Relationships between small mammal survival and coarse woody debris in managed forests: a matter of spatial scale - Small Mammal Habitat Data

Geospatial_Data_Presentation_Form: spreadsheet

Description:

Abstract:

Woody shrub cover and above-ground coarse woody debris volume data collected on 10-m line intercepts centered on small mammal trap stations in two closed-canopy stands of Douglas-fir (Pseudotsuga menziesii) managed for wood products in the central Oregon Coast Range.

Purpose:

Data were collected as part of a CFER-funded pilot study to examine small mammal dispersal along riparian habitats and population responses to downed wood in the Oregon Coast Range.

Description_of_Geographic_Extent:

Central Oregon Coast Range in two Douglas-fir dominated forest stands that are managed for wood products in the vicinity of Alsea. One stand was located in U.S. Bureau of Land Management lands within the Little Lobster Creek watershed and the other in the privately owned Starker Forest in the Salmonberry Watershed.

Access_Constraints:

Data will become available when final report is approved by CFER.

Use_Constraints:

This was an observational study that lacked randomization, replication, and representation. Therefore these data should not be used for making broad inferences regarding small mammal survival. Inference is limited to the six specific 1-ha trapping grids sampled during this study. These data were collected to conform to Pollock’s robust design. In other words, these small mammals received trapping pressure that is unique to the repeated sampling associated with the requirements imposed by Pollock’s robust design. Therefore, the assumptions of other population models and analyses may be violated with these data.

Relationships between small mammal survival and coarse woody debris in managed forests: a matter of spatial scale - Small Mammal Trapping Data

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Performed double-blind data entry on 20% of data to evaluate accuracy. Performed Microsoft Excel PivotTable Reports for each variable based on unique ear tag numbers. Used the results from these PivotTables to verify sequence of captures, expected minimum and maximum values for each variable, presence of first capture for each unique ear tag #, and consistency for gender, reproductive status, and trapping grid.

Logical_Consistency_Report: Refer to Attribute Accuracy Report

Completeness_Report:

We recorded the diameter of each intercepted log that was > 10 cm in diameter and > 1 m in length, excluding snags and rooted stumps. We recorded the presence of vegetation along line intercepts at a minimum scale of 0.1-m (10cm).

Methodology_Description:

Above-ground coarse woody debris was sampled and volume (m3/0.01-ha) estimated at each 10X10-m micro site within each of six 1-ha square sampling grids using a 10-m line intercept centered over each micro site following methods similar to those outlined in Harmon and Sexton (1996). We recorded the diameter of each intercepted log (> 10 cm in diameter and > 1 m in length, excluding snags and rooted stumps), and used the formula described by Harmon and Sexton (1996) to estimate CWD volume.

Understory vegetation was sampled and cover estimated at each micro site by using the line intercepts (Bonham 1989) that were established for CWD sampling. Vegetation cover was classified as fern, herb/grass, or woody shrub (Pojar and Mackinnon 1994).
