Jackson Big Trees


Why the Search?
Why Audubon?
Jackson Audubon has long been involved in promoting an awareness of the importance of trees in our lives. The reasons are obvious. Trees provide birds, Audubon's main focus, with food, nesting sites and protection from both predators and the elements.

Trees also provide man with a wide array of materials that improve our quality of life: wood with which to frame our houses, build our furniture and, for some, heat our homes in winter. The leaves of trees take in carbon dioxide and in turn give off oxygen, thus filtering the air and providing man with one of the essentials of life.

Trees provide shade in the summer, visual wonders in the fall, wind breaks in the winter and flowers in the spring. It is any wonder then that we seek to find, protect and preserve these special friends of ours?

We urge those visiting this web site, whether a member of Audubon or not, to join us in our annual campaign that dates back to the 1970s. Help us find, nominate and confirm the largest trees of each species in Jackson County.


How does someone interested in the Big Tree Search become a part of the county-wide effort to find those special specimens of the many species found in southern Michigan? Overcoming inertia (in other words, getting moving) is probably the biggest obstacle one has to overcome. We suggest three relatively easy steps to get started.

Start by examining the trees in your own back yard (you might be surprised). Do a little reading of basic references on the trees of Michigan (both books from the library or a search on the Internet will suffice).

Take a personal tour: 
On a sunny day, a walk around your block will bring into focus dozens of new tree discoveries if your eyes are really open and your mind receptive. Jackson Audubon can also provide a list of all county champion trees on public lands. Some are undoubtedly within a short distance of your home.

Make contact: 
Getting together with others who are interested in the search is probably the single most significant way to really get involved. Join Audubon! Membership applications are available here.

Copper Beech

Jackson County's state champion Copper Beech, only recently fallen due to disease and a lightning strike, originally occupied the front lawn of the St. Joseph Orphanage on Blackstone Street.


This county champ Redbud makes a brilliant show of color in spring in front of the Carnegie Library in downtown Jackson.

Amur Honeysuckle

An unusual species from Asia, the Amur Honeysuckle is located in a private backyard in Jackson.

Silver Maple Plaque

Jackson Audubon places brass plates on public champion trees if the tree is healthy and large enough. In this case, a venerable Sugar Maple in eastern Jackson County is so honored.

American Sycamore

This American Sycamore, fourth largest in the county, is a special guest in the front lawn of a home in Jackson.

Black Oak

This large Black Oak can be found in the backyard of a rural home in the county.
