Max. canopy widthiLikely maximum horizontal width of the canopy, in metres:
Globular, bushy crown 1
Irregular spreading 3
2.5-4m wide 2

Size of shadowiSize of shadow based on a fully grown tree, categorised as low, medium or high: Low (9 sqm)

Canopy densityiShading intensity of the canopy when in full leaf. Categorised from open to dense.: Dense 1

Leaf emergenceiTime of leaf emergence, categorised as very early, early, late, or evergreen: Early (Apr to Nov 1)

Growth rateiHow quickly the tree grows during establishment. Categorised as low, moderate or high, with very high used in exceptional cases.: Moderate 9, but depends on cultivar 8

LongevityiExpected lifespan of the tree: 50 years 20

Ecology & Utility

Nutrient and organic matter accumulationiRough estimate of soil-improving properties, with larger and deeper-rooting trees predicted to have higher value. Categorised as low, moderate or high.: Moderate – deep roots and low canopy area

Nitrogen fixationiNitrogen-fixing properties, categorised as yes or no: No

High carbon sequestrationiAll trees sequester carbon, but faster-growing, larger trees generally have higher sequestration potential.:
Short-term (20 years): Relatively low
Medium-term (40 years): Very low
Long-term (60 years): Very low

Native status in the UKiCategorised as native, long-established, or recent introduction.: Recent introduction (neophyte) – survivor 1

High wildlife valueiMost trees are likely to be of some value to wildlife, but some trees are of generally higher value to various wildlife groups: Likely moderate based on neophyte status balanced against pollinator value

Pollinators

Flowering period (pollinator benefit)iTypical flowering months: Apr-May 1

High pollen and nectar value for pollinatorsiValue of flowers to pollinators: Likely moderate to high

Susceptibility & Risks

Risk of toxicity to livestockiReported potential toxicity to livestock, categorised as yes or no. Toxicity is complex and often context-specific.: None known

Risks to farming operationsiOther risks such as suckering roots, very large tree size, secondary host for aphids, and flammability: Suckers are common 11

Disease susceptibilityiSusceptibility of the tree (not tree products) to diseases, e.g. fungal and bacterial disease:
Low to moderate
Particularly affected by quince leaf blight and brown rot, but also honey fungus, replant disease, powdery mildew, and silver leaf 213
Generally disease free except for leaf blight 14

Invertebrate pest susceptibilityiSusceptibility of the tree (not tree products) to invertebrate pests, e.g. aphids and other insects:
Low
Occasionally affected by codling moth and winter moth 13
May be susceptible to catepillars and aphids 2
Generally pest free 14

Vertebrate damage susceptibilityiSusceptibility of the tree (not tree products) to vertebrate pests, e.g. squirrels and deer: Likely low
