Strengthening the conservation value of ex situ tree collections

“The Ex Situ Conservation of Stinking Cedar”

The propagation of plants for food, timber, medicines and aesthetics has been a principal activity of man for millennia. However, the systematic propagation of plant material for the purposes of conservation has a recent history, probably dating back only a few decades. The propagation and distribution of Torreya taxifolia from wild collected, documented material is one of the largest projects ...

Integrating Ex situ and In situ Conservation of Lemurs

Site-based and cross-regional habitat and species conservation e!orts in Madagascar, such as proposed in the previous chapters of this Lemur Conservation Strategy, should always be the main focus of lemur conservation. However, with many wild lemur populations rapidly declining and their habitat being lost at constantly high rates, captive assurance colonies are becoming increasingly important,...

Sampling for Effective Ex Situ Plant Conservation

Integrating In-Situ and Ex-Situ Data Management Processes for Biodiversity Conservation

There is an increasing need for a “one plan approach” for conservation strategies that integrate in-situ and ex-situ management processes. Zoological institutions contribute directly to threatened species conservation through paradigms, such as reintroduction, head-starting, supplementation, or rescue/rehabilitation/release. This in-situ/ex-situ integration necessitates collaboration at all lev...

Tools for the ex situ conservation of the threatened species, Cycladenia humilis var. jonesii

Ex situ conservation is critical for hedging against the loss of plant diversity. For those species (exceptional species) that cannot be conserved long-term in standard seed banks, alternative methods are required, often involving in vitro culture and cryopreservation, or storage in liquid nitrogen. Cycladenia humilis var. jonesii is a federally threatened perennial native to Utah and Arizona. ...
