Instructions for taking moss samples for proximate analysis (TC, TN, and TP) 1. Do this once at each of the Moss Point Transect sites. Do this as late as possible in the season. But any time after mid-July will do. The primary moss to sample is Hygrohypnum. However, make a concerted effort to sample Schistidium if you can find it. It may be hard to find. Sample the leafy liverwort (Solenostoma) in the Recovery reach only. If you happen to find Fontinalis, sample it. 2. At each site, pick healthy looking moss specimens from at least 5 locations around the riffle (if you can). A healthy finger full (not a big hand full) will do for a subsample. Put all 5 subsamples in one large Whirl-pak or Ziplock bag. The mosses are 95% water, so when they dry down they get quite light. Collect enough to have several 10’s of g of dry material at the end. In total, this will be a healthy hand full. A double hand full would be even better. NOTE: A purist would wear disposable lab gloves to do all of these procedures. If can do so, great. If it’s a bother, don’t.
