Other selection factors:
*Most bioretention cells will be situated to receive full sun exposure.
*Most bioretention cells will be situated to receive full sun exposure.
*Facilities with a deeper media bed (greater than 1 m) provide the opportunity for a wider range of plant species (including [[trees]]).

*The inclusion of vegetation with a variety of moisture tolerances ensures that the bioretention cell will adapt to a variety of weather conditions.

Selecting plant material that will be appropriate for a particular site should take into consideration the local context or setting. Some species, especially rare or potentially aggressive species, are not always conducive to the type of site or objective of the project, especially in areas near or next to natural communities. For example, a green roof that is isolated from all natural areas may be ideal for regionally rare species that are specially adapted to conditions of high exposure and shallow soils. Among the questions that should be asked are:

For example, a green roof that is isolated from all natural areas may be ideal for regionally rare species that are specially adapted to conditions of high exposure and shallow soils. Among the questions that should be asked are:
*Is this LID site located within, adjacent or close to a natural area? Or, is this LID site location isolated (i.e. beyond 120 m of natural feature) from the natural environment?

*What is the composition of the nearby natural area?
