Abstract

The Registrars of the International Oak Society are responsible for registering, updating, and locating new selections of oaks throughout the world. The majority of these come from North America and Europe. New cultivars are selected for a variety of reasons, including fall color, unique foliage, habit, form, and fruiting characteristics. These cultivars come to us in many ways. Although some are sent to us by their originators through the registration link on the IOS website, most must be tracked down individually via the Internet, nursery catalogs, various publications, and data from collections. In many cases, this work requires traveling to gather information from breeders, nurserymen, or collection holders, and to collect the Standard Specimens. The Registrars welcome information about new cultivars or older cultivars that have not been registered yet. Please send information either to Eike Jablonski (Eurasia, Australasia, and Africa) or Ryan Russell (the Americas), or visit www.internationaloaksociety.org/content/cultivar-registration.

Our results show that the Fagaceae diversity of the forests in our study area is unique in Taiwan. We conclude that it is necessary to create a conservation area in order to protect these forests and appeal for the support of Fagaceae lovers worldwide.
