Introduction
Using remote sensing in ecological and ecosystem studies I) mostly to map invasive species and their impacts, II) but also to assess the status of Urban Green Infrastructure and to III) develop indicators of ecosystem health, and IV) just recently to quantify the status of traditional orchards.
Started working with airborne hyperspectral and LiDAR data, and now frequently using data from satellites (optical), UAVs (RGB, multispectral) and mobile LiDAR.

Invasive plant species can have high, self-reinforcing impacts on ecosystem structure and functioning that induce permanent changes of ecosystem properties. Therefore, early detection and timely management is required to alleviate ecosystem consequences of invasion. Integrating airborne hyperspectral imagery with LiDAR data can deliver spatially ex...
The intensification of food production systems has resulted in landscape simplification, with trees and hedges disappearing from agricultural land, principally in industrialized countries. However, more recently, the potential of agroforestry systems and small woody landscape features (SWFs), e.g., hedgerows, woodlots, and scattered groups of trees...
Processes that drive plant invasions play out across multiple spatial and temporal scales. Understanding individual steps along the introduction-naturalization-invasion continuum and its drivers is crucial for management. This review, targeting the broad audience of invasion scientists, field ecologists and land managers, summarizes the state-of-th...
Remote sensing is a rapidly advancing technology with a wide range of applications in ecosystem management. This chapter presents a literature review focusing on ecological applications of remote sensing in the context of invasions of Australian Acacia species (‘wattles’) at the global level. Of ten studied species worldwide, only half, namely A. c...
Remote sensing technology is increasingly applied to map the occurrence of invasive plant species, yet its use to map their ecological impact remains limited. Furthermore, invader-induced changes beyond the canopy, as well as the environmental context, are rarely considered. This study aimed to assess the impacts of an invasive tree on ecosystem fu...
Páramos, neotropical high-mountain biomes of the northern Andes, are increasingly threatened by human land use and climate change. Accurate land use/land cover (LULC) mapping is critical for monitoring these pressures. However, persistent cloud cover poses substantial challenges for optical satellite imagery. This study leverages multitemporal Inte...
Soil conditions of croplands are a frequent topic of scientific research. In contrast, less is known about large-scale commercial plantations of perennial crops such as oil palm. Oil palm is a globally important tropical commodity crop which contributes to both food and energy security due to its exceptional productivity. However, oil palm crops ar...
Traditional orchards are distinctive features of cultural landscapes in Central Europe. Despite their high level of ecological importance, they are in decline, and comprehensive spatial data over broad extents, which could enable a trend analysis, are lacking. We analysed traditional orchard maps from 1952 to 1967 and a map from 2010, generated via...
Invasive species can alter the structure and functioning of the invaded ecosystem, but predictions of the impact of invasive species on ecosystem functioning are weak. Invasion is determined by the interplay of invasive species traits, the recipient community, and the environmental context. However, efficient approaches to assess the spatial dimens...
Terrestrial ecosystems such as coniferous forests in Central Europe are experiencing changes in health status following extreme droughts compounding with severe heat waves. The increasing temporal resolution and spatial coverage of earth observation data offer new opportunities to assess these dynamics. Dense time-series of optical satellite data a...
This study evaluates the sensitivity of the Dynamic Habitat Index (DHI), utilizing multitemporal Normalized Difference Vegetation Index (NDVI) data, to changing environmental conditions across Land Use/Land Cover (LULC) types in a central European landscape (2017–2020). We observed distinct DHI characteristics for all LULC types, and the DHI respon...
Das Naturschutz-Monitoring ist ein fester Bestandteil der hessischen Biodiversitätsstrategie. Im Projekt „MonA“ sollen fernerkundungsbasierte Ansätze entwickelt werden, die das Monitoring sowohl von „positiven“ Zielarten des Naturschutzes (seltene Arten der Stromtalwiesen) als auch von gebietsfremden invasiven Pflanzenarten (für Hessen relevante Ar...
Die landesweit verfügbaren Laserscanningdaten in Hesse haben ein großes Potential zum Monitoring von Streuobstwiesen. Viele relevante Eigenschaften auf Einzelbaum- und Bestandsebene lassen sich relativ gut von den Fernerkundungsdaten der hessischen Landesvermessungsdaten ableiten. Hierzu gehören besonders die Anzahl und Position der Bäume, Höhe und...
Agroforestry is a land-use system that combines arable and/or livestock management with tree cultivation, which has been shown to provide a wide range of socio-economic and ecological benefits. It is considered a promising strategy for enhancing resilience of agricultural systems that must remain productive despite increasing environmental and soci...
Context
Combining field-based assessments with remote-sensing proxies of landscape patterns provides the opportunity to monitor terrestrial ecosystem health status in support of sustainable development goals (SDG).
Objectives
Linking qualitative field data with quantitative remote-sensing imagery to map terrestrial ecosystem health (SDG15.3.1 “lan...
Climate change, increasing environmental pollution, continuous loss of biodiversity, and a growing human population with increasing food demand, threaten the functioning of agro-ecosystems and their contribution to people and society. Agroforestry systems promise a number of benefits to enhance nature's contributions to people. There are a wide ran...
The present study aimed to investigate the role of propagule pressure (P), abiotic (A), and biotic (B) factors (collectively indicated as PAB) on the suitability of the Mediterranean island of Sardinia (Italy) to be invaded by the tree Acacia saligna, recently included in the list of invasive alien species of European Union concern.
To this aim, a...
Large and comparatively compact European cities such as Bucharest and Leipzig struggle with considerable urban heat island (UHI) effects characterized by heat and drought together with high concentrations of air pollutants (NO2, SO2, O3, CO2). However, a healthy urban green infrastructure is necessary to reduce the impacts of UHI on human health. T...
Healthy vegetation in cities provides ecosystem services, which contribute to the overall well-being of urban populations, especially in times of climate change and increasing urbanization. More specifically, vegetation monitoring is needed in the context of intensifying and mitigating factors of the Urban Heat Island (UHI) effect. Therefore, fast...
Aim
The impact of invasive species may depend on dissimilarity of their functional traits relative to the native community. Therefore, comparing species traits in a multidimensional space can help to better understand invader impacts, but novel methods are needed to effectively measure multiple traits across diverse plant communities. The main aim...
Mapping tree species at the single-tree level is an active field of research linking ecology and remote sensing. However, the discrimination of tree species requires the selection of the relevant spectral features derived from imagery. We can extract an extensive number of image parameters even from images with a low spectral resolution, such as Re...
Spatial heterogeneity of ecosystems crucially influences plant performance, while in return plant feedbacks on their environment may increase heterogeneous patterns. This is of particular relevance for exotic plant invaders that transform native ecosystems, yet, approaches integrating geospatial information of environmental heterogeneity and plant-...
Hyperspectral remote sensing is an effective tool to discriminate plant species, providing vast potential to trace plant invasions for ecological assessments. However, necessary baseline information for the use of remote sensing data is missing for many high-impact invaders. Furthermore, the identification of the suitable classification algorithms...
Epidermal structures (ES) of leaves are known to affect the functional properties andspectral responses. Spectral studies focused mostly on the effect of hairs or wax layers only. Westudied a wider range of different ES and their impact on spectral properties. Additionally, weidentified spectral regions that allow distinguishing different ES. We us...
Linking remote sensing methodology to stable isotope ecology provides a promising approach to study ecological processes from small to large spatial scales. Here, we show that δ¹⁵N can be detected in fresh leaf reflectance spectra of field samples along a spatial gradient of increasing nitrogen input from an N2-fixing invasive species. However, in...
The invasive shrub, Acacia longifolia, native to southeastern Australia, has a negative impact on vegetation and ecosystem functioning in Portuguese dune ecosystems. In order to spectrally discriminate A. longifolia from other non-native and native species, we developed a classification model based on leaf reflectance spectra (350–2500 nm) and cond...

Acacia spp. are among the most serious plant invaders worldwide, and Acacia longifolia specifically causes problems in Portugal. In this study, we evaluated the impacts of A. longifolia invasion on community structure, light climate, plant diversity and regeneration in pine forests and open stabilized dunes
in northern and southern Portugal. Having...
In water-limited ecosystems, where potential evapotranspiration exceeds precipitation, it is often assumed that plant invasions
will not increase total ecosystem water use, because all available water is evaporated or transpired regardless of vegetation
type. However, invasion by exotic species, with high water use rates, may potentially alter ecos...
Invasive species can have a high impact on ecosystems services, biodiversity and ecosystem functioning. The fusion of high resolution hyperspectral and structural (LiDAR) data shows promising results in detecting invasive plant species especially when occurring in the understory of forests. Imaging spectroscopy enables to derive a specific spectral...
