Examples of Field Surveys

Soil and detrital carbon assessments in forests of northern California  
Ongoing project to assess soil and detrital carbon stocks in three forests as part of a larger study on effects of canopy closure on carbon storage.  Contract with the USDA PSW Forest Sciences Lab.  Fluxes among pools are also being measured to assess changes.  Click here to view poster presented at American Geophysical Union meetings 2015  Carbon Methods AGU Poster 2015 PDF. Carbon Budgets AGU Poster 2016, PDF

Forest carbon assessments in SE Alaska and Northern California
Quantified carbon in living above-ground trees and in detrital pools of woody debris, forest floor, and soils.  Parameterized data into user-friendly model to game different scenarios of carbon storage. Model Northern California Carbon Budget excel file.

Biological assessment of stream with varying levels of stream-side forest harvests
Conducted depletion-pass electrofishing surveys of small streams in the Coast Range of Oregon that had varying levels of forest harvest and incoming solar radiation.  Also collected periphyton data and macroinvertebrate counts. Results show increased biological response with increased radiation.  Click here to view slide presentation.

Effectiveness monitoring of restoration projects in the Shasta Basin
Designed a series of riparian and in-channel surveys based on draft protocols of the California Department of Fish and Game.  Statistical tests were performed to show the effects of cattle exclusion fencing on rates of recovery of riparian and in-channel processes.  Work involved collaboration with local landowners, the Shasta Resource Conservation District and the State.  Results showed beneficial responses begin to occur by year. Click here to view Introduction section of report.

Stream surveys
Twenty projects during 1995-2010; Region 6, Level II protocols have been performed for the following national forests: Willamette, Siuslaw, Umpqua, Malheur, Rogue River, and Gifford Pinchot, Olympic. Surveys using ODFW protocols have also been performed for watershed councils. Over 2,000 miles of streams have been surveyed ranging in size from headwaters to 4th order rivers. Surveys include physical and hydrologic measures of stream channels, mapping of basins, fish abundance and distribution, and riparian condition characterization. Over ninety stream survey reports have been prepared that include data summaries and GIS products.  Upper extent of fish use surveys. Multiple-year projects during 1996-2010 for a variety of clients. The upper extent of fish use has been mapped for over 2,000 miles of streams in the Coast Range and Cascade Range. Surveys employed electrofishing techniques and include species identification, stream habitat typing, and mapping.

Stream restoration
Selection of streams, design, permitting, and training of equipment operators were performed in projects where woody debris structures were placed streams.  Restoration was based on presence of coho rearing potential and on conditions of habitat. Effectiveness monitoring has shown success of structures in creating increased complexity, bedload aggradation, and improved coho habitat.

Mapping of streams
Located and mapped small (Class 4) headwater streams on BLM lands in the Eugene District and on Forest Service lands in the Willamette National Forest.  Marked and traversed harvest buffers along the streams using both laser rangefinders and traditional compass and survey tapes.  Surveyed small landslides along streams and performed restorations using mulch and native grasses.

Stream and riparian inventories
Performed physical measures on small headwater stream channels and forest plot measures using variable plots on approximately 20 streams on the east slopes of Mt. Hood of the Cascades Range, OR.  Approximately 400 channel transects and 800 forest plots were inventoried.  Data was entered into databases.

Flood effect surveys
Surveyed 11 streams in the Breitenbush Drainage to assess the flood effects on fish habitat. Surveys included Hankin and Reeves surveys and synoptic surveys.  Surveys showed the dynamic nature of these streams following the 1996 floods in Oregon. A 90-page report was prepared to document the changes using pre- and post-flood photo points.  A presentation was made at the 1997 Northwest Scientific Society Meetings.

Survey of riparian conifers
Performed an inventory of conifers in the riparian zone along twenty-one streams in the Siuslaw National Forest. Fifty variables were recorded and entered into spreadsheets. A 58-page synthesis document was prepared that highlighted the highly variable nature of natural conifer regeneration and relationships with species, woody debris nurse logs, overhead closure, and availability of seed sources.

Non-vascular plant surveys
Performed intuitive controlled surveys for Strategy 2 and Protection Buffer Species of fungi and bryophytes on 9,000 acres of forest lands in Grants Pass area. Created species lists for over 100 species of common fungi species and over 200 species of common bryophytes and lichens species.

Forest surveys
Relocated and surveyed 100 permanent forest plots in the Coast Range for the Confederated Tribes of the Siletz Indians.

Wildlife surveys
Performed surveys on 12,500 acres in the Fort Rock Ranger District, Deschutes National Forest.  Surveys were organized on 300-meter grids with broadcast calls. A summary report was prepared describing nesting density with comparisons to literature values.
