Michele Sadauskas, Oneida County Conservationist and dark sky enthusiast, takes an important topic like connecting with our night skies and makes
it FUN and informative! 

View her presentation below
for helpful information on how you
can help yourself, our wildlife,
and our insect friends benefit the
most as we protect and preserve
our dark skies.

Connecting with our Night Sky:
How to Preserve &
​Protect Dark Skies in the Northwoods


Dark Skies Presentation

​​Star Party Highlights

     Nearly sixty people ranging from kids to grandparents joined together under perfectly beautiful clear skies on Thursday, August 21, 2025 for the first ever Star Party at Nicolet College Fieldside Center!

The Star Party, sponsored by the Oneida County Land and Water Conservation Department, Northwoods Explorers of Space and Astronomy, and Nicolet College
offered tips on star gazing, dark sky preservation,
​and other valuable information to help keep light pollution to a minimum.

Winners were drawn for the Themed Painting by Tom Barnett and an Aurora Pillow donated by Michele Sadauskas, County Conservationist. 
WINNERS:
Star or Aurora Pillow - Jillian Self
​Star-Themed Painting - Emma Edinger

​Did you know. . .

that 80% of Americans cannot see the Milky Way; 35% of outdoor light is wasted, costing about 3 billion dollars to, literally, be lost to space; and fireflies, hummingbirds, monarch butterflies, and owls are some ​of the animals most affected by light pollution?

       Artificial light can interrupt natural body rhythms in both humans and animals.  An increased amount of light at night can lower melatonin production resulting in sleep deprivation, fatigue, headaches, stress, anxiety, and other problems.  ​
     Studies also show that light pollution can influence animal behaviors like migration patterns, wake-sleep habits, and habitat formation.  Because of light pollution, sea turtles and birds guided by moonlight can become confused, lose their way, and die. ​

​You Can ​Preserve the Northwoods Night Sky

What do you see
​when you look up at the night sky?

       Light pollution is just one of the many reasons our insects are on the decline.  You can read more about it at this link:

Bat Presentation

      A bat worksop was held at Town Line Park in conjunction with the Second Annual Northwoods Lights Out Event.

Bats and Lighting

      Light pollution has been a pretty hot topic for bat research in Europe for some time. Some of the effects appear to be from intensity of light rather than color. Read about light intensity  by clicking on the "Intensity of Light" button below.

      A study used a before-and-after design where they set up acoustic detectors on the lamp posts for a week prior to replacement and then a week after replacement of the bulbs. Check it out and click on the "Study" button below.

     In addition, below is a "Paper" on the effects of light color on bat activity. It mentions how they also measured insect activity, which is a great idea.  There are some species like big brown and eastern red bats that will regularly feed on insects (particularly Lepidopteran) near certain streetlights while there are other species like little brown bats who steer clear of these lit-up environments.

​      In addition to the presentation, Mary Beth presented at the North Central Land and Water Conservation Association Spring Meeting.  The entire meeting is on YouTube at the following location. (https://youtu.be/NncUwvxDVnE)  If you just want to watch and listen to Mary Beth's presentation, start the video at the 2:40:00 mark with an introduction from Michele Sadauskas, Oneida County Conservationist and Baerbel Ehrig, Oneida County Lakeshore Restoration Specialist & Pollinator Coordinator.

​Be Aware of Your Outdoor Lighting

     Insect populations, a primary source of food for birds and other animals are drawn to artificial lights and instantly killed upon contact.

     Safety-related dangers that come with poor visibility at night are caused by glaring lights or bad lighting design, which allows artificial light to shine outward and upward into the sky, where it is wasted instead of focusing light downward, where it does the most good. There are simple measures we can take to make our use of nighttime lighting most effective.
  • Install useful light only
  • Aim the light down
  • Remember that brighter isn’t always better
  • Choose LEDs wisely – color does matter
  • Use motion sensing lights or timers to help reduce illumination levels and save energy
  • Reduce unnecessary indoor lighting at night, particularly empty office buildings
  • Outdoor light fixtures that shield the light source can minimize glare and help prevent light pollution
