I am the source of life
Cari Amici (Gruppo Humus),
Ho una cattiva e una buona notizia.

Cattiva: il vento ha buttato giù metà delle foreste alpine italiane
Buona: vivo in una regione governata bene. Il Presidente della regione ha chiamato il direttore del dipartimento Territorio e Sistemi Agro Forestali dell'Università di Padova e gli ha detto: "mandami un piano d'azione".

Non esistono più destra o sinistra ma gente che fa e gente che discute come bisognerebbe fare. Purtroppo oggi le persone che fanno sono come Trump. Non dico che fanno sempre bene, e quando fanno male sono contro di loro, ma è importante fare. Il diavolo del secolo non si chiama Trump ma ipocrisia.

Tornando al problema, il direttore del dipartimento ha riunito i colleghi ed ha chiesto a tutti di mandare delle proposte concrete da portare al Presidente.

Il suolo, che dovrà rigenerare la foresta caduta, è molto importante e noi specialisti del suolo potremmo giocare un ruolo determinante. Ci sono delle pubblicazioni che dicono che per rivitalizzare il suolo si puo' distribuire del cippato. La ramaglia di certo non manca. Ma, come sempre, le cose non sono semplici. Se il sistema di humus = la rete biologica che vive nel suolo, è quella sbagliata per il legno, aggiungere del legno da digerire potrebbe danneggiare o addi!rittura bloccare il suolo e la rinnovazione del bosco. Bisogna ragionarci sopra bene. In generale dove troviamo un sistema Mull o Amphi, il cippato sparisce in poco tempo e fa bene, in altri casi fa male. Ho chiesto aiuto a specialisti canadessi e francesi.

Mandatemi il vostro pensiero, che proviamo a mettere giù qualcosa di utile.

Mr. Humus
Dear Friends,
I have ugly and good news.
Ugly: a week ago, the wind made some deaths and threw down a part of the Italian forests (Fig. here over).
Good: I live in Veneto, a region led by a wise president. He is an agronomist who graduated at the University of Padua and in my department. He wrote to the today director of the department and told him: "for our forests I will do what you advise me, send me an action plan".
(To amaze you, I also say that the party that directs the region is similar to that of Trump - which in Italy is made of two parties, 5 Stars and Lega Nord, people asking for changes -, and this made me think a lot. There are no more left or right, but those who do things and those who talk about doing them. Politically rather leftist, I belong to those who do things which today, unfortunately, are like Trump. I did not say that they always do the right things, and when they are wrong I put myself against them, but it is important to DO, not to discuss too much about how. The evil of the century is not Trump, but hypocrisy.)
Back on the problem, I wrote to the director of the department: soil is a crucial aspect of the plan; if he needs ideas and action, I am ready and behind a group of soil specialists, all of you. We can turn disaster into action against global warming. He seemed very interested.
The soil is the digestive system of the forest. The new forest will start from the ground. Can we use fallen wood to feed the ground? There's so much of this. I was thinking of branches and wood fragmented (from unusable trees).
We have published our thought about the fragmented wood in Humusica 2, article 16. I have just bought a very good book ("De l'arbre au sol, les Bois Raméaux Fragmentés", written by Gilles Domenech and Eléa Asselineau, in Cc of this letter), but it is written to feed agricultural soils. I thought I would find information even on forest soils (the authors are Canadians, and the forests affected by the disaster in Italy are mostly coniferous: I contacted them yestray).
My thought:
1) to distribute fragmented wood on the forest soils affected by the event, after taking away the rest of the biomass, should work well below 1000 meters above sea level, with MULL or AMPHI humus systems.
2) above 1000 meters we pass in MODER or in thick AMPHI systems. The risk is to block the systems and stop their natural regeneration. I'm reading another good book ("Jamais Seul", by Marc-Andre Selosse, also in Cc: I discovered with great pleasure that this renowned author is very convinced of the role of the soil as a digestive system of all ecosystems !!!) and I hope to find in this book information on fungal digestion of litter in cold coniferous environments.
I am awaiting your comments. Send me bibliographic material and ideas/possible actions. You will be in the game. If we get convincing and good ideas, there are also funds to make them happen. It would be our first collective work. It will be very useful and could do school.

FIG. Wind and forest damages, October 29th 2018
Riassunto
On the left, interesting Bibliographic References
Following the bibliographical indications collected so far (essentially the precious work of Klaus & Co) we can try to go further, not proposing a general action, but different actions depending on the characteristics of the forests.

1) To subdivide A) very natural forests, B) forests subjugated to natural forestry and C) forests subjected to more impacting cuts = of production;
2) to propose a subdivision in a) low damaged forests (shaved by wind in holes or in any case less than 25% of coverage), b) medium damaged forests (shaved in holes or in any case less than 50% of coverage) and c) highly damaged forests (shaved by wind to the ground on larger surfaces);
3) And finally, what to do in these forests (example: low damaged Natural forest = Aa):
- Aa: do nothing;
- Ab: remove only the stems of the dominant diameter classes, in order to balance the composition of the crashes;
- Ac: remove at least half of the drums;

- Ba: do nothing if Mull or Biomacroamphi; remove the stems in other cases;
- Bb: remove half of the stems and fragment half of the branch only on Mull or Biomacroamphi; in other cases do not fragment the branch;
- Bc: remove all the stems and fragment half of the branch only on Mull or Biomacroamphi; in other cases do not fragment the branch;

- Ca, Cb, Cc: remove all the stems and fragment half of the branch in all cases.

A new basis on which to reason. To you to play. Hi, Augusto.
Seguendo le indicazioni bibliografiche raccolte finora (essenzialmente il prezioso lavoro di Klaus & Co) possiamo provare ad andare oltre, non proponendo un'azione generale, ma azioni diverse a seconda delle caratteristiche delle foreste.

1) Suddividere A) foreste molto naturali, B) foreste soggiogate alla silvicoltura naturale e C) foreste sottoposte a tagli più forti, di produzione;
2) proporre una suddivisione in a) foreste poco danneggiate (rasate dal vento in buche o comunque che hanno perso meno del 25% della copertura), b) foreste mediamente danneggiate (rasate in buche o comunque che hanno perso meno del 50% di copertura) e c) foreste altamente danneggiate (rasate dal vento a terra su superfici più grandi);
3) E infine, cosa fare nelle diverse foreste (Aa =foreste nuturali poco danneggiate):
- Aa: non fare nulla;
- Ab: rimuove solo i fusti delle classi di diametro dominante, al fine di bilanciare la composizione degli schianti;
- Ac: rimuovere almeno la metà dei fusti;

- Ba: non fare nulla se Mull o Biomacroamphi; rimuovere i fusti negli altri casi;
- Bb: rimuovere metà dei fusti e frammentare metà della ramaglia solo su Mull o Biomacroamphi; in altri casi non frammentare i rami;
- Bc: rimuovere tutti i fusti e frammentare la metà dei rami solo su Mull o Biomacroamphi; in altri casi non frammentare la ramaglia;

- Ca, Cb, Cc: rimuovere tutti i fusti e frammentare la metà dei rami in tutti i casi.

Una nuova base su cui ragionare. Adesso tocca a voi. Ciao, Augusto.

Taking an example from Trump, an economist in our group says that these are not things for soil ecology professors. That we are not talking about biodegradation, litter and worms, but hundreds of thousands of cubic meters of lumber to be taken to a sawmill to make businesses and mountain people live.
We must admit that he is partially right. However, I would like to tell him that the human biological future of the economy of this mountain region depends also and above all from the soil of this mountain.

Let's do things in order: 1. the professors put down a plan for the restoration of the forest from the soil; and 2. following this plan, companies will make all the money they want to run the local economy.

We are lucky, we have a president of the Region who is an agronomist and understands these things, specialists in the world of soil biology and soil-vegetation relationships to implement a plan of action in the Italian region richer in business.
Prendendo esempio da Trump, un economista del nostro gruppo dice che queste non sono cose da professori di ecologia del suolo. Che non stiamo parlando di biodegradazione, lettiera e vermi, ma di centinaia di migliaia di metri cubi di legname da portare in segheria per fare vivere le imprese e la gente di montagna.
Bisogna ammettere che ha ragione anche lui. Pero' dirgli che il futuro umano biologico dell'economia di questa regione di montagna dipende anche e soprattutto dal suolo di questa montagna.

Facciamo le cose in ordine: 1. i professori mettono giù un piano per il ripristino della foresta a partire dal suolo; e 2. seguendo questo piano, le imprese faranno tutti i soldi che vorranno per fare girare l'economia locale.

Siamo fortunati, abbiamo un presidente della Regione che è un agronomo e capisce queste cose, gli specialisti al mondo della biologia del suolo e dei rapporti suolo-vegetazione per attuare un piano di azione nella regione italiana più ricca di imprese.
