“When we see land as a community to which we belong, we may begin to use it with love and respect.” Aldo Leopold spoke these words many years ago, but they still ring true today. We all belong to a community, built around the people and the places we love and feel connected to, including trees and the land. Trees help shape communities and create sentimental landmarks that connect people and places. Consider the large elm that may hold a family tire swing, or the oak that made the perfect place for a secret club house, perhaps it’s under a crabapple tree that a couple shared their first kiss, trees becomes fixtures in our lives, bookmarks for the moments we relish.

Whether you see urban trees as art, infrastructure or the lungs of your community, they are important assets in our state. And recently released tree canopy data from the DNR’s Urban Forestry program shows exactly where those trees and other woody vegetation exist in the state’s municipalities and urban areas.

The Madison Community Foundation announced in February a $75,000 grant intended to help local community organizations utilize wood from ash trees that were felled due to emerald ash borer for education and artistic projects. Continue reading “Community grant to utilize their ash”

The Urban Forestry program’s recently released Urban Tree Canopy data shows the extent of tree and shrub cover across every Wisconsin municipality and urban area. The City of New Berlin in southeast Wisconsin offers a glimpse into the kind of information you could derive from the canopy data. Continue reading “A Glimpse into New Berlin’s Tree Canopy”

The second of three sessions for Wisconsin’s Community Tree Management Institute (CTMI) was held February 6-7, 2018 in Green Lake. Through hands-on training and exercises, twenty-six students from across the state learned how to identify community forestry management needs and get the work done. Topics included: inventories, management plans, urban and community forestry operations (planting, pruning and removal), natural areas, tree biology, hardscape conflicts, soils, risk tree management and tree emergencies. Instructors for session II included: municipal forestry staff, university staff, consultants and DNR staff. The variety of instructors, their perspectives and interactive components are meant to appeal to all learning styles.

The Wisconsin Urban Forestry Council recently announced award recipients honoring those dedicated to protecting, preserving and increasing the number of trees that line city streets, fill community parks and beautify neighborhoods throughout the state.

The 2018 WAA/DNR Annual Conference was held February 18-20 in Green Bay, Wisconsin. This year there was a record attendance of 857 people. Those in attendance were from the private industry, business owners, municipal staff, and state employees. Again, this year there were several different tracks attendants could attend: general sessions, climbers corner, introductory, business and utility. Across these tracks many topics were covered, from insects and pests to climbing and building an arboriculture business. This three-day conference also hosted many different exhibitors from the industry to provide attendees with up-to-date technology, equipment and practices to improve their work. Continue reading “2018 WAA/DNR Conference was an immense success”

A new Wisconsin Wildcard is available on beech bark disease (BBD). Wisconsin Wildcards are pocket-sized, collectible informational pieces available at Wisconsin state parks. The BBD Wildcard may be viewed at https://p.widencdn.net/clz4yw/Beech-bark-disease-wildcard and ordered by emailing a request to Forestry.Webmail@wisconsin.gov (ask for publication no. FR-218x).
Beech bark disease will eventually become a problem wherever beech is found. The native range of American beech (Fagus grandifolia) extends into the eastern third of Wisconsin. BBD is the result of a relationship between exotic scale insects and a Neonectria fungus. The disease was first identified in Wisconsin in 2009. Currently, the only known area of the state which has experienced mortality from BBD is Door County.
The scale insects feed by inserting their mouthparts through the bark on the trunk and branches and sucking the sap from the tree. The fungus, which “hitchhikes” on the scale insects’ bodies, enters the tree through those wounds. The tiny scale insects secrete a white waxy protective covering; when scale populations explode and there are millions of scales on a tree, the tree can appear white from a distance, making it resemble a birch tree. As the fungus enters the tree at numerous points and dead spots under the bark (called cankers) form, the tree becomes weakened, leading to a risk of “beech snap.” Beech snap can occur unexpectedly when the tree still has a full canopy of leaves remaining. Beech snap can create huge problems for park and campground managers who are trying to keep guests safe; there is no way to predict when a tree is going to fail from BBD.
Eventually, the insects and disease take their toll and the beech trees decline and die. Any age of beech tree can be infested, so in stands with significant beech mortality, regenerating trees will become infested as well as mature ones. The good news is that three to five percent of American beech trees are resistant to BBD. Michigan has identified and propagated such trees for a number of years, and have established a seed orchard of resistant trees. BBD is not yet as established in Wisconsin, but already we’ve been able to identify a couple of resistant trees in the area where BBD has killed many trees.

Forest health has relayed the message over the last few years that stand level ash mortality from emerald ash borer (EAB) is occurring in southeast Wisconsin and along some parts of the Mississippi River. Those areas of mortality continue to progress each year, but stand level mortality is no longer limited to just these areas.
February and March are good times to look for woodpecker damage to ash trees (known as “flecking”), and potentially find new EAB infestations or expansions of known infestations. Winter scouting has allowed us to detect ash mortality from EAB in unexpected places. I was in Adams County in mid-February looking for EAB biocontrol release sites. I was shocked to find a stand where all the ash trees were heavily flecked and likely dead or close to it. We had not previously confirmed EAB in that township or any of the townships directly surrounding it.
This incident further drove home the point for me that even isolated patches of ash are not safe from EAB. We are now past the point of thinking about taking action in ash stands in southern and central Wisconsin; we must now move forward with site assessments, with salvage/pre-salvage harvesting being a high priority for management. In addition, non-ash regeneration growing should be started sooner rather than later. Of course, in urban settings, now is the time to prophylactically treat high-value ornamental ash trees.
The EAB silviculture guidelines will be revised in 2018; stay tuned.
