I’ve started to obscure a lot more after hearing about some rare plants (orchids) poached likely after a friend put up an observation of them among others (with the other observations unobscured). I also obscure areas of sensitive habitat. Conservation is worth it. The location is still logged and any researcher that really needs the information can be vetted.
Here is some good info on the subject… https://www.researchgate.net/project/BIOSEC-Biodiversity-and-Security-Understanding-Environmental-Crime-illegal-wildlife-trade-and-threat-finance
I am wondering why all cactus are not obscured automatically.
Because not all cactus are a poaching risk. Some are even invasive species in some places.
