Since you all were as excited about my last visualization about milkweed bug misidentifications as I was, I thought I’d share one I put together about invasive species. This one takes a place_id and plots the introduced species as bubbles sized by the number of research-grade observations in that p…

There’s almost certainly a bias towards observing the more charismatic taxa. For example Rosa rugosa is definitely not the most abundant nonnative plant in Acadia National Park, but it makes pretty flowers so it grabs folks’ attention.

Yes, and if you plotted them by month, you can see changes in the bias as things start and stop flowering or other activity [introduced_species_of_Acadia_National_ParkMay] [introduced_species_of_Acadia_National_ParkJune] [introduced_species_of_Acadia_National_ParkJuly] [introduced_species_of_Acadia…

Do you mind explaining how to use this? I’m not very computer savvy. I get the impression I need R?

Of course! So to run this code you need to have R and Rstudio installed ( https://cran.r-project.org/ , https://rstudio.com/products/rstudio/ ) If you don’t want to mess with downloading, you can also run code in your browser here: https://rstudio.cloud/ Copy and paste the code into the scripting p…

I’ve been trying to work through all the error messages I got, but I really don’t understand them. I think it is not installing the packages in the first three lines, but I don’t know why. I guess this just isn’t for me, which is a shame because it looks cool.

hm. Try copying the code from here, I uncommented the first few lines directly: install.packages("tidyverse", "devtools", "ggraph", "packcircles") library(devtools) devtools::install_github("hrbrmstr/curlconverter") library(curlconverter) library(tidyverse) library(ggraph) library(packcircles) pl…

I think that would definitely be a big factor. In my area we are up to our ears in robins, yet multiple ranks above them in observation numbers are great blue herons, which you are generally considered lucky to see. So of course the robins are ignored and the herons are sought out and rigorously pho…

i wonder if this could be made a little more efficient if it hit the observation species count endpoint (ex. http://api.inaturalist.org/v1/observations/species_counts?introduced=true&place_id=1&quality_grade=research ) instead of pulling in all observations? (i suppose the downside of using the speci…

Yep, this is a good point. And the children/subspecies taxa was the thing I was going for most (but there is definitely a speed tradeoff and your proposed method will perform WAY better with large places).

So far the most visually pleasing one I have made is the plants of Tucson, AZ
