Bur Oak Leaves

Upcoming LAC Events!

How Old is that Oak Contest

March 15 - April 30

Just take a guess! One of the bur oaks in Guthrie Park, marked by a bow, has been scientifically measured to determine, as closely as possible, its age.  Was it here before the American Civil War?  Before the Great Chicago Fire of 1871?  Before the sinking of the Titanic?  Enter your best guess below and you might win $25 and bragging rights!

Fine print:  Only one guess per person, extra guesses will be discarded. Use any method you like to guess the age; however you may not perform any intrusive tests on the tree.  In the link below, enter the year you think the tree was planted.  In the case of a tie, winning entries will be drawn from a hat.  If you view the enhanced data on the Guthrie Park arboretum, please note that the tree’s estimated age is simply that – an estimate using very broad parameters.  Enter your contest guess here.


  • 7:00 p.m.
  • The 2nd Tuesday of the month (except November and December)

About the Commission

This group prepares and recommends to the Boards of Trustees a master landscape plan for all public areas, prepares an inventory of all trees and plantings within Riverside parks, and advises the Board of Trustees on treatment and disease prevention methods for all plantings. 

Riverside's public green spaces are integral to Frederick Law Olmsted's design, and to the Village's historic designation. To help preserve this treasured legacy, the Village's Landscape Advisory Commission is charged with developing a master landscape plan (PDF). The plan offers guidelines on how best to steward our public land in the present day.

Help Beautify Riverside 

The Landscape Advisory Commission works with volunteers throughout the Village to help beautify and maintain the landscape.  There are many volunteer opportunities including:
  • Special planting days
  • Stewardship of green spaces
  • Leading tours of the Village Arboretum or Natural Areas
  • Weeding and invasive plant control
This is an opportunity to meet some of your neighbors and improve our community. If you are interested in any of these opportunities or have ideas of your own, please contact the Village Office at 708-447-2700.
