🌱 The Emerald Citadel: Life on the Expanded Dokdo

In our previous post, we imagined a Dokdo with twice the surface area—a massive "fortress" of rock and plateau. Today, we explore the biological consequences. If humans never set foot on this island, what would live there?

Staying grounded in realistic science, here is the speculative biology of the 2x Dokdo.

1. The Green Core: Beyond Salt-Tolerant Grass

Currently, Dokdo's vegetation is dominated by hardy, salt-tolerant plants like sedum and aster. In a 2x scenario, the "Inland Buffer Zone" changes everything.

• Shrub Forests: With a wider plateau on Seodo, the center of the island would be far enough from the coast to escape the constant "salt rain" of sea spray. This would allow for the growth of denser shrubbery and even small, wind-resistant trees like the Japanese Spindle tree (Euonymus japonicus) to form thickets.

• Soil Accumulation: A larger, flatter surface means less soil is washed away by rain. Thicker soil layers would support deeper-rooted plants, turning the island from a "speck of green" into a "lush emerald canopy."

2. The Sky Dwellers: A High-Density Avian Sanctuary

For birds, land area is prime real estate. Doubling the size doesn't just double the population; it creates a more complex hierarchy.

• Expanded Nesting Colonies: The Swinhoe’s Storm-petrels and Streaked Shearwaters would establish massive, permanent colonies. The increased interior space protected by cliffs would provide a safer haven from predators and harsh winds.

• The Raptor’s Watch: While the Peregrine Falcon already visits Dokdo, a 2x landmass with more stable prey (smaller birds and insects) might support a permanent resident pair, making them the apex predators of the island's skies.

3. The True Kings: A Paradise for the 'Gangchi'

The most significant change would be for marine mammals. In the 19th century, the Japanese Sea Lion (Gangchi) thrived here. On a 2x Dokdo, their presence would be legendary.

• Massive Wave-cut Platforms: As discussed in the geology post, the expanded rocky shelves would provide hundreds of square meters of flat "lounging" space. This would allow for a much larger breeding colony of Sea Lions and potentially Northern Fur Seals.

• Safe Nurseries: The deeper inlets and wider rock pools would serve as perfect, wave-protected nurseries for pups, ensuring a much higher survival rate for the species.

4. The Tiny Pioneers: Insects and Invertebrates

Will there be land mammals like deer or rabbits? Realistically, no. The $210\text{km}$ distance from the mainland is an impassable barrier for non-flying mammals.

• Invertebrate Diversity: However, more stable soil and diverse plants mean more insects. We would likely see a higher variety of beetles, spiders, and perhaps even land snails that arrived via "hitchhiking" on bird feathers or drifting wood.

• The Freshwater Myth: While a 2x Dokdo might have a small "seepage" or a marshy basin on Dongdo after rain, it is unlikely to form a permanent lake. Life would still revolve around the rhythm of the rain.

Conclusion: A Heavy Silence

Without human interference, the 2x Dokdo would not be a "Jurassic Park" of monsters, but a louder, greener, and more crowded sanctuary. It would be a place where the air is thick with the scent of shrubs and the deafening calls of thousands of birds—a true masterpiece of isolation.
