12/10/2010 Biodiversity Slides 4 Notation: i = a specific project designed to protect a target species. B i = Biodiversity value of species protected by project i. U i = Use value of species protected by project i, if preserved. C i = Cost of project i. P i (0) and P i (1) indicate the probability that the species will survive without (0) and with (1) project i. P i = P i (1) - P i (0): Change in probability of survival caused by project i.
