Tree height

Taller trees intercept more light and their stature facilitates seed dispersal, which trade-offs against the increase in construction and maintenance costs and risk of breakage.

110,111

Rooting depth

Deeper roots enhance water uptake and tree stability, but also increases maintenance cost.

112,113

Specific leaf area (SLA)

A high SLA results in a short leaf lifespan and high carbon gain, and a low SLA is related to a long leaf lifespan and efficient nutrient conservation.

Stem conduit diameter

A wider stem conduit diameter results in more efficient water transportation, which increases plant productivity but also the risk of embolism.

114,115

Crown diameter

A larger crown diameter is related to a higher photosynthetic capacity, as more leaves are sun-exposed, but also increases the risk of branch damage.

116

Wood density

A higher wood density relates to better mechanical support, water transport and storage capacity of woody tissues, and is associated with slower growing species due to the energy investment.

105

Bark thickness

A thicker bark is related to water storage and fire protection, but results in a stiffer stem, which makes it more prone to stem breakage.

117,118

Leaf nitrogen

Leaf nitrogen reflects a trade-off between the benefits of a high photosynthetic potential with high nitrogen and the costs of acquiring nitrogen and suffering herbivory.

119,120

Leaf N/P ratio

A low N/P ratio indicate a high biomass production and a quick return on investments of carbon and nutrients, while a high N/P ratio promotes stress tolerance.

70,121

Seed mass

A higher seed mass results in a higher chance of seedling survival and at the same time a lower number of seeds produced and therefore a lower colonisation ability.
