Data and Modelling

Mapping connectivity for species and habitats across Sussex, so we can start to answer the complex question, what is a wildlife corridor?

Habitat Connectivity Modelling

Habitat connectivity describes how easily species can travel between the places they need for feeding, breeding, and shelter. Fragmented landscapes result in isolated populations, declining biodiversity, and weaker ecosystem resilience. Through improved connectivity, we can restore functional ecological networks, helping wildlife to move, thrive, and adapt to environmental change.

We are mapping habitat connectivity across the Weald to Waves corridor and the rest of Sussex, using five “Champion Species” that represent the needs of a wide range of wildlife. This approach enables us to plan and deliver habitat creation and restoration that supports biodiversity recovery and a connected, healthy landscape.

Project Aims

Identify areas of habitat fragmentation
Direct habitat creation and restoration efforts in the corridor
Identify potential areas for green infrastructure to improve connectivity
Highlight opportunities to link the urban environment with the farmed landscape

From the Eyes of Wildlife

Our Habitat Connectivity Modelling uses modelling techniques to map and understand how wildlife moves across Sussex. By combining land use data, the movement behaviour of our “Champion Species”, and pressures such as light pollution and roads, we can pinpoint areas where habitat fragmentation is limiting wildlife movement.

The Science Behind the Maps

Connectivity Pathways

Habitat connectivity modelling, bats

Connectivity pathways are identified using land cover data. By mapping how permeable different habitats and land uses are for a range of species,  we can predict movement pathways across the wider landscape.

Bottlenecks

Bottlenecks are identified using behavioural information, where species movement is limited to small corridors due to habitat fragmentation, potentially causing population isolation.

A Collaborative Effort

The success of these projects has been thanks to our amazing partners, who have contributed their expertise and resources to the scheme. Without them, nature recovery on a landscape scale would not be possible.
