The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
The District has a two-tier seed provenance system for purchase consideration of native plant material. First-Tier priority is given to species with origins (provenance) from locations within the attached range map. Any seed that does not originate from the defined First-Tier Zone may be considered for purchase at the District’s discretion as long as vendor provides the seed’s geographic location (County & State) and mile distance from Lake County, Illinois in the “Notes” column found in the contract’s Schedule of Prices.
