A bison in a meadow makes a magnificent photograph. The conservation story also needs less photogenic things: an identification number, a pedigree, a dated observation and a careful explanation of what has changed. This guide teaches 100 English vocabulary words and terms for bison conservation, with meanings, natural collocations and original examples for reading wildlife accounts accurately.
Poland is a useful setting because European bison recovery connects Białowieża, breeding records, protected landscapes and continuing questions about people and wildlife. Białowieża National Park explains both the animal and the European Bison Pedigree Book. These sources let us move beyond “there are more bison” towards questions about ancestry, range, monitoring and coexistence. Poland is not one habitat or one viewpoint, and conservation does not stop at a national border.
Choose a ten-word group, explain one relationship and then use the fictional movement register below to distinguish a birth from an arrival. “Top 100” is a curated learning selection, not a measured frequency ranking. Most entries are English; the Polish name żubr is labelled. The examples teach reading and communication, not animal handling, veterinary decisions or a plan for releasing wildlife.
Choose the question behind the bison photograph
Start with what the learner cannot yet explain. An unfamiliar word, a confused category and an unsupported conclusion require different kinds of practice.
More animals here: what kind of increase?
Begin with twelve counters representing a fictional herd. Move three counters in from another labelled area. Ask, “How many are here now, and how many births have we recorded?” The answers are fifteen and none. If the learner reports three births, the difficulty is not subtraction. It is the category of change. Teach arrival and birth together before adding a population-growth percentage.
Next show a family diagram in which several animals share grandparents. Ask whether a larger number of descendants automatically means a proportionately larger range of inherited variation. It does not. A learner can understand this first with a small family tree, before meeting the terms pedigree and genetic diversity. Avoid turning a genetic relationship into a claim that every related animal is ill.
Finally compare “not observed on today’s route” with “confirmed dead”. Ask what evidence separates them. If the learner understands the difference but cannot express it, practise one sentence: “The survey did not detect the animal; its status remains unresolved.” If the idea itself is unstable, use an ordinary missing-object example and return to the wildlife context after the distinction is clear.

Names carry different amounts of information. A common name may be broad, while a scientific name identifies the species intended by a source. The Polish word is useful when reading local labels, but most of this guide develops English.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 1 | European bison | The species Bison bonasus; distinguish it from the North American species Bison bison. | European bison conservation | The label named European bison rather than using buffalo as an interchangeable term. |
| 2 | wisent | An English alternative name for European bison; useful in historical and specialist writing. | wisent population | The catalogue explained wisent before using it throughout the account. |
| 3 | żubr | Polish, Latin alphabet: European bison; retain the letter ż, with no separate transliteration needed. | Polish żubr | The bilingual label translated żubr for readers unfamiliar with Polish. |
| 4 | species | A biological classification of organisms; its boundaries depend on the scientific context. | species identification | The species name clarified which bison the article discussed. |
| 5 | individual | One organism considered separately from a group. | identified individual | The individual received a record rather than becoming an anonymous addition to the total. |
| 6 | herd | A group of animals living or moving together; not automatically a whole biological population. | free-ranging herd | The herd photograph did not establish the size of the wider population. |
| 7 | bull | An adult male of certain large mammals, including bison. | adult bison bull | The register identified the bull separately from the calves. |
| 8 | cow | An adult female of certain large mammals, including bison. | adult bison cow | The example used cow for a female bison, not domestic cattle. |
| 9 | calf | A young individual of certain mammals, including bison; plural calves. | bison calf | The calf’s appearance in a photograph was not a complete birth record. |
| 10 | ruminant | An animal with a specialised digestive system that includes regurgitating and rechewing food. | large ruminant | The lesson explained ruminant without prescribing a diet for captive animals. |
Białowieża National Park distinguishes European and American bison on its species page. Use that source for the identity question. Buffalo, bison, wisent and żubr should not be shuffled merely to make an English paragraph sound varied.
A protected forest, a meadow and the route between them answer different ecological questions. A habitat description becomes useful when it identifies the organism, season and spatial scale concerned.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 11 | habitat | The environment in which an organism lives, considered in relation to its needs and activities. | bison habitat | The habitat description included more than the background of one photograph. |
| 12 | range | The geographical area occupied by a species or population, under a stated meaning. | historical range | The range account distinguished former occurrence from present observations. |
| 13 | home range | The area an individual or group regularly uses for normal activities. | seasonal home range | The home range estimate belonged to a defined period. |
| 14 | forest edge | The boundary zone between forest and a different adjoining habitat. | forest-edge habitat | The forest edge was described as a zone rather than a perfectly thin line. |
| 15 | meadow | An area dominated by herbaceous vegetation, often managed or used as grassland. | open meadow | The meadow was one part of the landscape comparison. |
| 16 | forage | Plant material available as food, or the act of searching for food. | available forage | The account named forage without assuming that all green plants were equivalent. |
| 17 | grazing | Feeding mainly on grasses and other low-growing vegetation. | seasonal grazing | The observation recorded grazing without making it the animal’s only feeding behaviour. |
| 18 | browsing | Feeding on leaves, shoots or woody vegetation in the relevant ecological sense. | bison browsing | Browsing was distinguished from grazing in the field description. |
| 19 | connectivity | The degree to which areas are linked for movement or ecological exchange. | habitat connectivity | Connectivity concerned the route between patches, not only their total area. |
| 20 | fragmentation | The division of habitat into smaller or more isolated patches. | habitat fragmentation | The map showed fragmentation that a national area total could conceal. |
Do not infer an animal’s full ecological needs from the word forest in a place name. Nor does a proposed corridor automatically establish safe movement. A real assessment needs local evidence, land-use context and the people affected.
Records connect a living animal with a history. These words help distinguish identity, location, ancestry and the date at which information was valid.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 21 | register | An organised official or working record of individuals or events. | animal register | The register recorded movements separately from births. |
| 22 | identifier | A code or other feature used to distinguish one record or individual from another. | unique animal identifier | The identifier connected the animal across two institutional records. |
| 23 | pedigree | A documented account of ancestry; not a claim of moral worth or human social rank. | recorded pedigree | The pedigree showed the animal’s documented parentage. |
| 24 | studbook | A managed register recording ancestry and other information for a breeding population. | conservation studbook | The studbook supported questions that a photograph could not answer. |
| 25 | parentage | The identity or relationship of an individual’s parents. | documented parentage | The report kept uncertain parentage visibly uncertain. |
| 26 | lineage | A line of descent through generations. | breeding lineage | The lineage description concerned ancestry rather than present location. |
| 27 | founder | An individual contributing to the ancestry of a population at its establishment. | founder contribution | The founder record helped explain why headcount and ancestry differed. |
| 28 | birth record | A record documenting a birth and its relevant identifying details. | verified birth record | The birth record was not replaced by a note saying the calf had arrived. |
| 29 | transfer record | A record of movement between places or custodial arrangements. | dated transfer record | The transfer record explained the increase at one site. |
| 30 | provenance | The documented origin and history of an animal record, sample or object. | sample provenance | The provenance connected the genetic sample with the correct identifier. |
The park’s Pedigree Book explanation distinguishes individual ancestry records from numerical recording of free and semi-free herds. Do not assume that every number in a population table carries a complete individual family tree. Read the table’s scope and reporting date.
Genetic vocabulary should clarify a relationship, not create a dramatic diagnosis. Population history can affect inherited variation, while the significance of a particular result requires specialist analysis.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 31 | genetic diversity | Variation in genetic material within a defined population or species. | population genetic diversity | A larger headcount did not automatically establish greater genetic diversity. |
| 32 | gene pool | The collection of genetic variants represented in a population. | population gene pool | The gene pool description concerned inherited variation, not a physical pool. |
| 33 | allele | One of the alternative versions of a genomic sequence at a particular location. | inherited allele | The diagram used allele to distinguish versions from whole organisms. |
| 34 | genotype | The genetic constitution at specified locations or across an organism, depending on context. | recorded genotype | The genotype was linked to a sample identifier. |
| 35 | inbreeding | Reproduction between genetically related individuals; its consequences depend on the population and traits. | population inbreeding | The discussion treated inbreeding as a relationship to analyse, not a visible diagnosis. |
| 36 | relatedness | The degree of shared ancestry or genetic relationship between individuals. | genetic relatedness | Relatedness could remain high even after the herd grew. |
| 37 | bottleneck | A sharp population reduction that can alter or reduce genetic variation. | population bottleneck | The bottleneck mattered to the later ancestry discussion. |
| 38 | founder effect | Changes in represented genetic variation when a new population is founded by a limited subset. | genetic founder effect | The founder effect concerned which variation entered the new population. |
| 39 | genetic drift | Random change in genetic-variant frequencies across generations. | population genetic drift | Genetic drift was not a deliberate management action. |
| 40 | effective population size | The size of an idealised population with comparable genetic-drift or inbreeding behaviour; not simply the census count. | estimated effective population size | Effective population size was distinguished from the number of animals counted. |
A pedigree can inform a genetic question without answering every one. A rising census count is encouraging within its scope, yet it does not by itself measure all aspects of genetic recovery. Avoid exact founder totals or present risk categories unless you have the appropriate dated source.
Conservation translocation has precise categories. Moving an animal, releasing it and demonstrating a lasting population are not synonyms. These definitions support reading, not practical wildlife-release instructions.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 41 | translocation | Deliberate movement of organisms from one place for release in another. | conservation translocation | The translocation proposal needed a stated conservation purpose. |
| 42 | reintroduction | Release intended to re-establish a species within part of its indigenous range from which it has disappeared. | bison reintroduction | The report checked former occurrence before calling the action reintroduction. |
| 43 | reinforcement | Adding individuals to an existing population under the relevant conservation framework. | population reinforcement | Reinforcement differed from establishing a population where none remained. |
| 44 | release | The act of allowing an animal out of controlled holding into a specified environment. | documented release | The release was an event, not proof of long-term establishment. |
| 45 | enclosure | A bounded area restricting movement. | breeding enclosure | The enclosure’s boundary mattered to the interpretation of the count. |
| 46 | free-ranging | Moving without continuous enclosure confinement, within the stated management context. | free-ranging bison | Free-ranging did not mean that all human influence had disappeared. |
| 47 | ex situ | Latin conservation term: outside the natural habitat or setting relevant to the conservation question. | ex situ conservation | Ex situ work was distinguished from monitoring a wild population. |
| 48 | in situ | Latin conservation term: within the natural habitat or setting concerned. | in situ conservation | The in situ discussion focused on the living landscape. |
| 49 | establishment | Persistence and functioning of a population after introduction or release, according to defined criteria. | population establishment | Establishment required evidence beyond opening a gate. |
| 50 | post-release monitoring | Observation after release to assess outcomes and relevant risks. | post-release monitoring plan | Post-release monitoring connected the initial event with later evidence. |
IUCN’s conservation-translocation guidance gives these actions a wider planning context. A vocabulary learner should be able to ask which category a source means and what evidence follows the release. Choosing actual animals, sites or procedures belongs to qualified, authorised work.
A population is not a photograph’s collection of visible animals. Keep the area, date, inclusion rule and type of change attached to every number.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 51 | population | A defined group of organisms considered together in a place, period or biological relationship. | defined bison population | The population statement identified the area it covered. |
| 52 | abundance | The number or amount of organisms in a defined context. | estimated abundance | Abundance was reported with the survey scope. |
| 53 | density | Number or amount per unit area or volume; state the relevant measure. | bison density | Density could not be calculated without an area. |
| 54 | census | An attempt to record all defined members of a population at a specified time or period. | population census | The census used an explicit inclusion rule. |
| 55 | recruitment | Entry into a defined population or stage; the operational definition must be stated. | population recruitment | The study defined recruitment before comparing years. |
| 56 | mortality | Death within a defined population and interval; a rate requires a time basis and denominator. | recorded mortality | Mortality was not inferred from every missing sighting. |
| 57 | survival | Continued life through a specified interval or condition. | post-release survival | Survival did not by itself establish reproduction. |
| 58 | immigration | Movement into a defined population or area. | recorded immigration | Immigration increased the local count without being a birth. |
| 59 | emigration | Movement out of a defined population or area. | recorded emigration | Emigration reduced the site total without being a death. |
| 60 | age structure | The distribution of individuals among age classes. | herd age structure | Age structure described something the total alone concealed. |
More animals at one site can reflect births, arrivals or a changed counting boundary. Fewer can reflect deaths, departures or incomplete observation. Name the process you have evidence for instead of letting a plus or minus sign tell the whole story.
A monitoring method can be useful without detecting every animal. Repeated images, independent observations and a new individual are different units of information.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 61 | monitoring | Repeated observation designed to track specified conditions or outcomes. | bison monitoring | Monitoring used a defined question rather than occasional impressions. |
| 62 | transect | A line or route along which observations are systematically made. | survey transect | The transect covered one part of the landscape. |
| 63 | sighting | An observation of an organism at a time and place. | verified sighting | The sighting did not automatically identify a new individual. |
| 64 | camera trap | An automatically triggered camera used to record animals or activity. | camera-trap image | The camera trap produced images that needed interpretation. |
| 65 | telemetry | Remote collection or transmission of measurements from an instrumented subject or site. | wildlife telemetry | Telemetry supplied a different kind of record from a tourist photograph. |
| 66 | track | A footprint or trace of movement; specify the sense when used as a noun. | bison track | The track was evidence of passage rather than a present headcount. |
| 67 | sampling effort | The amount and arrangement of work used to collect observations. | standardised sampling effort | Sampling effort had to be compared before interpreting different sighting totals. |
| 68 | detectability | The probability or practical likelihood of detecting an organism under stated conditions. | changing detectability | Detectability could change with the observation conditions. |
| 69 | double-counting | Counting the same individual or event more than once. | avoid double-counting | The review checked whether repeated photographs caused double-counting. |
| 70 | verification | Checking a claim or record against relevant evidence. | record verification | Verification connected the reported movement with its dated documentation. |
A photograph is a valuable observation, but three pictures of one recognisable animal are not necessarily three animals. Conversely, an empty camera image does not prove a species is absent from the whole area. Match the claim to the sampling method.
WORD GROUP 8 OF 10
71–80. Discuss care without turning the lesson into treatment advice
Health, welfare and population conservation are connected but distinct questions. These terms help a general reader understand a professional report without attempting to make clinical decisions.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 71 | welfare | The condition and experience of an animal in relation to its circumstances. | animal welfare | The report discussed welfare separately from the herd total. |
| 72 | health assessment | A structured evaluation of an animal’s health by appropriate professionals. | veterinary health assessment | The health assessment was not replaced by a confident look at a photograph. |
| 73 | quarantine | Separation under defined conditions to manage disease risk. | documented quarantine | The account named quarantine without supplying an operating protocol. |
| 74 | pathogen | An agent capable of causing disease in a susceptible host. | potential pathogen | The pathogen discussion required evidence rather than speculation. |
| 75 | transmission | The passing of an infectious agent between hosts or through an environment. | disease transmission | Transmission was distinguished from merely sharing a landscape. |
| 76 | biosecurity | Measures intended to reduce introduction or spread of biological hazards. | wildlife biosecurity | Biosecurity formed part of the professional planning context. |
| 77 | stress | A physiological or behavioural response to challenging conditions; interpretation needs context. | handling-related stress | The example named stress without diagnosing an actual animal. |
| 78 | habituation | A reduced response after repeated exposure to a stimulus. | human habituation | Habituation was not treated as the same thing as domestication. |
| 79 | domestication | A multigenerational process of population change under human selection and management. | animal domestication | Domestication differed from one animal becoming accustomed to people. |
| 80 | supplementary feeding | Provision of additional food under a management arrangement. | winter supplementary feeding | The reading treated supplementary feeding as a management question, not a visitor activity. |
An educational article should not tell readers to approach, feed or handle bison. Follow the responsible authority’s current rules and observe wildlife without attempting interventions. This vocabulary supports questions about a report; it does not certify the condition of a particular animal.
Coexistence is not achieved by declaring that everyone feels the same way. Reports can distinguish ecological aims, people’s experiences, evidence of damage and the process used to make decisions.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 81 | coexistence | People and wildlife sharing landscapes under conditions that allow continued living and functioning. | human–wildlife coexistence | Coexistence required attention to more than the number released. |
| 82 | stakeholder | A person or group with an interest in or affected by a decision. | local stakeholder | The account identified the stakeholder rather than speaking for everyone. |
| 83 | consultation | A process of seeking views or relevant information before a decision. | community consultation | Consultation was an activity to document, not a guaranteed agreement. |
| 84 | landowner | A person or organisation holding ownership of land. | affected landowner | The discussion distinguished a landowner from every other resident. |
| 85 | crop damage | Harm to cultivated plants, with extent and cause requiring evidence. | reported crop damage | The record distinguished reported crop damage from a verified claim. |
| 86 | mitigation | Action intended to reduce the severity or likelihood of a harmful effect. | conflict mitigation | Mitigation was described without promising to remove every difficulty. |
| 87 | compensation | Payment or another response intended to address a recognised loss under an applicable arrangement. | damage compensation | The example did not invent eligibility rules for compensation. |
| 88 | stewardship | Responsible care for a resource, place or living system over time. | landscape stewardship | Stewardship connected ecological care with continuing responsibility. |
| 89 | protected area | A defined area managed for conservation under a stated framework. | designated protected area | Protected area status did not mean that every activity was permitted. |
| 90 | management objective | A stated outcome towards which management actions are directed. | conservation management objective | The management objective made the later evaluation question clearer. |
Do not frame residents as a single obstacle or a single cheering audience. Farmers, visitors, researchers, foresters and other residents may face different questions. Attribute views to actual sources; the examples here invent no local testimony or compensation outcome.
The final terms help turn a wildlife story into a useful explanation. They travel well into school science, geography, public communication and the reading of numerical claims.
| No. | Word or term | Meaning and usage | Natural collocation | Original example |
|---|---|---|---|---|
| 91 | baseline | A defined starting reference for later comparison. | population baseline | The baseline preserved the original count and boundary. |
| 92 | trend | A pattern of change across an appropriate sequence of observations. | population trend | A trend needed more than two unmatched photographs. |
| 93 | uncertainty | A limit on how well a status, value or conclusion is known. | reported uncertainty | Uncertainty remained visible beside the estimate. |
| 94 | inference | A conclusion drawn from evidence beyond what is directly observed. | bounded inference | The inference did not extend the enclosure count to the whole country. |
| 95 | correlation | An association between variables, not by itself proof of a cause. | observed correlation | The correlation did not establish why the herd changed. |
| 96 | causation | A relationship in which one factor produces an effect under relevant conditions. | causal explanation | The causation claim required more evidence than a matching timeline. |
| 97 | recovery | Improvement from a depleted or impaired state, with the relevant criteria stated. | species recovery | Recovery was discussed through numbers, ancestry and persistence separately. |
| 98 | resilience | The capacity to withstand or recover from disturbance, under a specified definition. | population resilience | Resilience was not assumed from a large count alone. |
| 99 | qualification | A condition or limit attached to a claim; not an educational award here. | explicit qualification | The qualification stated that the figures concerned one fictional enclosure. |
| 100 | conservation outcome | A documented result relevant to a conservation objective. | measured conservation outcome | The outcome was distinguished from the action of releasing animals. |
A release is an action; survival is one possible outcome; a persistent population is a broader question. Good English makes those stages visible. It is possible to welcome a positive result while keeping the next question open.
Worked register: three arrivals, no recorded births
Original fictional register: Enclosure A holds twelve identified bison on 1 April. During April, three animals are transferred into A from another managed site. No births, deaths or departures are recorded. The closing register lists fifteen animals. The record supplies no genetic analysis, release event or country-wide census. These are invented figures for a language lesson, not Polish management data.
A weak summary says, “The herd reproduced successfully and grew by 25%, so the conservation programme has recovered the species.” The percentage increase in the enclosure total is arithmetically correct: three divided by twelve is 25%. Almost everything wrapped around it goes beyond the record. The new animals arrived by transfer; no births are documented. One enclosure’s numerical change cannot establish a species-wide outcome.
Begin with the accounting relationship: opening total plus arrivals minus departures, with births and deaths as separate categories. In this record, 12 + 3 = 15. A useful report is: “The registered total in Enclosure A increased from twelve to fifteen during April because three animals were transferred in. The record reports no births and does not assess genetic diversity or species-wide recovery.”
Changed condition: replace the transfer entry with three documented births; leave every other statement unchanged. The closing total and percentage increase stay the same. The explanation changes: the increase now reflects births rather than arrivals. This small change reveals whether the learner is reading the category or merely recognising familiar arithmetic.
Now add a different question: “Has genetic diversity risen by 25%?” The correct response remains that the headcount does not establish this. The ancestry and genetic evidence have not been supplied. A larger number of animals can be descended from a limited set of founders. Keep the missing question visible rather than inventing a genetic result to complete an upbeat story.
For an advanced transfer, change the reporting boundary from one enclosure to two sites between which the animals moved. A transfer within that combined boundary changes location but not the combined total. Ask the learner to redraw the boundary before calculating. The same event can increase a local count without increasing the population total used by a wider report.
Poland’s bison story has an archive as well as a landscape
The current Białowieża National Park species account is a useful starting point for distinguishing European bison from American bison. Its broader historical material should be read with its publication context rather than treated as a live population counter. This guide deliberately avoids repeating an undated present-day total.
The park’s European Bison Pedigree Book explanation gives a second reading route: how individual ancestry and numerical herd records support conservation knowledge. Ask which information identifies an animal, which describes its parents and which summarises a population at a reporting date. The page’s historical account explains why record continuity matters.
For historical context, Poland’s State Forests describes the return of free-living animals to the Polish part of Białowieża Forest in 1952. Keep the event distinct from later births, subsequent distribution and current management. A successful release date is not the date on which every conservation problem disappeared.
Białowieża is not the whole Polish landscape, and the forest itself is not contained entirely within Poland. Different sites have different ecological and human settings. A learner writing about “Polish bison” should specify whether the source concerns a species, a herd, a managed site or a particular part of the forest.
Illustrative dialogue: “There are three more animals. Were they born here?” “The register says they were transferred.” “Then what changed?” “The local total and the animals’ recorded location. The combined total across both sites may not have changed.” The exchange makes a numerical report more readable without making conservation less hopeful.
Choose the repair before choosing another list
A student who confuses herd and species needs a small classification task. A student who knows both but equates a transfer with a birth needs a movement register. A student who reads the register correctly but writes a sweeping national conclusion needs work on scope. Their next lesson should differ even if the first answer receives the same mark.
Parents can ask the learner to explain the counter demonstration in a familiar language, then help them find the English words for the categories they already understand. Record the first independent attempt. A supported correction is useful evidence of learning, but a later fresh record shows whether the relationship is available without the model.
Teachers can give three learners different jobs: identify the population boundary, classify each event and write the final summary. Rotate the roles on a new record so no learner becomes permanently the person who only counts. Then remove the table headings and ask for an independent explanation. Return to the first unstable distinction if the response collapses.
The published English Tuition | Poland guide connects a message with its exact source details and tests a changed condition. Apply the same habit here: preserve the total when it remains valid and revise the explanation when the event changes. The school and examination routes in that guide are separate from this wildlife vocabulary lesson; no eduKate centre in Poland is implied.
Practice: name the change before calculating
A. A photograph shows eight bison together. Does it establish the size of the whole species population? Give a more accurate description.
B. Twelve animals are present initially; three arrive by transfer; no other changes are recorded. State the closing total and the source of the increase.
C. Replace those arrivals with three documented births. Which numerical result remains, and which explanation changes?
D. The three animals moved between two sites included in one combined register. Does their movement alone increase that combined total?
E. A local count rises by 25%. Does that establish a 25% rise in genetic diversity? Name the different kind of evidence required.
F. A camera does not record an identified animal on one night. Rewrite “The animal died” so the conclusion fits the observation.
Answers and explanations
A. No. “The photograph shows a group of eight bison.” It does not supply a complete population boundary, date-wide census or detection method.
B. Fifteen animals are registered at the end. The three-animal increase reflects transfers into the defined site, not documented births.
C. The closing total of fifteen and the 25% increase remain. The increase now reflects births rather than incoming transfers.
D. No. Movement within the combined reporting boundary changes location, not the combined number. Other events would need separate records.
E. No. Ancestry or suitable genetic evidence is needed. Headcount and genetic variation are different quantities.
F. “The camera did not record the animal that night; the observation does not establish its survival status.” An absence from one record is not a confirmed death.
Use the vocabulary to explain a conservation record
Retrieve five terms without looking: herd, pedigree, transfer, reintroduction and recovery. For each, give an example and a nearby idea it must not be confused with. If a word remains vague, use its definition briefly, then hide the definition and try a new example rather than reciting the same one.
Write a 120–160-word report for a fictional school wildlife display. Identify the source, define the population boundary, explain one documented event and state one question the source does not answer. Keep invented exercise numbers labelled as invented. Use a Polish institutional source for the real contextual statement and do not invent a quotation from a local resident.
On another occasion, change the boundary or the category of movement. Ask the learner to revise only the affected claims and explain the revision aloud. This carries the words into science reading, geography, conservation communication and everyday numerical judgement. It does not turn a classroom exercise into a professional management assessment.
Frequently asked questions
Is żubr the same animal as American bison?
In Polish usage here, żubr refers to European bison, Bison bonasus. American bison is Bison bison. Keep the species identity explicit.
Does Top 100 mean these terms were counted in a corpus?
No. It is an editorial selection for useful reading, explanation and communication tasks.
Is a herd the same as a population?
Not necessarily. Herd describes a group, while population requires a defined biological or reporting scope.
Does a larger count prove full recovery?
No. The count is one measure. Ancestry, persistence, distribution and the stated conservation objectives can require separate evidence.
Does inbreeding mean every animal is visibly unhealthy?
No. It describes a genetic relationship. Consequences need appropriate evidence rather than a diagnosis from appearance.
Can I feed or approach bison after reading this guide?
No. This is a language guide, not animal-handling advice. Follow current official rules and leave wildlife management to authorised professionals.

Next: one event, one boundary, one accurate conclusion
If the categories are still tangled, return to the twelve counters and distinguish birth from arrival. If the categories are secure, change the reporting boundary. If both are secure, read a dated institutional table and identify which questions its numbers can and cannot answer.
