We collected four soil samples at the 29 phenology study points shown. Soil analysis at the NDSU Soil Lab provides N, P, K, Ca, Mg, Na, pH, and organic matter data for long-term site characterizations and comparisons.

We plan to install 5 soil moisture potential probes at the 19 points shown. Data loggers at each site will wirelessly transmit data to a base station via either radio or cellular signal. Nick Franczyk and I are testing some demo units to determine the best transmission system for our topography.

The decumbent ecotype of antelope bitterbrush can regenerate by seed, layering, and resprouting. Multiple reproductive strategies may make them more successful than the upright growth form in restoration efforts. We collected decumbent bitterbrush seeds in summer 2012 and grew seedlings in the lab in spring 2013. We planted 110 young shrubs in the experimental garden and installed drip irrigation to help them through the summer. Hopefully, the seedlings will grow in the decumbent form and provide a reliable seed source for future plantings.

Field Work: § Collect soil samples from 29 phenology study sites for nutrient analysis § Lay weed mat in experimental garden § Plant 110 decumbent bitterbrush seedlings in experimental garden § Install drip irrigation to bitterbrush
