Would it work any better for you, Julie, if it were "partly" instead of "partially"?
If part of a building is destroyed, but the rest of it is intact, then the whole building could be said to be partly destroyed. No?
A forest fire can easily destroy only half a forest, leaving the rest unharmed.
Without source or context, we don't know whether the OP meant that some but not all of the homes/forests were completely destroyed (partially applies to the number of homes), or whether some or all of them were destroyed "incompletely" (partially applies to each home/forest).
