Mark DMAs & Collect Data Identify Plants on the DMA Take photos Determine sample interval (2.75 m = 40 plots each side for a 110 m DMA) Use random # to start first plot Uses 42 x 50 cm plot (2 Daubenmires) Locate Greenline as per rules Follow rules exactly for each procedure
2
Located by pacing ▲ ▲ Monitoring the DMA (the turn-around) Sample entire length of DMA, Both sides Sample entire length of DMA, Both sides At the top of the DMA, measure the distance from last plot to marker, cross to the other side measure the remaining part of the plot interval & place the frame for the next plot. Continue downstream to the lower marker. At the top of the DMA, measure the distance from last plot to marker, cross to the other side measure the remaining part of the plot interval & place the frame for the next plot. Continue downstream to the lower marker.

Important for precision - repeatability

A. Perennial Herbaceous Vegetation, Shrub/Tree Seedlings, Embedded Rock, Anchored Wood (or any combination) …the length & width of 1 quadrat (20 by 50 cm) with no patches of bare ground, litter, or nonvascular plants greater than 10 percent of the plot (10 by 10 cm - 4”) & that meet all rules. Rocks <15 cm = bare ground. OR B. Overstory of Young and/or Mature Shrubs or Trees
