In the fruit and vegetable product industry, chlorine is commonly used to remove microbes such as bacteria and mold from produce. In the home, a water wash, either with or without the help of a produce brush, is typically used to clean fruits and vegetables.
57 ALPINE ZONE The alpine zone occurs in high mountain areas where the mean annual precipitation is above 41 inches and the RET is the lowest in the state (Figure 7.6). These areas occur above the upper timber line. The vegeta-tion consists mainly of small cushion plants on rocky slopes.
Above the tree line, alpine vegetation comprises a variety of different subtypes including grasslands, mires, low heathlands, and crevice-occupying vegetation. For example, treeless alpine vegetation is found on mountains above 2,500 metres in central Japan, grading down to 1,400 metres in northern Hokkaido.
