DREVO Heritage Timber Reserve

Concept

Trees diametermore than 80 cmare the most valuable resource of the programDREVO Timber ReserveSuch trees have grown for many decades or centuries, developing a unique wood structure that reflects the climatic history of the region and the genetic characteristics of the population.

They cannot be considered as ordinary timber. Each such trunk becomesindividual natural heritage siteand requires its own digital passport, storage program and future use.

The main principle:

Each large tree trunk is a natural monument and a strategic resource for future generations.

Why are large trees unique?

Trunks with a diameter of more than 80 cm have a number of advantages:

high proportion of mature heartwood;

stable internal structure;

large defect-free areas;

high artistic value;

rich dendrochronological information;

the ability to manufacture large-sized products without gluing;

high potential for long-term storage.

In addition to their material value, such trees are of scientific interest for studying the history of climate, forest growth and genetic diversity.

Sources of income

Only trees obtained through legal and environmentally sound means are sent to the reserve:

emergency trees;

windfall after storms;

flood discharges;

trees removed during river restoration;

trees that pose a threat to infrastructure;

individual trees during sanitary measures;

wood extracted during the reconstruction of hydraulic structures.

Program does not provide for the felling of old-growth trees solely for the purpose of creating a reserve.

Preliminary examination

Each barrel undergoes individual diagnostics.

Geometry

Measured:

length;

butt diameter;

apex diameter;

ovality;

taper;

volume.

Internal structure

The following are carried out:

acoustic tomography;

ultrasound examination;

resistographic control;

selective core analysis (if necessary).

The following are determined:

hidden rot;

internal cracks;

cavities;

wood density;

state of the core.

Biological assessment

The following are recorded:

fungal infections;

insect damage;

condition of sapwood;

condition of the heartwood.

Digital passport

Each barrel receives a unique identifier.

The passport includes:

GPS coordinates of the growing location;

date of natural fall or removal;

reason for deletion;

breed;

age;

diameter;

length;

mass;

photographs;

3D model;

examination results;

storage recommendations;

expected reserve class.

Individual storage

Unlike ordinary wood, large trunks are not stored in rows.

Individual trays are created for them.

Each lodgement has:

own number;

depth;

fixation system;

access route;

control sensors.

Preparing the bed

Before laying, the following is performed:

site clearing;

scrap metal removal;

leveling the base;

device of a soft mineral cushion;

installation of side stops;

preparation of attachment points.

The stock must prevent the barrel from rolling or deforming.

Fixation system

For heavy barrels the following are used:

stone ballast blocks;

mineral anchors;

inert durable slings;

guide trays;

partial cover by stable bottom sediments.

The use of large quantities of steel chains is not advisable due to corrosion.

Controlled dive

The immersion is carried out gradually.

Used:

River Cargo Platform Heavy;

River Rover Recovery;

lifting air cylinders;

Automatic buoyancy control.

The barrel is constantly monitored:

on the move;

by dive rate;

by tension of slings;

according to the position relative to the bed.

Monitoring

Each premium barrel comes with advanced controls.

Measured:

temperature;

water level;

oxygen content;

barrel position;

siltation rate;

condition of fastenings.

The examination is carried out:

annually remotely;

every 5 years robotically;

control studies - according to a separate program.

Planned shelf life

Class B

50–100 years.

The highest quality trunks with a diameter of 80–100 cm are used.

Class A

100–300 years.

Only the best specimens are sent.

Use after extraction

Once the wood has matured, it can be used to create objects that will last for centuries.

Priority areas:

Architecture

columns;

but;

ceilings;

temple structures;

public buildings.

Art

monumental sculpture;

art panels;

museum exhibits;

thread.

Musical instruments

After assessing the condition of the wood, it is possible to use individual blanks for the production of:

concert grand pianos;

organs;

harp;

violins;

cellos;

guitar.

Furniture

Manufacturing of unique products:

large countertops;

libraries;

offices;

stairs;

interior panels.

Restoration

Creating recovery material:

historic buildings;

wooden bridges;

temples;

architectural monuments.

Genetic archive

From each tree the following are saved:

seeds (if any);

herbarium specimens;

leaf samples;

wood samples;

data on the place of growth;

dendrochronological samples;

If possible, DNA samples.

Thus the tree becomes a partDREVO Forest Genetic Archive, uniting the material and genetic heritage of forests.

Scientific value

Large trunks allow for the study of:

climate change;

history of droughts;

major fires;

flood periods;

air pollution;

forest growth rates;

the impact of ecosystem restoration.

Robotic maintenance

The following services are involved:

DREVO River Rover Scout

examination;

3D mapping;

sonar scanning.

WOOD River Rover Recovery

immersion;

service;

extraction.

River Cargo Platform Heavy

transportation.

Living Mountain Observatory

environmental monitoring.

Mountain Digital Twin

digital twin of the site.

WOOD AI

timber condition forecast;

planning of extraction times;

analysis of long-term changes.

DREVO Prize Fund

Trunks with a diameter of more than80 cmIt is proposed to allocate into a separate category:

DREVO Heritage Giants

Each specimen is considered as an individual object of natural heritage, and not as ordinary wood.

Their number will be limited, but they are capable of becoming the basis of an international woody heritage fund, uniting ecology, forestry, history, architecture and culture.

Project mission

Working with large-sized timber inDREVO Timber ReserveThe project is aimed not at creating a warehouse of valuable logs, but at preserving unique trees as natural and cultural capital. Such trunks carry information about the past of forests and climates and can become material for projects designed for generations to come, provided their selection, storage, and subsequent use are based on scientific monitoring and responsible environmental management.
