Dragon's Blood is a resin produced by a pretty large variety of species in a few genera, but is mostly cultivated from a handful of species in Dracaena and Calamus (formerly Daemonorops)

While historically the endangered Dracaena cinnabari and Dracaena draco were somewhat common sources in the incense trade of antiquity, today the majority is from rattan palms like Calamus rotang or less commonly (although seemingly more commonly in marketing) from Calamus draco which are extremely common and widespread across Asia, Africa, and Australia. The likelihood of getting something from an endangered source is slim to none.

(As always, happy to answer further taxonomy and botany questions, especially if this isn't a sufficient answer)

I don't know for sure, and I don't think that anyone could without a genuine non-Kimberley/non-Fair Trade/other bogus certification process in place, but it appears as though most dragon's blood resin that is commercially available is harvested from the fruit of a type of rattan palm.

(That's operating on the assumption that dragon's blood incense isn't a synthetic fragrance that has been developed to mimic "genuine" dragon's blood incense at a lower cost of production.)

It's hard to know a lot about this production process but if you're harvesting the resin from the fruit of a tree then that's more sustainable for habitats since you aren't harming or cutting the trees themselves down. It's hard to imagine a stable supply chain that sources all of its dragon's blood resin from threatened dracaena trees on Socotra without it coming at a hefty premium that would make your eyes water at the cost of true Socotran dragon's blood resin incense, especially if a country like Indonesia can mass produce a very similar resin in a relatively sustainable way.

I'd withhold judgement until you get more solid information but, at a wild guess, I think that it's probably not a huge concern.

Also note that crunchy stuff like this loves to market itself as being produced from ingredients from exotic locations by native peoples from some rare source that is of spiritual/cultural/environmental significance. Himalayan sea salt invokes notions of Tibetan Buddhist monks using hand tools to mindfully carve out small amounts of magical, spiritual salt from traditional meditation caves because of the conscious choice of labelling it that way. It doesn't invoke notions of Pakistani Muslims using modern machinery to carve out huge blocks of salt from their salt mines because people are less inclined to give salt mined that way some aura of faux-spirituality and reverence due to that dualistic nature of orientalism ("Eww, yucky brown Muslims are dirty and sneaky and untrustworthy!!"/"Wow, those Asian Buddhists are so noble and glorious and spiritually in tune with compassion and the environment. So wholesome!!" – both are gross and interdependent in a dialectical sense imo, although one is much more benign than the other.) I would view any information on the back of a product that is marketed to a crunchy demographic with deep skepticism personally. There's basically no regulations about whatever bullshit fairytale a product like this can spin. Yay capitalism!

Wikipedia is a marginally better source than the seemingly LLM written articles on the topic

It appears that the resin is harvested from a number of different plants, not just d. cinnabari or d draco the threatened ones. If you could see the ingredients of the incence you're getting it may say what species it's from...
