Redback salamander
Some scientists have reported that Redback salamanders are New Hampshire’s most abundant forest vertebrate in terms of overall biomass in the forest (weight of all redback salamanders combined greater than any other species). If you turn over a number of rotting logs in moist woodlands there’s a good chance you will find a redback salamander. Always make sure to replace logs in the position that they were first found. ©Mike Marchand photo
