Mae pori cadwraeth yn cael ei ddefnyddio ar nifer o wahanol diroedd, er engraifft coetir, prysgwydd, tiroedd gwlyb a glaswelltir. Mae da byw wedi llunio ein tirwedd ers cenedlaethau bellach, ac dyma\u2019r ffordd fywaf effeithiol a chynaliadwy o reoli ein cynefinoedd. Mae\u2019n bwysig bod y math cywir o anifeiliaid yn cael eu ddefnyddio ar y tiroedd hyn, yn gyffredinol bydd gwartheg, defaid a merlod yn cael eu defnyddio. Fel rheol byddant yn frid brodorol wedi cael eu magu i fod yn galed i fyw ar diroedd uwch ble mae lefel y glaswellt o ansawdd is o gymharu a diroedd isel. Byddant yn bwyta y rhywogaethau o blanhigion amlycaf, mae hyn yn caniatau cyfleoedd i amrywiaeth eang o rywogaethau eraill i gael sefydlu.<\/p>\n\n\n\n

Drwy ddefnyddio gwartheg a merlod mae\u2019n achosi aflonyddwch tir oherwydd eu pwysau, mae hyn yn darparu cynefinoedd ar gyfer ymlusgiaid ac infertebratau yn y pridd, maen\u2019t hefyd yn creu lleoliadau i\u2019r planhigion newydd ffynnu. Nid bwyta yn unig mae\u2019r anifeiliaid hyn yn gwneud ond hefyd maen\u2019t yn creu carthion!<\/p>\n\n\n\n

Oeddech chi\u2019n gwybod<\/h3>\n\n\n\n

Mae tros 250 o rywogaethau o bryfed yn bodoli ar un achos o dail gwartheg mae hyn yn darparu ffynhonnell hanfodol o fwyd i adar.<\/p>\n<\/blockquote>\n\n\n\n

Un safle sydd yn rhan or prosiect yw cae yng nhoed Nercwys, mae\u2019n weirglodd blodau gwyllt, mae defnyddio defaid i bori yma yn anghenrheidiol. Mae\u2019r cae yn cael ei dori ar gyfer gwair yn hwyrach ymlaen yn y flwyddyn wedi i\u2019r blodau gwyllt ar gweiriach ddod i had. Wedi i\u2019r gwair gael eu glurio bydd defaid yn cael eu rhoid yno, er mwyn pori y glaswelltir lawr yn barod i rywogaethau blodau yn y gwanwyn. Ni fydd y defaid yn pori yno trwyr gaeaf er mwyn osgoi unrhyw ddifrod ir tir.<\/p>\n\n\n\n

\"Cutting<\/figure>\n\n\n\n

Mae defaid yn borwyr detholus, maen\u2019t yn gallu bwyta llysdyfiant yn agos iawn ir ddaear. Ar hyn o bryd mae yna ddefaid mynydd Cymreig yn pori ar rhai or safloeodd y prosiect. Bridiau eraill sy\u2019n cael eu defnyddio yw defaid Jacob ac Hebridean, mae\u2019r ddau frid yma yn fridiau brodorol, caled bydd eu cyrn yn help iddyn nhw symud drwy mieri a rhedyn.<\/p>\n\n\n\n

Mae gwartheg yn pori glaswelltiroedd hir i greu safleoedd moel a manau agored. Mae\u2019r glaswelltir hwn yn darparu tir agored i adar hirgoes fwydo. Yn wahanol i ddefaid, mae gwartheg yn defnyddio eu tafodau er mwyn tynnu llysdyfiant allan or ddaear. Byddant yn bwyta llwyni ac eithin llymach yn ogystal a glaswellt. Ar hyn o bryd mae gwartheg Belted Galloways ar rhai o safleoedd y project, mae\u2019r brid hwn o wartheg yn cael eu defnyddio yn amal ar gyfer pori cadwraeth ar draws y wlad. Maen\u2019t yn frid eithaf bychan ac felly yn lleihau y difrod ar y ddaear.<\/p>\n\n\n\n

\"Brown<\/figure>\n\n\n\n

Y merlod sy\u2019n cael eu defnyddio ar gyfer pori cadwriaeth yn y prosiect hwn yw merlod y Carneddau. Maen\u2019t ychydig yn llai na\u2019r ferlen fynydd gymreig adran A, mae ganddyn\u2019t gorff bach cadarn a chlustiau bach. Mae merlod y Carneddau wedi arfer byw allan ar diroedd uchel dros 3,000 o droedfeddi gyda chlogwyni, llethrau creigiog a llynoedd. Felly maen\u2019t yn frid caled iawn. Maen\u2019t yn bwyta rhuthur meddal, Molina, eithin a glaswelltau mynydd. Drwy bori y tir maen\u2019t yn cadw tyfiant rhedyn ac eithin o dan reolaeth, mae hyn yn rhoi cyfloeodd i blanhigion a rhywogaethau eraill dyfu. Mae merlod hefyd yn pori yn agos ir ddaear ac yn creu gwardrobau lle na fyddant yn pori. Mae hyn yn creu amrywiaeth strwythurol ofewn y glaswelltir.<\/p>\n\n\n\n

Mae bridiau brodorol a phrin yn cael llai o broblemau iechyd o\u2019u cymharu a bridiau masnachol felly, tra\u2019n rheoli cadwraeth, mae\u2019n fonws mawr cael anifeiliaid sydd a llai o waith cynal a chadw arnynt.<\/p>\n\n\n\n
