It's good that the rainwater here is not flowing downhill into the lowlands. But that has to be expected given that the land at this point is fairly flat. At other parts of Blacka trees have been felled on slopes creating open areas and allowing more run-off after heavy rain, not by any means good practice.
The part illustrated was a narrow path which never got like this. All changed when cows came along; they would walk along here in the morning as regular as clockwork eating the grass to each side and in the course of their activity widening the narrow path to take on the look of a wide track. There were one or two small trees that helped to soak up the excess moisture that gathered but they were cut down by conscientious SRWT people. Hence the swamp.
We really love 'em.
