This Week in Nature: The 4th week in August - Alula

What's Happening in Hawaii
during the 4th week in August:

Alula, or Brighamia insignis, is blossoming now on windward sea cliffs of Kaua'i and Moloka'i. Formerly found also on Maui and Ni'ihau, this rare and endangered native lobelia has made some remarkable adaptations to survive in its dry, windy, and salty environment.

In times of drought, alula lives on water it has stored in its thick stem and grows smaller leaves than usual, thereby reducing loss of moisture. its roots grow horizontally to provide footing in the thin soil and crevasses of cliff faces, and its base is rounded, enabling it to sway a little with the stiffest gusts of wind.

Owing to these adaptations, alula is a hardy and long-lived plant, with individuals reaching heights of more than twelve feet. Unfortunately, it now faces threats for which the centuries of evolution have not prepared it, including predation by goats, competition from foreign plants, and removal by admiring humans.

Brighamia insignis is one of the plants being monitored and protected by the Plant Extinction Prevention Program, or PEP.

New Plant Extinction Prevention (PEP) Poster

In order to promote understanding of rare, threatened and endangered plants in Hawaii, DOFAW outreach staff recently created a rare plant poster for the Plant Extinction Prevention (PEP) Program.

The Plant Extinction Prevention (PEP) Program’s mission is to protect Hawaii’s rarest native plants from extinction. PEP is committed to reverse the trend toward extinction by managing wild plants, collecting seeds and establishing new populations. PEP focuses on species that have fewer than 50 plants remaining, collaborating with conservation partners who have a shared interest in preserving Hawaii’s unique biodiversity.

If you'd like a copy of the poster, please leave a comment below. Supplies are limited.
