Two broad objectives are addressed by this protocol: 1) Determine the annual status and trends of invertebrate species diversity, abundance and community metrics, and 2) Relate the invertebrate community to overall water quality through quantification of metrics related to species richness, abundance and diversity and region specific multi-metric indices as indicators of water quality and habitat condition

Homestead National Monument of America (HOME) is located in the southeast corner of Nebraska (Figure 1). The Monument was established in 1936 to commemorate the Homestead Act of 1862, a law intended to stimulate the agricultural economy through free land deeds. HOME includes the 160 acres once owned by Daniel Freeman, who is credited with filing the first homestead claim in the United States (Hutchinson, 1992). For the settlers of the Great Plains, the prairie initially provided food for livestock and housing by way of sod. A great deal of original prairie has since been converted for...

Long-term trends in deer abundance provide one measure of assessing their potential as a problem for a park. Documenting long-term patterns in deer numbers allows one to evaluate correlations with changes in vegetation (e.g., through restoration of the cultural landscape). With this information resource managers can more effectively identify and potentially mitigate damage caused to vegetation communities and endangered plant populations by deer. Monitoring data also helps managers assess safety risks from collisions and disease transmission. Long-term monitoring of deer numbers is critical...

It is against a backdrop of vanishing or altered ecosystems, declining bird populations and the unique role that National Park Service lands can play in conserving threatened bird species that the authors propose monitoring avian communities on National Park Service lands within the HTLN. Long-term trends in the community composition and abundance of breeding bird populations provide one measure for assessing the ecological integrity and sustainability of ecosystems. Long-term patterns in community composition and species abundance in relation to changes in the structural diversity of...

During surveys in 2006, the authors documented 13 invasive, exotic plant species and the native Eastern red cedar on Pea Ridge National Military Park. The survey focused on the relatively mature forests at the park to the exclusion of old fields and successional forests.
