Unformatted text preview: ESM 204 Assignment 1 Reserve Siting for Species Viability The Santa Cruz River Preservation Trust (SCRiPT) has received a grant of $20 million to purchase land in the vicinity of the river to enhance the ecological integrity of the river. There are two species of particular concern in the vicinity of the river: the Least Bell's Vireo (LBV) and the Toasty- throated Frog (TTF). Some locales are better than others for these species. 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....
