Riparian Ecology Management Study (REMS) Washington Dept. of Ecology, Lacey, WA U.S.A / J. Janisch and W. Ehinger 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

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

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.

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

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

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

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

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

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

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

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

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

continuous, top=flow, weir=flowcontinuous, top=, weir=flow in the absence of surface flow buffer air temp range more like clearcuts than reference basins how about buffers with and without flowing streams? air temp pressure from outside water temp pressure from inside

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

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

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

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