Ag deireadh na hOighearaoise deireana\u00ed thart ar 10,000 bliain \u00f3 shin, cuireadh t\u00fas le cruth\u00fa m\u00f3na in \u00c9irinn.

D’fh\u00e1s planda\u00ed ar n\u00f3s giolcach feadh imeall na lochanna. De r\u00e9ir mar a fuair na planda\u00ed sin b\u00e1s, thosaigh siad ag lobhadh ag r\u00e1ta mall mar gheall ar an timpeallacht fhliuch. Tharla s\u00e9 seo go pr\u00edomha mar gheall ar easpa ocsaigine a chuir cosc ar dhianscaoileadh miocr\u00f3bach. Charn fu\u00edlleach na bplanda\u00ed ar ghrinneall an locha mar shraith m\u00f3na. Tugtar m\u00f3in eanaigh ar an m\u00f3in seo a thagann le ch\u00e9ile faoi bhun leibh\u00e9al an uisce. Le himeacht ama d’\u00e9irigh an tsraith m\u00f3na n\u00edos tibhe agus laghda\u00edodh limist\u00e9ar an uisce oscailte go m\u00f3r. Is screamhuisce an t-uisce a chuirtear isteach in eanach agus t\u00e1 s\u00e9 saibhir i mianra\u00ed. T\u00e1 roinnt eanach tar \u00e9is teacht chun cinn mar phortaigh ardaithe. Tarla\u00edonn an dul chun cinn seo thar na c\u00e9adta bliain de r\u00e9ir mar a iompa\u00edonn an mh\u00f3in agus an t-uisce \u00f3 dh\u00e1la\u00ed alcaileacha go d\u00e1la\u00ed aig\u00e9adacha. Meallann an t-athr\u00fa sna tosca aibitheacha seo pobal \u00e9ags\u00fail planda\u00ed agus ainmhithe. I gc\u00e1s gur d\u00e1la\u00ed a bhaineann le gn\u00e1th\u00f3g alcaileach is m\u00f3 at\u00e1 ann, is eanach \u00e9; i gc\u00e1s gur d\u00e1la\u00ed a bhaineann le gn\u00e1th\u00f3g aig\u00e9adach is m\u00f3 at\u00e1 ann, is portach ardaithe \u00e9.<\/p>\n
Nuair a thosaigh planda\u00ed ag lobhadh ag imeall locha agus nuair a bh\u00ed coinn\u00edollacha ceart le go bhf\u00e9adfadh eanach m\u00f3na tos\u00fa teacht le ch\u00e9ile, thosaigh na lochanna ag laghd\u00fa i m\u00e9id de r\u00e9ir a ch\u00e9ile go mall. Lean an t-eanach air ag f\u00e1s agus le himeacht ama thosaigh gn\u00e1th\u00f3g phortaigh ardaithe ag teacht le ch\u00e9ile. Is \u00e9 an t-aon uisce a shol\u00e1thra\u00edtear chuig portach ardaithe n\u00e1 uisce b\u00e1ist\u00ed at\u00e1 an-\u00edseal i gcothaithigh.<\/p>\n\n
Tosa\u00edonn an caonach m\u00f3na at\u00e1 oiri\u00fanaithe chun f\u00e1s i nd\u00e1la\u00ed \u00edseal cothaitheach agus aig\u00e9adacha a bheith ina phlanda ceannasach. Is \u00e9 an planda seo an \u2018t\u00f3g\u00e1la\u00ed portaigh\u2019. D\u00e9anann s\u00e9 an portach n\u00edos aig\u00e9ada\u00ed tr\u00ed mheicn\u00edocht chasta mhalartaithe agus crutha\u00edonn s\u00e9 patr\u00fan saini\u00fail tul\u00f3g agus log ar dhromchla beo an phortaigh. Is substaint cos\u00fail le hithir \u00ed an mh\u00f3in at\u00e1 d\u00e9anta as fu\u00edlleach lofa de phlanda\u00ed marbha at\u00e1 carntha os cionn a ch\u00e9ile in \u00e1iteanna b\u00e1ite leis na m\u00edlte bliain. Is \u00e9ard at\u00e1 ann n\u00e1 caonach m\u00f3na chomh maith le fr\u00e9amhacha, duilleoga, bl\u00e1thanna agus s\u00edolta fraoigh, f\u00e9ar agus c\u00edbleach.<\/p>\n\n
Thosaigh Portach Chl\u00f3irthigh ag teacht le ch\u00e9ile thart ar 8000 \u2013 10,000 bliain \u00f3 shin nuair a l\u00edonadh an loch le sraith f\u00e1sra marbh a chruthaigh m\u00f3in eanaigh. Tharla s\u00e9 sin ag an am c\u00e9anna is ar thosaigh portaigh ardaithe ag teacht le ch\u00e9ile in \u00c9irinn. T\u00e1 me\u00e1ndoimhneacht m\u00f3na de 9 go 12 mh\u00e9adar ag portaigh ardaithe. T\u00e1 Portach Chl\u00f3irthigh 10 m\u00e9adar ar doimhneacht anois. Braitheann sraith 30 ceintim\u00e9adar de chaonach m\u00f3na beo gn\u00edomhach, ar bharr na m\u00f3na marbh, ar uisce b\u00e1ist\u00ed nach bhfuil m\u00f3r\u00e1n cothaithigh ann. Titeann thart ar 850 millim\u00e9adar b\u00e1ist\u00ed gach bliain.<\/p>\n

Lasmuigh den cheantar L\u00e1r T\u00edre, tugtar bratphortach ar fhormh\u00f3r na dtailte portaigh in \u00c9irinn, go h\u00e1irithe san Iarthar. Tagann siad le ch\u00e9ile i gceantair ina bhfuil an me\u00e1nmh\u00e9id b\u00e1ist\u00ed a thiteann go bliant\u00fail os cionn 1,200mm agus ina dtiteann an bh\u00e1isteach 235 l\u00e1 ar a laghad gach bliain. Thosaigh Bratphortaigh ag teacht le ch\u00e9ile thart ar 4,000 \u2013 7,000 bliain \u00f3 shin; t\u00e1 siad i bhfad n\u00edos \u00f3ige n\u00e1 portaigh ardaithe.<\/p>\n\n
Mar gheall ar ghlanadh crann sna ceantair seo, chomh maith leis an mb\u00e1isteach mh\u00f3r, shil mianra\u00ed ar n\u00f3s iarainn s\u00edos go dt\u00ed na sraitheanna ithreach n\u00edos \u00edsle. Charn na mianra\u00ed chun sraith neamhscagach a chruth\u00fa, ar a dtugtar cruachiseal iarainn. Tharla talamh b\u00e1ite mar gheall air sin agus bh\u00ed s\u00e9 sin fabhrach don chruth\u00fa m\u00f3na.<\/p>\n\n
Is \u00e9 1.2 \u2013 3 mh\u00e9adar an me\u00e1ndoimhneacht mh\u00f3na. T\u00e1 dh\u00e1 phr\u00edomhchine\u00e1l bratphortach ann.
