Land managers need to understand historical fire regimes (that is, fire frequency and fire severity prior to settlement by Euro-Americans) to be able to define ecologically appropriate goals and objectives for an area. Moreover, managers need spatially explicit knowledge of how historical fire regimes vary across the landscape. Many ecological assessments are enhanced by the characterization of the historical range of variability which helps managers understand: (1) how the driving ecosystem processes vary from site to site; (2) how these processes affected ecosystems in the past; and (3) how these processes might affect the ecosystems of today and the future. Obviously, historical fire regimes are a critical component for characterizing the historical range of variability in the fire-adapted ecosystems of the Northern Rockies. Furthermore, understanding ecosystem departures provides the necessary context for managing sustainable ecosystems. Land managers need to understand how ecosystem processes and functions have changed prior to developing strategies to maintain or restore sustainable systems. In addition, the concept of departure is a key factor for assessing risks to ecosystem components. For example, the departure from historical fire regimes may serve as a useful proxy for the potential of severe fire effects from an ecological perspective. We used a database of nearly all fire history studies in the Northern Rockies to develop modeling rules for predicting historical fire regimes (HFRs). We stratified our tabular fire-history data and our spatial data into ecoregions, potential vegetation types (PVTs), slope classes, and aspect classes to derive rule sets that were then modeled spatially. Expert opinion was substituted for a stratum when empirical data was not available.

The HFR data were prepared to supplement other data necessary to assess integrated risks and opportunities at regional and subregional scales. We derived the HFR theme specifically to estimate an index of the relative change of a disturbance process, and the subsequent patterns of vegetation composition and structure. Historical fire regimes have also proven useful for characterizing wildlife habitats. General Limitations These data were derived using fire history data from 97 different sources. The sampling designs for collecting these data were not intended to sample historical fire regimes across environmental gradients. Consequently, many environmental settings had few to no studies at all. Thus, we had to rely upon interpolation techniques and expert opinion when we lacked data. Data consistency is always a concern when data originates from a variety of sources. Steve Barrett attempted to make the data as consistent as possible when formats varied. These data were designed to characterize broad scale patterns of historical fire regimes for use in regional and subregional assessments. Any decisions based on these data should be supported with field verification, especially at scales finer than 1:100,000. Although the resolution of the HFR theme is 90-meter cell size, the expected accuracy does not warrant their use for analyses of areas smaller than about 10,000 acres (for example, assessments that typically require 1:24,000 data).</PRE></SPAN><BR /> <SCRIPT>fix(original)</SCRIPT> </DIV> </DIV> <DIV STYLE="text-align:center; color:#6495ED">_________________</DIV><BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Status of the data <DIV CLASS="pe2" STYLE="display:none"> Complete<BR /><I>Data update frequency: </I> As needed<BR /></DIV> </DIV> <BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Time period for which the data is relevant <DIV CLASS="pe2" STYLE="display:none"> <DIV><I>Date and time: </I> 10/19/2004</DIV> <DIV> <I>Description: </I> <SPAN CLASS="lt"><PRE ID="original">publication date</PRE></SPAN><BR /> <SCRIPT>fix(original)</SCRIPT> </DIV> </DIV> </DIV> <BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Publication Information <DIV CLASS="pe2" STYLE="display:none"><SPAN CLASS="lt2"> <I>Who created the data: </I>USDA Forest Service, Northern Region<BR /></SPAN> <DIV><I>Date and time: </I> 10/19/2004</DIV> <DIV><I>Publisher and place: </I> USDA Forest Service, Northern Region, Kalispell, MT </DIV> </DIV> </DIV> <DIV STYLE="text-align:center; color:#6495ED">_________________</DIV><BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Data storage and access information <DIV CLASS="pe2" STYLE="display:none"> <I>File name: </I>historic_fire_regime<BR /> <I>Type of data: </I>vector digital data<BR /> <DIV><I>Location of the data: </I></DIV><DIV><LI STYLE="margin-left:0.2in">\\LTHP90808CB\C$\fsfiles\ref\library\gis\clw\geodatabase\fire.mdb</LI></DIV> <I>Data processing environment: </I><SPAN CLASS="lt">Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.3.1.3000</SPAN><BR /> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Accessing the data <DIV CLASS="pe2" STYLE="display:none"> <I>Size of the data: </I>6.795 MB<BR /> <I>Data transfer size: </I>6.795 MB<BR /> <BR /> </DIV> </DIV> <DIV CLASS="ph1" onmouseover="doHilite()" onmouseout="doHilite()" onclick="hideShowGroup(this)">Constraints on accessing and using the data <DIV CLASS="pe2" STYLE="display:none"> <I>Access constraints: </I> <SPAN CLASS="lt">This data set is in the public domain, and the recipient may not assert any proprietary rights thereto nor represent it to anyone as other than a data set produced by the USDA Forest Service, Flathead National Forest<BR /></SPAN><DIV> <I>Use constraints: </I> <SPAN CLASS="lt"><PRE ID="original">This data set is provided "as-is" without warranty of any kind, including, but not limited to, the implied warranties of merchantability and fitness or a particular purpose.
