The Rocky Road to Plant Diversity in Michigan @ Chippewa Nature Center, Midland

February 4 @ 7:00 pm - 9:00 pm

Rocks form the structure on which all life on earth exists, shaping the topography and, in most areas, directly influencing the soils. Michigan, by worldwide standards is flat and recently glaciated, so this direct connection is largely broken. Lack of elevation means that rocks directly influence plant growth only where exposed, not by affecting topography (as in mountainous regions). In addition, deep layers of glacial deposits mean outcrops are limited. However, rock exposures that do exist have a very strong influence on plants resulting in some of our most interesting natural areas. More subtle indirect influences on the flora include bedrock as sources of glacial deposits, and subtle topographic influences beside mountains – river valleys, the Great Lakes basins, etc. – shape the flora occurrences, mostly by channeling or blocking migrations of plants into the region. We will have a look at how these direct and indirect influences shape the native flora of Michigan that we see today.
