| East Of England | Hertfordshire | Welwyn Hatfield | Broadleaved, mixed and yew woodland - lowland | Andrew Mills | 4 | 1004871 | 41.26 | 14 Apr 2004 | Unfavourable declining | Encroachment of invasive species, in particular rhododendron in the south west area near to Griffins Hole, is the main contributing factor to the decline in condition of this unit. Bracken has also taken over the heath feature, leaving very little grassland habitat in open areas of the unit. Two plants of creeping willow found beside path across open area. | Forestry and woodland management, Inappropriate scrub control, Undergrazing |
