Unformatted text preview: Megan Carter GEO 221 Regional Physical Environments October 18, 2010 Individual Reflective Essay According to Vankat and Snyder (Floristics of a chronosequece corresponding to old field-deciduous forest succession in southwestern Ohio) sites of differing ages but similar settings actually differ greatly in terms of taxa, common species, and diversity of the ground layer. They studied a 2-year, 10-year, 50-year, 90-year, and old growth forest. They found that that highest number of taxa, common species, and diversity in the ground layer were all in the 50-year old site. This is an example of how age makes a difference in ecology. At the beginning the field begins to be overcome with invasive species, then as time passes it gives time for seeds to be dropped by birds, brought by the wind, or by creek and for insects to begin pollinating and larger more time-needing plants (such as trees or larger shrubs) begin to grow. Then, in the middle growth stage (such as the 50-year plot in Vankat and Snyders findings) it seems that...
