Study reveals effect of habitat fragmentation on forest carbon cycle

Study reveals effect of habitat fragmentation on forest carbon cycle | forestry | Scoop.it
Drier conditions at the edges of forest patches slow down the decay of dead wood and significantly alter the cycling of carbon and nutrients in woodland ecosystems, according to a new study.

It's easy to take nature for granted with all our digital developments. Forests are one of the few natural wonders left!

Trees Can Capture Up To 60% Of All Particulate Matter From Road Exhaust

Trees Can Capture Up To 60% Of All Particulate Matter From Road Exhaust | forestry | Scoop.it

Trees planted along a city street screen residents from sun and noise—and from tiny particles that pollute urban air. A new study shows that tree leaves can capture more than 50% of the particulate matter that’s a prime component of urban pollution and a trigger for disease (Environ. Sci. Technol. 2013, DOI: 10.1021/es404363m). In urban settings, particulates come primarily from car exhaust, brake pad wear, and road dust and can contain metals, such as iron and lead. The Environmental Protection Agency classifies particulates in three size ranges: less than 1 μm (PM1), up to 2.5 μm (PM2.5), and up to 10 μm (PM10) in diameter. These particles are tiny enough for people to inhale and can exacerbate heart disease, asthma, and other health conditions. Researchers want to understand how trees capture particles so that urban planners might eventually take advantage of these natural tools for mitigating pollution. However, modeling this process is challenging because air flow and particle movement on a street follow complex fluid dynamics. Models have shown wildly varying results for just how much particulate matter trees can trap, with some as low as 1% and others as high as 60%.

Europe's forests 'particularly vulnerable' to rapid climate change

Europe's forests 'particularly vulnerable' to rapid climate change | forestry | Scoop.it

Climate change is here, it’s happening now, and for the last few decades it has been demonstrably bad news for many of Europe’s forests.

An international team of researchers say in a report from the European Forest Institute that climate change is altering the environment, and it is long-lived ecosystems like forests that are particularly vulnerable to the comparatively rapid changes occurring in the climate system.

 

The report, published in the journal Nature Climate Change, shows that damage from wind, bark beetles, and wildfires has increased significantly in Europe’s forests in recent years. Windthrow − the wind’s effect in damaging or uprooting trees − is an increasing problem.

Living near trees, green spaces reduces stress, study shows

Living near trees, green spaces reduces stress, study shows | forestry | Scoop.it
"A poor person living on a logging road in (a national forest) was more likely to be happy than a wealthier person living on a treeless block in Milwaukee," the researchers said in a statement. The Trust for Public Land, a conservation nonprofit, creates the annual index by scoring cities on several open-space factors: accessibility, or the percentage of residents living within a 10-minute walk of a park; park size, which includes the median park size and the percentage of total city area dedicated to parks; the number of playgrounds per 10,000 city residents; and per capita park spending.
