TITLE: Survey of Vertebrate Populations Occurring in the H. J. Andrews Experimental Forest OBJECTIVES: 8.48 1. To estimate the relative species composition, abundance, and seasonal and yearly variations in presence and abundance of mammals, birds, amphibians, and reptiles on a representative sample of the habitat types and successional stages found in the area. (Studies will concentrate on the unit watersheds and reference stands.) 2. To assess the influence of each of these groups of vertebrates on the productivity of Douglas-fir and other conifers on the area. 3. To estimate productivity of vertebrates in terms of IBP-specified units (Petrusewicz and Macfayden, 1070). APPROACH: Part 1. Mammals. Small mammals will be censused following North American Census of Small ilammals sampling procedures (Calhoun, 1159). Long-term, continuous-removal trapping will be conducted in the spring simultaneously at study areas within each forest type, but sampling in the high-elevation, mixed conifer stands will follow censusing in the low-elevation forest type. The linear regression method of Hayne (1949) will be used to estimate rodent numbers. Reconnaissance surveys of the area will be made to estimate the distribution and abundance of other species of mammals. Information from the literature survey (IBP, Black) will be combined with field data to provide estimates of species present, distribution, relative population densities, and impact on productivity. Estimates of deer numbers and deer use of habitats will be based on direct observations and counts of deer-pellet groups. Pellet groups will be counted and removed periodically on permanent sampling plots randomly located on each area sampled. An estimate of deer browsing on Douglas-fir and other conifers will be based on periodic examinations of established and planted seedlings. Survey procedures will be adapted from methods followed by Crouch (1970) and Swanson (1970). Part 2. Birds. Avian populations will be censused in three stand types, employing variations of either the sample-count method (Bond, 1957) or a variable strip census developed by Emlen (in press). As the research program develops, other census methods may be applied to specific groups of interest, e.g., woodpeckers (Baldwin and Amman, 1160). Inventories will concentrate on obtaining a quantitative estimate of species presence and abundance in each of the six seasonal phases (Anderson, 1970), in each of three stand types. A minimum of three sequentially replicated samplings will be required to obtain some measure of variance for the population estimates. Thus, in all a minimum of 54 censuses during the year will be required.
8.49 Data from these studies, together with information from the literature on these parameters and on estimates of weights and feeding habits, can provide rough estimates of biomass and trophic structure of the stand avifaunas. Part 3. Amphibians and Reptiles. Intensive collecting (day and night), particularly on favorable habitats on the unit watersheds and reference stands, will be carried out by the principal investigators and graduate assistant, with other help from cooperating biologists and classes. These collections will be made periodically from March through November, weather permitting. Amphibians and reptiles encountered will be identified, individually marked, weighed, measured, and released. Subsequent captures will give information on growth rates and permit estimates of population size. Specimens also will be collected for stomach analyses to supplement published information available on feeding habits. PERSONNEL: Principal Investigators: Hugh C.
