Sample text

The following sections contain descriptive outlines of the major forest biomes we have chosen to discuss. As n o t e d previously, the classification scheme we have chosen to follow is only one of a n u m b e r of possibilities; within that scheme, there will be overlaps between categories as well as gaps in i n f o r m a t i o n - - t h e a m o u n t of i n f o r m a t i o n readily available about each category varies. 2 Global vegetation map showing the distribution of the forest types discussed in this book.

It is interesting to note that plantation forestry is d o m i n a t e d by exo t i c s m t r e e s that are not native to the area where they are cultivated as plantations. Sitka spruce is native to the Pacific Northwest of the United States, where some of the trees grow to great size. Pinus elliottii is native to the southeastern United States, but P. radiata, now so widespread as a plantation species in the s o u t h e r n h e m i s p h e r e , is native to the Monterey Peninsula in southeastern California.

The next critical temperature is - 1 5 ~ and roughly corresponds to frost resistance. The frost resistance of leaves is m u c h lower for broadleaved than coniferous species, with a noticeable m i n i m u m threshold of -15~ (Woodward, 1987). The m i n i m u m temperature threshold for buds is similar for conifers and broad-leaved trees, but broad-leaved angiosperms are more likely to experience ice formation in the xylem during winter. This commonly results in the formation of air bubbles in the spring when the ice melts, thereby r e n d e r i n g the vessels nonfunctional (Becwar and Burke, 1982).
