Travel and Adventure: Good times, good deed at Arbor Day Farm

Travel and Adventure: Good times, good deed at Arbor Day Farm | #TreeNews | Scoop.it

By Glenda Winders It’s too bad the Disney parks have laid claim to the phrase “happiest place on Earth” because I would make the argument that the title rightfully belongs to Arbor Day Farm in Nebraska City, Neb. This is where the Arbor Day commemoration took root, and it’s also where those tiny trees in plastic tubes come from when people make donations to the cause of reforestation — the Arbor Day Foundation’s No. 1 goal. There’s a cheerful, wholesome feeling around the farm

Santorini tree rings support the traditional dating of the volcanic eruption

Santorini tree rings support the traditional dating of the volcanic eruption | #TreeNews | Scoop.it
Will the dating of the volcanic eruption of Santorini remain an unsolved mystery? The question whether this natural disaster occurred 3,500 or 3,600 years ago is of great historiographical importance and has indeed at times been the subject of heated discussion among experts. After investigating tree rings, scientists have concluded that the volcano erupted in the 16th century BC, rather than any earlier than that.

Pine forest particles appear seemingly out of thin air, influence climate

Pine forest particles appear seemingly out of thin air, influence climate | #TreeNews | Scoop.it
Pine forests are especially magical places for atmospheric chemists. Coniferous trees give off pine-scented vapors that form particles, very quickly and seemingly out of nowhere. New research elucidates the process by which gas wafting from coniferous trees creates particles that can reflect sunlight or promote formation of clouds.

Forest model predicts canopy competition | Brown University News and Events

Forest model predicts canopy competition | Brown University News and Events | #TreeNews | Scoop.it
Scientists use measurements from airborne lasers to gauge changes in the height of trees in the forest. Tree height tells them things like how much carbon is being stored. But what accounts for height changes over time — vertical growth or overtopping by a taller tree? A new statistical model helps researchers figure out what’s really happening on the ground.

A new NASA study shows that the appearance of canopy greening is not caused by a biophysical change in Amazon forests, but instead by a combination of shadowing within the canopy and the way that satellite sensors observe the Amazon during the dry season.

A Finnish-Brazilian project is constructing a system that could estimate the dynamics of animal populations by using sound recordings, statistics and scientific computing. The canopy in a Brazilian rainforest is bustling with life, but nothing is visible from the ground level. The digital recorders attached to the trees, however, are picking up the noises of birds.

Cities support more native biodiversity than previously thought | #TreeNews | Scoop.it
The rapid conversion of natural lands to cement-dominated urban centers is causing great losses in biodiversity. Yet, according to a new study involving 147 cities worldwide, surprisingly high numbers of plant and animal species persist and even flourish in urban environments -- to the tune of hundreds of bird species and thousands of plant species in a single city.
