Timber harvest and forest treatments effect hydrology in various ways. Check out this paper that delves into this relationship and various methods researchers use to evaluate long-term impacts of these activities.

Evaluating the effects of timber harvest on hydrologically sensitive areas and hydrologic response

  • Timber harvest effects vary with changing topography, climate, and harvest regimes.
  • Thinning on low runoff probability areas cut peak flow up to 40% from clearcutting.
  • Logging in areas of high runoff probability led to higher peak flows.
  • Harvest in low runoff probability areas caused large peak flow in snowmelt events.
  • Timber harvest planning can be improved based on hydrological response analysis.
