Restoring fish habitat in the Sandy River Basin

Restoring fish habitat in the Sandy River Basin

The Sandy River Basin is one of many watersheds in the Pacific Northwest that is experiencing the adverse effects of climate change and human impacts. The quality and 1 availability of fish habitat are rapidly declining as the miles of degraded and polluted streams continue to rise. Of the fish species living in the basin, Chinook Salmon, Coho Salmon, and Steelhead are listed under the Endangered Species Act as threatened at the federal level, and Coho Salmon are endangered in Oregon. A majority of streams that provide suitable habitat for these fish are listed as impaired for at least one water quality standard under section 303(d) of the Clean Water Act. Restoration efforts aim to improve the overall health and function of these streams and are often targeted to improve the habitat for specific fish species. In order to assess if the location and type of restoration activities are appropriately applied, it is important to compare the restoration projects to the distribution of threatened fish species and impaired streams.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population.     Via www.vividmaps.com

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
