The Buffalo Creek water, <br />shed will not heal for decades. <br /> <br />Dense forests are a double whammy <br />for water users, Dense forests <br />reduce water yield. And, w <br />dense forests bum, they bum so hot <br />that soils are damaged. Vegetation <br />recovery then takes much longer than <br />if fires were not so heavily fueled. <br />Flooding associated with super-hot <br />fires is very expensive, hannful to <br />water quality and can be deadly. <br /> <br /> <br />By looking at the results of another <br />disastrous forest fire, one can get a <br />picture of what the forest may have <br />looked like before Colorado's settle- <br />ment period, TIle Black TIger Gulch <br />fire roared out of Boulder Canyon and <br />"chimneyed" up the gulch consuming <br />everything in its path. including <br />homes. The heat here was similar to <br />Buffalo Creek. Yet by nightfall that <br />first day, the fire had laid down and <br />was creeping slowly and diagonally <br />across some hillsides. The cooler <br />night-time fire only killed about half or <br />more of the trees in its path. One can <br />see parts of these "fire-thinned" <br />stands of trees by looking up from <br />Boulder Canyon. <br /> <br />20,000 <br /> <br />.., 18,000 <br />c <br />~ 16,000 <br />fIl <br />.. <br />~ 14,000 <br />- <br />r! 12,000 <br />" <br />:s 10.000 <br />= <br />U <br /> 8,000 <br /> 6,000 10 <br /> <br />delayed vegetation recovery that follows super-hot <br />wildfires like Buffalo Creek. <br /> <br />Forestry is only possible, however, with an informed <br />citizenry possessing understanding about various affects <br />on forests caused by human endeavors and natural <br />processes.

Change in Magnitude of Poudre River Floods <br /> <br />Should society find it acceptable, foresters can restore <br />forest conditions much like the cool, night-time fire did at <br />Black TIger Gulch. By design, we could have safer <br />forests. Tree-dominated landscapes would give way to <br />greater plant and animal diversity. Crown densities could <br />be restored to something in between the barren and flood, <br />prone hills of yesteryear, and the overcrowded fire and <br />flood disaster,prone hills of today. <br /> <br />Forestry would entail as much of a landscaping art as <br />science-based management. The temporary and neces- <br />sary disturbances caused by thinning, harvesting and <br />prescribed fire would heal in a matter of years.

The costs will hun. And citizens will demand <br />appropriate forestry action. On the other hand, some <br />research-based knowledge is available now, With citizen <br />support, there can be forestry action to restore forest <br />conditions favorable for water flows. <br /> <br />- - <br /> <br />--.". <br />
