Relations of distance from water resources with dryness and pests of Amygdalus scoparia in Baghe-Shadi protected area

This study was conducted initially to investigate the relationship between water resources with dryness and pests effects on Amygdalus scoparia trees in Baghe-Shadi protected area. To this purpose, 17 sampling plots far away from water resources and 17 sampling plots close to these resources throughout the study area were randomly taken. In each plot, the numbers of trees with dryness rate above 25% and also trees affected by pests were recorded. Because of non-normality of data, to comparison far and close areas to water sources, Mann-Whitney test was used. Also, Kriging method was used to draw distribution map of dryness and pests in the study area. Results showed that there was a significant difference between two areas according to dryness, while difference of two areas was not significant for pest affection. The results taken by Kriging showed that the most aggregation of pests in the study area was around the villages and grazing areas.
