How was the CBM used in the Services analysis?
A9: Under contract with the Service, the CBM was applied to determine the particular significance of certain threats . This quantitative analysis calculated probabilities associated with three possible levels of quasi-extinction (100, 250, and 500 adult manatees); three time frames (50, 100, and 150 years); and, six different threats (collisions with boats, hypothermia as a result of loss of warm water sources, drowning or crushing in water control structures, poisoning from red tide [brevetoxicosis], drowning due to entanglement, and the combination of collisions with boats and loss of warm water). The modeling analysis yielded a matrix of probabilities of future Florida manatee population viability for use by Service managers. Under current levels of threats, which include loss of warm water sites, probabilities that manatees would go quasi-extinct on either coast of Florida ranged widely depending on the level of quasi-extinction chosen and the projected future time frame for analys
