Native to the Gulf of Mexico, Karenia brevis is a toxic dinoflagellate that blooms almost annually off the west coast of Florida. K. brevis blooms are not a new phenomenon on the west Florida shelf, and ships' logs suggest bloom-related events (fish kills) dating back to the 1500s. Coastal regions of Florida have experienced some of the most rapid population growth and development in the United States.

As a 200,000-acre natural oasis in the densely populated mid-Atlantic region, Shenandoah National Park is a refuge for both wildlife and people. This booklet illustrates the unique natural resources in the park and demonstrates the need for natural resource monitoring. It also explores the natural processes and human-caused activities that pose a threat to park ecosystems, and investigates the selection of vital signs—indicators of natural resource conditions.

The fragile natural and cultural resources such as anchianline pools, fishponds, and the nearshore marine areas are reliant to varying degrees on the groundwater that filters into Kaloko-Honokohau National Historical Park. Excessive withdrawal of groundwater by development wells upslope and outside the park may threaten those resources with drying out and saltwater intrusion, thereby putting native plant and animals that live in those environments at risk. This brochure outlines these issues.

Harmful algal blooms (HABs) have increased in abundance and severity around the world in recent decades. Among coastal HABs, benthic cyanobacteria blooms, particularly Lyngbya spp., are becoming more numerous and persistent in tropical and subtropical environments. These species have become increasingly problematic in the near-shore waters of Florida, and it has been suggested that this may be in part caused by nutrient enrichment resulting from highly developed coastal habitats.
