Pertanyaan
Raging fires such as Le De Conchita may do, among others, the following: leaving few seed sources stripping soils of nutrients and increasing the likelihood of landslides. In their wake,vegetation of any.kind can struggle to ping root. By looking at tree rings, Park Williams of the Los.Alamos National Laboratory and his colleagues are able to access how droughts stress south western forests. They forecast that if temperatures rise as projected by climate models, trees will face worse drought stress in the first half of the twenty-first-century than they have experienced for 1,000 years, probably driving a transformation of the ecosystem. And when trees and shrubs do regrow, the region's warming temperatures and more frequent dry.spells are likely to favour heat-and-drought -tolerant species, mostly bringing about such ecosystem transformation. Some of the Jemez s areas have seemingly begun to experience the transformation. In 1996 the Zone Fire burned almost7,000 hectares in the mountains, leaving patches of dead trees that at the time seemed surprisingly large . When the Le De Conchita fire roared through some of the same areas last summer, the oaks burned hot and fast,killing almost all the conifers thathad survived the Zone Fire. But subsequently swathes of shrubby vegetation sprouted in the burned patches ,surrounding the small islands of surviving ponderosa pine and other conifers. Since the shrubs are better adapted to warmer,drier conditions than the trees, they will predictably regrow in even larger patches. Eventually , they could dominate the landscape and establish a pattern of intense and frequent fires that is currently more common in coastal California and other Mediterranean-style eccsystems. 125.What are the fires mentioned in the text?
