Scientists have presented an interesting method for measuring the success of ecological restoration. The basic concept of the habitat affinity approach is that it assesses the degree to which the species composition at a restoration site reflects that of the target habitat community......

"A common problem in conservation is that the wealth of experience and knowledge that practitioners gain over time is not well aggregated and shared." This is the sentiment that motivated Helen Rowe from Purdue University to interview 38 experienced tallgrass prairie managers about what they have learned from conducting ecosystem restoration on their preserves......

A recent observational study in northern Spain reveals that making a dinner reservation is important even for diners at a vulture restaurant.
As a sanitary disposal area of animal carcases, vulture restaurants provide a dual purpose of preventing contagious diseases such as bovine spongiform encephalopathy while serving as feeding stations for scavenging bird species that might otherwise be declining due to habitat loss.
However, these feeding stations do not mirror traditional patterns of carcasses found in the scavengers’ traditional habitats and may be favoring some species over others, at least in Europe.... Read more »

The incorporation of current scientific research and understanding into on the ground conservation projects not only increases the effectiveness of those conservation efforts, it also builds support for their implementation. A new case study serves as an example of the benefits that come from outreach work that includes creative methods for communicating science to diverse audiences...... Read more »

A recent study published in the Public Library of Science by Eric Lind and John Parker raises doubts about a commonly accepted hypothesis explaining the success of exotic plants in their non-native ranges.
This study sought to assess the validity of the novel weapons hypothesis, which argues that native predators are unable to cope with exotic plants’ biochemical defenses because they have simply not had enough time to adapt to do so.... Read more »

when it comes to protecting land by purchasing the property or the underlying development rights, there has been a growing push to create systematic approaches to prioritize efforts. A new study further contributes to these approaches by integrating another important social variable - the willingness of landowners to sell their property...... Read more »
