Measuring grassland response to management using optical remote sensing
… optical RS for evaluating grassland conditions (dead material estimation and the issue of mixed pixel for green vegetation extraction), to monitor the lag impact of long-term conservation actions, and to quantify and separate the effects of management and climate conditions as well as their …

Wildland fuel loading estimates along a gradient of forest cover types and landscape factors in Harpers Ferry National Historic Park, West Virginia and Rock Creek Park, Virginia, USA
… and potential fire effects. Standing and dead trees, downed woody material, litter (Oi Horizon), and duff (Oe+Oa Horizons) contribute to fuel loading and fire risk. They also play a critical role in overall ecosystem health. Downed woody material contributes to carbon storage and nutrient …

Overstory structure and detrital dynamics of ponderosa pine forests: insights into fire behavior and its carbon consequences
… the long-term dynamics of detrital pools (dead wood, litter, duff). Woody detritus accumulated quickly after a fire, as dead material fell. This peak then decomposed before pool size increased again as new material fell. Litter accumulated monotonically, and was most strongly related to …

Investigation into the plant ecology of the Karstland area in Namibia : with particular reference to the proposed large-scale abstraction of groundwater
… of the parameters such as the quantity of dead material, and the number of standing dead trees, reflected a general decline in vitality over the two year period. In view of the poor rainfall conditions, this decline was interpreted as that which can be expected under natural adverse …

Evaluation of perennial ryegrass cultivars for dairy production under different pasture management
… tetraploid cultivars, Base and Bealey, had less dead material proportion (16.0% vs. 18.0% at the pre-heading vegetative stage; 22.0% vs. 27.0% at post-flowering vegetative stage) and greater lamina proportion (51.7% vs. 45.1% at the pre-heading vegetative stage; 55.0% vs. 50.7% at post-flowering …
