Transcription

1 Wailua, Maui DAR Watershed Code: Wailua, Maui WATERSHED FEATURES Wailua watershed occurs on the island of Maui. The Hawaiian meaning of the name is two waters. The area of the watershed is 1.9 square mi (4.9 square km), with maximum elevation of 3734 ft (1138 m). The watershed's DAR cluster code is not yet determined. The percent of the watershed in the different land use districts is as follows: 26.9% agricultural, 73.1% conservation, 0% rural, and 0% urban. Land Stewardship: Percentage of the land in the watershed managed or controlled by the corresponding agency or entity. Note that this is not necessarily ownership.

2 Land Management Status: Percentage of the watershed in the categories of biodiversity protection and management created by the Hawaii GAP program. Permanent Biodiversity Managed for Multiple Protected but Protection Uses Unmanaged Unprotected Land Use: Areas of the various categories of land use. These data are based on NOAA C- CAP remote sensing project.

Total stream length is 6.5 mi (10.5 km). The terminal stream order is 2. Reach Type Percentages: The percentage of the stream's channel length in each of the reach type categories. Estuary Lower Middle Upper Headwaters The following stream(s) occur in the watershed: Honolewa Paihi Wailua BIOTIC SAMPLING EFFORT Biotic samples were gathered in the following year(s):

3 Distribution of Biotic Sampling: The number of survey locations that were sampled in the various reach types. Survey type Estuary Lower Middle Upper Headwaters DAR General Surveys Published Report Species List Native Species BIOTA INFORMATION Native Species Fish Awaous guamensis Insects Hydroptila sp. Lentipes concolor Sicyopterus stimpsoni Introduced Species Crustaceans Macrobrachium lar Snails Cipangopaludina chinensis Pila conica Pomacea canaliculata Species Distributions: Presence (P) of species in different stream reaches. Scientific Name Status Estuary Lower Middle Upper Headwaters Lentipes concolor Endemic P Awaous guamensis Indigenous P Macrobrachium lar Introduced P Hydroptila sp. Undetermined P HISTORIC RANKINGS Historic Rankings: These are rankings of streams from historical studies. "Yes" means the stream was considered worthy of protection by that method. Some methods include non-biotic data in their determination. See Atlas Key for details. Multi-Attribute Prioritization of Streams - Potential Heritage Streams (1998): No Hawaii Stream Assessment Rank (1990): Outstanding U.S. Fish and Wildlife Service High Quality Stream (1988): Yes The Nature Conservancy- Priority Aquatic Sites (1985): No National Park Service - Nationwide Rivers Inventory (1982): No Current DAR Decision Rule Status: The following criteria are used by DAR to consider the biotic importance of streams. "Yes" means that watershed has that quality. Native Insect Diversity Native Macrofauna Absence of Priority 1 > 19 spp. Diversity > 5 spp. Introduced No No Yes 691
