RPA with Dykes and Ditches

[Stuart Picken]

Hi Folks,

Thinking about root protection areas. 

I was on a site yesterday looking at some trees that were sandwiched between a field and a road. Unfortunately I forgot to snap a photo, so i've done a wee dooble. Hopefully it's clear enough.

 

So my wondering is, in a case like this where do the roots go? The arable field has clearly been plowed in the recent past. Would it be fair to guess that the roots are confined to the raised dyke, and under the ditch?

And if people were carrying out a BS 5837 for example, would you restrict the RPA accordingly?

 

Let me know what folk think!

If you can fit in the RPA between the road and the outside of the ditch by elongating the RPAs parallel to the road/ditch then I'd probably do that. Whether the roots (the important ones, remember the RPA is not the same as the rooting area) to under roads, under ditches and aunder ploughed fields depends on species, soil type and a load of other things.
