description       Grids of Annual Severity of MPB infestation for 1999 to 2011.  Based on the Provincial Aerial Overview of Forest Health (http://www.for.gov.bc.ca/hfp/health/overview/overview.htm) and developed for the BCMPB projection model (version 9).

projection        BC Albers Equal Area.  Please see the following Web page for parameters, http://www.ilmb.gov.bc.ca/risc/pubs/other/mappro/map.htm.
warnings          Please consult the "Infestation Projection" report, available at http://www.for.gov.bc.ca/hre/bcmpb, to obtain further information regarding the current infestation projection. 
                  We are reasonably confident in the model's observed and projected infestation estimates at the PROVINCIAL and DISTRICT SCALES, but the specific progression of the outbreak at finer scales, such as a "watershed" or a "pixel", is most likely wrong because theses finer scales exceed the resolution of the model.
                  The projection provided is one instance of the output from a stochastic model.  It is a projection of what might happen rather than a prediction of what will happen.  Please use and interpret the data accordingly.
