Minimal impact and Leave No Trace practices (SACE Stage 2 Outdoor Education)
“Apply and evaluate minimal impact and Leave No Trace practices when planning and undertaking outdoor journeys in Australian natural environments.”
Minimal impact means travelling and camping so that you leave the environment as you found it. The Leave No Trace principles cover planning ahead, travelling and camping on durable surfaces, disposing of waste properly, leaving what you find, minimising campfire impact, respecting wildlife and being considerate of others. On a journey you apply these in practice, choosing hardened tracks and sites, packing out rubbish, managing human waste and keeping groups small, then evaluate how well you protected the place you visited.

What this dot point is asking
You must apply and evaluate minimal impact practices when planning and undertaking journeys. This protects the environments you studied in Assessment Type 1 and demonstrates the responsible practice at the heart of the course.
Why minimal impact matters
Popular natural areas suffer cumulative damage from many visitors: trampled vegetation, widened and eroded tracks, polluted water, disturbed wildlife and litter. Australian environments are often slow to recover because of poor soils and fragile, specialised species. Minimal impact is the set of practices that lets people enjoy and learn from these places without degrading them, so they remain healthy for ecosystems, for First Nations custodians and for future visitors.
An internationally used framework of principles for low-impact outdoor recreation, designed so that the passage of a group through a natural environment leaves it essentially unchanged.
The core principles
Plan ahead and prepare, so you carry the right gear, keep groups small and avoid needing to improvise in ways that damage the environment. Travel and camp on durable surfaces such as established tracks, rock and hardened sites, rather than cutting new paths or camping on fragile vegetation. Dispose of waste properly: pack out all rubbish and manage human waste correctly. Leave what you find, taking nothing and disturbing nothing, including cultural sites. Minimise campfire impact, often by using a stove instead of a fire. Respect wildlife by observing from a distance and never feeding animals. Be considerate of other visitors and of the custodians of Country.
On hardened, popular routes you concentrate use by sticking to existing tracks and sites so damage stays contained. In pristine, lightly used areas you disperse use, spreading out and avoiding making any single path, so no trail forms. Choosing the right strategy for the setting is a key minimal impact judgement.
Waste and human waste
All rubbish, including food scraps and organic waste, is packed out, since scraps attract animals and disrupt their behaviour. Human waste is managed by using toilets where provided, or by burying it in a small hole well away from water, tracks and campsites, and by packing out toilet paper in sensitive or alpine areas. Washing is done away from waterways using minimal or no soap, so that detergents and food do not pollute streams that wildlife and other groups depend on.
Campsites, fires and tracks
Choose existing, durable campsites rather than clearing new ones, and keep groups small to limit impact. Stoves are preferred to fires because fires scar the ground, consume habitat, sterilise soil and pose bushfire risk; where fires are permitted, use established fireplaces and only dead fallen wood. On tracks, walk in single file along the centre even through mud, since walking around wet patches widens the trail and spreads erosion.
Applying and evaluating on a journey
For Assessment Type 2 you plan minimal impact measures before the trip and apply them in the field, then evaluate how well they worked. Strong evidence shows specific decisions: choosing a hardened campsite, packing out all waste, using a stove, keeping to the track, and any compromises you had to make. Evaluating honestly, including where impact occurred and how you would reduce it next time, shows the environmental responsibility examiners reward.
Linking to the wider course
Minimal impact connects your conservation study in Assessment Type 1 to action, protecting the biodiversity and environments you investigated, and it reflects the caring for Country approach of First Nations land management. It also deepens the connection to place you reflect on in Assessment Type 3, since caring for an environment is part of belonging to it.
Step 1: Plan ahead for the setting
Before the trip, decide whether the route is hardened and popular (concentrate use) or pristine and lightly used (disperse use). Pack a stove, rubbish bags and a trowel accordingly.
Step 2: Choose durable surfaces
In the field, camp on an existing hardened site and walk single file along the track centre, even through mud, so you do not widen the trail or trample fragile vegetation.
Step 3: Manage waste and water
Pack out all rubbish including food scraps, manage human waste correctly away from water, and wash away from streams with little or no soap so detergents do not pollute.
Step 4: Evaluate honestly
Afterwards, judge how well you protected the place, noting any impact (for example a compromise when no hardened site was available) and how you would reduce it next time. Specific decisions plus honest evaluation are the high-mark structure.
A common error is treating minimal impact as just packing out rubbish. It is a whole system covering surfaces, waste, water, wildlife, fire and other people. Another error is reciting the principles without applying them to your actual journey; marks come from showing the specific choices you made in a real environment and honestly evaluating their effectiveness.
Assessment-style questions
Questions on this dot point, each with a worked answer, written by ExamExplained. Outdoor Education has no written exam, so use them to check your understanding before your assessment tasks.
Practice4 marksExplain the principle of concentrating or dispersing use, and how a group should manage human waste on a journey.Show worked answer →
Four marks: concentrate or disperse (about 2 marks) and human waste (about 2 marks).
On hardened, popular routes, concentrate use by sticking to existing tracks and sites so damage stays contained (1 mark). In pristine, lightly used areas, disperse use, spreading out so no single path forms (1 mark).
Human waste: use toilets where provided, or bury it in a small hole well away from water, tracks and campsites, and pack out toilet paper in sensitive or alpine areas, so waterways are not polluted (2 marks).
Practice3 marksExplain why a stove is generally preferred to a campfire under minimal impact principles.Show worked answer →
For 3 marks, give reasons linked to environmental impact.
Fires scar the ground and sterilise the soil, and collecting wood consumes habitat that animals and decomposers depend on (1 mark). Fires also pose a bushfire risk, especially in dry Australian conditions (1 mark).
A stove avoids these impacts, cooks more reliably and leaves no trace, so it is preferred; where fires are permitted, established fireplaces and only dead fallen wood should be used (1 mark).
