Evaluation Crown Height Model Extracted from the UAV in Individual Tree Detection Sisangan Forest Park

Mobile Guiding System for Parks based on highly precision electronic map is of many researchers' concern, but commercial software cannot perform GPS positioning on custom-made maps for parks, and is not accurate enough to satisfy the requirements for drawing high precision electronic maps. This study uses trajectories measured by My Tracks software and a map edited in JOSM software to implement...

With 62 % of its total area covered in forest, Styria is the most densely forested province Austria. Accordingly, forests, more than any other habitat, characterise landscape Styrian Eisenwurzen Nature and Geopark. The forest areas nature park are managed by a combination private owners Provincial Forests, Austrian Federal Forests City Vienna. near-natural forests particular characterised speci...

Forest succession on degraded tropical lands often is slowed by impoverished seed banks and low rates of seed dispersal. Within degraded landscapes, remnant forests are potential seed sources that could enhance nearby forest succession. The spatial extent that forest can influence succession, however, remains largely unstudied. In abandoned agricultural lands in Kibale National Park, Uganda, re...

Cat Ba National Park is the core zone of Archipelago Biosphere Reserve. It contains quite diverse and unique ecosystems including 776 ha mangrove forest. Although bats park were included in many publications, none recorded from ecosystem. We recently conducted field surveys through wetland areas three horseshoe bat species: Marshall's (Rhinolophus marshalli), Pearson’s pearsonii), least (R. pus...

Increasing global human population and per-capita food consumption are expected to exacerbate the already massive agricultural footprint in tropical ecosystems. Madagascar is home to exceptional levels of biodiversity and is in the midst of severe land-use change, mostly driven by slash-and-burn, smallholder agriculture. Understanding the consequences of these agricultural practices for Malagas...
