North Carolina reaches 10,000 observations!

Yesterday, July 27, 2014, North Carolina passed the 10,000 observation mark! johnratzlaff posted the 10,000th observation. I thought it would be a worthy occasion for some quick statistics-here is where we were in North Carolina when I ran the numbers this afternoon:

Observations: 10,007

Research-grade: 4,529 (45.3%)
Unresolved ID Please: 1,542 (15.4%)

With photo: 9,474 (94.7%)
With sound: 19 (0.02%)
With both photo & sound: 2

Observations of plants: 4,680
Observations of insects: 2,148
Observations of birds: 1,018
Observations of herps: 852
Observations of fungi: 331
Observations of mammals: 210
Observations of fish: 36

Note: I did not figure the total number of species observed, or the number of species observed in each taxonomic group, although I might get to that at some point

Mountains: 3,333 (33.3%)
Piedmont: 4,663 (46.6%)
Coastal plain: 1,785 (17.8%)
Sandhills: 151 (1.5%)

Note: the North Carolina regions in iNaturalist follow the map in the NC Natural Heritage Program rare plant list (which I georeferenced & digitized, although I didn't split out the tidewater region). You'll notice that the total for the four regions above doesn't quite match the total for the state (off by 75, or 0.75%), which I guess is because of edge cases where observations are very close to the state line and the regions as drawn don't exactly match the state boundaries. Looking forward to the 2014 rare plant list coming out soon!

2014 (to date): 5,030 (50.2%), and we still have 5 months to go!
2013: 2,976 (29.7%)
2012: 941 (9.4%)
2011: 286 (2.9%)

Note: this is the year the observation was made, not the year it was added to iNaturalist.

For the competitive, you can see a sortable list of number of observations & number of taxa by user (for NC) here, for 2014 only here.

Update, 7/29/2014:
This morning I worked up some additional information:

Taxa observed: 3,030

Number of observations & taxa by icon group (including # & % "research grade"):
Plantae: 4680 observations (1909 RG - 40.8%); 1509 taxa (479 RG - 31.7%)

Aves: 1018 observations (715 RG - 70.2%); 211 taxa (152 RG - 72%)
Amphibia: 436 observations (257 RG - 58.9%); 81 taxa (49 RG - 60.5%)
Reptilia: 416 observations (283 RG - 68%); 86 taxa (53 RG - 61.6%)
Fungi: 331 observations (109 RG - 32.9%); 122 taxa (55 RG - 45.1%)
Mammalia: 210 observations (141 RG - 67.1%); 41 taxa (23 RG - 56.1%)
Arachnida: 122 observations (60 RG - 49.2%); 47 taxa (18 RG - 38.3%)
Animalia: 96 observations (33 RG - 34.4%); 55 taxa (21 RG - 38.2%)

Actinopterygii: 36 observations (16 RG - 44.4%); 25 taxa (9 RG - 36%)
Protozoa: 8 observations (7 RG - 87.5%); 3 taxa (2 RG - 66.7%)
Chromista: 1 observations (1 RG - 100%); 1 taxa (1 RG - 100%)

Ten most-observed species (13 actually, since there was a five-way tie for 10th):
Canada goose (Branta canadensis): 30 observations
great blue heron (Ardea herodias): 28 observations
eastern tiger swallowtail (Papilio glaucus): 23 observations
flowering dogwood (Cornus florida): 23 observations
pokeweed (Phytolacca americana): 22 observations
Carolina horse-nettle (Solanum carolinense): 22 observations
green tree frog (Hyla cinerea): 21 observations
mountain laurel (Kalmia latifolia): 20 observations
red maple (Acer rubrum): 19 observations
American sweetgum (Liquidambar styraciflua): 19 observations
turkey vulture (Cathartes aura): 19 observations
Fowler's toad (Anaxyrus fowleri): 19 observations
southern toad (Anaxyrus terrestris): 19 observations

I will continue to play with the data and will add what I come up with to this post. If you have a specific question that you'd like me to try to address, post in the comments and I'll give it a shot.

Keep up the good work, and spread the word!
