The mountain pine beetle is more likely tofly first in Forest B.
Forest B has optimum conditions to support and meet thecriteria for the mountain pine beetle to start flying early. The mountain pine beetle is going to have ahigher chance of flying earlier in favourable surroundings, such as having highlight intensities, low wind speeds and high air temperatures (stated in scenario).Forest B seems to get more exposure to sunlight as on July 1st thecloud cover is 57%, but by July 6 it decreases to a mere 2% (stated in scenario).The mean of the cloud cover is 18% throughout the days which means there ishigh light intensity. Making it an ultimate site for the beetles to fly early. This increases the chances of a beetle inForest B to start flying ahead of a beetle in Forest A. Mountain pine beetles cannot withstandwinds greater than 7km/hour and will not fly if winds reach that point (statedin scenario). Forest B has winds 7km/hour or lower during most days.
Other thanthe exception of the first two days, with gusts being 8km/hour and 9km/hour. Thebeetles prefer to fly in low winds, which makes Forest B an impeccable locationagain for the beetle to begin flying earlier. Temperature can significantly affect the efficiencyof the mountain pine beetles flight. The beetles will not fly in temperatureslower than 19 degrees Celsius (stated in scenario). In the first two days,Forest B temperatures range from 10.
9°C – 15.3°C, while after that the temperatureis ranging from 19.2°C to 30.7°C. However, in Forest A the cloud cover percentageis quite prohibitive for the beetles. As it ranges from 15% to a high of 77% throughoutmost days. Though they can also fly in low intensities, it is not an idealsetting for them.
Likewise, mountain pine beetles also require winds lower than7km/hour in order to fly. Nonetheless, Forest A’s wind speeds exceed the 7kmlimit on every single day, except for July 6 when it is 4km/hour. This restrictsthe flight of the mountain pine beetle for the first 5 days making it very hardfor them to start flying. Consequently, low winds, higher temperaturesand high light intensities are all conditions in which the mountain pine beetlecan thrive in. Therefore with all the evidence provided, Forest B seems likethe ideal environment for a mountain pine beetle to start flying first and soonerthan a beetle in Forest A.
