Non esiste uno standard stereotipato per le segherie, ma esistono molti layout e combinazioni diverse di macchinari e potenza. Oltre alle differenze meccaniche delle varie segherie, quando i tronchi vengono trasformati in legname sono coinvolte molte altre variabili. Queste includono il tipo di specie tagliata, le dimensioni e la qualità dei tronchi, la qualità del legname e il mercato di destinazione. In tali circostanze è difficile stabilire medie e persino effettuare confronti. Nel presente studio sono stati determinati i rapporti di conversione del legname verde di tre specie locali, ovvero Piptadeniastrum africanum, Nesorgodonia papaverifera e Triplochiton scleroxylon. Queste specie sono state lavorate con gli stessi metodi di segatura. I rapporti di conversione o l'efficienza delle tre specie, N. papaverifera, P. africanum e T. scleroxylon, hanno prodotto rispettivamente il 42,73%, il 23,96% e il 24,03%. È stata riscontrata una differenza significativa tra l'efficienza di P. africanum e N. papaverifera, nonché tra N. papaverifera e T. scleroxylon. Le rese di T. scleroxylon e P. africanum non erano significativamente diverse. Le rese erano correlate alle condizioni del tronco prima della lavorazione.
