The purpose of this study was to document the species richness, distribution, and relative abundance of terrestrial amphibians and reptiles in ONP. There was high biological and management interest to inventory the current distribution of amphibian populations and to determine seasonal changes in detectability with repeated surveys at selected sites.
FIA/IF methodology
Sites were chosen from the U.S. Forest Service's FIA-point grid system that covers the Olympic Peninsula. Each FIA-point is a UTM coordinate (NAD 1927). Points are spaced approximately 1/2 kilometer apart in north/south and east/west directions. FIA-points were surveyed once within the two-year study.
At each FIA-point, one to four circular plots of 60-meter diameter were searched for reptiles and amphibians. Circular plot centers were spaced 200 meters apart in a square design around the FIA-point coordinate. The number of plots surveyed per FIA-point depended upon the time and steepness of the terrain. Each plot was searched for two worker-hours (i.e., two surveyors for one hour) during daylight hours. Surveyors visually searched the entire area of the plot by turning logs, rocks, duff, moss, and bark. Crews used a "light touch" approach, meaning anything that was moved was restored to a condition similar to its original state. The species, age class, and sex of each individual captured were recorded. A variety of habitat measurements were recorded per plot, including tree stem size classes, canopy cover density, downed wood, slope, aspect, and presence of water. Downed wood was measured by recording the decay class and length that a log intersected transects. There were four 10-meter transects per plot, each extended in the cardinal directions from the plot center. Environmental variables documented included air and soil temperature (C), relative humidity (%), wind and precipitation. We added a non-probabilistic survey to the study to: 1) target specific microhabitats that were unlikely to be sampled by the probabilistic surveys; and 2) supplement distribution and abundance records within ONP. Crews conducted these surveys at non-random sites chosen for unique habitat or when they had spare time. These "informal FIA" (IF) surveys had an identical sampling protocol to the FIA surveys.
Field data were entered into a PC database. All data entries were reviewed to ensure that the data were accurately entered. Before leaving each sampling site the assigned crew leader reviewed the data sheets. Data sheets were checked for 1) legibility; 2) completeness; and 3) accuracy. All records were written in easily readable print and confusing entries were re-written. Any conspicuously empty data fields were explained or filled. All data entries were checked for plausibility, and unusual entries checked with the other team members to confirm they were not errors.
Terrestrial habitats were eliminated if they fell on glaciers, large bodies of water, or had unsafe accessibility due to steepness (>37 degrees) of terrain and/or remoteness from trails or roads.
Data were checked for logical consistency by generating summary lists, and checking value ranges.
Are there legal restrictions on access or use of the data?
