Area 2

area2
Area 2 from damaged drain ~ south to turning inlet ~ north

Reason for the grid

Area 2 covers three major problems, which may not be the last, namely
  1. The large patch of Japanese Knotweed (E8)
  2. The failure of the bund by the Japanese Knotweed (E9)
  3. A major break in the bund (F3/F4)
    The southern end of Area2 is 35m from the drain that separates the lower fields Area2 and Area3 or 25m from the damaged bund drain.
