Environmental monitoring plays a central role in diagnosing climate and management impacts on natural agricultural systems; enhancing the understanding of hydrological processes; optimizing allocation distribution water resources; assessing, forecasting, even preventing disasters. Nowadays, most data collection systems are based upon combination ground-based measurements, manned airborne sensors, satellite observations. These utilized describing both small- large-scale processes, but have...

The rapid spread of invasive plants makes their management increasingly difficult. Remote sensing offers a means fast and efficient monitoring, but still the optimal methodologies remain to be defined. seasonal dynamics spectral characteristics target species are important, since, at certain time vegetation season (e.g. flowering or senescing), often more distinct (or visible beneath canopy). Our aim was establish fast, repeatable cost-efficient, computer-assisted method applicable over...
Tree density affects species diversity in forest plantations. Understory diversity, tree regeneration, and soil physicochemical characteristics were assessed under three planting densities of Pinus massoniana Taizishan Mountains, Hubei, China. There was a higher degree shrub herb lower stands. Total richness for herbs (n = 42) than shrubs 30) but the two groups exhibited similar pattern with greater at stand density. Changes community structure composition more frequent high Community low...
Abstract Aim The spectral variability hypothesis (SVH) suggests a link between variation and plant biodiversity. underlying assumptions are that higher in canopy reflectance (depending on scale) is caused by either (1) habitats or linked vegetation types communities with their specific optical community traits (2) the species themselves traits. Methods SVH was examined several empirical remote‐sensing case studies, which often report some correlation biodiversity‐related variables (mostly...
Abstract Climate change and other global drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for species their elevational ranges. Range shifts are often idiosyncratic difficult generalize, partly due variation sampling methods. There thus a need standardized monitoring strategy that can be applied across mountain regions assess distribution changes community turnover of native non‐native over space time. Here, we...
Summary The initiation of an invasion event is rarely dated in studies alien plants. Data from aerial photographs documenting the outset facilitate quantification rate spread, allowing researchers to analyse species’ population dynamics and providing a basis for management. For 10 sites invaded by Heracleum mantegazzianum Slavkovský les, Czech Republic, 11 sampling dates between 1947 (before started) 2000 were analysed. area covered invader was measured digitally 60‐ha section landscape,...
To successfully fight plant invasions, new methods enabling fast and efficient monitoring are needed, remote sensing can make their management more less expensive. However, the data resolution, cost, availability be limiting. Optimal solution depends on species characteristics, where spectral spatial resolution compensate each other to some extent, phenology plays an important role. Available high satellite sufficient for recognition of that distinct either large or form uniform patches at...
Background Coppicing was one of the most important forest management systems in Europe documented prehistory as well Middle Ages. However, coppicing gradually abandoned by mid-20th century, which has altered ecosystem structure, diversity and function coppice woods.

Understanding the spatial dynamics of invasive alien plants is a growing concern for many scientists and land managers hoping to effectively tackle invasions or mitigate their impacts. Consequently, there an urgent need development efficient tools large scale mapping plant populations monitoring colonization fronts. Remote sensing using very high resolution satellite Unmanned Aerial Vehicle (UAV) imagery increasingly considered such purposes. Here, we assessed potential several single-...
Small unmanned aerial systems (UASs) equipped with an optical camera are a cost-effective strategy for topographic surveys. These low-cost UASs can provide useful information three-dimensional (3D) reconstruction even if they low-quality navigation system. To ensure the production of high-quality models, careful consideration flight mode and proper distribution ground control points required. this end, commercial UAS was adopted to monitor small earthen dam using different combinations...
Abstract. Invasive species spread rapidly and their eradication is difficult. New methods enabling fast efficient monitoring are urgently needed for successful control. Remote sensing can improve early detection of invading plants make management more less expensive. In an ongoing project in the Czech Republic, we aim at developing innovative mapping invasive plant (semi-automatic algorithms) by using purposely designed unmanned aircraft (UAV). We examine possibilities two tree herb species....
Abstract Global climate and land use change are causing woody plant encroachment in arctic, alpine, arid/semi‐arid ecosystems around the world, yet our understanding of belowground impacts this phenomenon is limited. We conducted a globally distributed field study 13 alpine sites across four continents undergoing sampled soils from both encroached nearby herbaceous community types. found that influenced soil microbial richness composition based on multiple factors including traits, site...
