Recent estimates indicate that one-fifth of botanical species worldwide are considered at risk of becoming extinct in the wild.
Impacts of global climate change, habitat loss, and other environmental changes on the world's biota and peoples continue to increase, especially on islands and in high elevation areas.

The PCA Federal Committee, chaired by the Bureau of Land Management, developed the “National Seed Strategy for Rehabilitation and Restoration 2015-2020” in cooperation with Federal and non-Federal partners.
Although only a minority of plant species have a specific human use, many more play important roles in natural ecosystems and the services they provide, and rare species are more likely to have unusual traits that could be useful in the future.
The necessity to redesign and relandscape the interior of the Temperate Palmhouse at the Royal Botanic Garden Edinburgh (RBGE) created the opportunity to undertake a full curatorial survey of the palms and other plants contained in the Palmhouse.
In this paper, the case for the conservation of plants that have arisen in cultivation is provided and the mechanisms for extinction discussed, with examples.
