Question 1Outdoor and Environmental Studies

Which term describes the minimum impact approach to travelling and camping in natural areas, summarised by the phrase 'take only photographs, leave only footprints'?

  1. Wilderness zoning
  2. Ecological footprint
  3. Sustainable yield
  4. Leave No Trace Correct answer.

Explanation

Leave No Trace is a set of minimum-impact practices that guide how people travel, camp and dispose of waste in natural settings. Its core idea is that visitors should minimise visible and ecological change so the area remains as they found it.

Question 2Outdoor and Environmental Studies

In Victoria, which agency is primarily responsible for managing national parks and conservation reserves?

  1. Local councils
  2. Catchment Management Authorities
  3. The Environment Protection Authority
  4. Parks Victoria Correct answer.

Explanation

Parks Victoria is the statutory body that manages the state's national parks, marine parks and other conservation reserves on behalf of the public. It handles visitor facilities, permits and conservation programs within those parks.

Question 3Outdoor and Environmental Studies

An outdoor group wants to reduce the risk of a bushfire escaping from their camp. Which action best reflects safe campfire practice in a Victorian park?

  1. Leave coals smouldering so the next camper can reuse the site
  2. Use an established fireplace and fully extinguish the fire with water before leaving Correct answer.
  3. Build the fire against a large tree to shelter it from wind
  4. Burn only green branches because they produce less flame

Explanation

Campfires should be lit only in designated or safe hearths and must be completely extinguished with water and stirred until cold before departure. This removes the residual heat that can reignite and start a wildfire.

Question 4Outdoor and Environmental Studies

What does the term 'biodiversity' refer to?

  1. The total number of introduced species in an area
  2. The rate at which a habitat is cleared
  3. The variety of living things across genes, species and ecosystems Correct answer.
  4. The amount of biomass produced each season

Explanation

Biodiversity describes variation at three linked levels: genetic diversity within species, the number of species, and the range of ecosystems and their processes. All three levels contribute to the resilience of natural systems.

Question 5Outdoor and Environmental Studies

Which of the following best describes a 'wilderness' area under Victorian legislation?

  1. A park zone developed with roads and campgrounds
  2. Farmland set aside for future urban expansion
  3. Any public land that visitors may enter without a permit
  4. Land in a essentially natural state where natural processes operate freely Correct answer.

Explanation

Wilderness areas are defined as land that is largely unchanged by humans, where ecological and evolutionary processes continue with minimal interference. Access is typically restricted to foot travel to protect these values.

Question 6Outdoor and Environmental Studies

A hiker plans a multi-day walk and wants to reduce the chance of becoming lost or injured. Which strategy is most effective?

  1. Carry a map and compass, check the weather forecast and tell someone the itinerary Correct answer.
  2. Start late in the day so the route is cooler
  3. Walk alone to move faster and avoid group delays
  4. Rely on a mobile phone with a full battery as the only navigation aid

Explanation

Sound trip planning combines navigation tools, weather awareness and a shared itinerary so that help can be summoned if something goes wrong. These measures reduce exposure to hazards before the trip begins.

Question 7Outdoor and Environmental Studies

Which human activity is the leading cause of habitat loss in Australia?

  1. Wildlife photography
  2. Land clearing for agriculture and urban development Correct answer.
  3. Birdwatching surveys
  4. Recreational bushwalking

Explanation

Clearing native vegetation for farming, housing and infrastructure removes habitat and fragments what remains, making it the dominant driver of habitat loss nationally. Low-impact recreation does not remove habitat at a landscape scale.

Question 8Outdoor and Environmental Studies

What is the main purpose of a catchment management plan?

  1. To decide which species may be hunted commercially
  2. To coordinate land and water use so the quality and yield of water in a catchment are protected Correct answer.
  3. To set the ticket price for national park entry
  4. To map walking tracks within a single park

Explanation

Catchment management planning integrates land use, water quality and community needs across the whole drainage area that supplies a river or reservoir. Because water flows across boundaries, planning must happen at catchment scale.

Question 9Outdoor and Environmental Studies

A group camping on a popular alpine ridge finds a well-used existing campsite. Why is it often better to camp on the existing site rather than create a new one nearby?

  1. New sites always have better drainage than old ones
  2. Existing sites are legally the only places camping is allowed
  3. Concentrating impact on an already disturbed site protects the surrounding undisturbed vegetation Correct answer.
  4. Alpine vegetation recovers faster than lowland vegetation

Explanation

In fragile environments, concentrating use on an already compacted site limits the total area of damage. Spreading campsites creates many small scars that heal very slowly in alpine conditions.

Question 10Outdoor and Environmental Studies

Which statement best explains why introduced predators such as foxes and cats threaten Australian native mammals?

  1. Native mammals compete with predators for nesting boxes
  2. Native mammals evolved without these predators and lack effective avoidance or defence behaviours Correct answer.
  3. Introduced predators increase the food supply for native mammals
  4. Introduced predators only eat plants that native mammals need

Explanation

Many Australian mammals evolved in isolation from placental predators, so they did not develop appropriate anti-predator responses. Introduced predators therefore kill them at high rates, especially small and ground-dwelling species.

Question 11Outdoor and Environmental Studies

A school group wants to assess the condition of a local creek. Which combination of indicators would give the most reliable picture?

  1. The colour of the water after rain
  2. The number of visitors who walk beside the creek
  3. Water temperature alone on a single day
  4. Water clarity, dissolved oxygen, macroinvertebrate diversity and bank vegetation Correct answer.

Explanation

Creek health is best judged using several complementary indicators covering water chemistry, biological communities and physical habitat. Macroinvertebrates are especially useful because they integrate conditions over time.

Question 12Outdoor and Environmental Studies

Which of the following is an example of an indirect (non-extractive) use value of a national park?

  1. Grazing leases issued for cattle within the park
  2. Water piped from a reservoir in the park to a city
  3. Timber harvested from a plantation inside the park boundary
  4. Revenue earned by a town from visitors who come to walk in the park Correct answer.

Explanation

Indirect use values arise when people benefit from a protected area without removing resources, such as tourism spending linked to recreation and scenery. Extractable goods like timber, water and grazing are direct consumptive uses.

Question 13Outdoor and Environmental Studies

A bushwalker notices a leech attached to their ankle after walking through damp forest. What is the most appropriate first response?

  1. Cover the leech with sunscreen and leave it attached
  2. Ignore it entirely because leeches are harmless
  3. Pull the leech off quickly with dry fingers and continue walking
  4. Remove the leech carefully and clean the bite, seeking medical advice if symptoms develop Correct answer.

Explanation

Leeches should be removed gently, for example with a fingernail or salt, and the wound cleaned to reduce infection risk. Medical advice is warranted if the bite becomes infected or the person feels unwell.

Question 14Outdoor and Environmental Studies

Which factor most directly explains why many Australian plant species depend on fire for regeneration?

  1. Fire adds large amounts of nitrogen to the soil
  2. Burning increases rainfall in the following season
  3. Fire removes all competing introduced plants permanently
  4. Some seeds require heat or smoke to break dormancy and germinate Correct answer.

Explanation

Many Australian plants have evolved seed coats or dormancy mechanisms that respond to heat or smoke, so germination is triggered after fire. Fire also clears space and returns nutrients to the soil, supporting seedling establishment.

Question 15Outdoor and Environmental Studies

A park manager wants to reduce visitor impacts on a fragile alpine track. Which approach is most consistent with visitor management principles?

  1. Encourage visitors to spread out and walk on the vegetation beside the track
  2. Close the park to all visitors permanently
  3. Remove all signage so visitors rely on their own judgement
  4. Harden the track surface and install boardwalks in wet sections to concentrate traffic Correct answer.

Explanation

Hardening a track with durable surfaces and boardwalks concentrates use on resistant ground, protecting fragile soils and plants. This is a standard visitor-management technique that maintains access while limiting damage.

Question 16Outdoor and Environmental Studies

Which of the following best describes the concept of 'carrying capacity' in an outdoor recreation setting?

  1. The number of rangers needed to patrol a park each season
  2. The maximum number of vehicles that fit in a car park
  3. The total weight a hiker can comfortably carry
  4. The level of use an area can sustain without unacceptable ecological or experiential change Correct answer.

Explanation

Carrying capacity refers to the amount and type of use a site can absorb before unacceptable change occurs, whether ecological damage or loss of visitor experience. It links use levels to defined standards of condition.

Question 17Outdoor and Environmental Studies

A student argues that 'wilderness' is a social construct rather than a purely ecological category. Which evidence best supports this view?

  1. Wilderness areas contain only native species
  2. Wilderness areas are protected by legislation
  3. Areas now called wilderness were often shaped by Indigenous burning and were occupied before being declared empty Correct answer.
  4. Wilderness areas are always remote from roads

Explanation

The construct argument rests on the fact that landscapes labelled wilderness were frequently managed and inhabited by Indigenous peoples, so the idea of untouched nature reflects cultural assumptions. Declaring such land 'empty' obscures that history.

Question 18Outdoor and Environmental Studies

Which pairing of a hazard with its most appropriate control is correct for a coastal walk?

  1. Cliff edges - run quickly along the top to reduce exposure time
  2. Rock fishing on exposed ledges - check swell and tide forecasts and wear a life jacket Correct answer.
  3. Bushfire - carry a personal locator beacon as the only control
  4. Heat stress - wear dark, heavy clothing to block the sun

Explanation

Rock fishing is a high-risk coastal activity, and the main controls are checking swell and tide conditions and wearing flotation. These measures address the specific hazard of being washed from a ledge.

Question 19Outdoor and Environmental Studies

A group wants to compare the environmental impact of two meals for a hike: locally grown vegetables versus imported packaged food. Which analysis is most useful?

  1. Compare only the price per kilogram
  2. Choose whichever meal weighs less in the pack
  3. Count only the number of items in each meal
  4. Consider food miles, packaging waste and water used across the whole production and transport chain Correct answer.

Explanation

A life-cycle view accounts for transport, packaging and production inputs such as water, giving a more complete picture of impact. Looking at a single factor can mislead because impacts trade off across stages.

Question 20Outdoor and Environmental Studies

Why are riparian zones (land beside waterways) often the focus of restoration programs?

  1. They contain no introduced weeds
  2. They filter runoff, stabilise banks and provide habitat and shade for aquatic species Correct answer.
  3. They are unaffected by upstream land use
  4. They are always the cheapest land to buy

Explanation

Riparian vegetation intercepts sediment and nutrients, binds banks against erosion and shades the water, which supports aquatic life. Restoring these narrow strips delivers large benefits for catchment health.

Question 21Outdoor and Environmental Studies

Which statement best distinguishes conservation from preservation in land management?

  1. Conservation means total exclusion of people, while preservation encourages development
  2. Conservation allows sustainable use of resources, while preservation aims to protect areas from extractive use Correct answer.
  3. Conservation is a legal term, while preservation is a recreational term
  4. Conservation applies only to marine areas, while preservation applies only to forests

Explanation

Conservation is often defined as wise, sustainable use of natural resources, whereas preservation seeks to protect nature from consumptive use. The two ideas have shaped different park management philosophies.

Question 22Outdoor and Environmental Studies

A park agency proposes a new alpine resort development. Which framework would best allow a structured assessment of ecological, social and economic consequences?

  1. A financial audit of the developer's accounts
  2. A single-season count of one threatened species
  3. A survey of visitors asking whether they like resorts
  4. An environmental impact assessment covering cumulative effects, alternatives and mitigation Correct answer.

Explanation

Environmental impact assessment examines likely effects across ecological, social and economic dimensions, including cumulative impacts, alternatives and proposed mitigation. This gives decision-makers a balanced basis for approval or refusal.

Question 23Outdoor and Environmental Studies

Two groups debate the value of a remote wilderness area. One cites existence value, the other cites option value. Which statement correctly distinguishes them?

  1. Existence value applies only to species, while option value applies only to landscapes
  2. Existence value requires visiting the area, while option value requires harvesting from it
  3. Existence value is income from tourism, while option value is the cost of managing the area
  4. Existence value is benefit from knowing the area persists, while option value is benefit from keeping future use possible Correct answer.

Explanation

Existence value is the satisfaction people gain simply from knowing a place continues to exist, even if they never visit. Option value is the worth of preserving the choice to use it in future, for example keeping genetic or recreational options open.

Question 24Outdoor and Environmental Studies

A long-term study finds that a controlled burn every five years reduces fuel loads but lowers the abundance of a fire-sensitive shrub. Which conclusion is most defensible?

  1. The burn interval should be shortened everywhere to reduce fuel further
  2. Fuel reduction should be abandoned entirely
  3. A single burning interval creates trade-offs, so intervals should vary across the landscape to meet multiple objectives Correct answer.
  4. Fire-sensitive shrubs should be removed so burning can continue

Explanation

Fire regimes affect species differently, so one uniform interval produces winners and losers. Varying intervals and seasons across the landscape can maintain habitat for fire-sensitive species while still managing fuel in strategic areas.

Question 25Outdoor and Environmental Studies

Which scenario best illustrates the 'tragedy of the commons' as applied to a popular natural area?

  1. Many independent visitors each take small amounts of firewood, and collectively the fallen timber resource is depleted Correct answer.
  2. A community group replants a degraded reserve
  3. A council installs bins to reduce litter at a trailhead
  4. A single agency restricts access to protect a sensitive site

Explanation

The tragedy of the commons occurs when many users acting in their own interest collectively degrade a shared, unregulated resource. Each individual's small harvest seems harmless, but the aggregate effect removes the resource.

Question 26Outdoor and Environmental Studies

Which term describes the variety of living things within an ecosystem, including the range of species and the genetic differences between them?

  1. Biodiversity Correct answer.
  2. Carrying capacity
  3. Biomass
  4. Succession

Explanation

Biodiversity refers to the variety of life at all levels, including species richness, genetic variation and ecosystem diversity. Biomass measures the total mass of living material, succession describes change over time, and carrying capacity is the maximum population an area can support.

Question 27Outdoor and Environmental Studies

In minimum-impact (leave-no-trace) camping, which practice best reduces contamination of a waterway?

  1. Pouring wastewater into the stream where flow is fastest
  2. Burying food scraps in a shallow pit beside the bank
  3. Carrying water at least 50 metres away from the source before washing Correct answer.
  4. Washing dishes directly in the stream so food scraps float away

Explanation

Minimum-impact practice requires washing well away from water sources so that soap, food and pathogens do not enter the waterway. Soil and vegetation filter and break down the waste before it reaches the stream. Washing in or near the water delivers pollutants directly to the aquatic system.

Question 28Outdoor and Environmental Studies

Which of the following is a direct (extractive) use of a forested public land?

  1. Studying a forest food web for research
  2. Knowing the forest exists for future generations
  3. Photographing wildlife during a day walk
  4. Selective logging of timber for sawmills Correct answer.

Explanation

A direct extractive use removes a physical resource from the area for consumption or sale, such as harvesting timber. Wildlife photography, scientific study and existence for future generations are non-extractive uses because nothing is removed from the site.

Question 29Outdoor and Environmental Studies

Which natural hazard is most characteristic of bushwalking in the Australian Alps during winter?

  1. Heat exhaustion from extreme desert temperatures
  2. Cyclone storm surge
  3. Hypothermia from sudden cold, wet weather Correct answer.
  4. Flash flooding from monsoonal rain

Explanation

Alpine winter conditions bring rapid changes in weather, wind and precipitation, so exposure and hypothermia are the key hazards. Cyclones and monsoonal floods occur in tropical regions, and extreme desert heat is not an alpine winter hazard.

Question 30Outdoor and Environmental Studies

What does the term 'sustainability' most commonly mean in outdoor and environmental management?

  1. Maximising short-term visitor numbers to fund park management
  2. Protecting all areas from any human access
  3. Using resources at a rate that allows them to renew for future generations Correct answer.
  4. Removing introduced species from every ecosystem

Explanation

Sustainability means meeting present needs without compromising the ability of future generations to meet theirs, which requires use within renewal rates. It does not mean total exclusion of people, nor maximising short-term use, and pest removal is only one management action.

Question 31Outdoor and Environmental Studies

Which organisation is responsible for managing national parks in the Australian state of Victoria?

  1. The Bureau of Meteorology
  2. The Country Fire Authority
  3. Parks Victoria Correct answer.
  4. The Environment Protection Authority

Explanation

Parks Victoria is the statutory authority that manages national parks and other protected areas in Victoria. The Country Fire Authority handles firefighting on public land, the EPA regulates pollution, and the Bureau of Meteorology provides weather services.

Question 32Outdoor and Environmental Studies

Which survival principle best explains why a lost bushwalker should stop and stay put once others know they are overdue?

  1. Staying still guarantees rescue within one hour
  2. Staying put prevents all forms of injury
  3. Walking downhill always leads to a road
  4. Moving further increases the search area and reduces the chance of being found Correct answer.

Explanation

Searching is far easier when the missing person remains near the planned route, because wandering enlarges the search area and consumes energy and water. Staying put does not guarantee quick rescue or prevent every injury, and downhill travel does not reliably reach a road.

Question 33Outdoor and Environmental Studies

Which of the following is an abiotic component of an ecosystem?

  1. Kangaroos grazing grass
  2. Fungi decomposing leaf litter
  3. Eucalyptus seedlings
  4. Soil temperature and moisture Correct answer.

Explanation

Abiotic components are the non-living physical and chemical features of an ecosystem, such as temperature, moisture, light and soil minerals. Fungi, seedlings and kangaroos are living organisms and therefore biotic components.

Question 34Outdoor and Environmental Studies

A student records the number of bird species seen along three different tracks to compare their habitat value. Which limitation most affects the reliability of this comparison?

  1. The counts are a snapshot influenced by time of day and season Correct answer.
  2. Bird counts are not a recognised ecological indicator
  3. Tracks always have identical habitat
  4. Bird species cannot be identified without a laboratory

Explanation

A single survey is a snapshot, and bird activity varies with time of day, weather and season, so differences may reflect timing rather than habitat quality. Repeated surveys across similar conditions improve reliability. Birds can be identified in the field, and bird counts are widely used as indicators.

Question 35Outdoor and Environmental Studies

Which explanation best accounts for the high endemism of Australian native plants and animals?

  1. Australia has the highest rainfall of any continent
  2. Australia has been isolated as a continent for tens of millions of years Correct answer.
  3. Australian soils are uniformly volcanic and nutrient-rich
  4. Australia has never experienced natural climate change

Explanation

Long-term geographic isolation allowed Australian lineages to evolve separately, producing many species found nowhere else. Australia is mostly arid rather than the wettest continent, its soils are often old and nutrient-poor, and the continent has experienced major climatic shifts.

Question 36Outdoor and Environmental Studies

In an environmental impact assessment of a proposed trail, which step should occur before a decision is made about whether to proceed?

  1. Construction of the trail to test its popularity
  2. Public consultation and prediction of likely impacts Correct answer.
  3. Awarding the construction contract to a builder
  4. Setting entry fees for the completed trail

Explanation

Impact assessment is a predictive process that identifies likely environmental and social effects and invites public input before approval. Construction, contracting and fee-setting are implementation decisions that should follow, not precede, the assessment.

Question 37Outdoor and Environmental Studies

Which approach best reflects adaptive management of a heavily used coastal campsite showing soil compaction?

  1. Monitor compaction, trial a hardened camping pad, then review the results Correct answer.
  2. Ignore the compaction because visitors enjoy the site
  3. Close the site permanently and never reopen it
  4. Increase visitor numbers to spread the impact over a wider area

Explanation

Adaptive management treats actions as experiments: monitor the problem, implement a targeted intervention, then evaluate and adjust. This allows managers to learn from results while addressing the impact. Permanent closure is inflexible, ignoring the issue allows degradation, and adding visitors worsens the problem.

Question 38Outdoor and Environmental Studies

A national park is valued because people who will never visit it believe it should exist for its own sake. Which value does this describe?

  1. Option value
  2. Extractive value
  3. Recreational use value
  4. Existence value Correct answer.

Explanation

Existence value is the benefit people derive from knowing something exists, independent of any personal use. Recreational and extractive values require direct use, while option value reflects keeping the resource available for possible future use.

Question 39Outdoor and Environmental Studies

A fire-sensitive shrub species declines after frequent prescribed burning while a fire-dependent grass increases. What does this illustrate about fire regimes?

  1. All species respond to fire in the same way
  2. Prescribed burning always increases total biodiversity
  3. Different species have different tolerance to fire intervals Correct answer.
  4. Fire has no ecological role in Australian vegetation

Explanation

Species differ in life-history traits such as seed banks, resprouting ability and time to maturity, so the interval between fires favours some species over others. A regime that suits a fire-dependent grass can disadvantage a shrub that needs long fire-free periods to set seed.

Question 40Outdoor and Environmental Studies

Which strategy best reduces the spread of the root-rot pathogen Phytophthora cinnamomi in a national park?

  1. Encouraging visitors to walk through wet soil to spread their weight
  2. Planting susceptible species along all walking tracks
  3. Increasing vehicle access to remote wet areas
  4. Requiring boot and equipment cleaning at trailheads and keeping to formed tracks Correct answer.

Explanation

Phytophthora cinnamomi spreads in moist soil carried on boots, tyres and equipment, so hygiene stations and staying on formed tracks limit transport of infected soil. Planting susceptible species or increasing access to wet areas would expand the disease.

Question 41Outdoor and Environmental Studies

Which statement best describes the difference between a food chain and a food web?

  1. A food chain is always more realistic than a food web
  2. A food chain shows one linear path of energy flow, while a food web shows many interconnected paths Correct answer.
  3. A food chain includes decomposers, while a food web does not
  4. A food web shows only producers, while a food chain shows only consumers

Explanation

A food chain traces a single sequence of who eats whom, whereas a food web maps the many overlapping feeding relationships in a community. Because most organisms eat and are eaten by several species, the web is the more realistic representation.

Question 42Outdoor and Environmental Studies

A group plans a winter alpine hike and checks the forecast, carries a personal locator beacon and leaves a trip intention form. Which risk-management principle do these actions best demonstrate?

  1. Combining preparation, communication and emergency response Correct answer.
  2. Avoiding any planning because conditions change
  3. Transferring all responsibility to emergency services
  4. Relying on a single control to manage all hazards

Explanation

Effective risk management layers several controls: planning and weather awareness reduce exposure, a beacon enables response if something goes wrong, and a trip intention form aids search and rescue. Using multiple complementary controls is more robust than relying on one.

Question 43Outdoor and Environmental Studies

Which factor most strongly determines the type of vegetation community that develops at a given site?

  1. The colour of the local rock
  2. The names given to the area by explorers
  3. The number of visitors each year
  4. Climate, soil and disturbance history Correct answer.

Explanation

Vegetation communities reflect the interaction of climate, soil nutrients and structure, and disturbance regimes such as fire and grazing. Rock colour and place names have no ecological influence, and visitor numbers matter only where they cause disturbance.

Question 44Outdoor and Environmental Studies

A manager wants to know whether a revegetation project has improved a degraded site. Which monitoring design gives the strongest evidence?

  1. Anecdotal reports from passers-by
  2. A single photograph taken immediately after planting
  3. Measuring only the number of seedlings planted
  4. Repeated measurements of vegetation cover compared with an untreated reference site Correct answer.

Explanation

Comparing repeated measurements at the treated site with an untreated reference site controls for natural variation and shows change over time. A single photo or seedling count records effort rather than outcome, and anecdotes are not systematic evidence.

Question 45Outdoor and Environmental Studies

Which statement best explains why habitat fragmentation reduces population viability for small mammals?

  1. Small isolated patches support smaller populations with less genetic exchange Correct answer.
  2. Fragmentation always increases the total area of habitat
  3. Fragmentation increases gene flow between patches
  4. Edge habitat is always better quality than interior habitat

Explanation

Fragmentation divides habitat into smaller, isolated patches, so populations become smaller and gene flow between them is reduced, raising extinction risk. Fragmentation reduces rather than increases total habitat and gene flow, and edge habitat often differs from interior habitat in quality.

Question 46Outdoor and Environmental Studies

An agency must choose between two management options for a wetland. Which decision-making approach best integrates ecological, social and economic considerations?

  1. Selecting the cheapest option regardless of ecological effects
  2. Using a structured framework that scores ecological, social and economic criteria Correct answer.
  3. Deferring the decision until the wetland dries out
  4. Choosing the option preferred by the loudest stakeholder group

Explanation

Sustainability decisions require balancing ecological integrity, social acceptability and economic feasibility, which a structured multi-criteria framework makes transparent. Choosing on cost alone, on loudness of advocacy, or by indefinite delay ignores key dimensions of the problem.

Question 47Outdoor and Environmental Studies

A protected area is described as having high 'ecological integrity'. Which set of features best supports this description?

  1. Frequent soil disturbance and cleared boundaries
  2. High visitor numbers and extensive built infrastructure
  3. Native species composition, functioning processes and minimal human modification Correct answer.
  4. A single dominant introduced species and simplified food webs

Explanation

Ecological integrity refers to an ecosystem retaining its native composition, structure and function with little human modification. Heavy infrastructure, dominance by introduced species and widespread disturbance all indicate reduced integrity.

Question 48Outdoor and Environmental Studies

Two Indigenous ranger groups and a parks agency co-manage a protected area. Which feature most clearly distinguishes genuine co-management from consultation?

  1. The agency seeks opinions but retains all decision-making power
  2. The agency informs groups about decisions after they are made
  3. Decision-making authority and responsibility are shared between parties Correct answer.
  4. The groups are paid only to undertake weed spraying

Explanation

Co-management involves shared authority, responsibility and benefits in planning and decision-making, often formalised in agreements. Consultation, by contrast, seeks input while the agency keeps final authority, and contracting groups for a single task is not shared governance.

Question 49Outdoor and Environmental Studies

A popular natural area shows crowding, litter and trail widening during peak season. A manager proposes a booking system with a daily visitor cap. Which concept does the cap most directly operationalise?

  1. Recreational carrying capacity Correct answer.
  2. Ecological succession
  3. Endemism
  4. Trophic cascade

Explanation

Recreational carrying capacity is the level of use an area can sustain without unacceptable ecological or experiential decline, so a daily cap operationalises that limit. Succession and endemism are ecological concepts unrelated to visitor numbers, and a trophic cascade involves predator-prey effects.

Question 50Outdoor and Environmental Studies

A researcher argues that a 'pristine' wilderness area actually reflects thousands of years of Indigenous land management. Which evidence most directly supports this argument?

  1. The area has a high number of endemic plants
  2. The area contains no introduced species
  3. Historical records show deliberate burning that shaped vegetation structure and patchiness Correct answer.
  4. The area is far from the nearest town

Explanation

Evidence of deliberate, repeated burning that produced particular vegetation patterns shows that the landscape was actively managed rather than untouched. Distance from towns, absence of introduced species and endemism describe attributes of the area but do not demonstrate human shaping of it.
