Slope and soil regeneration at Walkers Reserve addressed steep quarry slopes and erosion
Landform stabilisation and soil reconstruction laid the foundations for ecological recovery through integrated earthworks and contour systems, including terraces, swales, and berms, combined with vegetation-based stabilisation. These now regulate runoff, improve water infiltration, and support vegetation across the site.
Challenge
The site consisted of steep, unstable quarry slopes (20–90%) with severe erosion, gullies, exposed substrates, and degraded soils, resulting in poor water infiltration, high runoff, and limited vegetation establishment
Solution
Integrated earthworks and hydrological design including slope regrading, contour systems (terraces, swales, berms, ponds), and vegetation-based stabilisation regulate water flow, rebuild soils, and stabilise slopes
Outcome
The interventions reduced erosion, restored soil and hydrological function, and enabled vegetation establishment, creating conditions for biodiversity recovery and the regeneration of a previously degraded landscape

Post-Quarry Landscape
Walkers Reserve occupies a former coastal sand quarry defined by steep slopes, exposed sand and clay substrates, and highly variable terrain. These conditions drive complex drainage patterns, erosion processes, and soil formation across the site.
After sand extraction the landscape’s foundation was highly destabilised. Soil and slope stabilisation efforts are ongoing early landscape regeneration activities that create the physical foundation for native species plantings and long term landscape restoration.

Erosion Control
Slope stabilisation was achieved through integrated earthworks and hydrological design. Slopes were regraded and contour systems, including terraces, swales, berms, ponds, and boomerang earthworks, were implemented to slow runoff, increase infiltration, and regulate water.
Vegetation-based stabilisation using vetiver grass, soil-binding species, and nitrogen-fixing pioneer species restored degraded substrates and improved moisture retention and root penetration. Over 20 km of vetiver grass has been planted across Walkers Reserve’s steep landscape.

Storm Resilience
The slope stabilisation efforts at Walkers Reserve have endured nearly a decade of Barbados' most severe seasonal weather, from Tropical Storms Harvey, Kirk, and Gonzalo's heavy rainfall and sustained winds to Hurricane Elsa's roof-tearing gusts, the first hurricane to severely impact the island in 65 years.
Most recently, they withstood Hurricane Beryl's powerful coastal storm surge in 2024, underscoring how well these interventions hold up under intensifying seasonal conditions.

Slope Recovery
These slope stabilising interventions are transforming unstable post-industrial terrain into a stable, biodiverse landscape. The integrated systems protect steep slopes and wetland edges while building the structural and soil conditions required for long-term habitat resilience.
The landscape now functions as an interconnected ridge-to-reef landscape linking coastal, wetland, forest, and agroforestry systems. This enables the development of diverse microhabitats which have resulted in the return of pollinators, birds, and small mammals.
