Habitat clearance is threatening global biodiversity. In many places, isolated trees are all that remains of once extensive forest. So what happens to these trees and how can they survive in their new, highly modified environment without becoming the ‘living dead’?
The world’s most isolated tree, an acacia in Nigeria, used for decades as a marker by Tuareg traders and caravans, was recently knocked down by a drunk truck driver who thought it was a mirage
Why do we need to take urgent account of current climate maladaptation in ecological restoration…..

Forensic science has achieved infamy, thanks to television dramas like CSI. But it isn’t just about solving human crimes. Scientists are also using evidence from wood to help solve murders, but in this case the victims are the trees themselves, and the crime is illegal logging.

REDD+ (Reducing emissions from deforestation and forest degradation) is nothing new, but how exactly does it help reduce deforestation and green house gas emissions and will it be given a new lease of life through the Green Climate Fund (GCF).
The concept of REDD was extended with a ‘+’ to more specifically focus on the role of conservation, sustainable management of forests, and enhancement of forest carbon stocks in developing countries
Science can identify the source of timber and verifying legality. So it should be a simple case to apply the science to new international legislation that aims to limit illegally logged timber in global supply chains. Well not quite, the application of science requires understanding of the timber industry and supply chain dynamics. A new paper helps identify how science can help eliminate illegal logging.
Artists impression of illegal timber in supply chains. The image plays on the idea of identification by arranging logs into a visual barcode – DNA barcoding is also a method of species identification. A single red log dripping blood depicts the environmental and societal damage caused by illegal logging and the fingerprints highlight our ability to now identify these types of products in global supply chains (attribution: Little Bones and the Environment Institute) .
Roof top gardens aren’t just a quasi hipster architect’s dream concept, but really help insulate and cool buildings, capture rainwater and provide locally sourced food. Scientists are now extending their uses to help conserve endangered plant species.

A global movement is underway to design and live in ecovillages, but what are they and what can they offer?

The fertile crescent is the birth place of modern agriculture, where humans changed from shifting nomads to become settled farmers. But in a world where biodiversity is being lost, how do we conserve the future adaptability of crops from this region, and others, to ensure we can keep feeding the world?

There has been a recent recommendation to set restoration baselines as pre-degradation ecological communities. However this is a nostalgic aspiration, akin to restoring the ‘Garden of Eden’. It is unrealistic, expensive and does not acknowledge ecosystem change. Restoration should respond to the current drivers of biodiversity loss by addressing declines in ecosystem function and provisioning of ecosystem services.

You are probably unintentionally contributing to the future demise of the Siberian tiger. Tiger habitat, predominantly Mongolian oak, is being destroyed by illegal logging. As consumers of oak furniture, which has potentially been illegally sourced from tiger habitat, we are all part of the problem, but we can also be part of the solution. The next time you buy solid oak furniture, ask where it comes from?
