Additionally, the beaver's feeding activity often girdles trees as it eats the cambium layer, which is the living tissue that connects the tree's leaves to its roots. Girdling the tree breaks that connection and prevents the tree from manufacturing and storing food, which leads to the tree's death. Naturally, the managers of Beidler Forest were concerned about how dead and dying trees along the boardwalk might affect a visitor's experience. Thursday, November 15, 2007

Master Naturalists
From the Master Naturalist webpage: What is a Master Naturalist?
A Master Naturalist is a person who has undergone specific training and who regularly volunteers time toward various projects. Typically, Master Naturalists seek to make a difference in helping to maintain the quality of our native ecosystems through training designed to help ‘read’ the landscape of the state. This includes understanding the underlying geology, specific inhabitants (birds, plants, mammals, etc.), ecology and the impacts of humans on the landscape including how we conserve our amazing natural environments. Once trained, Master Naturalists volunteer in a variety of projects. In essence, the Master Naturalist program aims to turn out volunteer citizen scientists who can positively impact the natural resources of the state.
While learning about the geography and characteristics of the swamp, the participants were also practicing the tree and plant identification skills they had learned during previous field trips. The images show the group once it moved from the boardwalk to the bluff overlooking Mallard Lake, which is approximately two miles downstream. The high bluffs have underlying limestone near the surface giving rise to a plant community called the calcareous forest.
From Richard Porcher's and Douglas Rayner's A Guide to the Wildflowers of South Carolina: The calcareous forests occur on bluffs, slopes, or moist flats that overlay calcareous substrates. The substrate is either marl or limestone that was laid down as marine deposit when the ocean covered the coastal plain. The calcium from the underlying substrate is a major factor shaping the diversity and composition of the vegetation. Certain species of plants, referred to as calcicoles, thrive in a basic to circumneutral soil that results from the presence of calcium ions. These species generaly are mixed with the flora of the surrounding community to form a diverse community. Classification of the various calcareous communities is not well developed; however, we do recognize two well-developed types. (One is the calcareous bluff forest which the group visited at Mallard Lake).

Evening Roost
where near the Waterwheel Fishing Lake, they appear to head for the two cypress trees growing in the middle of the pond. They don't have the benefit of our Global Positioning System (GPS) or Google Earth, but they find their way there every evening. If in Google Earth you type 279 Water Wheel Drive, you will zoom right to the pond. The image shows the two trees in the middle of the pond, in which the birds are roosting.Friday, November 09, 2007
Poisonous or Not
Is the snake in the image a poisonous or non-poisonous one? Pat yourself on the back if you said, “Neither.” There are no poisonous snakes, only venomous snakes. Next question, “Is the snake in the image a venomous one or not?”
How does the safety rhyme go? “Red on yellow can kill a fellow…red on black a friend of Jack.” The only Jack we know is deathly afraid of spiders, so we don’t think any snake will be a friend of his. Maybe the rhyme is, “Red on yellow is a friend of a fellow…red on black means take a step back.” Frankly, we can never remember the rhyme when we are safely in our office, so we doubt that we’ll remember it when faced with possible death! We prefer to keep it simple and use brain cells already filled securely with useful safety information. When you are driving and the light is yellow, you know that the next color will be red and that means stop…even if you thought the correct answer was “mash the accelerator.” Therefore, if the snake has yellow next to red, STOP! This would be the venomous Eastern Coral Snake (Micrurus fulvius). As you can see, the snake in the image has red next to black, so it is the non-venomous Scarlet Kingsnake (Lampropeltis triangulum elapsoides), which is a subspecies of the milk snake.
Scarlet Kingsnakes are secretive and rarely seen crawling about during the day. They are active at night, and spend the day hidden below ground or behind the bark of trees, so their bright colors are not a liability. These snakes eat mostly lizards, especially skinks, but will also eat small snakes and rodents.

A Sand County Almanac
A Sand County Almanac written by Aldo Leopold and published by the Oxford University Press in 1949 is a wonderful read for anyone that enjoys the natural world. Aldo Leopold was a founding member of the Wilderness Society and is credited with founding the profession of game management.Friday, November 02, 2007
Harvesting Wiregrass Seeds
Five volunteers joined Collis Boyd and Norman Brunswig, Audubon South Carolina staff at the Francis Beidler Forest, to harvest seeds from Wiregrass (Aristida stricta) for replanting on other Longleaf Pine (Pinus palustris)/Wiregrass restoration sites.
The tract harvested today will continue to be a seed nursery for other Longleaf Pine/Wiregrass restoration projects. One team cut the seed heads off of the Wirgrass while the second team applied herbicide directly to invading hardwoods.In a mature Longleaf Pine ecosystem, hardwoods would not get a foothold due to the periodic fires that burned through the forest. The fires would consume the pine straw and kill the hardwoods that are not adapted to fire like the thick-barked Longleaf Pines. However, the slower growing Longleaf Pines do not grow quickly enough to establish a Longleaf Pine forest before hardwoods can establish dominance. This is why the native Longleaf Pine forests did not reestablish themselves once they were clear-cut by European settlers and later by lumber companies in the 19th and 20th century. Additionally, cleared longleaf stands were replanted with faster-growing Loblolly Pine and Slash Pine. Audubon South Carolina, along with other private and governmental agencies, contine to work towards restoring the native Longleaf Pine forest with its associated plant and animal communities.

Fly Like a Bird!
Jeff Mollenhauer, Director of Bird Conservation, has been a busy man this week! He reports on his bird's-eye view:
wetlands or "gum ponds" that are found througout the East Edisto area. These small wetlands are scattered like tear drops amidst the pine plantations and clearcuts. These isolated wetlands serve as important areas for many species of ampibians and reptiles, as well as Audubon WatchList species such as Wood Thrush, Prothonotary Warbler, Kentucky Warbler, and Swainson's Warbler. Finally, we flew over some corridors of older lobolly pines which looked like good habitat for WatchList species such as Brown-headed Nuthatch and Bachman's Sparrow.Wednesday, October 31, 2007

Mercury in SC Fish
The coal-burning power plants in our region contribute greenhouse gases that cannot help cool an atmosphere that is undoubtedly warming by whatever means, natural or human-induced. Additionally, the coal-burning power plants are introducing high levels of mercury into our environment. The desire to build additional coal-burning power plants in our state is driven by the increasing demand for electricity.
As citizens of South Carolina and stewards of our environment, we need to acknowledge our part in this issue and take ACTION to reduce our negative role. There is no shortage of webpages or resources, both governmental and private, that provide information to help consumers reduce their energy consumption. Many of the common-sense suggestions can be easily and painlessly instituted. Additionally, citizens need to contact their local, state and federal representatives as well as their power provider and demand that technological upgrades be applied to reduce the harmful emissions from coal-burning plants. These demands should be made with the understanding that the upgrades will come at a cost to the consumer. However, any increase in the cost of electricity per household can be offset by a reduction in consumption and we all benefit! Even inaction has a cost (poisoned waterways, poisoned fish, poisoned family members, increased health care, etc.) and it is infinitely less pleasant than a few pennies per kilowatt/hour.

Caterpillars

the Pale Tussock Moth (Halysidota tessellaris), which has the black tussocks (hair-like projections);
and the yet-to-be-identified orange caterpillar, which appears to be a type of dagger moth. Soon these caterpillars will create a cocoon (or a chrysalis if they are a butterfly) and overwinter in anticipation of their metamorphosis to a flying adult in the spring.Thursday, October 25, 2007
GLOBE Training
On October 30th, Audubon at Francis Beidler will become a U.S. GLOBE partner and Director of Education, Mark Musselman will become a certified GLOBE trainer. The GLOBE Program (Global Learning and Observations to Benefit the Environment) is a worldwide hands-on, primary and secondary school-based education and science program that unites students, teachers, and scientists from around the world in study and research about the dynamics of Earth’s environment. Over a million GLOBE students in more than 19,000 schools located in over 100 countries are taking important environmental measurements, using their data in their own research and also making it available to scientists around the world. Over 16 million student measurements are recorded on the GLOBE Web site!The goals of the GLOBE program are:
• To enhance the environmental awareness of individuals worldwide.
• To increase scientific understanding of the Earth.
• To improve student achievement in science and mathematics.
Many of the GLOBE measurement are part of ongoing scientific investigations selected through the National Science Foundation’s peer review process. Scientists have developed measurement protocols and instrument specifications to ensure that the data collected by the students are accurate and consistent. Investigation areas in which students collect data are: atmosphere and phenology, hydrology, land cover/biology, and soil. Students use global positioning system (GPS) receivers to accurately locate all sites where they collect data. There are several measurements conducted under each investigative area. Many scientists and their teams continue to review GLOBE data reports in the archive for use in their research as well as for quality control purposes.
GLOBE is an interagency program funded by the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF), supported by the U.S. Department of State.
As a U.S. GLOBE Partner, Audubon at Francis Beidler Forest will recruit teachers into the program, provide training for these teachers so that they may teach students to carry out GLOBE investigations and data collection in a consistent and accurate manner agreed upon by the international environmental science community, and help provide teachers and their schools the support and guidance they need to ensure the sustainability and growth of the program in the years to come.
We will do this by implementing GLOBE protocols during school field trips to Beidler Forest, during summer camps, and during teacher-training workshops hosted here in the swamp.

Trashy Attitude
What is it about some middle school children that compels them to throw their nametag into a hollow stump as James did, or write their name on the sink cover like Miss Green did, or carve their name into the boardwalk like Lulu did, or transfer wrappers from their candy directly to the swamp?
We don't have any answers...only questions. However, when you work at a place like this, it is difficult to win the sympathy of others when trashy individuals do not respect or appreciate the uniqueness of this unmolested, old-growth swamp. We can always take a walk beneath its canopy, enjoy the peace, and wonder at the diversity of life within reach of the boardwalk.

Old Cypress
Last week, a class of students from Eastern Kentucky University visited the Audubon Center at the Francis Beidler Forest to study the trees in the cypress/tupleo forest. The image shows Erin Reno, seasonal naturalist, standing next to a Bald Cypress (Taxodium distichum), which is listed as the second oldest Bald Cypress in eastern North America. The tree has been cored showing it to be 1246 years old, but as with many trees in the swamp, this tree is hollow. Extrapolating for the hollow inches, we estimate the tree to be over 1500 years old.The list of the oldest trees in eastern North America can be found here. The list of the oldest Bald Cypress trees can be found here. Although the University of Arkansas Tree-ring Lab data only shows the oldest trees for each site, we have the notes taken during the actual coring at the Francis Beidler Forest. There are several trees directly off the boardwalk that are over 1000 years old.
Old-growth...there's nothing better!

Fungus Amongus
With the help of the current seasonal naturalists, we intend to catalog all the fungi that we can find. It will take some work because there is a whole lot of fungus amongus! We're thankful for the fungi because without it we would be buried beneath leaves, limbs, trees, and other organic material that accumulates daily on the forest floor. Fungi are part of the decomposer army that helps recycle nutrients back into the forest food web.
The images show a sample of the cataloging effort. The "toadstool" shows a Southern Toad (Bufo terrestris) next to the edible Russula xerampelina, which seems to be a favorite food for rodents, including squirrels. The blue fungi is Milky Indigo (Lactarius indigo), which is also listed as edible. Note to staff: Send memo to George Carlin regarding his statement that there is no blue food.
We would need the help of an expert mycologist with double five-star qualifications before we dine on any swamp fungus. The final specimen would never tempt us, but it sure attracted a crowd of insects. It smelled like a cross between a rotting carcass and something worse.
We haven't identified it yet, but we quickly came up with several unprintable common name suggestions.Photos by: Nicomas Dollar Red Horse

Wetlands Reserve Program Dedication
The WRP easement will restore and permanently protect over 6,000 acres in the forest thereby adding an additional layer of protection to the Audubon property. The WRP plan will restore the natural hydrology to original pre-development conditions, before the construction of logging roads altered it. The large high-fill roads altered the hydrology by forming what amounted to dikes across sections of the floodplain. These roads were constructed to get at the valuable cypress trees deep in the swamp and were formed by piling up the spoil collected from the swamp floor alongside the road's path. Alligators now use those road-side, water-holding depressions when water is scarce elsewhere in the swamp.
