| Legend order | Code | Group | Current and Past Types | Period | Description | |
| 00P | 63 | enclosures and farming | ancient field system | prehistoric - roman | Earthworks and cropmarks of complexes of fields which appear to form a coherent system, used only as a previous type. | |
| 01C | 7 | enclosures and farming | assarted enclosure | pre 18th C | Fields created by the enclosure and clearance of woodland or common heath, mostly medieval in origin. | |
| 02C | 3 | enclosures and farming | pre18thC irregular fields | pre 18th C | Irregularly-shaped, small to medium sized fields with boundaries composed mainly of hedges. They are representative of the later medieval/early post-medieval, and possibly earlier, methods of farming in the district. | |
| 03C | 15 | enclosures and farming | pre18thC sinuous fields | pre 18th C | A sinuous form of early enclosures, usually bounded by hedges, which are similar in origin to HLC type Pre 18th century Irregular Fields. | |
| 04C | 53 | enclosures and farming | pre18thC regular fields | pre 18th C | Regularly-shaped, small to medium sized fields with boundaries composed mainly of hedges. Like Pre 18th century Sinuous Fields and Irregular Fields they are medieval or early post-medieval in date but have a greater degree of regularity in their forms, likely to be because they are the result of phases of planned, but undocumented, enclosure. | |
| 05C | 81 | enclosures and farming | enclosed meadows | pre 18th C | Sinuous fields found on low-lying ground in valley bottoms, usually next to the course of a river or stream. These fields were probably originally used for hay cultivation but are mainly now used for grazing. | |
| 06C | 1 | enclosures and farming | parliamentary enclosures | 18th - 19th C | Fields created by formal enclosure by Act of Parliament (in West Berkshire between 1738 and 1858). The fields created by this process are usually regular in shape with straight boundaries and the boundaries are usually hedged and/or fenced. | |
| 07C | 4 | enclosures and farming | post-parliamentary enclosures | 19th C | Fields created in the later 19th century, usually through private enclosure of parkland, woods, commons, downland and some remaining areas of open-field arable. | |
| 08C | 69 | enclosures and farming | 19thC replanned fields | 19th C | Fields created through the wholesale re-organisation of existing agricultural units during the 19th century. | |
| 09C | 5 | enclosures and farming | amalgamated fields | mid 20th C - present | Modern fields formed through the consolidation of existing, historic, enclosures into larger holdings, usually to enable more efficient, mechanised arable agriculture. These enclosures are created by the removal of boundaries between fields and are also often known as prairie fields | |
| 10C | 6 | enclosures and farming | reorganised fields | mid 20th C - present | Modern fields formed through the consolidation of existing, historic, enclosures into more regular holdings, usually to enable more efficient, mechanised arable agriculture. These are different to Amalgamated Fields as they are formed not simply through boundary removal. | |
| 11C | 44 | enclosures and farming | new field | mid 20th C - present | Fields (usually arable) created in the later 20th century through enclosure of land not previously part of the farmed landscape. These fields are usually regular in shape and have straight boundaries. | |
| 12C | 37 | other | restored land | mid 20th C - present | Areas in-filled and re-instated following gravel extraction. Most areas have been restored as fields; however some have been restored to grassland or have been planted with trees. | |
| 13C | 11 | enclosures and farming | paddocks | 20th C - present | Small fields for keeping of horses and ponies, usually created by the sub-division of existing fields. | |

| 17C | 39 | settlement | historic settlement | pre 18th C | All pre-18th century settlement, identified using Rocque’s map of Berkshire (1761). This type is mainly made up of extant medieval settlements and includes those of possible earlier origin. | |
| 18C | 41 | settlement | 18 - 19thC settlement | 18th - 19th C | Settlement dating to the 18th and 19th Centuries. Although not as numerous as Historic Settlements, these also display a wide variety of forms; some are simply expansion of existing settlements whilst others are new foundations relating to changes in agriculture and communications. | |
| 19C | 42 | settlement | interwar settlement | early - mid 20th | Early planned suburbs on the fringes of Newbury, characterised by rows of terraces. | |

| 25C | 22 | woodland | old secondary woodland | prehistoric - present | Woodlands in existence by the 19th Century that are not recorded as ancient. It is thought that most are on land that has, at some point, been used for other purposes. Many of these woodlands date back to the earliest mapping sources and are historic landscape features in their own right. | |
| 25C | 25 | woodland | recent secondary woodland | 20th C - present | Non-ancient woodlands that have developed through woodland regeneration and colonisation since the start of the 20th century | |
| 26C | 21 | woodland | plantation woodland | 19th C - present | Blocks of trees, usually of a single species, planted mostly for forestry. Plantations are usually regular in shape and the larger examples have features such as fire-breaks and access tracks. | |

| 29P | 66 | open land | open field | medieval | Large, usually unhedged, arable fields divided into strips and worked communally. The origin of the open field farming system is contested; however it seems to be broadly medieval in date and to have developed either in the late Saxon or early post-conquest period. | |
| 30C | 61 | open land | meadow | prehistoric - present | A type of common land, riverside meadow originally used for both grazing and for the growth of hay for livestock feed. | |
| 31C | 14 | open land | commons & greens | medieval | Open areas established in/by the medieval period and used for grazing, as a fuel source and for the location of certain industries.

| 63P | 64 | archaeology | lynchets | medieval | Earthwork banks formed by ploughing on a slope, probably medieval in date. Lynchets visible on scarp slopes are thought to indicate an expansion of cultivation onto less suitable land in the medieval period. Found only as a previous type and are recorded where they cover at least one hectare and have an impact on the form of the Current HLC type. | |
