Abstract
This database contains information on species abundance according to date and location within the H.J. Andrews Experimental Forest Lookout Creek watershed. The database provides the information needed to assess patterns in the abundance of butterflies across time and space. The distribution and abundance of butterfly species on the Andrews Forest is strongly influenced by geographical scale, elevation, aspect, plant community, management regime, and time of year. Patterns of distribution and abundance are based on an historical total of 80 species, of which 73 are resident species and about 55 of which may be observed in any given year. Butterflies were surveyed at two- week intervals from late April through early October over a three-year period (1994-6). Approximately one-third of the watershed was covered during each visit, thus each area was sampled at about 6 week intervals within each sample season.

Abstract
- The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
- Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
- The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Study Area Description
-
Long-Term Ecological Research The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms.

The database provides the information needed to assess patterns in the abundance of butterflies across time and space. The distribution and abundance of butterfly species on the Andrews Forest is strongly influenced by geographical scale, elevation, aspect, plant community, management regime, and time of year. Patterns of distribution and abundance are based on an historical total of 80 species, of which 73 are resident species and about 55 of which may be observed in any given year. Butterflies were surveyed at two- week intervals from late April through early October over a three-year period (1994-6). Approximately one-third of the watershed was covered during each visit, thus each area was sampled at about 6 week intervals within each sample season.

Purpose: To detect patterns in the distribution and abundance of butterfly species in time and space across various plant communities within the entire HJA Forest watershed for multiple years.
Methods
Method Steps
Processing Procedure - SP016
- The survey data were entered into a notebook in the field. Field data were then entered into a database (Borland PARADOX, version 5.0) upon return to the lab. This database allowed for the retrieval of specific subsets of information that greatly facilitated analyses. HJA distribution maps were constructed for each species by placing small adhesive paper dots, representing site records, onto a topographic U. S. Forest Service map of the HJA Forest (1986, scale 1:24,000). In addition to showing elevation (contour interval 80 feet), roads and streams, the map information included watershed numbers, harvest units, and a grid of Township, Range and Section.
Field Methods - SA016
- Quantitative butterfly surveys were performed during mid-day hours (10:00am to 3:00pm) by driving slowly along roads and inspecting the sunny portions of roadsides and adjacent areas on foot. Individual butterfly checklists were made for each 1110th mile of road surveyed. Most records were based on sight identifications as most species were easily identified without capture. When the identity of an individual was in doubt, it was netted and identified in hand or was retained for positive determination upon return from the field.
Taxonomic Procedures - SA016
- Voucher specimens of virtually all species encountered were collected and deposited in the AFAC at Oregon State University. Each voucher specimen was provided with a data label denoting location, date of collection, and collector.
Sampling
Study Extent
- Sampling frequency: biweekly
Sampling Description
- Butterfly surveys were conducted throughout the Lookout Creek watershed of the HJA over 1- to 3-day periods during 1994 and 1995. Surveys occurred at approximately two week intervals and about one-third of the total watershed was sampled each time, on a rotating basis. The time between surveys, therefore, was effectively six weeks for any one portion of the HJA. Surveys commenced in April and May with the onset of warm, sunny weather and ended once cool, wet conditions prevailed in October. The highest elevations of the forest, including Carpenter Mountain and Frissell Ridge, were not visited until late May or early June due to the presence of snow drifts on roads which blocked access.
