Working for the Wealth of Wildlife II - Gweithio dros Gyfoeth Byd Natur II

GERDDI Mae gerddi (a lotments) yn amrywio llawer mewn maint a gwerth i fywyd gwyllt, ac yn gynefin lle gall llawer o bobl ddod i gyswllt uniongyrchol â bywyd gwyllt, a hefyd helpu yn uniongyrchol. Maen nhw werth eu hyrwyddo am y rheswm yma yn unig, ac weithiau yn cynnal cyfoeth o fywyd gwyllt o fewn ardaloedd cymharol fychain. Maen nhw’n cynnwys ardaloedd gyda nodweddion o gynefinoedd eraill (dolydd, coetiroedd, rhostir) ac yn helpu i gynnal llawer o blanhygion gwyllt, adar, amffibiaid a rhai mamaliaid bychain. Maent yn goridorau a cherrig rhyd rhwng un cynefin a’r llall. Arwynebedd/ safleoedd: Fe’u ceir, yn amlwg, mewn ardaloedd gwledig a threfol. Cyflwr: O safbwynt bywyd gwyllt, mae hyn yn amrywio yn fawr - gall gerddi ‘taclus’ a ‘bler’ fod yn dda neu yn wael ar gyfer bywyd gwyllt - mae hyn yn dibynnu ar reolaeth a ffactorau eraill. Ffactorau sy’n achosi Dirywiad/ Materion: - Tueddiad i roi wyneb caled ar erddi ffrynt, ar gyfer parcio, ac i leihau ar dorri gwair. - Tueddiad at goed bach nad yndynt yn frodorol, mannau gyda slabiau neu laswellt, a llai o fannau gyda ffrwythau a llysiau i’r teulu. - yn gysylltiedig a’r pwynt uchod, mae llai o domenni compost yn golygu llai o gynefin a chysgod i rywogaethau neilltuol. - Llawer o goed bach anfrodorol yn cael eu mewnforio a’u plannu heddiw (cyfleon wedi’u colli i blannu rhai brodorol felly). - Mae rhai rhywogaethau a gyflwynwyd trwy erddi wedi achosi problemau (fel Japanese knotweed). - Tueddiad i adael gerddi bychain iawn, heb lawer o botensial i fywyd gwyllt, wrth godi rhai tai newydd. - Cathod yn dal adar a rhywogaethau eraill (gan gynnwys y wiwer goch). Camau Presennol: (Yn ol dewis gerddwyr) # Gwneud a chynnal llynnoedd bychain ar gyfer bywyd gwyllt. # Cyflenwi blychau nythu i adar, byrddau

GARDENS Ranging greatly in size and in wildlife value, gardens (and allotments) are a habitat where many people can come into direct contact with wildlife and also help directly. Worth promoting for this reason alone, they in some cases support significant concentrations of wildlife within relatively small areas. They can include areas with features from other habitats (meadow, woodland, heathland) and can help support many wild plants and birds, amphibians and some mammals. They can act as corridors and stepping stones between other habitat areas. Area/ sites: Obviously found in both rural and urban areas. Condition: From a wildlife point of view, this varies greatly - both ‘neat’ and ‘untidy’ gardens may or may not be good for wildlife, depending on management and other factors. Factors causing Decline/ Issues: - Trend towards hard-surfacing on front gardens, for parking and to lessen mowing. - Tendency for more ornamental non-native shrubs, areas of slabs or grass, and less areas of fruit and veg. for family food. - Associated with the last point above, less compost heaps mean less habitat and shelter for certain species. - Many shrubs and flowers planted today are imported and non-native (so, lost opportunities for native plantings). - Some non-native species introduced through gardens have caused problems (such as Japanese knotweed) - A tendency for some new houses to have very small gardens with limited potential for wildlife - Cat predation on birds and other species (including red squirrel). Current Action: (By gardeners’ choice) # Making and maintaining garden wildlife ponds # Providing bird nest boxes, feeding tables

CORSLEOEDD Mannau gwlyb lle mae'r gorsen gyffredin yn amlycach na'r un planhigyn arall. Mewn corsleoedd mae tabl y dwr un ai ar lefel y tir neu uwchlaw am y rhan fwyaf o'r flwyddyn. Oherwydd y cysgod y tu mewn i'r gwely mae ynddo gynefin gwerthfawr i sawl rhywogaeth, rhai ohonynt yn arbenigwyr i welyau cyrs, megis deryn y bwn. Mae gwelyau cyrs yn bwysig yn nhermau cymeriad lleol. Arwynebedd/ safleoedd: 103 ha ar 39 o safleoedd. Ym 1992, roedd 62% o'r safleoedd yn llai na 2 ha, 23% y tu mewn i'r maint 2ha - 5 ha, roedd 15% o'r gwelyau cyrs yn fwy na 5 ha (Moralee a Hughes, 1992). O gymharu arolwg 1986 ag un 1992 gwelwyd bod 20% o'r safleoedd wedi gostwng yn sylweddol o ran maint. Mae 18% o'r safleoedd rhyw fymryn yn llai, ond nid oedd yr un safle wedi tyfu. Cyflwr: Wedi eu cynnwys mewn SDdGA yn Llyn Garreglwyd, Gwely Cyrs Rhoscolyn, Llyn Maelog, Llynnau y Fali, Cors Ddyga, Llyn Bodgylched. Mae cyrs yn tyfu ar safleoedd gwlybion eraill gan gynnwys GNC y Gors Goch, Cors Erddreiniog a Chors Bodeilio; at y rhain mae safleoedd heb eu dynodi megis hwnnw yn Llanlleiana. Ffactorau sy'n achosi Dirywiad/ Materion: - Draenio - Olyniaeth naturiol - Dirywio - Mewnlenwi - Pori, o bosib, gan stoc Camau Presennol: # Ar warchodfa y GFGA yng Nghors Ddyga ychwanegir at y cyrs. # Rheolaeth yn Llyn Garreglwyd, Llynnau y Fali a Rhoscolyn, Llyn Traffwll a Chors Crugyll yn gwella cyflwr y corsleoedd. # Sefydlu gwelyau cyrs i bwrpas trin dyfroedd, o bosib, i Langefni a’r Gaerwen (eisoes ym Mrynsiencyn). # Mae Strategaeth Gwlyptiroedd Môn (SGM) a Gwlyptiroedd i Gymru wedi cyd-drefnu’r gwaith gwella gwlyptiroedd.

REEDBEDS Wet places where the dominant plant is common reed. Reedbeds often have the water table at or above the ground level for most of the year. The sheltered conditions within the reedbeds provide many species with valuable habitat, some of which are reedbed specialists, such as the bittern. Reedbeds are important in terms of local character. Area/ sites: 103 ha made up of 39 sites. In 1992, 62% of sites were less than 2 ha, 23% of sites were within the range of 2 - 5 ha, 15% of reedbeds were larger than 5 ha. (Moralee and Hughes, 1992). Comparison of 1986 and 1992 surveys showed that 20% of sites had decreased markedly in size. 18% of sites had become slightly smaller, but no sites had become larger. Condition: Included within SSSI at Llyn Garregllwyd, Rhoscolyn Reedbed, Llyn Maelog, Llynnau y Fali, Malltraeth Marsh, Llyn Bodgylched. Reed also present on several other wetland sites including Cors Goch, Cors Erddreiniog and Cors Bodeilio NNRs; there are also some unnotified sites such as Llanlleiana. Factors causing Decline/ Issues: - Drainage - Natural succession - Degradation - Infill - Possible grazing by livestock Current Action: # RSPB Malltraeth Marsh reserve increasing reedbed cover. # Management at Llyn Garreglwyd, Llynnau y Fali, Rhoscolyn, Llyn Traffwll and Plas Bog is improving reedbed condition. # Possible establishment of reedbeds as water treatment method for Llangefni and Gaerwen, (already in Brynsiencyn). # Anglesey Wetland Strategy (AWS) and Wetlands for Wales have coordinated wetland enhancement.

FFEN Llecynnau gwlyb ble mae'r planhigion yn tyfu mewn mawn. Yn gyffredinol mae ynddynt ddwr yn rhedeg dan yr wyneb sy’n gyfoethog o galch - gyda pH canolig i uchel - yn wahanol i gorsydd ble mae'r dwr yn asidig neu gorsydd ac ynddynt ddwr glaw yn unig. Gall y twf fod yn amrywiol iawn, gan gynnal llawer o rywogaethau o blanhigion sy’n blodeuo, a phryfed. Mae gan Ynys Môn nifer o enghreifftiau da iawn o ffeniau. Arwynebedd/ safleoedd: (Pridd basn basaidd iawn + pridd dyffryn basaidd iawn + tir gwlyb basaidd iawn + swamp = 470 ha) yn enwedig Cors Erddreiniog, Cors Bodeilio, Cors Goch a Chors y Farl (safle RAMSAR darniog). Hefyd mae rhai ffeniau bychain eraill yn ardaloedd calchog y dwyrain gyda darnau bychain o bocedi gwlybion basn yn y gogledd. Cyflwr: Difrodwyd llawer iawn o ffeniau oherwydd draenio i bwrpas amaethyddol, a hefyd oherwydd cefnu ar ddulliau traddodiadol o bori. Mae Ewtroffeiddio (codi lefelau'r maeth) yn broblem oherwydd dwr amaethyddol sy'n rhedeg i ddalgylch y safleoedd, a hefyd o lygredd yn yr atmosffer. Mae'r safleoedd mwyaf i gyd yn SDdGA, gan gynnwys safleoedd SAC ac RAMSAR. Mae rhai llecynnau bychain ar eu pennau eu hunain y tu allan i ffiniau statudol. Ffactorau'n achosi Dirywiad/ pynciau: - Draenio - Codi lefelau'r maeth, e.e. o ledaenu gwastraff amaeth-ddiwydiannol (fel offal) ar y tir. - Gadawiad pori a thorri mawn mewn dulliau traddodiadol Camau Presennol: # Rheolaeth o SDdGA gan CCGC ac YBNGC. # Rheoli prysgwydd a phori ar warchodfeydd. # Mae strategaeth Gwlyptiroedd Ynys Môn wedi cyd-gysylltu gwaith gwella tiroedd o'r fath.

FENS Wet boggy areas where the vegetation grows in peat. They are generally irrigated with lime-rich ground water - of moderate to high pH, in contrast to bogs which are irrigated either with acid groundwaters or only rainwater. Vegetation can be very diverse, supporting many species of flowering plants and insects. Anglesey has some very good examples of fens. Area/ sites: (Base-rich basin mire + base-rich valley mire + base rich flush + swamp = 470 ha) notably Cors Erddreiniog Cors Goch, Cors Bodeilio and Cors y Farl (composite RAMSAR site). Other small fens are associated with the limestone areas of the east and with small basin mires in the north. Condition: Many fens have been damaged by drainage for agricultural improvement, and also by abandonment of traditional grazing activity. Eutrophication (nutrient enrichment) is a problem due to agricultural runoff within the catchment of the sites, and also from atmospheric pollution. All the larger sites are SSSIs, including SAC and RAMSAR sites. Some small patches lie isolated outside statutory boundaries. Factors causing Decline/ issues: - Drainage - Nutrient enrichment, e.g. from spreading of agri-industrial waste (such as offal) on land. - Abandonment of traditional grazing and peat cutting. Current Action: # CCW and NWWT management of SSSIs. # Scrub and grazing management on reserves # Anglesey Wetland Strategy has coordinated wetland enhancement.

LAKES Areas of open water (> 1 ha). Anglesey has many lakes, and is an important area for breeding wildfowl. Lakes also support a good range of aquatic plants, insects, and other species. Area/ sites: Sites include Llyn Maelog (36 ha), Llyn Llywenan (41.5 ha), Llyn Traffwll (44.8 ha), Llyn Alaw (360 ha). Llyn Penrhyn, Llyn Dinam and Llyn Traffwll are RSPB reserves. Llyn Rhos du, Llyn Cadarn and Llyn yr Wyth Eidion are within National Nature Reserves (NNRs). No total area figure is available. Condition: Various, but many are declining due to widespread over-enrichment with nutrients. Most of larger lakes are SSSI. Factors causing Decline/ Issues: - Eutrophication (nutrient enrichment) due to catchment management. - Exotic fish introductions. - Recreation (e.g. windsurfing, fishing). - Artificially lowered water level. (eg Llyn Hendref). - Natural succession, leading to infilling. Current Action: # Phosphate stripping at Llyn Penrhyn. # CCW research at Llyn Penrhyn. # Anglesey Wetland Strategy monitoring programme.

FIELD EDGES Basically grassland edges or strips of land lying between crops and the field boundary. The margin habitat can attract animals such as the brown hare, corncrake, barn owl and the grey partridge. It is also important for other birds, small mammals and some rare arable flowers. Area/ Sites: No information specific to Anglesey. Condition: Large-scale decline on Anglesey due to changes in farming practice - decline of mixed farming/ arable acreage. Factors causing Decline/ issues: - Changes in farming economy; Cereal losses in Anglesey can be seen as part of overall retreat of cereal growing in the west and north of Britain. - Overgrazing of hedge bottoms. - Spread of intensive improved grazing. Where cereals still grown:- - Use of herbicides and pesticides. - Shift to winter cropping with loss of winter stubbles. - Lessening of rotation of cereals with grass leys and fallows. Current Action: # ESA Scheme payments for unsprayed cereal crops (agreement renewal only). # Provision of expert advice for organic conversion and Tir Gofal Scheme possibilities.

SCRUB Stands of native shrubs; most of the dense scrub areas on Anglesey are gorse. Scrub can be a successional stage before pioneer woodland, as well as forming a buffer zone around/ between habitat areas (or linking such areas), where it can be important for a number of species. Area/ sites: 652 ha. Gorse in many areas. Hazel scrub found in limestone areas of east, while willow scrub may occur in ungrazed drained wetland areas like Llyn Padrig and Llyn Hendref. Condition: Variable; not known in detail. Often associated with other habitats such as woodland, heath and wetlands. Valued (in moderation) e.g. for wildlife shelter and food plants, in association with other habitats. Factors causing Decline/ Issues: - Spreading in some sites; conflict with heathland, grassland and wetland management, where scrub is expanding at the expense of these habitats. - Loss at other sites; removal to increase farm forage area (IACS). Current Action: # Removal of scrub from sensitive areas of, for example, nature reserves. Overall Objectives and Targets To take account of this habitat for biodiversity planning, for its association with other habitats and species.

PLANHIGFEYDD Coed a choedwig a blannwyd yn neilltuol gan ddyn. Wedi tueddu i fod yn gonwyddau ers tua 1920, ond planir coed llydanddail hefyd. Mae planhigfeydd Ynys Môn tua 1450 ha, yn fwy na chyfanswm arwynebedd y coedydd lled naturiol. Planhigfeydd conwydd yw'r rhan fwyaf, gyda phinwydden Corsica yn bennaf, fel y ceir yn SDdGA Coedwig Niwbwrch. Mae potensial i gael effeithiau buddiol ar amryw rywogaethau ac amrywio amaethyddiaeth, pe plannid coedlannau collddail ar gyfer tanwydd ac fel adnodd crai. Arwynebedd/ safleoedd: Coedwig Niwbwrch (700ha), Coedwig Pentraeth (245 ha) ac o gwmpas Llyn Cefni (78 ha), Coed Nant/ Coed Cadw (11 ha) (stondynau mewn mannau eraill). Cyflwr:. Tyfiant ac aeddfedrwydd sy'n amrywiol. Mae planhigfa pinwydd yn ffurfio cynefin pwysig i'r wiwer goch (Pentraeth), croesbig, tylluan frech, cyffylog, cnocell y coed, bwncath, ystlumod brown, clustiog a lleiaf (Niwbwrch a Phentraeth). Materion - Gwrthdaro gyda'r hen gynefinoedd (twyni tywod a rhostir) a gwerth bywyd gwyllt y rheini yn uwch. - Yn y gorffenol, mae ffactorau masnachol/ prisau’r farchnad pren wedi dylanwadu rheolaeth coedwigoedd trwy rheoli pryd i deneuo a phyd i dorri coed; hefyd gallant rhwystro ac atal gwaith rheoli coed aeddfed.

PLANTATIONS Wood and forest specifically planted by man. Tend to have been conifers since about 1920, but can include broadleaf. Anglesey’s roughly 1450 ha of plantations cover a greater area than semi-natural woodlands. Most is conifer plantation, with Corsican pine dominating, as at Newborough forest SSSI. The planting of broadleaf coppice woods for fuel and as a raw material on farmland holds a possibility of benefiting various species, whilst helping agricultural diversification. Area/ sites: Newborough Forest (700 ha), Pentraeth Forest (245 ha), around Llyn Cefni (78 ha), Coed Nant/ Coed Cadw (11 ha) (smaller stands elsewhere). Condition: Varying stages of growth and maturity. Pine plantation forms important habitat for red squirrel (Pentraeth), crossbill, tawny owl, buzzard, woodcock, woodpecker, brown, long-eared and pipistrelle bats (Newbro’ and Pentraeth). Issues - Conflict with already existing habitats (sand dunes and heathland) of greater wildlife value. - Commercial factors/ timber market prices have in the past influenced forest management by determining when timber is thinned and felled etc; can also deter management for mature timber. Current Action: # Forest design plans (FE) take account of forest dependent species such as red squirrel and siskin. Overall Objectives and Targets That plantation forestry is operated to the mutual benefit of biodiversity. Proposed Action: Management and Protection # Use plantation to boost woodland cover, thus supporting Anglesey Woodland Strategy and Wales Woodland Strategy.

LIMESTONE PAVEMENT Limestone pavements are a scarce and nonrenewable resource - Anglesey has few good examples. As well as their geological interest they are important for biodiversity and can support many plant species. Area/ sites: Plas Lligwy woods, Y Bonc Marianglas, Borth Wen Benllech, Bwrdd Arthur, Mariandyrys SSSI. Condition: Mostly wooded or small coastal exposures. Only small and relict pavements remain, although the abundance of water worn limestone in walls and buildings suggest it was once much more widespread.

SEAGRASS BEDS Formed by plants known as eelgrasses (Zostera spp.), which grow on mud and sand in shallow waters. Beds are important for their high productivity (important source of organic matter), their stabilising effect on sediments, and for the shelter and substrate they provide for many species. Also provide an important source of food for wildfowl. Area/ sites: Beddmararch-Cymyran SSSI (including the Inland Sea). Inland Sea records of 1978: from the most sheltered areas, and to the south and east of Ynys Benlas on west side. Status unknown today. Possibly off southwest Anglesey. Condition: Considered to be nationally scarce with a patchy distribution. Completion of an intertidal Phase 1 survey in 2003 will allow this to assessed. Factors causing Decline/ issues: - Have suffered apparently natural mortality due to fungal wasting disease in past. - Oil pollution and oil treatment chemicals - High levels of nitrates, leading to smothering by algae. - Physical disturbance by e.g. bait digging, anchoring. - Changes in sediment, dredging and coastal protection. - Heavy metal uptake may affect viability. - Herbicides and antifoulants have adverse effects.

Mae arni eisiau ardaloedd gyda llystyfiant tal yn y gwanwyn, ac yn yr haf bydd yn symud un ai i gaeau gwair neu i silwair a dorrir yn hwyr ar gyfer bridio/ nythu. Fe'i diogelir dan Restr 1 Deddf Bywyd Gwyllt a'r Cefn Gwlad, ond, yn drist, mae mewn peryg o ddiflannu yn fyd-eang. Statws Presennol: Fe'i disgriwyd fel prin ac achlysurol yn Jones (1990). Cofnidion bridio achlysurol, G Cymru, gan gynnwys Ynys Mon. Bu gynt yn gyffredin ar yr ynys. Materion: - Dechreuodd ddirywio yn sgil mecaneiddio gwaith torri cnydau. - Newid o gynhaeaf gwair i silwair, sy wedi arwain at dorri llawer ynghynt, sy'n anffafriol ar gyfer bridio/ nythu. - Colli ymylon o gwmpas caeau âr. - Lefelau stocio uchel.

CORNCRAKE Crex crex Formerly common in many areas of the British Isles and Europe, this species was well known for its distinctive 'crek crek' call. It has undergone a steady decline in recent times, due to various changes in agriculture. Needs areas with tall vegetation in spring, and in summer moves to late-cut hay or silage meadows for breeding/ nesting. Protected under Schedule 1 of Wildlife and Countryside Act, but is sadly considered to be in danger of worldwide extinction. Current Status: Described as a 'rare and occasional' visitor in Jones (1990). Occasional breeding records in N Wales, including Anglesey. Formerly widespread on the island. Issues: - Began decline with mechanisation of cutting. - Change from hay making to silage has lead to much earlier mowing, unfavourable for breeding/ nesting. - Loss of arable margins. - High stocking rates. Current Action: # RSPB monitoring for presence and checking reports of sightings. # Species provides a case study for biodiversity effects of agricultural change. Overall Objectives and Targets To establish feasibility of long-term reestablishment in light of agricultural changes. To promote conditions that could lead towards reestablishment of the species (breeding). Proposed Action: Management and Protection # Promote corncrake friendly practice through Tir Gofal scheme.

SKYLARK Alauda arvensis This well known ground nesting song bird has declined in lowland areas in recent decades. This is thought to have been brought about through wide-ranging agricultural changes. Serious declines in common species are seen as indicators of great environmental change. Protected under Wildlife and Countryside Act. Current Status: Declining. Still present on areas such as dunes and commons. Issues: - Loss of food supply (insects) due to conversion of hay meadows to improved grass for silage. - Early harvest/ cut destroys nests and exposes birds to predators. - Loss of arable land to intensive grazing. Current Action: # BTO Breeding Bird Survey. # Management of dunes and commons. Overall Objectives and Targets To ensure the survival of the species throughout the island. Proposed Action: Management and Protection # Promote skylark friendly practice through Tir Gofal agri-environment scheme.

GREY PARTRIDGE Perdix perdix Numbers of breeding pairs of this gamebird halved between 1969 and 1991 in Britain, directly as a result of agricultural changes. Current Status: Not known in Anglesey. Roberts noted that 'Grey Partridges maintain their numbers and are recorded all over the island' (Jones ed. 1990). Issues: - Change from hay making to silage. Earlier harvest dates lead to nest destruction. - Grass cutting pattern can trap birds in middle of field. - Loss of arable margins and decline in hedgerows as insect food sources. - Shift from mixed farming to intensive sheep grazing. - Use of pesticides. Current Action: # Likely to have benefited from ESA scheme agreements (only small uptake of Tir Gofal at time of writing).

Statws Presennol: Recordiwyd wrth yml Carreglefn, mewn gwlyptir. Materion - Diffyg rheolaeth, gan arwain at sefydliad llystyfiant trwchus. - Mae gostwng y tabl dwr yn fygythiad posib. Camau Presennol: # CCGC yn gwneud asesiad. Amcanion Cyffredinol a Thargedau Egluro statws y rhywogaeth ym Môn, a diogelu safleoedd. Camau Arfaethedig: Gobeithir bydd yr asesiad yn arwain at ganllawiau ar gyfer gweithredu. Rheolaeth ac Amddiffyniad # Rhestru o bosib, rhagor o safleoedd fel SDdGA. CCGC # Gorfodaeth cyfraith addas, a gweithredu pe bai angen. HGC Cynghori # Rhoddi cyngor ar gyfraith cadwraeth.

Rare in the UK, and mainly an upland species, it is sometimes found in lowland fen. Included in Wildlife and Countryside Act (Schedule 8). Current Status: Recorded near Carreglefn in wetland. Issues - Lack of management leading to establishment of dense vegetation. - Lowering of water table is at least a potential issue. Current Action: # Assessment underway by CCW. Overall Objectives and Targets To clarify species' status in Anglesey and safeguard sites. Proposed Action: Assessment will hopefully lead to guidelines for future action. Management and Protection # Possible listing of sites as SSSI where not already so designated. CCW # Appropriate law enforcement and action, if needed. NWP Advisory # Provision of conservation law advice. NWP Research/ Monitoring Implementation: Lead: CCW Key players: CCW Main Links/ Common Interest with Other HAPs and SAPs: Fen
