| Euptelea polyandra in March 2021 for Yadoriki Forest |
The last time I’ve been to Yadoriki Water Source Forest やどりき水源林 was October 2020. The place was under heavy reconstruction from the destruction by typhoons in 2019. Early this month, I’ve returned there. The works are still on-going, but several parts are open to hikers.

The prefecture has almost completed the repair works for the forestry road from the gate of Water Source Forest. We can walk a paved road almost to the end of the former route. The collapsed section is detoured by a new cutting through the western slope of Mt. Nabewari 鍋割山 (ASL 1272.4m). The debris of landslides 2 years ago still remain, but they definitely become a small part of the course. I think finally families with kids can walk there now. Though, we forest instructors have recognized that the prefecture, i.e. the landlord, does not intend to recover the pavement fully that before reached to the starting point to the trail to Ameyama Pass 雨山峠 (ASL 957m). Anyway, there is undeniably an improvement.

Yadoriki Stream 寄沢, which caused flash floods and debris flows in 2019, is undergoing a substantial intervention. The Prefectural Office flattened the riverbed with heavy machinery and digging artificial water way in the middle. We seriously doubted how long such synthetic river can last if another monster typhoon hits the area again … In 2019, the Open Space near toilets suffered heavy erosion to be reduced in half. The place is still off-limit. We hope the site becomes accessible by summer holiday. But … could we find a place for kids to play with water, I wonder …?

is the flattened riverbed. We cannot see the stream from this point, but a fissure at the foot of these destroyed logs is artificially dug water way. |
 |
| Woooooooow. The stream looks like a road now … the construction work is going-on. |
The afforestation expanded on the western slope of Yadoriki Stream is receiving an intense forestry by thinning cedars and cypresses. The prefecture told us the place is accessible only for professional foresters who contracted the work from the Office. In 2019, Yadoriki Stream was flooded with broken and uprooted afforested trees. So, doing professional forestry up there to stabilize the slope certainly has a good reason. They say the work will continue at least until summer this year. We will be able to have a quiet autumn walk in Hadano Forestry Road 秦野林道 this year …

| The trolley
line for forestry to the western slope is fully operational now. |

| We
found lots of Astraeus sp. as well. They love gravelly place so that encountering them in Yadoriki of under-construction may not be surprising. |
Despite of massive civil engineering, I personally find the nature of Yadoriki Forest is recovering strongly. After the typhoons in 2019, I felt sad to find many decimated points where before beautiful mosses secretly but cheerfully sprouted their capsule to procreate. Now they are coming back, if not fully. Impressive. In Chinese character, mosses are written as 苔. It’s a hieroglyph. The top part which looks like a hat means “row of grasses.” The middle symbolizes “plow”, and the bottom is “mouth.” When a farmer starts his/her work in the spring, the first thing s/he normally does is plowing the ground like opening the mouth of soil. So, the Chinese character for mosses means “it’s the beginning of vegetation.” Yeah. Yadoriki Water Source Forest was covered with mountain debris two years ago. Aside from the endeavor of humans restoring the place, tiny mosses may be quietly taking a lead for the recovery of the forest ... Petit conquerors!

| I
think, they are Palamocladium leskeoides. Such delicate apparitions of mosses were gone after monster typhoons of 2019 … Now, they’re back! |

| The beloved
Racomitrium japonicum are recovering in Yadoriki. Hurrah! |
