Case Study: Introduced Tree Species Devastating A Tropical Biological Hotspot

At first, the species took over land abandoned from the cultivation of coffee and tree crops, but more recently it has expanded into the natural forests of the Blue and John Crow Mountains National Park. This invasion was accelerated by the damage caused to the forests by Hurricane Gilbert 29 years ago, and it is likely to be further advanced by future major hurricanes. The National Park is a globally important hotspot of biodiversity with many rare and endangered species, including orchids, butterflies and birds, some of which are found nowhere else in the world except for the mountain forests of Jamaica. (Click on title for full story.)

Our Love For Orchids Will Be The Death Of Them. A Review Of Illegal Trade In Wild Species.

Orchids are one of the largest plant families and are commercially traded for a variety of purposes, including as ornamental plants, medicinal products and food. These markets involve thousands of species, which may be traded legally or illegally, sustainably or unsustainably, and take place at local, national or international scales. In this review, we provide the first overview of commercial orchid trade globally and highlight the main types that involve wild-collected plants. Much of this trade is the result of illegal harvest meaning that it is little documented and is absent from official statistics, at the same time as being of growing conservation concern.

Researchers Apply Microbes To Save Endangered Plant

Transplanting wild microbes from healthy related plants can make a native Hawaiian plant healthier and likelier to survive in wild according to new research. (Click on title for full story.)

When Is Enough, Enough? An Approach To Evaluate Alien Plant Invasions And Native Species Decline

Plants comprise the biggest and best-studied group of invasive species. There is a growing debate; however, regarding the nature of the alien plant threat—in particular whether the outcome is likely to be the widespread extinction of native plant species. The debate has raised questions on whether the threat posed by invasive plants to native plants has been overstated. We provide a conceptual framework to guide discussion on this topic, in which the threat posed by invasive plants is considered in the context of a progression from no impact through to extinction.

It Takes A Village With Some Self-Interest To Save A Rare And Endangered Tree In Vietnam

“The success of the project comes down to the trust and understanding we have developed with local people. By helping to establish local village nurseries, we have helped people to grow and replant a variety of trees that complement and add value to traditional ways of life.” (Click on title for full story.)

Saving Endangered Plants: Botanic Gardens Hold 41% Of All Endangered Plant Species

The world’s botanic gardens contain at least 30% of all known plant species, including 41% of all those classed as ‘threatened’, according to the most comprehensive analysis to date of diversity in ‘ex situ’ collections: those plants conserved outside natural habitats.  (Click on title for full story.)

North America’s Ubiquitous Ash Trees Declared Endangered

Five of the six most prominent ash tree species in North America enter The IUCN Red List as Critically Endangered – only one step from going extinct – with the sixth species assessed as Endangered. These species are being decimated by the invasive Emerald Ash Borer beetle(Agrilus planipennis). Three of them – Green Ash (Fraxinus pennsylvanica), White Ash (Fraxinus americana) and Black Ash (Fraxinus nigra) – are the country’s most dominant ash trees, comprising nearly nine billion trees in the forested lands of the contiguous U.S. (Click on title for full story.)

Reconsidering The Value Of Alien Plants When Native Ecosystems Are Too Degraded

“Conservation practitioners are investing millions of dollars to eradicate invasive species, but what if some of those invasive species are actually benefiting native species and ecosystem services? Our experimental study shows for the first time that this can be the case.” (Click on title for full story.)

Long Buried “Ghost Ponds” May Hide Extinct Plant Species

“Given the range of different seed types that we found capable of germination after 150-plus years, it could be reasonable to expect that ghost ponds could provide suitable reservoirs of rare or even extinct species,” (Click on title for full story.)

Is Every Endangered Plant Species Worth An All Out Conservation Effort?

One in five of the world’s plant species is threatened with extinction, according to the annual State of the World’s Plants report from Royal Botanic Gardens, Kew. That’s a lot of plants that need tender love and care – and money – to keep them from going extinct. (Click on title for full story.)
