Beekeeping plays an important role in increasing and diversifying the incomes of many rural communities in Kingdom of Saudi Arabia. However, despite the region’s relatively good rainfall, which results in better forage conditions, bees and beekeepers are greatly affected by seasonal shortages of bee forage. Because of these shortages, beekeepers must continually move their colonies in search of better forage.

The study was conducted to determine the age structure, regeneration status and possible factors for regeneration-gap of Ziziphus population of the southwestern valleys of Saudi Arabia. The population age structure was determined through stem disc ring analysis of fallen trees and girth value measurements of live trees. The average number of rings and annual ring width of trees were determined based on analysis of 95 sampled tree discs and the number of rings correlated with their circumference values.
