Mechanical thinning is defined as:

Answer: C. Both (a) & (b)
Explanation
Mechanical thinning selects trees for removal based strictly on predetermined spatial spacing and geometric patterns. This forestry practice operates with little regard for the individual tree position within the crown canopy. Both predetermined spacing rules and geometric patterns define standard mechanical thinning operations. Thinning reduces tree density within a forest stand to promote faster growth of remaining specimens. Mechanical thinning is often applied in densely planted commercial conifer plantations and artificial forests. Unlike selective thinning, foresters do not evaluate individual tree vigor or crown health during this process.
Commercial timber companies use mechanical thinning to cut operational costs in large plantation management. Geometric row thinning allows forestry machinery to navigate dense tree stands efficiently during harvesting. Foresters balance spacing requirements to ensure optimal light interception for surviving canopy trees. Focusing only on spacing ignores the geometric pattern aspect inherent in mechanical thinning operations. Isolating crown position ignores the strict mathematical spacing rules used in this forestry method. Rejecting both valid operational aspects contradicts professional forestry management guidelines and definitions.
