“…Remote sensing technology, exemplified by Landsat imagery which is orthorectified [8], free [9], and continuous over decades [10], provides an invaluable means of monitoring these ecosystems. With its 16-day revisit cycle, Landsat imagery serves as an efficient, costeffective method for observing land cover changes over extensive and often inaccessible areas [11]. Landsat has been employed to analyze the health of riparian vegetation within the Colorado River Delta through vegetation indexes (VIs) used as proxies of vegetation Remote Sens.…”

Natural resource managers may utilize remotely sensed data to monitor vegetation within their decision-making frameworks for improving habitats. Under binational agreements between the United States and Mexico, seven reaches were targeted for riparian habitat enhancement. Monitoring was carried out using Landsat 8 16-day intervals of the two-band enhanced vegetation index 2 (EVI2) for greenness and actual evapotranspiration (ETa). In-channel water was delivered in 2021 and 2022 at four places in Reach 4. Three reaches (Reaches 4, 5 and 7) showed no discernable difference in EVI2 from reaches that did not receive in-channel water (Reaches 1, 2, 3 and 6). EVI2 in 2021 was higher than 2020 in all reaches except Reach 3, and EVI2 in 2022 was lower than 2021 in all reaches except Reach 7. ET(EVI2) was higher in 2020 than in 2021 and 2022 in all seven reaches; it was highest in Reach 4 (containing restoration sites) in all years. Excluding restoration sites, compared with 2020, unrestored reaches showed that EVI2 minimally increased in 2021 and 2022, while ET(EVI2) minimally decreased despite added water in 2021–2022. Difference maps comparing 2020 (no-flow year) to 2021 and 2022 (in-channel flows) reveal areas in Reaches 5 and 7 where the in-channel flows increased greenness and ET(EVI2).

“…IOP Publishing doi:10.1088/1755-1315/1162/1/012012 2 Plant revegetation is an effort carried out in the restoration of post-coal mining land in carrying out land reclamation [8]. The selection of plants to be used as revegetation plants for post-coal mining must pay attention to the history of land use because the content of residual mining materials can affect the growth of these plants [9,10].…”

“…Drone has advantages when compared to satellite imagery in monitoring land and using it for mapping, including being able to operate relatively quickly and repeatedly, and being able to fly low to produce highresolution images [8,11]. The results of an aerial survey using a drone at a low altitude will produce an aerial photo.…”

Land reclamation and revegetation of post-mines need to be monitored regularly to ensure their progress. The drone is potential due to its high resolution and simplicity in operation and image processing. This study aimed to use the drone as an alternative in identifying and mapping land after the revegetation of coal post-mines in Tanjung Enim, South Sumatra, Indonesia. The research was conducted at the IUP Banko Barat of PT. Bukit Asam Co. Ltd, Indonesia. This research was conducted from September to December 2021. The method used in this study was a manual interpretation by making a delineation of the boundaries between types of revegetation plants in 2014, 2015, 2016, 2017, 2018, 2019, and 2020 planting years. The use of drones in this study was able to determine the distribution of revegetation plants used and produce the revegetation plant distribution map with 5 land cover classes, including Eucalyptus as the dominant species while Angsana (Pterocarpus indicus), Merbau (Intsia sp), Mahogany (Swietenia macrophylla), and Johar (Senna siamea) species with their patchy patterns, covering a total area of 22.52 ha or 66.44%. Eucalyptus is the most dominantly used as revegetation species in the coal post-mine in Tanjung Enim, with an area of 22.39 ha or 66.04% of the land. The drone is reliable for monitoring revegetation progress and may be used as a supplemental tool for evaluating post-mine conditions.

“…Com o uso de sensores espectroscópicos, é possível realizar desde o mapeamento até a extração de informações (através da captação de imagens em diferentes bandas espectrais) da vegetação, bem como utilizá-los para a construção de modelos capazes de estimar com precisão dados da área estudada (Dashpurev et al, 2021).…”

Os manguezais são ecossistemas que abrigam grande biodiversidade vegetal e animal, com papel importante na ciclagem de matéria orgânica e na manutenção dos ecossistemas costeiros, sendo inclusive considerados Áreas de Preservação Permanente. Compreender e caracterizar as propriedades das espécies vegetais do mangue a partir de medidas de reflexão da luz - fotogrametria - para ampliar o entendimento de processos naturais e antrópicos e seus efeitos sobre o manguezal é vital para a realização de previsões e políticas públicas. Este estudo foi realizado na localidade de Acupe, na cidade de Santo Amaro, Bahia, Brasil, utilizando técnicas de geotecnologia, como a aerofotogrametria e técnicas de processamento digital de imagens, além de sensores multiespectrais em multibandas de análise. A partir das coletas, foi verificada a saúde vegetal por meio do índice de vegetação por diferença normalizada. Os resultados apresentam os valores correspondentes à saúde vegetal da região, caracterizando áreas sadias e regiões potencialmente contaminadas, colaborando para a modelagem ambiental da área e levantamento de banco multiparâmetro da Baía de Todos os Santos.
