Walking along Urikai river, Kikanko river and Satsunai river. 売買川、機関庫川、札内川沿いの散歩。
売買川堤防まで散歩。今年は雪が少ないので、真冬には普通歩いていけないところまで足を伸ばすことができます。1月5日には農業高校、畜大キャンパスを通って売買川の堤防を歩き、帰りは往路と違う道を通って帰ってきました。売買川の堰がしっかり凍っていました。その後の散歩の様子もこの項目に続けて載せることにしました。
Afternoon walk to Urikai river on January. Due to the very little snow in this year, I could walk to the place which is hardly accessible in normal years. The dam on Urikai river was frozen already. The views seen during my walk in the following days are also uploaded here.

Views along the bank of Urikai river to the north of Inada elementary school where I walked next day (January 6). A pair of merganser was swimming in Urikai river. In the last winter, I also saw the pair of birds here.
Views along the bank of Kikanko river where I walked next day (January 6). 農業高校の森を通って稲田小学校の北の売買川堤防まで歩き、その後機関庫川沿いの道を帰ってきました。売買川ではカワアイサのつがいが泳いでいました。
Evening views from Seiryu town where I live (January 7). Photos taken during my evening walk are uploaded here. This morning, I had a lecture of soil science for the junior course students as a part time lecturer. After the lecture, I read the reports of students, and then joined a mini-volleyball game in the lunch break. I think, having a lecture once a week is very ideal for me, because I have enough time for preparing and reviewing the lecture.
Views along the bank of Kikanko river (January 7). 夕刻の散歩。今日は1時間目に非常勤講師(別科土壌作物栄養学)としての授業があり、ささやかな仕事始めとなりました。授業後1時間半ほど学生さんたちが提出したレポートを読み、昼休みにミニバレーをしてから帰ってきました。1週間に1度の授業というのは理想的です。
Elm trees (January 8). In the afternoon of January 8, I walked along Kikanko river to visit "Harunire" park where the symbolic elm tree of Obihiro city is growing. Then, I came home passing through the eastern bank of Satsunai river.

Satsunai river near the bridge of express highway (January 9). In the afternoon of January 9, I walked to the post office of Kawanishi town around 3 km far from my house, then came back walking along the bank of Satsunai river. On the way, I walked down to the river shore and watched the flow of the river. It was quiet and beautiful. The time to the post office was around 40 minutes and from the post office was around 1 hour. By car, it takes only 10 minutes from my house. When I become old enough, I will abandon driving, then it will become very difficult to go to post office.

Road on Satsunai river bank and elm trees (January 9). 川西郵便局に用事があったので散歩がてら歩いて行き、帰りは札内川の堤防を歩いてきました。行きが40分、帰りが1時間くらいかかりました。帰り道は川岸まで降りて川の流れを見ていたりしたので時間がかかりました。車で行けば10分以内のところですが、年をとって車を運転できなくなったら、歩くことも困難なので困るだろうなと思います。
Stone and gravel excavation site and the volcanic ash layer appeared on the newly cut drain ditch (January 9). 堤防脇に側溝が掘られていました。薄い白い層があり、火山灰ではないかと思いました。

This afternoon, I walked from the southern end of the university field to north along the bank of Urikai river. The river was totally frozen in this part. The evening glow on my way home was also beautiful (January 14). 今日は売買川沿いを畜大の圃場の南の端から北に向けて歩きました。歩き始めの部分では売買川は全面が凍っていました。堰の凍り具合も2週間ほど前に見た時よりもさらに進んでいました。帰り道は夕焼けが美しかったです。

End of new year season by "Dondoyaki" ceremony at the local shrine. 川西神社でどんど焼き。
New year season ends with the ceremony of burning new year's door decoration in the shrine ("Dondo-yaki"). I walked to the near-by Kawanishi shrine, and returned the door decoration. The temperature was around minus 15 this morning.

Many people visited the shrine to incinerate the new year decorations.
Wild bird survey in the forest of Obihiro conducted by "Ezorisu no Kai". 帯広の森でエゾリスの会の鳥類調査に参加。
In the morning of January 20, I joined the wild birds survey in the forest of Obihiro conducted by “Ezorisu no Kai” (a volunteer group for learning wild lives in the forest of Obihiro and bringing up the forest). Today, seven members assembled and they were separated into two groups (4 and 3 people). The first group with 4 members had to survey the area two times, because the survey is usually conducted by 3 groups as a fixed rule. I was grouped in the first group and walked the survey course two times successively with other three members. I could enjoy the survey very much because I could see many kinds of birds, not only small birds but also an eagle. The survey finished before noon. After lunch, I walked to the forest of Obihiro Agricultural High School. I entered the wetland forest in the lower terrace area, where people seldom walk in. There, I could see another birds, for example, Eurasian Jay and Naumann’s Thrush.
1月20日の午前中はエゾリスの会が行なっている鳥類調査に参加しました。集まった人が少なかったので2班に分け、調査は毎回3班で15分おきに出発して行うことになっているので、今回最初の班はコースを2周することになりました。私はその2周する班に入りました。ゴジュウカラ、シジュウカラ、ヒガラ、ハシブトガラ、エナガ、コゲラ、アカゲラ、キバシリなどの小鳥に加えて、オジロワシも見ることができました。リスの活動も活発でした。そろそろ繁殖期だそうです。鳥類調査のあとは図書館に行って本の返却と借り出しを行い、午後はまた農業高校の森の中に散歩に行きました。機関庫川沿いではツグミとゴジュウカラを、農業高校の森のなかではカケスを見ることができました。

Lowland forest of Obihiro Agricultural High School. There are many fallen trees, as the soil layer is very shallow here.
The curator of the Obihiro Centennial Museum who walked together for the bird survey the day before yesterday (January 20), contributed an article titled “Spring is coming: Walking from town to forest and field.” to Hokkaido News Paper on January 22. When we walk in the forest in this season though it is still very cold, we can feel spring already in the breeding activity of wild animals (squirrels) as well as the swelling buds of trees in the strengthened sunlight one month after the winter solstice. In spite of such signs of spring, it has started snowing again. We, including wild animals and forest plants, have to endure the harsh winter still some more period.
1月22日の北海道新聞の夕刊に、一昨日の鳥類調査に同行させて頂いた帯広百年記念館の学芸員さんが「街から歩いて森へ原野へ・・・春が来る」と題して書いておられましたが、この時期森を歩くと、冬至から1ヶ月を過ぎて日差しも強くなっており、まだ厳寒期ではあるものの、動物や植物がすでに春に向けて準備をしていることを感じます。リスやモモンガは繁殖活動を開始し、木々の芽が膨らんできます。とは言え、明日はまたまとまった雪が降りそうです。春の気配は感じるものの、まだまだ人も野生動物も植物もあと少し厳しい冬を耐えなくてはなりません。
Walking into the swamp forest of Obihiro Agricultural High School. 帯広農業高校の湿地林を散策。
In the afternoon of January 25, I walked in the swamp forest of Obihiro Agricultural High School. In the mid-winter, grasses are covered with snow and I can have a good view in the forest. Swamp is also frozen and my shoes will not be wet as long as I walk carefully. However, bushes with thorns and withered trees sometimes block me from going forward. As there is also no human trail, I have to follow the footprints of foxes. For my return way, I walked along Urikai river and Kikanko river. I could see also various small birds along Kikanko river.
1月25日の午後は再び農業高校の湿地林を歩いてきました。この時期は下草が雪に覆われていて見通しがききますし、湿地も凍っているので靴を濡らすことなく歩くことができます。でも藪の中なのでトゲのある低木や枯れ枝が行く手をさえぎるところもあります。人の踏み跡も無いので、キツネの通り道が頼りになります。帰り道は売買川と機関庫側沿いを通って帰ってきました。機関庫川沿いではツグミ、ヒヨドリ、ムクドリなどを見ることができました。

Attending the walking lesson in the morning and walking alone along Urikai river in the afternoon. 午前中はウォーキング講習会、午後は売買川沿いを散歩。
In the morning of January 26, I attended the second walking class held at the sports center of the forest of Obihiro. We learned today the walking method using two stocks called “Nordic walking”. The lecturer told us that this method is very good because we can walk safely in good posture and the another merit is that we can enjoy communication during walking. Usually I walk alone in the very lonely place where I see nobody during walking. I am afraid that I might forget speaking Japanese some time. As the walking distance in the morning lesson was not enough for me, I went out for walking along the Urikai river in the afternoon.
By the way, the first walking practice class was held at the sports center of the forest of Obihiro on January 19. Last year I also attended the same class. The leader talked about the importance of practicing walking, and guided us how to warm up before walking, and taught us the good posture for walking. Then we walked together around the sports center. We could not practice the walking wearing snow shoes due to too little snow. The lecturer told us that we do not need to practice walking hard and even it is not necessary to walk every day, but it is important to keep the habit of walking for as many days as possible.
1月26日午前中は帯広の森スポーツセンターで行われたウォーキング講習会の2回目に行ってきました。今日は2本のストックを使って歩くノルディックウォーキングを教えて頂きました。正しい姿勢で安全に歩けるのでとても良い方法だとのことでした。また、何人かのグループで会話をしながら歩けるのも他のスポーツに無い特長だとのことです。確かにウォーキングはひとりだけでなく、誰かと一緒に歩くのも楽しいことと思います。私の日頃の散歩は一人だけで、しかも他の人にほとんど会わないようなところばかり歩いているので、会話を伴いません。そのうち日本語を忘れてしまうのではないかと心配になります。午前中のウォーキングは距離的に物足りなかったので午後からも売買川方面に散歩に行きました。
なお1回目のウォーキング講習会は1月19日(土)に行われました。その後毎週土曜日3回行われることになっています。雪が少なかったのでスノーシューを履いての講習は行われず、ウォーキングの意義、準備運動の仕方、歩く姿勢の指導、実際にスポーツセンターの周りを歩いてみるなどのメニューでした。ウォーキングというとスポーツの範疇で頑張らなくてはならないような気持ちになりますが、あまり頑張る必要はなく、体が温まる程度の運動を長続きさせることが重要との説明がありましたので、私も同感でした。

I walk from 1 to 2 hours a day as long as the weather is not so bad. I usually walk in the forest of Obihiro Agricultural High School and along Kikanko river, Urikai river, and Satsunai river.
私はお天気さえ良ければ毎日1時間から2時間の散歩をしています。ルートは近所の農業高校の森や機関庫川、売買川、札内川沿いの道を選ぶことが多いです。

For the people living in the northern region of Japan, especially Hokkaido, snow removal after the snow is unavoidable work. When they have to go to their office, they have to get up early and remove the snow before they leave their home. Now I am retired, and have enough time to remove the snow. However, it was Monday today and I had to go to the university to have a lecture as a part time lecturer, and I had to remove the snow before I left home and after coming back from the university. As the service of Obihiro city does not remove the snow on the side walk, I have to remove the snow on the side walk by myself. The winter in Obihiro is long. We have to wait still two more months until spring comes here.
日本の北国、特に北海道、に住む人にとっては、除雪は避けることのできない仕事です。出勤しなくてはならない場合、早く起きて出勤前に除雪をしなくてはなりません。私は退職したので、除雪をする時間はたっぷりあります。しかし、今日は1時間目から非常勤講師に行く日だったので、出勤前と帰ってきてからの2回たっぷりと除雪をしました。帯広市のサービスはよほどの雪が降らないと歩道の除雪はしてくれないので、家の前の歩道の除雪も私がやっています。春が来るまでまだ2ヶ月もあり、雪はまだまだ降ることと思います。

2月11日には連休を利用してわが家に来ていた次男と一緒に子供たちが育った大空団地と帯広の森の「もりのやま」に行ってきました。
I went out for walking after several days of discontinuance during the coldest days. Along the streams of Kikanko river, there were many footprints of children who played with ice on the stream. In the latter half of my walking path in the forest of agricultural high school, I could find only the footprints of wild animals.
2月15日には久しぶりに散歩に行きました。機関庫川沿いには子供たちの足跡がたくさんついていました。川の氷をはがして遊んだようです。農業高校の森の中の道の後半にはキツネの足跡しかついていませんでした。
Selective felling of needle trees in the forest of Obihiro by "Ezorisu no Kai". エゾリスの会による帯広の森の針葉樹間伐作業
I joined the activity of a volunteer group “Ezorisu no Kai”, which is carrying out various activities to survey and protect wild lives (animals, birds, trees and grasses) in the forest of Obihiro. We conducted the selective deforestation to reduce the numbers of 40 years old Korean Nut Pine which have grown too tall, shading the forest and preventing the growth of other native tree species.
On February 18, last year, we peeled off the bark of Korean Nut Pine trees at the height of chest in 20 - 30 cm width. In a few years from now, these trees will be withered and leaves will fall. We expect that more light will be shed on the forest floor and the growth of native local tree species will be promoted.
On February 17, this year, we felled down the selected needle trees to promote the growth of natural deciduous tree vegetation.

I came home from Myanmar to Obihiro in the afternoon of March 11. As I could not sleep well in the flight, I slept long in my house. In the morning of March 12, I found snow covering our place. My first work in Obihiro was removing the snow.
Also on March 16, we had snow again in Obihiro. I removed the snow around my house after the snow has stopped. However, most of the new snow melted in the afternoon, and I thought that I needed not to remove the snow.
For 5 days since I came home from Myanmar, I had been busy preparing for the meeting of the short-term experts held on March 14. As I was the last short term expert sent to Yezin Agricultural University in the fiscal year, I had such a tight schedule. Yesterday, I summarized my photos taken during my stay in Yezin Agricultural University and uploaded in this homepage (Recent photos No. 246 - 261). I also summarized the data obtained in my training and also uploaded them in the homepage. There are still more works to be done for correcting my teaching materials and for preparing the new materials, but these works will be done little by little from now.
On March 17, Hidaka mountain range was beautifully seen in the morning. Hidaka mountain range is the back bone of Hokkaido island. Sapporo is located beyond these mountains.
On March 18, I walked along the bank of Satsunai river, and on March 19, I walked along Kikanko river and in the forest of agricultural high school. Pheasant's eye was already blooming beside the stream. A fox was resting in the pasture field. Small birds and woodpeckers were active in the forest.
On March 20, graduation ceremony was held in Obihiro University of Agriculture and Veterinary Medicine today. I visited the seminar room of the junior course in the afternoon, and met the students whom I taught as a part-time lecturer.
In these 9 days since I came home from Myanmar, the season has changed rapidly from winter to spring in Obihiro.
Graduation ceremony was held in Obihiro University of Agriculture and Veterinary Medicine on March 20, 2019. I visited the seminar room of the junior course in the afternoon, and met the students whom I taught as a part-time lecturer.
Preparation of soil monolith and sprouts of early spring plants. 土壌モノリスの作製と森の山菜の芽生え。
As it was warmer than yesterday, I went to the nearby forest to prepare a soil monolith. The profile had been dug since last fall. The soil profile was still frozen and its surface was very hard. I am not sure whether it has been successfully prepared or not. It will also take time before the resin will be hardened. Afterwards, I walked in the forest. I could find the flower stalk of a butterbur (Fuki-no-tou), which is edible.

Woodpecker "Akagera", flower stalk of butterbur, wild mustard "Yuri-wasabi", water plant "Enkousou".
Dishes cooked from edible wild plants with the tea from Myanmar and Japanese Sake (rice wine). Tempura of "Fukinotou" (flower stalk of butterbur). "Fukinotou" cooked with meat, peanuts and miso. Boiled "Yuri-wasabi" (wild mustard).
On March 28, I went to the nearby forest to peel the soil monolith from the soil profile. As the surface of the profile had been frozen when I applied the resin, the resin did not penetrate into the soil enough and the monolith was not perfect. I am going to repair it by and by.
On March 29, I went to the soil profile site, and divided soil layers and collected some soil samples. A flower of pheasant's eye. Due to its parabolic structure, sun light and heat is concentrated to the central portion of the flower. Pollinator insects are attracted by the heat and pollen of the flower.
On March 30, I walked my routine course looking around the forest floor or along the stream. Swamp ash and walnut trees along the stream with still no leaves. The flow of Kikanko river. The vegetation is richer in the cliff side due to the nutrients flowing down the cliff from the upper terrace.
On March 31, I took a walk after 3:00. I went to see the colony of skunk cabbage near Urikai river. Flower stalks have already emerged, but it was still early for the flowering. The third photo shows a water plant, Caltha palustris var. barthei, along the Kikanko river.
I passed by the soil profile site again. In the other soil pit, gravel layer is obvious below the orange colored volcanic ash layer.
On April 8, I brought the students of junior course to the soil profile site for the class of soil science and plant nutrition practice. We observed two soil profiles there.
Comparison of the two soil profiles on April 8. Alluvial layer was more stony in the left soil profile.
This wetland is a part of the branch of Kikanko river very near to my house. I have not noticed this wetland until April 7, because it was hidden behind the bush beyond the pasture field. The lower photo is the white birch trees beside the pasture field.
I visited a small stream near my house and found skunk cabbage flowers have bloomed at last on April 12.
4月12日、近くの小川に水芭蕉の花がやっと咲きました。去年よりも1週間ほど遅かったです。
I took a walk this evening (April 14). In the daytime, I worked in my garden to remove the snow-protector from the garden plants. In the fields, plants are growing rapidly due to the warm temperature.

Biological survey along the Utsubetsu river. ウツベツ川の生物調査。
On April 20, I joined the activity of biological survey along the Utsubetsu river flowing in Obihiro city organized by the Obihiro Centennial Museum. Various fishes and insects were collected. Some of them were rare and environmentally important. A river improvement work is planned for this river in the near future. I hope the work will not affect the rich biota in this river.

去年までこのあたり一面にチゴユリが咲いていたのですが、今年は刈り払われていました。この官舎に住んでおられた先生が定年退職されたためです。草刈りをすればもとの植生がなくなりタンポポが生えるだけなのに、残念なことです。
Until last year, we could see "Chigoyuri" (Disporum smilacinum) here, but this place has been mown recently. A professor who lived near here prevented the mowing while she was teaching at the university, but she has retired this spring and left this place. After mowing, this place will be covered by dandelion. It is pity.

Soil profile and crops in the junior course field. 別科圃場の土壌断面と作物。
In the junior course field, I am conducting soil profile survey, and crop cultivation. Potato is growing well, though the planting of seed potato was delayed one week due to the long golden week. Performance of beans and radish is not good due to the very dry and hot weather during the past three weeks. Preparation of soil monolith was carried out on June 4. Flowers seen in the forest of Obihiro Agricultural High School are also added. Season of white flowers is coming to end.
