A forest stands above limestone, a river cuts ancient sediment layers, and a small fossil bed records life in a lost environment. A visitor may see only scenery. Geodiversity asks what the rocks, soils, landforms, water and natural processes reveal—and what must be managed to protect their physical history.
The gold standard of geodiversity is a scientific inventory that distinguishes physical variety, heritage significance and responsible geoconservation. This guide explains eighteen fundamental controls, five original teaching cases, frequently asked questions and the connected eduKate library of Earth and conservation sciences.
Part of The Gold Standard. This phrase refers to an editorial benchmark, not UNESCO designation, legal protected-site status or a certified environmental assessment.

1. The landscape is more than scenery
Geodiversity describes the natural variety of rocks, minerals, fossils, soils, landforms, water features and geological processes. It is the nonliving part of nature, closely interacting with biodiversity. A field may contain several hidden geological units even when vegetation makes it appear uniform. Conversely, one impressive mountain does not automatically make a region richer in every geodiversity measure.
IUCN recognises geological and physical diversity as important to natural systems and heritage. A useful assessment begins with a declared study area, purpose and evidence sources. The gold standard is a record of the physical landscape whose classifications and uncertainties can be reconstructed, not a contest for the most photogenic location.
2. Separate geodiversity from geoheritage
Geodiversity includes the entire range of physical nature, while geoheritage concerns particular features recognised for scientific, cultural, educational or other significance. Geoconservation involves caring for geological heritage and its supporting processes. The concepts overlap, but they answer different questions.
An ordinary rock formation contributes to geodiversity even if it lacks rare heritage value. A small fossil exposure may be highly significant although it covers little area. IUCN’s 2020 protected-area geoconservation guidelines address the importance of evaluating sites and processes together. When a ranking is made, publish the criteria and explain which judgements represent scientific observations versus decisions about value.
3. Describe rock units with traceable maps
Rock type, age, composition and geological history influence landscapes and their features. A geological map may depict an entire formation under one colour even though several lithologies occur inside it. Another map may subdivide the same rock sequence into finer units. A comparison of class counts becomes misleading unless those schemes are reconciled.
Record map scale, original field observations, survey year and confidence in boundaries. Separate visible outcrops from rock inferred beneath soil or buildings. A newly digitised map can look more detailed without containing new geological observations. Readers need to know whether apparent diversity changed in nature or only in the way the units were described.
4. Include minerals and formations without inventing commercial value
Mineral occurrences can help reconstruct how rocks formed and changed under geological conditions. Their appearance alone is not proof of identity, economic value or heritage significance. A mineral vein may require chemical or structural tests, while the age and relation to surrounding rock can be essential to its scientific interpretation.
An inventory should document source location, mineral evidence and context. Rare minerals may justify special stewardship, but a deposit is not necessarily viable for extraction. Likewise, a common mineral can play a central role in soil and water chemistry. Scientific value, commercial feasibility and conservation priority must be evaluated separately.
5. Protect fossils and their original context
Fossils connect physical geological settings with the history of life. Their scientific meaning depends on their placement in rock layers, preservation and relation to other evidence. Removing a specimen without recording context can weaken its ability to explain past conditions.
Fossil sites may have legal, cultural or scientific access restrictions. Geodiversity management should protect sensitive exposures and provide lawful routes to research and education. A museum specimen, a fossil cast and an original in-situ fossil serve different purposes, and public displays must identify which is being presented. A protected locality should not be promoted with coordinates that encourage unauthorised collecting.
6. Read landforms as evidence of processes
Valleys, dunes, terraces, caves, volcanoes and coastal features record relationships among rock, water, wind, ice, tectonics and time. Their shapes can be described using terrain measurements, but geometric resemblance does not prove the mechanism that produced them. A flat terrace may have several geological explanations.
Compare elevation data with sediment, field geology and historical evidence. Document which features are measured and which interpretations are provisional. Natural erosion can create and maintain landforms, while human infrastructure can alter them. Geomorphology explains these histories; geomorphometry helps quantify the forms. Both contribute to a credible geodiversity assessment.
7. Treat soil variation as part of physical diversity
Soils vary by parent material, mineral composition, texture, hydrology, climate and history. They also interact with living communities, making the soil profile a bridge between geodiversity and ecology. An urban site with imported fill may have a different soil history from the underlying bedrock.
Use actual soil profiles and survey methods, not simply the closest geological polygon. A soil type does not by itself prove agricultural fertility, contamination or foundation suitability. These questions require appropriate specialist evidence. For conservation, the relevant value may include unusual horizons, geomorphic history or the soil’s role in supporting distinctive habitats.
8. Follow water and sediment beyond site boundaries
Springs, streams, wetlands and coastal processes connect physical features across a landscape. A geological exposure may depend on an eroding riverbank, while a protected spring may depend on recharge far outside its visible boundaries. Managing only the object without the process can fail.
Map relevant catchments, aquifers, sediment pathways and seasonal changes. A barrier that stabilises one stream section may change downstream deposition. A conservation intervention should explain the broader consequences of altering water and sediment. Site polygons and geological process boundaries are different entities and should not be substituted for each other.
9. Use site significance criteria that can be examined
Geoheritage assessment can consider rarity, representativeness, scientific integrity, educational potential, cultural value and vulnerability. These factors may point to different priorities. A robust teaching outcrop can deserve protection despite being common, while an irreplaceable fossil bed may be too fragile for public access.
Publish each criterion, its evidence, relative priority and who participated in judgement. Avoid compressing conflicting values into an unexplained number. If local cultural associations affect access or naming, respect legitimate rights and context. Scientific rarity does not automatically override every other interest.
10. Use UNESCO geopark designations accurately
UNESCO Global Geoparks connect geological heritage with sustainable development, education, communities and broader natural and cultural values. Formal designation follows UNESCO’s programme requirements; geological beauty by itself is not sufficient. The UNESCO list updated in June 2026 recorded 241 Global Geoparks in 51 countries.
A geopark is not automatically governed by the same legal protection for every individual feature. Check the particular site’s status, custodians and legal duties. Distinguish a proposed geopark, nationally recognised area and UNESCO Global Geopark. Public articles should never invent recognition or imply it means unlimited permission to visit or collect.
11. Apply IUCN geoconservation guidance within its scope
IUCN’s 2020 guidelines discuss conserving geodiversity and geoheritage in protected and conserved areas. They connect geological features with living ecosystems and management challenges. The guidance informs best practice but is not a universal substitute for national law, engineering rules or landholder rights.
Review which features are to be protected, how access is governed, what active processes matter and which threats are preventable. Some sensitive sites may need limited professional access, while durable locations can support public education. Good stewardship is driven by purpose and evidence rather than the assumption that more signs, fences or paths always improve conservation.
12. Map diversity using appropriate spatial scales
A landscape inventory may combine geology, terrain models, soils, hydrology and imagery from different periods and resolutions. A 10-metre raster produced from kilometre-scale mapping does not create 10-metre geological survey precision. Interpolation and classification can also alter the visible number of mapped features.
Record the source, date, resolution, coordinate reference and mapping method of every input. Compare similar geological classes under consistent rules. Test important locations against independent observations where possible. A clear map legend should distinguish observed geology from inferred boundaries and analytical categories. This makes the result suitable for correction rather than merely attractive.
13. Measure variety without confusing it with value
A simple geodiversity index might count different landform or rock classes, while a weighted approach might give higher importance to rare or scientifically valuable features. Both depend on choices about scale and classification. More named map units do not necessarily mean that a landscape physically became more diverse.
Compare classifications and investigate sensitivity before asserting differences between areas. A rare site can deserve protection even if it changes the regional count only slightly. Conversely, a broad variety score cannot establish that visitors understand the geology or that sensitive locations are well managed. Metric and policy goals must stay separate.
14. Preserve dynamic geological processes
Some valued features depend on continuing erosion, sediment transport or groundwater flow. Freezing every riverbank, dune or coastline in place can remove geological functions the conservation programme seeks to preserve. But natural movement can also pose risk to people or important infrastructure.
Management should distinguish process conservation from public safety. Use appropriate hydrological, geological and hazard investigations rather than assuming all natural change is beneficial or harmful. A protected cliff may retain scientific value through gradual exposure of layers, while public access requires separate controls. Long-term stewardship needs to account for change instead of rewarding only a static photograph.
15. Connect geodiversity with ecological diversity carefully
Rock, soil and landform variation affects microclimates, water availability and habitat conditions. These can influence plants and animals, but geological richness does not automatically imply higher species abundance under every circumstance. Climate, migration, disturbance and management also shape biodiversity.
Where an environmental report claims an ecological effect, identify the species or habitat observations supporting it. A geodiversity map alone is not a biodiversity survey. Similarly, planting every exposed rock surface can hide valuable strata while increasing a vegetation indicator. Responsible conservation recognises both dimensions and tests trade-offs with suitable evidence.
16. Include hazard, extraction and visitor pressures
Quarrying, development, uncontrolled fossil collecting and visitor damage may degrade geosites, while volcanic activity, erosion and rockfall can be natural geological processes with safety consequences. A conservation assessment should identify the physical mechanism and relevant authority before choosing actions.
Separate scientific value from resource value, and separate long-term hazard from real-time safety warnings. A mining project might expose new geological sections while simultaneously destroying irreplaceable evidence elsewhere. A public trail might increase education but threaten a fragile layer. Decisions require comparison of alternatives and explicit accounting for long-term costs and community effects.
17. Protect community and cultural connections
Mountains, springs, caves, stones and cliffs can carry meanings beyond their geological description. Indigenous and local custodians may have legitimate rights relating to access, names, knowledge and publication. Their observations can also support understanding of landscape history, but should not be extracted without appropriate consent.
Invite meaningful participation when establishing site significance and management. Identify information that should remain restricted, such as sensitive cultural places or vulnerable fossil localities. Scientific mapping ability is not automatic permission to disclose everything. A sustainable geodiversity programme must maintain both physical evidence and respectful governance.
18. Monitor condition and transfer stewardship
Long-term protection requires repeat observations, management records and responsibility that persists when personnel change. Surveys may record erosion, damage, water conditions, visitor pressure and the state of key exposures. Their quality depends on comparable methods and a clear baseline.
A single increase in detected damage may reflect better inspection rather than deterioration, so reports need sampling coverage and context. Managers should preserve source photographs, access rules, interventions and revisions. The gold standard is a geodiversity record future teams can understand, update and use to explain why conservation decisions were made.
Five worked fictional field cases
Worked case A: class counts change when the legend changes
Two fictional teams map the same land. The first recognises eight rock units. The second subdivides two formations, producing twelve units without any new geological process occurring. The count rises by four, or 50% relative to the original eight. That difference represents classification detail, not necessarily new geodiversity.
An honest comparison would reconcile the lithological and stratigraphic definitions before measuring change. All numbers are invented and do not identify any actual rock formation.
Worked case B: a geosite depends on a river outside its boundary
A fictional protected cliff exposes sedimentary layers because a river periodically erodes its base. An upstream channel project changes flow and sediment supply while the protected boundary remains unchanged. Keeping a legal polygon intact does not establish that the process sustaining the site survives.
A review needs a catchment-scale physical model, conservation purpose, hazard assessment and suitable alternatives. It should not assume that either unlimited erosion or complete stabilization is always best.
Worked case C: a visitor trail versus a fossil bed
An imaginary heritage route passes a fragile fossil exposure and a durable nearby outcrop. Sending visitors directly onto the fossils could increase attendance while damaging the scientific record. A supervised research area paired with accurate replicas and interpretation elsewhere could offer a different balance.
Assess education, accessibility, site damage, costs, legal permissions and community relationships. A replica must be labelled as a replica. The correct answer cannot be determined from ticket sales alone.
Worked case D: percentages conceal inspection coverage
A fictional reserve checks 40 observation points in one year and finds four with new damage, a 10% observed rate. The next year it checks 60 points and finds six, again 10%. An increase from four to six affected points does not prove damage risk increased, because the inspection coverage grew.
The manager should examine site comparability, severity, timing and sampling decisions before drawing conclusions. Both figures are invented teaching arithmetic.
Worked case E: restoration benefits can conflict
A fictional project plans to increase vegetation cover across a former quarry. One small exposed contact contains important geological evidence. Covering every rock face may increase a satellite greenness index while making that contact inaccessible to researchers.
An alternative might protect the exposure and restore vegetation elsewhere, subject to engineering, ecology and community review. One environmental score cannot replace the separately measured geological and ecological objectives.
Geodiversity stewardship and editorial audit
- Keep raw geological observations and inferred boundaries separate.
- Record rock and soil classifications before comparing diversity counts.
- Verify whether geosite designation and collection permissions exist.
- Connect water, erosion and sediment with landscape features.
- Assess physical risks and cultural or ecological trade-offs.
- Report significance criteria and visitor management outcomes.
- Make source evidence and long-term monitoring reproducible.
Applied geodiversity fieldwork and stewardship decisions
The survey that counted more because it mapped more
One hypothetical park is assessed at 1:100,000 scale and a neighbouring park at 1:10,000. The detailed study distinguishes several mineral and landform subtypes that the regional survey combines. A raw class-count comparison could make the second site appear naturally richer, even when neither has been observed under comparable methods. The first question is whether the datasets measure the same level of variation.
A meaningful comparison would harmonise classes or present complementary metrics, then compare selected locations with independent field evidence. A map is a model whose categories are selected by researchers, not a transparent window onto nature. The inventory should preserve its original resolution and explain whether a change in diversity represents additional observations or actual alteration of the landscape.
The small geosite invisible to a regional index
An imagined rocky valley contains extensive common sandstone and one small exposure showing an unusual contact between formations. A coarse geodiversity index may be dominated by the area occupied by the sandstone and barely register the contact. Yet the contact could hold significant value for reconstructing regional geological history or teaching how different rock units meet.
The assessment should report site-specific significance alongside broader landscape metrics. Rarity, scientific integrity, accessibility and vulnerability need distinct consideration. A conservation policy designed solely to maximise a region-wide category-richness score might miss the small feature entirely. A systematic site inventory and geological reasoning provide evidence that a raster summary cannot replace.
When geological heritage and biodiversity objectives collide
A fictional former quarry supports new pioneer vegetation and contains an exposed stratigraphic sequence useful for research. A restoration plan proposes covering the entire exposed face with substrate and planting. That might increase vegetation cover while erasing access to the rock record. The reverse choice—keeping the whole quarry bare—might also fail legitimate ecological objectives.
A responsible plan could identify the minimum scientifically relevant exposure, evaluate safety and other habitat needs, then designate appropriate areas for planting and research. Qualified geologists, ecologists, engineers, rights holders and local managers would assess the alternatives. Geodiversity and biodiversity support one another in many settings, but their measures are not interchangeable and neither can be assumed always to dominate.
A spring’s protected fence is not its catchment
Imagine a striking mineral spring inside a small conservation reserve. Water chemistry and fracture mapping suggest that its recharge occurs far beyond the fence. A land-use proposal elsewhere in the catchment could change its flow or water quality despite leaving the visible spring untouched. Geoconservation focused only on the outlet would neglect the processes maintaining the feature.
A sound investigation would review hydrogeological connections, seasonal variability, source-water quality and uncertainty. It should not assert one exact underground route without appropriate evidence. The physical catchment, legal boundaries and responsible authorities must be distinguished. A protected-site label is meaningful but does not automatically preserve every external process on which that site depends.
The cliff face that changes through natural erosion
A geological cliff can lose material as waves, wind or rainfall act upon it. New strata may become visible while older exposed sections disappear. Describing every change as conservation failure would ignore the natural dynamics that create the feature. Equally, unchecked public access could produce damage or expose visitors to unacceptable hazards.
The management plan should define which geological evidence matters, how erosion behaves and what safety and legal obligations apply. Repeat surveys can document change at comparable points, while qualified hazard assessments determine permitted access. A static image is a poor long-term target for a landscape whose significance includes active processes. Decisions should focus on protecting scientific value and people rather than freezing scenery in place.
An attractive mineral deposit without enough identification
A coloured mineral vein appears in a rock face and is presented in a tourism leaflet as a rare economic resource. The photograph may support the vein’s appearance, but not a complete mineral identification, grade or economic feasibility assessment. Similar colours can arise from several minerals or surface weathering products.
A credible account documents geological setting, relevant laboratory evidence, uncertainty and any historical use. It separates mineral occurrence, scientific interest and commercial evaluation. Collecting restrictions and land rights also require checking. An educational author should not turn one field photograph into claims about valuable ore reserves or suggest visitors remove samples. The most useful story may be the vein’s formation rather than its speculative price.
Historic fossils and missing contextual evidence
An old collection contains a distinctive fossil with no reliable record of its original layer or location. Its physical morphology may still support some scientific analysis, but a statement about the precise environment where it lived would require missing contextual information. The age and regional setting cannot automatically be inferred from an unsigned display label.
A careful catalogue preserves what is known, what was inferred and which sources were consulted. Later researchers may be able to improve provenance through historic collection records, but they should not invent certainty. This example illustrates why field notes, specimen identity and stratigraphic position are parts of the scientific asset. A visually complete museum display cannot compensate for lost evidence by pretending the unknown is known.
Soil diversity across a short forest trail
Two points only a short distance apart may differ in drainage, parent material and soil horizons. A general geological map may depict both under one bedrock unit. If the study’s purpose is to understand soil-related physical diversity, a local soil survey can reveal meaningful detail. Yet the soil differences alone do not prove that different plant communities must occur at each point.
The analysis should document the depth, method and conditions of observations, and compare them with hydrology and ecology where the question requires it. One hand sample or a colour photograph cannot determine all soil properties. Good geodiversity education explains that soils are physical and biological interfaces without collapsing soil science into either a geology-only or vegetation-only map.
A UNESCO label must be verified, not inferred
An article describes a dramatic volcanic landscape as a UNESCO Global Geopark because it appears in a travel brochure using the word ‘geopark’. Formal UNESCO status requires an actual recognition process and appears on the programme’s official list. Local naming, national protection and international designation are separate matters.
Editorial checks should verify the exact location, name and current status with authoritative sources. The writer should not imply that designation means all geological features are publicly accessible or that collecting is allowed. Such permission depends on the site’s actual rules. Accurate descriptions help travellers and students appreciate conservation while avoiding confusion between scientific value, branding and legal governance.
Dynamic dunes under a proposed visitor route
A dune field changes as wind moves sediment and vegetation modifies its stability. A fixed boardwalk might reduce trampling at one location while affecting sediment movement or requiring maintenance as the surface shifts. The right design depends on intended access, qualified geomorphological assessment, safety and the dune’s ecological roles.
A conservation review would record landform change over time and compare visitor impacts with natural variability. It should not treat movement of dunes as a failure to maintain the original outline. A dynamic protected landscape needs decisions that can adapt to physical processes and changes in public use. An initial route plan should include future monitoring rather than assuming one alignment remains suitable forever.
Quarry rehabilitation and the value of original exposures
A disused quarry may contain exposed geological structures that are normally concealed beneath soil. Restoration for public safety, water management and habitat is important, but full infilling can erase scientific evidence. The existence of an exposure, however, does not make an unsafe excavation automatically acceptable for public entry.
A responsible plan would identify which features carry scientific value, which must be stabilised or excluded from access and how rehabilitation can meet environmental and safety duties. A protected section might be documented for future research while surrounding areas are treated differently. The conclusion needs professional evidence and legal approvals, not an ideological preference for either bare rock or planted ground.
Visitor numbers and conservation outcomes are different
A geological visitor centre opens and attracts twice as many visitors as the previous informal trail. The growth may be economically and educationally meaningful, but it does not show that rock exposures are in better condition or that visitors learned accurate science. More visitors can increase the need for maintenance or controls.
Evaluate separate measures: access, comprehension, site condition, local benefit and costs. Test the interpretation with representative visitors rather than counting brochures distributed. Damage monitoring needs consistent coverage and severity definitions. If the site is fragile, visitor success may include appropriate redirection away from sensitive areas rather than universal physical access to every feature.
Uncertainty on a map is not a flaw to conceal
A geologist maps a contact confidently in several outcrops but can only infer its course beneath vegetation between them. The resulting digital line can be drawn smoothly, yet its exact position remains uncertain over part of the route. If the line is displayed identically everywhere, later users may assume a survey accuracy that was never achieved.
Represent observed, approximate and inferred sections with appropriate attributes and symbols. Preserve supporting field notes and map scale. A site-level construction or hazard decision may need additional investigation. Transparent uncertainty makes the map more useful, not less; it tells a competent reader what question should be investigated next.
Geodiversity and groundwater source protection
A region with unusual geology may contain springs, fractures or aquifers that also provide important water supplies. Mapping geological variety can highlight physical conditions, but it cannot by itself establish the contamination risk of a well or the amount of sustainable groundwater available. Those require hydrogeological and water-quality analysis.
A conservation plan should identify where protecting a geological feature overlaps with maintaining water recharge or river function. The relevant authorities may differ from those responsible for geoheritage. The boundary of the protected outcrop and the zone affecting the water source may also differ. A shared landscape requires coordinated evidence without making one map answer every question.
Monitoring counts without stable sampling effort
Suppose one year a reserve inspects 50 locations and later inspects 100. A larger number of damaged sites may simply reflect the expanded coverage. A fair monitoring programme should report the number examined, their selection, severity of observed damage and which locations remained comparable between years.
Where the selection changed, preserve separate results rather than presenting a naive trend. Field teams should document weather, access, visitor conditions and methods. A high-priority fossil exposure may matter more than several superficial marks on a durable path. A good condition assessment measures the significance of change, not only the number of checked boxes.
Community stewardship beyond the launch ceremony
A new protected geological area is announced with signs and a visitor map, but the programme has no recurring funds for inspections or repairs. The absence of a maintenance plan may affect safety, the quality of interpretation and protection of sensitive evidence. A designation is a governance milestone rather than the final conservation result.
Set accountable roles for geological review, access, education, incident response and data correction. Include community participation appropriate to the setting and plan for changes in land use or infrastructure. Transparent budgets should separate one-time construction from ongoing obligations. A conservation programme survives when its knowledge and responsibilities remain usable after the initial project team leaves.
Why a geodiversity index needs version control
An index used for national reporting may be recalculated after a geological map is revised, a new soil classification is issued or a better terrain dataset becomes available. A change in the reported score can therefore be a measurement update rather than a physical change. An accountable programme records its old and new input versions, explains classification differences and, where useful, reruns earlier years under a consistent updated method to obtain a comparable series. The original reported figures should remain traceable.
This distinction matters for policy evaluation. A newly mapped rock formation is not necessarily a newly formed geological feature. By separating information improvement from landscape alteration, scientists can make credible statements about both. A report that silently replaces an old score may make genuine conservation progress impossible to evaluate.
What to do when conservation and public access conflict
A geosite may support school visits while containing unstable rock faces, fragile fossils or culturally sensitive areas. Managers need not choose blindly between unrestricted access and total closure. They can compare supervised viewing, durable interpretation zones, digital resources, appropriate exclusion areas and other options within local safety and legal conditions. The choices should be based on the actual site’s values and risks.
Monitoring should then distinguish access quality, learning, geological condition and any incidents. A high visitor satisfaction score is not a geological integrity measurement, and a low visitor count does not mean preservation has failed. Explicit objectives allow several legitimate uses to coexist without conflating them.
A responsible response when field evidence contradicts the old map
A new borehole, erosion event or field survey may reveal that a mapped geological contact lies elsewhere or that a deposit has been misclassified. The evidence should be assessed through appropriate scientific review rather than hidden because a previous conservation plan relied on the map. Record the earlier interpretation, new observations, uncertainty and approval of the correction.
Update affected educational materials and site management when the change matters. Some past conclusions may remain valid, while others need reconsideration. This ability to revise the geological record is a strength of responsible science. A geodiversity assessment is most valuable when future workers can challenge it without losing its provenance.
Frequently asked questions
What is geodiversity?
Physical natural diversity, including rocks, minerals, fossils, soils, landforms, water and geological processes.
Is geodiversity the same as biodiversity?
No. The first concerns physical nature; the second living variety, although they interact.
What is geoheritage?
Geological features recognised for special scientific, educational, cultural or other value.
What is geoconservation?
Stewardship of geological features and the processes important to their continued value.
Are all scenic places UNESCO Global Geoparks?
No. Formal status follows the UNESCO programme and official published list.
Do diversity indices prove conservation success?
No. They depend on definitions and mapping scale and do not measure every condition or outcome.
Can fossils be collected anywhere?
No. Many places have legal, cultural and scientific restrictions.
Can natural erosion support conservation?
Yes, where dynamic processes sustain features, while safety still needs management.
Does geology predict species richness automatically?
No. Ecosystems depend on many other factors and require separate observations.
Why do local custodians matter?
Their rights, meanings and knowledge can be central to responsible site management.
Is a high-resolution map automatically accurate?
No. Resolution and source accuracy are different.
What defines a good assessment?
Transparent inventory, field evidence, appropriate scale, significance criteria, uncertainty and governance.
