staghorn fern plant in metal cage (south sunnyvale)

we've been growing it for 25 years approx. had it hanging from a black walnut tree in our front yard. tree got diseased and finally just fell down couple weeks ago. fern is in a metal cage that's by now enmeshed inside the bark. it's real big. you can take part of it.
