| Radlett Road | |
| Travelling north from the Euston-Birmingham mainline Railway
bridge on Radlett road the view to the right is an uninspiring series of football and rugby pitches although
the coleopterist will immediately be aware of a series of large willows and polars in various conditions
of health flanking the road. This continues for a mile or so until Bushey Mill road is reached. But following the railway
embankment east from Radlett road for a quarter of a mile a footpath will be found which, turning left, will take
you north. This pathway (optimistically) marks a boundary to the river Colne floodplain and it is between this
pathway and the river which will prove interesting to the coleopterist. Walking north the vegetation is rich
and varied from mature Crataegus and Fraxinus (etc) to extensive Iris beds along the river.
Beyond Colonial way are a few acres of mature reedbeds currently(2008) invading the river Colne feeder ponds
and north of this, where the river margins are flat and wide, the riparian vegetation is luxuriant. From the A41 south the Colne is a rather energetic river constantly eroding the banks and exposing the Salix and Fraxinus roots and so leaving a constant supply of fallen wood which is, except in the vicinity of public footpaths, left to decay. Across the river from the reedbeds there are extensive and busy allotments. Pictures supplied by Conall Murray (Junior member) |
