Meaning
A loose impediment is an unattached natural object, such as a stone, leaf, loose grass, branch, stick, dead animal, animal waste, or easily removable worm, insect, mound or web. Attached or growing objects, solidly embedded objects, sand, loose soil, dew, frost and water are excluded, subject to specific Rules definitions.
How it matters in match play
Match play uses the same Rule 15.1 treatment: a player may remove a loose impediment anywhere on or off the course, including a bunker or Penalty Area. If removal causes the ball to move, the ball is replaced and the player normally gets one penalty stroke under Rule 9.4b. That penalty stroke counts in the hole score; it does not automatically concede or lose the hole.

Worked example
Alex removes a loose leaf beside the ball and accidentally moves it, so Alex replaces the ball and adds one penalty stroke: four strokes played plus one penalty stroke equals five, matching Ben's five, so the hole is halved.

Common questions
Can I remove a loose impediment in a bunker?
Yes. Rule 15.1a allows removal without penalty anywhere on or off the course, including a bunker. Take care not to move the ball: outside the Putting Green or Teeing Area, causing the ball to move normally brings one penalty stroke and requires replacement.
Are sand and loose soil loose impediments?
No. The Definition of Loose Impediment specifically excludes sand and loose soil. A mound made by a worm, insect or similar animal is treated differently and is a loose impediment.
What happens if removing a loose impediment moves my ball in match play?
Replace the ball on its original spot and normally add one penalty stroke under Rule 9.4b, subject to the stated exceptions. The penalty is included when comparing the players' strokes for that hole; the opponent wins only if the resulting scores make the hole theirs.
Can a loose impediment be removed from the Putting Green?
Yes. Rule 15.1a permits removal on or off the course. If the ball is on the Putting Green and moves because of the removal, Rule 15.1b says to replace it, but the one-stroke penalty in that paragraph does not apply to a ball at rest on the Putting Green.
Is a movable bottle the same as a loose impediment?
No. A bottle is artificial, so it is usually a Movable Obstruction rather than a loose impediment. Both may generally be moved, but their definitions and some ball-movement procedures differ under Rule 15.
Can I remove a live insect from my ball?
Yes. The Definition of Loose Impediment expressly treats a live insect on a ball as a loose impediment. Remove it under Rule 15.1, while taking care not to cause the ball to move where the movement penalty applies.
