Perch Creek is one of the many meanders that drain into Dog River (Ref 2), located just west of Mobile Bay (Ref 3). These areas include sensitive, tidally influenced marshes and flats where the brackish water of the Bay meets fresh waters (Ref 1). The Perch Creek Nature Trail & Preserve project aims to protect 96 acres on Perch Creek (Ref 3). It is part of efforts to revitalise Mobile’s coastal community and improve the water quality of the city's urban river (Ref 2), following the devastation of the BP oil disaster in 2010. The project focuses on two main aspects: creating a low-impact recreational destination to spark economic redevelopment, and preserving Mobile’s coastal wetlands (Ref 1). The conservation aspect involves wetland acquisition, marsh restoration, and invasive species management, improving water quality in both waterbodies (Ref 1). The area, rich in wildlife, requires habitat protection, including for migrating birds, foxes, alligators, manatees, and bald eagles (Ref 1). Brackish marshes on the property serve as nurseries for fish, while forested areas provide natural corridors for wildlife (Ref 3). The wetlands also play a role in flood control, acting as natural sponges to absorb rising tides and cleanse stormwater runoff before it reaches Mobile Bay (Ref 1). Additionally, they store stormwater, helping mitigate flooding as storms intensify (Ref 3). The recreational aspect includes developing nature-based recreation, such as nature trails and kayak launches, as well as expanding public access to natural resources (Ref 3). In 2018, the Perch Creek section was added to the Alabama Coastal Birding Trail, with educational signage for kayakers (Ref 1). This comprehensive project preserves vital habitats and flood-absorbing wetlands, while providing outdoor recreation opportunities and supporting the coastal community's recovery (Ref 2). It combines high-quality water resources, wildlife connectivity, scenic beauty, and outdoor recreation (Ref 3).

Key priorities
Focus
Project objectives
Implementation activities
Climate-focused activities
Climate change adaptation:
- Restore mangroves, marshes, reefs and wetlands to dissipate the effects of storms and floodwaters
- Implement sustainable urban drainage schemes to manage stormwater
- Restore rivers and other fresh water bodies to reduce flood or drought risk
- Restore and protect forests to prevent water runoff and assets loss due to flooding
Specification of climate or environmentally vulnerable communities
Biodiversity conservation or restoration-focused activities
Biodiversity restoration:
- Restore species (native, endangered, or unspecified)
- Clear and control invasive alien species
- Restore ecological connectivity
Main beneficiaries
- Local government/Municipality
- Citizens or community groups
- Coastal-dependent communities (e.g. small-scale fishers, coastal farmers, and indigenous peoples)
