Definition
In old English law, the head or branches of a tree that has been cut down. The related phrase coopertio arborum refers more specifically to the bark of felled timber trees together with the chumps (short thick sections of wood) and broken pieces of wood remaining after felling. The term belongs to the vocabulary of forest and woodland law, distinguishing between the usable timber of a tree and the incidental material — offcuts, bark, and broken wood — left behind after the main trunk was taken.
A related term, coopertura, denotes a thicket or covert of wood, and should not be confused with coopertio, which refers to the remnant parts of individual felled trees rather than a stand of living woodland.

Common Confusion
Coopertio and coopertura are easily conflated because of their orthographic similarity and their shared domain of forest law. They are distinct concepts: coopertio concerns the severed parts and debris of individual cut trees; coopertura describes a body of living woodland or thicket functioning as cover. Researchers encountering either term in medieval or early modern forest court records should verify which word appears in the source before drawing conclusions about the subject matter of a dispute or grant.

Why It Matters in Research
Coopertio surfaces almost exclusively in medieval English forest law and manorial records — court rolls, perambulations, grants of estovers, and proceedings before forest courts such as the Swanimote and the Court of Attachments. Researchers working in these materials need to recognize that rights over felled woodland were carefully parsed: the lord or crown might retain rights to the standing timber and the trunk while a tenant or commoner held rights to the loppings, bark, or broken wood. Coopertio and coopertio arborum represent precisely that lower stratum of woodland rights.
The term does not appear in post-medieval common law practice and is absent from equity and common law court records of the seventeenth century onward. Its appearance in a document is therefore itself a dating and classification signal, pointing toward manorial or forest administration rather than ordinary common law litigation.
Researchers should note that Cowell's Interpreter (cited by both Black's editions and by Rapalje & Lawrence) is the proximate source for the definition as it appears in the legal dictionaries. Cross-referencing Cowell directly will not yield additional substantive elaboration, but it confirms that the term was already archaic and dictionary-dependent by the early seventeenth century when Cowell wrote.
The distinction between coopertio (remnant parts of a felled tree) and the main timber was legally significant because different parties could hold rights to each. Misreading coopertio as a general term for timber or woodland cover could distort the interpretation of a grant or a forest court judgment.

Historical Dictionary Support
The three historical sources consulted are in close agreement, all tracing to Cowell as their authority. Black's first and second editions reproduce substantially identical language. Rapalje & Lawrence add the separate entry for coopertura immediately following coopertio, providing a useful contrast that neither Black's edition makes explicit.
None of the sources offer substantive elaboration beyond Cowell's brief statement, and none cite case authority. The definitions are descriptive rather than doctrinal, reflecting the antiquarian rather than the operative character of the term by the time these dictionaries were compiled. Researchers should treat the dictionary entries as glosses on a term they will encounter in primary sources, not as a statement of enforceable legal doctrine.
