Marmot Monitoring 2010 Results
Program Overview and Results of 2010 Field Season
Although unusually heavy snow cover limited access to many areas in July and early August, volunteers successfully surveyed more than 260 units and partially or visually surveyed another 42. Of the units that were thoroughly surveyed, 124 were classified as occupied (either saw marmots or fresh marmot sign) , 71 as abandoned (saw signs of past but not recent marmot use), and 65 as without sign of marmots. In addition, 7 were classified as abandoned and 35 as without sign of marmots following a visual or incomplete foot survey.
It is important to remember that the survey units were selected to include a high proportion of habitat patches that we thought contained marmots – so these numbers do not reflect the distribution of occupied marmot habitat park-wide.
The great value of this data, however, is that it is the foundation against which we will track changes in the percentage and distribution of units occupied by marmots over time.
Designations of "occupied", "abandoned", and "no marmot sign" from the 2010 survey are also consistent with results from a survey conducted in 2002-2006 by professional wildlife technicians, providing further evidence that citizen scientists can do a great job surveying for marmots!
Changes for 2011
The recruitment information more completely details necessary skills and experience.
The application process has been streamlined.
Surveys will be restricted to August to reduce problems associated with late snow-cover.
Survey units have been modified to better conform to marmot habitat. Units that were extremely difficult to access have been removed.
New software will allow survey units to be displayed as part of the background maps on GPS units.
GPS training will be improved and reference material made available before training.
Every volunteer will be given a GPS unit.
Did You Know?
Although related to other marmots and groundhogs of North America, the Olympic marmot is unique. An endemic species, it is found only in the Olympic Mountains. Visitors to the high country of Olympic National Park may be lucky enough to encounter a marmot sunning itself near its burrow.
