Road Mortality is the main threat to many of the reptiles and amphibians found in LPWF, including the Blanding’s Turtle. Roads have also caused disruption of the natural hydrological functions of the Big Creek Marsh, one of the largest remaining coastal wetlands on the Canadian side of the Great Lakes.

Projects and public education campaigns are ongoing, such as the Long Point Causeway Improvement Project which began in 2006 and has installed several km of fencing and culverts to help reduce road mortality of significant species and restore hydrological connections between the Big Creek Marsh and Long Point Bay.
