Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. ...
The trees were similar in age (32 years), size, and cropload. Fruit were harvested from trees on 3 days in October over 3 consecutive years. Immediately after harvest, fruit from each tree were hulled and cleaned, then stored at 4°C for 1 week before being evaluated. One hundred walnuts per tree were randomly ...
The researchers collected soil samples from around 26 trees growing in eight street sections in five streets in central Riga to test for concentrations of 17 nutrients and heavy metals via hydrochloric acid extraction. ...
In cities across the country, bike-sharing plans, tree-planting initiatives, and other programs aimed at enhancing urban sustainability are becoming increasingly popular. ...
In Brazil, the volunteers work alongside scientific researchers to record and measure data on tree species, collect water samples and track mammals in the Atlantic Forest, a biodiversity hotspot and one of the world's most threatened forests. ...
Included in the carbon-density model are the actual measurements of trees sampled at thousands of locations throughout the tropics. Workers from these field campaigns used established protocols that were designed to standardize data collection. ...

If warranted by the results of the sampling data, EPA may undertake additional sampling and/or mitigate exposure to contaminants through indoor air utilizing its emergency response authority. EPA will conduct groundwater sampling and analysis of samples from the existing well network during the week of October 24th. ...
Often forest fires are considered to be the most influential form of disturbance, but there are others such as insect outbreaks or wind-throws where trees are uprooted or broken by wind, particularly in storms. There are few studies that have attempted to quantify directly how wind-throws affect fluxes in carbon levels. ...
In a new study on Douglas-fir tree populations, research suggests that the trees could be selectively bred for high density wood to increase resistance to drought. ...
