Short Summary

This study evaluates the hydrological impacts of beaver reintroduction on a peatland system in Northwest Midlands Meres and Mosses, demonstrating that beaver-induced modifications increase peatland water retention and resilience to drought.

Objective

• Investigate the effects of beaver reintroduction on surface-groundwater interactions in a peatland ecosystem

Study Configuration

• Spatial Scale: Local (4.5 ha enclosure) with regional implications
• Temporal Scale: Four-year monitoring period, including a drought event

Methodology and Data

• Models used: None specified
• Data sources: Field measurements of surface water and groundwater levels, monitored over four years

Main Results

• Mean surface water and groundwater levels within the beaver enclosure increased more than fourfold and 37-fold, respectively, relative to control sites
• Significant reductions in WT variability over time in the beaver enclosure
• Enhanced water storage associated with beaver dams buffered WT decline during drought conditions
• Delayed onset of drought effects, shorter surface-water drought duration, reduced groundwater drawdown, and more gradual rates of WT decline and recovery in the beaver enclosure compared to control sites

Contributions

• Provides empirical evidence that beaver reintroduction can significantly modify peatland hydrological processes, enhancing WT stability under both baseline and drought conditions
• Offers insights into the role of ecosystem engineers in peatland hydrology

• Natural England (NE) project code: [Insert project code]
