Size of shadowiSize of shadow based on a fully grown tree, categorised as low, medium or high: High (320 sqm)

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

Leaf emergenceiTime of leaf emergence, categorised as very early, early, late, or evergreen: Evergreen 1

Growth rateiHow quickly the tree grows during establishment. Categorised as low, moderate or high, with very high used in exceptional cases.: High to very high 49

LongevityiExpected lifespan of the tree: Unknown

Timber is rarely acceptable for sawmills 2
Max YC 26 4, typically between 10 and 25 2

BiomassiCommon biomass products such as fuelwood: Fuelwood 12

Speciality productsiOther speciality and niche products: Oil 12

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 – shallow roots but large 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): Very high
Medium-term (40 years): Very high
Long-term (60 years): Very high

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: Negligible, except for bees and other pollinating insects 4

Other environmental impactsiOther impacts such as water consumption and nutrient leaching: High water consumption 34

Pollinators

Flowering period (pollinator benefit)iTypical flowering months: Jun-Jul 1

High pollen and nectar value for pollinatorsiValue of flowers to pollinators: High 2

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: Highly flammable 6

Disease susceptibilityiSusceptibility of the tree (not tree products) to diseases, e.g. fungal and bacterial disease:
Low
Few reported disease issues but may be susceptible to silver leaf, oedema and honey fungus 6

Invertebrate pest susceptibilityiSusceptibility of the tree (not tree products) to invertebrate pests, e.g. aphids and other insects:
Low
Few, but susceptible to eucalyptus gall wasp 3
May be susceptible to eucalyptus gall wasp and eucalyptus sucker 6

Vertebrate damage susceptibilityiSusceptibility of the tree (not tree products) to vertebrate pests, e.g. squirrels and deer:
Low to moderate
Low sensitivity to browsing 6
Very palatable to browisng mammals, but no more than most natives 5
