Abstract

The abundance, distribution, and viability of seeds of mamane (Sophora chrysophylla) were determined on study sites within the Mauna Kea Forest Reserve, island of Hawaii. An average of 42 to 305 seeds per m² were found to a depth of 4 cm. About two-thirds of them were on the soil surface or in the litter. More than 75 percent of the buried seeds were found in the first 2 cm of mineral soil. Over two-thirds of the sample quadrats yielded seeds at some sample depth. Twenty-three to 75 percent of the surface seeds and 18 to 68 percent of the buried seeds germinated.
