Conservancy “Research & Education Series”
The Conservancy posts research and education papers on its web site for public consumption. The purpose of these papers is to promote better understanding of the biological and scientific issues associated with the implementation of the Natomas Basin Habitat Conservation Plan (NBHCP) and the Metro Air Park Habitat Conservation Plan (MAPHCP). The Series seeks to serve as a resource for students, educators, the media and those interested in wildlife and the creation of habitat in the Natomas Basin of California. Series reports will be published on a periodic basis.
 Research & Education Series, #0904, Fish Sampling on Constructed Wetland 104 Kb
Fish Sampling on Constructed Wetland on the Natomas Basin Conservancy's BKS Tract. By Doug Leslie and Marin Greenwood.
- Executive Summary:
We took advantage of an opportunity to sample populations of non-native predatory fish in one of the marshes created and managed by the Natomas Basin Conservancy when the marsh was drained for routine maintenance purposes. Both largemouth bass and green sunfish were present in the marsh. Green sunfish appear to be too small to pose a significant risk of predation to giant garter snakes, although they may compete with giant garter snakes for prey. Largemouth bass pose a greater risk to giant garter snakes and management actions to control their populations may become necessary in the future.
Research & Education Series, #0903, Monitoring Avian Productivity, year-end 2008 108.63 Kb
Monitoring Avian Productivity and Survivorship (MAPS) in the North Basin Reserve in 2008. By Julia Camp and Doug Leslie.
- Executive Summary:
ICF Jones & Stokes biologists volunteered their time to establish and operate a MAPS station in 2008 on one of the tracts in the Conservancy’s North Basin Reserve. Mist nets were operated from May 25th to August 3rd, and resulted in the capture of 254 birds and 29 species.
Research & Education Series, #0902, Giant Garter Snake Status Report, year-end 2008 114.72 Kb
An overview of the status of the Giant Garter Snake in the Natomas Basin, California. February 2009. By Eric Hansen.
- Executive Summary:
This paper describes the 2008 season giant garter snake monitoring effort. The report draws on information provided in the 2008 Biological Effectiveness Monitoring Report. This report is used by the Conservancy to determine the general health and status of the giant garter snake in the Natomas Basin, and is conducted each year.
Research & Education Series, #0901, Swainson's Hawk Status Report, year-end 2008 108.00 Kb
An overview of the status of the Swainson’s Hawk in the Natomas Basin, California. February 2009. By Jim Estep.
- Executive Summary:
The Swainson’s hawk (Buteo swainsoni) is a state-listed threatened species in California and is a Covered Species under the Natomas Basin Habitat Conservation Plan and the Metro Airpark Habitat Conservation Plan. As part of the implementation of both HCPs, the Swainson’s hawk nesting population is monitored annually throughout the entire Natomas Basin in order to assess the status of the population and the effectiveness of the HCPs. To date, monitoring has indicated a fairly stable nesting population with the number of active nesting territories ranging from 43 to 59 between 2001 and 2008. Reproductive effort has also remained relatively stable during this period ranging from 1.38 to 1.67 young per successful nest. In 2008, 51 nesting territories were confirmed active with 42 of these successfully producing young for a reproductive effort of 1.52 young per successful nest.
