Remote sensing (RS) has become a key tool for identifying, tracking, and managing invasive alien plant species (IAPS), particularly as biological invasions intensify under climate change, land-use change, and urban expansion. Despite rapid technological advances, RS applications for IAPS remain highly heterogeneous with respect to sensor types, spatial and spectral resolution, analytical methods, validation strategies, and species-specific detectability. This structured literature review synthesises global evidence on RS applications for IAPS published between 2000 and 2025, with particular attention to temperate ecosystems and the operational relevance of selected high-priority taxa for European management contexts: Ailanthus altissima, Asclepias syriaca, Heracleum mantegazzianum, Solidago spp., Reynoutria japonica, Impatiens glandulifera, Celastrus orbiculatus, Pueraria montana var. lobata, Phytolacca americana, and Buddleja davidii. We screened the Web of Science (WoS) and Scopus databases and analysed 219 eligible empirical studies according to sensor type, spatial and temporal resolution, analytical approach, validation design, reported accuracy, and ecological context. Multispectral satellite data dominated regional-scale mapping, whereas airborne hyperspectral imagery and UAV-based platforms were frequently used for fine-scale species discrimination and monitoring, especially for spectrally or structurally distinctive taxa. UAV-based approaches were valuable for local detection and post-eradication monitoring, although performance was often constrained by shadowing, canopy structure, and habitat heterogeneity. Recent trends, particularly after 2017, with a pronounced increase during 2023–2025, include the increasing use of deep learning, street-level imagery, crowdsourced photographs, and multisource data fusion. Species detectability varied widely among taxa and was strongly influenced by phenology, canopy position, habitat configuration, reference-data quality, and sensor characteristics. Overall, no single sensor or analytical approach was universally optimal. Instead, combining satellite, UAV, and ground-based data with species-specific ecological knowledge can improve detection efficiency, transferability, and operational monitoring of IAPS across global and temperate management contexts.
