Management Strategy for Habitat Restoration
Primary Wildlife Habitat Restoration Objectives:
- Invasive species management
- Strict biosecurity
- Native plant propagation & establishment
- Marine debris removal
- Ecosystem monitoring
The habitat restoration schedule for a summer season is usually between March and September. And the winter schedule is usually between September and March. There is a lot of potentials to study seabird populations and environmental impacts on Kure; however, during this grant period, the majority of field time and resources will be spent on direct physical or chemical removal of invasive plants, greenhouse propagation, outplanting and broadcasting native seeds as well as measuring the outcome metrics.
In 2012, teams of six to seven people increased the treatment area from 69 acres to 116 acres. In 2013, the treatment area was increased to 133 acres. As of September 2014, all vegetated areas across Green Island (188 acres) were incorporated into a rotating treatment schedule that takes 2 to 3 months to complete. Beginning in September 2017, a crew of 8 has been able to decrease that timeframe down to 4 to 6 weeks. This increase in personnel was implemented to prevent Verbesina, Cenchrus and other invasive species from maturing and adding to the seed bank.

Dropseed Sporobolus is a perennial grass colonizing open areas and hard substrates. There is some die-back of older plants in the winter. It is characterized by broad tapering blades, and a relatively closed seed head on a long stalk. It is abundant on the runway, and common on the roads
