The different elements of climate can affect natural plant. Every type of plant has definite climatic environments that helps its growing. Climate has a prime role and an obvious effect on the ecological variables and the participation in the rareness and availability of water which is the main resource of plant growth as well as the increase of vaporization and temperature and other climatic elements. Climate is also an effective factor in the natural plant in the dry and semi-dry areas as well as humid areas as represented by temperature, sunlight, fallings, wind, rains. All those factors have an important and effective role in the distribution of natural plant. The position of Diyala Province is in the range of tropical warm latitudes in the northern hemisphere. This what makes its climate transitional between the desert climate and the Mediterranean climate which is a continental climate marked by dryness and high temperature in the summer and a low temperature with the rarity of rain in winter as well as a high thermal range between the day and night and between summer and winter with a low relative humidity in the summer that raises in the winter. The seasonal rain is rare and the dominant wind bare is northwest in most of the year. This climate is characterized by being extreme due to the difference between high and low temperature which reaches 39 siliceous as well as the short transitional seasons (spring and fall)
