an investigation to estimate and compare the population size of buttercups in a field in direct sunlight and a field shaded by tree cover.
Method:
-
- Place a tape measure onto the ground with the starting end placed at the base of the tree trunk. This creates a transect.
- Place the quadrat at the start of the transect and record the amount of squares within the quadrat that have buttercups in them.
- Using a light meter, measure the light intensity at this position of the quadrat (measured in Lux).
- Repeat this process, recording the amount of squares with buttercups in and the light intensity at this area.
Either a belt transect or a interrupted belt transect can be used for this investigation
Belt transect: this is there the quadrat is placed next to its previous position with no spacing in between.
interrupted belt transect: this is where the quadrat is placed at intervals along the the transect (this allows more distance to be covered.)

Risk assessment
Wet conditions: Could slip and cause an injury - to remove this hazard, check the area before hand and wear appropriate foot wear
Hazardous area: there could be dangerous materials like potential broken glass or other issues - to remove this check that the area is safe before hand.
allergies (and infection) : allergies and infections from foreign particles and bacteria outside - to remove this wash hands thoroughly after completing the practical.
