Li-Pipepes tsa Spiral seam bakeng sa setšoantšo sa lipompo tsa methapo ea metsi

Tlhaloso e khutšoane:

Kaho ea libaka tsa li-aproloji, thepa e sebelisitsoeng ho bapala karolo ea bohlokoa le ho phethahala ha morero ona. Lintho tse ling tse bohlokoa haholo ho indasteri ea insusts ke phala e halikiloeng. Li-pipes tsena li sebelisoa hangata lits'ebetsong tsa metsi le lipeipi tsa khase, ho kenyelletsa le lipeipi tsa tšepe tse ngata, li bohlokoa ho netefatsa ts'ebetso ea tsona. Ka blog ena, re tla nka karolo e tebileng hoTlhaloso ea PIPRAD e ngotsoeng le bohlokoa ba bona indastering ea kaho.

Ha re nahana ka litlhaloso tsa sekhobo sa sekhobi sa sekhele sa Spiral, ho bohlokoa ho shebisisa lintlha tsa bohlokoa tse kang bophara, mafika a botenya le sehlopha sa mafika le sehlopha sa thepa.
