Between August and September, tadpoles will metamorphose into juvenile frogs. Diet Carpenter frogs eat a majority of aquatic insects and invertebrates such as small crickets, bug larva, and spiders. Threats One of the main reasons that the carpenter frog has become of special concern is due to its susceptibility to habitat loss and degradation. In the 1990s the carpenter frog population in Talbot County was found to be severely decreased as a possible result of habitat degradation. (Given, 1999; White and White, 2002) In South Georgia the Carpenter Frog is considered a common species although it has a limited range. Considering that the Carpenter Frog requires wetland areas with large amounts of submerged vegetation for breeding, human disturbances, such as ditching and urbanization, to such environments have and will continue to impact the species. ("Conservation Plans for Biotic Regions in Florida Containing Multiple Rare or Declining Wildlife Taxa", 2003) Because it is known to thrive in acidic waters, throughout time the neutralization of water, specifically in the Delmarva region, has had a great impact on its decline in population because they are unable to adapt. As wetlands become less acidic, it becomes a new habitat for a larger variety of frogs and other species that can thrive in these conditions. It is suggested that predation also plays a role in the decline of their population. These larger frogs include more aggressive species such as northern green frogs which can potentially be a great threat to the carpenter frog. The presence of American Bullfrogs (Lithobates catesbeianus) and Pig Frogs (Lithobates grylio) have also negatively affected the species. Apart from other frogs becoming a threat to the carpenter frog, some research suggests that water snakes (Nerodia) also prey on the carpenter frog. References Baker, Christina.
