The aim of this report card is to provide a transparent, timely, and geographically detailed assessment of 2024 Coastal Bays health. Coastal Bays health is defined as the progress of four water quality indicators (total nitrogen, total phosphorus, chlorophyll a, dissolved oxygen) and two biotic indicators (seagrass, hard clams) toward scientifically derived ecological thresholds or goals.

The Loudoun Wildlife Conservancy produced its first-ever report card in 2025. Since 1995, Loudoun Wildlife Conservancy has worked to protect, preserve, and restore wildlife habitat through community science, advocacy, education, and habitat restoration. Our programs engage residents of all ages in meaningful experiences that inspire action and stewardship for Loudoun County, Virginia’s natural resources.

Vegetated buffer strips (VBS) are widely used to mitigate agricultural non-point source pollution yet reported retention efficiencies vary considerably across different landscapes. We synthesized 409 observations extracted from 91 peer-reviewed publications to evaluate critical determinants of VBS retention efficiency for agricultural runoff, focusing specifically on total nitrogen (TN), total phosphorus (TP), and total suspended solids (TSS).

In previous water quality modeling studies in Chesapeake Bay, the severity of summer hypoxia tended to be underestimated in the mid-lower Bay area. The underlying reason has not been well understood. In this study, we test a new hypothesis with respect to the estuary–ocean exchange.

Parachute science is the problematic and extractive practice of non-local researchers taking data, knowledge and information from communities of which they are not members, failing to engage the local community and local scientists, marginalizing them in most aspects of the research, and using the results to their own benefit.

Biodiversity can confer temporal stability to ecosystem processes through asynchrony in species' abundances and may promote asynchrony and stability of commercial fishing harvests derived from exploited species. However, the linkages between asynchrony in the population dynamics of commercially harvested species and asynchrony of associated harvests have been difficult to resolve due to ecological, social, and economic dynamics that mediate resource extraction.
