The Tree Library is your toolbox to define the new 3D plant geometries introduced in ENVI-met. It supports you with data management, plant generation and modification and directly integrates into the new ENVI-met database system. The parameters for editing trees are described below.

The LAD describes the amount of leaf surface area in a given volume of air, usually measured in square meters of leaf area per cubic meter of space (m²/m³)===. Higher LAD values indicate denser foliage, which influences shading, wind flow, and evaporation in a microclimate. * Note for Simple Plants: Regardless of height, each simple plant is made up of 10 sections in which the LAD can be changed. This ensures that you can define the plant as close as possible.

The LAI represents the total leaf surface area per unit of ground area (m² of leaves per m² of ground)===. It indicates how much vegetation covers a surface, affecting shading, evapotranspiration, and overall microclimate conditions.

Height of the rotation plant

Width of the rotation plant

Defines how deep the roots reach into the soil profile

Width of the root zone

A tag that refers to the photosynthetic pathway a plant uses to absorb and process carbon dioxide. The fixation type is either C3 or C4.

A tag that defined is the plant is decidous or coniferous

Defines the leafs' Albedo

Defines the fraction of incoming shortwave radiation being transmitted through the leafs

Defines how much absorbed radiation the leafs emit compared to a black body

Defines the inherent ability of plants to produce and release isoprene. Isoprene production is increased under moderate hat stress as a protective response to stabilize cell membranes.

It is the tree's material property that describes its resistance to deformation under a tensile or compressive force - given in GPa.

Describes the maximum stress the tree can withstand in bending before breaking or rupturing.

The RAD describes the amount of root surface area in a given volume of soil, usually measured in square meters of root area per cubic meter of space (m²/m³)===.

Defines how far the nodes in an L-Tree are placed apart. With decreasing distance, more leafs will be created.
