@kitbeard adding one of my observations to the slime/molds project to attempt to get it identified. There are a number of categories where a project aimed at identifying things would be useful but I’ve had trouble finding them when I want them.
This could be useful anytime the best id that I could make was something high level (life, flowering plants) but I know that there is likely to be a small number of species in that category that it could be.
Some things this might be useful for:
Pot plants
Garden plants
Seashore life
Trees
I expect there are more.
Is there a list of these kind of projects somewhere?
WeirdWildWonders (but I only add items there if it’s a real stumper, like something that has been sitting at “Life” for a while with a comment chain indicating people don’t even know what kingdom it might be. That’s a personal choice, though, because I don’t know a lot, and I like to go to this project to solve mysteries, not to add ones that may only be mysteries to me )
Locally to me:
Edward’s Plateau Naturalist
Anything ending in “of Texas” (Plants of Texas, Mammals of Texas, Bees and Wasps of Texas, etc).
I was trying to avoid listing all my many North American, US and Texas projects and mostly post the worldwide ones that are kind of broad (eg, not Stinkbugs of the World, Global Bat Watch, or GeckoWatch, but projects for the “what is that?!” observations, because that’s how I read the initial post).
Of course, that may have been an overly narrow interpretation, and there’s a lot more excellent projects that I have joined just to get IDs on the observations of others: https://www.inaturalist.org/projects/user/star3
You can also find projects by going the “top identifiers” list for a particular taxon, clicking on the profiles of some of the top names, and then viewing what projects they have joined or administer.
As a random side note, there is an amusing semantic difference between the two sides of the pond with respect to plants that live in pots. In the US, they are known as potted plants (in the UK, things that are potted are typically known in the US as canned). In the UK, such plants are called pot plants, which in the US refers to marijuana plants.
Skulls and Bones is for global skeletal remains, and I believe at least New Zealand and South Africa have region specific projects for skeletal remains.
Bird Tracks and Signs is a global tracking project dedicated to evidence of birds, including pellets, eggs, nests, tracks, signs of feeding, bird calls and more. Feathers and bones are welcomed here, but I’d recommend adding them not only to that project but feathers to Found Feathers and skeletal remains to Skulls and Bones as well.
