Immature salamanders are amphibians in the order Caudata, which are characterized by their long bodies and tails. They are typically found in moist environments, such as near streams or ponds. The term 'immature salamanders' refers to young salamanders that have not yet reached adulthood. EFTS stands for 'Early-Life-Stage Temporary Shelters, ' which are structures that provide protection for these young salamanders while they are still developing.
