<Series> Yuichi Kaneko ・ Square Mountain Story (1) on alpine plants

What many mountain climbers think of when they hear "Alpine plants" is that they make up a flower field with a cluster,Shinano Kinbai,Hakusanichichie,ChingrumaI guess that is not a major part.

on the other hand"The queen of alpine plants'If it is said
everyone"Comics"I will answer.

Dicentra (Komakusa) (Popidaceae Dicentra)
(Scientific name: Dicentra peregrina)

It has become so major now, and many people are aware of the fact that it has come to the eye in many places unexpectedly.
Although the protection of the habitat has progressed and the manners of the climbers have improved as well, there are also results that are often planted as mountain and grass gardens at mountain sightseeing spots in various places.

But,The mountain of natural habitat in Japan is about 20 in the whole countryIt is said that it is a very valuable plant after all.

In the Southern Alps and Central Alps, it is already considered wild extinct,Things found in Mt. Kiso Komagatake and Mt. Hoken are propagated in a mountain hut and a forestry station.

In Mt. Tarumaesan in Hakusan and Hokkaido, etc., removal work is carried out for the purpose of preserving the original ecosystem because it is apparent that artificially grown horticultural species are produced..

No matter how beautiful it is, natural habitats and horticulture must be well separated.

Mountains where the locality of Dicentra is famous are in many places north of central part.

Other,Mt. OntakeYatsugatake,Kusatsu Shirane Mountainetc.

It is surprisingly limited in TohokuAkita Komagatake, Zao,Mt. IwatesanEtc, even in HokkaidoMt. Taisetsuzan,Shiretokodake,MeakanFor example, it is a plant whose habitat is limited unexpectedly.

Well, look at the names of these habitats,
Did you notice any tendency?

I'm still trying my best to reach the end of 8 (North Yatsugatake Neishidake 8 Moon)

Yes, you can enjoy Okesa Persimmons in the form of
Other than the Northern Alps, everyone is a volcano.

The ground most favored by Diomax isZare-like fine area like a volcanoIt seems like
In areas other than volcanoes, Mt. Tsubakurodake and Mt. Eboshidake grow on weathered granite gravels, and even on main islands such as Hakuba and Mt.

Dotted growth on a slight sand area between volcanic rocks (Mt. Taisetsuzan 7)

Dixa is"The queen of alpine plants"It is said that not only the beauty but also the rarity that people do not flock to other plants will feel noble and noble.

Grows in volcanic desert (Yunomaru Kogen XNUM X)

However, why is it possible to create a harsh environment like this kind of gravel?

People feel that they have unmatched strength and loneliness and call it "queen" etc., but it may actually be due to its "weakness" in fact that Dixa grows on barren ground Hmm.

In other words, in flower gardens and grasslands where a large variety of plants are mixed, many plants compete for survival and fight each other harshly in a limited space.

Dicentra seems to have chosen a way to live on a barren sandbank that can not be won in such survival competitions and no one has no choice.
And it's not just a gravel, it's an unstable ground where your feet will crumble if you step in.

In shallow plants and tall plants, the soil is fragile and strong winds will cause it to fall over quickly.
The sunny alpine ridge has a desert-like environment, with intense UV radiation and dryness in summer, and even heavy snow in winter when the snow is blown away.
And it's an unstable and nutritious gravel that breaks down constantly.

Dixusella is a low-profile so that it can grow fine leaves and withstand strong winds, and it has deep roots that reach up to more than 1m, and also resists movement of gravels on slopes.
Even in a sandy area where the water content is extremely low, the dew and mist are stored in the finely intertwined leaves and dry by deep roots.

"The queen of alpine plants" was a lonely queen who had neither a home nor a servant.

The small diam, which you find suddenly on the high ridges of the mountain, can be very calming, but the group you have seen so far has been wonderful.

The name also spreads on Mt. Taisetsuzan Mt."Comics flat"Then you can see the broad diocesa community that was set up like a Japanese garden on a gently rolling plateau.

In terms of the slope of the volcano,Akita Komagatake's "Great Porcelain"Then, the group stock of dicentra spreads over a wide slope is a masterpiece.
Here is the time before the diam blooms"Takanes Mille"Are blooming all at once, and 2 species that prefer similar habitats are also parting and coexisting in the season.

For those of you who can not easily see the ridge lines of the Northern Alps,Asano outer ring near the hot spring Maruyama "three-way peak"There is a protected area, and you can easily see the climax.

Cluster of three-way peak (Yuno Maru plateau 6 month)

Dicentra was collected from ancient times as a valuable herb, and it has been threatened with extinction, such as Mt. Ontake or Mt. Kaikomaga, so keep in mind that alkaloids are contained in all grass and are toxic.

However, there is also a butterfly that prefers this dimorpha to be a herbivorous herb for larvae, or that it also likes beggarworms.

Taisetsuzan and the Tokachi mountain range are "Usubaki butterfly" grown only at high places.

The butterfly itself is a rare and endangered species and a natural monument only for its special ecology.

It is connected with the survival of the species by riding on the rare survival of Dicentra that survived the harsh environment, so we listened to the voice of God of creation for what kind of path of evolution led to this survival strategy. I would like to
