Two new shoreland toe protection products were added to the research project this year.
These include ShoreSocks / Corn Sox and flax logs. Both were installed along the eroding shoreline in late spring. The flax logs are similar to coco logs, but with flax stalks replacing the coconut fiber filling and a photo-degradable poly netting replacing the jute netting surrounding the coco logs. These are anchored along the shore with wooden stakes. The ShoreSocks / Corn Sox are made of corn husk bales placed in photo-degradable woven bags. The bags are held together with ropes strung through sleeves at the top and bottom of the bags. They are anchored to the shore with wooden stakes. Once the bales are saturated, plants can be installed in them. Only licensed and trained dealers of this product are allowed to install ShoreSocks / Corn Sox. These products have not been tested for long-term, site specific erosion control (i.e., Does the shoreline remain stable when fiber filling and cover have decomposed in three to five years?) See Table 2 for a comparison of all the toe treatments used in the project.
