Regenerative Agriculture

Walkers Reserve is a 277-acre landscape on Barbados’ east coast, where a former sand quarry is being transformed into a biodiverse coastal and inland ecosystem.

Walkers Reserve restoration broke ground in 2010. WIRRED has led the long-term restoration work of rebuilding soils, restoring water systems, and reconnecting fragmented habitats. The early site strategy drew on indigenous land-use knowledge and local organic growers, later supported by ecological consultants, researchers and regional partners.

The site is now open to the public, with guided tours, education programmes, and community events taking place across the reserve. Today, Walkers Reserve functions as a living laboratory for Caribbean biodiversity and a bioregional education hub, where regeneration, research, and learning happen within the landscape. It shows how degraded landscapes can be transformed into climate-resilient ecosystems that support both nature and people.

Challenge

A former sand quarry with unstable slopes, depleted soils, and disrupted water systems experienced erosion and sediment runoff into coastal and estuarine environments, while fragmented habitats limited biodiversity recovery

Solution

A long-term regeneration programme focused on restoring freshwater systems, rebuilding soils, reintroducing native coastal and wetland species, and expanding local conservation skills to reconnect ridge-to-reef ecosystems

Outcome

A regenerated 277-acre landscape supporting over 248 plant and fungal species, 135 animals, and 100 migratory birds, now functions as a connected mosaic of wetlands, dunes, forests, and agroforestry systems that strengthen biodiversity

Challenge

Solution

Outcome

Challenge

Low tree cover and degraded landscapes across Barbados reduce habitat quality, limit biodiversity, expand heat effects, and weaken landscape ecology benefits.

Solution

A nationwide tree planting initiative to plant one tree per citizen of Barbados, 285,000 trees, through native species restoration, local nursery operations, and community-led planting.

Outcome

Thousands of trees planted, increased public participation, restored habitats, and contributions to national climate and biodiversity goals.

Before

After

Walkers Reserve is now a replicable bioregional model for restoring degraded landscapes across the Caribbean.

Working with ecological consultants, local practitioners, and regional partners, WIRRED supported the gradual stabilisation of the site by reshaping slopes, rebuilding soils, planting native species, and restoring water systems to reduce erosion and downstream impacts on estuaries, dune systems, and coral reefs.

As the land slowly recovered, native and pioneer species were reintroduced to stitch coastal and inland habitats back together. Over time, biodiversity began to return, particularly the presence of native and migratory bird species, and the landscape became more connected and resilient from ridge to reef. The site evolved into a working field location, where restoration methods and ecological research are tested within the living landscape.

Under WIRRED stewardship, Walkers Reserve has hosted site visits, learning programmes and field-based education that brings students, academics, practitioners, and communities into contact with ongoing land regeneration work. Micro-enterprises, like the Apiary and food markets, have grown into replicable models of community-led livelihood, equipping local participants with the skills, training, and market access to build income-generating ventures rooted in the reserve's ongoing regeneration work.

As climate pressures like stronger storms increase across the Caribbean, Walkers Reserve demonstrates how degraded land can be transformed into biodiverse ecosystems that support ecological recovery, climate resilience, and human wellbeing.

Walkers Reserve Regeneration Projects

WIRRED implemented regeneration projects to stabilise the landscape, restore habitats, and enable long-term ecological recovery through water systems, native vegetation, coastal restoration, and regenerative agriculture.

Slope & Soil Regeneration

Steep quarry slopes were stabilised through earthworks, contouring, and vegetation to control runoff, rebuild soils, and support long-term recovery.

Freshwater Systems & Hydrology

Walkers Reserve integrates lakes, wetlands, and channels to manage rainfall, reduce erosion, and improve water quality and biodiversity.

Habitat Regeneration

Habitat regeneration re-established interconnected wetlands, forests, dunes, and coastal habitats, guided by mapping and biodiversity assessments.

Regenerative Agriculture

Permaculture orchards, syntropic systems, and chinampa-style cultivation produce tropical crops for climate-resilient food production.

Coastal Ecosystem Restoration

Walkers Reserve restores dunes, mangroves, estuaries, and coastal forests to rebuild land-sea resilience, restore habitat, and stabilise shorelines.

Coastal Forests
& Woodlands

Native vegetation, including coconut groves and seaside mahoe, helps reconnect habitats, strengthen soils, and support long-term carbon storage across coastal dry forest and woodland systems.

Dunes

The dune system has been stabilised through native planting across foredunes, embryo dunes, and backdunes, providing shelter and nesting conditions for coastal species while stabilising the shoreline.

Shrubland

Dense coastal shrubs have returned across the site, creating sheltered habitats for insects, birds, and reptiles. These areas also help stabilise soils and link coastal and inland ecosystems.

Mangroves &
Estuarine Wetlands

White and red mangroves and estuarine wetlands now form an ecologically active zone on the site. Mangroves slow water movement, trap sediment, and provide habitat for fish, crabs, and migratory birds.

Targeted interventions, including microhabitats, nesting structures, and engineered wetlands, create healthy conditions for shoreline and aquatic species. Ongoing monitoring through BirdNET and field surveys has recorded over 100 species, tracking how populations and habitat use are changing over time. Over time, nesting success has strengthened and migratory activity has become more consistent across the site.
