Olympic National Park Terrestrial Herp Survey 2000-01

Frequently-anticipated questions:


What does this data set describe?

    Title: Olympic National Park Terrestrial Herp Survey 2000-01
    Abstract:
    This database represents the results of a two-year survey (2000-2001) of amphibians and reptiles in Olympic National Park. The database contains records of probabilistic surveys, which were terrestrial surveys for reptiles and amphibians conducted at sites corresponding to FIA points throughout ONP. Additionally, non-random sites were chosen for suitable herpetofaunal habitat and were surveyed under a protocol identical to the FIA surveys. A related database (Olympic National Park Terrestrial Herp Incidental Records 2000-01) contains records of incidental surveys, which were opportunistic, non-random surveys conducted throughout ONP in habitats deemed suitable for reptiles and amphibians.

Why was the data set created?

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.


How was the data set created?

  1. What methods were used to collect the data?

    Method 0 of 1
    Type: Field

    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.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    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.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    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.

  5. How consistent are the relationships among the observations, including topology?

    Data were checked for logical consistency by generating summary lists, and checking value ranges.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
