Model selection and validation are now complete for the Westside elk habitat
models; a comprehensive summary of this phase of the project is available.
Biologists and planners with the Forest Service, Bureau of Land Management, Washington Department
of Fish and Wildlife, and several tribal nations have applied the Westside
models and reported their results back to the modeling team. The team is now
completing a comprehensive monograph that will provide the scientific foundation
for long-term, credible management use of these new tools.
in vegetation and potential differences in elk nutritional resources exist
between southwest Oregon and the Westside modeling region.
To address these differences, scientists collected additional data in 2011
using tame elk in grazing trials throughout this corner of the state. Nutritional analyses are now complete, and the team is developing a new nutrition model for southwest Oregon that can be incorporated into the Westside
use model and subsequently applied in this region.
Federal land management agencies in Oregon and Washington formally adopted the elk nutrition and habitat use models in management in early 2013. The modeling team will continue to offer training sessions and other technology transfer activities to help managers with efficient and timely application of the models. Please contact Jennifer Hafer (firstname.lastname@example.org) for technical assistance with the Westside models.
The elk modeling team hosted the second and final Westside elk habitat modeling
workshop over two
days – Tuesday, April 5 and Wednesday, April 6 – at
the Embassy Suites Hotel in downtown Portland.
Tuesday, over 100 attendees listened to a full day’s slate of presentations
(see links above) describing the project background, modeling methods, the
final models and results of their validation, model application in example
landscapes, and a project summary. The afternoon’s presentations included
talks by project beta testers, who had worked with the modeling team to test-drive the models in their home offices and then applied the models to on-the-ground
projects in their own areas. On Wednesday, a smaller group of modeling enthusiasts
returned for a hands-on demonstration of the suite of “toolboxes” used
to apply the elk nutrition and habitat use models on the landscape.
of the presentations from this workshop are available on DVD; please contact

The first of two planned workshops, “Elk Habitat Selection in Western
Oregon and Washington: Models for
a New Century,” was held on April 19-20,
2010, at the LaSells Stewart Center at Oregon State University in
120 biologists and land managers from a variety of state, federal, tribal,
academic, and private organizations gathered for two days to learn about new
approaches to modeling elk habitat selection in western Oregon and Washington.
Members of the interagency team conducting this project described the background
of the work and shared draft modeling results and example management applications
through a series of presentations (see links above). During the second day, participating breakout groups offered feedback to the team about the model components and their applicability in Westside elk management. A summary of the workshop findings is available.
Modeling team member Jennifer Hafer explains details during the hands-on model demonstration
at the 2011 workshop in Portland.
