Background

It is the

riparian habitats, including fish and wildlife resources that are dependent on
those habitats, and in such manner to protect and promote the public health,
safety and general welfare of the people (
A.R.S.
� 41-6001
).

Natural Resource
Conservation Districts (NRCD) are empowered to: 1) conduct surveys,
investigations and research relating to the character of the soil, soil erosion
prevention within a farm or ranch, methods of cultivation, farm and range
practices, seeding, eradication of noxious growths and invasive vegetation and
any other measures that aid farm and range operations; 2) create and administer
a soil health program;

3) conduct demonstration projects to demonstrate by example the means, methods
and measures by which water, soil and soil resources may be conserved and soil
erosion and soil washing may be prevented and controlled; 4) develop, publish
and bring to the attention of landowners, comprehensive plans for conserving
soil and water resources within the NRCD; 5) organize and establish an
education center to increase the knowledge of natural resources in Arizona; and

6) conduct other statutorily outlined powers (
