Jim, I share your pain about recovering survey stations. I have been party to several connections that relied on old stations, usually carbided, but few people are equipped to mark such stations nowadays. As you pointed out, flagging tape is obviously not secure due to mice, crickets, etc. White-Out or nail polish seems to hold up well, but physical markers like metal tags or stakes is best. Bolts or even just bolt holes are also good, although the latter can be filled with mud after floods. It will be interesting to see how connections made years or even decades later are verified in the future.
I also share your concern about retaining project members long enough to preserve institutional memory. Not only are leads lost, but the route to leads is also lost. Leads that are obscure or only marginally obvious are especially difficult to relocate, since their significance may not be apparent even after a resurvey. Long-term participation and detailed survey notes and trip reports are key.
