Workshop

Audio and Video Technology for Wildlife Research Applications

Hosted and conducted by John and Ann Christensen, Sandpiper Technologies, Inc., Manteca, CA.

This workshop details how to apply the most recent developments in audio-video technology towards wildlife research projects. Attendees will learn how to analyze a research problem to create the most cost-effective and efficient means of gathering data. The audio portion of the workshop covers sensors, amplifiers and recorders, and the video information includes lenses, image capture devices, and processing/formatting electronics. Standard audio-video signal formats will be discussed, and new formats will be analyzed for their applicability towards wildlife research. A step-by-step approach towards making the decision to deploy audio-video technology includes cost/benefit analysis and designing research objectives to create a "shopping list" and specifications. The student will be able to complete a realistic budget using this information and determine if a pilot project is beneficial. Students of this workshop should be able to build a basic color camera. The attendee will have an understanding of the physical capabilities and limitations of the technology and have a better ability to specify the most cost-effective equipment.

This two-hour workshop was first presented at the National Conservation Training Center in August 2000 as part of their course "New Technologies for Fish and Wildlife Managers."

The 30-page handout for the "Audio and Video Technology for Wildlife Research Workshop" includes lecture/overhead notes and vendor information.

Workshop

Wildlife Habitat Mapping: an Assessment of the State of the Art

High quality habitat and vegetation data is critical to the management of California's wildlife resources. A number of resource agencies produce vegetation and habitat maps and classification systems to support their activities. These maps and wildlife models used with them predict habitats and species likely to be affected in any given area by a management decision. Four primary habitat and vegetation mapping efforts used in California are presented with regards to: (1) the method used to collect data in the field and classify remote imagery in the lab; (2) the major mapping product and its resolution and scale; and (3) the area of California covered. A panel discussion follows to compare the future of technology for each method, the best uses of each data set, and the best ways to coordinate collection and distribution of habitat and vegetation data between organizations. The workshop concludes with a presentation of a research project to test mapping products of different spatial scales with existing wildlife habitat relationships models.

Chair: Monica Parisi, California Department of Fish and Game, Sacramento, CA.

Workshop

Lyme Disease in California and the Wildlife Profession

California has the fourth-highest incidence of Lyme Disease among the 50 states based on statistics compiled by the Centers for Disease Control. However, many scientists believe Lyme Disease is vastly under reported by physicians and that many more cases exist. According to the Occupational Safety and Health Administration in a bulletin issued this past spring on the risk of Lyme Disease to outdoor workers, wildlife biologists and other outdoor professionals are at "particularly high risk" of exposure to infected ticks. As workers who spend a high percentage of time outdoors and who can be exposed to this extremely debilitating disease, it is important for wildlife professionals to be informed. This workshop will explore the ecology of the western black-legged tick and the relationship to wildlife field work, clinical manifestations and diagnosis of Lyme Disease, preventative measures while in the field, and provide a forum for wildlife biologists to discuss this disease with peers who have or have had Lyme Disease.

Sponsored by: CH2M Hill, Incorporated; EIP Associates, Incorporated; Environmental Science Associates, Incorporated; IGeneX; Jones and Stokes, Incorporated; KEA Environmental, Incorporated.
