City construction leaves trees weaker long after the construction project is over and the trees have less of a positive impact on the urban environment.
As earthworms silently devour leaf litter across the country, they are changing soils, restructuring ecosystems and depleting our forests' carbon stocks.
The East Fork Fire in Western Alaska is the state's largest at the moment, estimated at more than 150,000 acres Thursday, and it's burning in a region where, just a couple decades ago, large fires would not have been expected.
Landmark report says invasive species are major threat to biodiversity and dealing with them requires global cooperation
A new study, published in the Proceedings of the National Academy of Sciences (PNAS), finds that black spruce trees — a key species on the boreal landscape for millennia — are losing their resilience and capacity to regenerate in the face of warming temperatures and increasingly frequent Arctic wildfires.
There were no bugs buzzing around the lights in the parking lot.
Trees purify the air and generate economic benefits, but unbridled development in cities is increasingly changing growing environments
The definition of farming has expanded over time from soil-only planting and harvesting to include farmers that harvest from the sea. Along the coast, kelp f...
While the world’s forests can play an important role in absorbing carbon dioxide and slowing climate change, new research indicates that elevated CO2 concentrations do not necessarily boost forests and that higher temperatures could cause changes in trees that reduce their ability grow.
The Swedish Environmental Protection Agency and Agency for Marine and Water Management want to create a national list of invasive species, and have presented ...
By Ed Struzik. This article was originally published on Yale Environment 360. Canadian scientist Philip Marsh and I were flying along the coast of the Beaufort Sea, where the frozen tundra had recently opened up into a crater the size of a football stadium. Located along the shoreline of an unnamed lake, the so-called thaw...
There are more than 20 invasive plant species in the Yukon that spread, change the makeup of the soil and generally prevent native plant species from thriving in their natural environment. here's what you can do about six of the most common ones.
Biologists want to know why there are so many moose. It may have a lot to do with shrubs — moose feast on their leaves during the spring and summer. These short woody plants are spreading west, aided by climate change, and moose populations are expanding along with them.
Berry pickers have long reported that the number of wild berries has been diminishing, and a 26-year study is now confirming the unexplained decline.
As grape harvest time nears across Greece, winemakers are worried about the impact on output from a succession of extreme weather events.
Cecelia Brooks remembers a time when the deep forest of New Brunswick was so cold, snow could still be found in its depths in August. That rarely happens anymore. Brooks, who lives on St. Mary's First Nation in Fredericton, is one of many Indigenous people in the Wabanaki region who say climate change is threatening traditional plants and medicines. Those changes, Brooks says, could alter their way of life.
The Institute of Tribal Environmental Professionals (ITEP) Tribes and Climate Change Program is publishing a report called the Status of Tribes and Climate C...
For years, populations of Sitka black-tail deer have slumped, leaving residents without a staple source of protein. A three-day summit held in Craig last month prompted lengthy discussions about the problem. When loggers cut down a section of old growth Sitka spruce, hemlock and cedar in the Tongass National Forest, there’s no need to replant — trees grow back on their own. It’s what scientists call an “even-aged forest.” When trees all start growing at the same time, they create a dense canopy that prevents light from reaching the ferns and berry bushes that black-tail deer love to snack on. And because the trees grow close together, they end up long and spindly — not the massive, thick, tight-grained trunks that make old growth lumber so highly valued.
Fall moose hunts are beginning across Alaska. In western parts of the state, biologists hope that hunting pressure will help protect the health of booming populations. They also want to know why there are so many moose in the first place. It may have a lot to do with shrubs — particularly scrubby willows shooting up at the edges of open tundra. Moose feast on their leaves during the spring and summer. These short woody plants are spreading west, aided by climate change, and moose populations are expanding along with them.
Garden writer Jeff Lowenfels asks whether there is more matter falling from birch trees late this summer than in previous years,
