Number of unique groundwater-dependent ecosystems in HUC6 watersheds, Oregon

This dataset is HUC6 watersheds in Oregon attributed with summary information for species and ecosystems that occur in landscapes where they could be groundwater-dependent, according to analyses conducted by The Nature Conservancy in Oregon.

This dataset is part of a larger groundwater project across the Pacific NW (Brown et al. 2009) region which has two primary goals: (1) develop tools to identify where and how groundwater is important to biodiversity conservation and (2) assess the pressing threats to the quantity and quality of that groundwater and develop strategies to abate those threats. Data and analyses conducted are intended for use at a statewide scale. Therefore, more detailed mapping may be necessary at local scales. For more information please contact the Oregon Field Office of The Nature Conservancy or see the following website http://www.waconservation.org.

Note: In this dataset, there are a maximum of five indicators of unique groundwater-dependent ecosystems. These include the presence of groundwater-dependent: springs, wetlands, rivers, lakes, and obligate species.
