Tiger bush consists of stripes of bushes on arid slopes in countries such as [[Niger]] where plant growth is limited by rainfall.

When trees fall, the trees that they had sheltered become exposed and are in turn more likely to be damaged, so gaps tend to expand downwind.

虎皮纹灌木和冷杉波纹等植被斑图形成的原因不同。在尼日尔等干旱国家，植物生长受到降雨的限制，虎皮纹灌木由干旱斜坡上的带状灌木组成。每一条大致水平的植被带都可以从紧靠其上方的裸露地带吸收雨水。相比之下，在受到大风摧残后的植被再生过程中，山坡上的森林会出现冷杉波纹。当较外层树木倒下时，曾经受到它们庇护的内层树木会暴露在外，进而这部分植被更容易受到破坏。因此，树林空隙往往向背风面扩大。同时在迎风坡，幼树在生长过程中则受到存活下来的高大树木自然形成的风影区保护。因此在平坦的地形中，植被除了条带状之外，还出现了其他的斑图形态—例如六边形缝隙斑图和六边形点状斑图。在这种情况下，植被斑图是在当地植被生长和朝向生长位置的水分输送之间的正反馈回路驱动下形成的。
