I recently read this article. It discusses how we can use statistical methods to provide estimates of species population given little information about the actual population and other factors that make up the ecosystem. This is all fine, and i understand the importance of obtaining information about a system given limited information on initial conditions etc. What i'm not sure i understand is the importance or significance of obtaining an estimate of a population of species, in general. The article talks briefly about how knowledge of this information would allow us to know how much wildlife would be eradicated in deforestation. and also about preserving said wildlife. Which i suppose is pretty significant in and of itself. Maybe since it is not my background i am failing to see that this is indeed very important. But for what it's worth, is there anything else?
