Vegetation Dynamics in Yellowstone’s Northern Range: 1985 to 1999
Open accessAbstract
The Northern Range (NR) of Yellowstone National Park (YNP) is currently a critical area of analysis in the Greater Yellowstone Ecosystem (GYE). The complex dynamic ecosystems in the NR provide outstanding field laboratories for long-term scientific investigations to evaluate management techniques. Grassland and shrubland ecosystems serve as important habitat for a wide variety of animal species in the NR and empirical knowledge of these systems enables managers to better understand the ecological complexities and make informed management decisions. Accurate vegetation maps are useful tools for these land managers, as is the ability to detect changes in vegetation over time. An inexpensive and easily reproducible method for mapping rangelands over the NR was developed utilizing Landsat Enhanced Thematic Mapper Plus (ETM+) satellite imagery. A classification hierarchy of non-forest vegetation was produced with 5 levels, ranging from very broad vegetation types such as woodland, shrubland, or herbaceous vegetation (Level 1) to specific vegetation types such as aspen (Populus tremuloides), tufted hairgrass/sedge (Deschampsia cespitosa/Carex spp.), or big sagebrush/Idaho fescue (Artemisia tridentata/Festuca idahoensis) (Level 5). A 1999 base map of nonforest vegetation in the NR was created using classification tree analysis (CTA) combined with boosting. Overall accuracies of the final maps ranged from 72.30% for Level 5 to 83.65% for Level 1, providing evidence that this method c…

An average increase in woody plant net ecosystem productivity (NEP) of 364-1247 g C·m−2·yr−1 would be required to balance the negative indirect effect of wolves on herbaceous NEP.
“Given that grassland area was recently measured to exceed deciduous forest cover by a factor of 12.13 (Savage and Lawrence 2010), an average increase in woody plant NEP of 364-1247 g C•m -2 •yr -1 would be required to balance the negative indirect effect of wolves on herbaceous NEP.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
