An intact forest landscape (IFL) is a seamless mosaic of forest and naturally treeless ecosystems with no remotely detected signs of human activity and a minimum area of 500 km2. IFLs are critical for stabilizing terrestrial carbon storage, harboring biodiversity, regulating hydrological regimes, and providing other ecosystem functions. Although the remaining IFLs comprise only 20% of tropical ...

The question of incorporating road maps into U.S. national assessments of forest fragmentation has been a contentious issue, but there has not been a comparative national analysis to inform the debate. Using data and indices from previous national assessments, we compared fragmentation as calculated from high-resolution land-cover maps alone (Method 1) and after superimposing detailed road maps...

Over the past decade, widespread disturbance has brought a large amount of narrow-linear and small-area disturbance features (e.g., ATV trails, seismic lines, pipelines/powerlines, well sites, forest roads and cut blocks) to forest areas in the Foothills Region of Alberta, Canada. This issue has prompted research into finding appropriate data and methods for mapping these narrow-linear and smal...

We performed bimonthly mosquito larval collections during 1 year, in an agricultural settlement in the Brazilian Amazon, as well as an analysis of malaria incidence in neighboring houses. Water collections located at forest fringes were more commonly positive for Anopheles darlingi larvae and Kulldorff spatial analysis pinpointed significant larval clusters at sites directly beneath forest frin...

Nacrtak Opening-up of forests enables the application of rational forestry, which means more productivity and suitability for sustainable use. Therefore, forest roads are one of the most important tools needed. This study investigates tree damage caused by excavated materials during forest road construction in a karst region. Bending, crushing andwoundingwere defined as tree damage because of e...

Despite a marked increase in the focus toward biodiversity conservation in fragmented landscapes, studies that confirm species breeding success are scarce and limited. In this paper, we asked whether local (area of forest patches) and landscape (amount of suitable habitat surrounding of focal patches) factors affect the breeding success of raccoon dogs (Nyctereutes procyonoides) in Tokyo, Centr...

Using recent land cover maps, we used matching techniques to analyze forest cover and assess effectiveness in avoiding deforestation in three main land tenure regimes in Panama, namely protected areas, indigenous territories and non-protected areas. We found that the tenure status of protected areas and indigenous territories (including comarcas and claimed lands) explains a higher rate of succ...

The impacts of forest fragmentation on both reproductive biology and genetic diversity of native plant species is hardly understood, despite some studies have analyzed this current worldwide problem. Since this constitutes one of the main threats to seasonal semi-deciduous forests in Southeastern Brazil, we investigated the reproductive success and the genetic diversity of a distylous, understo...

Timber transportation is one of the most expensive activities in forest operations. Traditionally, the goal of forest transportation planning has been to find the combination of road development and harvest equipment placement that minimizes total harvesting and transportation costs. However, modern transportation problems are not driven only by economics of timber management, but also by multi...
