How things Changed on the River Irwell 27 Jun 15

I was in Bury by the Irwell today, the change in the river bank over the last few months is amazing.

  The pictures above were taken on 8 April, the ones below are from today.

The white on the bank top left are the same flowers as the white ones below.

 I think nature has done a good job, but there is a  problem 3 non native invasive plants are also growing along the river bank, Giant  Hogweed, Himalayan Balsam and Japanese Knotweed  . 

Hard to believe it's the same place.
