Tracheal intubation. Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs.
Shade â Moss also likes to grow in the shade, which makes sense as moisture is more likely to linger in these areas and the moss will be less likely to dry out quickly. Acidic soil â Moss also likes soil with a higher acidity, normally soil with a pH of about 5.5.
Mosses on trees are almost always accompanied by lichens. Fortunately, mosses and lichens are generally not harmful to trees and often look attractive. But, according to at least one source, wet mosses can be heavy and making trees susceptible to wind damage (Rost, 1998). On the other hand, tree care businesses say they get few requests for moss removal from trees and shrubs and that it is rarely necessary. Consider the underlying causes of prolific moss growth. Generally mosses will be most developed on older landscape plantings under conditions of diffuse light. With more direct sunlight and air circulation around trees and shrubs, lichens are favored instead of mosses.
