c. Mitigation for foraging areas shall be a mini== 1:1 acre ratio (i.e., 1 acre replacement for each 1 acre loss of habitat) and with a minimum of 10% acquired in fee and actually managed for Swainson's hawk habitat. Increased mitigation ratios may be necessary in certain instances in order to maintain adequate foraging habitat to support Swainson's hawk populations or if a project site provides breeding or foraging habitat for more than one pair. Due to its seasonal availability and tial high value during limited periods, mitigation for rice lands shall be at a minim= of 0.5:1 ratio. Lands shall be considered as rice habitat only if farmed to rice for seven of the ten previous years and 15 of the previous 20 years. Habitat management plans for several areas are currently being prepared which may identify new information regarding habitat requirements for nesting pairs. Therefore, these criteria are to be considered interim guidelines and mitigation ratios may increase for future projects based on additional information from scientific research on this species. D. Retention of Habitat Retain and create sufficient quality habitat to maintain existing population levels and to allow for future population increases to meet recovery goals for the Swainson's hawk (as to be determined by the Swainson's Hawk Recovery Plan) . 1. Restoration and enhancement of Swainson's hawk nesting and foraging habitats through the creation and establishment of habitat management areas. a. Mitigation areas must meet the following minimum criteria: i. Minimum acreage size of 1,280 contiguous or semi- contiguous acres of suitable habitat. Smaller individual projects may participate in mitigation banks or fee assessment programs to acquire the minimum acreage needed to support a nesting pair. 10
