The state is investigating. Listen 0:58 (htt // d The State Department of Agriculture (http://www.oregon.gov/ODA/PEST/Pages /index.aspx) found out about the bee deaths from a TV report and sent an investigator out Wednesday. Bruce Pokarney is with ODA: Pokarney: "What we've discovered is that a commercial pesticide operator had applied a pesticide, active ingredient Imidacloprid on 17 trees at the complex One of hundreds of bees that died at an apartment early Tuesday morning. Most of those complex in Eugene Tuesday. The ODA found out about the die-off from a report on KVAL trees if not all of them were Linden Credit KVAL trees. Those are the same trees that were involved in bee death incidents last year in Oregon." Last summer 50 thousand bumblebees were found dead in a parking lot in Wilsonville after pesticides were applied to Linden Trees. After that incident, state regulators required label statements on products containing chemicals that harm bees. The labels advise against spraying trees in full bloom and attracting pollinators, as in this case. Pokarney says ODA will potentially pursue enforcement action against the company, Glass Tree Care. The company says it's cooperating with the investigation. Copyright 2014 KLCC-FM.

Wednesday, June 18, 2014 at 10:52AM Joe Rankin Terrestrial invasive plants can wreak havoc with forests By Joe Rankin Forests for Maine’s Future writer Licensed forester Jeff Williams does the usual things foresters do: writes management plans, runs boundary lines, oversees harvests, lays out logging roads, marks trees. But more and more these days he’s having to deal with invasive forest plants. Pulling garlic mustard on Cutts Island (Photo: Maine Natural Areas Program)Williams, who owns Maine Forest Management in Hollis, said 30 to 40 percent of his time is spent helping his clients cope with the likes of glossy buckthorn and Japanese barberry, and that percentage goes up every year. In fact, it’s very seldom that he gets a job these days that doesn’t involve invasive plant issues. Sometimes he even does herbicide applications (he has a master applicator’s license) if a client can’t find a contractor to do the work at an affordable price. “As bad as it is now it’s inevitable that it’ll get worse,” Williams said. “As it is now there are pockets where it’s a real problem. In 50 years it’ll be a huge problem for southern Maine and forests in Maine period.” Woodland invasive plants are also known as terrestrial or upland invasives. They haven’t gotten the publicity that exotic insect pests or aquatic invasive plants have. Non-woodsy types who have heard of the emerald ash borer or recognize Eurasian milfoil on sight might give you a blank look at a mention of glossy buckthorn, black swallowwort or Asiatic bittersweet. That’s not unexpected, said Tom Doak, the executive director of the Small Woodland Owners Association of Maine. 1 of 8 6/24/2014 11:30 AM Forests for Maine's Future - Fresh from the Woods Journal http://www.forestsformainesfuture.org/fresh-from-the-woods-journal/alien... Asiatic bittersweet (Photo: Tom Rawinski, USFS)Exotic insect pests prompt more attention because they kill trees outright and the damage is highly visible; the uncontrolled spread of invasive aquatic plant species threatens to imperil the state’s thousands of lakes and ponds, said Doak. In contrast, woodland invasives are more insidious: they’re green in a landscape of green and growing things. “They don’t generally kill the trees, but they occupy the land and prevent forest trees from growing,” said Doak. An invasive plant is generally defined as one that spreads quickly and crowds out other plants and trees. Most are exotics, immigrants from Asia, Africa or Europe. Many are sunlight lovers. They invade marshes (common reed), wetlands (purple loosestrife), grassy areas and roadsides (Japanese knotweed), and field-woodland edges (honeysuckle and autumn olive.) Generally speaking, it’s harder for an invasive plant to make it in a healthy forest with a full canopy. But some have no problem. There are vines, trees and shrubs already invading forests in Maine and others that will likely be here soon. Common buckthorn (Photo: Maine Natural Areas Program)So, what species would a list of Maine’s “most unwanted” woodland invasives include? The experts we talked to reeled these off: Glossy buckthorn (Frangula alnus) and common buckthorn (Rhamnus cathartica) are fast-growing shrubs that form dense thickets in wetlands and woodlands. Their habit of leafing out before other plants and retaining their leaves late into the fall gives them an advantage and helps them shade out native species. Japanese barberry (Berberis japonicus) is, as its name suggests, a spiny shrub originally from Asia. It grows three to six feet high. It forms dense thickets that can be impossible to bull your way through. The red berries are highly attractive to birds, which help spread it. Asiatic bittersweet (Celastrus orbiculata) is the Boston strangler of invasives. This relative of American bittersweet grows fast and twines around trees as it reaches for sunlight, eventually smothering the host plant. It not only reproduces using attractive red berries, but also root suckers. 2 of 8 6/24/2014 11:30 AM Forests for Maine's Future - Fresh from the Woods Journal http://www.forestsformainesfuture.org/fresh-from-the-woods-journal/alien... A forest of barberry at Laudholm Reserve in Wells (Photo: Maine Natural Areas Program)Norway maple (Acer platanoides) is an escapee from the nursery trade. This sugar maple look-alike, still planted as a shade and street tree, grows fast, even in shade, and forms dense colonies that can elbow aside native trees and shrubs. Garlic mustard (Alliaria petiiolata) is a biennial herb that tolerates a wide spectrum of soils and growing conditions, and is especially aggressive in rich, moist upland forest soils, where it forms dense colonies of three-foot tall plants, shouldering aside all manner of native wildflowers and herbs. Black swallowwort (Cynanchum louiseae) is a viney native of southwestern Europe that likes moist soils. It engulfs native plants and creates thickets. Morrow honeysuckle (Lonicera morrowii) is a native of Asia that grows as high as 16 feet, forming dense thickets and shading out native plants. While it likes sunlit forest edges it will also invade mature forests. You’ll note some common themes in the descriptions. These invasive plants tend to be fast growing; they form dense thickets, a sort of non-compete strategy; they adapt to a wide range of habitats and they have shiny, How the 3 of 8 6/24/2014 11:30 AM Forests for Maine's Future - Fresh from the Woods Journal http://www.forestsformainesfuture.org/fresh-from-the-woods-journal/alien... invasive game usually plays out (Graphic: Tom Rawinski, USFS)brightly-colored fruit, a sure-fire reproductive strategy since birds ingest the fruit then excrete the seeds far and wide along with a little fertilizer. Some of these plants were introduced accidentally, some on purpose, either as ornamentals or for erosion control. It wasn’t until later, sometimes decades later, that the threat they posed was realized. However, even today, some, such as Norway maple and Japanese barberry, are staples of the
