“…Although a number of countries, such as Singapore and Colombia, have completed their National Red Lists for orchids (Yam et al, 2010;Calderon-Saenz, 2007), there is an urgent need to gather more data and to transfer more orchid species to the IUCN Global Red List. This would enable decisions to be made concerning those orchid species that are at most immediate risk of extinction in the wild, with the aim of bringing them into cultivation and banking their seeds.…”

Whilst there is overwhelming scientific evidence that dramatic changes in regional climates are likely to occur throughout the 21st century, the scientific community remains uncertain how the effects of global heating will combine with other environmental factors to affect wild orchid populations. It is, however, likely that many populations will be affected adversely and that in situ conservation techniques by themselves will not be sufficient to prevent the extinction of many species. A range of complimentary ex situ strategies are discussed.

“…A survey by Reiter et al () of 66 orchid species showed that reintroduction effectiveness ranged from 0 to 100% (66% on average for species monitored for at least 1 year), depending on different factors. At 8 years after the reintroduction of five orchids, Yam et al () obtained a similar range of survival (10–95% depending on species, seedling size, and microclimate characteristics, mainly moisture).…”

We carried out translocations of three rare plants that inhabit mineral islands in the marshy Biebrza Valley in order to create alternative populations and facilitate connectivity between existing subpopulations. The species chosen were Iris aphylla and two orchids: Cypripedium calceolus and Cephalanthera rubra. Thirty soil monoliths with vegetative orchid plants or parts of I. aphylla rhizomes were dug out and transplanted to three different sites on new mineral islands (half in 2012 and half in 2013). Prior to translocation, we measured soil moisture and pH and took phytosociological characteristics in 68 potential recipient sites for orchids and 15 for I. aphylla. Then, we monitored the number of shoots for 4 years and retrospectively conducted principal component analysis (PCA) in order to compare the similarity of donor sites and chosen recipient sites. Three years after transplantation we found new C. calceolus populations in good condition, I. aphylla populations in moderate, while C. rubra transplants emerged only in the first and second season. All newly established populations of C. calceolus and I. aphylla survived. In the case of the first species, fruiting was observed in two populations, while a marked increase in shoot number was observed in one population. The most successful C. calceolus translocation site was also the most similar to the donor sites according to PCA.

This study was carried out to investigate the range of distribution and vegetation structure of habitats of genus Cymbidium which is distributed in Jeju Island, Korea. This genus is distributed in tropical and subtropical Asia and North Australia. In Korea, there are six species [i. e. C. goeringii (Rchb. f.) Rchb. f., C. kanran Makino, C. lancifolium Blume var. aspdistrifolium (Fukuy.) S. S. Ying., C. macrorhizum Lindl., C. nagifolium Masam. and C. ensifolium L.], which were also distributed in Jeju Island. The habitats of this genus ranged between 16 meter and 574 meter above sea level in Jeju Island. C. macrorhizum had the broadest altitudinal range (16-574 meter above sea level), whereas C. ensifolium, C. nagifolium and C. lancifolium var. aspidistrifolium had the narrow altitudinal range. According to the classification analysis by TWINSPAN, the plant communities were divided into five groups of Castanopsis sieboldii community, Castanopsis sieboldii-Pinus thunbergii community, Pinus thunbergii-Quercus acutissima community, Pinus thunbergii community and Quercus glauca-Aphananthe aspera community. Three species, C. kanran, C. nagifolium, and C. ensifolium inhabited Castanopsis sieboldii community and C. lancifolium var. aspdistrifolium inhabited Castanopsis sieboldii-Pinus thunbergii community. C. macrorhizum inhabited Pinus thunbergii community, Pinus thunbergii-Quercus acutissima community and Quercus glauca-Aphananthe aspera community. C. goeringii inhabitated Castanopsis sieboldii-Pinus thunbergii community and Pinus thunbergii-Quercus acutissima community. The populations of the genus Cymbidium have been extremely decreased due to illegal collection in Jeju Island. Especially, the distribution range of C. kanran, C. nagifolium, and C. ensifolium was narrow and limited to evergreen broad-leaved forests, therefore, conservation plans are needed for the protection of these species.
