I left for vacation to the Outer Banks for the week, and unfortunately I was not able to return to Iuka Park to photograph additional plants for this post. I will be back to campus to photograph and replace these species with pictures Sunday evening, June 6. However, this update will describe 4 plants with high and low values for coefficient of conservation. Coefficients of conservation range in value from 0 (plants with a wide range of ecological tolerances), to 10 (plants with very narrow tolerances).
Some plants that can be found in Iuka Park but have low coefficients of conservation include the sugar maple, with a coefficient of 3. The bitternut hickory still has a low CC value of 3, but is approaching the region of less tolerant plants. Dog-rose is the most tolerant so far, providing a coefficient of conservation of 2. Just like the dog-rose, another plant that has a CC of 2 is garden phlox, Phlox paniculuta. The first plant that I found with a high CC value was the Northern blue flag iris, which had a value of 6. The Virginia iris is also found in Iuka, and also has a high CC value of 6. The sweet birch, Batula lenta can also be found in the park, and has a described CC value of 7. The final high CC plant, the Shagbark Hickory, offers a value of 6. I will make sure to have original pictures of these plants taken and uploaded as soon as I return from my trip.
