Details

We met at the lay-by next to Duck Holt on the A19 – SE 561095 and walked the short distance north to the entrance of the Croft Farm site. The whole area was once Ouston Common with a drain running across the site (see Owston Enclosure Award – 1762), but during the 20th century it was covered by a slag heap from Bullcroft Colliery which closed during the 1960s. It has never been landscaped but left to regenerate naturally, a very unusual circumstance! Unfortunately, the drain has been blocked by subsiding slag and plans are afoot for the diversion of the drain which may well impact on a neighbouring wet meadow with a large bed of Phragmites reed.

The Local Authority turned down a planning application to excavate the tip, providing a large hole for landfill with subsequent creation of ‘a public amenity site’. The developers have appealed against the decision. There is a great opposition to the development locally, with an active Action Group.

Our main recording area lies within the 1km square SE 5509 except for the open patch immediately adjacent to the entrance off the A19 which is in SE 5609. This access road has a limestone base. There was evidence of the tipping of garden waste with Daffodils and Aquilegia present.

The day was sunny and warm as it had been for most of the previous week, and the ground was dry and cracked. However, there was evidence of the recent wet conditions with signs of run-off and numerous small areas of Phragmites in the more open areas between the regenerating Birch.

We only came across one small area of open water, a puddle about 2ft x 4ft, supporting some aquatic fauna, including Pond Skaters, Water Boatmen, and small Water Beetles.

Gall list compiled by Tom Higginbottom

A small by interesting list of galls, perhaps not so surprising so early in the year.

The extensive Birch scrub did not [provide any galls, it might be worth another visit in late summer. Scrub Oak, more than likely Quercus robur, was difficult to find initially. All the Oaks which were discovered had significant numbers of Andricus fecundator, Andricus kollari and Andricus lignicola.

Many Oaks were not in leaf, on the few which were, the sexual generation of Neuroterus quercusbaccarum was found on newly formed leaves.

All the galls, apart from Neuroterus quercusbaccarum, were old galls.

The bud gall Andricus ambiguous and the series of small holes in a young twig, which indicates the presence of Andricus Quercusradicis, were interesting discoveries.
