River ecological corridor

River ecological corridor

River Corridor— is a continuous natural system along rivers and streams, uniting the riverbed, coastal forests, floodplains, swamps and oxbow lakes into a single ecosystem. Within the frameworkDREVO Living MountainsThe river corridor connects mountain springs with the sea, ensuring the continuous movement of water, nutrients, organisms and energy.

The main task ismake the river a living ecological artery, not an artificial canal.

"A healthy river begins not in its channel, but in its entire corridor of life."

Main objectives

Restoration of natural hydromorphology of rivers.

Protection and restoration of floodplain forests.

Improving water quality.

Restoration of spawning grounds.

Creation of migration routes for fish and animals.

Reducing coastal erosion.

Restoration of swamps and oxbow lakes.

Increasing the river's capacity for self-purification.

Key elements of the River Corridor

River bed

The following are being restored:

natural meanders;

rifts;

braids;

deep holes;

stone thresholds;

gravel areas;

sandbanks.

Coastal forest

Priority trees:

alder;

willow;

elm;

ash tree;

poplar;

maple;

linden.

Main functions:

shading rivers;

water cooling;

strengthening of banks;

filtration of surface runoff;

input of organic matter.

Floodplain forests

Plots are created with:

oak;

elm;

I am a jasmine.

alder;

willow;

bird cherry.

Purpose:

flood water retention;

accumulation of fertile sludge;

increasing biodiversity.

Swamps and wetlands

The following are being restored:

floodplain swamps;

oxbow lakes;

temporarily flooded areas;

filtration zones.

Coastal meadows

The following are being formed:

honey meadows;

forage meadows;

bird areas;

natural hayfields.

Priority plants

Trees

Shrubs

viburnum;

hazel;

elderberry;

buckthorn;

honeysuckle;

hawthorn;

rose hip.

Aquatic plants

rug;

sedges;

reed;

arrowhead;

susak;

bur-reed;

air;

local species of water lilies and water lilies.

Animals

Fish

Habitats are being restored for:

trout;

grayling;

salmon (where it naturally occurs);

pikes;

perch;

chub;

barbel;

the gudgeon.

Amphibians

frogs;

frogs;

newt;

salamander.

Birds

kingfisher;

grey heron;

white heron;

ducks;

sandpipers;

Black Stork (in suitable regions).

Mammals

beaver;

otter;

muskrat (only in regions where its presence does not harm local ecosystems);

roe deer;

deer.

Engineering solutions from DREVO

Living River Banks

Strengthening the banks:

live willow stakes;

fascines;

wood mats;

root systems of plants.

Floodplain Reconnection

Restoring the river's connection to the floodplain:

seasonal flooding;

restoration of oxbow lakes;

restoration of floodplain lakes.

Woody Habitat Engineering

Accommodation:

large logs;

root stumps;

natural tree fallout.

Purpose:

fish shelters;

sediment accumulation;

formation of a diverse flow.

Gravel Spawning Zones

Creation:

gravel spawning grounds;

areas with fast currents;

oxygen zones.

Biofiltration Wetlands

Artificial and restored swamps purify water from:

excess nitrogen;

phosphorus;

suspended particles;

organic contaminants.

flood risk reduction;

reduction of coastal erosion;

restoration of fish migration;

increase in the number of aquatic and near-water animals;

improving the condition of floodplains and swamps;

formation of a sustainable river ecosystem.

The main principle

The River Corridor is not just a riverbed, but the entire living river valley.

In the systemDREVO Living Mountainsthe river corridor unitesWatershed Corridor, Slope Corridor, Mountain Springs Recovery, Floodplain Restorationand coastal ecosystems into a single, continuous network. This allows water to flow from mountain springs to the sea through resilient natural landscapes, simultaneously supporting forests, agriculture, biodiversity, and human well-being.
