Foothill Yellow-legged Frog (Rana boylii)

Regional Topics

In 2007, the FYLF Research Needs Conference was held at UC Davis. Participants involved included researchers and biologists from agencies, academia, and consulting. Research topics and needs were identified by participants split into regional groups, and region-specific risks were identified. Regions included: northern Coastal Range watersheds, central Coastal Range watersheds, and Sierra Nevada watersheds. Watersheds draining the interior northern coastal ranges (e.g. into the upper Sacramento River) were included in the northern Coast Range group. Similarly, watersheds draining the interior central/southern coastal ranges were included in the central Coast Range group.

Regional groups presented and summarized notes, included here: TABLE

In addition, a series of presentations were then given on current/recent research in each region, pulsed flows studies, and sample/survey design issues. These are available online. The remainder of the meeting was open discussion on a variety of topics including basic ecology and attempts to identify consensus research needs. Three major focus areas were identified: Ecology, Hydrologic Regimes and Effects, and Population Estimates & Sampling Design. These were discussed in more detail, and summarized notes can be found online.
