Turtle Snuffs Out Fire

Summer 2010 Newsletter, Lost Mound Insert

The Lost Mound prescribed fire program was scheduled to begin on April 1 with 900 acres to be control burned. Many preparations had been completed and Refuge staff eagerly looked forward to this high intensity activity. Burn plans had been written, state permits had been approved, fire control lines had been established, portable water tankers/pumpers were filled and ready for action, firefighters from various stations had been recruited, and the drip torches, fuel, and tools were loaded into trucks. The excitement of firefighter staff could be compared to the night before Christmas but instead of brilliantly wrapped gifts, there were visions of flames and smoke rising from the prairie against a background of charred cedars and the knowledge that reinvigorated prairie grasses would soon be shooting towards the sky.

Then, on March 31, one day before the torches were lit, I received a numbing telephone call – Turtle Rangers Pam Johnson and Beth Pomaro had found an ornate box turtle emerging from hibernation. As I hung up the phone, a great sense of anxiety came over me as I sat dazed in my office. I had feared this situation would happen because there had been near record warm temperatures since mid-March. These warm temperatures were the reason that turtle searches were being conducted earlier than normal; during 2009, turtles had not started to emerge until April 17.

My numbness slowly wore off and I knew there was only one answer – stop implementation of the burn program in all Refuge grasslands. This decision would also impact burning at the Thomson Research Natural Area and ultimately affect over 1,000 acres of planned habitat restoration for spring 2010. A feeling of great satisfaction quickly set in as I realized this was the reason that we are conducting the ornate box turtle study in the first place, so that management techniques will conserve and protect this imperiled species.

Box Turtle Population Ups & Downs

The March 31 find of a box turtle emerging from hibernation at Lost Mound turned out to be a very significant find. The turtle was found near the hibernation location of a turtle (one of only two known turtles on Lost Mound) that had a radio transmitter attached. This turtle did not have a transmitter attached, so it was initially thought that the turtle had shed the transmitter during emergence because it was five feet from the known hibernation location. Upon examination, we discovered that this was a new turtle. This significant find of a new turtle was exciting because there had previously been many efforts dating back to the 1990s to find ornate box turtles with only three turtles being found – two were in the early 1990s and one in 2009. All of these turtles were males. The fact that the radioed turtle had hibernated so close to this newly found turtle indicates that he probably sought out (travelled two miles) other turtles in the neighborhood. This find would help us concentrate our future search efforts to this general area amongst the vast 4,000 acres of sand prairie and would increase our known box turtle population at Lost Mound from two to three individuals, a 33% increase!

But the good news was short-lived when on April 16 researchers found a radio transmitter minus the turtle (named Speedy) that it was attached to. The transmitter had several bite marks, indicating that a predator (possibly a coyote or raccoon) may have dined on rare reptilian cuisine. Hopefully, the turtle escaped but a search of the area revealed no trace of the turtle and no turtle parts. Our known box turtle population suddenly plummeted back to two turtles, a 33% reduction!

The Turtledogs Are Comin’

The Tennessee Turtledogs will be bringing their keen sense of smell to Lost Mound in May to search for the elusive ornate box turtle. These specially trained Boykin spaniels have worked on several eastern box turtle research projects and annually sniff out 500-1,000 turtles in other projects. They will be especially stylish in their first Illinois appearance with their specially made Kevlar booties to protect their feet from the prickly pear cactus! We have high hopes that the Turtledogs will find a remnant population of box turtles at Lost Mound that our human search efforts have overlooked.

Head-started Turtles

The four headstarted ornate box turtles currently being raised at the Niabi Zoo are scheduled for release at Lost Mound during June. These turtles were hatched in August 2009 and have been raised in captivity to allow a d v a n c e d b o d y development before being released into the wild. The 10-month-old turtles will weigh over 100 grams, which is equal to a 7-8 year old wild turtle. They will be affixed with radio transmitters so that we can monitor their movements.
