as long as it’s done in a sustainable way and in a generally tasteful (not vulgar) way, i don’t see any problem with a carved wooden board of a pine tree as one piece of evidence of the organism. i wouldn’t encourage chopping down trees just to get an observation like that, but suppose a big tree was going to be taken down as part of construction. if you got a photo of the tree before and after, and you were also able to get a section of the tree trunk, and if you took that tree trunk section and turned it into a nice table or some work of art that showed off how many rings were in that big tree… i think that would be a nice way to observe and memorialize that tree (though it would be sad that the big tree was taken down).
maybe the concern is that the fungus is destroyed as part of the observation. my impression from the mushroom comments on this forum is that taking the fruiting body is generally not a problem for the organism, since the fungus will still exist in its substrate. it’s true that the next person will not be able to see the fruiting body after it’s gone, but a new one should emerge in time.
in a way, i think the revelation of interesting characteristics of various organisms may help some to appreciate nature even more. that’s not just a nondescript fungus. that’s a fungus that artists have used over the centuries to make interesting art. and if that helps to engage people with nature more than a simple picture of the fungus on the tree trunk, then the artist bracket observation seems to be ok to me.
i think this is a slippery slope. if you create a filter specifically for “artisitic” content, then why shouldn’t there be a filter for animals that have been tagged or banded, or why not a filter for insects that have been caught in a net or a light trap, or why not a filter for plants whose flowers have been plucked and dissected to show the interior structures? any of those activities executed badly could be a model for bad behavior, but done well can help advance our collective knowledge and appreciation of nature.
you can already create an observation field to note “artistic” content or put such observations in an “artistic” project, if you wanted to. from there, you could filter out those observations based on their inclusion in that project. and you can flag bad observations outright. i think those existing tools provide you the options you’re looking for.
