Plastic sheeting on bank at side of Motorways???

While travelling up and down the country I noticed there are sections of the bank that have 18inch high clear plastic sheeting on it sometimes for several miles?





Bugging me like mad, any ideas?Plastic sheeting on bank at side of Motorways???
It could be an area where newts are and they are protected creatures .


They are probably doing work there on the embankments so they will have to save as many as they can.

Can't say I've seen it, but it sounds like weather deflectors, (e.g. snow)
i often wondered that i just assumed it was seeds or very young trees just planted %26amp; its to stop the birds getting at them.





but i may be wrong
probably protecting young plants from cold weather.
might be if the bank is loose to hold it in place
