Oak

This oak is at a local park. I am interested to know what has caused the decline.

 

Surrounding trees appear healthy. Branch tips all dead but lots of new epicormic growth, very slow to start growth this year compared to the surrounding oaks.

Difficult to say, and probably a multi-factor thing - the epicormic is "last gasp" I would suggest.
