砂丘湖 / Sand dune lakes-Wild life Shimokita-6

「砂丘湖」とは砂浜が風などによって起伏を作り窪みに川が流れ込むなどして自然にできた淡水の沼である(新潟県佐潟など海流や波によって海中の砂が堤防のように盛り上がり出口を塞ぐサロマ湖や八郎潟など汽水湖とは出来方も異なる)砂丘湖自体も世界的に失われつつある貴重な存在だが生物的にも貴重な環境を作っている

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.

東通村には大小多くの「砂丘湖」がある(名前がついている沼だけでも13ある)東通村・猿が森の砂丘・後背湿地は日本の重要湿地500に選定されている(実は下北半島のほとんどの部分がこの選定を受けていると言ってよい)この猿が森砂丘(幅1~2km総延長17km)と少し内陸に入り込んだ砂丘を合わせた「下北砂丘」はほとんど知られていないが実は日本最大の砂丘であるという知られていない理由は砂丘の周辺を防風・防砂林が囲み人の目に触れにくいことと大部分を防衛省などが弾道試験場等に使用し立ち入りを禁じているためである

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).

砂丘湖自体は防衛省区域の外側にあり一部はほそぼそと漁業利用などもされているようだしかし防風・防砂用の松林も大きくなり沼に通じる道の多くは消えかけている人口減と高齢化はここでも進み学術的な調査なども今は行われていない

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.

蕾丝花 / 蕾丝花(野生动物的下北5)

レースフラワーはただの雑草/Lace flower is just a weed
レースフラワー/ Laceflower

花边花朵溢出。一直到道路两侧、在房子里走来走去。在空置的地段中,就像一个带有种子的田地、盛开。每年的这个时候,这是Shimokita(尤其是在Higashidori村)的杂草。、到这次我还没有注意到。多年来,我已经这个季节还没有回到Shimokita。、我印象深刻。我认为在过去几年我不在的时候,它的增长急剧增加。。

There were so many laceflowres. Along every roads, surrounding the houses. It comes out in every vacant lots as a seeded fields. This flower is as typical one in Shimokita (especialy Higashi-dori villg) now, however I had not found it before. I felt it criticized me beautifully for not coming back home land for long time in this season. It may be planted for last few years and then reproduces rapidly, 我觉得.

“蕾丝花”是一般术语。我们还在现场检查了几种类型的花边花。。他们所有人基本上都是Cerae家族的花朵。、颜色、形状、茎上有或没有刺,等等。、有很多变化。现在在城市、显然这很受欢迎。当我看着它、颜色是白色的、粉色的、蓝色的、黑色的、显然种植了紫色的色调。价格从每瓶约90日元到近400日元。。如果1000万瓶在村庄开花,每瓶100日元、10价值数十亿日元的宝藏只会在风中摇摆。即使您说这是浪费,也不会开始。它在Shimokita的风中吹来、这可能是处理它的最正确的方法。

“Laceflower” is the generic name of some kind of lacy flowers. I find it away. It has several variations on colors, shapes, prickles etc, although basicaly beongs to umbelliferae. In this time it looks popular in a city. It has been planted white ones, pink, blue, black! in many fields. These Prices are about from 90 to 400 yen per each. If it may be sold 100 yen as well, and 10 milion ones in this village, so it makes 100 milion yen. It just waves everywhere by free. But it is just a calculation. In a sense, it may be the best way that you just receive the wind in Shimokita with these laceflowers.
