Spring bounce and numbers

The species per day total is starting to reflect the spring bounce, with March a hiatus between the counting of the winter and "ever present" species and the beginning of the spring emergence of plants and animals. Or maybe that's an overanalysis. Anyway, long may it continue. An average of three species per day really ought to be quite manageable for the next few months.






Date 31-Jan 28-Feb 31-Mar 13-Apr
days remaining 334 306 275 262
species so far 236 337 419 454
species/day period 7.61 3.61 2.65 2.69
spec/day so far 7.61 5.71 4.66 4.41
species remaining 764 663 581 546
spec/day rqd 2.29 2.17 2.11 2.08
spec/week rqd 16.01 15.17 14.79 14.59

I finally got aruond to incorporating this year's totals into the ones from the end of last year, showing a total of 573 species for the square.
