Apart from disrupting the river ecologies, excessive jeep traffic can cause even more damage in the forests, says Li Ling-ling, an associate professor of zoology at National Taiwan University. The damage is greatest when jeepers want to show their courage and strut their automotive stuff by heading off road and onto the river beds.
除了在溪床操車會破壞河川生態環境，台大動物系副教授李玲玲也指出，如果吉普車造訪山林的次數太頻繁，一次去的車輛數目又很多，破壞就會更加嚴重。如果車友為表示「神勇」，炫耀車子性能，而故意開離路面，開到溪床上玩車，對地質和生態的破壞更是直接。
