EVS-Lab quadrant study Essays

EVS-Lab quadrant study Essays EVS-Lab quadrant study Essay EVS-Lab quadrant study Essay The main findings of this study of vegetation in Terrace and Forest are that this sensitive environment is intricately balanced by the maintenance of its vegetation. Based on the readings above we are able to identify that vegetation levels in Area 1 i. e. Terrace is much higher than Area 2 i. e. Forest. One of the sole reasons to this can be, Sunlight-Since plant can absorb more sunlight in Area 1 since not many Trees are blocking sunlight for plants and grass unlike in Area 2 where plant growth is very limited due to blockage of sunlight. This factor will affect plant growth thereby Vegetation. Continuous harvesting of plants and grass in area 1 has lead to higher vegetation levels present there unlike Area 2 where Major parts of quadrant were covered with dry soil, twigs and leaves were an evident factor to conclude lack of harvesting in Area 2. Presence of many plants in Area 1 is another indication of a typical health land vegetation. Major Component covered with Dry soil served as a factor to low nutrient in soil in Area 2 rather than in Area 1, where minor dry land was discovered. Therefore findings conclusion of this vegetation study is that relationship between the vegetation of the two areas (Forest Terrace) is influenced by external factors such as soil harvest and environmental factors such as sunlight. Therefore Area 1(terrace) has a much healthier Vegetation compared to Area 2(forest). Evaluation: From our research and findings on this experiment we have discovered that Area 1(Terrace) has a much healthier vegetation compared to Area 2(forests). However based on the data collection processing,Pattern or relation with Vegetation level with both the areas are very limited. However during the experiment there were many limitations:   The field work investigative tests were carried out by small groups of students. This could have distorted the findings as techniques may have varied been inconsistent. Each group was made aware of what how the data needed to be obtained to keep it as consistent as possible. Time limits on the data collection may also have meant that there was less accuracy in the other recorded results. Although trouble was taken to correctly label samples record data, the sample station data from 25 metres became contaminated by human error. This meant that no comparison could be drawn from these stations. This could have been avoided if there had been a less pressurised time limit to the field work tests. * Experiment being carried out once ,may have lead to less accurate results for the vegetation study. Transect study being carried out on one area rather on two different areas may have distorted results.   Testing vegetation levels only by the means of transects quadrants, means testing methods were very limited Therefore these steps can be carried out to to improve the experiment and obtain results more specific and accurate: Larger groups of students may be utilized to keep results as consistent as possible and improve results.   Time can be increased for data collection to collect sufficient data to improve accuracy. It would also be interesting to see, if experiment could be performed repeatedly at different times of the year and observe if any changes in vegetation levels occur and make comparisons. Rather than the transect study being more fixed to one area, it can be studied for two areas rather than two sites at one area. By implementing this method comparisons can be made and result for vegetation level may improve.   Besides employing transect quadrants to study vegetation level, Tests on soil such as pH, moisture content may be conducted to make comparisons with vegetation and soil of the areas.
