Page  3 ï~~2003 THE MICHIGAN BOTANIST THE CHAMPION TREES AND SHRUBS OF MICHIGAN Elwood B. Ehrle Department of Biological Sciences Western Michigan University Kalamazoo, MI 49008 woodyehrle@aol.com This paper is a revision of "The Champion Trees and Shrubs of Michigan" published in The Michigan Botanist 36: 3-29. 1997. Many changes have occurred in the lists of Champion Trees and Shrubs in the five years since that paper was published. Additional species have been included, new champions have been found and regrettably some of our fine former champions have been lost to ice and wind storms, lightning strikes, road commissions, and development. The Big Tree Program of the Michigan Botanical Club started soon after the organization of the club in 1941. Paul Thompson, affiliated with the Cranbrook Institute of Sciences, became the state's Big Tree Coordinator and served in that capacity for over forty years until his death in 1994. Many individuals, mostly Michigan Botanical Club members, worked with Paul over the years as he set about discovering, measuring, and recording Michigan's biggest trees and shrubs. Champion size trees were reported to American Forests, nominated for National Champion status, and subsequently listed in the "National Register of Big Trees," issued every two years by American Forests. I began my work with Paul Thompson in 1991. We had decided to prepare a series of short articles for publication in The Michigan Botanist. Paul described trees he thought I could find, gave me careful directions to their locations, and I began a new set of measurements. About two dozen trees had been located and re-measured before his death in 1994. The series of articles in The Michigan Botanist has continued to grow. As of now, 34 have been published, another two have been submitted, and four more are in preparation. These articles are described in the next section of this paper and listed in Table 1. Paul Thompson had an amazing ability to instantly recall a great many details about each champion tree or shrub and its location. He enjoyed telling me whether the approach road was paved or gravel, whether the farmhouse the tree stood beside had bay windows or not, and, oh yes, "There is a woodpecker hole on the northeast side of the trunk." When I learned of his death, I feared that all of this had been lost. Much of it has, of course, been lost, but not all. Through the kindness of his family and the efforts of friends, George and Kathleen Thomson, his meticulous and voluminous notes were preserved. The notes contained information on 3734 individual trees and shrubs in Michigan. In some cases the measurements were exact and the locations were precise. In other cases, measurements were approximations and locations were described only in cryptic hints. It took two-and-a-half years to sort through Paul Thompson's records. In addition to The Michigan Botanist series of articles, the 1997 paper updating Paul's

Page  4 ï~~THE MICHIGAN BOTANIST Vol. 42 1994 list of champions was published by me (Ehrle 1997) as a result of that work. The four or five largest of each species have been entered into a computer database. There are now 953 individual trees and shrubs in the database. It will not be published, as it is impossible to determine the accuracy of some of the entries. The 227 items in the 1997 list of champions and the 251 items in this paper are subsets extracted from the larger database. This list contains information on 219 current and former State Champions, including 48 National Champions. National Champion status is based on a point system in which the girth in inches at 4% feet above the ground is added to the height in feet and 4 of the crown spread in feet. State Champion status is based on girth alone. Paul Thompson and the people who worked with him discovered most of these champions. Through their efforts, Michigan had more recorded National Champions standing within its borders than many other states. This paper is dedicated to the memory of Paul Thompson and salutes his outstanding contributions to Michigan botany and to the Michigan Botanical Club. THE MICHIGAN BOTANIST BIG TREE ARTICLES With the agreement of the editor of The Michigan Botanist and the endorsement of the Michigan Botanical Club Board of Directors, a series of articles on Michigan's big trees was started in The Michigan Botanist in 1992 (see Table 1). Each article provides a description and illustration of the species along with the location of Michigan's champion, directions on how to reach it, and its most recent measurements. The third paper in this series reports on a tree that has since been lost in a storm. Reprints of these articles are available from me at the address above. TABLE 1.

Page  6 ï~~THE MICHIGAN BOTANIST Vol. 42 HOW TO MEASURE AND REPORT A BIG TREE State Champion trees are determined by measuring the girth or circumference of the trunk, in inches, at 4Y' above the ground. National Champion determination is based on a point system with the number of points obtained by adding the circumference of the trunk, in inches, 4Y' above the ground to the height in feet and Y of the average crown spread in feet. The circumference of the trunk is usually the easiest measurement to make. A tape can be run around the trunk at 4%' above the ground or a string can be used if a long tape is not available. In situations where the tree grows on a steep slope there may be some uncertainty as to just where on the trunk 4%' comes. In these cases, it is best to measure the circumference at 4%' on both the up-slope and down-slope sides and average them together. If a tree trunk branches below 4%', the circumference of only the largest branch should be measured. The height is best determined by using an inclinometer, Abbey Hand Level, transit, or other instrument for measuring the angle formed by sighting the base and top of the tree. If this angle is measured 100' from the tree a table of tangents can be used to convert the number of degrees of the angle to the height of the tree in feet. If instruments to measure the angle are not available you can use a straight stick and back away from the tree to measure its height. Hold the stick at arm's length as you back away from the tree. When you are far enough from the tree that you can sight over your hand holding the stick to the base of the tree and over the top of the stick to the top of the tree you are at a distance from the tree equal to the height of the tree. For this to be accurate, you must be on ground level with the tree base. There are several other more or less reliable methods of measuring the heights of trees. If a tree stands alone and casts a shadow on a sunny day, the length of the shadow can be measured and compared to the shadow cast by a yardstick. For instance, if the yardstick (3') casts a 6' shadow (each foot of the yardstick casts a 2' shadow) and the tree casts a 120' shadow, the height of the tree is 60'. Another method that works quite well is to have someone of known height, say 6', stand at the base of the tree. While you back away from the tree holding a yardstick at arm's length you will reach a point where you can measure the apparent height of the person standing at the tree base and the apparent height of the tree from that point. For instance, if the 6' person measures 6" on the yardstick (1" for each foot) held at arm's length and the tree measures 30", the height of the tree is 30'. For trees standing in a mixed woods where it may be difficult to be sure which top branches belong to which tree and shadows and long lines of sight are not available, the use of an Abby hand-held level, transit, or other instruments may be necessary. In those cases, County Extension Agents, county or city foresters or other experienced person may be of help. The average crown spread can be measured by examining the farthest extent of the crown on all sides of the tree. You then measure the tip-to-tip distance across the largest crown length. Do the same across the shortest tip-to-tip crown distance and average the two. The average is known as the average crown spread. To report a big tree, first determine the identity of the tree. It will not be sufficient to say, "It is some kind of oak," unless you are prepared to send leaves, twig

Page  7 ï~~2003 THE MICHIGAN BOTANIST tips and acorns in with your measurements. Personnel from your County Extension Service or a nearby college or university may be able to help you confirm the identity of the tree. Second, take the measurements described above. If this is not practical, at least measure the girth in inches at 4%' above the ground. Finally, send the name of the tree, its exact location, and measurements to the State's Big Tree Coordinator-for the near future, the author of this paper. This will insure the inclusion of the tree in the state's Big Tree Inventory. It is hoped that GPS records can be included to more accurately indicate the location. You can always find out who the big tree coordinator is for any state in the country by contacting the Director, National Big Tree Program, American Forests, PO Box 2000, Washington D.C. 20013. COMMENTS ON THE LIST OF THE CHAMPION TREES & SHRUBS OF MICHIGAN Much of the information in the list of the champion trees and shrubs of Michigan (Table 2) is self-explanatory. Table 3 presents a list of the abbreviations used. Table 4 presents an alphabetical list of the same trees and shrubs by common names to facilitate finding a tree or shrub when only the common name is known. Table 5 presents a list of these same trees and shrubs arranged by county. The scientific and common names used in these lists are those regularly used in books and manuals treating the plants known to be growing in the Great Lakes area. Important among these are Barnes & Wagner (1981), Voss' three volumes on the flora of Michigan (Voss 1972, 1985, & 1996), Gleason & Cronquist (1991), Dirr (1983), and Rehder (1940). In most cases there is little uncertainty about what name to use. A few, however, are problematic. Most of these are related to hybrids between species or a difference of taxonomic opinion as to whether the varieties of a species should be recognized as separate species. Unfortunately, both of these types of problems occur in our most common trees, oaks and maples. The measurements are given as inches at 4%' above the ground for girth and as feet for height and average crown spread. In most cases these measurements were made in accordance with the specifications given above. Periodically, when a tree is re-measured it is found to have a lesser height or average crown spread. This is usually due to a loss of branches caused by a storm since the earlier measurements were made. The date of the most recent measurement is given in the last column of Table 2. Some of these trees haven't been re-measured in many years. All interested parties are urged to join the search for them and to report their current measurements. The Town column of Table 2 may indicate the city in which a tree or shrub exists or, where more useful, the name of the township is given. For some entries, a state park may be listed or the name of a lake given if it is likely to be helpful in finding the location. Where more than one tree of a given species is listed, it is likely due to the designation of co-champions or situations where the state and national champions are different trees. There are also cases where only the girth is known for recently discovered trees. In these cases the current or past champions, for which complete data are known, are also listed.

In many cases it is both exact and accurate, e.g. a street address or intersection. In other cases, the information is more vague, e.g., near Sleeping Bear Dunes. IMPROVING THE LISTS The three best ways in which the current lists can be improved lie in: 1.) determining if a listed tree or shrub still exists, 2.) obtaining exact and accurate information on the location of each tree or shrub listed and 3.) obtaining up-to-date measurements. It is hoped that users of the list will continue to supply such information to the State's Big Tree Coordinator and that each succeeding version of these lists will be better than the last.
