Upton Warren Worcs BRC Survey Day

Saturday 31st July 1999 was the day selected to undertake a survey of wildlife other than birds at Upon Warren. The area is an important wetland and up-welling brine has led to the fevelopment of important inland salt marsh at the Flash Pools. The saltmarsh plants are well-known but we have little knowledge of other taxa. Our plan was, in retospect, over-ambitious. We aimed to cover the Flash Pools, the County Council Educational Reserve by the sailing lake, and the Moors Pool area. In the event we only managed partial coverage of the first two, in part because it was a very hot, dry day. Nevertheless. a good series of records were obtained which give indication of what needs tobe done in the future. As far as insects are concerned many specimens (especially beetles) remain to be identified and results from that work will be published later. A lot of recording still needs to be done at this important site.

This is most probably the common Chyromya flava, described in Colyer and Hammond (1951 ) but I do not have the literature to confirm it. The only key I can trace is a German one in Die Fliegen der Palaerktischen Region. Name amended from Chryomyia reference Kloet and Hincks.

Large numbers of ephydrids were present in the sedges and on the surface of the mud. I have no literature for most of them but the genera Notiphila, Ephydra, Scatella and Psilopa appeared to be present.

Here is a list of the bryophytes I collected at Upton Warren on July 31st. Conditions were too dry to be conducive for finding bryophytes, and I am sure that this list could be doubled or trebled by a visit in winter. None of the species in the list are in any way unusual; most could be found in a municipal park, and I do not think that Upton Warren is likely to have unusual bryophytes unless some can be relocated in salty conditions. Unfortunately, I failed to find a single moss or liverwort where the Puccinellia or Spergularia grew.

A survey was undertaken of the wayside and hedgerow trees around the sailing club lake and flashpools nature reserve and also on the thinly vegetated soils behind the petrol station/plant hire yard.

The survey at Upton Warren provided a corticolous flora that is typical for the area, together with an interesting terricolous site. Lignum (mainly fence posts) together with concrete walls and posts provided further substrates. Saxicolous habitat was however somewhat limited on the site. The churchyard was therefore visited to provide a list from a stable saxicolous habitat.

A total of 57 species were recorded, 34 on the Upton Warren site and 32 in the churchyard. The latter was not very rich when compared with many other Worcestershire churchyards but is perhaps typical of the more polluted northern Worcestershire yards.

The 34 species on the Upton Warren site include 10 on the thinly vegetated soil and pebbles, 21 on bark and lignum and 3 restricted to concrete. The bark/lignum species are typical of acidified trees and lignum in polluted areas. P. caperata was recorded only once and is indicative of reducing sulphur dioxide levels. Further colonisation of this habitat can be expected.

The terricolous species included seven Cladonias, of which C. foliacea and C. rangiformis, together with Diploschistes muscorum and Peltigera rufescens are indicative of base rich soil. Other species such as Cladonia ciliata var tenuis and C. portentosa are normally found on acid substrates and are possibly growing raised above the soil. The community is dependent on sparse vegetation and may thus be temporary. i.e. the community might be lost if the vegetation sward was to thicken into a dense turf or scrub.

None of the species found on these sites are considered rare. Cladonia foliacea, C. ciliata var tenuis and Diploscistes muscorum may be considered local in Worcestershire but more data is required before this can be confirmed.

Flowering Plants

Bert Reid

The surrounds of the flash pools are one of the best inland salt marhes in Britain and the visit tumed up a good number of the special plants from here. Puccinellia distans (Reflexed Saltmarsh-grass) and Spergularia marina (Lesser Sea-spurry) fonned a narrow band on the otherwise bare mud around the pools. Just landward of these were good stands of Juncus compressus (Round-fruited Rush). A couple of specimens of the rush were taken to make sure that they were not Juncus gerardii (Saltmarsh Rush) which is thought extinct in Worcestershire but measunnent of seed size dashed any hopes in that direction. A puzzling plant in the saltmarsh area was an orache sirnilar to Atriplex prostrata but looking rather different to the normal ruderal form common in the county. Unfortunately the plant was too young to identify.

The tall marsh vegetation behind the saltmarsh area contained few surprises but we did find a small patch of Potentilla palustris (Marsh Cinquefoil) which is scarce in the county.
Schoenoplectus tabemaemontani (Grey Club-rush) was quite widespread.

The land within the educational centre was completely different. The most striking feature here was the presence of a number of non-native plants. Impatiens glandulifera (Indian Balsam) was common and Crassula helmsii (New Zealand Pigmyweed) dominated a couple of pools. The little Lemna minuta (Least Duckweed) covered the surface of some ponds and the international flavour was complete by a large plant of Lysichiton americanus (American Skunk-cabbage). Even the Ranunculus lingua (Greater Spearwort) is surely an introduction here.

Not all the plants in this area are introductions, however, and it was pleasing to find a good stand of Carex ovalis (Oval Sedge) in a dried up hollow accompanied by a mixed colony of Juncus acutiflorus (Sharp-flowered Rush) and J. articulatus (Jointed Rush). I failed to convince myself that any plants were the hybrid between the two rushes although some did look possible. By the brook we saw quite a lot of Dipsacus pilosus (Small Teasel).

Amphibians and Reptiles

from a report by Will Watson and a few other casual observations.

No reptiles or amphibians seen at the Flash Pools


A Slow-worm Anguis fragilis found under log piles in drier part of Education Reserves


Pool on Education Reserve at grid ref SO936673

83 Smooth Newts Triturus vulgaris
22 Great-crested Newts Triturus cristatus

were counted from netted sampling. Only about 20% of the edge of the site was covered by the survey The body of water is over 0.5 hectares and supports a very large Smooth Newt population. The Great-crested Newt population is "good" or "excellent" ("Excellent" is when over 100 are seen during the survey)

Random searches of litter beneath trees etc in other parts of the Education area revealed at least three first-year Common Frogs Rana temporaria, one Common Toad Bufo bufo, 23 adult and two juvenile Smooth Newts, and four adult Great-crested Newts

The Education Reserve is an important and valuable site for amphibians.
