Ostrom identified eight design principles for successful common resource management. These included the adoption of clearly defined boundaries and use rights, the adoption of collective choice arrangements in which all affected individuals can participate, the monitoring of resource use and the application of graduated sanctions for breach of resource allocation rules. There is now a substantial literature critiquing, refining and developing the design principles. See e.g. T. Dietz, E. Ostrom and P.C.

Page and Brower refer to the “paradox” of public property in land, “a resource critical to our well-being and propriety, yet … sorely under-theorised in the common law … an ill-defined topic into which few legal scholars wade” (ibid., at p. 297).

²⁵ See Singer, Entitlement, pp. 2, 3.

²⁶ But note the spectrum of ownership models for “public” property identified by Page and Brouwer, “The Four Dimensions” – including the “state as owner” model, the “many owners” model and the “unorganised public” as owner (pp. 297ff.).

³⁶ This is the case for “access land” mapped by public bodies for public recreational access under the Countryside and Rights Act 2000, for example: see note 38 below.

⁴⁵ Although important, commons and village greens are not the only land over which public access may be secured. Land can be voluntarily dedicated by the landowner for open air recreation under an access agreement if it is in “open country”, i.e. “any area appearing … to consist wholly or predominantly of mountain, moor, heath etc. or foreshore”: National Parks and Access to the Countryside Act 1949, s. 60, Sch. 2. Or it may be “dedicated access land” that the landowner dedicates under the Countryside & Rights of Way Act 2000, s. 16. Coastal access rights can also be dedicated under the Marine & Coastal Access Act 2009, Part 9.

⁴⁹ For the classification of the various common rights recognised in English law, see Cousins, E., Gadsden on Commons and Greens, 2nd ed. (London 2012)Google Scholar, paras. 2-34 to 2-65. Many established rights are difficult to place within one or more of the recognised categories described here.

⁵⁰ There are several subcategories of the profit of estover; “house bote” (the right to take timber for repairing houses or as fuel); “plough bote” (to take timber for making or repairing agricultural implements); and “hay bote” (to take timber shrubs or brush to make or repair hedges and fences). See Cousins, Gadsden, para. 2-38.

Electoral ward boundaries had changed during this period, but it was held on the facts that in substance the “locality” was unchanged. Also R.

⁹⁰ To take just one example, the site notification for the Ingleborough SSSI, a large upland protected area in the Yorkshire Dales, sets out 28 OLDSIs, including a prohibition of cultivation, of any change in livestock numbers or livestock management practices, or the application of pesticides or fertilisers to the land: see <https://designatedsites.naturalengland.org.uk/PDFsForWeb/Consent/1001537.pdf>. The list of prohibited operations in most other notified SSSIs is similar in extent, although the operations listed will depend upon the type of land management practised such as whether arable farming, livestock farming, or other operational use is practised (quarrying for example).

⁹¹ This is an example of what Scotford and Walsh have described as the contextualisation and reconstitution of property rights by an administrative regime regulating land use: “the decision-making process surrounding SSSIs involves the determination of land-use rights through administration, which takes account of a variety of interests and overriding legislative considerations and results in a democratic reshaping of property rights”: Scotford and Walsh, “The Symbiosis”, pp. 1027, 1038. For the purposes of the argument pursued here, the key point is that it is only private or common property interests that are reconstituted in this way.

⁹² For example, as in R. v Secretary of State for the Environment ex parte Royal Society for the Protection of Birds [1997] Q.B. 206; [1996] ECR 1-3805.

⁹³ That is, by the statutory conservation body serving a list of OLDSIs on the owner or occupier of the land in question.

A small number were concluded with former owners gifting land to the trust.
