The Indiana Department of Natural Resources (IDNR) has released its latest video – Indiana’s Working Forests.
This video explores the origins of Indiana’s state forest system that developed after pioneer settlers cleared the original forests and left behind a nearly barren landscape.
State forests were established to demonstrate how to use science to grow and sustain healthy forest systems. Beginning with just 2,000 acres at Clark State Forest in 1903, the DNR Division of Forestry has expanded to cover more than 156,000 acres at 15 sites.
In the video, IDNR Forestry professionals discuss how management practices contribute to forest health by mimicking natural disturbances. Those practices promote regeneration of oaks and hickories that are valuable food sources for many forest wildlife species. They explain that although timber harvests have increased in recent years, the selective approach they use removes less than 1 percent of the available trees in any given year.
FNR graduate wildlife student Patrick Ruhl, Purdue adviser Dr. J. Barny Dunning, Jr., shares how the Hardwood Ecosystem Experiment provides him the opportunity to study the effects of forest management and the changes that are taking place among migratory songbirds. This project is a collaborative effort with the following sponsors: Indiana Department of Natural Resources, Division of Forestry; Indiana Department of Natural Resources, Division of Fish and Wildlife, Wildlife Diversity Section; Purdue University; Indiana Chapter of the Ruffed Grouse Society; National Geographic Society; and The Wildlife Management Institute.

Recently, questions and concerns have come to the Division of Forestry from forest landowners and Consultant Foresters regarding the sale of black walnut trees now, because of Thousand Cankers Disease (TCD).
First, an update on the status of TCD in Indiana.
The Divisions of Entomology & Plant Pathology and Forestry have conducted TCD surveys since 2011 following the first confirmed detection of TCD in the eastern United States – Knoxville, TN August 2010.
The annual surveys include two visual surveys for symptomatic trees and a trapping survey for the Walnut Twig Beetle (WTB), the confirmed vector of the TCD fungus, Geosmithia morbida.
One visual survey occurs in 10 urban areas/cities each year. The other visual survey is gypsy moth trap tenders reporting walnut trees (healthy or with dieback) near each trap location.
In 2015, the urban areas/cities survey examined 1,431 walnut trees and the trap tenders reported 842 walnut trees. Of these only 26 had dieback and none were confirmed with TCD. Since 2011 over 40 urban areas/cities totaling over 3,700 walnut trees and over 5,200 walnut trees reported by trap tenders have been surveyed and less than 2% reported dieback and none had TCD.
The WTB survey involves setting traps baited with the WTB lure. A detection survey sets traps at high risk sites (sawmills, veneer mills, log consolidation yards, green waste sites and along the Ohio border to Butler County Ohio). A delimit survey is conducted at the sawmill in Franklin County and the walnut plantation at Yellowwood State Forest in Brown County due to the detection of WTB and Geosmithia morbida, respectively, at these locations.
In 2015, 249 traps were placed in the detection and delimit surveys. 2,592 samples were examined from the traps. The only detection of WTB was from traps at the sawmill in Franklin County.
Results of the survey efforts are:
Also, there are NO reports of widespread walnut mortality from TCD in the infested states of Tennessee, Virginia, North Carolina, Maryland, Pennsylvania and Ohio.
Therefore, if you are approached to sell your black walnut trees now because the “Walnut Disease” (TCD) is coming and you should sell before it gets to your woods, the response and recommendation is to contact your consulting forester or district forester for advice, follow your current management plan and do not sell the walnut just because of TCD.
I do not anticipate rapid and widespread mortality of walnut once TCD is confirmed from an Indiana black walnut tree.

Biomass harvesting refers to harvesting where more woody material is gathered than in a traditional sawtimber harvesting. Material down to four inches in diameter is harvested along with large trees for veneer logs and saw logs. Small trees and tops are chipped and used for paper pulp and boiler fuel.
During October of 2012, a biomass harvesting project was started by harvesting a 100 acre tract of hardwood timber at the Southeastern Purdue Ag Center (SEPAC). The tract was divided into several treatment areas demonstrating various forms of harvesting including traditional clearcutting, biomass harvesting, and areas left uncut. The goal of this project was twofold: to determine the volume and value of the products produced using biomass harvesting compared to the traditional methods, and to gain a more thorough understanding of what happens to a harvest site following biomass harvesting when restoration practices are used.
The harvest site has experienced a rapid recovery of new vegetation. Forbs, shrubs, tree seedlings, and sprouts densely covered the ground and began providing new wildlife habitats and the beginnings of a new diverse forest area.
The new Extension video “Woody Biomass Harvesting at Purdue University” explores this process in further depth, showing the harvest as well as the aftermath and regrowth. It also introduces a Purdue Extension – FNR developed web application called the Woody Biomass Calculator. This calculator can be used by landowners, foresters, and wood products harvesters and managers to estimate the volume and value of several different wood product groups and tree species, including woody biomass. Before harvesting, consider using this tool to evaluate if biomass harvesting is a better choice than traditional sawtimber harvesting for you.

As we continue to burn through our nonrenewable resources at an alarming rate, it is important that we never underestimate what we can do with our resources that can be replenished. One of these, wood, is an extremely valuable material but has been underutilized in construction for one big reason: fires. Every so often, a wood structure like the 188-unit apartment complex in Richmond, BC, burned down in 2010 goes up in a blaze and hinders the support of timber construction in a big way. While this is a valid concern, there are several things to consider before abandoning hope. Most of the big building fires covered by the news have been on uncompleted buildings still under construction. This means that fire suppression systems haven’t been installed yet, and oftentimes incomplete floors lacking fire-retardant drywall, or walls of any kind, give the fire huge ventilated areas to spread. This is hardly fair to mark these fires as a failure of wooden construction. In completed buildings, close to 80 percent of fires are contained to the rooms they are started in.
Furthermore, fire damage isn’t limited to wooden buildings. Structures made of concrete, steel or other construction materials can still weaken and collapse under the heat of a fire. In fact, heavy timber resists fire very well, burning slowly and creating a layer of char that helps to preserve the structural integrity of the inside wood.A recent advancement in timber technology to note is Cross-Laminate Timber, or CLT. CLT is made from stacks of industrially dried and fully glue-coated lumber. It is exceptionally strong, multi-purpose and lightweight. Construction using CLT is quick because it is easy to prefabricate and transport. Like heavy timber, CLT produces a layer of char when burned, and when used in construction, engineers factor in this layer and use enough wood to allow charring to form while still maintaining enough internal wood to be structurally sound. Also cosmetically, CLT looks pleasing and can be left exposed, reducing building cost. CLT has been considered the future of wood-based construction and for good reason.
So with some of the negative stigma of wooden construction debunked and the values of timber buildings explained, this leaves the biggest value of it all to think about: renewability. Timber is the only 100% renewable material for building construction. One billion cubic meters of logs are produced each year in North America and Europe alone, creating 200 million cubic meters of engineered timber and done in a careful way so that forests maintain their size. This is enough material to build 150,000 offices a year. Timber also locks up carbon that was absorbed by the tree during its growth, reducing pollution. As we look to the future, we should look to the trees. It’s time for timber construction.

The central Midwest is one of the most productive biological regions in the world. It’s a place where the eastern forest intermixes with the western prairies. The terrain is gentle, the soils are rich and highly productive, and moisture is normally abundant. This combination of factors makes the region noteworthy for its agricultural productivity. The same combination of factors also produces timberlands with the finest and highest quality temperate hardwoods in the world.

Communities in developing countries have limited budgets for education. Even though they may provide a school building, they often don’t have money to buy furniture to equip it. However, low-cost, durable, attractive school chairs can be produced in essentially any region of the world from locally available wood, wood residues or semi-processed woody materials. These chairs could fill a need for economical, functional school furniture in developing countries. This six-page publication describes the process for producing these kinds of chairs.

The invasive insect has made its way to its 79th county, Sullivan County. It was recently spotted in Jennings, Pike, Scott, Spencer and Warrick counties. There are only a few counties in southern Indiana that have not been affected by the Emerald Ash Borer (EAB). In order to slow the spread of the EAB, the Indiana Department of Natural Resources (DNR) has restricted the movement of ash trees, limbs and untreated ash lumber with bark attached or any cut hardwood lumber of any species with bark attached. Visitors to DNR properties may only bring in firewood that has been certified by the USDA or DNR Division of Entomology and Plant Pathology or is free of bark. Homeowners should also be aware of this invasive species. To learn more about the EAB and what signs to look for if your tree is infected, take a look at the resources below.
