One of my small games with my GBS records is to track the cumulative number of species seen GBS-year to date.
This year started off slowly and fell further behind the 10 year average until it was nearly 9 species behind by early September. Since then the additional species have poured in and I'm now 2 species ahead of the average (with lots of previously seen species to add).
I have graphed the two series starting with week (starting week 32 to avoid any complications caused by variations in the timing and duration of our Winter absences).
I usually end up with 75 - 80 species for a year. This year with an ounce of luck, a pound of axle grease and reasonable rainfall I could expect as many as 85 species.
