Plant Health Protocols for the Reintroduction of Native Plants

Many botanic gardens and conservation agencies are now cultivating threatened native species specifically for reintroduction programmes in response to the second part of Target 8 of the Global Strategy for Plant Conservation (GSPC). While collection, cultivation and reintroduction techniques are frequently discussed in workshops and described in papers, few seem to have considered the threats of introducing non-native pests, diseases, weeds and hybrids between different populations of the same species. The Royal Botanic Garden Edinburgh has been cultivating plants for its Target 8 programme since 2005 and now grows 82 per cent threatened Scottish species. It is running active reintroduction programmes for nine of these species with programmes planned for a further five species. In recent years increasing attention has been paid to reducing the risks of introducing non-native organisms and hybrids between different populations of native species into the wild.This paper describes the protocols that have been developed, including verification, screening for pests and diseases, averting spontaneous hybridisation and preparing plants for reintroduction

Starting a conservation collection of Sorbus pseudomeinichii

There are three endemic Sorbus species on the Isle of Arran in Scotland: Sorbus arranensis, S. pseudofennica and S. pseudomeinichii. The latter is the most recently discovered and is represented in the wild by a single individual. Seed propagation and vegetative propagation by chip budding were initiated for all three species at the Royal Botanic Garden Edinburgh (RBGE). This has been successful and there are now conservation collections of these species growing at RBGE

Data Capture Project at the Royal Botanic Garden Edinburgh

Botanic gardens, with their large holdings of living plants collected from around the world, are important guardians of plant biodiversity, but acquiring and curating these genetic resources is enormously expensive. For these reasons it is crucial that botanic gardens document and curate their collections in order to gain the greatest benefit from the plants in their care. Great priority is given to making detailed field notes and the process of documentation is often continued during the plants formative years when being propagated. However, for the large majority of plants this process often stops once the material is planted in its final garden location. The Data Capture Project at the Royal Botanic Garden Edinburgh is an attempt to document specific aspects of the plant collections so that the information captured can be of use to the research community even after the plants have died

Plant Collecting for the Ecological Garden and the Scottish Heath Garden at the Royal Botanic Garden Edinburgh

The Ecological and Heath Gardens at the Royal Botanic Garden Edinburgh were created in 1991 and 1997 respectively. The Ecological Garden started as a naturalistic area of native woodland plants where cryptogams were encouraged to grow. Building on its success other habitat types were created nearby. The Heath Garden replaced an older heather garden and sought to recreate the ‘feel’ of a Scottish upland heathland. In recent years additional wild origin material of conservation concern has been added to each Garden and this paper describes the process along with some of the plants selected
