Relocating Turtle Nests

When the Traver Creek Project was started, one of the most interesting parts was the turtle stipulation. In order to begin the creek renovation, a permit was submitted to the Michigan Department of Environmental Quality (MDEQ.) To satisfy the MDEQ permit of the project, turtles and other herptofauna were relocated from the two inline detention basins (AKA ponds on holes #12 and #17) on Traver Creek to the pond on #8. There are at least four large snapping turtles (Chelydra serpentina) and numerous painted turtles(Chrysemys picta) in Traver Creek and there was concern over what would happen to these turtles during and after the project was completed. To help them after the project, four sand piles were created for the turtles to use as nesting areas.

Last week, a City employee noticed a painted turtle laying eggs in the lawn area of an apartment complex. These eggs would have had very little chance of hatching and those eggs that hatched would have had a hard time getting to the relative safety of the water. The employee notified Natural Area Preservation (NAP) and the staff herpetologist came out to examine the nest. He determined that the eggs would not survive and removed them. He marked the eggs because they an air bubble grows at the top. If the eggs are inverted, the embryos inside will not develop.

Nine eggs were marked and removed. This is a typical amount of eggs per nest.

The eggs were taken to the pond near #12 at Leslie. A shallow hole was excavated and the eggs placed inside. After covering the eggs with soil, a predator exclusion box was placed over the nest. This will keep raccoons and other small animals from eating them until they hatch in September.

Over the weekend, a golfer noticed a snapping turtle doing the same thing in one of the bunkers at Huron Hills.

The turtles go into a trance when laying eggs and do not respond. Please stay away from them during this process.

These eggs were removed to another location, closer to the south pond of the Huron River.

Snapping Turtle Migration

This morning, a large female snapping turtle was seen moving along Traver Creek. She was between the first bridges downstream from Traver Road and the #17 pond. This is great news because it means that at least some of the turtles we moved last fall for the Traver Creek Project have made it back to the areas they were relocated from. The photo above is from last fall, as I did not have my camera with me this morning. You can read more about the turtle relocation HERE, HERE, HERE or HERE.

Turtle relocation

As part of the Traver Creek Restoration Project through the City of Ann Arbor owned Leslie Park Golf Course, a permit was submitted to the Michigan Department of Environmental Quality (MDEQ.) To satisfy the MDEQ permit of the project, turtles and other herptofauna will be relocated from the two inline detention basins (AKA ponds on holes #12 and #17) on Traver Creek in the Golf Course.  This week, barrier fencing was installed around the pond on hole number 8 at the LPGC to receive and retain relocated animals before the construction starts.

The City of Ann Arbor's Natural Area Preservation's (NAP) staff Herpetologist, David Mifsud, will coordinate the relocation efforts with assistance from NAP staff and volunteers. The hope is that we will be able to relocate the majority of the animals from the ponds well within the time needed for them to successfully overwinter in the relocated area.  NAP will document all collected animals and monitor the receiver area(s) in subsequent years to qualitatively assess the results of the relocation.

The turtles will be live trapped with hoop traps baited with sardines. There will be six of each of three different size traps for a total of 18 traps. Here are some pictures of the traps.

The smallest trap. Notice the yellow, foam swim toy (noodle) which will help keep the trap afloat.

Here is the largest size trap.

Putting the traps out.

The traps need to be staked out so they don't float away.

These nets will help direct turtles into the traps. They hit the net and follow it until they get to the trap.

Here is the set up with one of the large nets.

This is the pond on #8 where the turtles and other animals will be relocated.

The silt fence will keep the animals from trying to move back to the pond where we are trapping them.
