===== Deciduous and evergreen vegetation =====
There are different tree effects for different types of vegetation in a texture sheet. Flightgear supports an autumn effect for types of vegetation with leaves that gradually become yellow or red and drop off in autumn - {{Wikipedia|Deciduous|deciduous}} vegetation. Vegetation whose leaves do not fall off is called {{Wikipedia|Evergreen|evergreen}} vegetation. Most tropical vegetation, and vegetation that originates in warmer climates, are evergreens. There is some deciduous vegetation in warmer climates that drop leaves in the dry season. The vast majority of {{Wikipedia|Conifers|conifers}} are also deciduous although there are some confiers whose leaves fall off and change colour. Texture sheets can have a mixture of deciduous and evergreen vegetation. As of March 2021,  deciduous vegetation is placed first in each row, followed by evergreen vegetation.
