Through my journeys at Tyler Arboretum and discussions with visitors and staff, there is a clear desire by everyone (including myself!) to learn more about what I’ll refer to as Tyler’s spheres – hydrosphere, atmosphere, lithsophere, biosphere, and anthrosphere. Here, I am compiling a list of resources, local and statewide, that may be of interest to those that want to journey in to some literature and videos!
