Shifts in job responsibilities and the ongoing boardwalk construction have kept us from blogging. Here are some of the things we have been doing.

Hog management continues to be a full-time job. As noted in previous blogs, hogs are not native to any North American habitats and they cannot exist without adversely affecting the places they inhabit.

We have had limited success in eliminating hogs from the property as they can move off of our property and they breed throughout the year. Here two adults and four young hogs inspect the trap, but avoid entering it.  Below, hogs have inflicted serious damage to a neighbors soybean field. Wild hogs cause an estimated $1.5 billion (that's with a "b") in agricultural damage each year in the United States alone. Those costs do not include damage to water quality or to native ecosystems.

Although the wild hogs near the center have learned to avoid the trap, deer, raccoons, and this bobcat cannot avoid the game camera's motion sensor.

Boundary painting is an important and never ending task. To avoid confusion at the property lines, the lines must be clearly marked. Signs are posted denoting the various state and federal restrictions on the property and survey blazes are painted to further highlight the property line location.

Currently, the Francis Beidler Forest (FBF) has 102 miles of exterior boundary lines plus an additional 30+ miles of interior boundary lines. Geographic Information System (GIS) technology is being used to manage the FBF property, but all the data must first be collected and verified. The map below shows all of the lines that are overdue for painting, have an unknown status, or are due for painting in 2013.

If you thought, "That looks like everything," you are close. However, in addition to painting when visiting the lines, location data on the survey corners, access points, and signs are gathered to be entered into the GIS database. The on-the-ground data collecting has helped us detect errors in Berkeley County's GIS database, thereby allowing them to revisit survey plats and update their files to accurately reflect our property lines. There is still work to be done with all three counties (Berkeley, Dorchester, Orangeburg) in which FBF holds parcels.

The new boardwalk continues its march and has moved beyond the fork. You can follow the progress on this map.

As construction has now moved beyond the fork, access has been restored for all individuals. Visitors will now walk out on the newly constructed boardwalk (see below) to the fork and then walk on the old boardwalk along the edge of the swamp, which is the reverse of the normal direction on the boardwalk. Once visitors encounter the construction zone on the front side of the boardwalk, they will need to retrace their path back to the nature center. Construction is scheduled to be completed by April 2014.

One does not need to go deep into the swamp to encounter wildlife. Plenty of birds are in the parking area, especially now during migration, but an occasional water snake ventures up to the high ground in search of a meal. Below a Banded Water Snake (Nerodia fasciata fasciata) found a sunny spot on a log and allowed for a few pictures to be taken.

Longleaf Pine restoration work in March removed some of the competing oaks.

The view of the same site was quite different this week. Wiregrass grows in bunches, but the grass grows long and lies down over a wider area. Small animals can easily move beneath the drooping grass while benefiting from the cover it offers from predators. When it is time to burn, the wiregrass will allow the fire to carry across the plot.

In addition to the wiregrass, a multitude of native plants are flowering. We will post images in a separate blog once we have identified all of the plants.

Good Walk Spoiled

Mark Twain referred to golf as a good walk spoiled, but today it was the rain that spoiled our good walk across the swamp in Audubon's Francis Beidler Forest.

Once again, we were trying to complete the painting of the cross-swamp internal boundary line. Previously, the futility of painting in the rain caused us to abandon our work. At least then, the swamp was relatively dry and the occasional creek channel was only ankle-deep. With the recent rains beginning to fill the swamp, we knew that we would encounter some deeper water in the creek channels. Additionally, today's high temperature was only forecast to be in the low 50Fs. Based on our wholly unscientific water depth equipment, we report the creek channels as being SOPRANO high!

Although we were unable to complete the boundary painting job, the final creek crossing was more distressing. It wasn't the cool air or the creek's depth, but the fact that we crossed the deep creek just before our lunch break and the rain began to fall steadily as we finished lunch. As paint won't dry in the rain and remain on the trees, we had to head back to the truck, which was on the other side of that deep creek.

As Maxwell Smart was wont to say, "Missed it by that much!"
