Presentation Transcript

  1. Riparian Ecology Management Study (REMS) • WA DNR project: determine best management • for small non-fish basins. if buffers, what • design? • last state forested flowing water type • fish streams, amphibians, small mammals, invertebrates high in watershed TEMPERATURE, PART II AIR (+ a little water) • flower pots w/camo paint, vents • sensor suspended by string • ~1.5 m above forest floor • along stream, ~2-5 m off-channel • -so inside buffer, stream bubble • -and multiple sensors per stream • also mainstem and transects Washington Dept. of Ecology, Lacey, WA U.S.A / J. Janisch and W. Ehinger

  2. EXPECTED TO MAKE MORE HEADWAY BUT DIFFICULT SO, TOUR THE DATA EXAMPLES, ALL RAW DATA—JUL AND AUG

  3. design • DNR LANDS, 8 STANDS TOTAL • LATERAL STREAMS, SEASONAL AND PERENNIAL • BACI: REF CC FIX (ie, continuous) VAR • AIR TEMPERATURE ONLY MONITORED IN 6 • TEMP COLLECTION TO CONTINUE 2+ YEARS • POST-HARVEST • DRYING, INTERIOR STAND TEMP, TRT RESPONSE • DOES  AIR TEMP TRANSLATE INTO WATER TEMP? • Type 5 by definition seasonal Type 4/5: bfw<2ft; with or without well-defined channels and areas of perennial and/or seasonal seepage.

  4. Two regions: Black Hills • ~inland (70km) • Willapa Hills • ~coastal (25 km) • 3 stands /region N Washington, USA HW network CHANNEL, CONFLUENCE WEIR TEMP, PAIRED 200+ SENSORS 30 MIN READINGS M FOCUS

  5. PRE-HARVEST: SOME SOURCES OF VARIATION (gradient) NOV 03 AUG 05 harvest period study period FEB 07 JUN 03

  6. POST-HARVEST: ADDITIONAL VARIATION drying missing treatments /anova unbalanced some blowdown /buffer width variation

  7. DESPITE VARIATION, ARE PRE-HARVEST AIR TEMPS BETWEEN REFERENCE BASINS SIMILAR? PRE-HARVEST (2003) max air temp at weir (low) REFERENCE BASINS INLAND COASTAL range of mean about 5°C

  8. HOW ABOUT BASINS WITHIN A STAND? PRE-HARVEST 2003 max air temp at weir (low) INLAND (BH) COASTAL (WH) dry by oct 1 dry range 3-4°C MS LR

  9. HOW ABOUT WATER TEMP--- DOES IT CORRELATE WITH WATER TEMP? PRE-HARVEST 2003 air AND water temp at weir (low) REFERENCE BASINS water only compact signal long and short streams consistent source drying water temp at weir, max july-aug unclear. multi-year data and other details may resolve air temp at weir, max july-aug

  10. how about post harvest, clearcut vs buffered? POST HARVEST 2006 AIR ONLY CLEARCUT perennial drying, top CONTINUOUS UPPER STATION always dry drying, bottom LOWER STATION blowdown drying

  11. POST-HARVEST EXAMPLE (2006): WH (coastal) headwall different than weir REFERENCE CLEARCUT 2003 2006 2003 2006 convergence, effect penetration? mainstem buffer drying? water temp at weir, max july-aug road harvest air temp at weir, max july-aug air temp at headwall, max july-aug cc: min &max AT increase water temp increases EF_b

  12. 2006 POST-HARVEST EXAMPLE: WH (coastal) headwall different than weir but reversed REFERENCE CONTINUOUS 2003 2006 2003 2006 more blowdown, convergence water temp at weir, max july-aug road harvest air temp at weir, max july-aug air temp at headwall, max july-aug EF_c

  13. how about buffers with and without flowing streams? continuous, top=flow, weir=flow continuous, top=<no flow>, weir=flow air temp pressure from outside water temp pressure from inside in the absence of surface flow buffer air temp range more like clearcuts than reference basins

  14. CANOPY PHOTOGRAPHY, BEFORE AND AFTER HAVEST shade: buffers different from clearcut air temp: when channel is dry buffers seem like clearcut harvest

  15. summary buffer air temperature and shade more like clearcuts or reference basins? does air temp translate into water temp? does water temp track air temp? • data still very preliminary but • buffer air temp seems more like clearcut • could be all edge • buffer shade seems more like reference • air temp signal is different at headwall than weir • but seem to converge /creep over time • need to explore air temp vs shade as water temp • driver • not clear yet

  16. what next? • much data coding needed • remove annual climate signal • autocorrelation • sine/cosine regression model • trim data to balance anova? • paired basin study? • slash accumulation • riparian vegetation re-growth • other data sets

  17. surface flow consistent pre vs. post stream wets up after harvest: evapotrans
