Hiking Fifteen Billion

Jack Hartt's article "Hiking: Fifteen Billion" documents his enlightening hike along the Padilla Bay Shore Trail, where he encounters a massive invasion of Japanese mud snails. What began as a serene walk transformed into a shocking realization of the ecological crisis unfolding in the mudflats. Hartt learns from local experts that the snail population has surged to an estimated 15 billion, thanks to the absence of natural predators since their introduction in the 1920s. These invasive snails consume vital algae, threatening the survival of native species like crabs and birds. They also disrupt sediment layers, eroding the tidal flats.

Despite the invasive presence, Hartt appreciates the trail's beauty, filled with songbirds and spring warmth. This experience not only emphasizes the importance of awareness in preserving local environments but also highlights the ongoing challenges posed by invasive species. The article invites readers to reflect on the balance of nature and the impact of human intervention.
