Depending on your proximity to large mature trees, one should assume nearby roots will try to enter your buried downspout drain pipe for the steady source of water it provides. Any small drainage weep holes or connections left unprotected may be slowly overtaken by a thirsty tree's roots, unless precautions are taken.
ALLOW PROVISIONS FOR WATER TO COMPLETELY EMPTY BURIED DRAIN PIPE
To start, it is always a good idea to create multiple exit points for any/all water left in a buried drain pipe to completely empty out, over time. This will help avoid common frozen pipe issues stemming from standing water in drain line.
PROTECT YOUR SUB-SURFACE DRAINAGE OPENINGS
Any drainage weep holes created or inherited in a buried downspout drain pipe system should be protected by wrapping a quality non-woven fabric around the penetrable components before backfilling to ensure water can evacuate, but roots and small debris cannot easily enter buried drain system.
Of course, it is always a good idea to clean your buried downspout drain pipes and basins once a year (minimum). This routine annual cleaning process will also allow for a quick inspection to ensure your buried drain system is functioning as intended.
