Autumn has come in Daisetsuzan mountains ridge.

Mt.Kurodake　autumn leaves report

This morning temperature at Kurodake Ishimuro was 0°C, it was colder than weather forecast. (Hakuun Hut was 2°c)
For a while the temperature will stay 3~4°c.

These temperature made “Arctous alpina var. japonica” at the top of Mt.Kurodake and Mt.Ponkurodake so beautiful red.
Some are mad red, some are red and orange mixed color.
They are amazing.

“Sorbus matsumurana” at northeast slope of Mt.Kurodake ~Ohatidaira is turning red a little. (Compering with last post 8/27)
But most of them are still green.

On the whole all plant’s leaves are tuning from green to yellow green.
(Please check our homepage ‘Observation at a fixed point in Mt.Ponkurodake’)

This year’s autumn leaves are moving a little faster than last year.
But it is ok.
We hope we can see these beautiful autumn leaves for a long time.

About the trail to Mt.Akadake
Some leaves of “Sorbus matsumurana” start to turn red from Daiichi kaen to Daiyon sekkei.
Weather forecast says temperature won’t go up rapidly, so in a week or in ten days you can see beautiful autumn leaves there.

It has been hot in flatland.
But daytime’s temperature at the ridgeline of Daisetsuzan mountains is sometimes 1~9°c in August.
In these days strong wind blows.
When you go to mountains, please prepare something warm to wear.
You need a knit cap and gloves and a jacket.

Most of leaves are green.

About the slope of Mt.Kurodake
Summer flowers are still blooming.
Leaves of “Hypericum kamtschaticum Ledeb”, “Thalictrum aquilegiifolium var. intermedium Nakai” and “Spiraea betulifolia” start to turning red.

About the summit of Mt,Kurodake~Mt.Ponkurodake
Some Geum pentapetalum are so beautiful red to see.

About Kumonodaira
Most of “Geum pentapetalum” has fluff.
But some of them have very red leaves.


Comparing last year’s post, about “Geum pentapetalum” coloring is later than last year.

But it might change depends on climate.
Weather forecast says it will be 8~9°c at high mountains on August 29th.
So We guess leaves are turning slowly.
