Thanks, @thomaseverest! I read the thread that you linked to, by Matt @muir. Matt @muir also shared this list of backyard projects: > [@House of a thousand species](https://forum.inaturalist.org/t/house-of-a-thousand-species/47407/14): > > If you’re comfortable sharing what you see around where you live, you should! And if and when you do, you should consider adding your project to this umbrella grouping of people doing the same at their homes and properties: [https://www.inaturalist.org/projects/home-projects-umbrella](https://www.inaturalist.org/projects/home-projects-umbrella) If you sort that list by number of species, and you take out the top one (because it is a farm, rather than a house and yard), it looks like the species record is around 2,000 species, which was hit (or nearly hit) by multiple people. But they’re not sequencing DNA, and they’re not looking inside water or soil. > [@House of a thousand species](https://forum.inaturalist.org/t/house-of-a-thousand-species/47407/41): > > > [@House of a thousand species](https://forum.inaturalist.org/t/house-of-a-thousand-species/47407/19): > > > > They apparently did not bother to check for plant pathogens - they should’ve found dozens of (true and false) mildew and rust fungus species on both wild and ornamental plants.

ID-ing of any of those things with any degree of certainty would’ve required, at the bare minimum, a compound scope with 100x magnification, assorted stains and slide preps, and ideally ability to make cultures and sequence DNA. As a researching taxonomist I theoretically had access to all those things, but 1) we were directed to evacuate work and lock down at home with very little notice; 2) there were misgivings about starting up a whole lab at home, not to mention OHS restrictions; and 3) we actually didn’t think to undertake this project until after lockdown had commenced (on day 1, after we were already stuck at home). It’s also worth noting that stuff like that blows out very easily. Microbiomes are incredibly complex, with lots of species/taxon complexes, strains and symbioses. > [@House of a thousand species](https://forum.inaturalist.org/t/house-of-a-thousand-species/47407/33): > > Our rules were that each species had to be identifiable as an organism with the naked eye Cryptic species are not identifiable with the naked eye. What if you have 10 nematodes in a spoonful of soil, that all look identical, but are revealed (through DNA barcoding) to be 10 different species? If you’re willing to send DNA for sequencing, use a microscope, etc., then you should be able to double this 2,000 species number, at least?
