Designates Aulacoseira newjerseyana as New Jersey State Diatom.

This bill designates the microscopic algae species *Aulacoseira newjerseyana* as the official state diatom of New Jersey. The legislation directly affects the state's symbolic recognition of aquatic life by formally naming this specific freshwater organism, which was discovered in 2022 in the state's Highlands ecoregion. The primary mechanism is a simple designation that adds this species to the state's list of official symbols, honoring its ecological importance and the scientists who identified it. No new laws, regulations, or funding are created; the bill serves solely to acknowledge the species' presence and significance within New Jersey's natural environment.
