Veteran trees, also known by some as heritage trees, loom large in our imagination. If you have an image of a large, gnarly oak in your head, you’re on the right track. These are the trees that, according to the International Society of Arboriculture, are of exceptional cultural, landscape or nature conservation value. They are vitally important and deserve management attention to keep them on the landscape whenever practical. Continue reading “Managing Veteran Trees In The Urban Environment”

Keep Watering In Fall To Protect Trees

By Lisa Johnson, Horticulture Outreach Specialist, Extension Dane County; Johnson.Lisa@danecounty.gov

‘Winter burn’ refers to a type of damage to evergreen foliage that typically occurs over winter. Common symptoms are browning and dying from the tips of the foliage inward. Several factors cause winter burn on evergreens, including winter ‘thaws’ while the ground is frozen, dry soil in autumn, a long period of very cold temperatures, winter sun on evergreen foliage or drying winter winds, poor siting of susceptible plants, recent planting/transplanting and the individual plant’s susceptibility. Frequently affected plants include yews, junipers, boxwood, arborvitae, rhododendrons, dwarf Alberta spruce and hemlock. Continue reading “Keep Watering In Fall To Protect Trees”

Improving Employee Well-being With Exposure To Trees And Nature

By Olivia Witthun, DNR Urban Forestry Coordinator; Olivia.Witthun@wisconsin.gov or 414-750-8744

Employee attitudes and well-being improve with exposure to nature. Think about it. Every weekday we commute to work, only to be met by a dark cubicle in shades of beige and grey. Ever wonder why your mood starts to match the walls? It’s because the workplace environment contributes to employee health. We’ve known this to be true (anecdotally) for a long time, but mounting scientific evidence proves our urban and community forests have beneficial effects on employee performance.

Once again, it’s time for nature’s majestic paintbrush to spread its magic across Wisconsin.

Many of the state’s trees have begun to show off their amazing fall colors, brightening the view for state residents and visitors everywhere – from the restful resplendence of our urban areas and state properties to the drive-by dazzlement of our tree-lined country roads.

“It’s a brilliant and colorful display,” said Scott Lyon, leader of the Wisconsin Department of Natural Resources Forest Products team. “The Badger State is home to many deciduous hardwood species which change colors and lose their leaves as the seasons change, including maple, oaks, hickories and aspen.”

Have you noticed maple branches suddenly dying this summer?

Sudden mortality of maple branches during the summer in northern Wisconsin is often a result of squirrel damage that occurred in late winter and early spring.

In late winter and early spring, gray squirrels strip the bark of maples to get at the sweet maple sap. When the damage is extensive or severe, entire trees or branches will be killed immediately and will not leaf out in the spring.

CISMAs Plan Invasive Plant Events

When it comes to fighting invasive plants, Wisconsin’s Cooperative Invasive Species Management Areas (CISMAs) are often the first line of defense (and offense).

These regional groups provide a localized resource for landowners looking for invasive plant education, identification support and assistance with controlling invasives on their properties.

Want an advantage over your taller friends? Try propping yourself up on a pair of stilts. As its name suggests, this is precisely how Japanese stilt grass operates. It uses “stilts” (branching rootlets near its base) both as support and to sprawl over nearby plants.

Japanese stilt grass (Microstegium vimineum) is an invasive, warm-season annual grass. It grows one to three feet tall and has an aggressive, mat-like growth that creates dense patches and discourages native plants from establishing. It is also a prolific seed producer, with each plant producing up to 1,000 seeds that can easily spread over land and water during its growing season.
