Captive Born to Wild Release.

I saw some old posts about this and questions some folks had. Captive born tarantulas can easily be reintroduced to suitable habitat. They are instinctual creatures, non of their behaviors are learned like say a Whooping Crane needs to learn how to migrate back and forth from summer breeding ground to overwintering areas in the fall. However young spiders have a very high mortality rate in the wild due to predation and the environment.

Something like reintroduction of some vulnerable species could be viable if a few criteria are met:
1) Habitat has to be suitable and not so fragmented to make wild reintroduction a viable option.
2) Local government and populace needs to be educated on the benefits of the reintroduction.
3) some type of voluntary sling donation arrangement needs to be defined to the benefit of captive breeders, the reintroduction and the health of the Ts
4) Probably the hardest, a central and local location needs to found where slings can be quarantine prior to release to monitor any diseases of parasites prior to release. Ideally this would be staffed and ran by local volunteers.
5) A reintroduction site for the lings must be located where easy monitoring of the slings can take place.
6) Some slings should be raised to adulthood to reintroduce mature spiders that can begin breeding right away.

Sling donation can be up to the breeders, but a good number would be 3-5% of total viable slings. Of course this is negotiable by species due to differences in birth rates and number of eggs per sac. Also setting up a breeding project at the centralized location can remove some of the burden from breeders. However the beginning of such a local breeding project would require some initial sling and sub adult donations to get off the ground in a good way.

Just some thoughts, but something like this could easily be done if organized correctly at the local level. Some of this may require international permits due to import and export restrictions on vulnerable species. All of this can be worked out if a well thought out project is presented to the governing authorities.

I think it would be cool to do for species that have been over collected.

i think there needs to be another stipulation though.

7) Species genetics MUST be verifiably pure and introduction should only be of native species.

EDIT: i also suspect that there would be greater success releasing either large slings or juveniles. the mortality rate would probably be notably less.

Thank you. Totally forgot about hybrids.

I have some experience with reintroduction. Part of my undergraduate studies included helping restore a riparian stream and a tall grass prairie at the The Ohio State University Lima campus in their Tecumseh Natural Area.

Yeah, hybrids in the hobby are bad enough, destroying the wild bloodlines would be infinitely more tragic...

Their is some wild hybridization, but it is extremely rare. Most hybrids in the wild tend to be heavily predated.

People have done it, but they took the parents from the wild - they didn't come from breeders. Then, there are those who have taken a gravid female out of the area and put her spiderlings back close to where she was found. Both of those reintroduction scenarios are feasible.
Many of the species that we have in captivity could never be 100% confirmed to not be hybrids. Buying a tarantula from a breeder for reintroduction purposes would probably do far more harm than good.
Also, the number who would survive in the wild would be a fraction of the eggs that developed. In order for reintroduction to be successful, you would have to be reintroducing literally thousands for a significant amount to grow to maturity. They have no protection in the wild and the vast majority would not make it.

I would assume most places would also require permits to do so...permits which might not be so easily handed out.

Big corporations and deforestation is just as big of a threat as the pet and atarentula food trade in Asia killing off valuable haplophelmas.
I think this could work but you might as well put all Ts on cites , and outlaw the capturing of them and eating.
You would need a standing army to enforce it tho , smart plan! It’s been done with a few species of animals right??
Very few would survive and It might take more then hobbyists to save a dying breed in wild , still possibile.
