The spring-fed Upper Bedon Stream runs in the open from around TQ490788 to around TQ496780 before disappearing underground. We understand it enters the Thames somewhere in the Erith area.
We have long wanted to conduct an exhaustive Wild Flower' Survey of the immediate surrounding area and think the time has come. We found Ivy Broomrape growing beside the Stream during July-2019 viz.
And last year, we saw Watercress for the first time (making a comeback after previously being recorded and then seemingly disappearing) viz.
