(a) The Board of Supervisors finds that there exists a large number of elm trees in that area north and east of the San Bernardino Mountains generally known as the desert area in the unincorporated part of the County. That these are shade trees, and are an important constituent of the factors of property value in that area, and greatly contribute to the quiet enjoyment of land.
(b) The Board further finds that the elm tree population is threatened every spring and summer with destruction or serious damage and loss from the elm leaf beetle, an insect which comes into unusually high numbers of epidemic proportion during said seasons of the year.
(c) That unless concerted action is taken to combat the elm leaf beetle in the spring of each year, the entire area will be threatened with a loss of economic value and a lessening of comfort and enjoyment in the use of land.
