I have a large birds nest fern (Asplenium nidus I think) which I am
moving to a new property. The proposed new location is near a river
bank. This river floods from time to time. In a big flood the site
will go under water, local knowledge cannot say accurately how ofen this
will happen or how long the water will stay up in such a flood. At a
guess every 5 years and for about 2-3 days. The site will not be
subject to physical damage from the current or floating logs. I am
trying to assess whether this site is a reasonable risk or not.

My question is how long will the fern survive if immersed?

Probably not several days. Look at the bank where you propose to
plant this fern. How old are most of the plants, and are they
pretty much roots-in-water-tolerant? If it's less than the
timing of the last flood and / or yes, pick another spot for the
fern.
