The graph below presents the number of borer beetles per hectare in relation to the size of the forest cover.
As we can see, the number of borer beetles increases with the percentage of forest cover. At 15% of the forest cover the number of beetles is around 4 per hectare and at 30% it would be around 11, showing a
275% increase in number.
Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.
Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.
