Unraveling the Fate of Western Polissia's Peatlands
Beneath the unassuming landscapes of Western Polissia lies an environmental powerhouse quietly performing miracles of climate regulation and biodiversity support.
These are the region's peatlands—waterlogged territories where ancient plants have accumulated over millennia, creating vast carbon-rich deposits that have effectively cooled our planet for centuries.
Carbon storage comparison per unit area
Peatlands are wetlands characterized by a naturally accumulated layer of dead plant material—peat—at the surface. This peat forms when organic matter accumulates faster than it decomposes due to a lack of oxygen in waterlogged conditions 4 .
Although they cover just 3% of the global land area, peatlands contain approximately 25% of the global soil carbon stock—twice the amount found in all the world's forests 4 .

The Western Polissia region represents one of the most significant peatland complexes in Europe, stretching across the borderlands of several Eastern European countries.
Its historical condition was one of vast, waterlogged expanses teeming with specialized plant and animal life. The region's peatlands have developed over thousands of years, creating a complex mosaic of bog and fen ecosystems.

Professor Stanisław Kulczyński led floristic and peatland research for the Polesie Drainage Meliorations Office 1 .
Contemporary researchers used Kulczyński's work as a baseline for measuring ecological change 1 .

How We Monitor Peatlands Today
| Tool/Method | Function | Application in Western Polissia |
|---|---|---|
| Historical Map Analysis | Georeferencing and digitizing old maps to establish past conditions | Tracking 100 years of change using Kulczyński's 1928-1933 surveys 1 |
| Vegetation Plot Surveys | Detailed inventory of plant species in defined areas | Assessing biodiversity changes in rich fens, poor fens, and bogs 1 |
| Eddy Covariance Towers | Continuous measurement of gas exchanges between peatland and atmosphere | Quantifying net ecosystem exchange (NEE) of CO₂ 5 |
| Automated Chamber Systems | Precise measurement of greenhouse gas fluxes from small areas | Comparing carbon dynamics across different microhabitats 5 |
| Water Level Loggers | Continuous monitoring of water table fluctuations | Correlating hydrological conditions with carbon emissions 5 |
| Radiocarbon Dating | Determining long-term carbon accumulation rates | Placing recent changes in context of millennial trends 5 |
| Remote Sensing | Satellite and aerial imagery analysis | Mapping overall peatland extent and degradation status 1 |
Only 28–42% of the original mire area has survived in a relatively natural state, with the rest converted to agricultural land, intensively used meadows, or peat mines 1 .
Between 1965 and 2023, the drained peatlands of Western Polissia may have emitted between 0.33 and 0.74 gigatons of CO₂ equivalent 1 .
Similar processes are occurring globally, with drained or burned peatlands accounting for approximately 5% of all anthropogenic greenhouse gas emissions 4 .
Estimated CO₂ emissions from drained peatlands (1965-2023)
| Peatland Type | Documented Changes | Primary Drivers |
|---|---|---|
| Rich Fens | Decline of specialist species; increase in nutrient-loving and drought-tolerant plants | Drainage, nutrient enrichment |
| Poor Fens | Relatively stable vegetation composition | Often located in less-drained areas |
| Bogs | High retention of natural characteristics | Resistance to change due to rain-fed nature |
| All Types | Replacement of rare species with common generalists | Habitat fragmentation and degradation |
Blocking drainage ditches and restoring natural water levels to stop carbon emissions and allow peat accumulation to resume .
The farming of wetland plants on rewetted peatlands offers potential compromises that allow for sustainable economic use while maintaining ecological function 3 .
Future conservation efforts must prioritize the large, intact peatland complexes that remain, while exploring restoration opportunities in degraded areas where feasible.
The story of Western Polissia's peatlands serves as a powerful reminder of the interconnectedness of local environmental changes and global climate systems.
What happens in these seemingly marginal wetlands halfway across Europe has consequences for us all through their impact on the planetary carbon cycle.
The protection and restoration of peatlands represents one of the most cost-effective and immediately beneficial strategies available in our fight against climate change and biodiversity loss.
