SGER: Cerro Grande/Viveash Fire Research Project

新墨西哥州最近发生的Cerro Grande和Viveash野火为研究密集更新努力对两种不同森林类型的早期影响提供了一个独特的机会。今年夏天，超过72万点种子被应用于Cerro Grande烧伤现场，其中大部分是非本土牧草。同样，还向Viveash网站提供了23万磅种子。对文献的回顾表明，在这样的西南部森林生态系统中，还没有进行过评估补种效果的生态学研究，特别是对非本地物种的补种。该项目将在野火后的头两个生长季监测引进的、播种的和火灾后本地紧急物种的建立和分布情况。在这项探索性研究中收集的数据将被用来测试空间显式模型，这些模型预测在播种和未播种的火烧区引进和本地植物物种之间的分布和持续模式。这些模型可用于检验补播的长期有效性，以及引入非天然树种对中等海拔黄皮松和高海拔云杉/冷杉林系统恢复和演替格局的影响。

0104202TierneyThe recent Cerro Grande and Viveash wildfires in New Mexico provide a unique opportunity to study the early effects of intensive regeneration efforts on two distinct forest types. Over 720,000 poinds of seed, most of which was non-native grasses, was applied to the Cerro Grande burn site over this summer. Similarly, 230,000 pounds of seed were also applied to the Viveash site. Review of the literature suggests that ecological studies evaluating the effects of reseeding, particularly with non-native species, have not been conducted in such southwestern forest ecosystems. This project will monitor the establishment and distribution of introduced, seeded and post-fire native emergent species in the first two growing seasons following the wildfires. Data collected in this exploratory study will be used to test spatially explicit models that predict patterns of distribution and persistence among introduced and native plant species in seeded and unseeded burned areas. These models are useful in examining the long-term effectiveness of reseeding and the effects of introducing non-ntaive species on patterns of recovery and succession in mid-elevation Ponderosa pine and high-elevation spruce/fir forest systems.
