Fauna Positively Identified at the Wheeler Bay Wildlife Sanctuary

As the habitat value of the Wheeler Bay Wildlife Sanctuary has been enhanced, we have observed an increase in the number and variety of birds, mammals and insects at this site. The following is a list of fauna that was positively identified living at, or stopping over at the wildlife sanctuary. This list understates the variety of fauna because many other species were observed but not positively identified.

Vegetation Being Added to or Removed from the Clark Island Wildlife Refuge

Invasive plants are introduced species that thrive in areas beyond their natural range of dispersal. These plants are characteristically adaptable, aggressive, and have a high reproductive capacity. Their vigor combined with a lack of natural enemies often leads to outbreak populations. Removing them will allow native species to thrive on the refuge.

Invasive Species Being Systematically Removed

Autumn Olive (Elaeagnus umbellata)

Japanese Honeysuckle (Lonicera japonica)

Purple Loosestrife (Lythrum salicaria)

(Originally cultivated for wildlife habitat but it crowds out native species)

Restored Wetlands
