Ambient air pollution, detrimental built and social environments, isolation (SI), low socioeconomic status (SES), rural (versus urban) residence have been associated with cognitive decline risk of Alzheimer's disease related dementias (ADRD). Research is needed to investigate the influence ambient pollution environments on SI among rural, disadvantaged, ethnic minority communities. To address this gap, cohort study will recruit an ethnoracially diverse, Florida sample in geographic proximity seasonal agricultural burning.

Spatiotemporal Vegetation Dynamics, Forest Loss, and Recovery: Multidecadal Analysis of the U.S. Triple Crown National Scenic Trail Network

Remote Sensing, Journal Year: 2025, Volume and Issue: 17(7), P. 1142 - 1142

Published: March 24, 2025

The U.S. National Scenic Trail system, encompassing over 12,000 km of hiking trails along the Appalachian (AT), Continental Divide (CDT), and Pacific Crest (PCT), provides critical vegetation corridors that protect diverse forest, savannah, grassland ecosystems. These ecosystems represent essential habitats facing increasing environmental pressures. This study offers a landscape-scale analysis dynamics across 2 wide conservation corridor (20,556 km2), utilizing multidecadal Landsat MODIS satellite data via Google Earth Engine API to assess health, forest disturbance recovery, phenological shifts. results reveal loss, primarily driven by wildfire, impacted 1248 km2 land (9.5% in AT, 39% CDT, 51% PCT) from 2001 2023. Moderate severe wildfires PCT (713 burn area) CDT (350 exacerbated stress facilitated transition grassland. LandTrendr at 15 sample sites revealed slow, multi-year recovery based on temporal segmentation spectral indices (NBR, NDVI, NDWI, Tasseled Cap). post-disturbance NBR values remained significantly reduced, averaging 0.31 five years post-event compared 0.6 prior disturbance. Variations phenology were documented, with no significant trends seasonal advancement or delay. establishes robust baseline for change trail highlighting need further research explore localized trends. Given accelerating impacts climate wildfire frequency, findings underscore necessity adaptive strategies guide management ensure long-term stability sustainability cover these vital areas.
