Do you mean "final to date" or that you don't anticipate ever visiting again? Although I'm sure you'd rue the loss of some species the place has really pulled itself up by the bootstraps in the decade or so since your "last visit".
I pondered whether to put "final to date" or just "final". I decided on the latter as I suspect that will be the case - not because of the loss of any species, just the logistics and cost of getting there.
