Excerpt from Number of Plots Required for Measuring Productivity on Mountain Grasslands in Montana The purpose of this Research Note is to show the relationship between sample size (number of plots) and precision of measuring production on 12 mountain grassland and shrubland habitat types2 common to western Montana. This information should help the range manager obtain a more realistic view of the validity of his production determinations on these and similar habitat-types, i. Information presented in table 1 was developed from data obtained during a study to determine forage productivity and variability on important habitat types. Ten of the 12 habitat types are represented by three stands selected to span the range in productivity potential for the respective habitat type; the remaining two habitat types are represented by only two stands in each. A sampling technique combining estimation (40 plots) and clipping (10 plots) was used to determine production. The 10 clipped - ft2 circular plots were randomly distributed within each stand. These clipped plots provided an estimate of the coefficient of variation (cv) by vegetation classes and species in each stand. The CV in turn forms the basis for determining the number of plots required to achieve given levels of sampling precision. The formula used to compute the number of plots (n) needed for the specified levels of sampling accuracy (freese 1967) shown in table 1 is.

A classification system based upon potential natural vegetation is presented for the grasslands and shrublands of the mountainous western third of Montana. The classification was developed by analyzing data from 580 stands. Twenty-nine habitat types in 13 climax series are defined and a diagnostic key provided for field identification. Environment, vegetative composition, forage production, changes with grazing, and range management practices are described for each habitat type.

Timber harvesting has a pronounced effect on the soil microflora by wood removal and changing properties. This paper gives a perspective on soil biology-harvesting relationships with emphasis on the northern Rocky Mountain region. Of special significance to forest management operations are the effects of soil micro-organisms on: the availability of soil nutrients, particularly nitrogen; the decay of woody plant material; and tree disease incidence. At present, no widespread detrimental impact on site quality in the northern Rocky Mountain region can be directly attributed to harvesting effects on the soil microflora.
