Number crunching - what 1000 species might look like

As I approach the end of January with a revised target of >200 by end of the month I sat down and played through the numbers to see what sort of effort would be required to really see this thing through. I have a rough idea of where I'd like to be at the end of each quarter and what the make up of the final list might look like. Will be interesting to see how far off it turns out to be. Targets of course can be revised as time moves along and maybe some groups will do better and others worse than expected. I'll adjust accordingly and target to suit the situation. One thing is sure though - it will require a lot of different techniques to get the job done. I should get the first pitfalls in place by the weekend probably!

Here's a finger-in-the-air estimate of where this is going:


Class Current 2017-tgt %age
Vert - Birds 32 110 29
Vert - Other 1 9 11
Lepidoptera 1 150 0
Diptera 4 125 3
Arachnida 4 61 6
Coleoptera 3 100 3
Invert - Other 26 104 25
Plants - Vascular 36 120 30
Plants - Bryo 11 40 27
Fungi 24 150 16
Lichens 29 55 52
Other 7 11 63

178 1035 17

Edit: some browsing of previous year's totals when this wasn't being attempted. So ballpark I "normally" record about 1000 spp. in a year which I think is encouraging. In 2016 I deliberately focussed on new species and so didn't record many common species I saw.

NT1887, Cullaloe LNR
2015: 773 spp.
2016: 652 spp.

Year totals iRecord - all sites
2015: 1138 spp.
2016: 961 spp.
