Monitoring of environmental restoration is essential to communicate progress and improve outcomes current future projects, but typically done in a very limited capacity due budget personnel constraints. Unoccupied aerial vehicles (UAVs) have been used variety natural human-influenced environments found be time- cost-efficient, not yet widely applied contexts. In this study, we evaluated the utility UAVs as an innovative tool for monitoring tidal marsh restoration. We first optimized methods creating high-resolution orthomosaics Structure from Motion digital elevation models UAV imagery by conducting experiments determine optimal density ground control points (GCPs) flight altitude topography new vegetation. raw classified before, during, after construction site with various audiences inform adaptive management. that could achieve 1.1 cm vertical accuracy our using 2.1 GCPs per hectare at 50 m. A lower 30 m was more ideal capturing patchy early plant cover while still being efficient enough entire 25-hectare site. products were valuable several applications, including calculating volume soil moved during construction, tracking whether targets achieved, quantifying examining patterns vegetation development, topographic change subsidence, erosion, creek development. advantageous ability survey areas difficult access on foot, capture spatial variation, tailor timing data collection research needs, collect large amount accurate rapidly relatively low cost, though some compromise detail compared field monitoring. summary, informed planning, implementation phases major landscape project many habitats.

Drone-based assessment of microsite-scale hydrological processes promoted by restoration actions in early post-mining ecological restoration stages

A successful choice of post-mining restoration activities in dry climates may depend on relevant features related to topographic characteristics, hydrological processes and vegetation development, which will determine functional recovery these ecosystems. The combination different techniques reestablish vegetation, such as sowing plantation, implies the interspersion bare-soil areas with vegetated early plant development stages, result an associated mosaic hydrologic functioning. In this study, we conducted a drone-based assessment disentangle role played by microsite-scale (i.e., planting hole slope, sink volume capacity, individual catchment area, Flow Length Index) promoted actions soil protection hillside scale. Based two contrasting scenarios (Steep Smooth hillside), applied treatments conditioned microtopographic scale and, therefore, resource redistribution. main results showed higher functionality smooth hillsides than steep hillside, resulted greater water availability bigger patches. By addressing microsite scale, our study contributes substantially prior knowledge factors for ecosystem success. It also demonstrates that high-resolution drone images can be very useful tool monitoring actions, especially large, inaccessible unstable restored areas.

UAVs for monitoring responses of regenerating forests under increasing climate change-driven droughts - a review

IOP Conference Series Earth and Environmental Science, Год журнала: 2023, Номер 1167(1), С. 012030 - 012030

Abstract The impact of climate change-driven droughts on regenerating forests is poorly understood due to the complexities involved in regeneration processes and difficulties measuring relevant parameters with sufficient spatial temporal resolution a timely manner. Drought increases tree mortality both undisturbed disturbed may influence forest dynamics from seed germination recruitment, growth, survival seedlings. Seedlings small saplings be more susceptible changes water availability than larger individuals their shallower roots that unable reach deeper, moist soil layers, uneven competition adult trees for moisture. potential range shifts local extinction drought-sensitive species can also result community composition diversity loss at different scales. There need precise low-cost monitoring systems facilitate better capturing such restoration measures. objective this paper study use UAVs (Unmanned Aerial Vehicles) responses under increasing droughts. have several advantages over traditional field-based techniques flexibility selecting required spatiotemporal other remote sensing methods, making them promising tool recovery. Although further research ensure accuracy effectiveness UAV-facilitated measures regeneration, possess great management event occurrences climate-change driven

Monitoring ecological characteristics of a tallgrass prairie using an unmanned aerial vehicle

Restoration Ecology, Год журнала: 2020, Номер 29(S1)

Опубликована: Дек. 15, 2020

Site‐specific conditions, climate, and management decisions all dictate the establishment composition of desired plant communities within grassland restorations. The uncertainty, complexity, large size restorations necessitate monitoring across spatial temporal scales. Remote sensing with unmanned aerial vehicles (UAVs) may provide a tool to monitor restored at various scales, but many potential applications are still unknown. In tallgrass prairie restoration located in Franklin Grove, IL, we used UAV‐based multispectral imagery assess ability spectral indices predict ecological characteristics (plant community, traits, soil properties) summer 2017. Using 19 sites, calculated moments 26 vegetation four bands (green, red, red edge, near infrared). Models based on each moment model were estimated using ridge regression training subset 15 sites. Each tested for significant error reduction against null model. We predicted mean graminoid cover, dead aboveground biomass, dry mass, K reductions cross‐validated root square error. Averaged coefficients determined from cross‐validation models develop final predictive successfully characteristics. Graminoid cover potassium one sites while other two not any site. This study provides path toward new level ease precision community dynamics grasslands.

Low‐cost tools for large‐scale seed scarification: efficiency in two species from South American arid lands

Restoration Ecology, Год журнала: 2024, Номер 32(6)

Опубликована: Янв. 31, 2024

The use of native plants for arid land restoration requires the application pre‐germination treatments to alleviate seed dormancy mechanisms. As it is known, scarification allows several valuable species overcome primary forms dormancy. However, supplying large quantities scarified seeds at a low cost represents significant challenge. In this context, our objective was evaluate locally constructed machines accessible people degraded lands in state poverty. effectiveness evaluated by comparing two shrubs from South American lands, Larrea divaricata and L. cuneifolia . Four were applied: control (T0), mechanical with hand drill equipped sandpaper on its head (T1), 15 seconds (T2) 30 (T3) self‐constructed machine, capable regulating pressure speed. For both species, germination probability higher T2 (0.82 ± 0.02) compared T0 (0.28 0.03) T1 (0.65 0.03). T3 presented intermediate values (0.75 but did not differ significantly T2. Our results show tool upscale seed‐based lands.
