    on May 31, 2017 at 5:33 pm

    Imagine being a scuba diver and leaving your air tank behind you on a dive. That's essentially what humans are doing as we expand our footprint on the planet without paying adequate attention to impacts on other living things, according to researchers. Both ominous and hopeful, a new report paints a picture of the value of biodiversity, the threats it faces and the window of opportunity we have to save species before it's too late. […]

  • Spotted owls benefit from forest fire mosaic
    on May 31, 2017 at 12:44 pm

    Fire is a crucial part of the forest ecosystem on which threatened spotted owls rely, but climate change and decades of fire suppression are changing the dynamics of these forests. A new study examines California spotted owl habitat use and shows that while owls avoid the badly burned areas left behind by massive stand-replacing fires, they benefit from habitat that includes a mosaic of burned patches of different sizes and degrees of severity. […]

This allows abundances of multiple species to be estimated from camera trapping data -- information critical to effective wildlife management and conservation. […]

  • Assessment concludes urban forests in Chicago region face a warmer, wetter future
    on May 9, 2017 at 4:19 pm

    A first-ever assessment of urban forest vulnerability to climate change in the Chicago region suggests that native tree species in a 7-million-acre area may decline while invasive species may thrive with shifts in habitat suitability. […]

  • Larger swaths of tropical forest being lost to commercial agriculture
    on May 9, 2017 at 4:19 pm

    Larger patches of tropical forest are being cleared in recent years to make way for industrial-scale agriculture, a new study shows. Analysis of deforestation maps shows that roughly half of the increase in tropical forest loss from 2000 to 2012 was linked to the expansion of these large-scale activities. The trend is most pronounced in Southeast Asia and South America. […]

  • Study refutes findings behind challenge to Sierra Nevada forest restoration
    on May 9, 2017 at 1:36 pm

  • New look at satellite data questions scale of China's afforestation success
    on May 3, 2017 at 12:02 pm

    China has invested massive resources into halting and reversing tree cover loss. However, 'planting trees is not the same as gaining forests.' It is likely that much of China's tree cover gains consist of low-height, sparse and/or scattered plantations, which are unlikely to provide the same benefits as natural forests, such as diverse habitats for wildlife, prevention of soil erosion, and timber resources. […]

  • Researchers track impact of Brazil's 'Soy Moratorium' on an advancing agricultural frontier
    on April 29, 2017 at 1:50 pm

  • Shale gas threat to forests can be eased by consolidating infrastructure
    on April 19, 2017 at 2:08 pm

    Fragmentation of ecologically important core forests within the northern Appalachians -- driven by pipeline and access road construction -- is the major threat posed by shale-gas development, according to researchers, who recommend a change in infrastructure-siting policies to head off loss of this critical habitat. […]

  • Prescribed forest fire frequency should be based on land management goals
    on April 18, 2017 at 4:08 pm

    Researchers have studied forests subjected to different frequencies of fires to determine what effects fire can have on oak forests over long periods of time. They found that the frequency of prescribed forest fires should be determined based on the long-term goals of land managers. […]

  • Flammable floodplains are weak spot of Amazon forest
    on April 10, 2017 at 11:42 pm

    Peripheral parts of the Amazon forest were long thought to be most vulnerable to climate-induced collapse. Now, a study that seasonally inundated areas in the heart of the forest may be an unexpected Achilles’ heel. Those floodplains turn out to be particularly prone to fire which may subsequently spread into the surrounding forest. […]
