So being new to this game I am keen to learn what I can.
In my quest for knowledge I have found the BDS distribution survey maps.
I note that they have survey maps from 2000 and 2009.
The first thing that struck me is that the population distribution of all 6 species has spread over this period.
Does this mean that the population is growing or that the population is spreading?
