Controlling the terrain is the druid's huge advantage. A druid can be well protected from melee types by casting Spike Stones ahead of time (he scouted with Wildshape, right?) and having his dire bear guard him from melee attackers (or use Wall of Thorns). Make sure you have spells that allow you to escape through trees ahead of time.
