AECOM conducted baseline biological surveys of the County of San Diego?s Sage Hill Preserve (Preserve). This effort was undertaken to provide biological data, information, and analysis to the San Diego County Department of Parks and Recreation (DPR) to aid their development of a Resource Management Plan with Area Specific Management Directives for the Preserve. To evaluate the Preserve?s biological resources, AECOM performed the following studies: a) vegetation mapping; b) sensitive plant surveys; c) invasive plant surveys; d) butterfly surveys; e) amphibian surveys; f) reptile pit traps and surveys; g) avian point counts; h) nocturnal bird surveys; i) acoustic surveys and roost surveys for bats; j) small mammal trapping, and k) camera survey stations for medium and large mammals. This report describes all survey methodologies, data collected, and analyses performed during the survey, which occurred from February through December, 2009. The report also includes management recommendations based on the survey results. These recommendations cover management and monitoring of sensitive plant and animal species, including species covered by the North County Multiple Species Conservation Program (North County MSCP). It also includes recommendations for management and monitoring of vegetation communities, control of invasive non-native plant species, and other recommendations to ameliorate illegal collection of animal species from the Preserve. The Preserve covers approximately 231.51 acres of native and non-native habitats, including Diegan coastal sage scrub, southern maritime chaparral, coastal sage-chaparral scrub, coastal and valley freshwater marsh, southern oak riparian forest, non-native grassland, disturbed habitat, and tamarisk scrub. All of the Preserve is within the proposed North County MSCP preserve system. The 2009 surveys documented 8 vegetation types and 239 species within the Preserve. The species detected included 146 plant species (of which 97 were native), wildlife surveys detected 13 butterfly species, 4 amphibian species (including one non-native), 8 reptile species, 48 bird species (including one non-native), and 20 mammal species (including one non-native). Of these species, there are 11 special-status species of which six are North County MSCP-covered species (2 plants and 4 animals).

The twenty-ninth annual census of the Light-footed Clapper Rail in California was conducted from 9 March to 5 June 2007. Thirty coastal wetlands were surveyed by assessing call counts from Carpinteria Marsh in Santa Barbara County, south to Tijuana Marsh National Wildlife Refuge (NWR) on the Mexican border. A total of 443 pairs of Light-footed Clapper Rails exhibited breeding behavior in 19 marshes in 2007. This is the largest statewide breeding population detected since the counts began in 1980, representing an 8.3% increase over the former high count in 2006 and a 36% increase over the 24-year high reached in 1996. This is the fourth year in succession of recordbreaking high counts. Upper Newport Bay was once again the largest subpopulation in California and was back to its second highest total. Tijuana Marsh NWR was at an all-time high level of 142 pairs, a 39.2% increase over 2006. The Newport subpopulation comprised 37.3% of the state population in 2007 and the subpopulation in the Tijuana Marsh NWR comprised 32.1%, together accounting for nearly 70% of the breeding population of this rail in California. The subpopulation on the San Dieguito River dropped 50% to 15 pairs but remains the largest ever recorded in a freshwater marsh. There were 15 pairs at Point Mugu, its third highest total and the Seal Beach tally was up slightly to 24 pairs. Batiquitos Lagoon held a record high 1 Zembal, R., S. Hoffman, J. Konecny, C.

Three other small subpopulations were at record or recent highs including Buena Vista Lagoon with 8 pairs, San Elijo Lagoon with 12 pairs, and San Diego River with 6 pairs. The San Diego River total included two pairs discovered at Kumeyaay Lake about 8 miles inland of Mission Bay. Additional nesting activity was observed in 9 of 15 breeding territories at Point Mugu. Incubation nests were found in 5 territories, brood nests in 3 territories, chicks were observed in 2 territories, and there was evidence of chick feeding in 9 territories. No egg translocations were accomplished because of the asynchrony in incubation timing between Newport and the target marshes. No eggs were taken from Newport to augment the capti
