Litter - Sourced from Daubenmire

Description

This data set contains litter depth in cm sourced from daubenmire survey observed at 10m intervals inside a 0.5m square along a transect.

Usage

litter

Format

A data frame with the following variables:

• date: Date, the date survey was taken

• round: character, the round number: 1, 2, or 3

• transectID: character, id of the transect

• section: character, point along the transect at which data was collected inside a 0.5m square

• depth: numeric, depth of horizontal dead plant material on the soil surface in cm. cm values limited to measurement by 0.25cm increments.

Data Collection Protocol

**Note** Daubenmire and robel data share the same directory and are both saved with the same file name except that robel data is saved with a '2' after the .csv extension. site_transect_round.csv2

Daubenmire survey was done at 10m lengths along a permanent transect line

Observer placed a quadrant (1 meter x 0.5m rectangle) on the left side of the transect

Quadrant was placed with 1 meter edge perpendicular to the 100m tape and 0.5 meter edge extending from transect point to 0.5 meters along transect length.

Observations started at 0 meters on the transect and were taken every 10m of the transect.

Observations were at a point on the transect and did not encompass the full length of a section.

Data collection began at 0 meter starting point of the transect and stopped before the transect ended.

A transect length of 100m will have points recorded for 0 meters through 90 meters; 10 points.

Data is not taken at the final point on the transect as this area is outside the transect.

Some litter values were only given as <.25, <.5, or >.5. The inequalities have been removed, but are available in daubenmire_raw.
