Question
I have raccoons in my attic. Before I evict them, I want to provide an alternate place for them to go. There aren’t really enough trees around here anyway, so I want to make a raccoon house or two. Do you have any plans you could recommend? Also, in order to deter them from trying to get back in, is it true that they dislike wire/hardware cloth, and so I could reinforce those areas with that on the outside?
They shouldn’t be pregnant yet, should they?
Answer
Raccoons usually breed in the end of January into February, but that is not a concern for your issue. Even sows with young can move from one “den” site to another. You will need to remove the raccoon prior to repairing how the animal got in. You need to be absolutely sure that the raccoon is not in the attic before you exclude it. If you simply put up a box and fix your house, that will likely not solve your problem. The raccoon will likely try and get back in your attic, which is their “den tree” from the animal’s perspective. You can lawfully trap and relocate raccoons without a permit. Check out the Indiana Department of Natural Resources (IDNR) Wildlife Removal website for more information
A resident landowner or tenant can legally capture these species of wild animals listed above without a permit on the property that he/she owns or rents if the animal is:
The landowner/tenant also can designate another person to take the animal for them if:
Within 24 hours of capture, the person who takes the animal must release it or euthanize it. Animals that are released must be released on land in the county where it was captured. Furthermore, the landowner or property manager must give permission for the release. These nuisance animals cannot be possessed for more than 24 hours and cannot be sold, traded, bartered or gifted.
For excluding the raccoon, or others, from your attic, you will need to use good materials. Hardware cloth or metal flashing typically work well. It isn’t that they don’t like those materials, they are sturdy enough to hold up. Also, repairing the damage to its original constructed method is good. Usually where animals enter it is either worn or damaged areas, or gaps in construction (even in new houses).

There has been much debate in the popular press lately regarding the role of timber harvesting on forest communities. A common focus of this debate is the perceived impacts to wildlife. Most believe that leaving our forests alone is best for wildlife. However, to provide habitat for all of our native forest wildlife species, forests need to be diverse in terms of age, species and area. Harvesting timber is the primary means of achieving this structural diversity. The purpose of this article is to summarize some key points regarding the effects of harvesting on reptiles and amphibians. These points are drawn mostly from the Hardwood Ecosystem Experiment (HEE), an ongoing research study in southern Indiana. Its primary focus is to study forest management and its effects on plants and animals. A more detailed summary may be found in Forest Management for Reptiles and Amphibians.
There has been several large-scale studies that have investigated the effects of tree canopy removal on amphibians and reptiles. These include the HEE in Indiana, the Missouri Ozark Forest Ecosystem Project (MOFEP), and the Land-use Effects on Amphibian Populations (LEAP). Much of the work from these projects has been published in the scientific literature. All of these studies demonstrate that the response of amphibians and reptiles to timber harvesting is variable—it cannot simply be quantified as good or bad. Indeed, avoiding negative impacts to all reptiles and amphibians as a result of timber harvesting is neither possible nor desirable since disturbance-dependent wildlife species1,2 and many mature forest species3, require early successional forests.
Timber Rattlesnake
For the focal species studied on the HEE, most exhibited moderate or no response in 1-3 years following timber harvests. The focal species I and colleagues have studied were timber rattlesnakes (Crotalus horridus), eastern box turtles (Terrapene carolina), and terrestrial salamanders. Timber harvests had no effect on the area male or female adult timber rattlesnakes used during the active season. There was no evidence that snakes changed movement behaviors to avoid clearcuts4. Indeed, several snakes were observed within clearcuts for several weeks and across multiple years. Annual survival of rattlesnakes on the HEE sites was high during the active season (72-98%) and winter (97-99%). Timber harvesting had no impact on survival. Declines in female survival was most affected by declines in prey abundance the previous year which were due to tree mast failures5. The level of acorns and nuts (i.e., mast) produced in woodlands naturally vary from year to year. When the small mammal population declined due to mast failure, these snakes were apparently impacted the following year.Eastern Box Turtle
For box turtles, there was no effect of timber harvests on home-range size, but the average daily distance traveled by turtles decreased by 30 percent following harvest, and turtles maintained 9 percent higher body temperatures6. Temperatures in harvest openings were 29 percent warmer in the summer and 31 percent colder in the winter than forested sites. Despite this change, turtles continued to use harvest openings during the active season, but tended to make shorter, more frequent movements in and out of harvests. Turtles likely used harvest edges for cover, thermoregulation and, possibly, foraging opportunities6. Harvested areas offered potential hibernation sites based on soil profile temperatures, slope aspect and depth of hibernation7. Both active and hibernal data suggest the level of harvesting on the HEE has modest effects on box turtle behavior, at least in the short term. To date, there is no evidence to support whether these changes have any impact—positive or negative—on box turtles.Woodland Salamanders
The response of woodland salamanders to harvests was species-specific8. The relative abundance of eastern red-backed salamanders (Plethodon cinereus) and northern slimy salamanders (Plethodon glutinosus) declined from pre- to post-harvest in patch cuts (1 to 3 acres) and clearcuts (10 acres). Red-backed salamanders also declined in control sites, suggesting factors other than the harvests contributed to salamander declines over the study period. However, red-backed salamander declines observed in control sites were not as severe as those seen within patch cuts and clearcuts, indicating harvests were at least partially responsible for observed declines within the harvest boundaries. The relative abundance of northern zigzag salamanders (Plethodon dorsalis) did not decline from pre- to post-harvest in any harvest type, and increased on sites adjacent to clearcuts.Forest management sometimes leads to short-term loses for some species but is critical to the long-term sustainability of many other species. Looking at the responses of just a few species, within cutover areas for a few years paints an incomplete picture. A large-scale, long-term perspective is necessary when considering forest management. This is the true value of well-designed studies such as the HEE. With experimental control and replication, researchers can untangle the story on what are the true effects of forest management over a large area over many decades. The HEE has shed light on many answers so far. We can look forward towards many more to come.

Hellbender release – Purdue biologists help a release attendee place a Hellbender in its temporary holding pen. Photo credit: Marci Skelton.
The Hellbender salamander is North America’s largest salamander. It is fully aquatic, living its entire life in rivers and streams throughout the midwest and southeast. Hellbenders require cool, clean rivers and streams with rocky substrates to thrive and reproduce. Unfortunately, over the past several decades the species has declined or disappeared from many of these areas. In Indiana, the species can only be found in the Blue River in south-central Indiana where there remains only a very small, geriatric population incapable of sustaining itself. In order to save the species in the state, Purdue University and its many partners have joined together to reverse the decline.
On November 1st and 2nd of this year, Purdue FNR’s Williams lab released 80, 4-year old Hellbenders into a site chosen as the best Hellbender habitat in the Blue River. Members from Purdue University, Mesker Park Zoo and Botanic Garden, Columbian Park Zoo, Fort Wayne Children’s Zoo, Indianapolis Zoo, the Indiana Department of Natural Resources, the Indiana Department of Environmental Management, Duke Energy, and more all helped in the task of releasing the individuals into their new homes.
The chosen Hellbenders had been raised in captivity at Purdue University. Unfortunately, captive-raised animals are often times not equipped with the necessary set of skills to survive life outside of an aquarium. However, these were not all aquarium-raised individuals more akin to pets than wild animals. Forty of the individuals were raised in specially designed tanks called raceways that incorporated water flow to mimic that found in a natural river setting. The remaining forty individuals were raised in standard, low-flow conditions. The idea behind raising the animals in these differing conditions is to compare whether or not the individuals raised in conditions that are more natural (i.e., higher flow rates) will be better able to survive the varying water levels they will encounter in the wild than those that are raised without flow.
In order to document success, all 80 Hellbenders were implanted with radio-transmitters. These transmitters emit a signal that allows biologists to detect them with antennae and locate the exact location an individual is hiding. For the next six to ten months, through rain, snow, and shine, Purdue biologists will follow these animals to document their behavior, habitat preferences, and whether or not they survive life in the wild.

The outcomes of this study could help solve two major problems facing Hellbender conservation. The first is that the addition of Hellbenders into the system could help spur natural reproduction and help to start stabilizing the system. This small step is important towards our eventual goal of repopulating the Blue River and other former Hellbender streams. The second problem this study will hopefully address is the issue of poor survival of captive-reared animals when released into the wild. If we find that raising animals in more natural conditions improves survival over those raised in the more common no-flow conditions, this technique could be easily adopted at captive-rearing facilities throughout the nation and help increase the overall success of Hellbender conservation in the United States.
