British Columbia Marbled Murrelet Occupied Detection Surveys: Digital datasetEntry ID: UAF_murreletoccdet
Abstract: This data set contains the most complete known Marbled Murrelet occupancy
detections at inland stations at georeferenced locations throughout British
Columbia. Detection information includes total number of detections, total
number of audio, visual, audio and visual, and total occupied detections. When
more than one survey took place at a particular station, the survey ... information
is summed for a total detection. Summation can occur within years, or across
years. The number of surveys conducted, and the years the surveys took place
will be noted when available.
This database is a compilation of many sources and occupied detection is in
some cases defined by the original scientists. Otherwise protocol is set by
the Pacific Seabird Group (2000) as 1) Birds flying below canopy, through,
into, or out of forest canopy, 2) Birds perching, landing, or attempting to
land, or 3) Birds calling from a stationary position. A call is stationary
when more than 3 calls are heard.

Quality Various researchers have conducted the occupied detection surveys that are
presented, and while a protocol has been already established, there are
differences in the length of time and number of surveys per station depending
on the study. In some cases, the average occupied detection is reported and
... does not include the variance around that measure. Also, if user definition of
occupied detection differs from that of the PSG protocol, the original
documents must be consulted.
For some lake surveys conducted in Queen Charlotte Island no numeric values are
given, instead, the data reports only two classes of detection; extensive, or

Access Constraints The Centre for Wildlife Ecology is the owner of this compiled digital dataset
for research and publication purposes. This data cannot be distributed or
utilized without confirmation and agreement with the contributing parties.
Some data has been previously published elsewhere and is available for use.
This dataset is subject to updates.
Use Constraints Centre for Wildlife Ecology, Simon Fraser University is the owner of the

This dataset represent known Marbled Murrelet occupied detection surveys
conducted as of 1991. It presents the average occupancy status of stations
throughout inland British Columbia. The purpose of this dataset is to
contribute to the building of a Marbled Murrelet abundance and distribution
model. The intention is to compile a large-scale representation of Marbled
Murrelet inland activity in British Columbia.
