Forest tent caterpillar larvae emerging from egg mass.
Forest tent caterpillar egg surveys conducted in northern counties indicate hardwood defoliation from this native insect will remain low in 2019, sustaining a 16-year trend. The last FTC outbreak affected northern Wisconsin from 1999 – 2002. Cooler and wetter than average spring weather may indirectly reduce caterpillar populations by enhancing the activity of pathogenic fungi. Please report any possible defoliation to your regional forest health specialist.
To learn more about this insect, visit the DNR forest tent caterpillar webpage.
Lower moisture levels in pines increase the possibility for torching pines.
A total of 51 wildfires burned in DNR Protection Areas over the past week, burning 86 acres. The majority of the fires were caused by debris burning, with several railroad and powerline fires. Four structures were threatened and all four were saved. One significant wildfire occurred in the Woodruff Area and burned approximately 40 acres before containment. Widespread rain is expected across the state into the weekend.
As starch and carbohydrate levels build up in our red and jack pine species, their moisture levels will drop significantly. Over the next week, we will be at the low point of this moisture level, and the possibility is highest for torching pines and surface fires transitioning to crown fire activity. There is also still plenty of dead grass and fallen leaves on the land that makes it easy for a wildfire to start and spread. Stay apprised of fire weather conditions by checking the DNR fire danger webpage each day after 11 a.m.: dnr.wi.gov, keyword “‘fire”.
Firewise Tip: Make sure your burn sites are completely out and not retaining heat before leaving the area!
Fire danger is at High to Very High today, May 15 in several areas. The WI DNR is suspending burning permits for debris piles and broadcast burns in many counties due to forecasted winds, low humidity and dry vegetation. Please use caution outdoors with anything that could cause a spark including chainsaws, dragging trailer chains, and even hot exhaust systems from off-road vehicles.

In 1872, J. Sterling Morton recognized the power of and need for trees. Morton helped set aside a special day for planting trees. After the success of the first Arbor Day that year, it became a legal holiday and now is celebrated across the world.
There is a lot to celebrate when it comes to trees, they shade us and reduce cooling costs, they help clean our air and water, they create a safe and inviting community, and they beautify our cities, streets and neighborhoods. Continue reading “People from across the state celebrate trees” →
May is National Asthma and Allergy Awareness Month. Did you know trees help prevent asthma and other respiratory diseases? Trees filter particles out of the air we breathe, which decreases our risk of respiratory illnesses, including asthma. One study found that in 2010, trees removed 17.4 million tons of air pollution across the US, which prevented 850 human deaths and 670,000 cases of acute respiratory symptoms.

Many guides help you distinguish between a black and a northern red oak, or between a beech and a musclewood. But for many people just trying to identify a tree outside their door, these guides might not be appropriate. Some include too many trees from out-of-state, some focus on trees only found in rural areas, and some others are weighed down by detail. Continue reading “Urban tree identification tool available” →
Money doesn’t grow on trees, or does it?
People know the many benefits that trees can provide – clean our air, beautify our communities, reduce stormwater runoff, and decrease noise pollution – but did you know trees also save you money? With technology from i-Tree you can calculate how much your trees are saving you. Now, with a new resource from the USDA Forest Service Urban Natural Resources Institute (UNRI), you can let others know exactly how much your trees are saving you.

Wildfire Report for May 2, 2019
Widespread precipitation has kept wildfire activity low lately. In the past week, 63 wildfires burned 54 acres in DNR protection areas (approximately half the state); 35 homes and other buildings were threatened but saved with firefighter assistance and 3 buildings were destroyed. Debris burning was the most common cause (30 fires); equipment was the second most common cause (17 fires). Other minor causes included power line, campfires, and ash disposal. As the vegetation dries out on the days we don’t receive rain, expect fire danger to increase, particularly in areas where standing dead grass and other dry vegetation remains.
If you choose to conduct outdoor burning, remember that a free annual burning permit is required to burn small piles of debris and to burn in a burn barrel in DNR protection areas. Burning permits are frequently suspended this time of year when fire danger increases. You must check the day’s burning restrictions every day you intend to burn by calling 1-888-WIS-BURN (947-2876) or by checking online at dnr.wi.gov, keyword ‘fire danger’. Larger piles and daytime burning requires a special permit from a DNR Ranger. Piling your debris in a campfire pit does not make it okay to burn during the day. If your property is outside a DNR protection area, check with local officials for burning restrictions.
Remove leaves and needles from your roof, around your foundation and under your deck to prevent ignition by a flying ember.
Firewise Tip: Homeowners are encouraged to make weekly checks around your home or cabin for windblown leaves and needles on your roof, around your foundation, and under decks and elevated porches; keep these areas clean. The debris that collects in these places could be easily ignited by flying embers produced during a wildfire.

The value-added wood manufacturing industry (or secondary wood manufacturing industry) includes companies that use primary wood products such as lumber or veneer to produce higher value products, such as flooring, cabinets, millwork, furniture, sporting goods, doors, windows, roof trusses, wall panels, and other building materials. The industry includes more than 800 facilities, employs more than 20,000 workers, and generates a direct economic impact $3 billion in Wisconsin (WI DWD 2019; IMPLAN DATA 2017).

The U.S. Endowment for Forestry and Communities (Endowment), in partnership with the United States Department of Agriculture’s Forest Service (USFS), announced the initiation of the Mass Timber University Grant Program (grant program) and related Request for Proposals (RFP) to promote the construction of mass timber buildings on institutions of higher learning campuses across the U.S. The intent of the grant program is to inspire interest in and support for mass timber products among the architectural, developer and building communities as well as the public, by showcasing them in highly-visible projects on university campuses.
