If a Dicksonia then with this mild weather I am not protecting mine at all and they are pushing out fronds. I only wrap if a hard frost is forecast.
Wet and freezing is not good, but neither is dry and dessicated. In Oz they grow in forests that freeze and are very damp (but you cannot compare a few hours of -10 then 15C) with -3 then 0C in the UK.
I also do not use straw but use Eucalyptus and other tough leaves like broken up Laurel to insulate and keep the crown damp.
