Erythronium Newsletter of the Iowa Native Plant Society vol. 16 no. 3 December 2010 Plea from a Sister Society: Don't Use Cypress Mulch storks, limpkins, several types of owls, opossums, bobcats and wood ducks. • You can help save cypress forests by using environmentally friendly mulch. Switch to Why kill a tree to grow a flower? That’s the question alternative mulches for your home and a Florida Native Plant Society chapter is asking in its business landscaping, and ask your friends brochure urging people not to use cypress mulch.(The and county government to do the same. If brochure can be downloaded at http://suncoast. you don’t find alternative mulches at your fnpschapters.org/pdffiles/mulch.pdf.) garden supply store, enlighten the manager and request alternatives. The next time you’re tempted by the stacks of Alternative Mulches cypress mulch available at the gas station or garden supply store, consider this: Recycled Yard Waste: Mulch made by your county or city from recycled urban plant debris • Thousands of acres of cypress are logged every year from Florida’s native wetlands simply to is inexpensive or even free in some areas.

Cypress mulch used to be produced locate your closest source, contact your Solid Waste Department or County Extension mainly as a by-product of lumber operations, but the increasing demand for mulch has led to the use Service. of whole trees—whole forests—for nothing but Hardwood Mulch Made of shredded bark mulch. left over from milling hardwood trees such as maples and oaks, this sturdy mulch compacts • The idea that cypress is superior to other over time so it resists blowing or washing away. mulches is not true anymore. The old-growth [reprinted with only slight editing from INPAWS Journal – The Newsletter of the Indiana Native Plant and Wildflower Society, Autumn 2010 issue, pg. 16] cypress harvested prior to the 1950s had a reputation for being rot- and termite-resistant. But those trees have all been taken except for the few saved in Florida’s nature preserves (they can live up to 1500 years and grow up to 150 feet tall and 25 feet in girth). It takes hundreds of years for a cypress tree to grow the heartwood that used to have those properties. The young cypress that are harvested today are not decay or pest resistant and do not make a superior mulch. • Florida’s unique cypress forest is a treasure with an important ecological role. It naturally filters pollutants and serves as a reservoir for floodwater, so it is essential for protecting the ground water. It provides prime habitat for woodpeckers, wood continued page 9...

Leaves of the President's Notebook... Spring Break On Saturday afternoon during Memorial Day weekend, I lost my balance while on a trail in Badlands National Park. In the time it takes to read this sentence, I’d hit the ground and recalled a similar spill on Alaska’s Matanuska Glacier. That fall had merely resulted in a bruised thumbnail. The crack that I heard during this descent, however, indicated that my lower right leg was broken. Fortunately, I was with students and other faculty. A cell phone was used to call 9-1-1. Fortunately, we were not very far from the vans and NPS help arrived quickly. With my leg secured in a splint, a few students assisted members of the local fire department to carry me to a waiting ambulance. In Rapid City later that evening, I underwent surgery to repair the damage. By noon the next day I was heading home. I devoted the subsequent summer (and part of the autumn) to recovery. Whereas I would be restricted in most activities, I resisted being overly limited (as well as defined) by my injury. I did not drive while my leg was in a cast, yet still had a great time leading a 10-day student trip around Puget Sound at the beginning of June. Destinations included Mt. Rainier, Mount St. Helens, and the Olympic Peninsula. Naturally, my hiking was limited, but I saved some energy to walk (with crutches) through the Hall of Mosses in the Hoh Rainforest. Although I was out of the cast in time for the North American Prairie Conference, I still relied on those crutches at the meetings and in the field. Lately, walking has become relatively effortless and I’ve spent a month regularly commuting to campus on my bicycle. On the whole, my accident (with its subsequent recovery) has been a minor inconvenience. The ordeal has been less of a burden in part because I’ve benefited from many acts of kindness – unexpected rides, doors held open, words of encouragement. I now have a personal appreciation for both handicapped parking and the wheelchairs provided by museums, visitor centers, and airports. In part because I cannot personally thank everyone who helped during my recovery, I will be among those who encourage others with similar injuries. Brian T.

This is very exciting! Everyone went home with a high-quality insect collection and preservation kit and a binder with information to help them continue learning and identifying insects. Our hope is that we’ve instilled a new or renewed awareness, excitement and admiration for the insects around us!

INPS Award to Connie Mutel Connie Mutel (center) was honored at the 2010 Iowa Native Plant Society Annual Meeting at Timberhill Oak Savanna on September 11, 2010. INPS recognized Connie for her dedication and contribution to INPS and for all she has done for native plants and Nature in Iowa through the books she has written and edited. Presenting the award for INPS was Dianne Blankenship (left), board member from Sioux City. The award was a framed photo created by Robert and Linda Scarth (Linda is on the right), selected from their book, Deep Nature: Photographs from Iowa.

What's next? On November 2, a clear and overwhelming majority of Iowa voters (63%) declared their support for the values behind Iowa’s Water & Land Legacy amendment. This resounding “YES” vote creates the Natural Resources and Outdoor Recreation Trust Fund, which will provide for clean water, soil conservation and restoration of wetlands to help prevent future floods. This new trust fund is not yet funded. But now we're certain that the first share of any future sales tax increase will support Iowa's natural resources. It is premature to talk about if or when that will occur. In the meantime, we're exploring interim funding options. This vote made another major impact — by surprising the political pundits and candidates about the true breadth and depth of Iowans’ support for conservation. Voter support was broad and bipartisan. The Iowa’s Water and Land Legacy coalition included over 130 organizations representing more than 300,000 members. We are a coalition of “jeans and suits, tennis shoes and waders, and camouflage and blaze orange.” You, the voters, have shown that Iowans DO care about our land, water, soil, wildlife and special places! You've said, "This is a priority for action and funding." Let's express those values more often! Help maintain the flame of this election victory by regularly reminding others - particularly your elected officials - that Iowans must protect our precious natural resources. Thank you for your vote and your voice! Yours in conservation, Mark C. Ackelson President Iowa Natural Heritage Foundation 8 Gladys Black: The Legacy of Iowa’s Bird Lady Gladys Black’s newspaper columns about birds and birding, her environmental education work with young people, and her high profile as an outspoken defender of the environment made her well known across Iowa. And, despite her death in 1998, Gladys’ influence still touches many people. That legacy prompted Jon Stravers and Larry Stone to keep Gladys alive with their recent book, Gladys Black: The Legacy of Iowa’s Bird Lady. Stravers, who now works for the National Audubon Society on the Upper Mississippi River, first met Gladys in the mid-1970s, when he called Gladys with a question about a screech owl that was nesting near his home. She encouraged his interest in birds of prey, introduced him to other birders, and set him on a career path as a raptor researcher and conservationist. Stone worked with Gladys when he was outdoor writer/photographer for the Des Moines Register and she was contributing birding columns to the paper. He regularly contacted her as a source of information about birds. Their relationship continued throughout her life. In 1976, when Stone was writing a series of stories about canoeing Iowa rivers, Gladys urged him to contact Stravers, who often watched birds from his canoe. The men have remained friends and associates ever since. In 2003, they teamed up to publish Sylvan T. Runkel: Citizen of the Natural World, which is a biography of another conservation legend. For the book about Gladys Black, Stone and Stravers interviewed dozens of Gladys’ friends, continued from page 1... neighbors, adversaries, and associates.
