Environmental Edition, Judy Keenan, Editor Landscape Design Edition, Jane Hersey, Editor Scatter Info As We Bloom and Grow Horticulture Edition, Gail Berthe, Editor Environmental Edition, Judy Keenan, Editor Landscape Design Edition, Jane Hersey, Editor Volume 2, Number 4 Environmental Edition November, 2014 Letter from the Editor November is the month we give thanks for the abundance with which we have been provided. Just as we have been given much, we also have a responsibility to take care of the gifts we have received. What better way to show our gratitude than by the actions we take to protect our natural world. Judy Keenan, Environmental Editor Act for Clean Water By Judy Keenan I remember going to visit Lake Erie as a young child with my family. A tall fence separated us from the water in order to keep people away from the toxins. Wading and fishing were dreams of the distant past. The Clean Water Act, which recently celebrated its 42nd birthday, helped to change that. One of our natural wonders is again fit for swimming. Here in Georgia, the sewage discharge that fouled the Chattahoochee has been reduced by a whopping 99 percent. Wildlife abounds and Georgians can once again enjoy boating and fishing the Hooch. That is progress. Nevertheless, some 40,000 miles of Georgia’s rivers and streams are not protected by the Clean Water Act due to a loophole secured by developers a decade ago. Polluters still dump some 12,621,000 pounds of toxic chemicals into our waterways ever year. In fact, Georgia ranks fifth in the nation for toxic discharge into waterways, according to a 2012 report by Environment Georgia. The Savannah River is the 4th worst river in the United States for toxic discharge, the Chattahoochee ranks 19th nationwide for discharge of cancer-causing chemicals and 14th for release of reproductive toxicants and the Coosa River ranks 14th for releases of toxicants that can cause developmental abnormalities in children and fetuses. As a nation and as a state, we cannot afford to squander our most precious natural resource—fresh water. As citizens, we can ask our leaders to step up to the plate and enforce the laws that are already on the books and penalize polluters. We can insist upon transparency in industry, so we actually know what gets dumped into our waterways. Perhaps even more important, we must stop asking ourselves, “what constitutes a safe level of toxins?” and instead ask “how can we replace poisons with benign alternatives?” thereby eliminating the problem altogether. Botanists Find ‘Holy Grail’ of Georgia Grass By Rick Lavender When it comes to Hirst Brothers’ panic grass, Georgia went from zero to 500--and from potential player to world leader--in one hot August afternoon. A search led by Delaware Department of Natural Resources botanist Bill McAvoy and coordinated with Georgia DNR’s Nongame Conservation Section found an estimated 500 Dichanthelium hirstii plants at a limesink pond in Sumter County on Aug. 7. That marks the first time the candidate species for federal listing as endangered had been seen in Georgia since 1947, and only the DNR Botanist Tom Patrick at the Dichanthelium hirstii site in Sumter County third time ever. “I was very excited,” said McAvoy, of Delaware DNR’s Species Conservation and Research Program. 2 McAvoy is conducting a range-wide survey of Hirst Brothers’ panic grass for the U.S. Fish and Wildlife Service. Previously, there were five known populations of the grass. That includes one plant McAvoy found in North Carolina this year, a population in Delaware and three in the New Jersey pine barrens. Of the sites in Delaware and New Jersey, only one has visible plants this year-- fewer than 20 individuals. Named for two brothers credited with discovering it in New Jersey in the 1950s, Hirst Brothers’ panic grass grows in limesink ponds, or depressional wetlands, that fill with rain in winter and go dry in summer. Thousands of these pools dot the landscape in south Georgia. But many have been altered by land uses such as farming. Others, explained DNR botanist Lisa Kruse, have been overtaken by trees and woody shrubs as the fires that kept the grasslands open have been suppressed. The habitat is also under-surveyed, particularly during the autumnal bloom phase, when the tall grass is more conspicuous. So, while some botanists searched for the plant in Georgia, and many kept watch for it, none saw it. McAvoy returned to Georgia this summer because the state has two historical records of Dichanthelium hirstii--from 1900 and 1947--and the habitat considered key to the plant still seemed in place. (Both collections in Georgia were initially classified as other species, since Hirst Brothers’ panic grass wasn’t described as distinct until 1961.) Prepping for his second trip to the state in two summers, the Delaware botanist scoured aerial photographs and maps for the signature limesink habitat. He crosschecked for sites with Boykin’s lobelia, a rare plant found alongside Hirst Brothers’ panic grass. With Kruse’s help, he focused on where the panic grass had been collected decades ago in Georgia. And on the last day of his search in the field, and at almost the last pond, he and DNR botanist Tom Patrick found it. “It was everywhere, a clump here, a clump there,” Patrick Delaware DNR Botanist Bill said. MacAvoy with a pressed specimen of Dichanthelium hirstii McAvoy said the population at the privately owned 10- acre pond was very healthy. Next steps include discussions with the landowner about possible conservation options, and using habitat details from the site--the plants were found in the draw-down zone of the wet savanna habitat--to fine-tune searches on other property. The effort is worth it, Kruse suggests. “To the best of our knowledge, Dichanthelium hirstii is an indicator of an extremely diverse and healthy ecosystem. Often this species is also with other rare plants … So when you find it, you know that plant community is unique and intact--it’s a special place.” Hirst Brothers’ panic grass has long been a mystery in Georgia, she said. “It’s sort of the grass Holy Grail.” A Grail that has been found.

According to tradition, those first gardeners, Adam and Eve, were “given dominion” over all that lives on our planet. Some have taken that to mean the world is ours to exploit. From the moment Europeans set foot on American soil, land has been seen as a commodity and the vast animal and plant resources there for the taking. There are humans and then there is everything else. But the word dominion refers to authority over something, not ownership of, and to my mind, that entails a responsibility toward protecting what is not ours in the first place. Aldo Leopold, the father of the science of wildlife management, lays out the notion of a Land Ethic in his seminal work, A Sand County Almanac, published posthumously in 1949. Leopold, the son of a manufacturer and a child of the industrialization of the early 20th Century, called for a broader notion of community, asking us to enlarge “the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land.” In other words, we need to recognize ourselves as part of the biodynamic system called Earth rather than mere consumers of it. Leopold witnessed the tragic consequences of overworking the land--Great Dust Bowl. More recently, society has sought to eke more from the earth with industrialized science, using chemical fertilizers, “Round-Up Ready” crops and GMOs. Meanwhile, male frogs are laying eggs, algae blooms suffocate our waters and who knows what the long- term effects to humans will be. In the immortal words television advertising, “It’s not nice to fool Mother Nature.” Tips on How to turn Black Friday into Green Friday It’s almost here—Black Friday, the day blocked out by hardcore shoppers all over America. Here are several ways you can shop with a conscience: 1. Carpool to the mall or, better yet, take public transportation. 2. Bring your own bags. 3. Eschew paper receipts in favor of electronic ones. 4. Buy organic. 5. Buy locally made products. 6. Buy antiques—a nice way of saying used. 7. Buy quality, not quantity. 8. Buy products with recycled content. And above all, remember, Green is the new Black! 4 Scatter Information as We Bloom and Grow is a monthly publication of the Garden Club of Georgia. Each edition focuses on one of three themes: horticulture, the environment and landscape design.

  • INTRODUCTION This Check List of the Plants of New Jersey Has Been
    INTRODUCTION This Check List of the Plants of New Jersey has been compiled by updating and integrating the catalogs prepared by such authors as Nathaniel Lord Britton (1881 and 1889), Witmer Stone (1911), and Norman Taylor (1915) with such other sources as recently-published local lists, field trip reports of the Torrey Botanical Society and the Philadelphia Botanical Club, the New Jersey Natural Heritage Program’s list of threatened and endangered plants, personal observations in the field and the herbarium, and observations by other competent field botanists. The Check List includes 2,758 species, a botanical diversity that is rather unexpected in a small state like New Jersey. Of these, 1,944 are plants that are (or were) native to the state - still a large number, and one that reflects New Jersey's habitat diversity. The balance are plants that have been introduced from other countries or from other parts of North America. The list could be lengthened by hundreds of species by including non-persistent garden escapes and obscure waifs and ballast plants, many of which have not been seen in New Jersey since the nineteenth century, but it would be misleading to do so. The Check List should include all the plants that are truly native to New Jersey, plus all the introduced species that are naturalized here or for which there are relatively recent records, as well as many introduced plants of very limited occurrence. But no claims are made for the absolute perfection of the list. Plant nomenclature is constantly being revised. Single old species may be split into several new species, or multiple old species may be combined into one.

  • Rare Vascular Plant Taxa Associated with the Longleaf Pine Ecosystems: Patterns in Taxonomy and Ecology
    Rare Vascular Plant Taxa Associated with the Longleaf Pine Ecosystems: Patterns in Taxonomy and Ecology Joan Walker U.S.D.A. Forest Service, Southeastern Forest Experiment Station, Department of Forest Resources, Clemson University, Clemson, SC 29634 ABSTRACT Ecological, taxonomic and biogeographical characteristics are used to describe the group of 187 rare vascular plant taxa associated with longleaf pine (Pinus palustris) throughout its range. Taxonomic and growth form distributions mirror the patterns of common plus rare taxa in the flora. Most of the species have rather narrow habitat preferences, and narrow geo­ graphic ranges, but a few rare sp~cies with broad habitat tolerances and wider geographic ranges are identified. Ninety-six local endemics are associated with longleaf pine ecosystems. This incidence is as high as in other comparably-sized endemic-rich areas in North America. A distinct geographic trend in rare species composition is indicated. Species fall into 4 groups: Florida longleaf associates, south Atlantic coastal plain, east Gulf coastal plain, and west Gulf coastal plain species. Distributional factors that produce rarity must be considered in the development of conser­ vation strategies. Overall, conserving longleaf communities rangewide will protect .large ~ numbers of rare plant taxa in Southeastern United States.

    a new plant discovery. The specimen was sent to J.R. Swallen, an expert in the grass family at the Smithsonian Institution, who published a description of this new species in 1961, naming it The Legacy Hirst’s Panic Grass (Panicum hirstii). As early as 1985, David Snyder of Hirst included it in the New Jersey Natural Heritage Program’s list of Brothers’ rare plants as Hirsts’ panic grass (Panicum hirstii) in honor of the brothers who discovered it. It was later Panic Grass renamed Hirst Brothers’ panic grass (Dichanthelium hirstii) by John T. Kartesz in the 1999 edition of Synthesis of the North American Flora. Frank by Kathleen Strakosch Walz always wished that it had been named “hirstiorum,” the plural epithet, for both brothers. Swallen later found an old, mislabeled herbarium specimen that had been collected from Sumpter County, Georgia in 1900. After close examination, he identified it as Hirst Brothers’ panic prass. Subsequent surveys in suitable habitat in Georgia during the 1980s by the Natural Heritage Program and Alfred E.

  • The Flora of Coastal Plain Pond Herbaceous Communities on the Delmarva Peninsula
    The Flora of Coastal Plain Pond Herbaceous Communities on the Delmarva Peninsula WILllAM A. MeAVOY AND PETER BOWMAN Delaware Natural Heritage Program, Delaware Dept. of Natural Resources, Division of Fish & Wildlife, 4876 Hay Point Landing Rd, Smyrna DE 19977 [email protected] [email protected] ABSTRACT. Coastal plain ponds on the Delmarva Peninsula are ecologicallyunique wetlands that support a diverse assemblage of plant species and are a prominent part of the peninsula's natural heritage. As such, conservation of these wetlands is critical in helping to maintain biodiversity on Delmarva. Very little has been published regarding the vegetation associated with Delmarva coastal plain ponds, both in terms of the natural community types and the individual plant speciesthat are closely associated with them. This paper provides a general description of the natural community types, or vegetation zones, found in Delmarva coastalplain ponds and focuseson the flora of the most diverse vegetation zone, the herbaceous community. Particular attention is given to the rare and uncommon flora of these wetlands. The summary of the flora of herbaceouscommunities in Delmarva coastalplain ponds provides strong evidenceregarding their importance for biodiversity conservation on the peninsula. Akin to the well known Carolina Bays of the southeastern U.S., coastal plain ponds on the Delmarva Peninsula (also known as Delmarva Bays or "whale wallows") are a unique type of shallow, seasonally flooded, freshwater depressional wetland. GeIierally elliptical in shape and often with a pronounced sandy rim along the southeast side, these wetlands are typically inundated in the winter and spring and draw down in late summer or early fall (phillips and Shedlock 1993).
