Table 1.

The area required and costs associated with representing a target of 10% of the geographic range of each mammal species with and without socioeconomic objectives

Study extent	Socioeconomic objective	Area required to meet targets	Cost of meeting targets
All	None	18.4 Mha	2.2 Mha cropped land (12% of total priority area is subject to cropping)
	Minimize area cropped in priority set	18.8 Mha (increase of 2%)	1.1 Mha cropped land (6% of total priority area is subject to cropping)
Potential conservation habitat	None	17.84 Mha	1.5 times minimum opportunity cost
	Minimize opportunity cost of the priority set	18.21 Mha (increase of 2%)	Minimum opportunity cost

Areas of intensive use are excluded when employing the opportunity cost layer as it represents the cost of forgone production in areas of land that are not under intensive use (hereafter “potential conservation habitat”). Hence scenarios with differing study area extents are not comparable.
