COMPARATIVE ANALYSIS:

 

Background Information

  1. Dominance is the measure of the average percent of space a plant occupies in every quadrat it inhabits. It is used to compare the plants which occupy the most space in given quadrats, whether they are different ones or the same quadrat at different times. Importance is the values of relative dominance, relative density, and relative frequency added together. This data is used to determine the overall importance of the individual species to the ecosystem and rank the species. Diversity is the value determined by dividing the total number of species involved in a study divided by the total number of quadrats studied. This value is used to compare the overall health of quadrats.

 

Comparison

  1.  In terms of diversity, the data from the 2005, 2006, and our study are very different. The diversity of plot 17 in 2005 was .94. This year, the overall diversity was 4.8; however, the diversity of the quadrat I shared with Laquita is 10, much higher than the diversities of either plot. In dominance rankings, there is an even larger difference between the studies. In 2005, weeds easily have more than twice the dominance of the native plants with the big bluestem, most dominant native, having 4.38, and the unlisted grasslike, most dominant weed, having 42.60. This year, however, the big bluestem, most dominant native again, has 31.2, while the sweet clover, the new most dominant weed, has 18. The tables have completely turned. For some reason, though, the data from my quadrat leans towards the 2005 data with the compass plant, most dominant native, having 20 and unlisted grasslike having 28. The results in importance are very similar to the results in dominance. In 2005, weeds are much more important, with unlisted grasslike having 172.17 and big bluestem having 70.41. This year, big bluestem had 154.73 and sweet clovers had 129.91.  In my quadrat, unlisted grasslike had an importance of 130.50 and the compass plant had 26.20. These results favor the weeds even more than the results of the whole plot from 2005.

Prediction

  1. Based on the results of the studies of Plot 17 from 2004, 2005, and 2006 as well as the study of Plot 16 from 1992, I would say that in 2016, the native plant population will have less overall diversity, but will be much larger and almost, if not entirely replace the weeds. To support this, there were 23 native plant species and 18 weed species with the weeds having a significant dominance over natives. In 2005, there were 21 natives and 15 weeds and weeds dropping in dominance and natives’ dominance dropping drastically. This year, there were 13 natives and 5 weeds with natives gaining main dominance and weeds dropping even more. At this rate, in 2016, natives will regain complete control of the plot with the big bluestem, compass plant, white prairie clover, and prairie dock controlling the majority and the unlisted grasslike will more than likely represent weeds entirely by itself.

Reflection

  1. From this activity I have learned a lot about prairies and nature in general. First of all, I have learned quite a bit about the various species and families of plants that inhabit prairies. From the rough leaves and sunlight-based leaf arrangement of the prairie dock and compass plant to the sharp leaves of the rip cord grass to the deep roots that most native prairie plants have, I have learned a bit more about how plants adapt to survive in the world. I’ve gained more information on how radically man has changed the environment around the world, as well as an understanding of what Illinois should look like. Moreover, I have learned of another area of the world I like to explore. Most surprising and important of all, I now realize how fast native plants can regain their lost habitats if given help from humans. Overall, this study of prairies has reinforced my belief in restoring nature to its former self so man and the rest of nature can coexist.
