A number of parcels are available for purchase (in whole or part) and you have been hired to make a recommendation about which parcels to buy. (For related real examples, see Bren Group Projects from 2000 and 2003 ). In a map of the river below, these parcels have been indicated along with the values of C (cost per hectare in thousands of dollars), L (LBV habitat index) and F (TTF habitat index). Each parcel is 100 hectares in size (1km 2 = 100 hectares). The habitat indices may take on a value of 0, 1, 2 or 3, with 3 being the most suitable habitat. The probability of a species surviving is proportional to the square-root of being the most suitable habitat....
