Line-Intercept Sampling
Line-Intercept Sampling (LIS) is an ecological field method developed by Richard H. Canfield in 1941 for estimating vegetation cover, plant density, and structural characteristics in rangeland and forest surveys. By laying a linear transect across a study area and recording all plants intersecting the line, LIS provides efficient, unbiased estimates without requiring plots or quadrats.
Rekodi ya chanzo
Nukuu zimehamishwa kwa uhalisi kutoka kwa rekodi ya chanzo cha mbinu. Hakuna uthibitisho wa kiwango cha dai unaodokezwa kutoka kwao.

Madai yaliyotunzwa
Madai yamehifadhiwa katika daftari la ushahidi, kila moja ikiwa na tathmini yake.
Mwonekano huu haubuni tathmini ya dai wakati daftari haina yoyote.
Mbinu zinazohusiana
Zilizotengenezwa kutoka kwa grafu ya mbinu na kuonyeshwa kama uhusiano uliopendekezwa na mashine — hakuna dai la ushahidi linalodokezwa.
