In contrast to the widely held view that forest management should emphasize providing water for downstream uses, we argue that maintaining forest health in the context of a changing climate may require focusing on the forests themselves and on strategies to reduce their vulnerability to increasing water stress. Hydrologic modeling reveals that specific management actions could reduce tree mortality due to drought stress.
Planting trees only works if the restored forests stand for more than 10 or 20 years
Tropical forests globally are being lost at a rate of 61, square miles a year. And despite conservation efforts, the global rate of loss is accelerating. In it reached a year high PDF , with , square miles cleared. At the same time, many countries are pledging to restore large swaths of forests. In the New York Declaration on Forests increased this goal to 1. Ecological restoration is a process of helping damaged ecosystems recover.
A forest is a large area dominated by trees. Forests are the dominant terrestrial ecosystem of Earth, and are distributed around the globe. Net primary production is estimated at Forests at different latitudes and elevations form distinctly different ecozones : boreal forests around the poles , tropical forests around the Equator , and temperate forests at the middle latitudes. Higher elevation areas tend to support forests similar to those at higher latitudes, and amount of precipitation also affects forest composition. Human society and forests influence each other in both positive and negative ways. Forests can also affect people's health.
Forest Conservation Program
The Forest Conservation Law aims to save, maintain and plant forested areas for the benefit of county residents and future generations. Trees and forests filter groundwater, slow stormwater runoff, help alleviate flooding and supply wildlife habitat. Trees cleanse the air, offset the heat generated by development and reduce energy needs. And in a less tangible sense, trees improve quality of life in a community by providing recreation and visual appeal. Since , the Planning Department has approved development applications that have permanently protected some 9, acres of existing forest and 2, acres of newly planted forests.
