Vegetation
Bokak supports just nine plant species. All are native to the Marshall Islands and entirely undisturbed by introduced species. A combination of insufficient rainfall, excellent drainage, and high temperatures lead to an arid environment in which a freshwater Ghyben-Herzberg lens cannot form, and Coconut Palm is unable to grow. The most common formation is a low, sparse scrub forest of Tree Heliotrope (Heliotropium foertherianum), 6–20 ft (1.8–6.1 m) tall, with occasional taller trees. The understory typically comprises Beach Naupaka (Scaevola taccada), or sparse endemic bunchgrass, ʻIhi (Portulaca molokiniensis), ʻIlima (Sida fallax), or Alena (Boerhavia herbstii), the latter being more abundant on broken coral gravel. A small stand of Pisonia grandis is found on Kamwome Islet and in another very small stand on Sibylla.
Pure stands of very dense Beach Naupaka shrubland, sometimes with Tree Heliotrope, are predominant and cover 50-75% of southern, and nearly 100% of northeastern Sibylla. Heliotropium, Scaevola, and Sida dominated shrublands and the sandy bunchgrass savanna (Lepturus spp.) represent the finest examples of such vegetation in the Marshalls and probably the entire Pacific region.
The aquatic vegetation of the shallow edges of the lagoon consists of sparse coralline algae, encrusting fragments of coral, shell etc., and patches of green sea weed.

Famous quotes containing the word vegetation:
“When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter ... decent weeds, at least, which widowed Nature wears.”
—Henry David Thoreau (1817–1862)
“We love to see any redness in the vegetation of the temperate zone. It is the color of colors. This plant speaks to our blood.... What a perfect maturity it arrives at! It is the emblem of a successful life concluded by a death not premature, which is an ornament to Nature. What if we were to mature as perfectly, root and branch, glowing in the midst of our decay, like the poke!”
—Henry David Thoreau (1817–1862)
“I would not have every man nor every part of a man cultivated, any more than I would have every acre of earth cultivated: part will be tillage, but the greater part will be meadow and forest, not only serving an immediate use, but preparing a mould against a distant future, by the annual decay of the vegetation which it supports.”
—Henry David Thoreau (1817–1862)
