| Year of collection of the field data entered: | 2021 |
| Year of the most recent visit: | 2023 |
| Remarks on specific soil characteristics: | Lowland moor: diverse matrix of brown earth, podzol, rock, bog and peaty pockets |
| Remarks on other specific characteristics of the unit: | 20 ha open, diverse native woodland / wood pasture adjacent to recently cleared 70 ha Sitka plantation, managed by light cattle grazing as a complex of native woodland, bog and wood pasture. Oldest wild apples are probably 200 years old; young ones germinate each year. |

| National population unit number if existing: | |
| Year of establishment of the GCU for the species: | 2023 |
| Year of the most recent visit: | 2021 |
| Status of the target tree population regarding the EUFORGEN common action plans.: | Included |
| Category of the population: | In situ |
| Origin of the material: | Autochtonous |
| Predominant silvicultural system: | No silviculture |
| Level of management allowed to favour the target species: | Minimum intervention allowed |
| Main reason for carrying out gene conservation for this species: | To conserve rare or endangered tree species with populations consisting of a low number of remaining individuals |
| Total number of reproducing trees per unit: | 50 - 499 |
| Sex ratio, if appropriate: | |
| Status of long-term viable regeneration : | Continuous |
| Distribution of the reproducing trees in the unit (multiple choice): | Scattered |
| Estimated share of the total area within the unit in which the species is occurring (%): | 1 |
| Remarks on the population: | Cows eat apples in autumn, seed is spread through cowpats and deposited throughout free-range area. Seed from most remote and pure wild apple trees are given to local seed nurseries. |
