Confiscated plants go to designated 'rescue' centers, which are usually publicly owned botanical institutions. I volunteered at one, repotting orchids, for 15 years. 95% of the plants received were obvious hybrid dendrobiums and such. All of the confiscated plants were in terrible condition form the delays, and nearly all died. From discussions with others in similar locations I gather the results are similar, with most plants being hybrids (which, I remind you, are NOT subject to CITES) and the death rates for true collected species being nearly 100%, with a few notable exceptions and successes.
CITES has been the most destructive force for extinction of orchids in situ ever.
