As we’ve mentioned previously, California is in the midst of a solid waste crisis, driven by the twin drivers of closing biomass plants and a forest health crisis that’s killed hundreds of millions of trees. We can help you lower your electricity bills and waste disposal costs at the same time. ...
So it was bad enough when scientists said a beetle was ravaging avocado trees in South Florida. Then scientists found out that the redbay ambrosia beetle — originally determined to transmit laurel wilt — is rare in avocado groves but that six other beetle species could carry the laurel wilt pathogen. ...
When they’re infected with the laurel wilt fungus, redbay trees – a close cousin to the avocado — emit methyl salicylate to repel redbay ambrosia beetles, the very beetles that gave the trees the fungus in the first place, scientists say in a newly published study. ...
It is an ecological thermal weed-killing machine for vineyards and tree crops in general, able to produce hot foam and distribute it a targeted way under the rows of the trees. ...
The “Schiumone” (Big Foam) is an ecological thermal weed-killing machine for vineyards and tree crops in general, able to produce hot foam and distribute it a targeted way under the rows of the trees. ...
Another important focus for the research was to screen avocado hybrids for resistance to a disease called laurel wilt, spread by the redbay ambrosia beetle and its fungal symbiont Raffaelea lauricola, which kills avocado trees and threatens the crop nationwide. “We used fruit from a half-sibling population of families that originated from the National ...
In a context of climate change and forest fragility, an international consortium of scientists led by INRA1 have identified the world’s most drought-resistant tree species in the world. Results of the study, which appear in the June issue of Plant Physiology, were obtained using an instrumental analysis of the cavitation process, and provide new leads for the adaptation of ...
It first appeared in the U.S. in Georgia in 2002, and has spread around the Southeast, mostly in redbay laurel trees. Avocados are in the same laurel tree family, and once infected by the fungus the tree can be dead within six weeks. ...
The saltwater traveled nearly 2 miles into a ravine, killing grass, bushes and trees along the way. Still, disposal methods have improved in recent decades, with much of the brine now re-injected into deep geological formations. ...
In total, they identified 953 species as being associated with ash trees, including 12 birds, 28 mammals and 239 invertebrates (such as beetles). Of the total, 44 species were completely reliant on ash trees, and a further 62 were highly associated. Species reliant on ash trees included 11 fungi, 29 invertebrates and 4 lichens. ...
In addition to the Sunny Boy TL-US, this year’s winners include a commercial composting system, dimension stone that utilizes quarry waste, and an engineered wood product that is partly sourced from trees killed by the mountain pine beetle. “The products we’re recognizing this year are remarkable in their diversity and innovation,” said ...
The Rim Fire's exponential growth slowed only after hitting areas that had burned in the past two decades, and Safford says that shows the utility of prescribed and natural burns that clear brush and allow wildfires to move rapidly without killing trees. "If you look at the Sierra Nevada as a whole, by far the largest portion hasn't seen a fire since the 1910s ...
There have already been two sawmill explosions and fires in Canada that have resulted in dozens of injuries and killed four workers. The suspected culprit in both cases was combustible dust. ...
Trees throughout Africa's Sahel region — vital to peoples' livelihoods — are dying as a result of long-term drought linked to climate change, according to a study. It found that one in six trees in the region has died since the 1950s, whilst a fifth of species has disappeared locally, because of rising temperatures and lower rainfall linked to climate change. At some sites, average ...
However, construction of the Mississippi River Gulf Outlet (MRGO) inundated the area with saltwater, killing the cypress trees and leaving behind open water. In 2005, the lack of vegetation in the open water increased storm surge from Hurricane Katrina, worsening the damage it caused in the Lower Ninth Ward and St. ...
As fall turns into winter, people across the country buy or gather firewood to heat their homes, campsites, and cabins, and many aren't aware that moving firewood more than 50 miles can increase the risk of new invasive pest infestations that kill trees. A recent study, "Economic Impacts of Non-Native Forest Insects in the Continental United States" by Aukema et ...
Now that spring has arrived, and summer is quickly approaching, The Nature Conservancy, along with nursery industry partners and scientists, encourages people to take the time to learn more about tree-killing invasive insects and diseases as they spend more time outdoors. ...
The study found that the increase in dying trees has been pervasive. Tree death rates have increased across a wide variety of forest types, at all elevations, in trees of all sizes, and in pines, firs, hemlocks, and other kinds of trees. ...
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. ...
The invasive, fungal-like Phytophthora ramorum causes Sudden Oak Death (SOD), which is responsible for destroying tens of thousands of oak trees in the US. SOD has reached epidemic levels in the coastal forests of northern California and southwestern Oregon, killing large numbers of oak trees and infecting a wide range of other host plants. ...
