Background information and definitions
Barriers may be used to prevent pollutants from entering waterways. Examples of such pollutants include garbage, sediments, oil, grease, excess nutrients, organic waste matter, pesticides and fertilisers. A range of options for both temporary and permanent structures have been suggested, including silt fences and gabions (Botting & Bellette 1998). Barriers that excluded pollutants could have positive effects on wild reptile populations.
