Visually Determined Soil Disturbance Classes Used as Indices of Forest Harvesting Disturbance

Visually Determined Soil Disturbance Classes Used as Indices of Forest Harvesting Disturbance

Visual estimates of soil and site disturbances are used by foresters, soil scientists, logging supervisors . and machinery operators to minimize harvest dis turbances to forest s i tes , to evaIuate compliance with forestry Best Management Pract ices (BMPs), and to determine the need for ameliorative pract ices such as tnechanical s i te preparat ion. Al though visual est imates are commonly us...

Assessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.

Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...

Bird Composition as an Ecological Indicator of Forest Disturbance Levels

Ecological indicators are needed to evaluate natural biodiversity and to estimate environmental change. I used bird community composition as an environmental indicator to evaluate forest disturbance (at the community level) in areas of Western Mexico. Surveyed bird and vegetation composition data at 79 sites within regions of the Sierra Madre del Sur and Transvolcanic Belt Provinces of Central ...
