GRAUMLICH, L.J. and HESSL, A.E. This dissertation research will examine the effects of fire, climate variation, intensity of ungulate browsing and management policy (emphasizing fire and wildlife management) on aspen regeneration over the last two hundred years in northwest Wyoming. Forest age structure will be estimated from tree cores collected in a sample stratified according to fire history and elk-browsing pressure. The inclusion of stands that have been similarly affected by climatic fluctuations, but with distinct management histories, will help the PIs to disentangle the influence of these various factors-something previous studies have not done successfully. The research has implications for understanding ecological dynamics as influenced by resource management practices.

Graumlich，L.J。和Hessl，A.E。本论文研究将研究火灾，气候变化，不受调节的浏览和管理政策的强度（强调火灾和野生动植物管理）对过去两百年来在西北怀俄明州的阿斯彭再生的影响。 森林年龄结构将从根据火史历史和麋鹿浏览压力分层的样品中收集的树芯估算。包含受气候波动类似的立场，但有了不同的管理历史，将有助于PIS解散这些各种因素的影响，这是先前研究的影响并未成功完成。 这项研究对理解受资源管理实践影响的生态动态具有影响。
