Do you buy firewood? If so, make sure you're getting firewood that is pest-free. In
Arkansas, hardwood firewood has been quarantined because of the emerald ash borer
(EAB). This means that it is illegal for you to move any hardwood firewood out of
the state without complying with federal EAB regulations.

Any wood will burn, but different types of trees have different wood characteristics
related to fuel use. The potential heat content, burning characteristics, and overall
usefulness as firewood varies widely across tree species. Of these characteristics, the heat value or the amount of heat generated by burning
the wood is the most important when selecting firewood. Table 1 below outlines the
characteristics of Arkansas trees for firewood. The species include hickory, black
locust, oak, and honeylocust with an excellent overall rating. Species rating very
good include American Persimmon and white ash. Maples have a good rating, with pine
and Eastern Red cedar rating fair, and willow and cottonwood trees are rated poor

Heat value is measured in British Thermal Units or BTUs. This is a standard measure
of heat such that one BTU is equal to the amount of heat required to raise the temperature
of one pound of water one degree Fahrenheit.
The heat value of wood depends on its density and moisture content, or the amount
of water in the wood. The drier and more dense or heavier the wood, the more heat
is released when properly burned. Hardwood trees tend to be denser than softwood trees.
Best Types of Firewood Trees (more dense wood):
The table below shows data which rates species by heat value, how easy the wood is
to split, how many sparks and smoke it tends to produce, and how well the wood produces
long lasting coals. Hardwood trees with dense wood tend to be more highly rated.
(mill. BTU per cord)
Other wood characteristics are also important to consider when deciding which firewood
to use in your home. How easily is the wood split? This is important because large
pieces of firewood will not burn as efficiently as smaller, split, pieces. Splitting
the wood exposes more surface area and allows the wood to dry faster.
The wood's fragrance and tendency to smoke or throw sparks are also important, especially
when burned in a fireplace. Sparks from an open fireplace can be a fire hazard. Pine
tends to spark more than oak because of its high resin content and is therefore not
recommended for use as firewood.
If you are buying firewood and you want to use it soon, make sure that you buy seasoned
firewood. "Seasoned" refers to letting the wood dry to reduce the moisture content.
Seasoning can take from six to nine months depending upon the moisture content of
the wood when it was cut. Trees that were dead standing have lower moisture content
than standing live trees and therefore will not require as much time to season.
A simple method to determine if your firewood is dry is to strike two pieces of wood
together. A sharp cracking sounds means that the wood is fairly dry. A dull thud,
however, means that the moisture content is still high. Dry wood will also display
cracks or "checks" in the end grain along the cut surface.
Although people are accustomed to buying or selling firewood in several different
ways including by the truckload or the rick, the only legal standard is the cord,
fraction of a cord or cubic meter.
Arkansas passed a law in March 2001 that essentially adopted the Uniform National
Standards. The law states that firewood can only be sold by the cord, fraction of
a cord, or cubic meter. The Arkansas State Plant Board administers the law regarding firewood measurements through the Bureau of Standards.
The most common problem is that burning wood causes creosote to form in stovepipes,
chimneys and exhaust systems. When wood or any organic material is burned in a stove
or fireplace, volatile gases and vapors are produced. These gases and vapors are carried up the stovepipe or chimney where they condense
and form creosote.
Creosote is combustible and can cause chimney fires if not periodically removed from
inside the stovepipe or chimney. Creosote in the upper part of the chimney can ignite
and set your roof on fire.
Certain species, including pine, have more potential than others for producing creosote,
but the amount of creosote depends more on the type of fire and the temperature of
the chimney surface. A smoldering, low-temperature fire will produce more creosote
than a roaring high temperature fire. Burning wet or green wood can also create more
creosote. Creosote problems can be minimized by burning well-seasoned wood, making
small, hot fires instead of large smoldering fires and cleaning the chimney and stovepipes
Burning firewood as supplemental heat, a primary source of heat, or periodically for
pleasure is possible if you exercise common sense. Pay attention to what you are buying
or cutting. Make sure that it is seasoned and ready to use. Take precautions to prevent
