Is trá ghainmheach é loch dumhcha a chruthaíonn droimneachtaí de bharr na gaoithe.、Is swamps fionnuisce iad seo a fhoirmítear go nádúrtha nuair a shreabhann aibhneacha isteach i lagáin (Sagata, Niigata Prefecture, etc.)。Ardaíonn gaineamh faoi uisce mar chlaífort mar gheall ar shruthanna agus tonnta aigéin, ag cur bac ar an mbealach amach.、(Déantar é a fhoirmiú ar bhealach difriúil ó lochanna uisce goirt mar Loch Saroma agus Hachirogata)。Is aonán luachmhar é an loch dumhcha féin atá á chailleadh ar fud an domhain.、Timpeallacht atá luachmhar ó thaobh na bitheolaíochta de a chruthú。
Sand dune lake is a natural freshwater pond in a sandhill. It was shaped by wind. The wind had been carring sand and formed ups and downs, and then water stream into hollow places. It is not only very valuable existence itself in the world but also it gives important environment for biodeversity that’s being lost.
I Sráidbhaile Higashidori、Tá go leor “locha dumhcha” mór agus beag (13 swamps ainmnithe leo féin)。Roghnaíodh Higashidori Village, Dumhcha Sarugamori, agus Back Wetlands mar cheann de na 500 bogach tábhachtach sa tSeapáin (go deimhin, is féidir a rá go bhfuil an chuid is mó de Leithinis Shimokita roghnaithe ar an mbealach seo).。Dumhcha gainimh na foraoise moncaí seo (leithead 1-2 km)、Is meascán de dhumhcha gainimh é "Dumhcha Gainimh Shimokita" (fad iomlán 17 km) agus dumhcha a théann beagán intíre.、Cé nach bhfuil mórán eolais air, is é an dumhcha is mó sa tSeapáin é i ndáiríre.。Is é an chúis nach bhfuil sé ar eolas、Timpeallaíonn foraoisí cosanta gaoithe agus gaineamh na dumhcha.、Rudaí atá deacair do dhaoine a fheiceáil、Úsáideann an Aireacht Cosanta agus daoine eile an chuid is mó de le haghaidh láithreáin tástála ballistic, etc.、Tá sé seo amhlaidh toisc go bhfuil cosc ar iontráil.。
There are many dune lakes in Higashi-dori village. Named lakes are minimum 13s. Salugamori sandhill (1~2 km width, 17 km length) include the rear wetland in this village has selected one of 500 of the important wetland of Japan (Actually most of Shimokita peninsula is selected also). Additionaly, Shimokita sandhill (includ this Salugamori sandhill with the next ones) is really the biggest one in Japan. However almost all japanese don’t know of it. One of the reason is that this place is hidden from the roads by pine grove for protect the wind and the sand. The other one, here is off limited, because this ares has been useing for test site of trajectory of Ministry of Defence (MD).
Tá an loch dumhcha féin lasmuigh de cheantar na hAireachta Cosanta.、Is cosúil go n-úsáidtear cuid acu chun críocha iascaireachta freisin.。Mar sin féin, tá na foraoisí péine a úsáidtear le haghaidh cosanta gaoithe agus gaineamh tar éis fás níos mó freisin.、Tá go leor de na bóithre a théann go dtí an swamp ag imeacht.。Leanann meath daonra agus dul in aois anseo freisin.、Níl aon taighde acadúil á dhéanamh faoi láthair.。
These are out of the area of MD. A few lakes of it look as useing fishery sometimes but not often. Most of the roads to go there is being lost by growing thickly weeds and pine grove. Creasing depopulation and ageing there. Academic reserch stopped now.
Tá na grianghraif ó bhun go barr (socraithe ó thuaidh go deisceart)、Onuma、Marsh Sakyo、Aranuma。Athraíonn an méid agus doimhneacht beagán, ach tá siad go léir ina staid nádúrtha.。Is ribí róibéis mór é Onuma、Tá clú ar Sakyo-numa as Aegagropila Linnaei.、Cad a tharlaíonn anois nach bhfuil aon taighde déanta?。Tá domhain Aranuma 1-2m.、Tá Brasenia schreberi á bhaint.。
