Plant Collections Network announces Standards of Excellence Project

Plant Collections Network is leading our public gardens community in developing standards of excellence for plant collections management. Our aim is to make these widely accessible and promote best practices throughout public gardens.

2016 Tree Collecting Grants awarded to five projects

Quercus dumosa

The Plant Collections Network is pleased to announce that five collaborative projects have been awarded funding this year through the Association’s Tree Gene Conservation Partnership with the US Forest Service. These scouting and collecting trips target the following threatened species in the wild: Quercus havardii and Magnolia pyramidata in South-Central states, Alectryon macrococcus var macrococcus in Hawaii, Trans-Pecos oaks in Texas, and Magnolia portoricensus in Puerto Rico. 

Fabaceae

The Fabaceae Collection of Boyce Thompson Arboretum has become the first primarily seed-based collection accredited by Plant Collections Network (formerly NAPCC). Also known as the Desert Legume Program, it began in 1988 as a joint project of the Arboretum and the University of Arizona. Its' internationally recognized seed bank of 1,454 taxa is housed at the university in Tucson, while 206 taxa are grown in field plantings and the Taylor Family Legume Garden at the Arboretum. Longtime curator Matthew Johnson has actively developed this collection since 1989.

Magnolia Multisite

The Magnolia Multisite collection comprises the National Collection of Magnolia and encompasses 17 member garden sites. Magnolia is a genus with a wide geographic range, including northern South America, Central America, North America, Cuba and parts of the Caribbean, China, India, Japan, South Korea and many other countries in southeast Asia and adjacent Pacific Islands east to Papua New Guinea.

Quercus Multisite

Oaks are among the most diverse and dominant trees in North America, so the genus Quercus was a natural choice for the first multi-institutional Plant Collections Network (formerly NAPCC) collection. After almost two years of planning and coordination on the part of Dennis Collins, Curator of Plant Collections at the Mount Auburn Cemetery, 15 gardens with large oak collections were inducted into the Plant Collections Network in August of 2007.
