Rain Garden Work Group


Rain Gardeners take special care of our rain garden nestled within the Arctic Passage. With regular greetings from seals and our sandhill crane (Buckbeak), gardeners enjoy the great outdoors while bringing beauty to grounds. Even more importantly, they support our second largest browse garden by caring for several edible trees and hibiscus that go to feeding our animals. Finally, the rain garden also triples as a functioning song bird garden – supporting song birds in the wild with a safe habitat and edible plants.

This is a wonderful role for those with attention to detail who are looking for something a bit more removed from the direct interaction with guests that comes with other ongoing volunteer roles. Work under the guidance and supervision of our Horticulturalist, and join a small team of volunteers as you dig in the dirt – helping with weeding, mulching, raking and light landscaping.

Volunteering For All

Rain Gardeners volunteer outside in mostly open sun (though, shade can present itself in the early mornings when the shadows are longer). The rain garden is located at the end of Arctic Passage next to the seal enclosure and Animal Health Center (AHC). The closest public restroom is in the center of the Zoo at the Glacier Grille. The terrain in the rain garden is very uneven with many dips and muddy spots. It is the quietest spot in the entire zoo – with the occasional exception of seal and crane calls.

The rain garden requires attention to detail that would work well with someone who enjoys sitting in one place and hyper-fixating on one task at a time. We have many tiny weeds that will only be defeated by tenaciously pulling them up by the roots. Because most of the work will be weeding, this is excellent for someone who thrives on consistency.

Requirements & Skills
  • At least 18 years of age
    • Possible consideration for 16+ with a parent/guardian
  • Strong gardening background
  • Strong attention to detail
  • Able to easily switch between sitting and standing

Time Commitment

9hrs/mo: Rain Gardeners commit to a weekly shift with a minimum of x3 shifts/mo between Late April and the end of September.

Weeding is the name of the game for Rain Gardeners. Weeds grow substantially faster in this type of environment. While there will be other projects, expect consistency throughout the season.

Weather Policy

Henry Vilas Zoo is open regardless of weather. While we remain open, we trust our Rain Gardeners to decide whether or not they would like to volunteer in light precipitation, cold/hot temperatures, etc. The volunteer is in charge of scheduling a make-up shift in the event they choose to stay home due to weather.

In the event of truly inclement weather, we will call volunteers to cancel. In this case, volunteers do not need to make up their cancelled shift.

Rain Garden Volunteer Application

Applications for 2024 the Rain Garden Work Group will be going up Thursday, February 1st, 2024 at 12PM. This role has limited availability due to most of our volunteers returning for another season (yay!).
