A more thorough explanation:

Viridario eligendo is a legal term that refers to a writ used to choose a verderer in the forest. A verderer is a person who is responsible for managing and protecting a forest. The writ was used in medieval times to ensure that the verderer was chosen fairly and impartially.

One example of the use of viridario eligendo can be found in the Forest Charter of 1217. This charter was issued by King Henry III of England and granted certain rights to the people who lived and worked in the forests. One of these rights was the right to choose a verderer through the use of a writ called viridario eligendo.

Another example can be found in the Forest Law of 1662. This law established a system for managing the forests of England and included provisions for the selection of verderers through the use of viridario eligendo.

Viridario eligendo was an important legal tool in medieval England for ensuring that the forests were managed fairly and responsibly. By using this writ to choose a verderer, the people who lived and worked in the forests could have a say in how the forests were managed and protected. The examples provided illustrate how viridario eligendo was used in different legal documents throughout history to establish and maintain a system of forest management.
