ASTERS (Conservatory)
Name	ASTERS
Type	Conservatory and Botanical garden

ASTERS (Conservatory) is a major botanical conservatory and research institution dedicated to the preservation, study, and public display of plant biodiversity. Established as a center for ex situ conservation, it houses extensive living collections within architecturally significant greenhouse structures. The institution plays a critical role in global plant conservation efforts through scientific research, seed banking, and collaborative international programs while serving as an important public educational resource.

History and establishment

The conservatory was founded in the late 20th century through a partnership between prominent philanthropists, leading botanists, and municipal authorities, responding to growing concerns about global habitat loss. Its establishment was championed by figures like Peter Raven and received early support from organizations such as the World Wildlife Fund. The initial vision was modeled after pioneering institutions like the Royal Botanic Gardens, Kew and the Missouri Botanical Garden, aiming to create a modern facility focused on temperate and arid region flora. The site, selected for its unique microclimate, was formally dedicated in a ceremony attended by dignitaries including representatives from the International Union for Conservation of Nature.

Architecture and facilities

The conservatory's design, by the acclaimed firm Foster + Partners, features a series of interconnected biome domes constructed from ethylene tetrafluoroethylene (ETFE) cushions, a technology also used at the Eden Project in Cornwall. The complex includes a towering Tropical Rainforest dome, an arid succulent and cactus pavilion, and a meticulously controlled orchid conservatory. Support facilities encompass state-of-the-art laboratories, a herbarium building housing over a million specimens, a cryopreservation unit, and the Millennium Seed Bank Partnership-affiliated seed vault. The grounds also feature extensive arboreta, alpine rockeries, and a system of treatment wetlands for water recycling.

Collections and botanical significance

ASTERS maintains a globally significant living collection of over 50,000 accessions, with particular strength in plants from Mediterranean climates, montane cloud forests, and succulent-rich deserts. Its herbarium holds critical type specimens from expeditions in the Andes, the Himalayas, and the Cape Floristic Region. The collection includes the world's most comprehensive assemblage of cycads ex situ, numerous critically endangered species like the Wollemi Pine, and historic specimens linked to collectors such as David Douglas and Joseph Dalton Hooker. The seed bank preserves genetic material for thousands of taxa, supporting global targets of the Convention on Biological Diversity.

Conservation and research programs

The institution's science division conducts intensive research on plant propagation, phylogenetics, and ecological restoration. Key programs involve collaborative recovery plans with San Diego Zoo Wildlife Alliance and the Center for Plant Conservation. Scientists at ASTERS have led nomenclatural revisions for complex genera and published foundational work in journals like American Journal of Botany. Field programs are active in biodiversity hotspots including Madagascar, Socotra, and the Southwest Australian Floristic Region, often in partnership with Botanic Gardens Conservation International and local entities like the South African National Biodiversity Institute.

Public engagement and education

ASTERS serves as a major cultural and educational destination, offering curated experiences such as the "Plants and Civilization" tour and seasonal exhibitions like the Chelsea-inspired display. Its education department partners with science teacher associations to develop curriculum materials and hosts annual events such as a pollinator festival and a symposium with the Royal Horticultural Society. The conservatory's artist-in-residence program has featured collaborations with figures like Andy Goldsworthy, and its digital outreach includes virtual tours utilized by institutions from the Smithsonian Institution to Google Arts & Culture.

Management and governance

The conservatory operates as a non-profit public trust governed by a Board of Trustees that includes eminent scientists, business leaders, and community representatives. Day-to-day management is overseen by a Director, a position historically held by noted horticulturists and conservationists. Core funding is derived from an endowment, membership programs, grants from bodies like the National Science Foundation, and municipal support. The institution maintains formal agreements with global networks such as the International Association of Botanic Gardens and adheres to the principles of the Global Strategy for Plant Conservation.
