Tropical forests recover after deforestation

By | Forestry, News

Tropical forests are disappearing at an alarming rate through deforestation, but they also have the potential to regrow naturally on abandoned lands. This has been shown by an international study led by scientists from Wageningen University. How a forest recovers, depends on the amount of rainfall, the age of the forest, and the functional characteristics of the tree species.

The challenge of forest restoration: Where to obtain tens of billions of quality seeds

By | Forestry, News

With commitments to restore more than 47.5 million hectares of degraded land and forests by 2030, the Philippines, Indonesia, Malaysia and India hope to become exemplar land custodians. While commitments ending deforestation are critical to obtaining that image—Indonesia is one of the world’s poster children for forest loss—even a full halt to natural landscape destruction is only part of the battle to fight climate change and restore myriad ecosystem services, which the United Nations Food and Agriculture Organization simply states, “make human life possible.”

A preliminary framework for better urban agroforestry

By | Forestry, News, Research

Today’s cities don’t have walls for protection like ancient ones, but they are separate from less urban and rural land. Most goods that city-dwellers purchase are brought in from rural farms and manufacturers. There is an active community of urban gardeners and landscape architects who are trying to bring more of the “country” back into the city. And for good reason. Urban landscapes combining trees and crops – urban agroforestry – can offer ecological, cultural, economic benefits and more.

Mediterranean old-growth forests exhibit resistance to climate warming

By | Forestry, News, Plant Science

European old-growth forests are estimated to occupy only 0.7% of the total forested area; they are of prime ecological value, representing small vestiges of how Europe’s past primeval forest may have looked. In addition, old-growth forests provide various and important ecosystem services, such as biodiversity maintenance, long-term carbon storage, and landscape uniqueness. Therefore, old-growth forests represent valuable natural laboratories for evaluating how trees of different dimensions and ages respond to global change drivers, including climate warming and land-use changes. Although there is increasing attention on these ecosystems, knowledge of the long-term impacts of climate change in the Mediterranean environment is still limited. A recent study found that in Mediterranean mountainous area old-growth forests show remarkable resistance to climate warning.

DNA duplication linked to the origin and evolution of pine trees and their relatives

By | Forestry, News, Plant Science

A new study shows that duplication events have been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads. The research indicates that a genome duplication in the ancestor of modern gymnosperms might have directly contributed to the origin of the group over 350 million years ago.
