Book excerpt: Excerpt from Dwarfmistletoe of Ponderosa Pine in the Southwest Since dwarfmistletoe is a natural component of the vegetation in the ponderosa pine type, it is sometimes regarded as a relatively harmless pest. The viewpoint is perhaps tenable as a broad ecological concept but can hardly be considered a paractical one where a particular infected stand must be preserved and.maintained indefinitely for aesthetic or economic purposes. Although dwarfmistletoe does not aten the existence of ponderosa pine as a species, in certain localities it has rendered stands unproductive, unsightly some cases has favored invasion by woodland - type or other species. The fact that some infected stands have given fair to'good yields might also cause one to assume that future yields of the same quantity and quality can be expected. If such were the case, the apparent loss in increment due to dwarfmistletoe might not warrant the cest of Special control.measures. On the other hand, if one considers the insidious aggressiveness of this parasite it is more likely that once it has built up a sizeable population its effect on yield will be pro gressively detrimental in the future and will lead eventually to complete loss.
