Mountain Lion Happenings

Puma concolorThe Mountain Lion (Puma concolor) is an elusive mammal and the largest member of the cat family in North America. Other names for this animal include: Cougar, Puma, Panther, Catamount and many local variations including the Wisconsin Puma and Florida Panther. As of late, this creature has been receiving some attention locally. 

Last month a sighting was confirmed near Janesville, WI. It was the first confirmed sighting in Wisconsin in a century, although there have been hundreds of ‘probable’ accounts. A mountain Lion was killed by a train in downstate Illinois in 2000 and ’possible’ and ’probable’ sightings have been common since. Most of the sightings have been along the Mississippi River corridor and in Shawnee National Forest.  

Here in JoDaviess county, sightings have been occuring for several years now but no solid evidence yet. Last week I was called to investigate a possible sighting of a cougar in a tree. After an hour of tracking and searching for hair samples we declared the sighting as ‘possible’.

One of the pictures used in the false emailRecent Email Hoax - Coincidentally, two weeks ago an email started to circulate around the area. This email stated that a Cougar was seen near Elizabeth, IL on someone’s deck. Four very eerie pictures were attached and it provided some good shock value. However, the pictures originated from Montana in 2003 and the same email and pictures has started rumors in different parts of the country. Some people contacted me about it, Thank you. If you received this email, IDNR officials have told us that it is not true. A quick Google search will also confirm this.

What does all of this mean? Well, Cougar populations have been rising out west and some individuals have moved eastward. Cougars have the largest range of any mammal on the continent. Being able to cover 75 miles a day, cougars will expose themselves occasionally. The probability of sightings will increase during their high travel months. Hunting and bounty killings essentially eliminated the Cougar from existence in this area 100 years ago. With that pressure now removed, reproduction and survival rates can increase. We can expect this trend to continue and expect to have more ‘confirmed’ sightings in the Midwest in the future.

Merry Christmas (Prairie)

Merry Christmas Prairie - Mineral Point, WIS How do I incorporate Christmas and prairies? I know, I will write about ‘Merry Christmas Prairie’ in Mineral Point Wisconsin. Merry Christmas Prairie is a 43-acre prairie restoration that was conducted jointly by the Wisconsin Historical Society and the Wisconsin Conservation Corp begining in 1988. It is located around Pendarvis/Merry Christmas Mine, both Wiconsin state historical sites. Merry Christmas Mine began operation on Christmas day in 1905. The surrounding prairie was planted in order to emulate the pre-settlement landscape that the early cornish miners of the area would have encountered in the 1820s. Altough the prairie itself is mediocre in quality, it’s association with the regions mining history makes it notable.

One of the most interesting tidbits about lead mining and local botony is the use and nameing of Amorpha canescens, Leadplant. Leadplant, technically a shrub, indicated the presence of lead beneath the surface. Due to its extremely deep taproot, Leadplant utilizes verticle crevices in the bedrock to reach for nutrients. Early miners looked for Leadplant and assumed mineral rich bedrock would lay underneath. Groves of Aspen trees also served this purpose - most likely Populus tremuloides, Quaking Aspen. Today, Leadplant is still found growing in prairie remnants throughout the Driftless Area and is a plant that I include in most prairie restorations that I perform.

Old Mine revealed after a controlled burn Before there was a 1849 gold rush in California there was a 1827 lead rush around Galena. Today, there are many remnants of the mining era that survive in the area. It is quite common to come across an old mine when walking through the woods around Galena, Shapville, Council Hill and Shullsburg. Although 150 years of weathering make them difficult to recognize they are usually defined by 3-8 foot deppressions in the soil with a gravelly base with no other explanation of its cause. The last lead mining operation in the region closed in 1977 at Shullsburg.

Lead Furnace Replica at Merry Christmas MinePendarvis and Merry Christmas Mine and Museum is a great way to learn about early lead and zinc mining operations in this area. There are many artifacts and descriptions of the lead mining process on the self guided walking tour around Merry Christmas Mine. A few hours at the site makes for a great education for anyone curious about how the mining process worked.  

An odd name for a prairie and a very heartfelt greeting this time of year. Merry Christmas to everyone - Cory -

Bobcats

Lynx rufusRecently, a bobcat was sighted within the city limits of Galena, ILL. This serves as a reflection of the status of the bobcat population regionwide. The last two decades has seen a surge in the population, especially in Northwest Illinois and adjacent Iowa.

The Bobat (Lynx rufus) was once a contemporary of bison, elk, and wolves in the wild pre-settlement times. The changing of the landscape to agriculture and bounty killings in the 1800s led to plummeting populations. High pelt prices, indiscriminate killing and little government protection in the 1900s continued this trend. In the 1980s the Bobcat was thought to be absent from the agricultural Midwest. During the late 1970s Illinois and Iowa placed the Bobcat on their lists of state-threatened species. During the 1990s sightings became more common and by 1996 92 of Illinois’ 102 counties had at least one reported sighting. The Bobcat was removed from the threatened species list in Illinois in 1999 and from Iowa’s in 2003. Iowa is currently conducting its first Bobcat trapping season this fall in over three decades. Wisconsin, always having a stable population in the Northern half of the state, is now experiencing common sightings in the Southern half.

Why is this happening? There are several reasons. First, popularity of trapping and pelting has decreased as has the pelt price for Bobcat. The average pelt price in 1982 was $70.67 in 2003 that price had dropped to $67.23. That has left little encouragement for the trapper. Secondly, several states banned the sport including Illinois, Iowa and Indiana allowing the population to rebound. Third, the threat of Bobcats to farmers has decreased as farms have become less diverse. Fourth, land use has changed as more goverment programs are available to create wildlife habitat and more recreation grounds are purchased.  Therefore, the Bobcat can increase its range.

The driftless area offers great habitat for Bobcats. Its steep ravines with small caves offer excellent den opportunities and shelter. Early winter offers the best time to see and hear Bobcats. The males begin to squall and yowl to gain attention of passing females during the night during upcoming mating season. With open woods and a cover of snow one must keep their eyes peeled to catch a glimpse of the wild cat of the Midwest.

Hardscrabble Prairie

Just Southeast of Hazel Green, WI is the diverse Hardscrabble Prairie. Named after the original name of the village to be Hazel Green, it is a 140 acre tract. Composed of woodlands, intermittent streams and some oak openings it is the dry prairies that are in the greatest condition and are most notable.

At this natural area you can view the habitat that harbors the globally rare Ottoe Skipper Butterfly along with several rare birds and plants. The fact that one of the dry prairies is located on a North facing slope makes this natural area most interesting. Dry prairie plant communities are usually found on South and West facing slopes as the soil can dry faster and soil tempetures tend to remain at higher degrees.

This prairie is Wisconsin State Natural Area #322 and was officially dedicated in 1997. It is a great representation of dry prairies in the driftless area and makes for a great wildlife watching opportunity.

Thomson-Fulton Prairie

Thompson-Fulton Prairie - AugustJust a few miles South of Thomson, IL, and a few miles North of Fulton, IL, is the appropriately named Thomson-Fulton Sand Prairie Nature Preserve. Thomson-Fulton is a 212-acre sand prairie that is a great representation of typical Illinois sand prairies. It also serves as a great alternative to those who cannot gain access to The Savanna Army Depot.

Thomson-Fulton has great plant diversity and looks different each time I visit. Being the vegetation is sparce and short, it makes for an easy walk. Reptile lovers may find this prairie particularly interesting as snakes and lizards are found in great numbers. The six-lined-racerunner (Cnemidophorus sexlineatus) are in very healthy numbers here. The state record Bullsnake, Plains Hognose Snake and Eastern Garter Snake were all recorded here in 1997. This prairie serves as a great area for ecological study by scientists from both Illinois and Iowa.

Thomson-Fulton is highly reccomended prairie to visit. It is located west of route 84, 1.25 miles North of Lock Rd.

Wet July in JoDaviess Co.

At month’s end today all reporting stations in the area reported more than average rainfall totals. The reports varied greatly as there were lots of isolated thunderstorms that produced heavy rains. The reporting station in Dubuque, IA recorded the highest amount with 8.84 inches, far more than the 3.73 inch normal. The Galena Territory reported 4.03 inches with 2.16 inches of that falling on the 17th and 18th, Mt. Carroll reported 6.09 inches and Stockton reported 3.40 inches for the month. Looks like the reporting station on Bethel Road near Stockton missed some of the soaking rains.

The temperature average was one degree cooler than normal. After a dry May we have caught up to near average precipitation for the year. After being dryer than normal for the past five years, lets hope that this continues.
