Perhaps more than anything else, the sec- ond edition's purpose is to dispel these misconceptions.

These patches of dense forest within a more open matrix of E. camphora vegetation across the Reserve may not be even-aged. Rood or severe windstorm may have resulted in patches of younger forest becoming estab- lished.

Most trees in the reserve regenerated in a major recruitment pulse in the late ISOOs (Parks Victoria 1997; Parker 1999), st) the similarity in tree girths indicates that both colour forms have grown at the same growth rate throughout this century.
