Vernal Pool definition

Vernal Pool means, pursuant to R.I. Gen. Laws § 2-1-20(17), a depressional wetland basin that typically goes dry in most years and may contain inlets or outlets, typically of intermittent flow. Vernal pools range in both size and depth depending upon landscape position and parent materials. Vernal pools usually support one or more of the following obligate indicator species: wood frog (Lithobates sylvaticus), spotted salamander (Ambystoma maculatum), marbled salamander (Ambystoma opacum), and fairy shrimp (Eubranchipus spp.) and typically precludes sustainable populations of predatory fish.

Vernal Pool means a small, shallow depression in the landscape that tends to fill with water during spring and late fall and become drier during the summer months. It shall be natural and lack a permanent outlet or any fish population. Further, the occurrence of one or more of the obligatory species which include the fairy shrimp, spotted salamander, Jefferson salamander, marbled salamander, wood frog, and eastern spade foot toad is necessary to conclusively define the vernal pool.

Vernal Pool means a type of seasonal wetland habitat that is characterized by a specific set of physical parameters and a unique assemblage of highly specialized endemic plants and animals; a seasonal body of standing water that typically forms in the spring from direct precipitation, with occasional contributions from other sources, dries out completely in the hotter months of summer, and refills in the autumn; pools free of fish that provide important breeding habitat for many terrestrial or semi-aquatic species such as Branchiopods, frogs, and salamanders.
