I would bring back the Dodo, even if people noticed, because there is still a chance to save the Calveria tree (Sideroxylon grandiflorum, formerly Calvaria major), a very long-living species.
There was an hypothesis in the 1970s that Calveria depended entirely on the Dodo to germinate-- the Dodo ate the very hard nuts it produces, the way some birds eat small stones to aid digestion, and in symbiosis, this helped the very hard nuts to crack, so they could sprout.
The picture in the 70s was that the Calvaria was disappearing as there appeared to be no saplings, and few trees from after the time the Dodo officially disappeared.
Since the 70s, it’s been found that some tortoises eat the seeds, and then they can sprout, sometimes successfully-- albeit, not at the rate they did when the Dodo was alive-- and invasive species are crowding out the Calvaria.
The Calvaria is on the “critically endangered” list, heading toward extinction.
Bringing back the Dodo could save the Calvaria, as it could begin sprouting in much greater numbers. The Dodo might not only cause the Calvaria to thrive by being able to compete with the growth of invasive species, the Dodo might also be able to eat some of the invasive species. It will initially look for the endemic species it evolved eating, but as they will be in short supply, it will probably sample the invasive species, and might find some of them digestible. But it helps native species besides the Calvaria germinate, so it will help those others compete with the invaders as well, so there will be greater push against the invasive species.
There is small intervention by people to help remove some of the invasive species in part, as many of the most aggressive ones can be, and are, used as food for people. Those plants and animals used for food are harvested in the wild, not cultivated, because they are so aggressive, there’s no need to cultivate. Unfortunately, there’s not much possibility of export, because of laws about exporting food, but Mauritius has a good tourist industry, and I think, reintroduction of the Dodo would increase it, increasing the demand on the island for these species as food.
Mauritius Island, where the Calvaria lives, and the Dodo would be reintroduced, is the largest island of the (independent) Republic of Mauritius, and is about 3/4 the size of Rhode Island. There are outlying islands the Dodo could get to with modern transportation, footbridges, etc., that were not previously available.
Moreover, the residents and government of Mauritius have enthusiastically endorsed the reintroduction of the Dodo, and pledged cooperation, which is a huge plus.
