Line Transect definition:
A line transect is a straight line or narrow section through an object or natural feature or across the earth's surface, along which observations are made or measurements taken. It is a method of sampling. The belt transect method is similar to the line transect method but gives information on abundance as well as presence, or absence of species. Belt Transects can be used to measure a species or species of flora or fauna, or other data like human impact etc. You can combine the transect method with other fieldwork tools, such as taking quadrat data, or abiotic/soil data at different points along the transect line to establish links between changes in vegetation and soil, air characteristics.
For this data collection, on 5th May 2020 we entered Brunswick Heads Nature Reserve. We constructed a line transect that goes East from Simpson Creek in a line towards the beach. As such it passes through an example of endangered Littoral Forest.
To create this transect DEEC:
measured out 50 m using a tape measure - East from Simpsons Creek towards the beach.
placed a transect pole along at 10 metre intervals starting with 1 in the Riparian Zone (area alongside a waterway).
took 360 photos at each of the 5 x10 m intervals.
took photos/videos of signs of life along the transect.
Your task is to work in each of the 10 metre lots along the transect line collecting data. This task correlates to page 7 in your work booklet
The plants chosen to collect data on are:
