identification key for some common Tennessee species, a list of key specie characteristics and a list of companies that sell wood identification sample sets.

Wood Use and Society

It is not uncommon for people to believe that they use little or no wood in their everyday lives. This is understandable since many products made from wood no longer resemble wood or are used in products not often associated with wood.
