Winter is an ideal time to perform trimming, cutting and brush removal work on and near oak trees.
For one thing, it’s a low-risk period for the trees to be infected with oak wilt, a fungal disease spread by beetles. When a red oak is infected with oak wilt, it will die that year; the disease also stresses trees in the white oak group, often fatal with bur oaks and swamp white oaks.

It takes more than a village to foster healthy forests. More than a township, a city and a county, too. Sometimes, even more than a state.
That’s why the Great Lakes Basin Forest Health Cooperative (GLB FHC) was formed four years ago by Holden Arboretum in Ohio and the U.S. Department of Agriculture Forest Service.
Geographically, the group’s region encompasses an area from New Jersey to Wisconsin. The Wisconsin Department of Natural Resources (DNR) is an active member.

We are often asked difficult questions about our forests, their health and how climate change is impacting them. Here is a curated collection of resources that may help you answer some of those questions. Continue reading “Forest Health and Climate Change Resources”
The Urban Forest Improvement Program, funded by the Inflation Reduction Act and the USDA Forest Service’s Urban and Community Forestry Program, provides grants to help organizations benchmark their urban or community forests against the Sustainable Forestry Initiative (SFI) Urban and Community Forest Sustainability Standard.
These grants support the assessment of current management practices, offering valuable insights into how sustainably these forests are managed and a roadmap of opportunities for improvement. Continue reading “Sustainable Forestry Initiative Urban Forest Improvement Grant Application Now Open”

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”

Heterobasidion root disease (HRD), formerly known as annosum root rot, was recently found in Door County for the first time.
In mid-September, several suspected HRD fruiting bodies were spotted in a white spruce plantation on privately owned land in the town of Sevastopol. One cluster of fruiting bodies located at the base of a dead spruce was confirmed as Heterobasidion irregulare, the fungal pathogen that causes HRD. The other fruiting bodies were identified as a native decay fungus that has a similar appearance.

‘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”
