Please help me to understand out the structure of the following sentence:




> if appropriate, you should consider formulating national and regional
> action plans, incorporating timetables, targets and provisions for
> funding, designed to enhance enforcement of CITES, achieve compliance
> with its provisions, and support wildlife-law enforcement agencies.

Here, I don't understand what "designed to enhance..." is.
Is this modifying something before the phrase?
Or is it acting like an adverb?
Please help me.
