Get Involved

If you are concerned about protecting our Oregon skies from light pollution or just wanting to address lighting issues in your community, there are number of ways to get involved.

Join our IDA Oregon Chapter

IDA Oregon is an important part of the bigger picture that is the International Dark-Sky Association. Losing the quality of the night sky isn't just an Oregon issue... it's a global issue. Your membership is necessary to expand outreach and advocate for dark skies. To join IDA Oregon, please go to the IDA Member page. Make sure to specify you are with IDA Oregon.


IDA Oregon is 100% volunteer-driven. We value the dark-sky and are concerned enough to do something about it. Maybe you too would like to volunteer with us, in whatever shape or form, and help in our quest to protect Oregon's dark skies. Please contact us if you are interested or have any questions.


We are a subsidiary of IDA and make use of IDA-generated materials in our outreach. However, as a subsidiary we are responsible for our own financing. We don't have many expenses, but we still require funds for administrative expenses, copying, making banners, gathering data, etc. We are a non-profit with 501(c)3 status. Your donations are tax-deductible. Anything helps... and thank you in advance.
