Queen Sirikit Botanic Garden (QSBG) was established in 1994 to celebrate the 60th birthday anniversary of Her Majesty the Queen of Thailand. The garden is located in Chiang Mai province, northern Thailand. The garden area is about 1,000 hectares, of which approximately 70 percent covered by natural forest and 30 percent developed to be gardens, display glasshouses and other facilities. The main aims of the garden are to strengthening research and conservation of Thai flora, and to raise awareness of biodiversity and environmental conservation, as well as to provide an aesthetic place for the general public. More than 33,000 plants of 17,000 accessions representing 4,017 living plant taxa are maintaining to support the garden mission. Native orchids, gingers, medicinal plants, and threatened plant of Thailand are the highlight plant groups.The arboretum occupies most of the garden area, representing 593 tree species. Fabaceae, dipterocarpaceae, annonaceae, moraceaeare, and magnoliaceae the major tree collection.

QSBG displays a variety of designed gardens and glasshouses as well as natural science museum showcasing the diversity of plant along with interpretation for visitors to learn and enjoin of nature. The education programs on various kind of to topic related to plant and biodiversity are developed for a wide range of the audience. Herbarium, botanical library, insect museum, and other research facilities have been developed to support the research programs.

Founded in 2007 NUEBG is a private institution located in the province of Ilocos Norte, “Geared in conserving the plant diversity and the natural heritage of Northwestern Luzon, Philippines”. A biodiversity hotspot affected by annual tropical storms, and most of these that passes the Island Luzon are considered the strongest in the world. The NUEBG biodiversity research unit spearheads the exploration of its vegetation and monitoring 11 major ecological systems that are declared critical habitats and Key Biodiversity Areas (KBA). It is the leading institution in the northern Luzon in biodiversity study and recently published 8 new species to science since 2015.

The NUEBG established its systematic gardens including its arboretum and in situ conservation sites in 2007. These are extensively used for plant taxonomy/field botany and other related works like restoration ecology. NUEBG houses some of the world’s rare plant species including narrow endemics, conserved and in the course of propagation for future reintroduction. The NUEBG is considered the most diverse point in the northern Luzon with 2044 species represented by 227 families in its Systematic Collections, these collections are arranged in families following the latest in taxonomic treatment APG IV.

The Australian Botanic Garden is one of three botanic gardens operated by BGCP. Unlike our other two Garden’s (the Royal Botanic garden Sydney and the Blue Mountains Botanic Garden Mount Tomah) ABGMA is dedicated to displaying the native flora of Australia. Recently celebrating 30 years of the Garden’s original thematics. 

Australia’s largest botanic garden, ABMA has extensive areas of open grassland, native vegetation (including remnants of four endangered ecological communities), formal lawns and picnic areas, arboreta and approximately 30hectatres of intensive horticulture.  The core living or scientific collections are distributed between Arboretum plantings, five themed gardens and our key 4.7ha showcase, a snapshot of Australia’s biodiversity, called the Connections Garden.

The core arboretums collections focus is on Eucalypts, but other significant Arboreta include Wattles, Kurrajongs, Callitris and Figs. The core Eucalypt displays are split into sub genera collections including: Angophora, Corymbia, Eudesmia, Dyoblakea, Lataongulatea, Bisectae, Dumaria, Maidenaria, Adnataria, Sejunctae, Capillulus and Northocalyptus.

Most of the Theme Garden displays are situated under or adjacent to the canopy of remnant critically endangered Cumberland Plain Woodland species, such as; Eucalyptus tereticornis, E. moluccana and E. crebra, Brachychiton populneus, Actinostrobus but also consist of other native tree species which fall under the Taxa of: Acacia, Brachychiton, Casuarina, Araucaria and Banksia.

The San Diego Zoo Wildlife Alliance’s botanical collections are a lush, living treasure that enhance the wildlife experience while advancing global conservation efforts. Founded in 1916 and spanning over 1,900 acres between both the San Diego Zoo and Safari Park, these collections feature more than 2 million plants, including many rare and threatened species. From towering Champion thorn trees to endangered Hawaiian palms, the diverse array of plants is meticulously curated to inspire and educate visitors on the importance of plant biodiversity. As accredited botanical gardens and arboreta with robust conservation facilities, SDZWA contributes to scientific advancement and plant conservation on a global scale.

SDZWA is an active member in BGCI’s Global Conservation Consortia, with a special emphasis on our Species Stewards work with cycads (GCCC) and oaks (GCCO). Much of this work involves working with partner organizations to develop meta collections, in-situ population surveys and drive research in micropropagation and cryopreservation. Through the Beckman Center for Conservation Research they house a native plant gene bank, manage the Baja Rare program to work with the public and botanists across the border, and strive to preserve the critically endangered Torrey Pine.

The Royal Botanic Gardens is situated on 74 acres, hosting over 700 taxa and 3,500 individual trees. It contains extensive tree planting including many historic trees and pre-European settlement remnant trees. The organization also includes the National Herbarium of New South Wales, the premier reference collections of botanical specimens. The herbarium is used to study the classification, ecology, and evolution of plants in New South Wales, Australia, and the Pacific. The Australian Rainforest Garden is comprised of many rare and endangered tree and plants. The Palm Grove, established in 1862, represents one of the world's finest collections of pines. The Royal Botanic Gardens has developed educational and conservation programs. 

The Waugh Arboretum at UMass Amherst was founded in 1944 after the landscape architect pioneer Frank A. Waugh. His vision reflected the founding philosophy of the college that the land was more important than the buildings. The original plant introductions are credited to President William Clark who served as an agricultural advisor to Japan. Of the specimens brought over from Hokkaido includes the Japanese Elm – national champion and class tree of 1899 – which stands as the backbone of a strong Asian presence in the arboretum today. The Waugh serves as a living laboratory for Five-College and University research in landscape architecture, botany, horticulture, forestry, ecological restoration, and plant sciences and a resource center for external professionals such as landscape architects, nursery professionals, and amateur gardeners. Modern collection policies aim to invigorate campus sustainability standards and uphold this position as a top university in the fields of urban forestry, arboriculture, and landscape architecture.

The Arboretum is divided into three geographical parts, America (AAM), Asia (AAZ) and Europe (AEU), with trees, shrubs and ground cover composed of ca. 620 species from the respective regions.

The University of Puebla Botanic Garden (JB-BUAP) was started in 1986 and occupies a 10 ha site on the southern outskirts of the city of Puebla, southern Mexico. The Garden is well known internationally for its large collection of Mexican oaks, pines and other trees, many of them rare, as well as many other flowering plants. Within the oaks trees, they are growing 4 of the most restricted species in México and Q. “autopista”, one new species yet not described. Additonally, they have three species in our conservation collection: Q. brandegeii, Q. insignis and Q. hirtifolia.

Other collections include significant holding of species of Bursera and Jatropha, cacti and succulents, economic and ornamental plants and a good native flora including 5 native species of terrestrial orchids which grow in their grounds. It is committed to the documentation of the flora of the state of Puebla, and to the assessment of threatened tree species including propagating the rarer trees such as Pseudosmodingium barkleyi,  Fouquieria leonilae and Beaucarnea olsonii,  all recently discovered in Puebla.
