Forests face an increasing number of threats, which are expected to increase in frequency and intensity in the future. Recent calls have pointed out the need for holistic approaches when developing forest management policies, which requires a broad understanding of how forest owners perceive the uncertainties and risks that may threaten their forests. In this paper, we study a set of sixteen concerns in the United States National Woodland Owner Survey (NWOS). Our set of concerns span an array of types and causes—natural and anthropogenic—that capture multiple aspects of forest ownership....

Marchalina hellenica (Gennadius) (Hemiptera: Marchalinidae), endemic to Greece and Türkiye, infests various pine species in both countries. Apart from its native range, this species has been recorded infesting pine trees in Italy [Campania (island of Ischia) and Marche regions], Croatia, and recently in Australia. While not a severe pest in its native habitat, M. hellenica has been found to negatively impact pines in the invaded regions.Neoleucopis kartliana (Tanasijtshuk) (Diptera: Chamaemyiidae), a key natural enemy of M. hellenica in its native range, was introduced from Greece to...

Catastrophic wildfire has escalated across the globe in recent decades with devastating consequences for human communities and native ecosystems. Global change processes, including climate warming and land use practices, are altering fuels, fire risk, and ecosystem recovery. Managing ecosystems to reduce fire risk and prevent conversion to undesirable alternative states requires knowledge of the ecological conditions of ecosystems, trajectories of change, and drivers of those changes. We developed an approach for evaluating ongoing changes in climate and vegetation and using that informatio...

The U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program provides this resource update yearly as an overview of forest resources in Delaware. These estimates are derived from field data collected across a systematic network of fixed-radius forest monitoring plots located on both public and private land. New updates are provided annually as a subset of plots within the State are remeasured. Each year, field crews visit and measure a subset of all FIA plots across the entire State (the size of the subset varies by State and year). Combining all...
