PAAUILO, Hawaii, May 9, 2013 /PRNewswire/ -- Hawaiian Legacy Hardwoods (HLH) today announced the planting of its 200,000(th) native koa tree on the Hamakua Coast of Hawaii Island, well on the way to its goal of 1.3 million trees. In three short years, more than 500 acres of former pastureland have been reclaimed as native forest. While koa is the backbone of the forest, HLH has gone beyond, working to develop an entire native ecosystem. In addition to koa, HLH is planting many...
United States Geological Survey While the iconic Haleakalā silversword plant made a strong recovery from early 20th-century threats, it has now entered a period of substantial climate-related decline. New research published this week warns that global warming may have severe consequences for the silversword in its native habitat. Known for its striking rosette, the silversword grows for 20-90 years before the single reproductive event at the end of its life, at which time it produces a...
April Flowers for redOrbit.com - Your Universe Online About 50 miles underground, there is a deep connection between two of Earth's most notable volcanoes, Hawaii's Mauna Loa and Kilauea, that could explain some of their enigmatic behavior. A new study, led by Rice University, is the first to model paired volcano interactions. It explains how a link in Earth's upper mantle could account for the competition between Kiluea and Mauna Loa for the same deep magma supply. The results of this...
Brett Smith for redOrbit.com Sadly, the sudden death of the giant tortoise Lonesome George on the Galapagos Islands this Sunday marks the loss of another subspecies from the face of the Earth. When scientists first met Lonesome George on Pinta Island in 1972, they had thought his species, Geochelone nigra abingdoni, was already extinct. He was immediately placed into the park service’s tortoise breeding program on Santa Cruz Island and while he did mate with a female tortoise — the...
Lee Rannals for RedOrbit.com Mars Express has helped to unveil volcanic history of the Red Planet, providing more insight as to what lies underneath our celestial neighbor. The spacecraft has been floating above Mars, mapping out the planet, for five years, during which it has helped researchers find that lava grew denser over time, and that the thickness of the planet's rigid outer layers varies across the Tharsis region. The measurements were taken while Mars Express was orbiting...
An airborne radar developed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., has returned to Hawaii to continue its study of Kilauea volcano, Hawaii's current most active volcano. The Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, mounted in a pod under NASA's G-III research aircraft from NASA's Dryden Flight Research Center, Edwards, Calif., returned to Hawaii's Big Island on Jan. 7. The one-week airborne campaign will help scientists better understand processes...
Lava fingerprinting reveals differences between Hawaii's twin volcanoes Hawaii's main volcano chains--the Loa and Kea trends--have distinct sources of magma and unique plumbing systems connecting them to the Earth’s deep mantle, according to UBC research published this week in Nature Geoscience, in conjunction with researchers at the universities of Hawaii and Massachusetts. This study is the first to conclusively relate geochemical differences in surface lava rocks from both chains...
Orcus Patera is an enigmatic elliptical depression near Mars's equator, in the eastern hemisphere of the planet. Located between the volcanoes of Elysium Mons and Olympus Mons, its formation remains a mystery. Often overlooked, this well-defined depression extends approximately 380 km by 140 km in a NNE"“SSW direction. It has a rim that rises up to 1800 m above the surrounding plains, while the floor of the depression lies 400"“600 m below the surroundings. The term "˜patera' is...
Boulders deposited by an ancient glacier that once covered the summit of Mauna Kea on the island of Hawaii have provided more evidence of the extraordinary power and reach of global change, particularly the slowdown of a North Atlantic Ocean current system that could happen again and continues to be a concern to climate scientists.A new study has found geochemical clues near the summit of Mauna Kea that tell a story of ancient glacier formation, the influence of the most recent ice age,...
They went looking for lava tubes on Mars "” and found what may be a hole in the roof of a Martian cave.The 16 students in Dennis Mitchell's 7th-grade science class at Evergreen Middle School in Cottonwood, California, chose to study lava tubes, a common volcanic feature on Earth and Mars. It was their class project for the Mars Student Imaging Program (MSIP), a component of ASU's Mars Education Program, which is run out of the Mars Space Flight Facility on the Tempe campus.The imaging...

Haleakalā National Park is located in Hawaii in the United States, on the island of Maui. The park contains 33,265 acres of protected land, with 19,270 acres of designated wilderness. The area was initially added to Hawaii National Park in 1916, alongside the Kilauea and Mauna Loa volcanoes on the island of Hawaii. The creation of Hawaii Volcanoes National Park in 1961 helped established Haleakalā National Park and in 2000, the name of the park was altered to its Hawaiian spelling by the...
The National Park of American Samoa is located in the American territory known as American Samoa. The park is actually divided into three different areas comprised of the islands of Ta‘ū, Tutuila, and Ofu-Olosega. This park was legally established by Public Law 100-571 in 1988, but the land could not be acquired due to the traditional communal land system of its native inhabitants. However, in 1993, the National Park Service signed a fifty-year lease with Samoan village councils to acquire...
Olympus Mons -- Olympus Mons is the tallest mountain in the solar system, at 25 km. Located on Mars, and officially called by its Latin name Olympus Mons. It is named for the mountain on Earth. Olympus Mons is an apparently extinct shield volcano, the result of highly fluid magma flowing out of volcanic vents over a long period of time, and is much wider than it is tall; the average slope of Olympus Mons' flanks is very gradual. The Hawaiian islands are an example of similar shield...
