Abstract: We reviewed the history and conservation of Sophora toromiro, a species that has been extinct in the wild since 1960 but has survived as scattered individuals in botanic gardens and private collections. The short‐term conservation of S. toromiro is dependent on the management of surviving ex situ stocks. This is being achieved through international collaboration by a working group established to coordinate the conservation management of the species. Molecular evidence indicates that… 

Ex situ conservation of threatened native plants in Finland: analysis of the current status.

The findings of this Finnish survey are similar to studies completed for botanic gardens elsewhere showing that there are deficiencies in intraspecific and within-population diversity, however, the accuracy of origin data and genetic intactness of the accessions were comparatively high.

Ex situ collections and their potential for the restoration of extinct plants

It is concluded that the recovery of plant species currently classed as extinct in the wild is not 100% successful and the possibility to achieve this should not be used as a justification for insufficient in situ conservation efforts.

Reintroduction of a dioecious aquatic macrophyte (Stratiotes aloides L.) regionally extinct in the wild. Interesting answers from genetics

Genetic analysis showed that reinforcement with female individuals from other European populations to increase the genetic diversity of the Italian female population is not necessary, and surprisingly, the geographically closest male population to the Po basin is not the best option for male reintroduction.

Plant Conservation and Botanic Gardens

With a history dating back to the sixteenth century, modern botanic gardens have had an important role in plant conservation, most notably since the second half of the twentieth century. The

New Zealand collections of Rhododendron as a resource for ex situ conservation

Rhododendron L. collections in New Zealand are used to analyse the contribution of introduced species in cultivation to global ex situ conservation, and the method used is proposed as a component of an ex situ Conservation strategy for New Zealand.

Determining Success Criteria for Reintroductions of Threatened Long-Lived Plants

Increasingly, species reintroductions are being attempted to counteract the loss of biodiversity worldwide. Plant reintroductions aim to create or maintain selfsustaining populations capable of

Horticultural plant use as a so‐far neglected pillar of ex situ conservation

We demonstrate how native and nonnative plant taxa used as ornamentals in private and public urban green spaces can significantly strengthen plant conservation in time of extinctions by expanding the

The genetic status and conservation management of two cultivated bulb species extinct in the wild: Tecophilaea cyanocrocus (Chile) and Tulipa sprengeri (Turkey)

This study revealed different geneticstructures for the two bulb species, Tecophilaea cyanocrocus and Tulipasprengeri, and the management of these species is needed to ensure their continued survival in cultivation.

Genetic diversity and pedigree for Sophora toromiro (Leguminosae): a tree extinct in the wild

The genetic diversity of the surviving stocks and herbarium samples has been assessed by means of random amplified polymorphic DNA (RAPD) and inter‐simple sequence repeat (inter‐SSR) analysis and indicated low levels of genetic diversity suggesting a very small number of founders.

On the Use of Surrogate Species in Conservation Biology

Surrogate species need to be used with greater care if they are to remain useful in conservation biology and both the goals and criteria of different surrogate classes differ substantially, indicating they should not be conflated.

No isozyme variation was detected after examination of the electrophoretic patterns of 22 putative loci in more than 150 plants in Lysimachia minoricensis, probably due to the shortage of sample propagules originally recovered in the field before its extinction.
