What does this animal face?
A historically influential breed can become rare even when its descendants helped improve other sheep. Preserving Cotswold requires living purebred flocks, not simply documenting its past contribution. Older suggestions about Roman ancestry should be presented as possibilities, rather than as a continuous proven pedigree.
This is The Livestock Conservancy’s domestic-population category. It conveys conservation concern without supplying a head count. Its current list and an older breed-profile fact panel may differ; keep each label with its source.

Conservancy 2026 CPL report says US population is about half. Do not call this a dated census.
Read the source →These measures describe different dates, places and populations. They should not be added together or treated as a new census conducted by Conservation Legacy.
FAO’s DAD-IS keeps domestic breed information by country and maintains population-history tools. A useful statistic retains its date, geography and definition: breeding females, registrations, sampled animals and all living animals are different measures. A historical low point is meaningful history, but should not be presented as a current census.

One hundred animals.
Different breeding foundations.
Compare the same total with different numbers of breeding males and females. This simplified model illustrates why a head count alone cannot describe a population’s genetic future.
These are teaching examples, not estimates for the breed on this page. The formula assumes an idealized breeding population. Relatedness, unequal offspring contributions, changing numbers and overlapping generations require more detailed analysis. It does not predict a specific mating’s inbreeding or recommend a breeding plan.
Model basis: FAO, monitoring animal genetic resources (1992), section 4.2. Further guidance: FAO, In vivo conservation of animal genetic resources (2013).
