1M Observations this month

There appear to have been over one million verifiable observations posted this month, which I think is a record. Last year in April seems just under a million and last month was a bit over 700k.

BioBlitz was 4days ago?
I would love to see a graph of statistics.

I think most of them were you reiner!

:P

Looks like you’re correct, @reiner. And City Nature Challenge / the month of April isn’t even over yet…


Here’s the little R script I used to make that fig from the iNat API

library(jsonlite)
options(timeout= 4000000)
dat <- fromJSON("http://api.inaturalist.org/v1/observations/histogram?date_field=created&interval=month&verifiable=true")
x = c()
y = c()
for(i in 1:(length(dat$results$month))){
		x = c(x,names(dat$results$month[i]))
		y = c(y,dat$results$month[[i]])
}

par(mfrow=c(1,1))
xx = (1:length(y))
plot(xx,y, type="l", axes=FALSE, xlab="", ylab="Observations per month", xlim=c(40,length(xx)))
points(xx,y, type="l", lty=2)
axis(2)
axis(1,which(strptime(x,"%Y-%m-%d")$yday==0),(2019-length(which(strptime(x,"%Y-%m-%d")$yday==0))+1):2019)
abline(h=1000000, lty=2)

Here’s an update of obs/month through July 2019. Seems like July is the more ‘natural’ annual peak if you exclude the boost April gets from City Nature Challenge. I expect things will slowly decay to a December low hopefully setting us up for another 2020 spring bump!
