世界木材日基金会和国际木文化学会联合美国落基山研究站,共同制作“西部之火”系列视频。
在过去的几十年中,西部的野火已经成为美国面临的一个日益严重的问题。通过专业研究人员的演讲和小组讨论,我们想向公众展开一场关于野火发生方式和原因的对话,并希望带给人们对野火更多的认识和理解。
在这段视频中,我们邀请了落基山研究站(RMRS)的生态学家Sharon M.Hood博士和科学传播专家Jessica Brewen博士,并荣幸邀请到Steve Ambrose,美国林务局退休林务官员,也是国际木文化学会的志愿者做客主持。演讲和讨论集中在影响森林的两个因素上:野火和树皮甲虫。在演讲环节,Hood博士解释了火灾如何影响树木防御和森林对树皮甲虫的抵抗力;以及我们如何在森林中创造有弹性的环境来抵御甲虫的爆发和其他干扰。
