What is the most common type of wood used to make paper?

The most common wood used in paper making is the scrap from lumber production, and as to the species...whatever they harvest close to the paper mill is what they use. There are two broad categories of paper: groundwood and free sheet. Groundwood is the old-fashioned kind of paper, and there you really need softwood timber because they make it by soaking wood in water until the fibers come apart. Most groundwood ends up as cardboard. Free sheet is made by dissolving the fibers in chemicals. By the time the wood is sent into the sheet-forming process it's no longer wood but a kind of cellulosic glop, for lack of a better term. They're starting to really like poplar; it's as easy to work with as pine, and it grows so fast you can cut it for paper production in only seven years.

How do I propagate a Yucca Plant?

Yuccas are very easy to propagate. They grow readily from seed and from cuttings.

Seed can be sowed in the normal way.

If your Yucca is one of the trunk-forming species, and it has a number of trunks, just cut one of the trunks about one foot from the lowest leaf. Strip off about half of the leaves, and make sure the cut is really tidy and neat. Brush some rooting powder onto it and leave it to dry for three days to dry.

Put it into a flower pot filled with a 1:1 mixture of compost or peat and perlite. The cut end of the trunk should only be an inch or two deep in the compost. Because it will be top-heavy, secure it in place by tying it firmly to a couple of stakes. Water it just enough to stop it from drying out.

Now all that is reqired is patience - as the developing roots can be damaged if disturbed. When the Yucca starts to produce new leaves examine the underside of the pot to see if any roots are poking out of the holes - this may not happen for about six months. Pot it on into a standard potting compost, and plant out when it has filled its new pot with roots.

Is Camphor Laurel good burning wood for your fireplace?

Though the camphor laurel is a nusicance (or worse) in a number of areas, it's smoke is toxic and it can leave a most unpleasant coating on the inside of your chimney. It probably isn't a good idea to burn this stuff. It's nasty. All the "stuff" in the laurel that allows the production of camphor from its leaves has to get up there, and the trunk (the part you're burning) has a good store of it in the wood. If it isn't against air quality standards in your area to burn the camphor laurel as firewood, it may very well be soon. Heck, they don't even burn it to eradicate it for the most part because of the environmental effects due to the smoke.

Reasons why trees and forest are valued?

Forests and trees are valued for their wood, their replacement of carbon dioxide with oxygen in the atmosphere, the food such as nuts and berries some produce, the shade they create on a hot, sunny day, the pleasant scent of their blossoms, and their beauty. Trees reduce erosion, absorb excess moisture from the soil, provide stability to loose ground, and are the habitat for a multitude of creatures living in their foliage and among their roots.

From a market perspective, trees and tracts of forests are appraised for the value of the timber that the tract has. Value consists of the quality of the wood (straight-grained, free of excessive knots, ring shake, rot, etc.) and quantity. Appraisals are done by foresters to determine the price a (theoretical) willing buyer and a (theoretical) willing seller would agree upon for the trees (and sometimes the land). While it may seem over-simplistic and crass to consider forests in only monetary terms, we all make decisions everyday on the basis of money. And, in order to convince landowners not to sell or convert their forest properties to more profitable ventures the cash value must be known.

How do you remove or wash away urishoil?

There are many natural solutions for exposure to poison oak poison ivy and sumac. The important thing to realize is that urushoil or urishoil is the oil that makes one's skin become irritated from these plants. And a very small amount of the oil can cause much misery for a person who is highly allergic to it. So the important thing to do is get the oil off of you. Remember, this oil can linger on pets, clothes, equipment and loved ones so make sure it is washed off of everything or re-exposure is likely. There is a very popular brand of urishoil remover that is made with mineral spirits or paint thinner and while people swear by its effectiveness it is paint thinner and this should not be overused on the skin. Inhaling mineral spirits and applying it on the skin can cause health issues. Mugwort works really well at removing urushoil from skin and equipment and those who love the outdoors but fear the leaves of three should make themselves familiar with this plant that grows alongside poison oak. Sand, clay and fine earth work well at absorbing urushoil from skin. You can scrub yourself with a handful of fine earth on areas in which your are exposed. Dish soap, baking soda, bon ami, course laundry soap with cool running water get urushoil off as well. Remember if there is an itch- the oils are still on you...scrub them off. Running your equipment and clothes through the washing machine will clean off the oils. Rubbing oil (cooking, olive, almond etc. ) into your skin before you go out in poison oak/ivy country can help seal your skin to urushoil and help prevent the poison oak/ ivy oils from penetrating into your skin. www.libertybotanicals.com/poisonoakremedy.htm
