Forest stand affected by Ceratocystis wilt. Extent The disease affects non-contiguous forest stands ranging from 1 to 100 acres.
Symptoms Crowns of affected trees turn yellowish (chlorotic) and subsequently brown within days to weeks; dead leaves typically remain on branches for some time (Figure 1). Symptoms of Ceratocystis wilt of ʻōhiʻa include rapid browning of affected tree crowns. Figure 1. Free Resources - Forest Starr & Kim Starr - Starr Environmental. Silverswords being coaxed back from near oblivion. Posted on: Monday, June 5, 2006 Silverswords being coaxed back from near oblivion By Christie WilsonAdvertiser Neighbor Island Editor Silverswords are making a comeback on the slopes of Mauna Loa and Mauna Kea after being reduced to near extinction by grazing animals.
Last winter marked a final full round of plantings of the Mauna Loa or Ka'u silversword, with 1,958 seedlings placed at three sites close to the Mauna Loa Trail by volunteers and Volcano Charter School students led by rare-plant specialist Ane Bakutis. Since 2000, nearly 13,340 plants propagated at the University of Hawai'i's Volcano Rare Plant Facility have been put into the ground at Hawai'i Volcanoes National Park, according to Rhonda Loh, acting chief of the park's Natural Resources Division. Visitors to the park already can see some of the plantings along hiking trails, and silverswords should become a more common sight in years to come. "They're like ice cream to sheep," Bakutis said.

Story by Janice Crowl Photos by Jack Wolford The sky above MacKenzie Park on the windward coast of Hawai‘i Island is cloudless; drought has plagued the island for weeks. Usually by October the park is a mushroom wonderland. Instead the duff of the ironwood forest floor is dry as shredded wheat. Nevertheless, the mushroom man is undeterred. “Try to imagine thousands of mushrooms right here!” Hemmes says that looking for mushrooms is like going on an Easter egg hunt— you never know what you’ll find. Hemmes often leads hunts at Mac- Kenzie, where most of the vegetation and fungi aren’t native to Hawai‘i. Uphill Hemmes finds dehydrated “earthstars,” mushrooms that have adapted to drier areas.
During the rainy season, MacKenzie Park is bursting with hundreds of unabashedly phallic “stinkhorns.” Young Naturalist Awards. PACSOA - Pritchardia beccariana. Figure 1.
