Maple sugaring has always been a season completely reliant on the weather. A good sap flow comes from a warm-up during the day, and cooler temperatures at night; this year, there's an added obstacle for maple sugarers—too much snow. "Last year we were tapping third week in February. The year before, second week in February...

An Estonian oak tree in a football field has received the European Tree of the Year Award with nearly 60,000 votes. The Estonian oak tree received 59,836 votes, almost a third (32 percent) of the 185,000 votes cast in total for 14 trees from countries across Europe. All the trees join the European Trail of Trees, which...

Hawaii has started cutting down trees on 300 acres of Kauai forest reserve that were scorched by wildfires in 2012 and sending the wood to be processed at a new biomass-to-energy plant. Some 15,000 tons of eucalyptus and pine trees will be removed. Native and non-invasive species will be planted in their place. The project...

Over the past decade, USDA Forest Service researchers have been working with university cooperators to find some way to slow down or stop the relentless spread of cogongrass. This last fall, Auburn University researchers reported results that demonstrate, for the first time, that patches of cogongrass can be eliminated...

Many eastern Colorado trees were unprepared for the record-breaking cold in early November. Temperatures in Denver plunged from the high 60s to minus 14 degrees over just four days, and as a result, many trees suffered needle and bud damage that will impact tree health this year. “Foresters along the Front Range have been...

Reflecting upon the Emerald Ash Borer (EAB) situation in Illinois, 2014 was definitely a disheartening year. Sixteen new counties were confirmed positive in this year alone, seven of which were outside the established quarantine. Compare this figure to a total of 34 from when it was first detected in 2006, up to the end of...

If we’re not careful, harmful insects and plants could leave scars on Minnesota’s environment. Here is some information from the Minnesota Department of Agriculture. What is an invasive species?

Hawaii's isolation has made the island state home to more invasive species than anywhere else in the U.S. Little fire ants, coconut rhinoceros beetles, albizia trees, rats, mongoose, strawberry guava, coqui frogs, miconia, fireweed and invasive algae all share one common trait.  As invasive species, they provide examples...

In the last few years, a team of Vancouver Lower Mainland residents has yanked 74,500 pounds of invasive plants out of area parks, planting in their place 7,100 native trees and shrubs. The cost to taxpayers for all that time and effort? Absolutely nothing. The hugely successful so-called Green Team germinated in 2011 and...

Much as the Asian long-horned beetle attacked maple and elm trees on the East Coast, the coconut rhinoceros beetle could devastate Hawaii's palm trees and move on to bananas, papayas, sugar cane and other crops afterward. Adult beetles burrow into the crowns of palm trees to feed on their sap, damaging developing leaves...
