Perch Creek Nature Trail & Preserve
Short description of the intervention
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).

Impacts, benefits
Description of environmental benefits
-Strengthened capacity to address climate hazards/natural disasters: "the project aims at [...] preserving the City of Mobile's remaining coastal wetlands." (Ref 1),"The wetlands also store stormwater and help control flooding, critical issues as storms grow in frequency and intensity" (Ref 3)
-Improved water quality: "the river and the bay acting as sponges to rising tides while slowing and cleansing urban stormwater" (ref 1), serves as a natural filter for runoff from adjacent roads and residential and commercial properties.” (Ref 3), " high quality water resources" (Ref 3)
-Increased protection against flooding: "role in flood control and tidal impacts" (Ref 1), "Preserving the natural function of these areas [...] keeping much needed flood and stormwater absorbing wetlands." (Ref 2)
-Improved stormwater management: "cleansing urban stormwater" (Ref 1), "The wetlands also store stormwater and help control flooding, critical issues as storms grow in frequency and intensity." (Ref 3)
-Enhanced protection and restoration of coastal and marine ecosystems: "wetlands and the natural ecosystems they provide, the area is alive with wildlife" (Ref 1), "The Perch Creek Preserve will protect critical fish and wildlife habitat, coastal streams, forests and brackish marsh that are all essential parts of our estuary". (ref 3)
-Increase in protected green space areas: "The Perch Creek Preserve will protect critical fish and wildlife habitat, coastal streams, forests and brackish marsh that are all essential parts of our estuary". (ref 3), "This project includes the acquisition of 31 acres" (Ref 1)
-Increased conservation or restoration of ecosystems: "The Perch Creek Preserve will protect critical fish and wildlife habitat, coastal streams, forests and brackish marsh that are all essential parts of our estuary". (ref 3)
-Increased ecological connectivity across regeneration sites and scales: "projects like this represent ‘the best of the best’ for conservation — [...] connectivity in wildlife corridors" (Ref 3)
-Reduced biodiversity loss: "the nursery grounds of Mobile Bay", "The area is rich in wildlife." (Ref 1)
-Increased presence and recovery of wild species: "Whether its tall shorebirds or tiny migrating hummingbirds making their way via the North American bird and butterfly migration routes, Red Fox or American Alligator, West Indian Manatee or Bald Eagle, they all find food and refuge among the quiet wetlands." (Ref 1)
-Improved prevention or control of invasive alien species: "The project includes [...] invasive species management" (Ref 2)
