Citizen science on land changes

I've come across a couple of good citizen science opportunities recently, both of which simply involve taking photos and posting them to the appropriate app/website.

The first is one looking at the regrowth of plants and animals in the zones devasted by the recent (and still on-going) bushfires in Australia:

"If we can just get lots of eyes on the ground we can look at the fire intensity and what the plants are doing."
The study's webpage, with currents results: https://www.inaturalist.org/projects/environment-recovery-project-australian-bushfires-2019-2020

The second, again in Australia, but which has also spread globally, is Coast Snap. This project is looking at the changes to beaches over time
https://www.environment.nsw.gov.au/research-and-publications/your-research/citizen-science/digital-projects/coastsnap
"CoastSnap data provides a valuable record of the movement of sand between the exposed and submersed parts of the beach system. Coastal researchers and managers can use that data to investigate how much the beach might change during extreme conditions, or in response to the long-term effects of climate change such as sea level rise."
If it's of any favourability, this one even has a Facebook page, which you can post to and see information from the global snap points.

The page above also lists and links a few other citizen science projects.
