Erosion control - Threadbo trail

Walking at Threadbo on the weekend I noticed a net used to control erosion. It was made of heavy duty plastic.

Some of the readings I have been looking at can be found in Google Scholar. In the last couple of years I have used this database to find many articles and books on various subjects. However, the problem is with books you cannot print entire slabs; but at least it is a starting point to then go to libraries.
There are many fascinating anthropological and archeological papers on net making. Some of the search words I have used are knotting, knitting, netmaking. Actually many patents come up and these are quite interesting on the application on netting in industrial and commercial situations.
If you have acces to ANU’s JSTOR database there is a font of reading there. Later today I will post some readings.
