grassland : an ecological community in which the characteristic plants are grasses — Webster
Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth’s surface. — Wikipedia

Q&A: Landscape ecologist says California...
on September 30, 2020 at 3:04 pm
For the past several weeks, dozens of wildfires have scorched a destructive path across western forests and plains, threatening homes and habitat—as of this week, more than 5 million acres in California, Oregon and Washington have been destroyed by some of the largest wildfires in the region's history. Monica Turner, a landscape ecologist in the Department of Integrative Biology, spent several decades studying the ecosystems of Yellowstone National Park after wildfires ravaged the park in […]
Biodiversity and plant decomposition should be...

The afterlife of plant matter plays a significant role in ecosystems, as a key processor and provider of key nutrients. The rate of decomposition for leaf litter, among other plant matter, heavily influences the health of animals and plants, and this rate is expected to significantly increase as Earth continues to warm. There is another factor that could hold impact these ecosystems even more than climate change: biodiversity.

Amazonia is closer to a catastrophic ecological tipping point than any time in the last 100,000 years, and human activity is the cause.
Just add water: Biodiversity resurgence in...

Throughout the late 19th century, rivers across the southwestern United States were parceled out, and flows were diverted through irrigation canals and trapped behind dams. Growing populations put new demands on groundwater sources. Coupled with changing climate conditions, water tables sank and perennial streams began to run dry.
Forest margins may be more resilient to climate...

A warming climate and more frequent wildfires do not necessarily mean the western United States will see the forest loss that many scientists expect. Dry forest margins may be more resilient to climate change than previously thought if managed appropriately, according to Penn State researchers.
