In Halton Region forest there is a Crested Wood Fern growing in a tree hollow. It is quite an attractive sight, and on five different occasions people have uploaded observations of this one fern!

Just shows how popular iNaturalist has become.

Makes me wonder what the biggest example of this is, where many people have incidentally noticed the same organism.

I was curious about what areas were over/under-represented in iNaturalist observations, so pulled together some quick data and made the following table for US/Canada.
A few things are interesting:

• Vermont is ridiculous, but the rest of northern New England and the maritimes do very well too. But southern New England (Connecticut/Rhode Island) and Newfoundland are way down the list
• The two jurisdictions with lowest level of use are also the two where English is not the primary language
• My home province of Ontario does very well, with the only large jurisdictions doing better being California and Texas

And on a map (dunno why Nunavut and Prince Edward Island are all screwed up)

At the beginning of the year I posted on my external blog about my goal to photograph 1000 species for iNaturalist in Ontario in 2018. At the time, I thought this would be a bit of a challenge. We're now sitting exactly halfway through the year, and I wanted to write a quick post about how it's turning out. Here's my numbers up to June 30:

602 plants
172 birds
53 dragonflies and damselflies
38 butterflies
19 mammals
13 amphibians
12 reptiles
23 other organisms (fungi, fish, various insects, etc.)

For a total of 932 species!

It turns out I seriously overestimated how difficult this would be. I think the main surprise is how many species of plants there are. It doesn't really feel like I've seen over 600 species of plants this year, but the numbers don't lie.

So what's next? I'll probably hit the 1000 species mark in the next week or two depending on how much effort I put in. Past that, I expect I'll finish the year somewhere between 1200 and 1300 species.

I've made this same post on my external blog and included photos of some my favourite sightings of the year:
