Definition
To convert land into a forest — specifically, to bring land under the legal regime of forest law, with all attendant royal rights, restrictions, and jurisdictions that designation entailed. The act was one of formal legal transformation, not merely ecological change: afforesting land subjected it to special courts, officers, and customs that governed hunting rights, timber use, and land occupation within the forest boundaries.
Common Language
Modern common usage (Wiktionary): To make into forest.
Historical common usage (Webster's 1913): To convert into a forest; as, to afforest a tract of country.
Editorial note: The gap here is significant. In ordinary usage, past and present, afforestation means planting trees or allowing woodland to develop — an environmental or agricultural act. In legal history, it meant something else entirely: placing land under the jurisdiction of forest law, a body of royal prerogative rights largely independent of the common law. Land could be "afforested" without being densely wooded, and wooded land could exist outside the legal forest. The ecological and legal meanings do not map onto each other.
Core Elements
To afforest land in the legal sense required:
- Royal authority: Afforestation was a prerogative act of the Crown. Private landowners could not afforest in the legal sense; only the king could extend forest law jurisdiction.
- Subjection to forest law: The affected land fell under the administration of forest courts (including the Court of Attachment, the Swainmote, and the Justice Seat) and forest officers (foresters, verderers, regarders).
- Restriction of common and proprietary rights: Existing landowners, tenants, and commoners within the newly afforested area faced severe limitations on their use of the land, including restrictions on assarting (clearing), purpresture (enclosure), and the right to hunt.
Why It Matters in Research
This term appears almost exclusively in sources dealing with English forest law and its constitutional history. Researchers will encounter it primarily in three contexts: (1) medieval records and chronicles concerning the expansion of royal forests under Norman and Angevin kings; (2) commentary on Magna Carta, particularly Chapter 47 of the 1217 reissue (the Forest Charter, or Carta de Foresta), which addressed the disafforestation of lands afforested by Henry II; and (3) treatises on English real property history.
The critical research trap is importing the modern environmental meaning. When a historical source says land was "afforested," it describes a jurisdictional event with legal and economic consequences for affected landowners — not a landscaping decision. Burrill's entry includes the Latin passage from Magna Carta's Forest Charter provisions, which is a useful pointer to the constitutional dimension of the term.
Researchers using this term as a search string in historical corpora should note that the Latin forms — afforestare, aforestare — appear frequently in original documents and their early translations. The English verb form afforest is largely a product of legal commentary and treatise writing. The inverse term, DISAFFOREST (or DEFOREST), will often be more prominent in the same sources, as the political pressure of the thirteenth century ran toward rolling back royal forest claims rather than expanding them.
Historical Dictionary Support
All four source dictionaries agree on the core definition — conversion of land into a forest in the legal sense — with little divergence. The entries in Black's (both editions) and Rapalje & Lawrence are spare to the point of being unhelpful without background context. Burrill's is the most useful of the shelf sources here: it supplies the Latin form, a cross-reference to Spelman's glossary, and the Magna Carta passage, which anchors the term in its constitutional moment.
What the historical dictionaries collectively miss is any explanation of why the legal meaning departs so sharply from the ordinary one, or what the practical consequences of afforestation were for affected landowners. They treat the term as self-explanatory to a reader already immersed in forest law. Modern researchers lacking that background will find the dictionary entries insufficient on their own.
Jurisdictional Note
Afforest, in its legal sense, is a term of English law with no direct counterpart in American legal history. Colonial and American law did not adopt the English forest law system. Researchers working in American property or land use history will encounter the term only in historical background material concerning English antecedents.
