This deer was shot with a lead bullet. The bright white spots scattered throughout its body are fragments of lead from that bullet. These fragments can be eaten by scavengers, such as eagles, when they feed upon a gut pile or carcass left out in the field.

Golden eagle populations in North America are either holding steady or possibly in decline and below the number that which the environment can support.

The black oystercatcher, a keystone species in nearshore ecosystems, plays an important role in structuring nearshore systems and is highly susceptible to human disturbance. Current inventory and monitoring efforts may not adequately address the information needs for estimating long-term trends for this species.

Examining environmental deoxyribonucleic acid (eDNA) in water samples has demonstrated promise for identifying fish species present in water bodies. However, whether or not this same approach can be used to assess relative abundance, biomass, and species composition in large (greater than [>] 200-hectare) waterbodies is unclear.

Restoring areas infested with invasive species that carry catastrophic fire is a top priority for the Restoration Assessment and Monitoring Program for the Southest (RAMPS) and our partners.
