part 1: data compilation

1. Calculate Im to the nearest whole number for the last ten stations in Table 14.2 using equation 1.

2. Locate these same ten stations at “x”s on the maps of ecoregions (Figure 14.2) and soil orders (Figure 14.3). Record the letter codes representing the vegetation and soil at each station (Table 14.1) to complete Table 14.2. For mixed vegetation, use the first type listed in the ecoregions map (Figure 14.2) key.

TABLE 14.1 Vegetation and Soil Codes

Use:	For:	Use:	For:
R	Tropical Rainforest	s	Spodosols ("ash-colored")
B	Broadleaf temperate forest	a	Alfisols ("aluminum & iron stains")
N	Needleleaf forest	m	Mollisols ("soft & friable")
S	Savanna	u	Ultisols ("old")
G	Grassland	o	Oxisols ("oxidized")
D	Desert	v	Vertisols ("turning over")
T	Tundra	h	Histosols ("tissue-like")
		d	Aridisols ("dry")
		e	Entisols ("recent")
		i	Inceptisols ("beginning")
		v	Andisols (“volcanic andesite”)
		g	Gelisols (“gelifluction & frost heaving”)
