800 Challenge: 1st Quarter review [Stats & sundries]

No. of species - monthly count







No. of species - monthly count

January 373
February 151
March 128


The declining month on month (M/m) trend is in line with expectations. The more readily-found or common species [easily accessed and or geographically convenient] are added to the list first.

1st quarter target - 675*. Result - 652 [*Zimbabwe trip postponed to 2nd half of 2013]


Species - 1st quarter regional split


Species - 1st quarter regional split









The regional split denotes where a specific species was first seen. Subsequent sightings around the region are not recorded. The bulk of the records stem from areas readily accessed from home. Based elsewhere there is no doubt that the 1st quarter regional split would be skewed elsewhere.



Gauteng 124
Limpopo 66
North West 32
Northern Cape 55
Mpumalanga 224
KZN 65
Western Cape 74
Eastern Cape 0
Free State 7
Namibia 5




Lifers: monthly & regional split
No. of Lifers - monthly count

As expected the bulk of new species seen (ie: lifers / 1st sightings ever) were recorded further afield from home-base. The majority of the lifers recorded were pelagic species (out to sea) - a pleasing result & one of the goals of the 800 Challenge as set out in our founding blog.
