Even though the arrival of spring is officially not for another two weeks, the change of season is already palpable as wildlife stirs from winter's scarcity, birds begin arriving from southern wintering grounds, and trees begin their spring blossoming. It's likely to be a noisier spring than usual, too, for a rare event is about to take place - the simultaneous emergence of two broods of periodic cicadas, something that hasn't happened since 1803, when Thomas Jefferson was president.


The two broods that will emerge late this month or early in April are known as Brood XIX, which will emerge in the Southeast, and Brood XIII which will appear in northern Illinois. Other broods will take their turn next year, usually just one brood per year, but every 221 years, two broods will emerge at the same time, much to the excitement of entomologists. One such scientist - Charles Marlatt, who worked for the Department of Agriculture in Washington - was the first to standardize brood numbers in 1893, designating all cicadas emerging that year and every seventeen years thereafter as Brood I; those emerging the next year were Brood II, and so on. Cicadas on the thirteen-year cycle who emerged in 1894 were Brood XVIII. It's Brood XIX, first designated as such in 1895, that is emerging in the Southeast this spring.


These harmless insects have an unusual life cycle. Immature cicadas, or nymphs, spend the next 17 or 13 years after hatching underground feeding on roots, emerging from the earth as adults after more than a decade hidden from view. The males are the singers, attracting mates with sound-producing organs called tymbals on either side of their abdomens. Adults don't consume solid food, but subsist on on fluids from leaves and tree bark. Females lay their eggs in the bark of trees, which can be harmful to young saplings but otherwise doesn't hurt mature trees. Cicadas don't sting or bite and are not known to carry diseases harmful to humans.


They are, in fact, beneficial to the ecology. Their underground tunneling aerates soil, and once above ground, they serve as an important food source for birds and other wildlife - and for humans in some cultures, where they're consumed fried or steamed and are said to taste like cold canned asparagus. But if you choose not to partake, you can at least enjoy the singing on a warm Lowcountry spring evening.


March is National Women's History Month. Charleston and the Lowcountry can claim a significant place in the list of pioneering women who shaped the region's social, cultural and agricultural heritage. From Septima Clark's tireless campaigning for equality during the civil rights era, to the Charleston-born Pollitzer sisters' efforts toward women's suffrage, and the Grimke sisters' outspoken opposition to the slave economy during the Civil War period, women have been at the forefront of historically significant changes in in Lowcountry life.

The ruins of Comingtee's plantation house.

Lesser known are women who lived during the Colonial and Revolutionary War years, all the way back to the 17th-century, when Affra Harleston arrived in the Lowcountry from England in 1669. With her family's fortune ruined during the English Civil War, Affra took ship for the Carolinas with a two-year indentured labor contract in Charleston, on the completion of which she was promised one hundred acres of land. A budding shipboard romance with John Coming resulted in marriage and, on her release from her contract, a plantation along the Cooper River which the couple named Comingtee. By the time of Coming's death in 1694, the couple had acquired over 700 acres along the river, part of which was donated for the growing new city of Charles Towne, and which would eventually become the city's Harleston Village neighborhood. Before her own death in 1698, Affra had moved into town, built a house at Wentworth and Philips streets and donated seventeen acres to St. Philip's Church, the beginning of the church's downtown property holdings.

Charleston was home to America's first professional female artist, Henrietta Dering Johnston, who arrived in Charleston from Britain with her clergyman husband in 1706. The couple struggled financially, leading Henrietta to revive an earlier talent for drawing and painting and to build a reputation for society portraits done in pastel. Her commissions took her as far north at New York and saved the couple from penury. She and her husband are buried in the cemetery of St. Michael's Church downtown.

Martha Logan, early American botanist

Martha Daniell Logan, born in 1704 in St.Thomas Parish just outside Charleston, was the country's first female botanist, collecting and exchanging plants and seeds native to the Lowcountry with colleagues in Philadelphia and elsewhere in the colonies. By 1751, she was writing one of the nation's first horticultural columns, The Gardener's Kalendar, for the South Carolina Gazette.

Much of this history has been documented by the city's Preservation Society, itself founded by a woman, Susan Pringle Frost, in 1920 as the Society For The Preservation Of Old Dwellings. And as historian Harlan Greene once pointed out, even the city's official seal and motto, "She guards her buildings, customs and her laws," acknowledges Charleston's debt to her female pioneers.


In your travels along Bohicket or Main roads, you may have noticed red-girded live oaks with a sign saying "Don't Chop Me Down." Given the rampant development on Johns Island, these sturdy symbols of the Lowcountry are, indeed, threatened. We shouldn't take them for granted.


Quercus virginiana is common from (as the name implies) Virginia all the way down the southeast coast to Florida. Ideally adapted for salty soil, humidity and the high winds of the hurricane season, these majestic trees provide crucial food and shelter for wildlife. Deer, squirrels and all manner of birds depend on the southern live oak's acorns during the winter months, while its strong, curving, moss-draped limbs provide ample nesting material and secure nesting sites.


Unlike its deciduous oak cousins further north, southern live oaks retain their leaves nearly all year-long, dropping old leaves as new ones replace them during a short blossoming season in the spring - as we all know while we reach for the leaf-blower from mid-March to mid-April. The trees' crowns, which can grow to as much as a hundred feet in diameter, bestow plenty of shade on sticky summer days; while thick trunks, deep taproots and extensive root systems mean these trees can withstand hurricane-force winds or winter droughts. The wood is incredibly hard and resistant to rot, which is how Old Ironsides got its name. Along with scores of similar naval vessels built during the late 18th and into the 19th centuries, Old Ironsides's hull and keel were built using the wood.


Angel Oak on Johns Island

Southern live oaks are long-lived, with two nearby examples thought to be at least several hundred years old. Johns Island's Angel Oak, just off Bohicket Road near Main Road, is thought be up to 700 years old, with a trunk circumference of over 28-feet and its crown shading an area of 17,000 square feet. Its name comes from prior owners of the property, Justus and Martha Angel, although local legend has it that the floating lights of "angel ghosts" of enslaved African-Americans can sometimes be seen in the tree's upper reaches. The site is now a public park owned by Charleston County.


The Middleton Oak

The Middleton Oak, on the banks of the Ashley River at Middleton Place, may have a smaller diameter trunk, at about 10-feet, but its canopy is truly impressive and served as a landmark and resting place for Native Americans traveling along the river in pre-Colonial times. Some botanists think the tree may be nearly 1,000-years old, still providing cool shade during a Lowcountry summer for modern visitors.
