MAP : Study area in Relation to Trinidad
Site Visits
Entry Number- 1
Date – 25th of November 2011
Site Location- WildFlower Park
Objective - To investigate how human activity positively or negatively impacted on the species diversity in WildFlower Park, North-west Trinidad. Activities- At this site we did a vegetation survey, faunal survey soil testing, air quality measurements and slope measurements. * Vegetation Survey- a survey was done of the vegetation at the site. Quadrats were tossed randomly within the site area. The vegetation within each quadrat was counted individually and recorded on our Vegetation Data Sheets. * Soil Testing- within each quadrat we dug up small quantities of the soil using small shovels. We then used our hands to examine the texture of the soil. Then a description of the soil content was recorded on Data Sheets. * Faunal Survey-while examining the soil; the number of organisms seen within each quadrat was recorded. * Air quality measurements- at our site visit we also tested the amount of Sulphur dioxide (SO2) in the air using an air quality metre. The results were then recorded on our Air Quality Data Sheet. * Slope Measurements- the slope of our site area was measured in 1 meter intervals. The results were then recorded on our slope data sheets. Observations- Observations at this site show low species diversity. This was determined due to the small number of organisms found within the site area. We also noticed that human activity was evident as the grass was cut very low there were very few trees and some of which were cut down. Also observed was the location of the park which was right next to a very quiet suburban settlement area. We also noticed that the park was mainly for recreational purposes based on the signs. Comments- based on my observations I can say that the Wildflower Park appears to be a manmade park. There were few trees and a lot of cars which may cause high levels of carbon monoxide. Follow-up Activities- After doing our survey of Wildflower Park we will have to return to our school laboratory and carry out our tests on the soil.
