This module uses a variety of available datasets to explore methods of calculating biodiversity and measuring landscape as well as the relationship between those. These points are then used to teach logarithms by estimating slopes and intercepts from a log-log plot of the number of species in a given location against a variety of metrics including island size and distance from mainland. Optionally, this could then be adapted to fragmented habitats near a national park or the like. Finally, the plots are used to estimate the level of fragmentation that would push the system to a given level of species loss.
