Samples were sorted in the laboratory,one quarter of each.sample had all invertebrates removed,counted and identified to the lowest taxonomic levels, dependingon the taxon and its life stage. The remainder of the sample wasexamined for taxa unrecorded in the fraction counted and anyoccurring were incorpoated with the preserved material. (Datasheets indicate the multiplication factor ("mf") -X4 or XI).Taxa remaining for species determination are -Oligochaeta, Corixidae, Trichoptera (some) and Chironomidae.A few identifications await confirmation -e.g. some Caenis spp.This information will follow in July, it is unlikely to alterthe number of families recorded at each site from the "Spring"data.There are currently no noteworthy species that are glaringlyobvious, the upstream site appears less species-rich. Anotherinitial reaction was the dearth of oligochaetes (particuarlyNaididae) and mollusca (appart from Sphaeriidae). As alreadystated, some fauna associated with fast water and clean gravelwere not anticipated to occur at the chosen sites. It will beinteresting to see the RIVPACS predictions, which will take intoaccount the substrate composition..o. • . .tSAMPLEAREAFORMI.1I.1I _WA/RPB:	I 41-rficlt- rgeeRfpirreg eCOLOIteRIVER:- ...AA 6vel<SITE:	04/Z7-12r4 5-274C:€4f SCR:	Sy *384/8RECORDER(S):	 -actss L-e440/, ciPh4p_aDATE:	- •9;SAMPLETIME (MINS):	3•10/3SAMPLINGMETHOD:-.••e'en> (DIMENSIONSOF SAMPLINGDEVICE:-.22.4 2744.9eitr`1247/3"V-4012MESHSIZEOF NET*	 91014"-iWA/RPBSAMPLENUMBER(IFANY): --IS SAMPLINGIN PROPORTIONTOOCCURRENCEOF HABITATS:- YES NOIF NO GIVEDETAILS:-SUBSTRATUMIN SAMPLEAREAGIVEDETAILSFORTHEFULLWIDTHOF RIVERAT THESAMPLINGAREAIN COLUMNA INDICATETHEDOMINANTPARTICLESIZEBY / ANDTHEPRESENCE.OF OTHERS1Y4.INCOLUMNB ATTEMPTROUGHESTIMATESOF % COVERFORTHE.FOURCATEGORIESLISTED.IF-WENTWORTH.ANALYSISIS UNDERTAKENACTUALPROPORTIONSMAYBE SUBSTITUTED.(INCLUDESUBSTRATAUNDERMACROPHYTESIN ESTIMATESOF % COVER)AROCKPAVEMENT>256mm BOULDERS'>64-256mm COBBLES0,1eartP.740-nkik>16-64ma PEBBLES 30 Ityr plea khitti>2-16mm.GRAVEL 1 3o of -114g- MEA .>0.0625-2mm SAND JO>0.004-0.0625mm SILTVS0.004no CLAYTOTAL 100%/IWATERWIDTHIN SAMPLEAREA'DEPTHIN SAMPLEAREA(cm)AT 1 41 1ESTIMATEDSURFACEVELOCITYINMAINFLOWCHANNELcm sec"/3 m65 WIDTHCATEOORY1S101CATEGORY2>10- 251ICATEGORY3>25-5iCATEGORY4>50-104CATEGORY5>100SUMMARYWIDTH : 13MEANDEPTHVELOCITY'CATEGORY:2_BOULDERS•COBBLESa 10PEBBLESGRAVELSAND /toSILTXA.)•CLAYTOTAL 100ri1111111WINIIIIIIIIIINNIS1011•11O0111111111111•1111010111111•111/• •"EVER - SeFraW Stei-A1 6 y.-salpety-aenksEX20tipws!EA>Enat /II 644:1W®Fiat113/ergtde- eni - feeloval bgairne t(56nE Wer Auct.wMEgg - Ri c.t4or tactn-b itif.At,Cui .%.).041.3KmSKETCHOF SAMPLEAREAfleaRat-tr_tatagisaAkW44VaXAgo EP,IIreff' 910665;:)., 0so itfarr)WATERCLARITY:-WATERCOLOUR:-CLEARANDBRIGHTraCLOUDY 1--1 TURBIDIMOMACROPHYTES(INCLUDINGMOSSESANDLARGEALGAE)IN SAMPLE/SURVEYAREA.IDENTIFYTO SPECIESIF POSSIBLE.LISTIN ORDEROF ABUNDANCE.TICKSPECIESSAMPLEDFORINVERTEBRATES,MACROPHYTESIN SAMPLEAREA EXTRASPECIESIN SURVEYAREAkw/end& (ks•Ja -ME SAM.JaiS An Mt/At/LOS se. ke,..entAii,atom Riort.ii4ter14)-CE-9, Moll(C4qe4‹ - lcCktu-re.crIE Pukirsoag‘snwertan s--r a 4 1-04 Ckale-IN cct$Scr-c--4)sitthrte4aaflriarCOVER%:- ALGAE JO HOSS(o-o5,4.--C)DETRITUS(ROTTINGVEGETABLEMATTER,LEAVES):-HIGHERPLANTSPRESENTVATOTALABSENT1SADDITIONALINFORMATION(INCLUDINGCHANGESIN SAMPLEAREASINCELASTVISIT)Cpin 4=771W N )6cahlAat risi0 4 .
