Plan around observed ground conditions, not a calendar promise
Illinois forestry guidance supports limiting equipment in streamside areas to dry or frozen conditions, but that is not a guarantee of access or zero damage.
Scope noteWhere the streamside guidance applies, dry or frozen ground is the recommended equipment condition; it does not guarantee zero rutting or compaction.
- Surface dry, damp, saturated or frozen
- Recent ponding or rutting
- Slope and runoff direction
- Gate, field edge and crossing bearing condition
- Perennial/intermittent water and wet areas
- Forecast uncertainty and freeze-thaw risk
- Follow-up season for target regrowth
- Status
Needs site review
- Meaning
Default; observations are incomplete or mixed.
- Status
Potential lower-impact window
- Meaning
Conditions appear dry or frozen, subject to on-site judgment and rules.
- Status
Defer or change access
- Meaning
Saturation, active runoff, thaw or weak crossings create obvious disturbance risk.
Guaranteed workable, no-rut, no-compaction or zero-impact.
Weather and soil can change rapidly; the person performing the work must assess the site.
