Dates: 07/01/2007 to 12/31/2009
Frequency: Several-days/week
Time of day: Morning, Afternoon, Evening
Areas to be used: western CSS, central CSS, eastern CSS
Facilities or equipment needed: None
Will any plant or animal species be studied? yes - Plestiodon (formerly Eumeces) skiltonianus — western skink
Will plants or animals be collected? no
Will vertebrate animals be collected or manipulated? no
Will markings or flags be used? yes - We will use either colored surveyors' tape or typical field flags to mark the locations of cover boards.

Description of research project: Habitat enhancement for western skinks.

We propose to provide cover boards to enhance the habitat for western skinks at BFS, and to facilitate future surveys of skink abundance. Western skinks are one of the least frequently seen reptile species living at BFS, in part because of their cryptic behavior. We propose to provide up to 30 cover boards in CSS habitat in the CSS habitat between pHake Lake and Foothill Blvd. Cover boards are either solid wood or plywood, from 0.25 to 1.0 inches thick, and typically 1-2 feet wide and 2-3 feet long. They are placed flush with the ground, and often have a 1-inch spacer board attached to the underside to ensure space between the ground and the board. Boards will be placed in habitats where I have observed skinks in the past, and will occasionally be turned over to search for skinks. Skinks are most active during the spring months (J.Q. Richmond, Cornell University, personal communication), so we will concentrate our search efforts in the spring.

Cover boards are commonly used to enhance habitat and facilitate field study of a variety of reptiles and amphibians, because they provide excellent refuges that are easy to inspect without being damaged. Skinks are frequently found beneath objects on the ground, and we expect skinks to readily make use of these cover boards.

In this phase of the project we do not plan to capture skinks. If future studies involve capturing skinks we will obtain collecting permits and animal care committee approval.

Cover boards are likely to be used by other vertebrate and invertebrate animal species, which we view as a benefit.

Description of research project: Continuation of previous research conducted by Dr John Gamon, relating plant optical properties (spectral reflectance) to physiological properties. Besides measuring spectral reflectance, other non-destructive tests will include plant gas exchange (measuring CO₂ absorbed vs water transpired). The overall purpose of the research is to determine the relationship (if any) between the optical reflectance and the amount of water transpired by the plant.

Existing plots will be resurrected with removal of dead plant species and repair (if needed) of existing irrigation system. Potential future planting of additional non-invasive, native California plant species in empty plots may occur. Permission will be obtained before introducing additional species.

Description of research project: This is the beginning of a long-term project designed to begin identifying the insect fauna present at the field station, and to investigate how taxa and numbers vary from site to site, over the year, and between years. Initially, four square sites in coastal sage scrub, 5m on a side, will be identified with flagging tape and located with GPS. Data will be collected the first weekend of each month using pitfall traps, sweep nets, and inspection of the foliage. The insects will be identified as far as possible and preserved to provide a reference collection. Pictures of the insects will be posted on the web. This project may be expanded if more students become interested in it.

Dates: 04/10/2006 to 09/30/2009
Frequency: Several-days/week - Frequency varies with need
Time of day: Varies - varies with project phase
Areas to be used: western CSS, central CSS, eastern CSS, lower neck
Facilities or equipment needed: Outdoor classroom, Line power, if available; otherwise we can set up solar panels
Will any plant or animal species be studied? yes - Entire ecosystem
Will plants or animals be collected? no
Will vertebrate animals be collected or manipulated? no
Will markings or flags be used? yes - The project entails installation of an eddy covariance tower (for surface-atmosphere CO2 and water vapor flux measurements) and a 100-m tram (track on raised rail) for remote sensing measurements with a robotic cart (like the Mars Rover, but on a track here on Earth).

Description of research project: The purpose of the project is to develop and validate optical and thermal sampling methods for estimating surface-atmosphere fluxes of biologically and radiatively active gases (CO₂ and water vapor, in this case) - the “breathing of the planet.” To do this, we would install an eddy covariance tower (large tripod with meteorological instruments to measure surface-atmosphere gas fluxes) and a tram system (robotic cart on a 100-m track) to measure ecosystem optical and thermal properties. The project is part of SpecNet (http://specnet.info/) and FLUXNET (http://www-eosdis.ornl.gov/FLUXNET/) networks, and is funded by National Science Foundation (Ecosystems and CREST) grants to John Gamon. Our initial goal would be to setup and test the instruments at this site for possible deployment elsewhere. Depending upon the quality of the site and measurements, we may choose to ask for indefinite access (a more-or-less permanent site).

Project description: Students will be comparing the habitat preferences of the two species of woodrats that are at BFS. I will be attaching small, removable radio collars to woodrats. The students will relocate the rats several times a week. They will map their locations and will measure vegetation characteristics where rats are found. Traps for woodrats will be placed in the evening and checked several times during the night to ensure that no rats are sitting there too long. After capture they will be weighed and sexed, fitted with the radio collar and given a PIT tag. This is a small injected tag that reads like a bar code. This method is preferable to ear tags because ear tags often get pulled out and rip the ears of the rat. All the protocols have been approved by the Fish and Game for both species. Students will be responsible for relocating the rats while they are out foraging. They will need access to BFS at dusk and at night (this is one reason why I want to use BFS; it is safer than sending them elsewhere). These are all advanced biology students who are familiar with BFS and its rules. Students will also make maps of all the woodrat houses that they can find. It is my hope that this project will continue throughout the summer and next fall. Woodrats will be recaptured to remove the radio collars when the batteries start to run out.
