Conserving the Brandegee oak in Baja California Sur

Quercus brandegeei is an Endangered species of oak found only on the southern tip of Mexico’s Baja California peninsula. It grows in ephemeral stream beds that fill up after hurricanes and has very distinct, elongate acorns. Historically, ancestors to Quercus brandegeei were fairly widespread. Quercus brandegeei , however, is now confined to a very small range in Baja Sur. Moreover, the species’ future is severely threatened by lack of regen…

In the UK these factors do not pose a significant threat to our native trees but this does not mean we are immune from problems. This week is National Tree Week in the UK so what better time to learn about the threatened trees of Britain… In the UK there are around 15 threatened trees. The majority are endemic species o…

Global oak conservation partnership

Globally, oaks (from the genus Quercus) are of immense economic and ecological value. Oak timber and bark are used in a number of products (from whisky barrels to wine corks) and various species perform critical ecosystem functions; providing food and habitat for countless species of animals. However, many oak species are threatened with extinction and oak-dominated ecosystems are declining worldwide. Furthermore, oak acorns cannot be seed banke…

Ex situ conservation of exceptional species

There is currently no comprehensive resource to identify exceptional plant species, but this information is needed to help prioritize and focus  ex situ  conservation planning and activities. This project, led by BGCI US, is using information about seed storage behavior and data from the BGCI PlantSearch database to identify exceptional threatened taxa in the United States. BGCI U.S., working with partner botanic gardens and organizations across…
