The Pacific Northwest is highly variable. https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391148246484-8YG071S31UTFN8DSQADN/UASlogo.jpg Forest disturbance and water supplies https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391148233867-G9EUS73A7U50IOEB0Y0M/ESOC+logo.png Forest disturbance and water supplies https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391148773796-URUVW9TFUABJ1I1XF9H5/NSF_Logo.jpg Forest disturbance and water supplies https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391148281820-JXFEM3FDSBBJ8IIXMFEA/WWA_logo_317.png Forest disturbance and water supplies https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391149373943-OBNA0HJOG8AL11N84MBO/CU+logo.png Forest disturbance and water supplies https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1457724721182-PNW54HHFG99XOJPTH7Z0/image-asset.jpeg Forest disturbance and water supplies The most explanatory variables for post-disturbance watershed response, with predictor variables standardized and binned into response groups (y-axis shows standard deviations from the mean). Differences among groups illustrate their associative values relative to watershed response in terms of water yield (top) or streamflow timing (bottom). Large values of percent forest disturbed were strongly associated with observed increases in water yield. High snow percentage was associated with insensitivity to disturbances in terms of streamflow timing. Numbers indicate significantly different groups (p < 0.05, pairwise Kruskal-Wallis rank sum test). Boxplots show 25th and 75th percentiles, whiskers extent to 1.5 the interquartile range beyond those percentiles. Outliers shown as points. https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1473375399538-UQI87ATZIYPB2XQSQFY7/image-asset.jpeg Forest disturbance and water supplies There are many forested watersheds (and non-forested) across the country that are monitored for water. We can use these to get at what exactly makes a watershed produce more water after a disturbance, or less, or change the timing of the delivery of that water. Details: (a) Percent forest loss in the largest disturbance event (2001-2010) and the original percent forested for the undammed watersheds, with a range of disturbance percentages, (b) post-disturbance response group distribution in terms of deviations in flow timing, and (c) deviations in water yield. Response groups are similar watersheds that had similar behavior in regards to either total water yield or timing (treated independently). Boxplots show 25th and 75th percentiles, whiskers extent to 1.5 the interquartile range beyond those percentiles. Outliers shown as points. https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1391148068310-YQDHXNCVWUM4HESZ4BN4/Spruce+beelte+mortality+near+Steamboat+Springs%2C+Colorado Forest disturbance and water supplies Dead spruce near Steamboat Springs, Colorado http://www.brianbuma.com/new-page-2 daily 0.75 2016-04-08 http://www.brianbuma.com/new-page daily 0.75 2016-04-08 http://www.brianbuma.com/new-page-4 daily 0.75 2016-04-08 http://www.brianbuma.com/greenland daily 0.75 2024-02-20 https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/0f40d38a-3560-40f0-a7e5-e4b66285fabc/DSC_2252.jpg Greenland Explorations Photo credit: Jeff Kerby http://www.brianbuma.com/plant-community-succession-over-100-years daily 0.75 2018-09-05 https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1508474559916-JCAR7FHV6W533FAIFOK4/Cross+Rock+time+series+new+subset.jpg Plant community succession over 100 years Shots of "Cross Rock," an important navigational tool.

There is a pulse of high species richness apparent across all plots early, about 50 years after glacial recession, followed by a decline as a few species take over (generally Salix spp) and understory diversity declines. Other metrics of community diversity being calculated currently (Oct 2017). https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1479927888205-RL6VAWFZW73K95YZ8JSV/image-asset.jpeg Plant community succession over 100 years Soil characteristics as a function of plot location relative to the community source populations (near or far) and age of plots. "Near" plots are closer to the entrance to Glacier Bay, and have generally had faster community development. https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1500834041903-9NC07GV40QH8K1471SBF/Arrow+Rock.jpg Plant community succession over 100 years Dr. Sarah Bisbing sits on Arrow Rock, one of the key navigational points from 1916. Comparative images from 1926 (top right) and 1941 (likely) are shown. Interesting factoid - the modern 2016 picture has >3000 people in it. Look close and you can see a cruise ship in the background, a very different reality from what Cooper found in 1916. Also, note how different the alluvial fan in the background is. The photos are from the same location, but in 1926 the fan was much, much smaller (and in 1941). That isn't tidal. It's a combination of the fan growing (it's quite shallow right off the edge, makes for some interesting kayaking) and isostatic rebound, which is very rapid in this portion of the bay. https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1486142994989-BCA3BVAAXULRXHR87GK7/All+quadrats+copy+%282%29.jpg Plant community succession over 100 years Current known pictures of the permanent plot network.

Both decline with time, a result of a small number of species taking over. Despite increasing richness, the majority of plots are now covered by the same species, so effective diversity seems lower. Date for middle years being worked up currently. http://www.brianbuma.com/big-carbon-ecosystems-and-economies daily 0.75 2024-02-20 https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386698348-K4H78JS54AQ55BZHM82G/20190124_072726.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386827433-NB6EMZLV0ZQCG0GITH2H/0001i8989_190118_00010.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386753297-TNS8CXGQUPLO1P3DVEVJ/DSC07393.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386817124-I2WAMZ3F3KXOGHOMNUBY/20190201_110723.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386766541-LKVH2VBPLF6W6A7ST1PM/DSC06795.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386778351-5A7LE6OEB93UDGBIRI5U/DSC06445.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386650652-47SR94ADSNY7YBRSNNEP/20190127_080226%280%29.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386853032-ERGJEBHC0GVGEUWLRJNA/ian+1.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386872793-JW1R298J687MUKBXVCOP/GOPR2890-2.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386877365-88T3OERJU7HECU78SYYM/OBP_4432.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386916794-J2U2A1UI18IXU75TNMJK/DSC07641.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386941640-NNHY0CYM4Q5N9FM9CEAA/_A8A6192mkiv.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/1708386949222-EVR4DB9TD3HD3FL5SI66/_A8A5414mkiv.jpg The Southern Edge https://images.squarespace-cdn.com/content/v1/52eabf36e4b0efa59d540841/b0fe4b6c-56e0-46b4-8363-84e88283c7a2/_A8A5736mkiv.jpg The Southern Edge Facing into the wind, Isla Hornos, Chile.
