Month: June 2018

I’m continuing where I left of with data collection; today I managed to collect data for tree height and tree diameter under different classes. I also managed to download data from the HPV (Heat pulse velocity) to show how much moisture has evaporated through the trees and the AWS (automated weather station) that I will use to formulate graphs of rainfall patterns,humidity, daily  temperatures and wind speed . To know the impacts invasive alien  species have on groundwater recharge, I will have to check how much water has been depleted by the trees and how much they have grown in a period of two months.

Today I took a field trip with my CSIR Host Supervisors to Conduct field experience in the installation of sap flow sensors to measure transpiration (water use) of trees. We also measured an area of 10m x 10m, Calculated how many invasive alien  trees are found in that area and also measured their stem diameter. The reason for measuring the stem diameter is to check how much the invasive alien trees will grow starting from today (07/06/2018) and compare that data  with the one that will be  collected in a month’s time. It was a very informative experience today of drilling the trees at a certain length and inserting the sensors.
