我们目前的数据从两个老的增长站洛洛国家森林代表的栖息地，对比与落叶松的立场。其中一个立场是一个混合物的松树和落叶松在一个陡峭的高地斜坡，另一个是落叶松为主的易霜冻的谷底明显在冷的限制黄松。我们还合成和比较年龄组的数据，断面积（BA），和林分密度指数（SDI）的整个范围内的老增长的立场，我们已经抽样代表历史频繁的火灾类型在蒙大拿州西部。
We present data from two old growth stands on Lolo National Forest representing habitats that contrast with larch stand. One of the stands is a mixture of pine and larch on a steep upland slope and the other is larch dominated in a frost-prone valley bottom evidently at the cold limits of ponderosa pine. We also synthesize and compare age-class data, basal areas (BA), and Stand Density Indexes (SDI) for the entire range of old growth stands that we have sampled to represent the historical frequent fire types in western Montana.
