Use of swamps for DREVO Timber Reserve

Use of swamps for DREVO Timber Reserve

DREVO Living Mountains' Wetland Heritage Repositories

Concept

Within the frameworkDREVO Living MountainsRestored wetlands can not only store water, purify runoff, sequester carbon, and support biodiversity, but also serve as long-term storage sites for specially selected timber.

Constant humidity, weak water movement, stable temperature and limited oxygen availability in the deep bottom layers create conditions for the slow preservation of wood.

However, the swamp must not be turned into a storage area. The wood reserve must be integrated into the swamp ecosystem so that:

do not disturb the movement of water;

do not damage the peat layer;

do not block channels;

do not displace native species;

do not degrade the quality of water;

not create a fire hazard during the drying period;

do not interfere with the natural development of the swamp.

The main principle:

DREVO Timber Reserve must exploit the stability of the swamp without destroying the swamp itself.

Why are swamps suitable for storing wood?

Properly selected wetlands have several important properties.

Constant humidity

Wood does not go through frequent cycles:

getting wet;

drying;

cracks;

re-wetting.

Stable water saturation is much more important than just the presence of water.

Limited oxygen supply

In deep water-saturated layers of soil there is usually less oxygen than at the surface.

This may slow down:

activity of wood-destroying fungi;

oxidative processes;

destruction of wood fibers;

activity of some aerobic microorganisms.

However, it's not possible to artificially deprive an entire body of water of oxygen. Localized areas with existing suitable conditions are used.

Stable temperature

The bottom layers of swamps are less susceptible to sudden temperature changes.

This reduces:

temperature deformations;

seasonal cracking;

the intensity of some biological destruction processes.

Soft bottom sediments

Peat-silt and clay-silt deposits are capable of:

gradually close the trunks;

hold them in place;

protect from currents;

limit exposure to oxygen;

reduce mechanical damage.

Limited flow

Unlike an active riverbed, a swamp reserve is less susceptible to:

removal of trunks;

wood collision;

impact flood loads;

erosion of fastenings.

What swamps can be used?

Not all types of bogs are suitable for DREVO Timber Reserve.

Restored floodplain bogs

The most logical option in the systemDREVO Living Mountains.

They are formed:

when seasonal flooding returns;

restoration of old riverbeds;

closing of drainage channels;

creation of floodplain shallow waters;

restoration of oxbow lakes.

Inside such a complex, it is possible to provide a separate deep wooden section in advance.

Swampy oxbow lakes

Suitable if you have:

constant water level;

sufficient depth;

poor water exchange;

stable bottom;

absence of drying out.

Forest swamp basins

Can be used for small local reserves if:

there are no rare marsh communities;

there is no risk of seasonal drying out;

secure access for monitoring is possible;

The wood does not disturb surface runoff.

Artificially restored wetland pools

This is the most manageable form.

The pool is designed in advance with division into:

natural swamp area;

open water area;

filtration zone;

wood reserve;

technological passage;

monitoring area.

Peat quarries after restoration

Depleted peat areas can sometimes be converted into wetland reserves.

Before use, please check:

peat stability;

depth;

acidity;

pollution;

gas formation;

hydrological connection with the surrounding area.

Which swamps should not be used?

Not suitable:

seasonally drying up swamps;

raised bogs with a delicate and sensitive water balance;

areas with rare plant communities;

breeding grounds of specially protected species;

active peat-forming zones of high natural value;

areas with strong gas emission;

swamps near industrial pollution;

wetlands associated with drinking water intakes;

areas of intense flood flow;

areas where timber may block natural channels.

Raised bogs should be treated with particular caution. Their hydrology depends on a delicate balance of precipitation, peat, and vegetation. Engineering interventions there are often unjustified.

Spatial structure of the bog reserve

It is recommended to divide the territory into several functional zones.

Zone A - natural core

Fully preserved for:

marsh vegetation;

birds;

amphibians;

invertebrates;

natural peat formation.

The placement of strategic timber here is not permitted.

Zone B - ecological wood

Here are left:

rhizomes;

branches;

individual trunks;

natural tree fallouts.

This wood is not intended for future harvesting. It becomes part of the ecosystem.

Zone C — DREVO Timber Reserve

Specially prepared sector for accounted timber.

He must have:

stable depth;

limited access;

marked rows;

bottom lodgements;

safe distances between trunks;

possibility of robotic examination;

route of future extraction.

Zone D - technological corridor

Used for:

River Rover Scout;

River Rover Recovery;

small cargo platforms;

installation of sensors;

controlled extraction of wood.

The corridor should not cross the most sensitive natural areas.

Zone E — buffer

Consists of:

reed communities;

sedge;

shrubs;

swamp forest;

filtration shallows.

The buffer protects the reserve from:

pollution;

winds;

surface runoff;

access of people;

temperature fluctuations.

Construction of the wood sector

Bottom lodgements

The trunks should not be thrown haphazardly to the bottom.

The following are created for placement:

shallow longitudinal ravines;

wooden or mineral guides;

stone stops;

soft clayey-silty bases.

The trunk must be stable, but accessible for future inspection.

Longitudinal laying

Wood is placed mainly:

parallel to the natural movement of water;

in rows;

with intervals;

by breed;

by year of bookmarking;

according to the expected extraction time.

Transverse laying is only permissible where it does not impede water exchange.

Layered placement

In large reserves, several levels are possible:

lower historical reserve;

average long-term reserve;

upper research reserve.

Between the levels a layer of stable mineral or silt material is provided.

It is not possible to create excessively high wood mass, which can change the bottom relief and the direction of the water.

Methods of fixation

To hold the trunks the following are used:

stone loads;

bottom mineral anchors;

wooden supports;

partial silt coverage;

neutral synthetic slings with long service life;

removable frame cassettes for particularly valuable samples.

The use of ordinary steel should be limited due to corrosion.

Biodegradable fasteners are only suitable for the initial stage until the wood is saturated with water and stabilized.

Wood preparation

Before laying, each trunk is inspected.

Team

The following timber is sent to the reserve:

valuable species;

free from deep rot;

no industrial pollution;

of sufficient diameter;

of known origin;

suitable for long-term storage.

Cleaning

The following are removed:

metal elements;

wire;

plastic;

contaminated bark;

residues of chemical coatings;

dangerous objects.

Complete bark removal is not always necessary. The decision depends on the species and the research program.

Scanning

The following are recorded:

geometry;

defects;

cracks;

density;

humidity;

end structure;

position of knots.

For particularly valuable trunks, a complete 3D model is created.

Digital passport of the swamp reserve

Each barrel receives an individual entry.

The passport includes:

unique number;

breed;

origin;

date of felling or cutting;

reason for deletion;

age;

length;

diameter;

weight;

coordinates;

laying depth;

sector and row number;

photographs;

3D model;

type of fastening;

date of next examination;

Estimated date of possible extraction.

The data is combined into:

Mountain Digital Twin;

Living Mountain Observatory;

DREVO Heritage Timber Bank.

Monitoring of the swamp reserve

Controlled by:

water level;

water temperature;

bottom layer temperature;

dissolved oxygen;

pH;

electrical conductivity;

oxidation-reduction potential;

silt thickness;

position of the trunks;

condition of fastenings;

change in marsh vegetation;

gas formation;

water quality.

Роль Living Mountain Observatory

The system installs:

level sensors;

oxygen probes;

temperature chains;

wood motion sensors;

cameras;

weather station;

water quality control stations.

In case of a critical change of mode, the system reports:

lowering the water level;

drying out;

moving trunks;

pollution;

a sharp change in the oxygen regime;

fire risk;

flood damage.

Robotic maintenance

River Rover Scout

Performed by:

periodic inspection;

sonar mapping;

checking the position of the trunks;

measurement of water parameters.

River Rover Recovery

Used for:

laying large trunks;

position adjustments;

replacement of fasteners;

selection of control samples;

future timber extraction.

River Cargo Platform

Delivers timber and equipment to the storage area.

For shallow swamps, a lightweight or amphibious version is used.

River Rover Restore

Forms:

lodgements;

coastal plantings;

protective biofilters;

technological passages;

marsh vegetation after completion of the laying.

Fire safety

The swamp reserve is safe only if the water level remains high.

When it dries out, risks arise:

peat fires;

wood damage;

destruction of fastenings;

accelerated decomposition;

unauthorized access.

Therefore, the following is provided:

minimum permissible water level;

reserve feed channels;

adjustable water retaining bridges;

peat temperature sensors;

remote monitoring;

emergency flooding of the sector.

The system cannot be used as an excuse for artificially flooding valuable dry ecosystems.

Impact on carbon balance

The strategic reserve stores carbon inside the wood for the long term.

However, environmental performance should be assessed on a full balance sheet:

emissions during transportation;

construction of reserves;

changes in marsh hydrology;

possible methane emissions;

peat preservation;

storage duration;

further use of wood.

The top priority remains preserving the existing peat and natural bog ecosystem. The timber reserve should not increase greenhouse gas emissions by destroying the bog.

Research sectors

Long-term experiments can be carried out on individual small plots.

Compared:

different breeds;

depths;

types of bottom sediments;

acidity;

mineralization;

degree of silt coverage;

fixation methods;

aging periods.

Control samples are extracted through:

5 years;

10 years;

20 years;

50 years;

100 years.

This creates a scientific basis for predicting the quality of future bog wood.

Connection with floodplain restoration

The most effective model occurs when DREVO Timber Reserve is designed simultaneously with floodplain restoration.

Subsequence:

historical hydrology is being examined;

old sleeves are restored;

seasonal flood zones are created;

swamps are being restored;

natural nuclei are isolated;

a separate wood sector is being designed;

the first batch of barrels is laid;

vegetation is restored;

long-term monitoring is enabled.

Thus, the storage facility becomes part of the overall natural engineering architecture.

Possible economic model

The swamp timber reserve should not be used for rapid commercial logging.

Acceptable wood sources:

emergency trees;

wood after floods and storms;

material removed during riverbed restoration;

part of the wood during sanitary measures;

trees removed during infrastructure reconstruction;

surplus after mandatory preservation of ecological wood.

The reserve can be financed through:

nature restoration programs;

climate adaptation funds;

long-term environmental bonds;

cultural funds;

scientific programs;

DREVO Heritage Timber Bank.

Distribution of wood during wetland restoration

Recommended logic, not a fixed standard:

the bulk of usable wood remains in the ecosystem;

the commercially viable part is used in current projects;

a small selected share is sent to the strategic reserve;

Damaged small wood is used for fascines, biomats, mulch and soil formation.

The percentage is determined separately for each site after an environmental survey.

Main risks

Drying up of the swamp

Leads to contact of wood with air and increases fire risk.

Changing hydrology

Large amounts of wood can block the flow of water.

Methane emission

Changing the amount of organic material can affect anaerobic processes.

Loss of biodiversity

Incorrect placement can destroy natural habitats.

Illegal extraction

Valuable guns can become the object of theft.

Unavailable for decades

Without technological corridors, the reserve may be virtually impossible to service.

Legal uncertainty

It is necessary to secure ownership, protected status and the procedure for future use in advance.

Recommended pilot model

It is recommended to create a small reserve for the first pilot:

The final dimensions are determined only after a hydrological and ecological survey.

Criteria for a successful wetland reserve

A project is considered successful if:

the natural water regime is maintained;

the area of ​​valuable wetland communities is not reduced;

the wood remains completely water-saturated;

the trunks do not move;

water quality does not deteriorate;

the peat layer is not destroyed;

the reserve is available for monitoring;

data is stored for decades;

the place has long-term legal protection;

The conservation value of the territory remains higher than the economic value of the timber.

Mission

Use of swamps forDREVO Timber Reservetransforms some of the timber obtained from floodplain and forest restoration into a long-term resource for future generations.

But the project's goal isn't to fill swamps with tree trunks. Its purpose is to create small, controlled, and scientifically validated tree sectors within a larger living ecosystem.

In this approach, the swamp remains first and foremost:

water accumulator;

natural filter;

carbon storage;

biodiversity area;

protection from floods and droughts.

And only after these functions are preserved can it additionally become part ofDREVO Heritage Timber Bank— a centuries-old bank of woody heritage, created not at the expense of nature, but through its restoration.
