New Publication! Breeding Birds and Forest Management: the Hardwood Ecosystem Experiment and the Central Hardwoods Region

HEE - BirdThe focus of forest science is increasingly shifting to the management of forests as complex systems rather than as simple agricultural landscapes—with a much greater appreciation for the interactive ecosystem processes. In addition, now for many forest landowners the ecological value of their land is at least as important as the economic return. It is, therefore, vital to understand how forest management affects not only timber production, but also the overall function of forested ecosystems.

This new publication, Breeding Birds and Forest Management: the Hardwood Ecosystem Experiment and the Central Hardwoods Regionsummarizes the effects of forest management on bird species in the Midwest based on data collected as part of the Hardwood Ecosystem Experiment (HEE) in southern Indiana and other studies. We hope this summary provides a basis for understanding interactions between forest management and forest birds as well as guidelines for bird-friendly forest management in Indiana.

New Purdue Extension website helps to protect endangered mussels in the Tippecanoe River

MusselsMussels are a critcal part of the ecosystem and work hard to keep our rivers clean. The Tippecanoe river hosts over 45 species of mussels, including six endangered ones. Mussel populations are in decline after being harvested by the millions in the 19th and 20th centuries. In an effort to restore the mussel population and keep the Tippecanoe river clean for wildlife populations as well as recreational activity, Purdue Extension has launched a new website about mussels called Heart of the Tippy

This site provides detailed information on mussels, and what we can do to help them. For example, carrying your canoe instead of dragging it over rocky-bottomed shallow water can save mussels from being crushed. It also offers an area where visitors can take a pledge to improve the Tippecanoe's water quality and protect its mussel habitat. 

Take the pledge today and help to protect the mussels and keep the Tippecanoe clean!

The Value of Constructing With Timber

Article shared in NASF May 15, 2015, E-Newsletter​
Lloyd Alter, Managing Editor​

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 often times 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 light-weight. 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 thousand 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.

INDNR shares what to do when you find an orphaned animal

​Indiana Department of Natural Resources (INDNR) recently received inquire asking what to do with an abandoned animal. The INDNR web resource titled Orphaned and Injured Animals has  steps to follow as you decide if the animal is truly abandoned.

More . . .

Got Nature? Orphaned Animals, author Brian MacGowan, extension wildlife specialist, Purdue University:
In most cases the young animal is simply "spreading its wings" and exploring or mom simply left it to get something to eat.  Fawn deer are programmed to hide and remain motionless while mom is away. The fact is wildlife rarely abandons their young.  They may leave breifly only to return.

Remember that you should never handle wild animals unless absolutely necessary. Any animal can bite you and many harbor diseases and pests that can be transmitted to people.

In Indiana, wildlife rehabilitators have necessary state and federal permits to house and care for sick or injured wild animals. If you think you have found a sick or injured animal, you can find a list of licensed Wild Animal Rehabilitators in your area on the DNR Division of Fish and Wildlife's website.

New Publication! The Hardwood Ecosystem Experiment: Indiana Forestry and Wildlife

Hardwood Ecosystem Experiment As we turn back time and take a look at the first eight years of this 100 year project, we can then help the existence and growth of Indiana trees and wildlife in the future. This new publication, The Hardwood Ecosystem Experiment: Indiana Forestry and Wildlife, shares imperative information to aid in the growth of tree species that are producing no seedlings.

Many of Indiana's forests, especially in the southern part of the state, have been dominated by oak and hickory trees for thousands of years. In recent decades forest researchers and managers in the east-central United States have recognized that these tree species are not replacing themselves with new seedlings. Recognizing this issue, many stakeholders concerned with the status of Indiana's forests convened in the late 1990s to determine the best approach to understanding this transition and to develop strategies for maintaining our oak-hickory ecosystems. As a result of the meetings of this working group, the Hardwood Ecosystem Experiment (HEE) was initiated in 2006. The HEE is intended to last for 100 years because many of the changes that occur in these forests happen over decades. In fact, many of the strongest effects of the transition from oak and hickory forests may not even be observable until we near the end of the project. This is an analysis of the first eight years of the project.

Black Bear Recently Seen Again in Indiana

​After being sighted in Indiana for the first time in 144 years on June 12th around South Bend, a second sighting of the bear has occured in the Michigan City area and this time the bear has done a little bit of damage foraging for food. The bear had knocked over multiple bee hives and tore into some food at a local farm. It also bent poles holding up bird boxes, likely eating the baby birds inside.

The Department of Natural Resources is hoping the bear will return to upper Michigan on its own, where the black bear population reaches around 15,000. However, they are continuing to monitor its movement and are prepared to trap it if needed. 

While startling, it is important to note that black bears aren't as dangerous as most people think. They are usually scared of humans, but it is a wise idea to move bird feeders, grills, and trash cans out of your yard. If you encounter a bear, the DNR recommends standing your ground and making a lot of noise, while slowly backing away. Do not turn and run. Black bears are also considered an exotic animal in Indiana and shooting or killing one is a serious offense that can result in large fines or jail time.

Please report bear sightings to or call 812-334-1137.

Purdue Tree Doctor app fights back against emerald ash borer
Purdue Tree Doctor AppThe emerald ash borer is one of the most destructive insects in the Midwest, killing tens of millions of ash trees. After first being spotted in Indiana in 2004, it has already spread to 95 percent of the state. It is possible to fight off these insects with ash tree pesticides, however in many cases it can be too late. Trees missing over half of their canopy are unlikely to be able  to carry the pesticide through their trunk to kill the borers. In order for the pesticide to be effective, landowners need to be able to identify signs of an emerald ash borer invasion.

In an effort to arm the community with knowledge and effectively deal with these pests, Purdue entomology professor Cliff Sadof and his colleagues have developed the Purdue Tree Doctor App. This two dollar application for iPhones and Android phones can save landowners from losing their livelihood to the emerald ash borers by helping them identify and diagnose early signs of infestation and guide them to treatment solutions before it is too late.

To suppliment this app, Sadof has also created a web-based emerald ash borer cost calculator to help communties make educated decisions on tree removal, replacement, and treatment by projecting costs over 25 years. With the Purdue Tree Doctor app and the EAB cost calculator, the community can more effectively take action and save their ash trees before it's too late.
